Fast, Reliable General Contractor Across San Gabriel

Most San Gabriel remodels come down to two things: getting the scope priced honestly and keeping the permit process from eating your calendar. We’re Mason Remodeling, and we’ve worked on enough pre-1960s San Gabriel homes to know what’s behind those plaster walls before we open them. Whether you’re planning a kitchen remodel near Las Tunas Drive or an ADU on a 50-foot lot off Valley Boulevard, our General Contractor team gives you a written price before any work starts, then holds it. Call (803) 680-2547 for a free estimate.

Why Mason Remodeling Is San Gabriel’s Preferred General Contractor Company

A wide opening with a new beam where the kitchen wall was removed

San Gabriel homeowners tell us the same thing again and again: they want to know exactly who’s walking through the door. That’s why every Mason Remodeling crew member is background-checked, identity-verified, and introduced to you by name and photo before the visit. The Threshold Standard isn’t a marketing phrase here – it’s the process our crews follow on every job in San Gabriel, from a small bath refresh to a full second-floor addition.

Our reputation in San Gabriel is built on the 365-Day Done Right Promise. If the work isn’t right within a year of completion, we make it right at no cost to you. That covers general contracting, bathroom remodeling, and whole-home remodels. Isaac Pruett, our owner, set that standard in 2004 when Mason Remodeling was founded as part of the Threshold Group family of home-service companies, and it hasn’t changed since.

Pricing is the other reason San Gabriel homeowners choose us. You receive a written price before any work begins – not a verbal ballpark, not an estimate that grows. Dispatch and scheduling are coordinated from our Los Angeles office, and crews serve San Gabriel directly. When you call, a live person answers. No phone trees, no voicemail loops.

Construction Company in San Gabriel

A Construction Company in San Gabriel does more than build – it manages the details that make or break a project. When you’re adding square footage to a 1950s ranch house or converting a garage into a rental unit, you’re dealing with structural work, rough-in inspections, and the city’s outside plan-check agency. Our team handles the full scope: framing, drywall, electrical, plumbing, and finish work, all sequenced so inspections happen when they should.

What does that cost in San Gabriel? A garage conversion typically runs $30,000 – $80,000. A home addition starts around $45,000 and can reach $130,000 depending on square footage and site conditions. An ADU is a bigger lift: $90,000 – $220,000 in this market. Those are honest ranges, not teaser numbers. We’d rather tell you the truth on the first visit than hand you a change order on week six.

Structural Work and Load-Bearing Walls

Most San Gabriel homes were built before 1960, which means a wall that looks non-structural usually isn’t. Opening up a kitchen into a dining room often means reframing a header and sistering floor joists. We catch these issues at demo, not after drywall goes up, and we document every cost shift in writing.

Foundation and Subfloor Repairs

Older San Gabriel slab and raised foundations settle. When a subfloor is out of level by an inch across a room, tile and cabinetry suffer. We level subfloors before setting anything on top, because a straight line on an uneven floor just makes the flaw more visible.

Remodeling Contractor in San Gabriel

A garage converted into a guest room and home office

A Remodeling Contractor in San Gabriel has to respect the city’s older housing stock and its planning rules. Kitchens and baths in homes near San Gabriel Boulevard and Mission Road often sit on small footprints with awkward plumbing locations. Moving a sink or toilet isn’t just cosmetic – it changes the rough-in schedule and the permit scope. We plan for that from day one.

Kitchen remodels in San Gabriel run $14,000 – $45,000, with small kitchens starting around $9,000 – $20,000. Bathrooms run $9,000 – $28,000. Cabinets alone cost $4,000 – $13,000 installed, and countertops add $2,000 – $6,500. These aren’t numbers pulled from a national average. They’re what we’re quoting in San Gabriel right now, accounting for the age of the homes and the realities of the permit process here.

Kitchen and Bath Demolition

Demo in a pre-1960s San Gabriel home isn’t a one-day job. Plaster and lath are heavy and dusty, and we protect the rest of the house with containment before we open anything up. We also check for original wiring that may need replacing under current code.

Rough-In and Inspections

San Gabriel contracts plan review through outside agencies, which means plan-check comments often arrive in waves. We schedule rough-in inspections early and assume the permit clock will run longer than it does in neighboring cities. It’s not a delay we cause – it’s the way this city works.

Trusted Brands We Service in San Gabriel

We’re specification-grade partners with KraftMaid and Wellborn cabinetry, Cambria and Silestone surfaces, and Kohler, Moen, and Toto fixtures. That means San Gabriel homeowners don’t have to shop at big-box stores and hope for the best. We order directly and handle the install. We also service homes built with panelized systems from manufacturers like Abodu and Cover – if you have one of those units on your San Gabriel lot, we can tie into it properly with the same written-price standard we apply to every other project.

Common General Contractor Problems We See in San Gabriel Homes

  • Load-bearing “galley” walls: The 1950s kitchens in San Gabriel often look simple, but the wall between the kitchen and dining room is frequently carrying the roof. We find this at demo and reframe properly rather than tearing it out and hoping.
  • Out-of-level subfloors: Older raised foundations settle unevenly. A floor out by an inch across a 10-foot run means cabinets won’t sit flush. We level before we install, and we tell you what that costs up front.
  • Waves of plan-check comments: San Gabriel’s outside review agency doesn’t always return one clean set of comments. We’ve seen projects where the rough-in was ready but the plan check still had open items. We sequence work so your calendar suffers as little as possible.
  • Low allowance quotes: Some contractors quote builder-grade allowances to win the bid, then charge change orders when you pick KraftMaid cabinets or Cambria quartz. Our written price includes the actual products we’re installing, not a placeholder number.
