5 Best Loyalty Apps for Window Cleaners in 2026

A window cleaning round is the most valuable asset a window cleaner owns. Not the van, not the water-fed pole, not the pure water system. The round — the list of customers who expect you every four, six, or eight weeks, rain or shine, year after year.

Building a round takes years. Losing customers from it takes moments. A competitor drops a leaflet through the door offering £2 less. A customer moves house and forgets to tell you. Someone sees a Facebook post from a newer, shinier operation and switches without thinking twice. A missed clean (because it rained, because you were ill, because you were overbooked) becomes two missed cleans, and the customer assumes you've stopped coming.

The maddening thing is that most customers leave their window cleaner not because they're unhappy, but because the relationship was held together by nothing more than a routine. No communication between visits. No reward for loyalty. No way to reach the customer directly when weather disrupts the schedule or when you're offering a new service. The entire relationship exists in the customer's vague memory that "the window cleaner comes on the second Thursday of the month."

A digital loyalty programme gives that relationship structure. It puts your business on the customer's phone permanently. It rewards them for sticking with you instead of switching to the leaflet that just came through the door. It lets you communicate directly — schedule updates, weather delays, new service launches, referral requests — through a channel that reaches their lock screen, not their spam folder. And it turns your satisfied customers into a referral engine that grows the round without you knocking on a single door.

At Perkstar, we work with service businesses, tradespeople, and route-based operators across the UK. We've seen which retention tools protect the rounds that take years to build. This guide covers the five loyalty apps that genuinely work for window cleaners in 2026.

Why Window Cleaners Need Loyalty Differently From Any Other Service Business

Window cleaning operates under a set of dynamics that most loyalty platforms weren't designed for. Understanding them shapes the right strategy.

Your round is your revenue — and every lost customer is a permanent hole. A residential customer paying £15 every six weeks is worth roughly £130 per year. Lose 20 customers from a 200-customer round and that's £2,600 per year gone — customers you spent months acquiring through door-knocking, leafleting, and word of mouth. A loyalty programme that rewards tenure and consistency makes switching feel like abandoning earned progress. The customer who's seven cleans into their stamp card isn't going to call the bloke who dropped a leaflet through the door.

Communication between visits is your weakest point — and your biggest vulnerability. Most window cleaners have no way to contact their customers between visits except knocking on the door or leaving a note. If rain delays the schedule, the customer doesn't know. If you're offering gutter cleaning or conservatory washing, they don't know. If you want to ask for a Google review, you have to remember on the day, at the door, while juggling a squeegee. A push notification solves all of this. "Weather delay — I'll be there Thursday instead of Tuesday" takes five seconds and reaches every customer on your round directly.

Upselling is your most immediate growth opportunity. Gutters, fascias, soffits, conservatory roofs, solar panels, pressure washing driveways and patios — the average window cleaning customer could spend three to five times more with you per year if they knew you offered these services. Most don't know. A push notification ahead of autumn — "Gutter clearing season — book now before the leaves block them" — reaches your entire customer base with a service they need but didn't know you provide.

Referrals are how rounds grow — but they happen passively. "Who does your windows?" is a conversation that happens between neighbours constantly. Right now, that conversation leads to "I'll give you his number" — and then neither party follows through. A referral programme with a shareable link gives the recommendation a mechanism: the neighbour taps a link, adds your loyalty card, and you've gained a new customer without knocking on a single door.

Weather disrupts everything — and poor communication about it loses customers. A week of rain means a week of missed cleans. If customers don't know why you haven't shown up, some assume you've dropped them. Others call the next window cleaner they find on Google. A push notification — "Rain this week, I'll catch up next week, your clean is guaranteed" — manages expectations and prevents the misunderstanding that costs you customers every rainy season.

Google reviews determine whether new customers find you. When someone searches "window cleaner near me," the results are dominated by operators with strong reviews. A window cleaner with 4.9 stars and 80 reviews will get the call over one with 4.2 stars and 12 reviews — regardless of who's actually better. A loyalty programme that systematically generates reviews builds the online presence that fills gaps in the round without door-knocking.

The 5 Best Loyalty Apps for Window Cleaners

1. Perkstar

Best for: Window cleaners who want mobile wallet loyalty, round-management communication, upselling tools for additional services, and a referral programme that grows the round without door-knocking.

