Epoxy Flooring in San Rafael, CA

Concrete between the hills and the bay

San Rafael is a town of contrasts, and its concrete shows every one of them. Up in the hills, homes are tucked into steep lots where garages are cut into the slope and runoff from winter storms flows right past the door. Down by the canal and the shoreline, slabs sit on soft bay fill where the water table is close to the surface and salt air drifts in on the afternoon breeze. In between, the older flat neighborhoods near downtown hold bungalows and cottages with narrow driveways and small garages poured generations ago. Each of these settings stresses a floor in a different way, and a coating that ignores those differences rarely lasts.

Our approach is simple. We read the slab before we sell anything. We measure moisture, look for cracks and settling, check for old sealers or paint and decide on a system that fits the floor and the way you use it. Then we grind the concrete to open it up, repair what needs repair and build the coating in layers. That process takes more time than a weekend kit, but it is the difference between a floor that peels in a year and one that still looks sharp a decade later.

Our process from first visit to final walk

The first step is a free visit. We measure the space, take moisture readings in several spots and talk about what you want the floor to do. Some people want a showroom look, some want something that hides mud from hiking boots and dog paws, and some just want a floor that stops shedding dust onto everything stored in the garage. We put the plan in writing so you can compare it fairly.

On install day we protect walls, doors and anything that stays in the space. We diamond grind the slab with vacuum-attached equipment to remove the weak top layer and leave a profile the coating can grip. Cracks are routed and filled, chips and spalls get patched and the whole floor is vacuumed clean. Then we apply the primer or base coat, broadcast flake or pigment if the system calls for it and finish with a durable topcoat. Before we leave, we walk the floor with you and go over cure times and care.

What we install

We work in single-family homes, condos, rentals and businesses all across town.

Garage floors

Residential garages are the core of our work. Choose a solid-color garage floor epoxy, a full broadcast flake floor with texture and grip, or a polyaspartic coating when you want the garage back in service fast.

Interiors and decorative work

Converted garages, home offices, studios and basements are great places for metallic epoxy floors. We also pour epoxy countertops for kitchens, bars, bathrooms and workbenches.

Commercial floors

Restaurants, auto shops, fitness studios, medical offices and warehouses rely on our commercial epoxy flooring. Retail spaces and offices with exposed slabs often choose polished concrete instead.

Exterior surfaces and repairs

Steep driveways get slip-resistant driveway coatings, decks and walks get breathable concrete sealing and failing floors from other installers get fixed by our epoxy floor repair service.

The homes we see most

The hillside neighborhoods are full of mid-century homes with garages built right into the slope. Those garages often sit lower than the street, so rainwater and fine silt find their way under the door every winter. We pay close attention to the edges and the threshold on these floors, and we usually recommend a flake system or a textured topcoat so the surface stays grippy when it is wet. We also look carefully at the back wall, where the garage meets the hill, because that is where moisture tends to push through.

Closer to the water, homes and townhouses near the canal sit on fill that can settle unevenly. Cracks are common, and some slabs have a slight tilt toward a drain. We fill and stabilize those cracks before coating and we choose flexible repair materials where movement is still possible. The older bungalows and Mission-style homes near downtown bring their own challenges: thin slabs, old paint, patched sections and sometimes oil soaked deep into the concrete. Those floors need careful grinding and cleaning, but they can look new again.

Why moisture testing matters

Moisture is the biggest single cause of coating failure we see. Water vapor moves up through concrete constantly, and when it hits a coating that cannot breathe it builds pressure underneath. The result is bubbles, white haze and eventually peeling. In a town with wet winters, close groundwater near the bay and hillside runoff, it would be reckless to skip testing. We test every slab, and when readings are high we use moisture-tolerant primers or recommend a breathable system instead of a sealed one.

Durability you can count on

A properly installed floor resists hot tire pickup, oil and gasoline, road salt, cleaners and the scrape of tools and furniture. It turns a dusty, porous slab into a sealed surface that sweeps clean and brightens the room by reflecting light. For many homeowners the change in the garage is dramatic: it stops being a storage cave and becomes a usable workshop, gym or play area. For businesses, a coated floor is easier to clean, looks professional to customers and stands up to carts, forklifts and constant foot traffic.

Choosing a system

Not every floor needs the most expensive option. A family garage that mostly holds cars and bikes does well with a flake system and a polyaspartic topcoat. A basement or studio might be perfect for a metallic finish. A retail space with a sound slab might be best served by polishing the concrete itself. During the estimate we explain the tradeoffs honestly, including cost, cure time, look and maintenance, so you can choose the system that fits.

Fair, written estimates

Every quote spells out the prep, the repairs, the products, the number of coats and the expected schedule. There are no surprise charges for grinding or crack repair, because those steps are already included. If we find something unexpected once the old coating comes off, we stop and talk to you before doing any extra work.
