Questions

Plumbing takeoffs in Issaquah, Sammamish & Snoqualmie

Do you do plumbing takeoffs for houses in Issaquah?

Yes. Upload the plan set for a house anywhere in Issaquah, Sammamish and the Snoqualmie Valley (Issaquah, Sammamish, Snoqualmie, North Bend and Fall City), or anywhere else. Nothing has to be built yet: we measure the house on the plans.

What design numbers apply in Issaquah?

Issaquah publishes frost depth: 18 in; winter design temp.: 24 °F; energy code climate zone: 4C. The design on your plans should match them, and the takeoff follows your plans. Elevation and exposure can change them for your lot, so confirm with the building department.

Does a takeoff cost more in Issaquah, Sammamish & Snoqualmie?

No. The price is the same everywhere, and you see it before you pay. The 3D model is included, and each trade after the first in the same order is half price.

Is this an exact price?

No. It's an estimate built from your plans. Plans don't show code or inspector changes, the existing water and sewer service, or fixtures moved during construction. Anything built differently from the drawings won't be in the bid. We recommend a site visit to confirm measurements and conditions before you sign a contract or order materials.
