Free Soundproofing Contractor
Service Agreement
One missed acoustic seal can turn a fifty-thousand-dollar project into a total loss and a court date when the client claims it’s still 'too loud.' If you don't define decibel drop in writing, you’re basically handing the homeowner a blank check to sue you for their own unrealistic expectations.
Pro Contractor Tip
Include a 'Performance Tolerance' clause that specifies you are hitting lab-tested STC ratings, not subjective 'silence,' or you'll be chasing ghosts on your own dime forever.
Why use a written agreement?
Handshake deals are risky. As a Soundproofing Contractor, "scope creep" is your biggest enemy. A clear agreement ensures everyone agrees on the deliverables before money changes hands.

Frequently Asked Questions
The client is complaining they can still hear a lawnmower outside; am I liable?
Only if you were dumb enough to promise 'total silence.' Use your contract to specify exactly which frequencies you're mitigating and what the decibel reduction targets are so subjective complaints don't hold up your final payment.
How do I handle it when the client buys their own 'cheap' acoustic foam and expects me to install it?
Refuse the liability. Your agreement should state that you only warrant labor on materials you source; if they want to use junk, the contract needs to waive your performance guarantee immediately.
I'm losing days because the HVAC guys haven't finished their ductwork; how do I get paid for the delay?
You don't work for free. Your contract needs a 'Site Readiness' clause that triggers a daily standby fee if you show up and can't hang board because the other trades are dragging their feet.
