What to spell out on a siding contractor bid

Useful whatever you write your bids in. These are the lines that keep a job from turning into an argument.

Put it in writing
  • Square footage, material, and profile
  • House wrap, flashing, and what gets replaced behind the siding
  • Rotten sheathing priced per sheet
  • Paint or prefinished, and whether trim, soffit, and gutters are in the price

Rotten sheathing is the surprise. Put a per-sheet price on the bid and say photos are sent before it is replaced.

Questions from siding contractors

Before you sign up.

Can I bid two materials?

Yes. Put fiber cement and vinyl as two packages on one estimate. The customer picks one and signs.

How do I handle the rotten sheathing?

A per-sheet price on the bid, agreed to at signing. Send the photo, replace it, and it is already approved.

Is the signature legally binding?

Yes. The customer types their full name and clicks Accept, and we record the name, date, time, and the exact proposal they agreed to. That meets the U.S. E-SIGN Act, the same law behind DocuSign.

Does my customer need an app?

No. They tap the link in your text or email, the proposal opens in their phone's browser, they read it and sign.

Does it change what I wrote?

It fixes spelling and lays your notes out cleanly. It does not add scope, exclusions, or promises you didn't make.
