Contractor Combat FAQ
When should I send a demand letter?
After reasonable attempts to resolve the issue directly fail. Give them a chance to fix problems, but don't wait indefinitely.
What if they're unlicensed?
That could be a major advantage. Many states void contracts with unlicensed contractors or allow full refund of payments made.
Can I withhold final payment for incomplete work?
Generally yes, especially if there's a written contract. Document the incomplete items and the amount you're withholding.
What if they filed a mechanic's lien?
You may still have claims against them. Dispute the lien if work wasn't completed satisfactorily. Consider consulting an attorney.
Should I get repair estimates from other contractors?
Yes. Independent estimates document the cost to fix problems and show what proper work should cost.
What about permits they never got?
Unpermitted work creates serious liability. The contractor may be required to obtain permits or undo work at their expense.
Can I recover more than my actual damages?
Often yes. Consumer protection laws may allow double or triple damages, plus attorney fees for contractor fraud or violations.
