AfterFast, Reliable General Contractor Across San Dimas
Finding a General Contractor in San Dimas who returns calls, shows up when they say they will, and puts prices in writing before a single wall is opened shouldn’t be this hard. We’re Penhallow Remodeling, and our crews work San Dimas neighborhoods from Via Verde to the foothill tracts off San Dimas Canyon Road every week. If you’re planning a kitchen remodel, bathroom update, or whole-home renovation, call us at (936) 259-2607 and we’ll schedule a walkthrough, inspect what’s behind the walls, and hand you a written scope and price you can hold us to.
Why Penhallow Remodeling Is San Dimas’s Preferred General Contractor Company
San Dimas homeowners have a specific kind of project: homes built between the 1960s and 1980s that have been lived in hard, remodeled in pieces, and now need someone who understands what code requires once the drywall comes down. Our reputation in this city comes from doing the unglamorous part right. We answer the phone. We arrive in a defined window. We write down what we’ll do, what it costs, and how long the guarantee lasts. Then we do the work and leave the job site broom-clean.
Trevor Nash leads our team, and his rule with every San Dimas job is the same: if the price changes, the change happens in writing and only after you approve it. No verbal ballparks that balloon after demo day. No “we didn’t know the wiring was that bad.” We build the likely surprises into the contract as allowances from the start, so the number you approve is the number you pay unless you choose to expand the scope.
We’re part of the Kingswell family of companies, operating under The Kingswell Way since 2004. That means every job gets a written price up front, a real arrival window, a clean job site, and our 365-Day Done Right Promise. If something fails inside a year, we come back and fix it at no charge. A live person answers our phones 24/7, and every technician who walks into your San Dimas home is background-checked and in uniform.
Hire a General Contractor in San Dimas
Hire a General Contractor in San Dimas when your project touches structure, plumbing, electrical, or load-bearing walls. A kitchen remodel in San Dimas typically runs $14,000 – $45,000 depending on cabinet line, countertop material, layout changes, and what we find once walls are open. A bathroom remodel runs $9,000 – $28,000. Those are real ranges, not estimates that drift. The variables are real too: a 1968 ranch off Gladstone Street with cloth-wrapped wiring will cost more up front than a 1990s tract home off San Dimas Avenue, because the wiring and panel work is mandatory, not optional.
Permit-Triggered Code Upgrades
When we pull a permit in San Dimas for a kitchen or bath remodel, the scope often expands to include smoke detector upgrades, GFCI placement, or panel capacity that the original 1970s build never had. We price those in writing as a line item, not as an after-the-fact surprise. Then we let the inspector confirm the work before we close the wall.
What Actually Drives a San Dimas Quote
Three things move the number: the age of the mechanical systems behind the walls, the soil under the slab, and whether the parcel sits above the 1,000-foot contour where VHFHSZ fire code kicks in on exterior work. We walk the site, check the panel, look at the foundation, and then give you a written number that already accounts for what we can see and what experience says we’ll probably find.
General Contractor Services in San Dimas
General Contractor Services in San Dimas from Penhallow Remodeling cover the projects that change how you live in your home. Kitchen remodels, bathroom remodels, whole-home renovations, room additions, and accessory dwelling units all sit inside our scope. A home addition in San Dimas runs $45,000 – $130,000 depending on square footage, foundation condition, and whether the new roofline triggers a VHFHSZ review. An ADU runs $90,000 – $220,000. We quote these honestly, with allowances for the unknowns built into the contract.
Kitchens and Baths on Slab
Most San Dimas homes sit on concrete slabs over expansive clay and alluvial-fan soils. That means when we open a floor for plumbing changes or move a load-bearing wall, we check for cracking, heaving, and moisture intrusion before the framing crew starts. Skipping that step is how a $22,000 kitchen remodel becomes a $38,000 structural correction. We do it first, and we tell you what we find.
Additions in the Fire Hazard Zone
Above roughly the 1,000-foot contour near San Dimas Canyon, an addition or re-roof triggers the county’s VHFHSZ checklist. Class A roofing material, ember-resistant vents, boxed-eave retrofits, and defensible-space clearance all become permit conditions. We build those into the draw schedule and the price from day one, because we’ve done enough foothill work to know the inspector will ask.

