Basement Floor Epoxy in Boise
Seal and finish basement concrete with a coating that's bright, easy to clean and built around moisture testing first.
Get a Free QuoteMost Treasure Valley homes are built on slabs or crawlspaces, but basements are common in older Boise neighborhoods like the North End and the Bench, and in some newer custom homes in the foothills and Eagle. Bare basement concrete is dusty, cold-looking and hard to keep clean.
An epoxy floor turns it into a usable space — a home gym, workshop, laundry area, storage room or rec room — with a seamless surface you can mop.

Moisture comes first
Basement slabs sit against soil, and moisture vapor moving up through the concrete is the most common reason basement coatings bubble or peel. Before we quote, we check the slab for moisture and look for efflorescence (white powder), damp spots and old coatings. If moisture is present, we recommend a moisture-mitigating epoxy primer under the finish. If there's active water intrusion, that has to be fixed first — a coating can't stop a leak.
Never coat over a basement slab that's actively wet or seeping. Fix drainage or leaks first, then coat.
Finish options
- Flake: textured, hides imperfections, good grip — great for gyms, laundry and storage
- Metallic: high-gloss showpiece for rec rooms, bars and theaters — see metallic epoxy
- Solid color: clean, affordable, easy to keep bright
Old paint, glue and tile adhesive
Older basements often have painted concrete, carpet glue or mastic from old tile. All of it has to come off with a diamond grinder so the new coating bonds to sound concrete. Some older black mastics can contain asbestos; if we suspect that, we'll recommend testing before any grinding. See concrete repair & floor prep.
Access, ventilation and timing
Basement installs need a path for grinding equipment and good ventilation while coatings cure. We plan the install so you can keep using the rest of the house, and we use dust-extraction vacuums on all grinding.
What it typically costs
Basement coatings typically run about $3–$8 per sq ft for solid or flake systems and $7–$12 for metallic, plus $1–$3 per sq ft if moisture mitigation is needed. Typical ranges only — your price comes from a free on-site estimate.
Basement Floor Epoxy FAQ
Can you epoxy a basement floor that gets damp?
Only after the source of moisture is addressed. Slabs with moisture vapor, but no standing water or leaks, can usually be coated with a moisture-mitigating primer underneath. Actively wet or seeping slabs need drainage or waterproofing fixes first, or any coating will fail.
How much does basement floor epoxy cost?
Basement floors typically run about $3–$8 per sq ft for solid or flake systems and $7–$12 for metallic, plus roughly $1–$3 per sq ft if moisture mitigation or heavy adhesive removal is needed. Every basement is quoted on site.
Is epoxy warm underfoot?
Epoxy doesn't add insulation, so it feels about like the concrete under it. Many homeowners use area rugs in living spaces and leave the coated floor exposed in gyms, laundry and storage areas where easy cleaning matters most.
