Remodeling Company in San Dimas, CA
Mason Remodeling handles full-scale construction work across San Dimas, CA, with written pricing delivered before any work begins. Most San Dimas homes we step into were built between the 1960s and 1990s, which means the framing, electrical, and plumbing rarely match what today’s code expects. That older housing stock, combined with the foothill heat and wildfire-adjacent terrain, makes remodeling here different from work down in the flatlands. Call (803) 680-2547 for a free estimate and we’ll tell you exactly what your project will cost.
Why San Dimas Homes Are Different

San Dimas sits against the San Gabriel foothills, and the terrain shapes every job we take on. Much of the city climbs away from Foothill Boulevard and Bonita Avenue, which means foundations often step with the grade, drainage has to be thought through carefully, and access for a dumpster or material delivery can get tight on the hillside streets above San Dimas Canyon Road. Homes near the San Dimas Canyon Golf Course or along Via Verde tend to have larger lots and more exposed hillside, while the neighborhoods between Arrow Highway and the 57 freeway are older, flatter, and built on soils that shift with the seasons.
The second thing that sets San Dimas apart is the heat. Summer temperatures regularly sit above 95 degrees, and stucco exteriors take the brunt of that sun year after year. We see cracked stucco, dry-rotted eaves, and window seals that have given up long before the homeowner notices a draft. When we open a wall in an older San Dimas home, we are rarely surprised by what we find, but we always write the quote so the homeowner isn’t surprised by the number. Wildfire proximity also matters. Homes in the northernmost parts of the city, toward the canyon mouths, often need exterior work done with fire-resistant materials that meet current San Dimas building requirements.
Styles & brands we work with







Our Main San Dimas Services
General contracting and whole-home work are the two things San Dimas homeowners call us about most. Here’s what each involves and where to find the full detail.
General Contractor in San Dimas
As a general contractor, we handle the messy, structural side of a project: load-bearing wall removal, foundation work, rough framing, windows, roofing, and bringing every rough-opening up to current code. San Dimas permits are particular about hillside setback changes and any work that touches a retaining wall, and we pull those permits ourselves so they pass inspection the first time. You’ll know exactly who is on-site each day, because every crew member is background-checked, identity-verified, and arrives with a photo ID badge. See General Contractor in San Dimas for full scope and pricing.

Bathroom Remodeling in San Dimas
Most San Dimas bathrooms we remodel were built when a single vanity and a fiberglass tub surround were standard. The work usually means pulling the old tub, repairing the framing under it, moving or adding plumbing for a walk-in shower, and handling the waterproofing properly so hillside moisture never becomes a problem. We use Schluter strip, the metal trim that seals the edge where tile meets flooring, on nearly every job because it lasts longer than caulk and looks cleaner. Get the details at Bathroom Remodeling in San Dimas.

Home Remodeling in San Dimas
When the project touches multiple rooms, a whole-home remodel usually starts with the floor plan and the mechanicals. In San Dimas, that often means replacing a 40-year-old electrical panel, upgrading old galvanized supply lines, and reworking ductwork before any finish material goes in. We coordinate the trades so the dust is contained, the dumpster is staged where the street allows, and the water stays on when you need it. Every home remodel gets a written price before work starts and a written guarantee with clearly stated terms. Read more at Home Remodeling in San Dimas.

Hillside lots push costs upward faster than anything else in San Dimas: foundation step-downs, retaining-wall engineering, and longer dumpster or material runs all add labor hours.
