Frequently Asked Questions

How much does hardwood floor installation cost in Seattle?

Solid hardwood installation in Seattle runs $8–$15 per square foot installed. Engineered hardwood is $5–$10/sq ft; luxury vinyl plank $4–$8/sq ft; carpet $3–$7/sq ft. Most Seattle flooring companies offer free in-home estimates including subfloor assessment.

Hardwood vs luxury vinyl plank — which is better?

Hardwood adds more resale value and can be refinished multiple times. LVP is 100% waterproof, more durable against scratches, and easier to install. For kitchens, bathrooms, or homes with pets and kids, LVP is often the smarter choice. Your Seattle flooring specialist can walk you through both options.

How long does floor installation take?

A typical 1,000 sq ft installation takes 1–3 days for an experienced Seattle flooring crew. Add time for subfloor prep and acclimation (hardwood needs 3–5 days to acclimate to your home's humidity before installation).

Can hardwood floors be refinished instead of replaced?

Yes — solid hardwood can typically be sanded and refinished 3–5 times over its lifetime. Refinishing costs $3–$5 per square foot, a fraction of replacement cost. A Seattle flooring company can assess your floor's thickness and condition to see if it's a candidate.

What subfloor conditions are needed for new flooring?

Your subfloor must be dry, level (within 3/16" over 10 feet), structurally sound, and free of squeaks. Moisture is the enemy of hardwood and laminate — your Seattle flooring installer should conduct a moisture test before installation begins.
