Epoxy Floor Coatings
A lot of San Francisco garages and ground-floor rooms sit on concrete that several owners have patched, painted and sealed, and a coating only holds as well as what's under it. We test the slab, grind it clean and lay epoxy floor coatings chosen for the way you'll use the room.
Garage Floor Coatings
Garages tucked under the living space are common here, and they take hot tires, dropped tools and whatever drips off the car. We put down a garage coating with a little texture where you walk, so it cleans up easily and doesn't turn slick.
Concrete Floor Stripping & Removal
Older floors in the city often carry layers of paint, old tile glue or worn-out coatings, and new material won't bond to any of it. We take those layers off down to bare concrete before anything new goes down.
Polished Concrete Flooring
Shops, lofts and converted commercial spaces here often have slabs worth showing off instead of covering up. We grind and polish the concrete itself, so you get a hard, easy-to-clean floor with no coating to wear through.
Basement Flooring
Rooms and in-law units below the main floor are popular in the city, and concrete below ground can push moisture up into whatever covers it. We test for moisture first and pick a system that suits what we find, because a coating laid over a damp slab is the one most likely to bubble.
Commercial & Industrial Epoxy Floor Coatings
Small restaurants, storefronts and back kitchens here need floors that stand up to spills, carts and mopping every night. We plan the work with you around your hours and lay a commercial system matched to the traffic and cleaning the room sees.
San Francisco, CA properties and local conditions
Many of the houses we work on here are older, with the garage at street level and the living space above it, and that garage slab has usually seen a few decades of patches, oil stains, paint and hardware-store sealer. None of that shows much until a new coating goes on and lets go in spots. So I test before I quote anything, our crew finds the old layers and soft patches, and we grind down to sound concrete, because that's where most failed floors went wrong in the first place.
The city also has plenty of storefronts, flats over shops and older industrial buildings turned into work spaces. Those slabs are often uneven from years of repairs, so we level the low spots with a pourable self-leveling layer before a coating or polish goes on.
What I've learned about flooring jobs in San Francisco
The city's Department of Building Inspection issues permits for construction in San Francisco, so when a job needs one, it's their call and it has to be in hand before we start. Permit questions come up at the estimate, and when your job needs one we help you work through it with the building department and do the work to what the permit asks. We're licensed and insured, and you're welcome to ask about both. The price of a floor here usually turns on its size, what's on the slab now, how much grinding and patching it needs, any moisture we find and the system you pick. The schedule turns on that same prep, plus a permit if you need one, and the estimate is where you get the figures for your own floor.
Getting grinders and a dust vacuum up a steep driveway or through a narrow side gate takes some planning, and on blocks where parking is tight we work out where the trailer goes before the first day. We do the same work just south of the city in Daly City and South San Francisco, and we look at every slab fresh, because no two have the same history.

Call or send the form
You call (415) 918-5395 or write to us through the form, and we set up a visit at a time that works for you. It helps to tell us what the floor is now and what you'd like it to be.
I check your slab in person
I come out, look at the floor and test the slab for moisture and old coatings, and it helps if you're there to see what I find. Then I walk you through your options, what moves the price of each one and what each means for your schedule, including whether a permit question comes into it.
Our crew preps and installs
If you go ahead, our own crew prepares the concrete and puts down the system we agreed on, with a lead installer running the job day to day. Most of the work is the prep, and that's the part we don't rush.
We show you the care
When the floor is done, we walk it with you and show you how to clean and look after it. You'll know when it's ready for foot traffic and when it's ready for a car.
Frequently asked questions
How do I find out if my epoxy floor coating needs a permit in San Francisco?
Start with the city's page on which projects need a permit, which lists floor coverings outside bathrooms as work that needs none, as long as the existing required flooring stays in place. A bathroom floor, or a job where the old flooring comes out, falls outside that, so it's worth checking. I go over this with you at the estimate before anything is scheduled.
Does resurfacing a driveway or front walk need a permit in San Francisco?
The city's no-permit list includes driveways, walks, sidewalks and platforms that aren't part of an exit and sit no more than 30 inches above grade. They also have to be clear of any basement or story below, and off a required accessible route on residential buildings that must be accessible. Plenty of entry landings and walks in the city sit right over a garage or a room, so I check what's underneath before we talk about the coating.
Which building codes apply to a San Francisco permit application filed in 2026?
Any application filed on or after January 1, 2026 has to use the 2025 California Codes and the city's 2025 amendments, with no grace period. For a floor, that mostly matters when it's part of a bigger permitted remodel, because the plans have to be drawn to the current codes.
How much does a garage floor coating cost in San Francisco?
It depends on your slab more than anything, mostly on the size of the floor and how much work it needs before a coating goes on. Old paint or sealer, cracks and patches, moisture in the concrete and a tight garage under the house all add prep time, and a thicker or decorative system costs more than a basic one. I give you the number for your floor at the estimate.
What causes a garage floor coating to peel or bubble?
Most peeling and bubbling starts in the slab, not in the coating. Moisture coming up through the concrete, old paint or sealer the new coat can't grab, and a surface that was never ground open are the usual causes. Older city garages often have at least one of those, which is why I test for moisture and old coatings before we choose a system.
How do I get old paint off a garage floor before coating it?
The reliable way is to grind or strip it down to bare concrete, because a new coating bonds to the slab, not to the paint sitting on top of it. Scraping and chemical strippers tend to leave a film behind, so our crew grinds it off with equipment hooked to a vacuum to keep the dust out of the garage and the rooms above it.
About San Francisco, CA
San Francisco is a tightly built city of row houses, flats and small apartment buildings, many of them old enough that the concrete under them has been repaired more than once. Mixed in with the homes are corner stores, restaurants, auto shops and older industrial buildings now used as studios and offices, so in one week we might coat a home garage and polish a shop floor a few blocks apart.
We're based here and also work down the Peninsula and across the Bay in cities like Oakland and Berkeley. In the city itself, it's the age of the buildings that shapes the job most, because an older slab nearly always needs more prep than a newer one.
