Fast, Reliable General Contractor Across West Covina
Most West Covina homeowners call a general contractor because the project has grown past the do-it-yourself stage, and they need one person who can keep subcontractors, permits, inspections, and the budget moving in the same direction. That is the job we do. A kitchen remodel in West Covina typically runs $14,000 to $45,000, a bathroom remodel $9,000 to $28,000, and a home addition $45,000 to $130,000. These are the real ranges we quote from, not placeholder numbers. Call (803) 680-2547 and we will walk your project and put a written price in front of you before any work starts.
We serve West Covina from the San Bernardino Freeway corridor down through the hills, and we know the difference between a 1950s ranch on a raised subfloor and a 1980s two-story near Shadow Oak Park. That matters when the wall comes open.
Why Mason Remodeling Is West Covina’s Preferred General Contractor Company
West Covina homeowners keep calling us back because we do the unglamorous thing first: we scope the job correctly before you spend anything. Every crew member who arrives at your door is background-checked, identity-verified, and introduced to you by name and photo before the visit. That is the Threshold Standard, and it applies on every job, no exceptions. Your first point of contact is a live person on the phone, 24 hours a day, seven days a week, not a call tree that dumps you into voicemail.
We have handled full gut remodels off Valinda Avenue, room additions near Cameron Park, and garage conversions in the neighborhoods around Delhaven Street. The feedback from West Covina customers is consistent: the written price matched the final bill, and the crew showed up when they said they would. Mason Remodeling has been doing this since 2004 as part of the Threshold Group family of home-service companies, and our 365-Day Done Right Promise means if anything is not right within a year of completion, we come back and fix it at no cost to you.

Remodeling Contractor in West Covina
A Remodeling Contractor in West Covina takes a room that has stopped working for its owners and rebuilds it, and the scope almost always runs deeper here than homeowners expect. West Covina’s housing stock was largely built in the 1950s through the 1970s, much of it on post-and-beam construction or raised subfloors with original cast-iron plumbing and 60-amp electrical panels. That means a “simple” kitchen or bathroom remodel frequently requires a panel upgrade and a cast-iron-to-ABS drain replacement before the finish work can even begin. A kitchen remodel in West Covina typically lands between $14,000 and $45,000, and the rough-in work is often the reason the final number ends up at the higher end.
Subfloor and Drain Reality Check
We opened a 1962 ranch-style kitchen off South Azusa Avenue near the West Covina Civic Center, and the homeowner had already picked KraftMaid cabinets and a Cambria counter. Demo revealed a failing cast-iron drain line and a 1958 electrical panel that could not carry the new induction range. We pulled permits through the City of West Covina Building Division, replaced the drain to ABS, upgraded the panel, and set the cabinets on a 3/4-inch subfloor patch that brought the floor back to level within 1/8 inch. The final inspection sign-off cleared both rough-in and finish, and the punch list closed in one walk.
What a Remodel Scope Actually Includes
Most West Covina remodels touch framing, electrical, plumbing, drywall, tile, and finish millwork. We carry the scope through inspections, coordinate the trades, and keep the schedule honest. A small bathroom remodel in West Covina runs $5,000 to $12,000, and a full bathroom remodel runs $9,000 to $28,000, depending on whether you move walls or fixtures.
Licensed General Contractor in West Covina
A Licensed General Contractor in West Covina is the one pulling the permits, scheduling the inspections, and standing behind the work when the project is finished. Mason Remodeling handles this for kitchens, bathrooms, whole-home remodels, room additions, ADU construction, and garage conversions throughout West Covina. A home addition in West Covina runs $45,000 to $130,000, an ADU $90,000 to $220,000, and a garage conversion $30,000 to $80,000. These are full-project figures that include the rough work, not just the pretty finish.
Permits and Inspection Sign-Off
Skipping City of West Covina permits on load-bearing wall removal or an ADU build may save a few weeks up front, but it fails inspection sign-off and costs double when you have to reopen finished walls. We pull permits before any structural work begins, and we do not leave the job until the final inspection is recorded. The written price we give you includes permit coordination, so there is no separate surprise line item.
Written Price Before Any Work Starts
Every Mason Remodeling project in West Covina gets a written price before a single tool is unpacked. Not a verbal estimate. Not an allowance that floats. A fixed dollar figure in a written scope of work, and that is the price unless you change the scope. If a repair or installation fails within the year, our 365-Day Done Right Promise covers the return visit at no charge. The terms of the written guarantee are stated plainly, including what is covered, what is excluded, and for how long.
Trusted Brands We Service in West Covina
We stock and install specification-grade materials our West Covina customers ask for by name. That includes cabinetry lines like KraftMaid and Wellborn, surface materials from Cambria, Silestone, and Caesarstone, and fixtures from Kohler, Moen, Toto, and Grohe. For homeowners considering a manufactured ADU, we have worked with units from Abodu and Cover, and we know how to prepare the foundation, utilities, and site so the factory-built module drops in clean and passes inspection. When you need a part or a replacement component, we source it locally for West Covina jobs and keep the turnaround tight.
Common General Contractor Problems We See in West Covina Homes
- Original cast-iron drains still in service. Homes built in the 1950s through 1970s often still have cast-iron drain lines under the slab or in the crawl space, and they fail from the inside out. A remodel scope that ignores this becomes an angry mid-project change order.
- 60-amp electrical panels that cannot carry a modern kitchen. Induction ranges, double ovens, and a dedicated microwave circuit easily exceed what a 1950s-era panel was built to handle, so the panel upgrade must be in the scope before cabinets go in.
- Skipped permits on structural work. We see homeowners who removed a load-bearing wall without a permit, then cannot sell the house or pass a refinance inspection. Reopening finished walls to fix an unpermitted change costs more than doing it right the first time.
- Allowance creep in the selection phase. When tile, fixtures, and cabinets are written as allowances instead of fixed dollar line items, the selection process quietly blows the budget and the draw schedule stops matching the money spent. We write fixed numbers into the scope of work.

FAQs About General Contractor in West Covina
No. Replacing cabinets and countertops in place, without moving plumbing, electrical, or walls, does not require a City of West Covina building permit. The moment you move a sink drain, add an outlet, or remove any wall, the permit becomes mandatory. Call (803) 680-2547 and we will tell you honestly whether your scope triggers permits or not.
Expect cast-iron drain replacement and likely an electrical panel upgrade. A 1961 West Covina home almost certainly still has original cast-iron under the slab, and a 60-amp panel will not support a modern bathroom fan, heated flooring, and GFCI outlets on separate circuits. Budget an additional $2,000 to $6,000 beyond the finish work, depending on access. Call (803) 680-2547 for an exact figure written into your scope.
You pay in phases as work is completed and inspected: typically a deposit, a rough-in draw, and a finish draw. Each draw should align with a specific milestone in the written scope of work, not a calendar date. We put the draw schedule in writing with your price, and you never pay for work that has not been done. Call (803) 680-2547 for a proposed draw schedule on your project.
Yes. Load-bearing wall removal is common in West Covina’s mid-century homes, and it requires an engineered beam, City of West Covina permits, and an inspection before the wall is covered. The structure must be calculated by a licensed engineer, and the beam size depends on the span and the roof load above. Call (803) 680-2547 and we will bring an engineer into the scope from day one.
Plan for 12 to 18 months from the first plan review to final inspection on a site-built ADU in West Covina, and roughly 9 to 14 months for a factory-built unit from Abodu or Cover once the site work and permits are approved. The City of West Covina plan review queue is the biggest variable nobody controls. Call (803) 680-2547 for a realistic schedule on your specific lot and floor plan.
