BEFORE YOU COMPARE
Give each provider
the same starting point.
This is a planning worksheet, not repair advice or an emergency service. If there is an immediate danger, contact the appropriate local emergency service.
02 / SCOPE
Compare the same job.
Ask for the work, materials, price and expected completion in writing. Ask why a quote differs substantially from the others; a low figure alone does not settle the choice.
03 / OPEN QUESTIONS
Keep unknowns visible.
Use “unknown” for anything a quote does not explain. An empty fee line is not evidence that the fee is zero. Bring your unanswered questions to the provider.
Written-estimate guidance: Federal Trade Commission.
PRINTABLE WORKSHEET

CHECK THE ARITHMETIC
Total = base price + additional fees + quoted tax − discount. Add only amounts that are not already included. A deposit is part of the total, not an additional charge. Remaining balance = total − deposit. If a figure is unknown, the comparison is incomplete.
All amounts should use the same currency. This worksheet does not estimate market prices, calculate taxes, verify a contractor or recommend a quote.
BEFORE YOU AGREE
Resolve the blanks
in writing.
Check licensing with the relevant state or county authority and ask for insurance evidence. Read the agreement, including dates and payment terms. Avoid full payment before work starts. Local requirements and deposit limits vary.
See the FTC’s contractor guidance and your local consumer-protection office.
