What you can hold us to
Steven, Lemon Heights, North Tustin
A 1960s ranch home with carpet pulled off a slab poured without a vapor barrier

Steven's 1960s ranch home in Lemon Heights, North Tustin, had carpet pulled off a slab poured without a vapor barrier, and he wanted the concrete itself as the finished floor. We ran a calcium chloride moisture test first, then laid a moisture-mitigating epoxy primer, warm gray solid color, satin clear across the family room and hall, about 820 sq ft. The floor was an estimated $5,200 to $7,600 and took an estimated 2 to 3 days, with the bedrooms untouched until the last day. The result is a seamless living-room floor that will not blister when the ground stays damp in winter.
Owners go back to the slab because a coated concrete floor has no seams, no grout and no carpet pad to hold dust, pet hair or spills. In older ranch homes across North Tustin and Diamond Bar, the slab under worn carpet is often sound, and coating it costs less than tearing it out for tile. Casitas, ADUs and garage conversions in Claremont and Riverside are the other big group, since they often start as bare concrete.
Old adhesive must come off completely, or the new coating fails over it. Carpet glue, vinyl mastic and black cutback all soften under a fresh coat, and the floor peels in exactly the shape of the old room.
Grinding off old flooring typically runs 4 to 8 hours per room set and is priced inside the floor job, not sold on its own.
A solid color epoxy under a satin polyaspartic clear is the system most interior floors get, because it reads calm under furniture and lamps. Flake looks too much like a garage indoors for most owners, and metallic suits one showpiece room, like a game room in Villa Park or San Antonio Heights, rather than a whole house.
| Interior finish | Look in a living room | Upkeep |
|---|---|---|
| Solid color epoxy, satin clear | Calm, warm, seamless | Dust mop, damp mop |
| Designer metallic epoxy floor | Poured stone, high gloss | Dust mop, buff now and then |
| Polished concrete, no coating | Natural slab, soft sheen | Dust mop, occasional burnish |
Interior jobs are phased room by room, so a family stays in the house while we coat it. We seal each work zone with plastic, run dust-shrouded grinders and keep one path to the kitchen and bathroom open.
On a typical two-zone home in Eastvale or El Sobrante, day one is grinding and priming the first zone, day two is color and clear on that zone while the second is ground, and the last day finishes the second zone. Sofas, beds and dining tables go back after roughly 24 to 36 hours on polyaspartic, and we help move the heavy pieces back into each finished room. Pets and small children stay out of the work zone until the clear has cured, typically 18 to 24 hours on the epoxy coats.
An interior concrete floor coating is estimated at $3,800 to $8,000 for 600 to 1,000 sq ft, and adhesive removal, moisture mitigation and the number of rooms move the price most. Steven's family room and hall in North Tustin, an estimated $5,200 to $7,600, sat in the middle because the slab needed a moisture primer but had no tile to break out.

| Job | Est. investment | Est. duration on site |
|---|---|---|
| Interior slab floor with moisture barrier (600 to 1,000 sq ft) | Est. $3,800 to $8,000 per floor | Est. 2 to 3 days |
| Old coating removal by diamond grinding, as prep (400 to 600 sq ft) | Est. $800 to $3,000 per floor | Est. 4 to 8 hours |
| Designer metallic epoxy floor (400 to 800 sq ft) | Est. $4,500 to $12,000 per floor | Est. 3 to 4 days |
Stubborn glue or old paint typically adds an estimated $800 to $3,000 inside the floor job, depending on how many rooms carry it.
These figures are estimates for interior slabs, and they are subject to change. The written quote we give after testing and measuring sets the final price and the install schedule, and it depends on the old flooring, the moisture reading and the number of rooms.
Our owner reads every moisture test himself, which matters most on the older slabs of North Tustin and Claremont, where many were poured without a vapor retarder. After 1,187 projects in 12 years, our crews know how to grind inside a furnished house and leave it clean every evening. Each floor is covered by our 2-year workmanship warranty against peeling, delamination and hot-tire pickup, and by Coating makers' product warranties, typically 5 to 10 years on professionally installed systems, passed through to you in writing.
If you want the slab with no coating at all, ask about polished concrete floors, and for one showpiece room, a metallic epoxy floor in the game room or office.
We coat interior slabs across our 45-mile radius, with ranch homes in North Tustin, Craftsman bungalows and ADUs in Claremont and hillside homes in Diamond Bar, plus Villa Park, Yorba Linda and Eastvale on our service area page.
Many owners finish the inside and then the outside, adding stained and sealed patio concrete or a garage floor epoxy system for the cars.
An interior floor is estimated at $3,800 to $8,000 for 600 to 1,000 sq ft, and your written quote sets the final price after the moisture test.
Yes, we phase the work room by room and keep a kitchen, bedroom and bathroom open throughout.
Most homes take an estimated 2 to 3 days, with furniture back typically 24 to 36 hours after the clear coat.
Our systems run 0 to 50 g/L VOC, so the odor is light and clears quickly with the windows open.
Yes, every trace of glue and mastic is ground off before the primer, because a coating over adhesive peels.
Concrete feels cooler than carpet, which most owners in the Inland Empire like in summer, and rugs warm it up in winter.
Yes, after a moisture test, with a moisture-mitigating primer under the color coat, as in Steven's ranch home in Lemon Heights.
Your deposit is capped by California at $1,000 or 10% of the contract, whichever comes in lower.

Start to finish
We walk the slab with you, map cracks, joints and old coatings, and take moisture readings before a system is named.
The system, every coat and its thickness, the colors and the cure and return-to-service times arrive in writing.
The slab is diamond ground with dust control, cracks and joints are filled, and each coat goes down inside its recoat window.
We walk the cured floor with you, go over the care notes and tell you when cars or equipment can come back.