Trusted Brands We Service in San Dimas
We install products from brands that stand behind what they make, because our guarantee sits on top of theirs and we don’t want to eat a warranty claim on cheap materials. In San Dimas kitchens and baths, that means Cambria and Silestone countertops, KraftMaid and Wellborn cabinetry, and Kohler or Moen fixtures. For exterior work on foothill homes, James Hardie siding and Class A roofing assemblies hold up to Santa Ana wind events and radiant heat off the San Gabriel Mountains better than builder-grade alternatives. Our supply relationships mean we can source parts locally and keep a remodel on schedule instead of waiting on a backorder out of state.
Common General Contractor Problems We See in San Dimas Homes
- Cloth-wrapped wiring and undersized panels. We regularly open walls in 1960s and 1970s San Dimas homes and find wiring that can’t legally carry the load a modern kitchen or bath requires. We price the panel upgrade and rough-in as a written change order, pull the permit, and let the inspector confirm the work before drywall goes up.
- Foundation cracking on expansive clay. Slab-on-grade homes in San Dimas sit on alluvial-fan soils that swell and shrink with the seasons. Cracks and heaving are common, and any load-bearing change to the floor plan needs a foundation assessment before framing starts.
- Exterior material degradation from Santa Ana winds. San Dimas Canyon funnels wind and radiant heat down the mountain, and stucco cracking, fascia rot, and roof membrane lift happen faster here than in flatland cities like Covina. We inspect hard surfaces and roof assembly condition as part of any exterior scope.
- VHFHSZ triggers on foothill parcels. A re-roof that would be routine in La Verne can require Class A roofing, ember-resistant vents, and defensible-space sign-off once you’re above the 1,000-foot contour near San Dimas Canyon. Flatland contractors miss this, and then the permit stalls. We know it’s coming.
Here’s what that looks like in practice. On a 1972 split-level off Via Verde, our crew opened the kitchen wall for an addition and found cloth-wrapped wiring feeding a 100-amp panel that had no capacity for the new range and hood circuit. We priced the panel upgrade and dedicated rough-in as a written change order, pulled the electrical permit, and let the inspector confirm the in-wall work before we hung drywall. The job closed with a signed punch list and no disputed line items.

FAQs About General Contractor in San Dimas
Because the contractor who quoted it treated the discovery of outdated wiring, undersized framing, or failed waterproofing as an after-the-fact surprise instead of an allowance written into the contract. We price what’s behind the wall from what we can see before we start, write allowances for what experience says we’ll probably find, and put any change in front of you in writing before we touch it. Call (936) 259-2607 and ask for a written quote with the allowances spelled out.
If your parcel sits above roughly the 1,000-foot contour near San Dimas Canyon, the county’s Very High Fire Hazard Severity Zone checklist almost certainly applies. That means Class A roofing material, ember-resistant vents, boxed-eave retrofits, and a defensible-space sign-off before the inspector will close the permit. A flatland price misses these; a foothill price builds them into the draw schedule.
We write them into the contract before work starts. Any addition that requires structural changes, electrical work, or plumbing will trigger code requirements the original 1970s build never had: smoke detector upgrades, GFCI placement, panel capacity, and potentially VHFHSZ exterior standards. We identify which ones your property will face during the walkthrough, price them in writing, and let the inspector confirm the work before we close the walls.
Yes, and we check before we frame. Slab-on-grade homes over San Dimas’s expansive clay and alluvial-fan soils often show cracking, heaving, and moisture intrusion. If you’re moving load-bearing walls or adding square footage, we assess the foundation first, price any correction in writing, and design the structure around what’s actually under the slab. Skipping that step is how a modest remodel becomes an emergency repair.
By putting the most likely surprises into the contract as priced allowances before work starts. For a 1960s or 1970s San Dimas home, that means budget for panel upgrades, cloth-wrapped wiring replacement, possible foundation correction, and VHFHSZ items if you’re in the foothill zone. Then any actual change order comes to you in writing, with a number, and only moves forward after you approve it. Call (936) 259-2607 for an exact quote. Estimates are free.
