Peeling coatings, rough slabs, and ADU conversions all start with proper surface prep. We grind, clean, and ready your concrete so every coating and floor system holds.
Concrete grinding in Berkeley uses diamond-tipped machines to shave the surface of your slab smooth and open, removing old coatings, stains, and uneven spots. Most garage or basement jobs take one day, with the floor ready for a new coating or installation immediately after.
If you are planning to add an epoxy coating, new tile, or polished finish, skipping this step is the single most common reason new surfaces peel, bubble, or fail within a year. Berkeley homes built before 1960 often have slabs that have collected multiple layers of coatings, old adhesives, and oil - all of which need to come off before anything new will bond properly. If you are considering concrete sealing as a next step, proper grinding is what makes that sealer last.
We walk you through the floor during the estimate and tell you exactly what it needs - no surprises on the day of the job.
If the painted or sealed surface on your floor is lifting in patches or coming up in sheets, the old coating has failed. Grinding removes the failed material down to bare concrete so the next coating has a clean, solid surface to bond to. This is one of the most common reasons Berkeley homeowners call - especially in older homes where multiple layers have built up over the years.
If you are converting a garage to a living space or rental unit - something many Berkeley homeowners are doing - the raw concrete slab almost certainly needs to be ground smooth first. Walk it in bare feet: if it feels rough or noticeably uneven in spots, tile, vinyl, or polished concrete will not sit right until the surface is leveled.
Decades of minor ground movement in Berkeley can cause sections of a concrete slab to shift, leaving one edge higher than the other. These raised lips are a trip hazard and will telegraph through any new flooring on top. Grinding knocks down those high spots and creates a safer, more even surface.
Oil stains from cars, rust marks from old appliances, or chemical discoloration soaked into the concrete cannot be scrubbed away - they are in the surface itself. Grinding removes the stained layer and exposes fresh concrete underneath. If you have tried cleaning the floor multiple times and the stains remain, surface prep is likely the only real solution.
We grind and prepare concrete surfaces for the full range of flooring systems we install. That includes prep before concrete sealing, epoxy coatings, polished concrete, tile, and decorative overlays. Every job uses industrial HEPA-filtered vacuums attached directly to the grinders to control dust - important in Berkeley neighborhoods where rooms in older bungalows connect quickly. We also remove old coatings, adhesives, and failed sealers before the grinding begins, so the machine is working on concrete, not buildup.
When grinding is done as prep for a new coating, we test the slab for moisture before we start - especially important in Berkeley's older homes and spaces close to grade. For garage conversions and ADU projects, we coordinate around permit timelines and other trades so the surface is ready exactly when it needs to be. If significant stripping or demolition is needed before grinding can begin, our concrete floor stripping and removal service handles that step first.
The right choice before any epoxy, polyaspartic, or sealer application - opens the surface profile so the coating bonds tightly and stays put.
The first pass in a full polished concrete system - establishes a flat, consistent surface before the progressive finer-grit polishing steps begin.
Suited to homeowners converting a garage or adding a rental unit - levels the raw slab before tile, vinyl, or other finish floors are installed.
Targeted grinding to knock down raised slab edges, humps, and uneven transitions that create safety hazards or cause flooring to fail at joints.
Berkeley has a large share of homes built between the 1920s and 1960s. Many of those garages, basements, and utility spaces have had multiple coatings, sealers, or adhesives applied over the decades. Before grinding can begin, a contractor needs to assess what is already on the surface - some older coatings require special handling during removal. Berkeley also sits near the Hayward Fault, and minor ground movement over decades leaves hairline cracks and uneven sections that need to be addressed before any new coating goes down. The American Concrete Institute and the Bay Area Air Quality Management District both set standards that shape how responsible contractors approach grinding work in this region.
Berkeley's coastal climate also means humidity levels are often higher than in inland California, especially during the rainy season from November through March. Moisture in the concrete itself can slow the curing of coatings applied after grinding - which is why we test slabs for moisture before applying anything. We serve homeowners throughout the East Bay, including Oakland and Richmond, where the same pre-war housing conditions and seasonal moisture patterns apply.
Reach out by phone or the contact form. We will ask a few basic questions - what the floor is used for now, what goes on top of it afterward, and what is currently on the surface. We aim to respond within one business day and schedule a walkthrough from there.
During the walkthrough, we look at the condition of the surface, check for cracks or uneven spots, and assess any existing coatings. In Berkeley, we also test the slab for moisture. You receive a written estimate that breaks down the scope, timeline, and what the floor will be ready for when we are done.
Before the crew arrives, you remove everything from the floor - furniture, stored items, vehicles. Close off the room from the rest of the house as much as possible. We set up industrial vacuum equipment directly on the grinders to capture dust as the work happens, keeping the rest of your home as clean as possible.
The crew works across the floor in overlapping passes. A standard garage or basement typically takes one full day. We walk the finished floor with you before packing up, and we give you clear written instructions on when the surface can be walked on, coated, or worked on - accounting for Berkeley's cooler, sometimes damp climate.

(341) 212-0767We use industrial HEPA vacuum systems attached directly to the grinders on every project. This matters in Berkeley's older bungalows and craftsman homes, where dust can travel quickly to connected rooms. The Bay Area Air Quality Management District has strict rules about airborne particulates, and we meet them.
We test every slab for moisture before quoting the job. Berkeley's coastal climate and older housing stock mean slabs hold more moisture than homeowners expect. Skipping this step is the most common reason a new coating fails within a season. We include moisture testing in the estimate so there are no surprises.
We have worked on concrete in Berkeley homes built across multiple decades - from the 1920s craftsmen in the Elmwood to mid-century slabs in the Flatlands. That range of experience means we know what to expect when we assess a surface, including how older coatings behave and what the grinding process will reveal.
You receive a written estimate that covers what is included, how long the job will take, and what the floor will be ready for when we are done. We verify the California Contractors State License Board license for every subcontractor we use - and you can confirm ours on the CSLB website before you hire.
Good surface preparation is not glamorous, but it is what determines whether the floor you invest in next year still looks good in five years. We treat the prep work as seriously as the finish coat, because without it, nothing else holds.
Protect a freshly prepared slab with a sealer that keeps moisture, oil, and grime from soaking back in.
