Do you do takeoffs for houses in Mount Vernon?

Yes: any house in Skagit County (Mount Vernon, Burlington, Anacortes, Sedro-Woolley, La Conner and Bow), and anywhere else. You upload the plan set; nothing has to be built yet.

Which trades can I order?

Metal and shingle roofing, siding, framing, electrical, plumbing, exterior and interior painting, flooring and finish carpentry, one trade or the whole house, all measured off the same 3D model.

Does it cost more in Skagit County?

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.
