Fast, Reliable Bathroom Remodeling Across Belmont
Most Belmont bathroom remodels we look at need more than new tile. The homes here, especially the 1950s and 60s ranch-style and split-levels cut into the hillsides above El Camino Real, were built when a bathroom was meant to be small, dark, and purely functional. Homeowners in the 94002 zip code call us because a shower pan has been leaking into the subfloor, or the original cast iron tub is rusted through, or they’ve simply had enough of tiptoeing around a cramped layout that never worked for a growing family. A full bathroom remodel in Belmont typically runs $9,000 to $28,000 depending on scope, and we’ll put every dollar of that on paper before we touch a single stud.

Why Barrett & Sons Construction Is Belmont’s Preferred Bathroom Remodeling Company
We’re not a franchise dispatching strangers from three counties away. Tom Barrett founded this company in 1998, and he or his sons are on most Belmont job sites personally. When you call, a live person answers, not a voicemail box. You can look up Tom’s name, his license number, and his address before you ever sign a contract. That’s not a marketing tactic, it’s just how we’ve operated for over 29 years.
Belmont homeowners have told us the same story more times than we can count: a national company quoted one number over the phone, then showed up with a different bill and a list of “unforeseen conditions” that somehow weren’t in the contract. We do the opposite. Every scope, every allowance, every price change arrives as a written change order before work happens. The allowance that isn’t on paper is a surprise waiting for a date. If a permit is eligible for your remodel, we pull it, and we’re there when the inspector signs off. The permit inspector works for you, not for me. I like having him there.
Our Bathroom Remodeling team knows Belmont’s hillside geology well enough to spot the problems flatland contractors miss. When a bathroom sits over a settling cut-and-fill pad, cracked tile and a door that suddenly won’t latch aren’t just cosmetic annoyances. They’re signs of movement. We factor that into the plan from day one instead of discovering it halfway through your project.
Our Bathroom Remodeling Services in Belmont
Full Bathroom Remodeling
A gut renovation of a full bathroom in a Belmont ranch or split-level usually means moving walls, reworking plumbing, and rebuilding from the subfloor up. We tear out to the studs, fix any water damage we find, and rebuild with a focus on ventilation and water containment that matters more here where marine moisture and winter rain are part of life. Expect $9,000 to $28,000 for a typical full remodel in the 94002 area.

Walk-In Showers & Shower Remodeling
More Belmont homeowners are replacing tubs with low-curb or zero-threshold walk-in showers, especially those planning to age in place. On hillside homes, shower pan slope and waterproofing have to be done right the first time. A walk-in shower installation in Belmont typically runs $4,500 to $12,000. We use Schluter waterproofing systems and solid surface bases that won’t flex when the house settles an eighth of an inch in a wet winter.

Tub-to-Shower Conversion
Converting an existing tub to a shower is one of the smartest moves for a smaller five-foot bathroom in an older Belmont home up near Ralston Avenue or in the flatter Craftsman-era pockets by the Caltrain corridor. It opens floor space and makes the room feel twice its size. Expect $3,500 to $10,000 depending on whether we’re reusing existing plumbing locations or moving the drain line.

Vanities, Tile & Fixtures
Sometimes the bones are fine and the bathroom just looks tired. We install vanities from $800 to $3,000 including labor, and we’ll talk straight with you about which tile materials hold up in a damp Peninsula bathroom versus which ones look great for two years and then fail. We carry lines from Cambria and other brands you can actually research. A tile and fixture refresh in a Belmont guest bath often lands between $5,000 and $12,000 all in.

Common Bathroom Remodeling Problems We See in Belmont Homes
- Water intrusion from hillside drainage. Belmont’s clay-heavy Franciscan soils expand when saturated, and homes on the slope side often see moisture wicking through slab foundations or lower wall plates. We address drainage and waterproofing before we install finish materials so you’re not tearing out new tile in two years.
- Settling subfloors on cut-and-fill lots. When the fill portion of an engineered pad settles, bathroom floors slope and tile cracks. The fix is often a self-leveling underlayment or, in more serious cases, piering under the affected area. Flatland contractors miss this entirely.
- Undersized exhaust fans and mold. Bathrooms in 1950s and 60s Belmont homes were built before building codes required mechanical ventilation. Combined with summer fog, that means persistent mold on ceilings and around windows. We install properly sized Panasonic whisper fans that actually pull moisture out.
- Galvanized supply lines and cast iron drains. The original plumbing in many Belmont hillside homes is reaching end of life. If we’re in the walls anyway, we replace galv supply lines and corroded cast iron drain sections with PEX and ABS so we don’t bury a problem behind new tile.
Trusted Brands We Service in Belmont
We don’t install mystery materials off the back of a van. On bathroom remodels in Belmont, you’ll see names like Schluter for waterproofing, Delta and Moen for fixtures, and Cambria when quartz is the right call. We also stock common replacement parts locally so a failed cartridge or a cracked drain cover doesn’t leave your bathroom out of commission for a week. Because we’re already in Belmont regularly for our Roofing in Belmont work, our scheduling stays flexible enough to handle punch-list items quickly.
Pricing for Bathroom Remodeling in Belmont, CA
A full bathroom remodel in Belmont runs $9,000 to $28,000. A small bathroom with a tub-to-shower conversion typically lands between $5,000 and $12,000. Walk-in shower installations run $4,500 to $12,000, and vanity installation alone is $800 to $3,000. The biggest variables are whether you’re moving plumbing, whether we find hidden water damage or settling issues once walls are open, and whether your Belmont hillside lot triggers geotechnical review.

No trip charge inside the county, and a free second opinion on any written estimate you’ve received from another contractor. Call (877) 610-1318 to schedule yours.

Call (877) 610-1318 and a live person will get you on the calendar.
Yes. We work in the hillside neighborhoods above El Camino Real, the flatter Craftsman-era pockets near the Caltrain corridor, and the more recent developments toward the western edge of town. Every job gets the same written change order discipline and the same 90-Day Done Right Promise.
Every eligible job includes permits pulled and inspections signed. For most bathroom remodels in Belmont, that means plumbing and electrical rough-in inspections at minimum. If your hillside lot falls in a mapped landslide deposit zone and the city requires a soils report, we coordinate that too.
Belmont’s hillside lots add variables that flatter cities don’t have, like foundation settlement and drainage remediation, so some jobs here cost more than an identical remodel in Foster City. We also handle our Driveway & Pavers in Belmont services with the same attention to these site conditions. A full bathroom remodel in Belmont typically runs $9,000 to $28,000. We’ll give you an exact number in writing before you commit.
Every job comes with our 90-Day Done Right Promise written on the contract. If something isn’t right, Tom comes back and makes it right. One call. We’ve been operating this way since 1998, and we don’t hide behind fine print.
