Fast, Reliable General Contractor Across San Dimas
General contractor work in San Dimas runs $4,500 for a concrete driveway up to $130,000 for a home addition, with most hillside re-roofs and exterior re-clads falling between $8,000 and $20,000 because of the Very High Fire Hazard Severity Zone requirements. We’re the General Contractor team families call when the project sits in a fire zone, a debris flow hazard area, or both, and they need every permit detail documented for their insurance carrier. Dispatch and scheduling are coordinated from our Los Angeles office, but our crews serve San Dimas locally and know the difference between a valley floor permit on a 1970s tract slab and a hillside plan check on San Dimas Canyon Road.

Why Elmstead Remodeling Is San Dimas’s Preferred General Contractor Company
We’ve worked the split housing stock here long enough to know which 1960s tract home has the original wood shake roof that won’t pass insurance renewal, and which custom hillside place on a graded pad needs deeper footings before the county will sign off. Our Cedarwell Care Promise means shoe covers and drop cloths on every visit, a written price before any work starts, and a photo of the clean-up before the crew leaves. Families with children and pets hire us because we use quiet tools during nap and school hours where possible, and we ask before moving anything. The 365-Day Done Right Promise covers every completed project, if it’s not done right, we make it right. Graham Stein leads our operation, and phones are answered by a live person 24/7, not a voicemail box, not a bot.
Styles & brands we work with
General Contractor Services in San Dimas
General Contractor Services in San Dimas cover everything from valley floor kitchen and bathroom remodels to hillside re-roofs, room additions, and whole-home renovations that must clear LA County Fire’s Wildland-Urban Interface codes. A typical kitchen remodel here runs $14,000 – $45,000, a small kitchen $9,000 – $20,000, and a bathroom remodel $9,000 – $28,000. Home additions range $45,000 – $130,000. But the projects that define our San Dimas work are the ones where fire zone compliance and debris flow geology intersect with standard remodeling, and the quote has to account for both.
Fire-Zone Re-Roofing and Exterior Re-Clad
Original wood shake roofs on hillside properties must come off. We tear to Class A roofing, swap eave and under-floor vents to ember-resistant assemblies, and install non-combustible cladding within five feet of the structure. This is not an upgrade we suggest. It’s what the VHFSS designation requires, and what your insurance carrier will ask for documentation of at renewal.
Room Additions and Whole-Home Remodels
Additions in San Dimas need structural calculations that account for Santa Ana wind loads and thermal expansion from 100°F summer highs. We specify stucco mixes and control joint spacing for inland foothill conditions, not coastal formulas. The written price includes these material specs before any work starts.

Construction Company in San Dimas
Construction Company work in San Dimas means understanding two building environments on the same permit desk: conventional slab foundations on the valley floor, and raised foundations on graded pads with retaining walls in the hills. A concrete driveway installation runs $4,500 – $12,000 on flat ground. But on San Dimas Canyon Road and above, we routinely submit upgraded drainage plans with deeper footings before the plan check clears, because LA County Fire and city reviewers reject flat-lot details that pass a block away. This is the local knowledge that separates a compliant quote from a mid-job change order.
Debris Flow Zone Footing and Drainage
USGS-mapped post-fire debris flow hazard zones cover hillside properties on and above San Dimas Canyon Road. We deepen footing details and tie site drainage into sediment-managed discharge. The county inspector won’t sign off without it. We itemize this in the written proposal, never bury it in a vague allowance.
Metal Roofing and Impact Windows
Metal roof installation runs $15,000 – $40,000 and carries a Class A rating natively. Impact window installation runs $8,000 – $25,000. Both products satisfy WUI requirements and come with manufacturer warranties you can verify independently. We document every rating label for your insurance file.
Trusted Brands We Service in San Dimas
We stock and install products with warranties that travel with the finished project: cabinets from KraftMaid and Wellborn, countertops from Cambria and Silestone, fixtures from Kohler, Moen, and Grohe, exteriors from James Hardie and GAF. For fire-zone and debris-flow projects, we also source Sakrete for structural concrete and specify Schluter waterproofing assemblies where drainage is critical. San Dimas homeowners can research every brand by name, and we keep common items on hand so valley floor jobs don’t wait on a truck from out of county. The materials list in your written proposal matches what arrives on the job, no substitutions without sign-off.

AfterCommon General Contractor Problems We See in San Dimas Homes
- Wood shake roofs denied insurance renewal. The original 1970s shake on hillside homes won’t satisfy the VHFSS requirement. We see homeowners caught mid-remodel when the carrier demands Class A documentation before releasing funds.
- Thermal expansion cracking in stucco and concrete. San Dimas’s 100°F summer highs and strong Santa Ana winds stress flatwork and exterior finishes. We specify inland-formula stucco mixes and control joint spacing tighter than coastal standards.
- Debris flow zone surprises at plan check. Contractors quoting hillside work with valley-floor drainage details get rejected. The correction becomes a change order. We submit upgraded plans upfront.
- WUI upgrades buried in vague allowances. Low bids itemize standard roofing but bury ember-resistant vents and non-combustible cladding in a single “fire zone adder.” We line-item every WUI component so you know what the code requires versus what we’re recommending.

FAQs About General Contractor in San Dimas
Yes, if your property is in the Very High Fire Hazard Severity Zone, which covers most hillside areas and many valley floor neighborhoods in San Dimas. LA County Fire enforces California’s WUI building codes: Class A roofing, ember-resistant venting, and non-combustible exterior cladding within five feet of the structure. Your insurance carrier will ask for documentation of compliance at renewal. Call (949) 850-9896 and we’ll verify your parcel’s zone status during the free estimate.
These properties sit in USGS-mapped post-fire debris flow hazard zones, and LA County permit reviewers routinely reject flat-lot drainage and footing details that pass on the valley floor. We submit upgraded drainage plans with deeper footings before plan check, so the job doesn’t stall mid-construction. Call (949) 850-9896 to review your specific site’s requirements.
Documented compliance, rating labels, inspection sign-offs, and photos of installed ember-resistant vents and non-combustible cladding, gives your carrier proof of risk reduction. Some carriers offer premium adjustments for documented WUI upgrades. We provide the full documentation package at project closeout. Call (949) 850-9896 to discuss what your carrier requires.
Itemized WUI materials with brand and rating, debris flow zone footing and drainage details if applicable, permit and inspection fees, and a line-item for sediment-managed discharge where required. Cheap bids bury these in vague allowances or omit them entirely, then add them as change orders. Our written price includes every code-required element before any work starts. Call (949) 850-9896 for a proposal you can compare line by line.
Yes. The inland foothill position produces stronger wind loads and wider temperature swings than coastal zones. We specify structural connections and stucco mixes rated for these conditions, with control joint spacing that accounts for thermal expansion. This is standard in our San Dimas additions, not an upgrade. Call (949) 850-9896 to review the structural specs in your written estimate.
Last fall we took a hillside re-roof and exterior re-clad on San Dimas Canyon Road where the original wood shake had to come off to satisfy the Very High Fire Hazard Severity Zone requirement before the insurance carrier would renew, we tore off to Class A roofing, swapped the eave and under-floor vents to ember-resistant assemblies, and installed non-combustible cladding within five feet of the structure. Because the same graded pad sits in a mapped debris flow zone, we also deepened the footing details and tied the new site drainage into a sediment-managed discharge before the county inspector would sign off. The homeowner had a full documentation packet for their carrier and no change orders. That’s how we work every San Dimas project.
