Fast, Reliable General Contractor Across Highland
Most Highland remodels run $14,000 to $45,000 for a kitchen, $9,000 to $28,000 for a bathroom, and $45,000 to $130,000 for a home addition, depending on how far the work goes once walls are open. San Bernardino Contractors is a full-service General Contractor team led by Ruben Castillo, serving Highland from Fontana with same-week site visits and written, line-item estimates. We know Highland’s mid-century tract homes, the stucco and tile roofs, the slab foundations, and what it takes to bring an older Inland Empire house up to current code without blowing the budget. Call (855) 473-5620 to schedule a free estimate. We’ll walk the property with you, not just quote over the phone.
Why San Bernardino Contractors Is Highland’s Preferred General Contractor Company
Highland homeowners call us because we show up with a construction plan, not a sales pitch. Ruben Castillo has built this company around one idea: one contractor, every phase. That means when we open a kitchen wall on a 1960s tract home near Baseline and find aluminum branch wiring, we don’t stop and call an electrician you’ve never met. We handle it. We price it. We pull the permit. And we don’t ask you to manage the schedule.
Our reputation in Highland is built on that single-point accountability. Homeowners here have dealt with the subcontractor shuffle: a roofer who blames the window crew, a window crew who blames the framing. With San Bernardino Contractors, there’s no finger-pointing because there’s no one to point at except us. The same crew that specs your James Hardie siding also coordinates the stucco match on the gable end and the flashing detail where the patio cover ties in.
We respond to Highland calls from Fontana quickly, typically scheduling initial walkthroughs within the same week. We’ve worked homes along Greenspot Road, through the neighborhoods south of Highland Avenue, and up into the foothill lots off Weaver Street. That local familiarity means we know what the building department will flag, what the soil does under a slab in this part of the valley, and which materials hold up to the dust and heat.

General Contractor Services in Highland
General Contractor Services in Highland cover the full scope of residential work, from kitchens and bathrooms to roofs, windows, fencing, hardscaping, and ADU construction. When a Highland homeowner calls us, it’s usually because a project spans multiple trades and they want one accountable team, not three separate contracts. A whole-home remodel here typically runs $45,000 to $130,000, while a single kitchen starts around $14,000 and a bathroom around $9,000.
Remodel Planning and Pre-Bid Inspection
Before we quote anything, we walk your home and look at what’s actually inside the walls. In Highland’s mid-century tracts, that often means aluminum branch wiring, original plumbing, and framing that was fine in 1962 but won’t pass a load check today. We write allowances for electrical, framing, and waterproofing upgrades directly into the contract so you don’t get ambushed later.

Permit Coordination and Code Upgrades
Opening walls in a Highland home triggers code requirements: GFCI protection, hardwired smoke detectors, sometimes lateral bracing. We pull permits from the city, schedule inspections, and price any mandatory upgrades before work starts. Surprises still happen in remodeling, but a missed permit doesn’t have to be one of them.

Construction Company in Highland
As a Construction Company serving Highland, we take projects that most remodelers won’t touch: room additions, ADU construction, garage conversions, and full exterior overhauls alongside interior remodels. A room addition in Highland runs $45,000 to $130,000. An ADU starts around $90,000 and can exceed $220,000 depending on size, finish level, and site work. The cost reflects what’s actually involved: foundation work on slab lots, new electrical service, roofing tie-ins, and Highland’s heat-driven material requirements.
Additions and ADU Construction
Highland’s ranch-style and Spanish-colonial lots were designed decades before ADU laws. Most have the footprint for a detached unit, but not the electrical service. We handle the panel upgrade, the grading, the concrete, and the prefab or site-built structure. We work with Abodu, Dvele, Plant Prefab, and Boxabl for homeowners who want a faster, cleaner build process.
Exterior and Site Work
From the roof down to the pavers, we handle exterior work in-house. Roof replacement in Highland runs $8,000 to $20,000, window replacement $4,500 to $15,000, and paver patios $3,500 to $11,000. We spec materials for Highland’s climate: heat-resistant shingles, impact-rated windows where wind-blown debris is a concern, and pavers that won’t shift in the dry, expansive soil.
Trusted Brands We Service in Highland
You pick the brand, we handle the build. We’re authorized to work with GAF and CertainTeed roofing systems, Grohe and Sterling plumbing fixtures, and a roster of 50+ manufacturers across cabinetry, countertops, windows, and hardscaping. That matters in Highland because your house shouldn’t be limited to whatever the contractor has in the warehouse. We specify materials for the heat and wind conditions here: GAF shingles with higher reflectivity for east-facing roofs, CertainTeed siding that holds color under constant sun. If a manufacturer’s warranty ever needs a repair, we’re authorized to perform the work, no warranty runaround.

AfterCommon General Contractor Problems We See in Highland Homes
- Aluminum branch wiring behind drywall. Mid-century Highland tract homes were built with aluminum branch circuits, which oxidize over time and create fire risk at connections. We price the re-wire or pigtail remediation upfront, so it doesn’t become a mid-project change order.
- Failed waterproofing on stucco exteriors. Highland’s dry heat cracks stucco, then the rare heavy rain gets behind it and rots the sheathing. We inspect for moisture damage before quoting exterior work, because painting over rot wastes your money.
- Undersized framing for modern door and window openings. Older Highland homes have headers sized for the original single-pane windows. Widening an opening, even for a slider or French door, often requires a structural upgrade. We check the load path before we cut anything.
- Heat-gain issues on east-facing foothill lots. Homes on the east side of Highland get direct morning sun that cooks west-facing interiors by afternoon. We rotate window placements and spec heat-reflective finishes to cut the glare and the cooling bill, a detail builders from San Bernardino or Redlands often miss.

FAQs About General Contractor in Highland
Expect aluminum branch wiring, original galvanized plumbing, and framing that may not pass today’s load-bearing checks. We do a pre-bid inspection and write allowances for electrical, framing, and waterproofing upgrades into the contract so these line items are visible before the hammer comes out. Call (855) 473-5620 to set up your inspection.
We write allowances into the contract for exactly these issues, then price any actual discovery in a signed change order before we touch the affected area. You approve the number first. No rushed markups, no mid-project shutdowns. That’s how we handle the surprises that Highland’s older homes routinely deliver.
Yes. East-facing foothill lots in Highland get brutal morning sun, so we rotate window placements to reduce west-side heat gain and spec heat-reflective finishes where it matters: cool-roof shingles from GAF, lighter paver colors from Belgard, and window glass with solar control coatings. Most contractors from San Bernardino or Redlands never think about it because their lots don’t sit the same way.
We sequence openings carefully and keep temporary dust barriers in place whenever the Santa Anas kick up, which they do regularly in Highland. Dry, dusty wind gets behind plastic sheeting and into fresh drywall mud and paint, so we schedule exterior work around the forecast and seal interior work zones before we cut exterior openings.
First we survey the site and check the existing foundation, electrical service, and roof tie-in. Then we pull permits from the city, pour the slab or footings, frame, roof, and tie into the existing house before finishing the interior. A room addition in Highland typically runs $45,000 to $130,000. Call (855) 473-5620 and we’ll walk the property before you commit to anything.
