Styles & brands we work with







General Contractor Services in West Hills
General Contractor Services in West Hills cover the full sequence of a remodel: demo, rough-in, structural work, trade coordination, drywall, finishes, and final inspection. A typical West Hills kitchen remodel runs $14,000 to $45,000. Bathrooms fall between $9,000 and $28,000. Here’s what that looks like on the ground.
Kitchen and Bath Remodels
Most West Hills projects start in the kitchen or the primary bath. Original 1950s and 60s ranches often hide galvanized plumbing and aluminum wiring behind the walls. We scope for that before demo, not after. A small kitchen remodel in West Hills lands around $9,000 to $20,000, while a small bathroom runs $5,000 to $12,000.

Room Additions and ADUs
Moving walls or adding square footage in West Hills means structural engineering, LADBS plan approval, and inspections at rough-in and final. A home addition in West Hills runs $45,000 to $130,000 depending on foundation, roofline, and utilities. An ADU starts around $90,000 and can reach $220,000. We pull permits on every one.

Construction Company in West Hills

Construction Company work in West Hills is heavier than what a handyman touches. Load-bearing walls, re-roofing, window replacement, garage conversions: these jobs need licensed trade coordination and passed inspections. A garage conversion in West Hills runs $30,000 to $80,000. A roof replacement lands between $8,000 and $20,000. Window replacement typically costs $4,500 to $15,000 depending on count and glass spec.
Garage Conversions and Structural Openings
Opening a wall between a galley kitchen and dining room on a 1960s ranch in the El Camino Real corridor near Fallbrook Avenue meant cutting a load-bearing wall and setting a permitted header. Our crew pulled the LADBS permit, walked the inspector through the rough-in before drywall closed, and signed off at final. That sequence matters. Skip it and you’re tearing out finished work later.
Deck and Exterior Builds
West Hills lots slope in places, and deck construction here often means pier footings on grade changes. We handle the structural layout, permit drawings, and build-out. Whether it’s a raised deck off a dining room or a ground-level platform for a paver patio, the work gets scoped and priced before we start.
Trusted Brands We Service in West Hills
We stock and install specification-grade materials from brands like KraftMaid, Cambria, Kohler, and Moen, which keeps West Hills jobs moving without waiting on parts from across the country. If you’ve been looking at factory-built or panelized options, we’re also familiar with systems from Abodu, Cover, and Dvele, and we can coordinate site work, foundations, and utility tie-ins for those builds. Having material and product knowledge local to West Hills means fewer delays and a tighter calendar.

AfterCommon General Contractor Problems We See in West Hills Homes
- Verbal walkthroughs instead of written scopes. A West Hills kitchen or bath quoted from a conversation, not a line-item scope, leaves allowances undefined and change orders open-ended. Before demo starts, you need the full bill in writing. We never move forward without one.
- Work covered before inspection. West Hills is under LADBS jurisdiction. Rough-in plumbing, electrical, and structural work must be inspected before drywall or tile closes it in. We schedule inspections at the right stage so the inspector sees what they need to see.
- Square-foot pricing without looking behind the walls. A 1962 rancher on Platt Avenue may still have original cast iron drain lines. A 1958 track home near Roscoe could hide aluminum branch wiring. Opening a wall is where pricing changes start. We open carefully and adjust in writing, not by surprise.
- Change orders that never get documented. If a West Hills homeowner wants to move a range line mid-remodel or upgrade tile after demo, the cost should be stated, agreed to, and added to the written contract. Undocumented changes create dispute. We write every change down before work resumes.

FAQs About General Contractor in West Hills
The City of Los Angeles through LADBS issues permits for West Hills. There is no separate West Hills or San Fernando Valley permit office. That means plan check, inspection scheduling, and sign-off all run through the city’s system, which is the biggest variable in any West Hills construction calendar. We handle the full permit process on your project. Call (803) 680-2547 for a free estimate and we’ll walk you through what your job requires.
Because the quote was verbal or the scope was thin. If allowances aren’t pinned down and change orders aren’t defined before demo, the final number drifts. Mason Remodeling writes a fixed price before any work starts, and every change you request gets added to the contract in writing before work resumes. That’s how you avoid the surprise bill. Call (803) 680-2547 for a written quote.
A general contractor manages the permit, the schedule, the licensed trades, the inspections, and the warranty. On a West Hills kitchen teardown, that means coordinating the plumber, electrician, framer, drywaller, tile setter, and countertop installer while keeping every inspection on the LADBS calendar. A handyman can patch and replace. A general contractor builds to code, passes inspections, and stands behind the work for 365 days. Call (803) 680-2547 to schedule your free estimate.
A typical West Hills bathroom remodel runs three to five weeks. A kitchen remodel typically runs six to ten weeks depending on scope, structural work, and how the LADBS inspection queue behaves. Additions and ADUs take longer, often four to eight months. We give you a written schedule with the written price, and we update it as inspections clear. Call (803) 680-2547 for a project-specific timeline.
Original cast iron plumbing, aluminum wiring, a soft subfloor, or an unexpectedly load-bearing wall. West Hills has thousands of homes built between 1955 and 1965, and those surprises are common. That’s why we inspect as we demo and put any necessary change in writing before continuing. You’ll never pay for work you didn’t approve. Call (803) 680-2547 for a free estimate and a written scope.
