Remodeling Company in West Hills, CA
West Hills remodeling work is different because the houses themselves are different: custom hillside builds from the 1960s through the 1980s on large, terraced lots, many sitting on expansive soils that shift with every wet winter and dry summer. We’re Mason Remodeling, and we handle general contracting, bathroom remodeling, and whole-home remodeling across West Hills with written pricing before any work starts and a 365-day guarantee on everything we complete. If you’re planning a remodel here, call (805) 309-3386 and we’ll walk you through what your specific home will actually need.
Why West Hills Homes Are Different

West Hills sits against the Santa Susana Mountains, and the homes reflect that geography. Many were custom-built from the 1960s to the 1980s on hillside pads with terracing that was engineered for a different era of stormwater. The area south of Victory Boulevard is a good example: we regularly see original 1970s hillside drainage systems that are undersized for today’s rainfall patterns, which leads to recurring slope erosion and, in some cases, foundation undermining. Homeowners often discover this only when a bathroom or kitchen remodel exposes a wall or slab and the real scope of the settling becomes visible.
The climate compounds it. West Hills gets intense summer heat followed by concentrated winter rain, and that thermal cycling stresses concrete flatwork, roofing, and exterior trim. Expansive soils swell when wet and shrink when dry, which is why retaining walls and foundation cracks are common call drivers here. When we plan a West Hills remodel, we look at drainage first, because a new bathroom or kitchen built on a pad that isn’t shedding water properly will fail at the edges before the paint is dry. This is a place where the lot matters as much as the floor plan.
Styles & brands we work with







Our Main West Hills Services
Most West Hills homeowners reach out to us for one of three things: a general contractor to manage a multi-trade job, a bathroom remodel, or a larger home remodel that touches structure. Each has its own dedicated page for West Hills, linked below.
General Contractor in West Hills
Acting as your General Contractor in West Hills means we coordinate the trades, the permits, the inspections, and the schedule on jobs where more than one system is changing. On a West Hills hillside lot that often means sequencing structural work before finish work, verifying the existing drainage and retaining walls before we open the walls. We deliver a written price before any tools are unpacked, and every crew member who arrives is identity-verified under the Threshold Standard, with their name and photo sent to you before the visit.

Bathroom Remodeling in West Hills
A Bathroom Remodeling in West Hills project on an older custom home often involves moving plumbing that was installed before modern code, which is where the surprises live. We plan for the reality of 1970s and 1980s framing, the occasional termite repair, and the waterproofing standard that West Hills’s seasonal rainfall demands on any exterior-adjacent wall. You’ll know who is coming, what it costs, and exactly what the guarantee covers, in writing, before we begin.

Home Remodeling in West Hills
Home Remodeling in West Hills covers larger scopes: opening walls, reconfiguring layouts, adding square footage, or bringing an entire floor of a 1960s custom home up to current standards. On hillside pads, that work must account for foundation condition, drainage, and the engineering realities of terracing. We price the whole project in writing up front, and our 365-Day Done Right Promise means if anything we built is not right within a year of completion, we make it right at no cost to you.

What pushes a West Hills job toward the top of these ranges is usually the lot: hillside access, retaining wall repairs, drainage corrections, and foundation work all add scope before finish materials even enter the conversation. Because we deliver a written price before any work begins, you’ll see exactly where the money goes, and that price does not grow on the final bill.
