Fast, Reliable Bathroom Remodeling Across West Hills
A full bathroom remodel in West Hills typically costs $9,000 – $28,000, and the price moves most often when walls come open and reveal what 50-year-old hillside construction left behind: undersized drainage, cloth-jacketed wiring, and framing rot tied to slope moisture. Our crews know these homes because we work in them regularly. From the custom hillside lots south of Victory Boulevard to the newer renovations north of Roscoe, we handle the full job: tear-out, rough-in, permits, waterproofing, tile, fixtures, and final inspection. Call (805) 309-3386 to schedule a walk-through, and you’ll get a written price before any work begins. We serve all of West Hills, including the neighborhoods near Bell Canyon Road, Platt Avenue, and the commercial stretches along Sherman Way.
Why Mason Remodeling Co Thousand Oaks Is West Hills’s Preferred Bathroom Remodeling Company
West Hills homeowners tend to be specific about who walks through the door. That’s fair – a bathroom remodel means crew members in your home for two to six weeks. We operate under The Threshold Standard, which means every technician is background-checked and identity-verified before they arrive. You receive the name and photo of each crew member before the visit, and each person shows a photo ID badge at your door. Same process, every day, every job. No exceptions.
Our work in West Hills has taught us what these homes hide. The 1960s and 1970s custom builds south of Victory Boulevard often have original galvanized drain lines that are corroded at the slab, and the older hillside pads carry moisture from slope runoff into bathroom framing in ways a tract home in the flats never would. We quote with those realities in mind from the first visit. That’s why our written pricing includes allowances for the predictable surprises, so you’re not staring at a change order that doubles the job without understanding why. When we open a wall and find rot or outdated wiring, we show you what we found, explain what code requires, and get your written approval before any additional work starts. That’s the Mason Remodeling Co Thousand Oaks way – no verbal estimates that grow, no surprises on the final invoice.
Styles & brands we work with
Bathroom Remodeling Contractor in West Hills
A bathroom remodeling contractor in West Hills does far more than swap a vanity and retile a shower. The job starts with what’s behind the walls: the condition of subfloor, drain lines, vent stacks, and the framing that’s been sitting against original 1970s waterproofing for four decades. In this climate – hot, dry summers followed by occasional heavy winter rain – tile and grout expand and contract, and any hairline crack in an old shower pan becomes a slow leak into a hillside subfloor. A complete remodel in West Hills typically runs $9,000 – $28,000 depending on size, fixture grade, and what rough-in work the permit inspection requires.
Permits and Code Upgrades in Older West Hills Homes
Opening walls in a 1960s or 1970s West Hills bathroom usually triggers electrical and ventilation requirements that weren’t code when the house was built. Ground-fault protection, proper exhaust fan CFM ratings, and sometimes circuit rewiring become part of the job. We pull permits on every project that requires them, and we walk you through what each upgrade costs in writing before the inspector walks in.
Hidden Damage From Original Construction
The original hillside drainage systems south of Victory Boulevard were designed for a different era’s stormwater volume. When we open a bathroom wall in one of these homes, we often find moisture damage that has nothing to do with the bathroom itself – water migrating from slope runoff, pooling against a foundation wall, and wicking into the mudsill and bathroom framing. We bring in our inspector before closing walls, and we price the repair in a written change order. You approve it. Then we fix it.
Walk In Shower in West Hills
A walk-in shower in West Hills is a practical upgrade for the same reason it’s a beautiful one: these homes have aging original tubs, and a curbless or low-profile shower changes how a bathroom functions for everyone in the household. Walk-in shower installation in West Hills runs $4,500 – $12,000, and the final number depends on whether we’re converting an existing tub footprint or reworking the floor drain and waterproofing in a larger space.
Waterproofing That Handles Hillside Conditions
We use Schluter strip – the metal trim that seals the edge where tile meets flooring – and full-wall waterproofing membranes on every walk-in shower we build in West Hills. The climate here demands it. Thermal expansion from those intense summer heat waves, followed by cold rainy-season nights, stresses any seam in a tile assembly. A properly waterproofed shower pan and membrane system is the difference between a 10-year shower and a problem inside five.