Perkstar gives window cleaners something they've never had: a direct, permanent communication channel to every customer on their round. Customers add a loyalty card to their Apple Wallet or Google Wallet by scanning a QR code on a card you leave after each clean, on a sticker on the window frame or door, or on a flyer you hand them when you first start their service. No app download. Ten seconds.

For window cleaners, a stamp card is the strongest primary programme — "every 8th clean earns a free one." The format is simple, visual, and perfectly suited to a regular-schedule service business. A customer who's six stamps in isn't switching to the competitor's leaflet — they're two cleans away from a free one. The stamp card creates a tangible switching cost that a verbal agreement ("I'll be back in six weeks") never could.

A points programme layers on top to capture the upselling opportunity. Points based on total spend (1 point per pound spent) mean a customer paying £15 for a window clean earns 15 points, while the same customer adding a £40 gutter clear earns 55 points. The points system makes additional services feel like earning progress rather than extra spending.

Perkstar supports eight card types. For window cleaners, the additional high-value options include a multipass (12 cleans prepaid at a discounted rate — locking the customer into a full year and providing upfront cash flow), a membership for your premium customers (a monthly direct debit covering windows, gutters, and fascias at a bundled rate), and digital gift cards (surprisingly effective — "give someone clean windows" works for housewarming gifts, elderly parents, and Christmas presents for hard-to-buy-for relatives).

The marketing toolkit is where Perkstar transforms a window cleaning business from a silent, route-based operation into an actively communicating service:

Schedule and weather updates:

"Weather delay this week — I'll catch up on Thursday/Friday. Your clean is guaranteed"
"Back on schedule after last week's rain — see you Wednesday as normal"
"Running ahead of schedule this week — I'll be there a day early, heads up"

Seasonal upselling:

"Autumn's here — gutter clearing available now. Book before the leaves pile up. Earn double points"
"Spring clean special — windows, frames, sills, and conservatory roof. Triple points on all spring packages"
"Solar panels looking cloudy? Professional solar panel cleaning — earn points on every service"

Referral growth:

"Happy with your clean? Share your referral link with a neighbour — you'll both earn a free clean"

Lapsed customer recovery:

"We haven't cleaned your windows in a while — would you like to restart? Your stamps are still here"

Each notification reaches the customer's lock screen directly. For a window cleaner who previously had no way to communicate between visits, this channel changes the entire dynamic of the customer relationship.

Geo-fenced notifications work differently for window cleaners. Set a geo-fence around the neighbourhoods on your round. When a potential customer in that area (who's been referred but hasn't yet booked) enters the zone, they receive: "Your neighbour recommended us — we're cleaning in your area this week. Want to book a first clean?"

For on-the-job use, the Scanner App lets you scan the customer's wallet card using your phone after each clean — takes three seconds at the door. Scanner App Pro isn't as critical for window cleaners as for retail (you're not doing 200 transactions a day), but the standard Scanner App is fast enough for a round-based workflow.

The referral programme is the single most valuable feature for growing a window cleaning round. Every satisfied customer knows their neighbours — and "who does your windows?" is one of the most common household recommendations. The referral link makes that conversation convert into a booked clean rather than a forgotten phone number.

Google Review rewards build the visibility that fills round gaps from search enquiries. The CRM with behavioural segmentation lets you separate your residential customers from commercial accounts, your windows-only clients from your full-service customers, and your long-term regulars from newer additions — messaging each appropriately.

Integrations with Mailgun and Twilio give you email and SMS. Pricing starts at £12 per month on a yearly plan, with a 14-day free trial requiring no credit card.

2. Jobber

Best for: Window cleaners who want a full field-service management platform with scheduling, invoicing, quoting, and basic customer retention features.

Jobber is a field-service management tool used by many window cleaners and trades businesses. It handles scheduling, route optimisation, quoting, invoicing, payments, and client communication. The platform includes automated follow-ups, service reminders, and the ability to request reviews.

For a window cleaner who needs a complete business management system — scheduling, invoicing, and customer communication all in one place — Jobber offers genuine depth. The recurring job scheduling is designed for route-based work.

The loyalty-specific features are limited. Jobber doesn't offer a stamp card, points programme, or any reward mechanic. There's no Apple Wallet or Google Wallet loyalty card on the customer's phone. No referral programme with reward tracking. No push notifications to lock screens for upselling or weather updates (communication happens through email and SMS within Jobber). No seasonal promotion tools. No digital gift cards.

