Homes, garages and shops across Pleasant Hill
Pleasant Hill sits in the middle of Contra Costa County along I-680, and most of our calls there come from neighborhoods where the houses have been around a while. A lot of them are single-story homes with attached garages that have held decades of cars, workbenches and storage, and plenty have had a sealer, paint or a store-bought kit rolled on at some point. We also hear from shops, offices and rental owners around town, and the same kind of work carries right over into Concord and Walnut Creek.
We come in from Antioch, and the same crew works in Martinez and the other cities nearby. On older floors like these, the job usually turns on what's already on the slab and how sound the concrete is underneath, so I look at that before we ever talk about colors.
Our services in Pleasant Hill, CA
- Garage Floor Coatings
Older garages here carry years of oil stains and patch work. We grind the slab so the coating grips, fill the cracks and leave a floor that mops clean.
- Stained Concrete Flooring
When carpet or tile comes up and leaves a sound slab, stained concrete flooring can make it the finished floor. We strip the glue, test a color patch and seal it.
- Concrete Grinding & Surface Preparation
Slabs here often carry old sealers, paint or thin coatings that a new finish won't stick to. We grind to clean concrete first, because that decides how long the floor lasts.
- Concrete Resurfacing & Overlays
Patios, walkways and porches here often show settling cracks and pitted tops. Where the slab is still solid, we patch and overlay it rather than tear it out.
- Commercial & Industrial Epoxy Floor Coatings
Shops, offices and service businesses in Pleasant Hill put carts, foot traffic and spills on bare concrete. We plan the coating around your schedule so the business keeps running.
- Polished Concrete Flooring
Bare slabs in shops, studios and converted garages often only need grinding and polishing. We grind in steps to the shine you pick and seal it against dust and stains.
What clay ground asks of Pleasant Hill slabs
There's a lot of clay soil across Pleasant Hill. That's a general finding for the city, not a report on your lot, but it matches what we see on floors here. Clay swells when it's wet and shrinks when it dries, so slabs on it tend to crack and shift, and moisture can work up through the concrete from below. A coating can't hold a moving slab still, and moisture under it is the usual reason a floor lifts, so before I recommend anything I check whether the cracks are still moving and test the slab for moisture. If a crack is active, we talk about how to handle it instead of just covering it.
The other thing we run into on older houses here is whatever went on the floor before. Old sealer, paint and peeling DIY kits have to come off because a new coating only bonds to clean, open concrete, so we grind it out and vacuum the dust as we go and leave your garage clean.

Pleasant Hill floor questions answered
How do I know if my floor coating project needs a permit in Pleasant Hill?
Call the city's Building Division at (925) 671-5200, because the city says a permit is needed for any work that physically changes or adds structures to a property and tells you to call when in doubt. The city lists driveways, pathways and patios as ground work that needs no building permit, but it doesn't speak to coating or polishing an existing floor. If your job calls for a permit, I'll tell you at the estimate and we'll settle who gets it before work starts, and if I'm not sure, I check with the city first.
Does a flooring contractor need a license to work in Pleasant Hill?
In most cases, yes. The state licensing board requires a contractor's license when a job needs a building permit, uses any workers besides the contractor, or costs $1,000 or more in labor and materials, a line that used to sit at $500. The city also requires a business license from anyone doing business in Pleasant Hill, including contractors whose office is outside the city. We're licensed and insured.
How much does a garage floor coating cost in Pleasant Hill?
Your price comes down to the size of the floor, how much grinding and crack repair the slab needs, and which finish you pick, from a sealer or stain up to a full epoxy or polyaspartic coating. On older Pleasant Hill garages, removing an old coating and fixing cracks is usually the biggest swing, and those same things, plus how long the coating needs to cure, decide how long we're there. I'll put the number in a written estimate after I've seen the slab.
What causes epoxy to peel off a garage floor?
It's usually the prep or moisture, not the coating itself. Epoxy rolled onto a slab that wasn't ground, or over old sealer, oil or dust, has nothing to grip, and moisture coming up from below, which the clay ground here can add to, pushes it off from underneath. That's why we grind and test the slab before choosing what goes down.
What hours can a flooring crew work in Pleasant Hill?
The city allows construction work Monday through Friday from 7:30 a.m. to 7:00 p.m., and Saturday and Sunday from 9:00 a.m. to 6:00 p.m. Emergency work falls outside that limit. We keep grinding and other loud work inside those hours, so our equipment isn't running before your neighbors are up.
Does living in a Pleasant Hill flood zone affect a floor project?
It can, because the city says improvements in the floodplain may require a Floodplain Development Permit. FEMA has mapped flood hazard areas in Pleasant Hill with about 700 homes inside them, so if yours is one, check with the city before work starts. For a garage that takes water now and then, it also changes which coating I'd recommend.
