AfterConstruction Services in San Dimas, CA
If you own a home in San Dimas, odds are you’ve already run into the hillside factor. Maybe a contractor told you your project needs geotechnical review before permits will go through, or you discovered your street falls under county jurisdiction while the house next door falls under city. Those surprises stop a project cold. Barrett & Sons Construction has worked through enough San Dimas hillside and wildland-interface builds to spot those snags before you’ve spent a dollar on plans. Call (877) 610-1318 and you’ll get Tom Barrett or one of his sons on the line, not a call center.

Why San Dimas Homeowners Choose Barrett & Sons Construction
We’re the owner-operated crew, founded in 1998, where the name on the truck is the name that answers the phone. Tom Barrett and his sons run the jobs themselves. When we quote a price, it’s the price on the contract. When a change comes up mid-project, it arrives as a written change order before any work moves. No allowances left to interpretation, no final bill that looks nothing like the first estimate. The owners of the homes in the Via Verde foothills and along Foothill Boulevard tell us that’s exactly what they wanted after getting burned by outfits that quoted low and invoiced high.
Every Barrett & Sons job that requires a permit gets a permit pulled and an inspection signed. The inspector works for you, not for us, and that’s why we like having them involved. We also back every completed project with our 90-Day Done Right Promise in writing. Something isn’t right after we leave? One call brings Tom back. That’s not a slogan; it’s on the contract.
Construction Services We Offer in San Dimas
Kitchen Remodeling
A San Dimas ranch built in the 1960s usually has a closed-off kitchen that fights the way people live now. We open those walls, move plumbing where it needs to go, and install named brands like KraftMaid cabinetry and Cambria quartz so you know exactly what you’re getting. Learn more about Kitchen Remodeling in San Dimas.
Bathroom Remodeling
Hillside homes around San Dimas often have bathrooms with moisture issues tied to older venting and framing. We correct that before tile goes up, so the remodeled bathroom stays dry for decades. Learn more about Bathroom Remodeling in San Dimas.
Roofing
For homes inside the Very High Fire Hazard Severity Zone, a new roof in San Dimas isn’t a style decision; it’s a Chapter 7A compliance decision. We install Class A rated roofing from GAF and CertainTeed, with the ember-resistant vents and assemblies your plan checker will look for. Learn more about Roofing in San Dimas.
Windows & Doors
Replacing old single-pane windows with Windows & Doors in San Dimas changes how the house holds temperature during Santa Ana season. We install Andersen and Marvin products sized and flashed correctly for San Dimas’s wind-driven rain and ember exposure.
Fence Installation
Wood fencing on hillside parcels takes more than post holes; slope and soil movement mean the post depth and concrete detail matter. We set fences the way the grade demands, so they stay square through wet winters and dry summers.
Driveway & Pavers
We install paver driveways and walkways using Belgard and Techo-Bloc systems with a base built for San Dimas’s expansive clay soils. That means an extra step most bids skip, and it’s the step that prevents a paver job from heaving in three years.
Home Additions & ADU
Adding square footage on a hillside parcel in San Dimas usually triggers geotechnical review and grading checks before the first inspection. We handle the engineering coordination, the permits, and the construction under one scope, one contract, and one set of written change orders if anything shifts.
Neighborhoods We Serve in San Dimas
Our crews know the grid down by the 57 and the winding roads up toward the foothills. We’re regularly on jobs in these parts of San Dimas:
- Via Verde and the northern foothill parcels
- The neighborhoods along Foothill Boulevard and Arrow Highway
- Homes near San Dimas Canyon Park
- The tract-home grid around Lone Hill Avenue
- Subdivisions east of the 57 near the 91773 ZIP
Typical response time for a San Dimas estimate visit runs within a few business days, scheduled when you’re home to walk the project with Tom or one of his sons.
Why San Dimas’s Climate & Housing Affect Construction
San Dimas sits where the San Gabriel Mountain foothills drop into developed neighborhoods, and that border changes everything about a bid. Large sections of the city fall inside California’s Very High Fire Hazard Severity Zone, which means new construction, additions, and significant remodels must meet CBC Chapter 7A standards: Class A roofing, ember-resistant vents, and ignition-resistant exterior assemblies. Those requirements don’t apply to jobs a few miles south in Covina or West Covina. A San Dimas construction scope is structurally different from a flatland city scope, and any contractor who bids it the same way has already missed the expensive part.
So there’s the fire code angle. Then there’s the housing stock itself. San Dimas was largely built between the 1950s and 1980s. The flatter grid holds ranch-style tract homes with standard foundations. The northern foothill parcels hold custom-graded homes with cut-and-fill conditions, aging retaining walls, and foundations tied to slope performance. Those properties regularly need geotechnical review before permits get issued under current city and LA County grading ordinances. Post-fire debris flows and wet-winter runoff from the mountains also create recurring demand for drainage work and slope stabilization above the residential zones.
One more thing that catches people off guard: parcels on the same street in northern San Dimas can fall under City of San Dimas or unincorporated Los Angeles County jurisdiction, each with a different plan-check process and a slightly different read of Chapter 7A. We identify that before submittal. It’s the kind of thing that stalls a project mid-permit when nobody caught it early.

Honest numbers up front, because that’s the whole point. Here’s what we’re seeing on typical San Dimas jobs:

FAQs About Construction in San Dimas
Kitchen Remodeling - San Dimas typically lands between $38,000 and $85,000, with the bigger number coming from hillside homes where wall movement or foundation shimming adds scope. The single biggest variable is whether we’re opening walls and moving plumbing or refreshing cabinets and counters in place. Call (877) 610-1318 for a written, line-item estimate on your home, free of charge.
Most additions on San Dimas hillside or cut-and-fill parcels do require geotechnical review before permits are issued, and some also need grading plan approval through LA County. We coordinate the engineer, the reports, and the submittal so you’re not chasing paperwork across two jurisdictions. Call (877) 610-1318 and we’ll tell you whether your specific parcel triggers it.
Chapter 7A is the California code section that governs construction in Very High Fire Hazard Severity Zones, and much of San Dimas falls inside that boundary. For a roof, that means Class A rated material, specific underlayment, and ember-resistant venting. We install GAF and CertainTeed systems as part of our Roofing in San Dimas, and we make sure your plan checker sees the right specifications on the submittal.
Only if you approve it in writing. Every change at Barrett & Sons arrives as a written change order before any work happens. Our standing rule: the allowance that isn’t on paper is a surprise waiting for a date. You’ll never see a price change on a final invoice that wasn’t handed to you first.
Yes, on every eligible job. The permit inspector works for you, not for us, and that’s why we like them involved. Any contractor who tells you permits are optional on a remodel or addition in San Dimas is telling you something that won’t help you when you sell the house. Call (877) 610-1318 for a free estimate, and we’ll tell you exactly what your job needs.

What San Dimas Customers Say
"His sons run the crews and they were in our house for four months. Not once did I feel I had to be home to keep an eye on things."
- Camila Fuentes"Beautiful work and honest pricing throughout. The project ran about three weeks past the estimate waiting on the cabinets, which was the supplier rather than him, though the delay was still real."
- Genevieve Ashcombe"Full kitchen down to the studs. He found the previous owner had done the wiring himself and it was genuinely dangerous, showed me, and put it right properly rather than boxing it back in."
- Augustus Nwachukwu