Jobber is a strong business management tool. But for window cleaners who want loyalty to actively reward customer tenure, incentivise referrals, and upsell additional services through direct push notifications, a dedicated loyalty platform alongside Jobber delivers what the management tool alone can't.

3. Square Loyalty

Best for: Window cleaners processing all payments through Square that want automatic loyalty tracking.

Square Loyalty integrates with Square POS. Customers earn points when they pay — no scanning, no extra step. For a window cleaner using Square for on-site card payments, loyalty tracking happens automatically.

Points accumulate based on spend. For a window cleaner who wants the simplest loyalty add-on to their payment system, it works.

The trade-offs are significant for a round-based business. No Apple Wallet or Google Wallet integration — nothing on the customer's phone between cleans (which might be four to eight weeks apart). No push notifications for weather delays, schedule changes, or seasonal upselling. No stamp cards for tracking clean frequency. No referral programme. No Google Review rewards. No multipass or membership for prepaid annual cleaning. You're locked to Square. For a business where communicating between visits and growing through referrals are the two highest-value loyalty functions, Square Loyalty's silence between transactions is the fundamental limitation.

4. Loopy Loyalty

Best for: Window cleaners who want a simple mobile wallet stamp card without any system dependency.

Loopy Loyalty delivers a digital stamp card through Apple Wallet and Google Wallet. No app download, real-time updates, branded card. For a window cleaner who wants a "every 8th clean is free" stamp card with a persistent wallet presence, Loopy Loyalty works.

The wallet card keeps your business visible on the customer's phone between cleans — a subtle reminder every time they open their wallet that you exist, you're reliable, and their free clean is getting closer. For a service with four-to-eight-week gaps between visits, that persistent presence has genuine defensive value against competitor leaflets.

The limitations are significant. Push notification capability is basic — lacking the scheduling and segmentation needed for weather updates, seasonal upselling, and targeted communication. No points system for rewarding additional services (gutters, conservatories, solar panels) proportionally. No multipass or membership for annual prepaid packages. No referral programme. No Google Review rewards. No CRM. A stamp card creates a switching cost, but without the communication tools to manage weather delays, promote seasonal services, and generate referrals, it addresses only one of a window cleaner's loyalty needs.

5. Stamp Me

Best for: Window cleaners who want a familiar digital punch card with QR and NFC options.

Stamp Me digitises the paper punch card. Customers collect stamps via QR code or NFC tap through the Stamp Me app. For a "clean 8 times, get one free" programme, Stamp Me delivers the basic mechanic.

The friction: customers must download the Stamp Me app. For a window cleaning customer — who interacts with you for approximately 90 seconds at the door while handing over cash or confirming the clean — downloading an app for a stamp card is disproportionately complex for the interaction. Most won't bother. Those who do may never open the app again between cleans. No push notifications for weather updates or seasonal services. No referral programme. No Google Review rewards. Basic analytics.

Real-World Scenario: How a Loyalty Programme Protects a Window Cleaning Round and Doubles Additional Service Revenue

Feature tables compare platforms. This section shows what loyalty looks like at 7am when you're loading the van, at 3pm when you've finished the round and want to grow it, and on the rainy Wednesday when you can't work but can still reach every customer on the route.

Dan is a window cleaner covering three towns in Hertfordshire. He runs a 280-customer residential round on a six-week cycle, plus 15 commercial accounts (offices, restaurants, and shops) on various schedules. His van is kitted out with a water-fed pole system and a pure water tank. His work is excellent — consistently clean windows, reliable schedule, friendly at the door.

His problems are the same ones facing every window cleaner in the UK.

First, he loses roughly 25-30 customers per year to a mix of competitor leaflets, house moves, and unexplained disappearances. Replacing them through door-knocking costs time he doesn't have and delivers an inconsistent hit rate. Each lost customer represents £130 per year in lost revenue — totalling £3,250-3,900 annually in round erosion.

Second, he offers gutter clearing, fascia cleaning, conservatory roof washing, and driveway pressure washing — but only about 15% of his window customers have ever booked an additional service. Most don't know he offers them. He mentions it at the door occasionally, but the conversation is rushed and the customer is usually mid-conversation with someone else or heading to work.

