Does a low quote mean poor quality?

Not necessarily. It most often means a narrower scope. Line up the exclusions before drawing conclusions.

Can Home Project Copilot tell me if I'm overpaying?

It shows where your quote sits relative to a benchmark range and flags scope gaps that commonly explain price differences. It does not appraise work or certify pricing.

How much should my project cost? Typical ranges explained

National averages are a starting point, not an answer. Labor markets, access, material grade, and hidden repairs move real prices far more than the headline number suggests. Here is how to read a range without over-trusting it.

Use a range, then adjust for your market

Construction costs in high-cost metros can run 20–40% above the national average, while parts of the South and Midwest sit below it. A quote that looks high nationally may be perfectly normal locally — and vice versa.

Typical complete-job ranges (national)

Roof replacement: $9,000–$26,000 (about $4.50–$11.00 per sq. ft.)
Siding replacement: $12,000–$38,000 (vinyl $6–$13/sq. ft.; fiber cement $10–$20/sq. ft.)
Seamless gutters: $1,200–$4,500 ($8–$20 per linear foot)
Window replacement: $600–$1,600 per window installed
Deck build: $30–$60/sq. ft. pressure-treated; $50–$95/sq. ft. composite
Mid-range kitchen remodel: $25,000–$85,000
Mid-range bathroom remodel: $12,000–$40,000

Where estimating data comes from

Professional estimators often use licensed unit-cost databases such as RSMeans, which price out labor and material by assembly and location factor. Those datasets are subscription-licensed and intended for professional estimating, so consumer-facing tools typically publish editorial ranges compiled from public cost surveys instead.

Either way, a database gives you a sanity check — not a bid. Two contractors can both be fairly priced and differ by thousands because their scope differs.

Compare scope before you compare price

Is tear-off, disposal, and permitting included?
Is the material grade identical across bids?
Are structural or substrate repairs allowanced or excluded?
Is the warranty term the same?
