Styles & brands we work with







Home Renovation in West Hills
Home Renovation in West Hills means working with hillside pads, expansive soils, and homes built from the 1960s through the 1980s that often carry original structural and drainage systems never designed for today’s stormwater flows. A full home renovation here frequently starts with what you can’t see: foundation assessment, drainage correction, and wind-load verification. From there we handle kitchens, baths, flooring, windows, doors, and structural repairs under one written price.
Whole-Home Scope and Sequencing
We sequence work so you’re never living in a construction zone longer than necessary. Structural repairs and drainage come first, then rough-in plumbing and electrical, then finishes. For West Hills lots with terracing, we coordinate retaining wall work alongside foundation upgrades so one inspection covers both.
Windows and Doors That Meet Local Code
Window replacement in West Hills isn’t just about style. The Santa Susana Mountain foothills location triggers Exposure C wind requirements, meaning windows need an 85 mph wind-load rating. We install impact-rated products from CGI, CWS, and ES Windows, and we document the compliance so your permit closes clean and your insurance file is complete.
Home Remodeling Companies in West Hills

Home Remodeling Companies in West Hills aren’t all built the same. Many quote low by leaving out the structural and drainage work the city will require once plans are reviewed. Our written price includes what the code actually demands: wind-rated roof cladding, proper drainage tie-ins, and foundation work sized for expansive soils. That’s the difference between a quote that passes inspection the first time and one that generates change orders after demolition starts.
Bathroom Remodels on Hillside Slabs
Bathroom remodels on West Hills hillside slabs often reveal settling and moisture intrusion that a cosmetic update won’t fix. We inspect the subfloor and drainage before tiling. If we find movement, we address it under the same written price rather than springing it on you mid-project.
Finish Work With Specification-Grade Materials
We source cabinetry from KraftMaid and Wellborn, countertops from Cambria and Silestone, and fixtures from Kohler, Moen, and Toto. You get professional-grade materials without chasing down supply houses yourself. And every finish is covered by our written guarantee with clearly stated terms.
Trusted Brands We Service in West Hills
We install and service windows and doors from CGI, CWS, ES Windows, and ECO Window Systems across West Hills. These brands carry the wind-load ratings and impact resistance the local code requires. We keep common replacement parts stocked for fast turnaround when a window seal fails or a door needs adjustment, and our crews know the installation details each manufacturer demands for valid warranty coverage.

AfterCommon Home Remodeling Problems We See in West Hills Homes
- Undersized hillside drainage from the 1970s. Original systems south of Victory Boulevard were built for smaller stormwater flows. After the first heavy winter rain, we see slope erosion and slab settling that traces back to pipes that should have been replaced during a prior remodel.
- Unpermitted window replacements that fail wind tests. Cheaper jobs skip the 85 mph rating. During Santa Ana wind events these windows leak and whistle, and the homeowner discovers the permit was never pulled.
- Foundation settling on expansive soils. West Hills clay soils expand and contract with moisture. Homes built in the 1960s-80s often lack adequate footing depth, leading to cracks that cosmetic remodels can’t hide.
- Roof cladding not rated for Exposure C winds. Roof replacement quotes that don’t include 85 mph-rated materials won’t pass inspection. We see this most often on homes where a previous owner cut corners on a reroof.

FAQs About Home Remodeling in West Hills
West Hills requires roof cladding rated for 85 mph wind speeds under Exposure C due to its location in the Santa Susana Mountain foothills. That means impact-resistant shingles and continuous ridge vents, not a basic three-tab reroof. We document the rating on every permit submittal. Call (805) 309-3386 for an exact quote, estimates are free.
We pull the permit, schedule the inspection, and stand with the inspector on your job site. You don’t chase the city. For West Hills bathroom remodels, inspections typically include rough-in plumbing and electrical, waterproofing, and final. Our written price includes the permit fee and all inspection coordination.
Yes. We write the 85 mph-rated windows into the line-item quote from day one. A cheap quote omits them and hits you with a change order when the plan checker flags the deficiency. Our price already covers CGI, CWS, or ES Windows products that meet the local standard. Call (805) 309-3386 for a free written estimate.
Documented compliance gives your insurer evidence the work matches current code, which can help your premium or at least prevent a denied claim after a wind event. If you file a claim for storm damage and the insurer finds unpermitted windows that fail wind tests, coverage gets complicated. We provide the paperwork that proves compliance.
Check drainage first: downspouts tied to proper pipes, no ponding against the foundation, and visible slope away from the slab. Then confirm window and roof wind ratings appear in the final permit sign-off. On a recent project south of Victory Boulevard, our crew replaced a 1970s-era undersized drainage system that had caused recurring slope erosion and foundation undermining. We installed a modern perforated pipe system with proper slope and gravel bedding, then tied it to a new 85-mph-rated roof with continuous ridge vents and impact-resistant shingles, resolving both water intrusion and wind-uplift concerns. That’s what a complete punch list looks like.