Third, he has no way to communicate with his customers between cleans. When rain delays the schedule (which happens roughly six to eight times per year), he can't tell anyone. Some customers call to ask where he is. Others assume he's stopped coming and call someone else. He estimates he loses three to five customers per year purely from weather-related miscommunication.

Month one — enrolling the round. Dan prints a small card with a QR code and leaves one at every property after each clean, tucked into the door handle or letterbox alongside his usual "windows cleaned" card. The message reads: "Scan for free window cleans — earn a stamp every time I clean. Every 8th clean is on the house." He also hands the card directly to customers who answer the door, spending 10 seconds explaining: "Scan this, it goes in your phone wallet, and you'll earn free cleans."

Over two complete round cycles (12 weeks), 165 customers enrol — roughly 59% of his residential round. The door-handle card placement works well for customers who aren't home, and the direct hand-off works even better for those who are. Enrolment continues steadily as he repeats the cycle.

Month one — the weather notification saves customers. Three weeks into the programme, a week of persistent rain hits. Dan can't clean. Previously, he'd have gone silent — customers would wonder where he was, some would call, a few would call a competitor. Now he sends a push notification on Monday morning: "Heavy rain this week — can't get the windows done safely. I'll catch up next week, your clean is guaranteed. Your stamps are waiting."

The notification reaches 165 phones. The response is immediate relief. Several customers reply via the text link: "No worries, see you next week." Nobody calls a competitor. Nobody assumes Dan has disappeared. The weather delay — which previously cost him three to five customers per year in miscommunication attrition — costs him zero.

He starts sending weather notifications every time rain disrupts the schedule. Each one takes 15 seconds to compose and prevents the silent gap that previously led to customer loss. Over a year, this single notification type saves an estimated 3-5 customers — worth £390-650 in annual revenue, more than covering the entire cost of the loyalty programme.

Month two — the autumn upsell notification transforms additional service revenue. September arrives. Gutters are starting to fill with leaves. Dan sends a push notification to his entire loyalty base: "Autumn's here — gutter clearing available now, £35-50 depending on property size. Book before November and earn double points. Don't wait until they overflow."

The notification reaches 190+ phones (the database has grown). Within two weeks, 38 customers book gutter clearing. At an average price of £40, that's £1,520 in additional revenue — from a service most of these customers didn't know he offered. Previously, Dan's autumn gutter clearing bookings came from the handful of customers he remembered to mention it to at the door. The push notification reached his entire round simultaneously.

He follows up with a spring notification: "Spring clean package — windows, frames, sills, and conservatory roof. Triple points on all spring bookings." Twenty-two customers book. A summer notification promoting solar panel cleaning generates nine bookings.

Over a year, seasonal upselling through push notifications generates roughly £4,800 in additional service revenue — more than doubling his previous additional-service income. The notifications don't require any sales conversation at the door. They reach the customer in a relaxed moment (at home, checking their phone) when they have time to consider and book.

Month two — referrals grow the round without door-knocking. Dan activates the referral programme. Existing customers earn a free clean for every neighbour who signs up for regular window cleaning. He mentions it at the door: "If any of your neighbours want their windows doing, share the link and you'll get a free clean."

Window cleaning referrals are uniquely effective because they're hyperlocal. A customer refers their next-door neighbour, who refers the house across the road. One referral from one street can cascade into three or four new customers — all on the same road, all adding to the same round route with minimal extra driving time.

In ten weeks, 24 new customers join Dan's round through referrals. That's 24 customers acquired without a single door-knock, a single leaflet, or a single hour spent on cold acquisition. At £130 per year each, those 24 customers are worth over £3,100 annually. The referral programme generates more round growth in ten weeks than Dan's typical door-knocking produces in six months.

Several referral clusters are particularly valuable: three new customers on one street (added to the existing route with zero extra travel), four in one estate (creating a dense, efficient mini-round), and two commercial referrals from a residential customer whose partner manages an office building.

Month three — Google Reviews change the phone calls. Dan turns on Google Review rewards. Customers who leave a review earn a bonus stamp. He sends a push notification after each clean cycle: "Enjoy your clean? A quick Google review helps more than you'd think — and you'll earn a bonus stamp."

Over twelve weeks, his review count goes from 18 to 75, and his rating moves from 4.5 to 4.9. For "window cleaner near me" and "window cleaning [his towns]" searches, Dan now dominates the local results. New enquiries start coming through Google — customers who need a window cleaner, search on their phone, and call the best-reviewed option they find.

