Fast, Reliable General Contractor Across Alhambra
If you’re planning a kitchen remodel, bathroom renovation, or room addition in Alhambra, the first question is usually the same: what will this actually cost, and who is coming into my home? A typical kitchen remodel in Alhambra runs $14,000 – $45,000, a bathroom remodel $9,000 – $28,000, and a home addition $45,000 – $130,000. Mason Remodeling delivers a written price before any work starts, and every crew member who arrives at your door is background-checked, uniformed, and introduced by name and photo before the visit. Call (803) 680-2547 to schedule a free estimate.
We know the housing stock here well. Alhambra is filled with mid-century tract homes built in the 1940s and 1950s, and those houses come with real planning constraints that newer San Gabriel Valley construction doesn’t face. Older 100-amp electrical panels, minimal wall space in galley kitchens, and load-bearing walls that don’t look load-bearing all affect how a project gets scoped and priced. Getting those details right before you sign a contract is the difference between a job that closes clean and one that drifts into change orders.
Key Takeaways

Why Mason Remodeling Is Alhambra’s Preferred General Contractor Company
Alhambra homeowners call us because our process removes the two biggest anxieties in a remodel: not knowing who is showing up, and not knowing what the final bill will be. Every technician is background-checked and identity-verified under what we call the Threshold Standard. When we schedule work in Alhambra, you receive the crew member’s name and photo before they arrive, and they show a photo ID badge at the door. That matters whether you’re home alone, have young kids, or just don’t want to open your door to a stranger without knowing exactly who he or she is.
Our reputation in Alhambra is built on written pricing and a written guarantee on every project, including General Contractor work, bathroom remodels, and whole-home remodels. The 365-Day Done Right Promise means if work isn’t right within a year of completion, we make it right at no cost to you. No dispute process, no fine print runaround. A live person answers our phone 24 hours a day, 7 days a week, including weekends and holidays. Call (803) 680-2547 and you’ll talk to a person, not a voicemail tree.
Founded in 2004 as part of the Threshold Group family of home-service companies, Mason Remodeling has spent two decades working in homes like the ones that line the streets around Almansor Park, Granada Park, and the neighborhoods south of Main Street. We understand what an unpermitted wall removal does to a resale, what knob-and-tube wiring looks like when you open a 1950s ceiling, and what a realistic timeline looks like when you’re pulling Alhambra building permits.
Licensed General Contractor in Alhambra