What a Tub-to-Shower Conversion Involves
Converting a tub to a walk-in shower in West Hills usually means removing the old cast-iron or fiberglass tub, relocating or upsizing the drain to 2 inches, adding blocking for grab bars if you want them, and then building a waterproofed shower on the existing footprint. In older West Hills homes, this is also the moment we discover whether the original drain line is adequate. In many of the 1970s custom builds, it isn’t – and we’ll show you exactly what we found and what the fix costs before we proceed.
Trusted Brands We Service in West Hills
We work with specification-grade products from KraftMaid, James Hardie, and other vetted professional lines, so the materials going into your West Hills bathroom are built to perform in this climate. When you choose cabinetry from KraftMaid, you know the dimensioned casework and drawer hardware have been tested far beyond what a box-store vanity gets. James Hardie backer board holds up to the moisture swings we see in hillside homes. We stock common parts locally so turnaround on replacement hardware or a broken fixture is measured in days, not weeks. Our team will walk you through each material option, explain what it costs, and include the line item in your written estimate.

AfterCommon Bathroom Remodeling Problems We See in West Hills Homes
- Undersized 1970s drainage pipes. The original pipe in many older West Hills bathrooms is 1.5 inches, but modern fixtures and shower valves need a 2-inch drain to flow correctly. This means opening the slab or wall and replacing a section of pipe – not a fun surprise, but one we price in an allowance so it’s not a shock.
- Cloth-jacketed electrical wiring. Homes built in West Hills before about 1980 often still have the original cloth-insulated wire. Once a wall is open, code requires us to address it. That’s an upgrade you’ll be glad you made, but you should see the line item before the electrician starts.
- Failed waterproofing behind cosmetic updates. We’ve pulled out plenty of tile that looked fine on the surface and found the drywall behind it softened and the framing rotted at the base. On a hillside pad, that moisture often starts outside the house and migrates in.
- Rot at the wall base from old shower pans. A cracked or corroded shower pan leaks for years before anyone sees it. By the time we open the wall, the damage is done. We replace the framing, install a modern waterproofed pan, and document the repair for your records.

FAQs About Bathroom Remodeling in West Hills
Because many West Hills homes south of Victory Boulevard sit on hillside pads with original 1970s drainage systems that are undersized for today’s stormwater flows. When a bathroom wall comes open and we see moisture at the base, we’ll ask about the slope behind the house and whether water is pooling against the foundation. It’s not uncommon for a bathroom job to reveal a drainage issue that needs addressing before we close walls. If that happens, you get a written change order with a specific price and clear explanation. No work proceeds without your approval. Call (805) 309-3386 for an exact quote.
We inspect before we close walls, and we bring in our electrical inspector while the wall cavity is open. Outdated wiring – often cloth-jacketed in West Hills homes from that era – gets documented, photographed, and priced in a written change order. We explain what code requires and what each upgrade costs before any electrical work begins. You approve the scope and the price, then we proceed. Call (805) 309-3386 if you want to talk through what this might mean for your specific house.
Expect ground-fault circuit interrupter protection on bathroom outlets, a properly rated exhaust fan vented to the outside, and in many older West Hills homes, replacement of undersized drain lines to meet current code. Each of these is a line item in your written estimate before work starts. If a permit inspection uncovers something else, we handle it the same way: explain, price, get your approval in writing, then fix it. Call (805) 309-3386 for a project-specific breakdown.
Yes. An allowance is a specific dollar amount we build into your written estimate to cover work that can only be confirmed once walls are open – things like drain line replacement, subfloor repair, or framing corrections. In West Hills, we write allowances for the predictable surprises in older hillside homes. Any unused allowance gets credited back to you. Any additional scope gets its own written change order before we proceed. You never pay for something we didn’t show you first. Call (805) 309-3386 for a free estimate.
Yes, often it can – if the moisture is entering the bathroom from failed shower waterproofing or a leaking pan, fixing that stops the damage at the source. If the moisture is coming from slope runoff against the foundation wall, the bathroom remodel is the moment to address it, because we’re already opening the wall and can repair framing, install proper drainage, and waterproof the exterior side of the wall. We recently remodeled a primary bathroom in a custom 1970s hillside home south of Victory Boulevard. When we opened the wall behind the original tub, the subfloor showed rot from a failed shower pan and the rough-in wiring was cloth-jacketed. We brought in our inspector before closing walls, upgraded the drain to current code, and wrote a change order for the framing repair before proceeding – final walkthrough had zero surprises. Call (805) 309-3386 to schedule a walk-through.