In three months, 11 new customers join the round through Google enquiries — customers Dan didn't need to find because they found him. Combined with referrals, his round grows by 35 customers in four months while his annual door-knocking produced an average of 30-35 per year. The loyalty programme has matched an entire year's cold acquisition in four months.

Month three — the annual multipass locks in the best customers. Dan launches a multipass: 10 window cleans prepaid for £130 (saving £20 versus paying individually at £15 each). He promotes it via push notification to customers who've been on the round for over a year: "Been with me a while? Save £20 with an annual window cleaning pass. Pay once, sorted for the year."

Twelve customers buy the multipass. That's £1,560 in upfront revenue — and 12 customers who are now locked in for the entire year. A competitor leaflet dropping through their door is irrelevant: they've already paid. The multipass is the most effective anti-switching tool Dan has ever used.

Month three — the monthly membership for premium customers. Dan identifies his customers who use multiple services (windows + gutters + conservatory) and launches a membership: £25 per month for windows every six weeks, gutters twice per year, and frames/sills annually. He promotes it to his full-service customers.

Five customers sign up. That's £125 per month in guaranteed recurring revenue. Membership customers never leave (they're paying monthly), never switch (they've committed), and often add pressure washing or solar panel cleaning on top. The membership converts Dan's most valuable customers from ad-hoc service users into contracted clients.

Month four — lapsed customer recovery. Dan configures an automated push notification for any customer who hasn't had a clean in 10 weeks (four weeks beyond their normal six-week cycle): "Haven't seen you in a while — would you like to get back on the schedule? Your stamps are still here." Of 12 lapsed customers who receive the notification, 8 rebook. Without the notification, most would have quietly drifted off the round.

Gift cards — the surprise performer. Dan enables digital gift cards: £30 (2 cleans), £60 (4 cleans), and £130 (annual pass). "Give someone clean windows" sells better than he expected — particularly around Christmas ("give mum and dad clean windows for the year"), Mother's Day, and as housewarming gifts. Gift card sales in the first six months: £520. Every redeemed gift card is a potential new regular.

After six months:

230+ loyalty members (from a 280-customer round)
Round erosion reduced from 25-30 customers/year to approximately 10-12
Weather delay notifications: zero customers lost to rain miscommunication
Seasonal upselling generating ~£4,800/year in additional service revenue
24 new customers via referrals (£3,100+/year value, zero door-knocking)
11 new customers via Google search (reviews 18→75, rating 4.5→4.9)
12 multipass holders: £1,560 upfront + locked in for the year
5 membership subscribers: £125/month recurring
8 lapsed customers recovered through automated notification
£520 in gift card sales
Monthly cost: £12

Dan didn't buy a bigger van. Didn't hire a second cleaner. Didn't spend a single Saturday knocking on doors. He built a system that tells his customers when the rain delays him, sells gutter clearing to his entire round in one push notification, grows through referrals instead of leaflets, and locks in his best customers with prepaid passes. The round that used to erode by 25-30 customers per year now grows by 35 — and the additional services he could never find time to sell at the door now sell themselves through a notification that takes 15 seconds to write.

Three Mistakes Window Cleaners Make With Customer Retention

1. Going silent when rain disrupts the schedule. Every rainy week you can't clean is a week where some customers wonder if you've stopped coming. A push notification — "Rain this week, back next week, your clean is guaranteed" — takes 15 seconds and prevents the silent gap that costs window cleaners three to five customers per year. It's the simplest, cheapest, and most immediately impactful use of a loyalty programme for any window cleaner.

2. Only mentioning additional services at the door. Your customer is rushing to work. You're balanced on a ladder. The "I also do gutters" conversation lasts four seconds and gets forgotten immediately. A push notification ahead of autumn — "Gutter clearing available, book now" — reaches the customer in a relaxed moment, gives them time to consider, and provides a clear way to book. Window cleaners using seasonal upselling through push notifications consistently report two to three times more additional service bookings than door-step conversations produce.

3. Growing the round through door-knocking instead of referrals. Door-knocking works. It's also slow, unpredictable, and exhausting. A referral programme turns your existing satisfied customers into a growth engine. One referral from one street can cascade into three or four new customers — all on the same route, all adding to your round with minimal extra driving. The referral grows the round more efficiently than any cold acquisition method because the new customer arrives pre-sold on your reliability.
