Fast, Reliable General Contractor Across Winnetka

Most Winnetka homeowners calling a General Contractor for the first time are staring at a 1950s ranch with three problems hitting at once: a failing composition roof, a 100-amp electrical panel that can’t handle modern loads, and cast-iron drain lines that have been corroding for sixty years. That’s the reality of our post-war housing stock, and it’s work we know well. Mason Remodeling Co Woodland Hills handles whole-home remodels, kitchen and bath renovations, room additions, and ADU construction across Winnetka. Call (831) 290-6866 for a written estimate before any work begins.

Why Mason Remodeling Co Woodland Hills Is Winnetka’s Preferred General Contractor Company

A finished backyard cottage with a small covered porch

Winnetka homeowners tell us the same thing again and again: they want to know exactly who is walking through the door. The Threshold Standard, named for the process every Mason Remodeling technician follows, means you get the crew member’s name and photo before the visit, and a photo ID badge shown at the door. No exceptions. Isaac Pruett leads our team, and we’ve been doing this work since 2004 as part of the Threshold Group family of home-service companies.

Response time to Winnetka matters because so many of the homes here are reaching the same age at the same time. When a 1958 ranch on Oso Avenue needs a roof replacement and the kitchen remodel below it has water damage, you don’t want a contractor who has to look up where Saticoy Street is. Our crews are already working in Winnetka on projects similar to yours, and scheduling reflects that. A written price is delivered before any tool is unpacked, on every project, every time.

Remodeling Contractor in Winnetka

A Remodeling Contractor in Winnetka handles what these 1950s and 60s ranchers need most: kitchens and bathrooms that were built for a different era, plus the structural updates that come due around year sixty. On Saticoy Street and Vanowen Street, we regularly open walls and find galvanized steel supply lines so corroded they can’t be reused. The work involves plumbing replacement, electrical panel upgrades, drywall, tile, and finishes, most often as part of a larger renovation. Homeowners call us when a kitchen remodel is needed and the house hasn’t been touched since the original build.

Kitchen and Bath Remodels on Post-War Ranches

Winnetka kitchens from the 1950s are typically 60 to 100 square feet with a single window over the sink. A full kitchen remodel in Winnetka runs $14,000 to $45,000, with smaller kitchens in the $9,000 to $20,000 range. Bathrooms from the same era share one 5-foot tub and a floor-mounted cast iron drain that has likely been seeping for years. Bathroom remodels here range from $9,000 to $28,000 for a full gut, and $5,000 to $12,000 for smaller baths.

What We Find Behind Winnetka’s Stucco Walls

Original horizontal furnaces in the attic are still present in many Winnetka homes built before 1960, and any remodel touching the ceiling or attic means checking for asbestos-containing duct wrap before work proceeds. This is a known local issue, and we test before we cut. It adds a step but prevents a stop-work situation mid-project.

Licensed General Contractor in Winnetka

A single-story rear room addition with tall windows and a new patio

A Licensed General Contractor in Winnetka is the person who pulls permits, schedules inspections, and makes sure the work passes on the first look. For additions and ADUs, that means understanding Los Angeles Department of Building and Safety zoning rules as they apply to Winnetka’s 7,500-plus square foot lots with no HOA oversight. The city reviews what gets built, and we file the submittal packet ourselves: elevation drawings, material samples, and site plans. Home additions in Winnetka run $45,000 to $130,000. ADU construction, from plans to final inspection, runs $90,000 to $220,000. Garage conversions run $30,000 to $80,000.

Permits and Architectural Review Done Right

Because Winnetka has no HOA restrictions, architectural review is a city function, not a neighborhood committee. That means approval hinges on matching the existing 1950s single-story ranch massing, stucco finish, and composition roof, not on covenants. We know what the reviewers look for on Oso, Saticoy, and Vanowen, and we build the submittal packet to pass plan check the first time. Skipping this step, or assuming a garage conversion doesn’t require plans, leads to stop-work orders and change orders that add weeks to the calendar.

Warranty and Guarantee in Plain Terms

The 365-Day Done Right Promise means if the work is not right within a year of completion, we make it right at no cost. It covers general contracting, bathroom remodeling, and whole-home remodels. You get a written guarantee on every project with coverage terms stated plainly, including what is covered and what is excluded, and for how long. A free return visit is provided at no charge if a repair or installation fails.

Trusted Brands We Service in Winnetka

For Winnetka remodels, we specify materials from brands that hold up to San Fernando Valley heat and the specific demands of post-war construction. James Hardie siding and trim resist the dry-summer cracking that plagues original 1950s stucco, while KraftMaid and Wellborn cabinetry give Winnetka kitchens the storage and proportion these compact footprints lack. We stock common replacement parts locally for faster turnaround, which matters mid-project when a cabinet hinge or trim profile needs to match.

Common General Contractor Problems We See in Winnetka Homes

  • Failing original electrical panels. Many Winnetka homes still run on 100-amp service from the 1950s. A kitchen remodel with modern appliances almost always requires a panel upgrade to 200 amps, and the city won’t sign off on new circuits pulled into an undersized panel.
  • Corroded galvanized supply lines. Galvanized steel pipes from the original build are at or past their service life. We routinely replace them with copper or PEX during any bathroom or kitchen remodel, because patching a sixty-year-old galvanized line is a temporary fix.
  • Attic furnace and duct wrap surprises. Homes built before 1960 often have a horizontal furnace in the attic, and the duct wrap may contain asbestos. Any remodel touching the ceiling, lighting, or attic insulation requires testing first, which we handle as part of the pre-construction inspection.
  • Expansive clay soil and foundation movement. Winnetka’s flat lots sit on clay that swells with winter rain and shrinks in summer heat. This causes the stucco cracking and door misalignment we see regularly, and it’s why we check foundation condition before framing any addition.
