Fast, Reliable General Contractor Across Mentone
Most of Mentone is unincorporated San Bernardino County, which means your addition, ADU, or garage conversion doesn’t run through a city building department. It runs through County Land Use Services, and the difference matters more than most homeowners realize. We’re Moreno Valley Builders, a full-scope General Contractor team that manages the county permit path, the crafton-slope soils reality, and the wind-rated product documentation in one scope of work. If you’re planning a project in the 92359, call (877) 752-3154 for a free estimate before you sign anything.
Why Moreno Valley Builders Is Mentone’s Preferred General Contractor Company
We know what a dig on the crafton slopes does to a footing budget because we’ve done it. Decomposed granite and boulders show up mid-excavation and the county inspector wants a revised load-bearing detail before the pour. That’s not a surprise to us anymore. It’s a line item we plan for. Homeowners across Mentone Boulevard, the old town center, and the rural county parcels have called us for additions, ADUs, and outbuilding conversions because we sequence the permit, the re-engineered footing, and the scheduling so the draw schedule doesn’t stall.
Our team works with 50+ name-brand manufacturers, which means your Mentone project gets real material choices, not builder-grade defaults. GAF and CertainTeed roofing, PGT impact windows, Belgard pavers for hillside patios and driveways. You pick. We specify, permit, install, and stand behind the work through final inspection.
Styles & brands we work with
Residential General Contractor in Mentone
A residential general contractor in Mentone handles the full project lifecycle: permit submittal through San Bernardino County Land Use Services, demolition, foundation and framing, rough-in for plumbing and electrical, roofing and windows (wind-rated for Santa Ana events), and final inspection sign-off. Homeowners in Mentone typically hire us for home additions, ADU construction, garage conversions, and whole-home remodels on early-to-mid 1900s ranch and Craftsman homes or scattered custom hillside builds.
County-Permit Project Management
Noel Trevino leads our project management, and he’s built the sequencing around how the County actually works in Mentone. Erosion control before winter. Grading approvals before the dig. Footing revisions documented before the inspector arrives. A home addition in Mentone runs $45,000 to $130,000, and the difference between a smooth job and a stalled one is whether the contractor planned for the county’s review rhythm.
Single-Contractor Accountability
One contractor. Every phase. You don’t juggle a roofer, a glazing crew, a concrete sub, and a cabinet installer. We coordinate all of it, including the brands you select for each trade. Your project. Your material choices. From permits to punch list, the whole thing funnels through our schedule.
Hire a General Contractor in Mentone
Hire a General Contractor in Mentone when your project touches structure: load-bearing wall removal, a second-story addition on a canyon slope, a detached ADU on a rural parcel, a roof replacement that has to hold wind-rated shingles and underlayment. These are not handyman scopes. The county inspector will ask for engineering, and the insurance carrier will ask for documentation. We provide both.
Slope, Soils, and Footing Reality
On a hillside addition off the crafton-area slopes above Mill Creek Canyon, our crew dug footings and hit boulders and decomposed granite that forced a revised load-bearing footing detail and a change order before the County inspector would sign off. We kept the concrete and framing schedule on the draw schedule by sequencing the re-engineered footings around winter-storm erosion control, then finished the rough-in and punch list before the wet season hit the canyon. That’s the Mentone job, and it’s why we don’t quote from a national cost book.
What a Compliant Quote Contains
A compliant Mentone quote includes the soils report or grading note, the wind-load spec on the roof covering and any impact glazing, and the permit line item through County Land Use Services. If a bid leaves those out, it’s cheap on paper and expensive after excavation. ADU construction in Mentone runs $90,000 to $220,000. A garage conversion runs $30,000 to $80,000. The range reflects whether the scope accounts for the actual ground you’re building on.
Trusted Brands We Service in Mentone
We specify Belgard for hillside patios and retaining areas because their paver lines hold up against the wet-dry swing of Mentone winters and summers. We carry Unilock product access for driveways and courtyard work where the decomposed granite grading wants a well-drained base. For fencing on rural county parcels, ActiveYards gives us aluminum lines that won’t warp in the dry heat the way lesser metal does. We stock and order local for Mentone projects, so when a material spec changes after the dig, we’re not waiting two weeks for a truck from out of state.

AfterCommon General Contractor Problems We See in Mentone Homes
- Footings that didn’t plan for decomposed granite. The crafton slopes sit on decomposed granite and boulders, and the flat valley floor along Mentone Boulevard is underlain by sandy alluvial wash. A footing that isn’t engineered for that ground changes price mid-dig, and the county inspector won’t sign off until it’s right.
- Roof coverings and glazing that aren’t wind-rated. Santa Ana events off the San Bernardino Mountains push wind hard through the canyon. If the shingle spec or window rating isn’t in the written scope, the insurance claim gets denied later.
- Unpermitted outbuilding work on rural parcels. Mentone has detached workshops and outbuildings on unincorporated county land. Unpermitted conversions surface at resale and kill the sale. We pull the county permit and get the inspection sign-off.
- Drainage and erosion control treated as an afterthought. Winter storms funnel heavy rain down Mill Creek and the canyon washes. A project without a drainage plan erodes, and the county will halt it. We build erosion control into the construction sequence, not the punch list.

The gap between the low and high end is rarely about finish quality alone. In Mentone it’s about whether the quote accounts for county permit timing, slope grading, and wind-rated materials. A $45,000 addition on flat alluvial soil is a different job than a $130,000 addition on decomposed granite with a retaining wall. We quote it honestly.

FAQs About General Contractor in Mentone
Most of Mentone is unincorporated San Bernardino County, so your addition permit goes through County Land Use Services, not a city building department. Setbacks, grading, and sign-offs all run through the county. We handle that path from submittal through final inspection. Call (877) 752-3154 if you’re not sure which jurisdiction your parcel falls under.
Because the crafton slopes are decomposed granite with embedded boulders, and the footing design often has to be re-engineered once excavation exposes what’s actually down there. We plan for a revised load-bearing detail in our initial quote rather than springing it later. It changes the price. It shouldn’t change the trust.
A compliant Mentone quote should name the roof covering spec and any impact glazing rating, tied to the wind-load requirements for Santa Ana events off the San Bernardino Mountains. If the written scope doesn’t include that documentation, the work may not support an insurance claim later. We put the rated products in writing before we start.
Line-item the county permit, the soils and grading scope, and the wind-rated material specs. A low bid that omits those will balloon after excavation or fail inspection. Ours includes them. We would rather be the higher-priced bid with a realistic scope than the cheap one that stalls at the dig.
Yes. Rural county parcels with detached workshops and outbuildings are common in Mentone, and we convert them to ADUs or livable space with the county permit pulled properly. Unpermitted outbuilding work surfaces at resale, and a conversion without county sign-off is a liability. Call (877) 752-3154 for a site walk and a real number.
