Fast, Reliable General Contractor Across Mentone
When a Mentone homeowner needs a kitchen torn out, a roof replaced, or an ADU added on a canyon-side lot, the first question is usually whether one contractor can actually handle all of it. We can. San Bernardino Contractors manages every phase of residential work across Mentone, from the footings up to the ridge cap. If you’re off Mill Creek Road, Crafton, or down near the 38, you already know the terrain here doesn’t forgive sloppy planning. Call us at (855) 473-5620 and we’ll walk the site with you before any numbers get written down.
Why San Bernardino Contractors Is Mentone’s Preferred General Contractor Company
Mentone isn’t a copy of Redlands or Yucaipa, and the work here doesn’t bid like it. The decomposed granite under the foothill parcels changes how footings get dug. The canyon draws change where water goes in a winter storm. Homeowners here tend to have done their homework, and they recognize when a contractor actually knows the difference between a flat-valley bid and a Mentone bid.
We’ve built our reputation in the 92359 zip code on honesty about what the ground and the fire code actually require. That means a written scope of work with real line items for rock-breaking, drainage, and WUI-compliant materials, not a handshake and a surprise change order. Ruben Castillo runs every Mentone project with the same rule: if it’s going to cost more, you hear about it before the dig starts, not after.
Our crews are in Mentone regularly, and when a homeowner calls about a roof that lost shingles to a Santa Ana event or a retaining wall question after the first heavy rain, we can get someone out quickly. Estimates are free, and they’re detailed. Call (855) 473-5620 to get one started.
Styles & brands we work with







Licensed General Contractor in Mentone
A Licensed General Contractor in Mentone has to manage more than the building itself. The San Bernardino County foothills impose grading, drainage, and wildland-urban interface requirements that a contractor working flat lots in Highland rarely deals with. When we take on an addition or full remodel here, the permit package often includes structural, grading, and fire-hardening sign-offs before the first wall goes up. A typical home addition in Mentone runs $45,000 to $130,000, and the range swings on rock conditions, septic capacity, and what the fire code requires for the assembly.
We hold the license, carry insurance, and pull permits on every job that requires them. No side deals, no “we’ll handle it later.” The inspection paperwork we hand over at the end is yours to keep for your insurer.
Foothill Grading and Foundation Work
Digging footings on decomposed granite is slow, loud work. We budget for rock-breaking when the soil report suggests it, and we write the allowance into the contract so the cost is visible from day one. Retaining walls on canyon-side lots get engineered for both the soil load and the runoff that channels down the draws in winter.
Fire-Hardened Exteriors
Mentone sits in wildland-urban interface territory. Roofing, vents, windows, and siding all carry ratings that matter at final inspection and when you file a claim. We install GAF and CertainTeed roofing systems rated for the exposure, and we document every assembly so the compliance trail is clean.
Residential General Contractor in Mentone
A Residential General Contractor in Mentone is really a translator between what the homeowner wants and what the canyon terrain, the county, and the insurance company will accept. We handle kitchens, baths, whole-home remodels, additions, ADUs, and roof-to-paver exterior work. The job is the same shape it would be anywhere else, but the local conditions change the details. A paver patio on a flat Mentone lot is straightforward. The same patio on a sloped parcel off Crafton Road needs compaction, drainage, and probably a small retaining wall to keep it where you put it.
Our remodeling work in Mentone typically runs $14,000 to $45,000 for a kitchen, $9,000 to $28,000 for a bathroom, and $90,000 to $220,000 for an ADU. Those ranges reflect the brands you pick, the condition of the subfloor and framing, and what the ground underneath decides to do.
Kitchen and Bath Remodels
We order KraftMaid and Wellborn cabinetry, Cambria and Silestone countertops, and Grohe or Kohler fixtures depending on where you want to land on the finish spectrum. You pick the brand, we handle the build. A small kitchen remodel in Mentone starts around $9,000, and a walk-in shower conversion can start as low as $4,500.
Additions and ADUs on Septic Lots
Much of Mentone runs on well and septic, not city sewer. That drives decisions on ADU size and placement before a single drawing gets submitted. We check septic capacity, well yield, and grading standards early so the plan that goes to the county actually has a chance of being approved.
Trusted Brands We Service in Mentone
We don’t install generic materials and call them finished. Mentone homeowners get access to the same brand roster we use across San Bernardino County. Roofing systems from GAF and CertainTeed, plumbing fixtures from Grohe and Sterling, countertops from Cambria and Silestone. We stock the common replacement parts locally for faster turnaround on warranty work, and when a roof needs to meet a specific fire rating, we order the exact shingle the spec calls for rather than whatever’s on the shelf. If you’ve done your research and know the brand you want, tell us. We’ll install it and document it.

