Customer name
Scope of work
Describe exactly what is included — and what is not.
Price and payment
Total: $0.00
Deposit (50%): $0.00 before work begins
Balance: $0.00 on completion
Terms
Payment
A deposit is due before work begins. The balance is due on completion. Invoices unpaid after 14 days may carry a late fee of 1.5% per month.
Changes to the work
Anything outside the scope above is a change order, priced and agreed in writing before that work starts. Verbal changes are not binding on either of us.
Access
The client agrees to provide access to the property, water and power where needed, on the agreed dates. If we cannot access the site on a scheduled day, a return visit may be charged.
Weather and delays
Work may be rescheduled for weather or conditions that make it unsafe or would affect quality. We will give as much notice as we can. Neither party is liable for delays outside their control.
Existing condition
We are not responsible for pre-existing damage or for defects revealed by the work. Where we find something unexpected, we will stop and tell you before continuing.
Insurance
The contractor carries liability insurance and will provide a certificate on request.
Cancellation
Either party may cancel in writing before work begins. Deposits cover materials already ordered and scheduling held for you, and may be non-refundable to that extent.
This is a starting point written for small home service work, not legal advice. Contract law varies by state, and some states require specific notices, licence numbers or cancellation language on residential contracts. Have a local attorney read it once before you use it for everything.
Say exactly what a clean includes
The three variables that change the job most are the ones customers assume:
Included: exterior glass, frames and sills to all ground and first floor windows, front and rear elevations. Not included: interior glass, conservatory roof, skylights, hard water stain removal, screen cleaning.
Glass only versus glass, frames and sills is a materially different amount of time per pane. Interior versus exterior is a completely different visit.
Interior access
This is where recurring residential window cleaning fails.
Exterior work needs nobody home. Interior work needs somebody there, and the two get scheduled together on a round where most customers are out.
State that interior cleaning requires access to be arranged and that a missed interior visit is not carried over free. Otherwise you are making a second trip for nothing.
Hard water staining is not dirt
Mineral etching from sprinklers and run-off does not come off with a standard clean. A customer who does not know that will conclude you cleaned badly.
Exclude it explicitly and offer restoration as a separate priced service. It is genuinely skilled work and it deserves to be sold rather than attempted for free.
Weather
You will move days for rain and high wind, and wind matters more in this trade than most because of ladder and pole work. Say so.
Frequency and route
For recurring work, state the interval and that scheduling is by route rather than by fixed date — you come on the week, not the day. That single line prevents most of the “you were supposed to come Tuesday” calls on a route business.
Running a round
Jobber at $49/mo handles recurring visits at any interval with monthly billing, and bulk-reschedules a rained-off day in a few taps. Housecall Pro adds route optimisation on Max, which on a dense storefront round is worth real money in extra stops. QuoteIQ at $29.99/mo suits a solo cleaner building a round.
Questions operators actually ask
What should a window cleaning contract include?
The panes or elevations covered, whether frames and sills are included, interior versus exterior, the frequency, access arrangements, weather terms, and what happens with hard water staining. Interior access is the clause that matters most on a recurring residential round.
Are frames and sills included?
Only if you say so. Customers assume yes; many cleaners price for glass only. State it explicitly — 'glass, frames and sills' or 'glass only' — because it changes the time per pane substantially.
How do I handle hard water staining?
Exclude it from a standard clean and offer it as a separate restoration service. Mineral etching does not come off with a normal clean and a customer expecting it to will believe you did a poor job.
What about interior access on recurring work?
State that interior cleaning requires someone present and that a missed interior visit is not made up free. Recurring residential window cleaning fails on access more than anything else.
Should commercial storefront work use the same agreement?
Broadly yes, with the frequency, the service window and any out-of-hours requirement stated. Storefront rounds are usually weekly or fortnightly and priced per visit against an agreed route.
