HOW WE WORK
The Unsexy Layer That Saves Floors
Stone and grout get penetrating sealers that repel oil and water without changing appearance, reapplied on schedules we document. Enhancing sealers are available where you want color deepened.
Wet areas get true waterproofing, sheet or liquid membranes tied into drains and curbs, because sealer on tile was never the thing keeping water out of your framing.

FAQS
FAQs About Floor Sealing & Waterproofing in Seattle
Floor sealing & waterproofing in Seattle typically runs $1 to $4 per square foot for sealing; waterproofing quoted by assembly. Final pricing depends on surface porosity, product system, wet-area detailing, and access. Seattle Flooring Company provides free on-site estimates with fixed, line-item quotes, so the price we quote is the price you pay.
Sealing visits typically finish in hours with same-day cure; waterproofing assemblies follow their build schedule, usually adding a day.
High-use kitchens and showers: every 1 to 2 years; lower-traffic stone: every 3 to 5. The water-drop test tells the truth, when drops stop beading and start darkening the surface, protection has expired. We tag every job with its recommended renewal date.