AfterCommon General Contractor Problems We See in Mentone Homes
- Footings that hit granite without warning. A flat-valley bid doesn’t include rock-breaking, so the contractor hits decomposed granite and boulders mid-dig and the homeowner gets a change order they never saw coming. We write the soil report and rock allowance into the contract before dirt moves.
- Drainage that sends canyon runoff under the foundation. Slopes channel winter rain straight toward downslope homes. Without a swale or a properly graded foundation, the water ends up in the crawlspace or against the stem wall. Every addition we scope includes a drainage plan sized for the actual draw, not a standard detail.
- Non-compliant fire assemblies. A cheap quote often includes standard vents and roofing that don’t meet Mentone’s WUI requirements. The work gets flagged at final inspection and the homeowner pays twice. Ember-resistant venting and the right roof rating are baseline here, not upgrades.
- Missing permit and inspection paperwork. When grading or structural work is done without permits, there’s no sign-off document to show an insurer after a wind or fire claim. We pull the permits, get the inspections, and hand you the paper trail.

FAQs About General Contractor in Mentone
Yes, in most cases. When a hillside addition in Mentone alters drainage, cuts into a slope, or requires a retaining wall over a certain height, San Bernardino County requires a grading permit separate from the building permit. The grading plan documents compaction, drainage, and erosion control. We pull both permits together so the inspection schedule lines up and the homeowner leaves with one clean sign-off package. Call (855) 473-5620 if you want to know whether your specific parcel triggers grading review.
Wind-load requirements push us toward specific nailing patterns, roof deck attachments, and window ratings. Fire ratings, driven by the WUI zone along the canyon mouths, require Class A roofing, ember-resistant venting, and sometimes specific exterior materials. We install GAF and CertainTeed systems rated for this exposure and document the assembly so the compliance is verifiable. A compliant quote includes those line items. A cheap quote usually doesn’t, and the inspector catches it. Call (855) 473-5620 for a quote that includes what the code actually requires here.
Anytime you add bedrooms, and often when you add a bathroom. Septic systems in Mentone are sized for the original house, and adding an ADU or a large addition can push past the approved capacity. The county wants proof the system can handle the load before they’ll approve the permit. We review septic as-builts and well yield early, so the ADU you design is one the county will actually sign off on. Call (855) 473-5620 to talk through your lot before you get attached to a plan.
Rock-breaking allowances, compaction testing, drainage design, permit and inspection fees, fire-rated assemblies, and septic or grading review if the parcel needs them. A cheap bid assumes flat ground and standard materials. On a Mill Creek Canyon-area parcel, that assumption costs you in change orders and failed inspections. We write the real scope from the start. Call (855) 473-5620 and compare our line items to the other quote. The difference is usually the cost of reality.
When you file a claim after a wind or fire event, the insurer asks for proof that the roof, the vents, the windows, and the structural work met the code for the exposure. If the work was never permitted or inspected, you don’t have that proof, and the claim gets harder to win. If it was, you hand over the inspection sign-off and the documentation trail. That’s what we deliver at the end of every Mentone job. Call (855) 473-5620 for an estimate that includes the paperwork, not just the hammer work.
