Remodeling Company in San Dimas, CA
Mason Remodeling handles whole-home, kitchen, and bath work across San Dimas, where foothill terrain and homes built from the 1950s through the 1980s create conditions most flatland remodelers never see. Sloping lots, clay-heavy soils that expand and contract through hot summers and winter rains, and older ranch layouts mean every project here starts with a closer look at drainage, foundation movement, and existing plumbing. We send background-checked, uniformed crews you can identify by name and photo before they arrive, and every San Dimas job gets a written price before any work begins. Call (707) 760-7579 to talk through your project.
Why San Dimas Homes Are Different

The northern foothills above Foothill Boulevard hold some of the trickiest residential lots in the San Gabriel Valley. Homes sit on graded slopes where runoff moves fast during winter storms, and we regularly see retaining walls that were never engineered for the soil pressure behind them. Foundation cracks here are not cosmetic – they follow the seasonal swell and shrink of expansive clay, so we assess movement patterns before we ever suggest a remodel scope.
Much of the housing stock dates to the 1950s through 1980s, built with cast-iron drain lines that hard water has spent decades corroding. In hillside neighborhoods, it is common to open a wall for a kitchen or bath job and find drain pipe that crumbles when touched. That is a San Dimas reality, not a rare surprise. Wildfire defensible-space rules also affect what can be built, where, and with what materials in the foothill zones, and seismic retrofitting often enters the conversation when an older single-story ranch is getting a major addition or reconfiguration.
Styles & brands we work with







Our Main San Dimas Services
These three services cover what San Dimas homeowners call us about most often. Each has its own detailed page with pricing, timelines, and the specific ways we handle older homes on sloping lots.
General Contractor in San Dimas
As a General Contractor in San Dimas, we coordinate additions, seismic retrofits, retaining-wall repair, and whole-home structural work. Hillside projects here often need engineered drainage corrections before framing begins, and we sequence that work so your permit inspection passes without rework. Every subcontractor on your job goes through the same background-check and photo-ID verification as our own crew, and no change order is ever sprung on you mid-job.

Bathroom Remodeling in San Dimas
Older San Dimas bathrooms hide corroded cast-iron drains, improperly sloped vent lines, and water-damaged subfloor around tubs and showers. Our Bathroom Remodeling in San Dimas page covers how we replace drain stacks, re-level floors on settling foundations, and build walk-in showers that account for hillside framing movement. Homeowners receive the name and photo of every technician before the appointment, and a written price before demo day.

Home Remodeling in San Dimas
Home Remodeling in San Dimas means working around lived-in layouts from a time when closets were small, kitchens were closed off, and footprint mattered more than flow. We open floor plans carefully on older ranch homes, often adding beams where load-bearing walls come out and upgrading electrical panels that are decades past their original load calculation. The 365-Day Done Right Promise covers every whole-home project we complete here.

Brands We Service in San Dimas

Two things push pricing higher in San Dimas specifically: hillside engineering and old-pipe replacement. When a remodel uncovers corroded cast-iron drain lines or needs a new retaining wall before framing starts, those are real line items – never surprises. Every project gets a written price before work begins, and that price states exactly what is covered, what is excluded, and for how long.

FAQs About Remodeling Company in San Dimas

Estimate visits are typically scheduled within one to two business days for most San Dimas neighborhoods.
