Fast, Reliable Bathroom Remodeling Across Mayfair
Bathroom remodeling in Mayfair typically runs $9,000 – $28,000 for a full gut-and-replace, and a licensed contractor can usually start within two to three weeks once materials are ordered and permits are pulled. If you live in one of the post-WWII bungalows off San Antonio Street or around the Mayfair Community Center, call (936) 259-2607 and we’ll walk you through what your specific home needs. We know these 1940s – 1960s stucco-over-wood-frame houses well, and we know exactly what the San Jose building department will ask for before we touch a wall. That’s the difference between a quote that holds and one that falls apart on demo day.

- We give you a written price before work starts, and a written 365-Day Done Right Promise on every job.
- Trevor Nash leads every project, and a live person answers the phone 24/7, not a voicemail.
Why Penhallow Remodeling Is Mayfair’s Preferred Bathroom Remodeling Company
Mayfair homeowners call us because the neighborhood’s housing stock is predictable in the best and worst ways. The bungalows are charming and well-built by 1950s standards, but inside the walls we find the same things on nearly every job: galvanized supply lines at the end of their life, no shear panels, undersized framing, and waterproofing that failed quietly for years. We plan for it before we demo. That’s why our quotes from Mayfair customers tend to hold steady from the first number to the final invoice.
Every project is led by Trevor Nash, who walks each job personally before we commit to a number. Our crews are background-checked and arrive in uniform, and the people working in your home are the same people on record. When you call (936) 259-2607, a real person picks up, day or night. No phone tree, no callback promise that never comes.
We honor The Kingswell Way on every Mayfair job: say the price before the work, show up in the window we gave, and leave the place cleaner than we found it. That standard has been the backbone of the Kingswell family of companies since 2004, and each location, including ours, is independently owned and operated.
Bathroom Remodeling Contractor in Mayfair
A bathroom remodeling contractor in Mayfair does more than swap tile and fixtures. On these post-war bungalows, the job often becomes a structural and systems correction as soon as the inspector sees what’s behind the old tub surround. We plan for that from the first site visit. A full Bathroom Remodeling project in Mayfair typically runs $9,000 – $28,000, and the final number depends on what the walls reveal, what framing needs correction, and whether your home triggers the city’s seismic retrofit requirements.
What We Inspect Before Pricing
Before we give you a written number, we check the electrical panel, the water supply lines, the subfloor, and the wall framing. On a 1950s Mayfair home with a 60-amp panel, adding a new GFCI circuit for a modern bathroom may require a service upgrade. We price that into the quote as a written allowance with a line-item cost, not a vague “we’ll see when we get there.”
Code Upgrades as Part of the Job
When you pull a permit for structural work on a 1940s or 1960s Mayfair bungalow, San Jose’s building department frequently requires anchor bolts, cripple-wall bracing, and modern hold-downs that the original build never had. We handle that as part of the remodel, priced in writing before the first stud is removed. The bathroom is the visible project; the retrofit is the silent one that keeps the house standing in the next major quake.
Walk In Shower in Mayfair
A walk in shower in Mayfair usually replaces a cramped tub-and-shower combination in a home where the original bathroom was built for a smaller household. These 1950s bungalows commonly have 5-foot-wide bathrooms, and a curbless or low-curb walk-in shower opens the room visually and functionally. Walk-in shower installation in Mayfair runs $4,500 – $12,000, depending on whether we’re converting a tub, replacing an existing shower, or building new inside an expanded footprint. We convert tubs to showers starting around $3,500 on the low end.
Frameless Glass and Tile Work
We install frameless glass shower enclosures with exact-measure fabrication, and we use cement board substrate, the moisture-resistant layer behind your tile, rather than drywall in wet areas. On Mayfair homes with slab-on-grade foundations, we check the subfloor for seasonal heave cracks before tile goes down. Setting tile over a moving slab guarantees grout cracks, so we address the substrate first.
Shower Replacement and Seismic Considerations
Opening a wall for a shower rough-in on a Mayfair bungalow often exposes the same structural reality: no shear panels, undersized 2×4 framing, and supply lines that are nearly gone. When the inspector sees that, the scope changes. We had a job off Kammerer Avenue near the Mayfair Community Center where the client’s walk-in shower rough-in turned into a partial seismic retrofit that passed inspection first time, because we stopped, wrote a priced change order, and got approval before continuing. That’s how it should work.
Trusted Brands We Service in Mayfair
Mayfair homeowners get the same materials we’d put in any high-end remodel: Cambria and Silestone countertops, Kohler and Moen fixtures, and KraftMaid or Wellborn cabinetry when vanities are part of the job. We also keep common replacement parts accessible through our local supply channels, so a cracked shower valve or a failed cartridge during a remodel doesn’t stall the project for two weeks. Some Mayfair clients exploring a full restructure of their living space ask about the panelized construction approach used by companies like Mighty Buildings or Dvele; we can work within those parameters when the scope calls for it. The brands behind the work matter, because they’re part of the guarantee. Cambria quartz carries its own lifetime warranty alongside our 365-Day Done Right Promise, and we stand behind both in writing.
Common Bathroom Remodeling Problems We See in Mayfair Homes
- No shear panels and undersized framing: Walls opened on a post-war Mayfair bungalow reveal framing that wasn’t built for modern seismic or plumbing loads. A tile-and-fixture job becomes a load-bearing correction once the permit inspector sees it.
- Undersized electrical services: Original 60-amp to 100-amp panels and single water-service lines can’t support a modern bathroom’s GFCI circuits and fixture load. We price the panel upgrade as a written allowance, not a surprise.
- Failed waterproofing behind 1960s tile: Combined with seasonal slab heave on Mayfair’s expansive clay soils, failed waterproofing cracks shower pans and shifts subfloor. The remodel has to address the substrate, not just the finish.
- Galvanized supply lines at end of life: The original galvanized plumbing in these homes corrodes from the inside out. By the time you see the leak, the pipe is already compromised. We replace it while the wall is open.

FAQs About Bathroom Remodeling in Mayfair
Because Mayfair’s 1940s – 1960s stucco-over-wood-frame bungalows were built before California’s modern seismic codes. When you pull a permit for structural work, San Jose’s building department requires the contractor to add anchor bolts, cripple-wall bracing, and modern hold-downs that the original build never included. We inspect for this before pricing, write it into the contract as an allowance, and handle it as part of the remodel. Call (936) 259-2607 and we’ll tell you what your specific house needs.
We stop, write a change order with line-item pricing, get your signed approval, and only then continue. No verbal “this is going to cost more” surprises. On one Mayfair job, we found failing galvanized lines, undersized framing, and a 60-amp panel that couldn’t support the new circuit. The client approved a written change order and we finished with a first-time inspection pass.
Maybe, but probably not. A modern walk-in shower with proper GFCI protection and a dedicated circuit usually requires more capacity than a 60-amp panel can safely deliver. We’ll check your panel during the estimate, and if you need an upgrade, that cost goes into the written quote you see before work starts. No surprise line item at the end.
Full bathroom remodels in Mayfair run $9,000 – $28,000. Small bathrooms run $5,000 – $12,000. The price climbs when the walls reveal no shear panels, undersized framing, failing plumbing, or a panel that needs upgrading. We price those as written allowances in the contract, so you know the number before we start. Call (936) 259-2607 for an exact quote tailored to your house.
Yes, we pull all required permits for structural, plumbing, and electrical work through San Jose’s building department. We also schedule the inspections and make sure the job passes before we call it done. That’s how the 365-Day Done Right Promise stays enforceable: everything is documented, permitted, and inspected.
