What Will My Home Project Cost?
Pick a trade, describe the project and choose your city; the estimator returns a cost range built from typical installed prices in the Seattle area, with the factors that move the number most. Treat the result as a planning range: a contractor's site visit turns it into a quote.

How the estimate works
Each trade starts from a base range per unit — per square foot of roof or wall, per window, per linear foot of fence, per square foot of floor area — drawn from typical installed prices in the Seattle area. Inputs that change labor or material, such as roof pitch, tear-off layers, a reconfigured layout or a steep lot, apply multipliers or fixed additions. The city factor adjusts for access and local conditions: Seattle's narrow lots and older houses tend to push labor up; newer Eastside subdivisions tend to be simpler.
Why it is a range
Two houses of the same size can differ by thousands of dollars once a contractor sees rot under the old roof, asbestos in the old siding, or a crawlspace with eighteen inches of clearance. The range covers ordinary conditions; the surprises are what a site visit is for.
What is not included
Design fees for remodels and additions are included in the remodel and addition ranges; permit fees are not, except where noted. Appliances, furniture, landscaping restoration and financing costs are excluded.
Questions about the estimator
Is my information saved?
No. The estimator runs in your browser and nothing you enter is stored or sent.
Why does Seattle come out higher for the same project?
Older houses, tighter lots and more complex permits. Not every Seattle project costs more, but the averages lean that way.
Can I use the result to judge a quote?
Yes, as a sanity check. A quote far below the range usually leaves something out; one far above it usually includes something you did not ask for, or reflects a complicated site. Ask the contractor which.
