Key takeaways:
- Ask on the second or third visit, so they can review your reliability
- Text beats a card — customers are usually out when you clean
- Ask long-standing customers to mention how long you have been coming
- Commercial reviews should talk about access and invoicing, not sparkle
- Reviews mostly confirm word of mouth rather than replacing it
Almost every guide to collecting reviews is written for trades that see a customer once. Window cleaning is the exception, and the advantage is bigger than it looks: you are not trying to catch a single fleeting moment. You have a standing relationship and a dozen visits a year, which means you can ask at the point where the customer has something genuinely useful to say.
Do not ask on the first visit
After one clean, all a customer can honestly tell the world is that the windows look better. True, but it is also what every window cleaner's reviews say, and it is not what a prospective customer is actually worried about.
What they are worried about is whether you will keep coming. Everyone has had a window cleaner who was brilliant for three months and then stopped answering the phone. By the second or third visit your customer can speak to that, and "third month, turned up on the day both times" is a far more persuasive review than "lovely job".
The customer is usually out
This is the practical problem that shapes everything. You finish, you leave, and nobody was home. Asking in person is off the table for most of your round.
Text solves it better here than in any other trade, because timing is on your side: the message lands while the customer is heading home to visibly clean windows. The result and the request arrive together, which is exactly the alignment every other trade has to engineer. A card through the door is the fallback, but it competes with the post and usually loses.
Use your long-standing customers properly
Google shows one review per person, so there is no point asking a five-year customer for a second one. What is worth asking is for them to update the one they already left.
"Been coming four years now, never missed a round" is the single most valuable sentence a window cleaner's listing can contain, because it directly answers the reliability question, and no new customer can write it. A short note to your longest-standing customers asking them to add that detail is a few minutes of work for something genuinely hard to fake.
Commercial is a different pitch
A shop, pub or office does not care about streak-free glass in the way a homeowner does. They care about whether you will show up during trading hours with a ladder in the doorway, whether you invoice properly, whether your insurance paperwork exists, and whether they will have to chase you.
So ask commercial customers for reviews about those things. The reader you are trying to convince is another business manager, and they are scanning for evidence that you are not going to be a nuisance. Commercial rounds are also far stickier than residential ones, so a handful of reviews that win those contracts pay back for years.
Reviews and word of mouth do the same job
Plenty of window cleaners build a full round on recommendations and reasonably ask why reviews matter. The answer is that the two are not alternatives. When a neighbour recommends you, the next thing that person does is search your name — and an empty or stale listing quietly undercuts the recommendation they just received.
Most of what reviews do for a trade like this is confirm something the customer already half-believes. That is not a small function. It is the difference between a recommendation that converts and one that gets second-guessed.
