We work throughout Claremont, from the tree-lined streets of the Village to newer subdivisions north of Base Line Road. Our scheduling team coordinates from the brand’s Los Angeles office, and crews serve Claremont directly. The result is the same Threshold Verified standard on every job: background-checked technicians in clean marked uniforms, photo ID badges at the door, and a written guarantee covering 365 days from the completion date.

Why Mason Remodeling Is Claremont’s Preferred General Contractor Company

A single-story rear room addition with tall windows and a new patio

Claremont homeowners deal with a building department that most neighboring cities don’t have. The City of Claremont runs its own plan check and inspection process, separate from LA County. That means permit timelines, rough-in inspections, and final sign-offs work differently here than in Montclair or Upland. Our team knows the Claremont building department’s process, which means fewer surprises on inspection day and fewer delays while a permit sits in review.

Mason Remodeling has been doing residential construction since 2004, operating as part of the Threshold Group family of home-service companies. Every Claremont project meets the Threshold Standard: identity-verified crew members, written pricing before work begins, and a written guarantee with clearly stated terms. If a repair or installation fails within 365 days, we return and make it right at no cost.

Isaac Pruett leads our team. Homeowners who call (803) 680-2547 speak to a live person, 24 hours a day, 7 days a week. No call trees, no voicemail loops, no waiting until Monday morning to get a question answered.

Residential General Contractor in Claremont

Residential General Contractor work in Claremont is about scoping a project correctly before a single wall is opened. That means understanding what is behind the walls of a 1925 bungalow near Indian Hill Boulevard, what the city’s own building department will require at inspection, and what the final finishes actually cost. A homeowner who skips that scoping step ends up with change orders, blown budgets, and a project that sits half-finished.

When you hire Mason Remodeling as your General Contractor, the first milestone is a written line-item scope and price. Not a ballpark. Not a verbal estimate. A written price covering the specific work, delivered before we unpack a single tool.

Kitchen and Bath Remodeling

Kitchen remodels in Claremont typically run $14,000 to $45,000, depending on layout changes, cabinetry grade, and whether structural work is needed. Bathroom remodels run $9,000 to $28,000. In older Village homes, expect the “behind the walls” scope to matter: rot repair, outdated plumbing, and missing fire blocking are common finds.

Whole-Home and Addition Work

A home addition in Claremont runs $45,000 to $130,000. ADU construction runs $90,000 to $220,000. These are permit-heavy projects, and Claremont’s local building department means plan check happens inside the city, not through the county. We handle the plans, permits, and inspections as part of the written scope.

Hire a General Contractor in Claremont

A garage converted into a guest room and home office

Hire a General Contractor in Claremont when the project involves permits, structural changes, or coordinating multiple trades. You don’t want to manage an electrician, a plumber, a drywaller, and a tile setter yourself, and you don’t want to learn Claremont’s local inspection requirements by getting red-tagged. A general contractor handles the trade coordination, the permit paperwork, and the schedule.

We serve homeowners across Claremont, including the Village, Claraboya, and neighborhoods near Thompson Creek. Each project gets a dedicated point of contact, a written schedule with realistic milestones, and a final punch list that is completed before final inspection.

Permit and Inspection Management

Claremont is one of the few LA County cities still using its own building department. That is not a small detail. Plan check timing, required corrections, and inspection scheduling all follow Claremont’s rules, not the county’s. We pull permits, coordinate inspections, and walk the project through to final sign-off.

Written Price, No Allowance Games

The most common budget blow-up in Claremont renovations is low allowances. A contractor quotes $4,000 for cabinetry when the client actually wants KraftMaid or Wellborn cabinets and Cambria counters. Then the change order arrives and the budget is gone. Mason Remodeling prices the actual finishes you choose, in writing, before work starts.

Trusted Brands We Service in Claremont

We install and service specification-grade products from Cambria, Silestone, KraftMaid, Wellborn, Kohler, and Moen. Because we have direct material partnerships, Claremont customers get access to professional-grade products at pricing that reflects our standing as a Threshold Group company. We also work with modular and prefab building systems from Dvele and Abodu for ADU and addition projects where off-site construction shortens the on-site calendar. Parts and materials are ordered early so the schedule doesn’t stall waiting on a backordered cabinet or a special-order countertop.

Common General Contractor Problems We See in Claremont Homes

  • Missing structural headers in pre-1950 Village homes. On a 1920s bungalow near Harvard Avenue and Bonita Avenue in the Claremont Village area, our crew opened a kitchen wall and found no structural header. It was load-bearing, so we pulled permits, added an engineered beam, and coordinated inspection sign-off before drywall.
  • Knob-and-tube wiring uncovered during remodel work. Many Claremont homes built before 1950 still have active knob-and-tube circuits. Open a wall for a kitchen remodel and you may find wiring that needs to be replaced before the city will pass rough-in inspection.
  • Undersized floor joists causing tile failure. In older Claremont homes, floor joists were often sized for the loads of 1925, not for a modern tile floor over Schluter membrane. We check deflection before tile goes down, because cracked grout six months later is not a warranty issue, it’s a structural one.
  • Claremont-specific plan check surprises. Because Claremont runs its own building department, requirements that are routine in Ontario or Upland may be handled differently here. We know the local process and build it into the schedule from the start.
