How to Start a Window Cleaning Business as a Sole Trader

Window cleaning is one of the few trades built almost entirely on recurring work, which changes how you should think about pricing and customer relationships from day one.

Price a round, not a job

Most of your income will come from repeat visits at a set frequency, such as 4-weekly or 8-weekly, not one-off cleans. State clearly on every quote whether the price is per visit or a rolled-up estimate. Customers new to recurring service pricing sometimes assume the number shown is a one-time total.

Choose your method and explain why

Water-fed pole systems reach higher without a ladder, which is faster and safer for standard houses, but traditional squeegee cleaning still handles tight architectural gaps a pole can't reach. Naming your method on the quote is a small detail that signals you know your craft, not just that you own equipment.

Price conservatories and extras separately

Roof windows and conservatory glass take real extra time and sometimes different equipment. Fold these into a flat "whole house" rate and your pricing looks inconsistent the moment a customer with a standard house compares notes with a neighbour who has a conservatory.

Retention matters more here than in almost any other trade

A single lost recurring customer is a small but real dent in your monthly income, repeated every cycle. Reliability, turning up on the agreed day and communicating delays, earns more loyalty in this trade than almost anything else you can do.

Invest in the right equipment early

A water-fed pole system is a real upfront cost, but it pays back quickly through speed and safety compared to ladder-based cleaning on multi-storey properties. Don't delay this investment for too long once your round is established enough to justify it.

Use simple scheduling from day one

A recurring round of even a few dozen customers on different frequencies gets confusing fast without a system to track who's due when. Set this up properly from the start, because missed visits are exactly what erode trust in a recurring-service business.

Plan for access problems before they cost you time

Locked side gates, a car parked in front of a driveway window, or a dog in the garden are small, constant frictions in this trade that add up across a full day's round. Ask new customers about access at the point of booking, such as where the gate key is or whether a dog needs to be inside during the visit, instead of discovering the obstacle standing on their doorstep. A round that runs smoothly because access issues were solved in advance covers noticeably more properties in a working day than one where each stop brings a new surprise.
