Remodeling Company in Winnetka, CA
Mason Remodeling handles whole-home renovations, kitchen and bath work, and general contracting across Winnetka, CA. Most of the homes we walk into here were built between 1948 and 1965, and they’re reaching an age where plumbing, electrical, and roofing failures tend to arrive at the same time. That’s what makes Winnetka work different from remodeling in newer parts of the Valley: the job usually starts with infrastructure, not finishes. Call (831) 290-6866 and we’ll give you a written price before any tool comes off the truck.
Why Winnetka Homes Are Different
Winnetka is almost entirely single-story, single-family, wood-frame construction with stucco exteriors and composition shingle roofs. Those homes have now been standing for 60 to 75 years, and the original systems are giving out in predictable ways. We regularly open walls and find galvanized steel supply lines corroded from the inside, and 100-amp electrical panels that cannot carry the load of a modern kitchen, let alone an ADU. Original single-pane aluminum windows show up on nearly every job, and most of them no longer meet California energy code.
The climate is hard on these houses. Summer temperatures over 100°F bake composition shingles until they crack and curl, and the stucco moves enough to develop hairline cracks. When winter rains arrive, they find those cracks. The flat, expansive clay soil under much of Winnetka swells and shrinks with moisture, which is why some older raised foundations show signs of movement that newer tract neighborhoods never see. A remodel here is rarely cosmetic once you look behind the drywall.
One thing that works in homeowners’ favor: lot sizes in Winnetka often run 7,500 square feet or more, and most neighborhoods have no HOA. That combination makes ADU construction and garage conversion more practical here than in almost any other part of the west Valley. We’ll get into that more on the service pages linked below.
Styles & brands we work with
Our Main Winnetka Services
We provide three core services in Winnetka, and each has its own page with pricing, process, and local details. The two that drive the most calls are whole-home remodels and bathroom work, but general contracting ties them all together for homeowners who are sequencing multiple projects.
General Contractor in Winnetka
Acting as your General Contractor in Winnetka means we coordinate every trade, pull permits, and keep the job moving when surprises surface, which they will in a 1950s house. We sequence work so you’re not living without a kitchen while a plumber waits on an electrician. On Winnetka jobs, that often starts with upgrading service panels and replacing corroded supply lines before any finish work begins. We also check attic-mounted horizontal furnaces for asbestos-containing duct wrap before demolition kicks off, because that’s a common condition in this housing stock and it changes the order of operations.
Bathroom Remodeling in Winnetka
Our Bathroom Remodeling in Winnetka work typically involves gutting a 1950s or 1960s bathroom down to the studs and rebuilding it around modern waterproofing. In Winnetka, we frequently find cast-iron drain lines that have thinned or cracked underground, and they have to be addressed before a new shower pan goes in. We use Schluter waterproofing systems on tub surrounds and walk-in showers, because they hold up to the temperature swings these stucco homes experience. Expect us to talk about what’s behind the tile as much as what goes on top of it.
Home Remodeling in Winnetka
A Home Remodeling in Winnetka project usually means opening up a ranch floor plan, replacing windows, re-roofing, and bringing electrical and plumbing up to code, often in one coordinated effort. The large lots here also make room additions and ADUs more feasible, which is why a growing share of our Winnetka work involves adding square footage rather than just reconfiguring it. Every project starts with a written price, and every project ends with a written guarantee that covers the work for 365 days from completion. If something isn’t right, we come back and make it right at no charge.

What pushes a Winnetka job toward the top of these ranges is usually the age of the house. Rewiring a 100-amp panel, replacing galvanized supply lines, or repairing a raised foundation adds cost that newer neighborhoods don’t carry. Whatever the number ends up being, you’ll have it in writing before work starts, and it won’t change unless you change the scope.

FAQs About Remodeling Company in Winnetka
Most Winnetka projects can be scheduled within two to four weeks, depending on permit processing with the Los Angeles Department of Building and Safety. Bigger jobs, like ADU construction, may take longer because plan review adds time. Call (831) 290-6866 and we’ll give you a realistic start window for your specific project.
Yes, for any work that changes structure, plumbing, electrical, or square footage. Winnetka falls under Los Angeles city permitting rules, and we pull every permit ourselves as part of the job. Work done without permits can stall a future sale and may not pass inspection when it’s finally reviewed.