A Licensed General Contractor in Alhambra is the contractor of record who pulls permits, coordinates subcontractors, schedules inspections, and carries the project from demolition to final sign-off. When you hire Mason Remodeling for a kitchen or bath remodel, we handle the entire job: demolition, framing, electrical, plumbing, drywall, tile, cabinetry, countertops, and finish work. You don’t juggle separate electricians and plumbers. You get one written scope of work, one written price, and one point of contact from start to finish.
Alhambra’s building department requires permits for wall removals, electrical rough-in, plumbing changes, and any structural work. We pull those permits for you and schedule the inspections. In older Alhambra homes, a simple wall removal can turn into an engineering question if the wall is load-bearing, and that’s the kind of thing you want caught during planning, not after demo. We’d rather spend an extra hour in plan check than hand you a change order mid-project.
Kitchen and Bath Remodels
Alhambra kitchens in 1940s and 1950s tract homes are often compact, with limited wall space for cabinet runs and appliance placement. Before we price anything, we look at your existing electrical panel, your wall layout, and what can realistically fit. A kitchen remodel in Alhambra typically runs $14,000 – $45,000 for a full gut-and-replacement, and a small kitchen update can be done for $9,000 – $20,000 depending on cabinet quality, countertop material, and whether the footprint changes. Bathroom remodels run $9,000 – $28,000, with smaller baths starting at $5,000.
Home Additions and ADUs
Adding square footage in Alhambra means working with the city’s setback requirements, lot coverage limits, and the reality of an older foundation. A home addition in Alhambra runs $45,000 – $130,000 depending on size, foundation work, and finish level. ADU construction runs $90,000 – $220,000, and we handle the full process: plans, permits, construction, and final inspection. If you’re considering an ADU on your Alhambra property, we’ll walk you through feasibility first, before you spend money on plans that won’t pass plan check.
Residential General Contractor in Alhambra
A Residential General Contractor in Alhambra handles renovations, additions, and remodels for existing homes rather than new commercial construction. Mason Remodeling is a residential general contractor, and that focus matters. We know how to work around the framing of a 1952 ranch house, how to upgrade a 100-amp panel before roughing in new appliance circuits, and how to keep a family living in the home during a remodel when that’s what the project requires.
Most of our Alhambra work starts with a simple question: what do you actually want to change, and what will the city require for us to do it legally? We provide a written line-item quote before any work begins. Not a verbal estimate that grows. Not a “we’ll figure it out as we go.” The price you approve is the price you pay, unless you change the scope, and if you do, you approve a written change order first.
Scope, Permits, and Written Pricing
On a 1952 ranch house off South Marengo Avenue near Almansor Park, our crew opened up a galley kitchen for a young family. KraftMaid cabinets, a Cambria countertop, and a new Kohler sink, all after pulling an Alhambra building permit and relocating two non-load-bearing walls. The panel had to be upgraded before we could rough-in the new appliance circuits, which the homeowners approved as a written change order, and the job closed clean after the final inspection sign-off. That’s how our Alhambra projects go: planned, permitted, and priced in writing.
Working Around Older Alhambra Housing Stock
Alhambra’s mid-century tract homes, especially the thousands of 1,100 – 1,500 sq ft houses built in the 1940s and 1950s, often have minimal wall space and older 100-amp electrical panels that force a general contractor to plan cabinet runs, appliance placement, and rough-in around what the house can actually support before any scope is priced. What works next door in a newer San Gabriel Valley city can fail plan check here if the scope ignores Alhambra’s older housing stock and panel limitations. We plan for that from day one.
Trusted Brands We Service in Alhambra
We work with specification-grade material partners so Alhambra homeowners get access to vetted, professional-grade products in one place. Our cabinet lines include KraftMaid and Wellborn, our countertop partners include Cambria and Silestone, and our fixture lines include Kohler, Moen, Toto, and Grohe. For roofing work, we partner with GAF and CertainTeed; for hardscaping, Belgard and Tecoblock. We also stay current with modular and prefab options from builders like Abodu and Cover when a homeowner wants to explore ADU construction. Because we order directly through these partners, we can quote realistic lead times and get materials onto your Alhambra job site without the supply delays that stall smaller remodelers.

AfterCommon General Contractor Problems We See in Alhambra Homes
- Skipping a permit and inspection sign-off for wall removals or electrical rough-in. It saves a few weeks upfront but trips up resale later, and retroactive corrections cost more than doing it right the first time.
- Quoting a kitchen or bathroom off a verbal wish list instead of a written scope of work with allowances. Once the subfloor or old wiring is exposed, the final price drifts badly, and the homeowner is stuck with a number they never approved.
- Treating a load-bearing wall like a cosmetic change. In older Alhambra homes, that means unplanned engineering, new framing, and a change order the homeowner didn’t budget for.
- Overlooking an older 100-amp panel during the planning phase. The panel can’t support new appliance circuits, and the homeowner learns about the upgrade the same week the electrician arrives.

FAQs About General Contractor in Alhambra

If the wall is load-bearing or contains electrical or plumbing, yes, you need an Alhambra building permit, and in most cases the city wants an inspection sign-off before the work is covered up. Removing a wall without a permit can complicate resale and force a costly retroactive correction later. Mason Remodeling pulls permits and schedules inspections as part of the written scope of work. Call (803) 680-2547 and we’ll tell you whether your specific wall is load-bearing before you commit to anything.
Most Alhambra kitchen remodels take 6 to 12 weeks from the signed contract to final inspection, depending on whether the footprint changes, whether the panel needs upgrading, and how quickly materials arrive. Alhambra’s mid-century homes often add a week or two for panel work or unexpected framing, but we build that into the schedule up front rather than springing it on you mid-project. We provide a written timeline with the written price.
We handle the whole job. Mason Remodeling is a general contractor of record, so we manage demolition, framing, electrical, plumbing, drywall, tile, cabinetry, countertops, and finish work.

The most common change orders in Alhambra bathrooms come from what’s found when the walls open up: rotted subfloor, old cast-iron drain lines, or a shower valve that’s behind a wall we didn’t plan to open. Those are written change orders you approve before we proceed, never surprises on the final bill. We can’t see behind your walls before demo, but we price allowances into the written quote so you know what to expect. Call (803) 680-2547 for an exact quote on your bathroom.
