About Concord Bathtub Resurfacing

Who we are, and the Concord we serve

Concord Bathtub Resurfacing started in 2017 with one van and a short list of repeat customers in the central Contra Costa suburbs. We have grown by referral since — a finished tub in one Clayton Valley ranch leads to the neighbor two doors down, then the cousin in Dana Estates. Nine years and more than 1,215 Concord fixtures later — an average of about 135 a year — we know the local housing stock by sight. We can usually tell you over the phone whether your tub is porcelain over cast iron or a one-piece fiberglass unit, because we have refinished roughly 656 tubs, 194 showers, 158 sinks, 109 countertops and 98 tile surrounds, the large majority within a couple of miles of downtown.

Everything we do stays inside Concord and the surrounding neighborhoods, which keeps the schedule tight and the trip charge at zero anywhere in town. We answer our own phone, we quote the job ourselves, and the technician who gives you a price is the one who sprays the coating.

Meet Azamat Franklin, lead refinisher

The business was founded and is run by Azamat Franklin, who has been spraying acrylic-urethane finishes across central Contra Costa County since 2017 and came up in the trade on a spray gun rather than a paint brush. He trained on two-part spray-applied coatings the way the chemistry actually demands — supplied-air respirator, HVLP gun, controlled overspray — and has logged more than 1,215 Concord fixtures in the years since, the large majority of them within a few miles of downtown Concord, with callbacks under his written warranty staying below 1.4%. His hands-on specialty is the work most crews would rather skip: heavy porcelain-over-cast-iron tubs, freestanding clawfoot and other vintage castings, fiberglass shells with floors gone soft, and the failed roll-on jobs that have to be stripped to bare substrate and started over.

Azamat still walks most quotes himself and personally sprays the jobs where the call is closer than a checklist — a clawfoot with lead-painted exterior, a cultured-marble vanity that has to be color-matched, a tub somebody coated from a hardware-store kit last spring that is already curling at the drain. "The coating is the five-minute part," he says. "Everything that decides whether you call me back in two years happens before the topcoat ever leaves the gun — how clean the surface really is, whether the etch took, whether I picked the right product for that substrate." He is just as quick to say no: "If a fiberglass floor crunches under my weight, or the iron has rusted clean through at the overflow, I'll tell you to replace it. I'd rather lose the job than warranty a finish over a problem a coating can't fix." When you phone in, you are usually talking to Azamat or to someone he trained on the same routine, etch for etch.

What we refinish

The core of the business is bathtubs — almond, harvest gold and avocado fixtures from the era when most of these neighborhoods went up, brought back to a clean white or a neutral your eye accepts again. From there the same coating system handles a lot of surfaces: full shower bases and surrounds, bathroom and kitchen sinks, laminate and cultured-marble countertops, and ceramic wall and floor tile. If it is porcelain, fiberglass, acrylic, cast iron, steel or cultured marble, we have a prep routine for it. The fixed prices on the pricing page cover each of these, and bundling two fixtures in one visit usually brings the total down.

How we hold our standards

A reglaze only lasts when the prep is honest. The coating is the easy part; adhesion is everything. On porcelain and cast iron we acid- or silane-etch the surface so it micro-roughens and the bonding primer can grip. On fiberglass and acrylic we scuff-sand and use an adhesion promoter instead, because acid does nothing to gelcoat. Then we repair chips, cracks and rust spots, lay the bonding primer, and spray an acrylic-urethane topcoat in even coats so it cures hard and smooth instead of going to orange peel. The full step-by-step is on the our process page, and we follow the same routine on every job whether it is a single sink or a tub-and-tile combo.

This is also why we get so many calls about peeling. A coating that lifts almost always skipped the etch or went down over a dirty surface, and that is the failure mode of hardware-store roll-on kits. We strip the old finish, clean down to the original substrate, re-etch and re-spray so the new coat bonds the way it should.

Licensed, insured, and warrantied in writing

Concord Bathtub Resurfacing is fully licensed and insured, and every job carries a written 5-year warranty on the finish. If a coating fails inside that window because of how we applied it, we come back and make it right at no charge — that is the whole point of putting it in writing. You should expect a real warranty and proof of insurance from anyone spraying chemicals inside your bathroom, and we hand both over before the work starts.

The Concord homes we work on

Concord is suburban Contra Costa, built mostly between the 1950s and the 1970s, and the bathrooms tell that story. The single most common problem we are called for is the 1950s–70s cast-iron tub with a rust ring under the faucet and a worn gray band in the bottom, often paired with the hard-water etching that central Contra Costa's mineral-heavy supply leaves on bare enamel. Out in Clayton Valley, Dana Estates and Sun Terrace the tubs are usually porcelain over heavy cast iron — sound fixtures with original color and the occasional rust streak under the faucet, ideal candidates for an acid etch and a long-lasting finish. The established streets of Ygnacio Valley and Holbrook run much the same. Newer construction around Northgate and parts of Ygnacio Valley leans on one-piece fiberglass tub-and-shower units, where the gelcoat goes chalky and the floor starts to flex; those get scuff-sanded and reinforced. Closer in, the walkable blocks near the Todos Santos plaza downtown mix older homes with apartments, and the rentals along the Monument Corridor turn over fast — a quick tub-and-sink reglaze gets a unit rent-ready in a day. We also cover Colony Park and Crossings, across ZIP codes 94518, 94519, 94520 and 94521. The full map is on the areas served page.

Reglaze instead of replace

The reason refinishing makes sense here comes down to math and color. A solid cast-iron tub is bonded to the wall tile around it; tearing it out means demolition, new surround tile, possible plumbing work, and hauling out a tub two people can barely lift. Reglazing leaves the fixture in place and gives you a fresh surface for a few hundred dollars instead of a few thousand — typically a 50 to 75 percent saving versus replacement, finished in a single 3-to-5-hour visit. The surface is ready to use 24 to 48 hours later. For most Concord homeowners updating a dated but serviceable bathroom, that is the difference between a Saturday and a multi-week remodel.
