Free Window Installer
Service Agreement
One bad seal or a missed measurement can turn a profitable week into a five-figure lawsuit over mold and water damage. Without a rock-solid contract, you're just one 'unhappy' homeowner away from eating the cost of custom glass and working for free.
Pro Contractor Tip
Always include a 'Hidden Conditions' clause so you aren't financially responsible for rotted framing or structural disasters discovered behind the old casing.
Why use a written agreement?
Handshake deals are risky. As a Window Installer, "scope creep" is your biggest enemy. A clear agreement ensures everyone agrees on the deliverables before money changes hands.

Frequently Asked Questions
What happens if I find rot in the studs after pulling the old window?
You stop working and show the owner the damage. A clear contract specifies that structural repairs aren't included in the install price, allowing you to bill for the extra labor and materials needed to fix the mess before the new glass goes in.
The client is nitpicking a tiny scratch on the frame and withholding the final 20% payment. How do I handle this?
Your contract should define 'Substantial Completion' and a specific 'Punch List' process. This forces the client to pay the bulk of the bill once the units are functional and weather-tight, rather than holding your entire paycheck hostage over a minor cosmetic fix.
How do I deal with homeowners who keep adding 'just one more' small window or repair while I'm on-site?
Never do 'favors' on a handshake. Use your written agreement to enforce a Change Order policy—if it isn't in the original scope of work, they sign a new price for the extra labor before you even grab your drill.
