Soft wash agreements and damage waivers, signed in the driveway
Most pressure washing jobs are sold in the driveway, from a price you worked out while walking the house. The paperwork that protects you is short: what you'll clean and how, what was already damaged before the wand came out, and whose water you're using. SignMaster gets it signed on your phone before the hose is unrolled, and sends the rest by link.

What a wash company gets signed
- Estimate and service agreementEach surface on its own line: house wash, driveway, deck, fence, roof. Say soft wash or pressure wash for each, the price, and whether you're using the customer's spigot. The estimate acceptance form is a good base.
- Pre-existing conditions waiverOxidized siding that will chalk, loose paint, failed window seals, cracked or etched concrete. The customer initials each line you ticked, so the peeling trim isn't blamed on your crew.
- Plant and runoff acknowledgmentSoft wash mixes are hard on plants. Put in writing that you'll pre-wet and rinse the beds, and that the customer will move potted plants, cover the fish pond and keep pets inside.
- Roof cleaning releaseWalking a roof and treating shingles for black streaks carries its own risks. Keep it as a separate page the customer signs only when the roof is on the ticket.
- Commercial wash contractStorefronts, drive-thrus and dumpster pads: the schedule, after-hours access, and how wash water is collected where the city requires it.
- Fleet washing agreementUnits per visit, the price per truck or trailer, the yard you wash in, and what you charge when the vehicles aren't there on wash day.
The walk-around before you start
Damage disputes in this trade usually start with a stain or a crack that was there before you arrived. Do the walk-around with the homeowner and put what you find on the record while they're standing next to you. A Photo field opens the phone's camera during signing and prints the picture inside the signed PDF, so the cracked step or the chalky north wall sits on the same page as the customer's initials.

Open the job template
Pick your house wash template on your phone. Checkboxes list the surfaces, and a calculated field multiplies square feet by your rate and adds the extras, so the total is right before anyone signs.
- 2
Mark what's already there
Go down the conditions list with the homeowner, who ticks what you both see. The roof release's fields appear only when the roof box is ticked, and a text field takes anything unusual, like a cracked skylight.

Hand over the phone
Choose Sign in person. The homeowner accepts the e-signature consent, initials each condition and signs. In the iPhone and iPad app, only your Face ID or passcode takes the phone back.

The other owner signs by link
Add a second signer who gets an email and signs from any phone, with no account. Both signatures land in the same envelope, SignMaster's word for one send.
When the last person signs, everyone gets the sealed PDF with a certificate of completion: who signed, when, from which IP address, and a SHA-256 fingerprint of the original file.
Selling door to door after a job
Knocking on the neighbors' doors while the driveway dries fills next week, and brings a federal rule with it. Under the FTC's Cooling-Off Rule, a sale of $25 or more made at the buyer's home can generally be cancelled until midnight of the third business day, and the seller has to tell the buyer about that right and hand over a cancellation form. Add the notice of cancellation form to the same envelope as the agreement, with wording your lawyer has checked, so every rep gives it out the same way.
Commercial accounts and spring re-booking
A property manager or a restaurant group rarely signs in the parking lot. Send the contract by link with a signing order: the site manager first, then whoever approves the spend, with accounts payable as a CC who gets the finished copy. If the manager hands it off to someone else, reassign the signer instead of starting over.
Every spring, last year's house washes are the easiest jobs to sell again. Export last season's customers to a CSV and bulk send a re-booking agreement with each address and price in labeled text boxes. Each row becomes its own envelope, and the batch shows who has signed. Solo sends up to 250 rows at once, Crew 500 and Company 1000.
Pricing for a wash crew
Solo is $15 a month for an owner-operator, with unlimited envelopes. Crew is $49 a month for 5 people, so your estimators and the office share one set of templates, and each extra person is $8 a month. Free covers 3 envelopes a month, enough to try it on real jobs. New workspaces get 14 days of Crew free. See every plan.
What SignMaster doesn't do
- It doesn't measure surfaces, price jobs or schedule crews. Bring your number from your estimating app or your tape.
- It doesn't take deposits or card payments.
- It emails signing links. To text one, use Copy link and send it from your own phone.
- It can't tell you your city's wash water rules or what your insurer expects on roofs. Ask them.
Questions? Answers.
Do I need a waiver before pressure washing a house?
No law requires one, but a signed list of pre-existing conditions is your best answer to a damage claim: what was cracked, peeling or oxidized before you started, initialed by the customer.
Can a homeowner sign the estimate in the driveway?
Yes. Fill the template on your phone, choose Sign in person and hand it over. They sign without an account, and both of you get the signed PDF by email when the envelope is complete.
Can I re-book all of last year's customers at once?
Yes, on any paid plan. Bulk send a re-booking template from a CSV of last season's jobs, and each customer gets their own envelope with their address and price filled in.
Can a property manager sign a commercial contract from the office?
Yes. Send it by link with a signing order so the site manager signs first and the person who approves the spend signs next. Accounts payable can be a CC who receives the signed copy.
