Why Fullerton ADU Builders Is Fontana’s Preferred Bathroom Remodeling Company
We’re not a generalist contractor dabbling in tile. We’re a Bathroom Remodeling specialist led by Glen Pacheco, and Fontana’s housing stock is exactly what we work on most: older tract homes and 1980s – 2000s infill subdivisions that each fail in predictable, decade-specific ways. Our crews know the southern Fontana blocks where cinderblock rear walls furred out with 1x strapping hide slow moisture damage, and they know the 92335 and 92336 subdivisions where builder-grade waterproofing behind tub surrounds starts leaking within a decade. Not many remodelers can walk into a home and tell you, by decade, what to expect behind the tile. We can.
Fontana homeowners call us because we quote honestly. When a single-panel electrical service can’t carry a new GFCI bathroom circuit, we don’t let you find out after the drywall is down. We inspect first, write allowances into the contract, and price every surprise before we touch it. Glen Pacheco insists on that process because he’s seen too many Fontana remodels blow their budget mid-project. It’s why our repeat business in 92337 and north of the 10 comes mostly from neighbors recommending neighbors.
Our Bathroom Remodeling Services in Fontana
Full Gut to Studs With Corrected Waterproofing
In Fontana’s 1980s – 2000s two-story homes, the most common failure we find is builder-grade waterproofing behind tub and shower surrounds. Re-tiling over it looks fine for about a season, then the grout darkens and the baseboards start swelling. We strip to studs, correct the assembly, and rebuild the wet wall properly. This is the difference between a remodel that lasts five years and one that lasts twenty.
Permit-Triggered Code Upgrades at Tear-Out
Opening up a 1950s or 1960s Fontana tract bathroom routinely turns up a single-panel electrical service with no capacity for a dedicated bathroom circuit. Fontana’s building department will require a GFCI-protected circuit, and we handle that upgrade as part of the remodel rather than as an afterthought. We also address ventilation requirements that older Fontana homes rarely meet, since hot Inland Empire summers and windowless interior baths create moisture problems that never dry out on their own.
Written Allowance and Change-Order Process
This is the part of the job that saves Fontana homeowners the most money and aggravation. Before we start, we walk the bathroom and identify likely discovery items based on the home’s era. Those items get written allowances in the contract with specific dollar ranges. If we open the wall and find damaged framing, the allowance covers it and you approve the exact number in writing before we continue. No surprise invoices at the end, no arguments about scope.
Shallow-Slab Framing and Plumbing Corrections
Fontana’s older tract homes sit on shallow slabs, which means bathroom drains and toilet flanges were often set in place decades ago with little room for adjustment. When we reconfigure a bathroom layout or move a fixture, we frequently have to correct slab-anchored plumbing and reinforce corroded or undersized framing against a shared cinderblock rear wall. We plan for this. An estimator who hasn’t done Fontana remodels these decades won’t.

Trusted Brands We Service in Fontana
We specify materials that hold up to Fontana’s climate, including James Hardie fiber cement backer and exterior products where applicable, plus waterproofing systems built for sustained heat and dry conditions. For homeowners planning a bathroom remodel alongside an ADU or garage conversion, we’re familiar with prefab systems from Abodu and Tuff Shed, which means your bathroom team and your ADU team can coordinate on one plan. We match the unit to the lot, not the other way around, and the same logic applies to your bathroom: we match the waterproofing and ventilation spec to your Fontana home’s age and exposure, not to a generic product lineup.
Common Bathroom Remodeling Problems We See in Fontana Homes
- Single-panel electrical services in 1950s – 60s tracts. A new GFCI bathroom circuit, humidistat fan, and lighting load frequently exceed what the original panel can carry. We include the service upgrade as a written allowance so it doesn’t blindside you.
- Failed waterproofing behind tub surrounds in 1980s – 2000s subdivisions. Homes in 92335 and 92336 were often built fast, with thin vapor protection behind tile. We strip to studs and rebuild the wet assembly correctly.
- Moisture creep into furred-out cinderblock walls. Older southern Fontana blocks share rear cinderblock walls with the neighbor’s yard. Over decades, condensation and slow leaks rot the drywall and 1x strapping behind the tile.
- Ventilation that can’t handle Fontana’s heat. Interior bathrooms without windows or with undersized fans stay damp through summer. We size exhaust systems for the square footage and the climate, not just for code minimums.

FAQs – Bathroom Remodeling in Fontana
Because opening up an original bathroom in a 1950s or 1960s Fontana tract routinely forces a single-panel electrical service upgrade and slab-anchored plumbing rework that can’t be seen from the finished side of the drywall. A quote that doesn’t include allowances for these discovery items is either uninformed or set up to change later. We inspect first and write those allowances into the contract so your initial quote reflects reality. Call (877) 801-4497 for an exact quote, and we’ll walk your specific home’s decade of construction with you.
Yes, in most older Fontana tract homes it does. The city requires GFCI-protected bathroom circuits, and a 1950s – 60s single-panel service often has no room for the additional breaker. We include this in our written allowances so it’s priced before demo begins, not discovered after your bathroom is down to studs. If you’d like to know whether your panel will require an upgrade, call (877) 801-4497 and we’ll check it during your free estimate.
In the 1980s – 2000s two-story subdivisions concentrated in 92335 and 92336, the failure is usually builder-grade waterproofing behind tub surrounds rather than electrical capacity. We strip to studs and correct the wet wall assembly. In the 1950s – 60s tracts, the failure is more likely electrical service capacity and shallow-slab plumbing. Your home’s address tells us which inspection scope to run. Call (877) 801-4497 and we’ll tell you what to expect for your specific Fontana neighborhood.
We price it as a written allowance before we start, get your signed approval for the exact number after we open the wall, and then continue work. No mid-project invoice without your sign-off. On a recent gut in one of the older southern Fontana tract blocks, our crew pulled the tub surround and found the cinderblock rear wall furred out with drywall on 1x strapping, no vapor barrier, and decades of moisture creep into the framing. We priced the reframe and vapor-correct assembly as written allowances, got the homeowner’s approval in writing, and continued demo. Final inspection passed with the new circuit, corrected framing, and a properly waterproofed wet wall.
Fontana’s summer temperatures above 100°F and strong Santa Ana winds mean we spec insulation and ventilation for sustained heat and dry conditions, not just code minimums. A windowless interior bath in Fontana needs a properly sized exhaust fan and moisture-resistant assemblies, or the damp air lingers and the grout fails early. We also coordinate with any ADU work you’re planning, since a detached unit with a bathroom on the rear of a Fontana lot faces the same wind and heat exposure. Call (877) 801-4497 and we’ll spec your remodel for Fontana’s climate, not a generic template.
