Best Flooring-tiling in Seattle, WA — 19 Vetted Contractors

Usually not for a straightforward swap of existing flooring for new hardwood, tile, or LVP. SDCI typically requires a permit only when the work involves structural subfloor changes, new radiant heat systems, or is bundled into a larger remodel touching plumbing or electrical. Confirm with SDCI directly or ask your contractor to show you where in the permit code your specific job falls, since rules get applied on a case-by-case basis for older homes.

Go to lni.wa.gov and search their contractor registration lookup by business name or UBI number. You'll see whether their registration is active, whether they carry the required bond, and whether there are any past infractions on file. This takes about two minutes and is the single best fraud-prevention step before signing a contract.

This is almost always a moisture issue, either from a poorly ventilated crawlspace, a leak that went unnoticed, or hardwood that was installed without acclimating to indoor humidity first. Seattle's wet winters (average 37 inches of annual rainfall per NOAA regional climate data) make this more common here than in drier climates. A reputable installer should have used a moisture meter on the subfloor before installation and let the wood acclimate for at least several days on-site.

Engineered hardwood tends to perform better in Seattle's humidity swings because its plywood-based core is more dimensionally stable than solid wood, making it less prone to gapping in winter or slight swelling in damp months. Solid hardwood still works fine in climate-controlled upper floors, but for basements, ground-floor rooms near crawlspaces, or homes without great humidity control, engineered is usually the safer call.

For a standard bathroom (roughly 40-60 square feet of floor plus a shower surround), total costs including materials, labor, waterproofing membrane, and basic demo typically run $4,500-$9,000, varying with tile choice and whether plumbing fixtures need to move. Large-format porcelain tile and custom niches or patterns push costs toward the higher end. Get itemized quotes since bathroom jobs have more hidden variables than open-floor installs.

Possibly. Vinyl tile and some adhesives installed before the early 1980s in this region sometimes contain asbestos. Per the Washington State Department of Health, undisturbed asbestos flooring in good condition is generally low-risk, but cutting, sanding, or removing it without testing first can release fibers. Have a sample tested before any demo work begins, and use a certified abatement contractor if asbestos is confirmed.

A single room (bedroom or living room, roughly 200-300 square feet) usually takes 1-3 days for hardwood or LVP, and 2-4 days for tile once you include curing time for thinset and grout. Whole-house hardwood refinishing typically takes 3-5 days including drying time between coats, and you'll generally need to stay off the floors, and sometimes out of the house, during the finish-curing period.
