Why Orange ADU Builders Is Los Serranos’s Preferred Bathroom Remodeling Company
We’re a kitchen and bath remodel company that cut its teeth on ADU construction, which means framing, waterproofing, and permit inspections are daily work for us, not an afterthought. Los Serranos homeowners hire us because we write allowances into every contract for the things this area’s housing stock actually reveals: aluminum wiring, notched framing, and subfloor rot from Carbon Canyon moisture wicking. Nelson Ybarra, our owner, has built the company around written change orders and county-inspected repairs. Nothing gets done in your wall without a signed price in front of you first.
Our Los Serranos customers appreciate that we don’t hand off work to a rotating cast of subs. The same crew that demos your shower pan manages the permit inspection and the tile work. We’re familiar with San Bernardino County’s building code triggers because we’ve pulled bathroom permits in this unincorporated community many times. When a hall bath near English Creek needs framing sistering before inspection, we’ve already priced that scenario into the allowance so it’s not a shock at week three.
Response time to Los Serranos is typically same-week for estimates. We schedule around your workday, and our project manager walks the site with you before writing the quote. That walk-through is where we look for exactly the problems this page explains, so the first number we give you is grounded in your actual house, not a generic spreadsheet.
Our Bathroom Remodeling Services in Los Serranos
Most Los Serranos bathroom remodels fall into one of four scopes. Each has different cost drivers in this community, so we break them out honestly below.
Full Gut Remodel with Permit-Triggered Code Upgrades
This is the most common project in Los Serranos. A 1978 hall bath off the primary bedroom gets taken down to studs, at which point San Bernardino County’s building inspector requires ventilation, GFCI placement, and framing to meet current code, not 1978 code. We handle the permit from day one and write the code upgrades into the base quote, not as a surprise add-on. Expect $22,000 – $42,000 depending on fixture grade and whether we’re moving plumbing.
Waterproofing and Shower Pan Replacement
Sloping lots toward Carbon Canyon mean groundwater and slab moisture don’t drain away from the foundation, they sit against it. We regularly find shower pans that failed years ago and quietly rotted the subfloor beneath. In Los Serranos, waterproofing is not optional or cosmetic. We use membrane systems and sloped mortar beds built for this exact failure mode, and we photograph every layer before tile goes down, so the county inspector and you both see what’s under the finished floor.
Framing Repair and Sistering for Older Tract Homes
1970s and 1980s tract homes in the 91709 area were framed with 2×4 walls, and previous remodels often notched those studs to route drain lines. Open that wall today and the county inspector will flag it. We sister new full-depth framing alongside the damaged member, which gives the wall structural integrity and lets the shower valve mount properly. This repair typically adds $1,200 – $2,800 to a Los Serranos remodel, depending on how many studs are compromised.
Floor-to-Ceiling Finish Work and Fixture Upgrades
Once the structure is sound and the waterproofing is in, we handle the part homeowners actually see: tile, vanities, glass enclosures, lighting, and trim. Many Los Serranos homes still have the original almond-colored fiberglass tub surrounds and single-basin vanities. We source period-appropriate fixtures when you want to keep the 1980s character, or we go fully modern with larger-format tile and curbless showers. The choice is yours, but the prep work underneath is always code-compliant.

Common Bathroom Remodeling Problems We See in Los Serranos Homes
- Aluminum wiring in 1970s tract homes. Los Serranos homes built between 1970 and 1977 often used aluminum branch circuits. Once the wall is open, San Bernardino County requires copper pigtails at every splice and a county inspection before we close up. This costs $800 – $1,500 for a typical bathroom and is an unallowed expense in many fixed bids.
- Slab and subfloor moisture from Carbon Canyon slopes. Homes on the sloping ground toward English Creek and Carbon Canyon see moisture wicking up through slab foundations. Failed waterproofing shows up as soft framing and subfloor rot under tile, not just a leaky pan. We inspect the subfloor before quoting so the first number reflects what’s actually there.
- Notched 2×4 framing from earlier remodels. A previous vanity relocation or drain reroute often left studs notched or drilled through. County framing inspection will fail that wall. Sistering is required, and we price it per stud so the allowance is transparent.
- Original tile and fixture matching. Many Los Serranos homeowners want to keep the 1980s hall bath look but the original almond or harvest gold tile is discontinued. We work with local salvage and reproduction suppliers to match glaze color and sizing, or we source current-period alternatives that don’t look jarring next to the original hall bath.

FAQs – Bathroom Remodeling in Los Serranos
Yes, a bathroom remodel in unincorporated Los Serranos requires a San Bernardino County building permit whenever plumbing or electrical is moved or walls are opened. The permit triggers county-level code upgrades for ventilation, GFCI placement, and framing integrity, which often means bringing a 1970s bathroom up to current standards. Expect those upgrades to add $1,500 – $3,500 to your project. Call (877) 265-5812 for an exact quote on your scope.
The biggest hidden cost is aluminum branch wiring behind the walls. Homes built in the 1970s here used aluminum circuits, and once the wall is open, San Bernardino County requires copper pigtail connections and an inspection before drywall goes back up. That typically runs $800 – $1,500. We include a wiring allowance in every Los Serranos quote so that cost is documented before demolition starts.
Homes on the sloping ground toward Carbon Canyon and English Creek experience slab moisture that wicks upward through bathroom floors. Failed waterproofing in this area shows up as soft framing and subfloor rot beneath the tile, not just a damp shower pan. We inspect the subfloor before writing your quote, and our waterproofing details are built for this specific moisture pattern in Los Serranos.
Yes, we source period-appropriate tile and fixtures from local salvage and reproduction suppliers when homeowners want to preserve the original 1970s or 1980s look. We can match glaze color and sizing for most original Los Serranos tract home finishes. If the original is discontinued, we’ll show you current alternatives that sit comfortably alongside the rest of the house.
We pause work, document the condition, write a change order with the exact repair and price, and get your signature before touching the affected area. On a 1978 tract home near English Creek, our crew found aluminum wiring spliced to a newer GFCI plus notched framing behind a hall bath wall. We wrote the copper pigtail and sistering into a signed change order before repairing it, then finished the tile the next week. That’s how every surprise is handled: documented, priced, approved, and then fixed.
