We install a variety of basement-ready floor systems that meet Seattle’s needs for durability, moisture resistance, and comfort.
What We Install:
- Water-resistant vinyl (LVP/LVT) – Ideal for busy family spaces or rental units.
- Epoxy basement floor coating – Seamless, durable, and modern.
- Rubber or interlocking gym flooring – Damp-proof and impact-resilient for exercise areas.
- Basement carpet – Berber, frieze, or carpet-tile styles for warmth and sound control.
- Tile or engineered wood – Hard-surface style with moisture resistance.
How We Ensure Your Floor Holds Up:
- Concrete prep – Assess flatness, repair cracks, apply vapor barrier if needed (Seattle humidity demands it).
- Waterproof first – Especially under carpet or wood; tie into sump or drainage systems when applicable.
- Match to use case – Soft warmth in family rooms, slick durability in game rooms, hygienic vinyl for rentals.
- Full install package – Includes underlay, leveling, moisture membrane, and quality trims for a neat, quiet, inspection-ready finish.
Why It Matters in Seattle: Basements here need flooring that resists moisture and meets building codes for slip resistance and indoor air quality. By installing over concrete to ANSI/TCNA prep and seal guidelines, we keep your home safe, dry, and comfortable.

How we work
We keep things simple, clear, and contractor-to-homeowner direct:
Initial walkthrough & substrate review – We measure slab flatness, note moisture spots, and discuss your use-case (gym, rec room, rental).
Material recommendation – We match your needs for warmth, water resistance, aesthetics, and budget.
Prep & plan – Confirm leveling strategy, vapor barrier placement, drain tie-in, and note any permit or O&M requirements (including under-slab drainage if applicable).
Flooring install:
- Concrete prep – Minor leveling, crack repair, and vapor taping.
- Material install – Vinyl click-lock, epoxy pour, carpet glue-down, or tile set.
- Finish details – Trim, transitions, and final moisture test if needed.
Final walk-through & care tips – We walk the finished space with you, explain maintenance tips for longevity, and hand over a clean, itemized invoice.
We aim for clarity, craftsmanship, and zero fluff—because basements don’t get second chances.
Basement flooring materials
We choose materials that perform in Seattle’s climate and stand the test of time:
Windows – Andersen or Milgard egress models with fixed bottom and crank-top operation, sealed for easy cleaning and smooth function.
Window Wells – Pre-cast steel or polymer systems from Boman Kemp (Easy-Well™) for quick installation and long-term durability.
Drainage – Tie directly into an existing foundation drain or install a local French drain connection for proper water management.
Seals & Flashing – High-quality waterproof membranes, below-grade-rated sealants, and sill pans to keep water out for the life of the window.
Ladders/Steps – Integrated aluminum rungs, at least 12″ wide, spaced no more than 18″ apart to meet egress code.
Local Supply Sources (Edmonds-Area) – We often stock at Edmonds Bowl Ace Hardware, Beacon Building Products – Edmonds, and Builder Showroom. Keeping materials local keeps the project moving.
We sound like builders, not marketers—this is how we’d talk on site.
