Why Penhallow Remodeling Is Highland’s Preferred General Contractor Company
Highland homeowners have told us the same stories for years: the contractor who vanished after demo, the verbal estimate that doubled at invoice time, the tile that cracked six weeks after the crew left. We built our entire process to be the opposite of that. Every project starts with a written price, a defined arrival window, and a written 365-Day Done Right Promise. If something fails inside that year, we come back and fix it at no charge. No re-inspection fee, no service call, no argument.
Trevor Nash leads our Highland projects. He’s the one who walks your property with you, explains what “cripple-wall bracing” means in plain English, and tells you honestly when a geotechnical report is going to add two weeks and $4,000 to the front of a job. That candor is why Highland homeowners keep our number saved. Our background-checked, uniformed technicians show up on time and leave the site cleaner than they found it. And yes, a live person answers when you call, 24/7.
Residential General Contractor in Highland
Residential General Contractor work in Highland covers the full scope of a home remodel or addition: structural framing, foundation work, plumbing and electrical rough-in, drywall, cabinetry, tile, flooring, and finish carpentry. Homeowners here call us when a kitchen has outlived its layout, a bathroom needs a walk-in shower conversion, or a growing family needs another bedroom. A General Contractor in Highland has to understand the local permit process, because the city’s foothill zones layer seismic and fire requirements on top of standard California building code. We handle all of that, from engineered plans to final inspection sign-off.
Kitchen Remodeling in Highland typically runs $14,000 – $45,000 depending on cabinet line, countertop material, and whether you’re moving plumbing. Bathroom remodels land between $9,000 – $28,000, with smaller baths starting around $5,000. Whole-home remodels are usually priced per square foot after we walk the property and pull the necessary reports. The number we give you before work starts is the number on your final invoice. That’s simply how we operate.
Written Scope, Permits, and Inspections
We pull all required permits for Highland projects and schedule every inspection. If you’re in the foothill areas above 5th Street, that often includes a geotechnical boring report and Chapter 7A fire-compliance documentation. We submit those with the permit package so there are no surprises at inspection time.
Fixed-Price Remodeling, Not Ballparks
We don’t give ranges with a shrug. We walk the property, pull reports where needed, price the actual scope, and hand you a written number you can hold us to. If something changes because you add scope, we price the change order in writing before we do it. You approve it first. Always.
Hire a General Contractor in Highland
When you hire a general contractor in Highland, you’re hiring someone to manage the entire project: permits, subcontractors, material deliveries, inspections, and the schedule. That’s the job. What Highland homeowners actually need is someone who understands the city’s unique geotechnical and fire-safety landscape before they price the work. We’ve pulled enough permits near Base Line Road and Highland Avenue to know which projects trigger extra engineering and which ones clear prescriptive code. That local knowledge is the difference between a clean permit and a stalled job.
Room additions in Highland typically run $45,000 – $130,000, depending on whether the addition is on a slab or requires new foundation engineering. Garage conversions run $30,000 – $80,000, and an ADU in the foothills can range from $90,000 – $220,000 once the site work, fire compliance, and seismic detailing are factored in. We walk you through every line item. You’ll understand where each dollar goes before you sign anything.
Seismic and WUI-Compliant Additions
Additions in Highland north of 5th Street routinely need engineered foundations because of the alluvial fan and the proximity to the San Andreas Fault system. We bring in a geotechnical engineer when the scope warrants it, and we include the boring report cost in your written price up front. You should never get a change order mid-excavation because the contractor didn’t know what was under the soil.
The 365-Day Done Right Promise
Every Highland project includes our written guarantee: if the work fails inside 365 days, we come back and fix it. Free. That includes the second visit if a repair fails. We put it in writing on every job, no matter the size.
Trusted Brands We Service in Highland
We source materials from brands that carry their own warranties alongside ours, so Highland homeowners get layered protection. For cabinetry we use KraftMaid and Wellborn. Countertops come from Cambria, Silestone, and Caesarstone. Fixtures are Kohler, Moen, and Delta. Siding and roofing that meet Chapter 7A fire-resistance requirements are sourced from James Hardie and others we trust. For projects involving alternative building methods, we’ve worked with systems from Dvele and Cover, and Sakrete products for concrete and masonry. We order locally and coordinate deliveries around Highland’s specific inspection schedule, so materials don’t sit on your driveway longer than they have to.
Common General Contractor Problems We See in Highland Homes
- Non-compliant WUI materials in foothill remodels. We’ve walked into homes above 5th Street where a previous contractor installed roofing or vents that didn’t meet Chapter 7A fire requirements. The fire inspection failed, and the homeowner had to pay us to tear out and replace materials that should have been code-compliant from day one.
- Foundation pricing without a geotechnical report. On additions and deep excavations in the northern tracts, hitting remobilized debris-flow deposits adds cost and engineering. A contractor who prices without a boring report will hit you with a change order the moment the excavation finds boulder-laced sediment. We pull the report before we price the scope.
- Skipped seismic detailing on slab homes from the 1950s – 1980s. Highland’s housing stock is mostly slab-on-grade tract homes sitting on expansive alluvial soil. Many need cripple-wall bracing and anchor-bolt retrofits to meet current California seismic standards. A cheap quote that ignores this won’t clear inspection and can complicate an insurance claim later.
- Thermal-cycling damage to stucco and roofing underlayment. Summer temperatures in Highland regularly exceed 105°F, which accelerates crack formation in stucco and degrades roofing underlayment faster than in coastal markets. We see homes where the previous repair simply didn’t account for that level of thermal cycling, and the cracks were back within a year.

A home addition north of 5th Street almost always needs a boring report, and the engineering that follows adds thousands to the front of the job. That’s not padding. It’s what keeps the foundation stable on alluvial soil, clears inspection, and keeps your homeowner’s insurance valid. We’ll show you every line item. Call (936) 259-2607 for a free written estimate.

FAQs About General Contractor in Highland
If your home is north of 5th Street or sits on the alluvial fan below the San Bernardino Mountains, the answer is almost always yes. The city routinely reviews foundation and addition plans for WUI Chapter 7A compliance and a geotechnical report is effectively mandatory because of remobilized debris-flow deposits, loose boulder-laced sediment layers left by post-wildfire storm events. We include the boring report cost in our written estimate before you sign. Call (936) 259-2607 and we’ll tell you honestly whether your specific lot needs one.
Chapter 7A is California’s Wildland-Urban Interface building code, and it applies to many Highland homes in the northern foothills. It requires Class A roofing, ember-resistant vents, ignition-resistant siding, and specific eave and soffit details that slow a fire’s spread. If your remodel or roof replacement falls in a WUI zone, we spec and install code-compliant materials from the start, so you don’t fail a fire inspection and have to pay for tear-out and replacement. Call (936) 259-2607 for a free estimate on a compliant roof replacement.
Documented compliance helps on both fronts. When you file a claim after a seismic event or storm damage, your insurer will look for proof the work met current code. Engineered foundations, cripple-wall bracing, anchor-bolt retrofits, and Chapter 7A materials all need to be documented on the permit and inspection record. A contractor who skipped those to save money leaves you holding a denied or reduced claim. We document everything, and we give you the paperwork. That record also matters if you sell: buyers increasingly ask for retrofit documentation on Highland homes.
A written price, a defined arrival window, the full scope of work, the permit plan, the inspection schedule, the brand and grade of every material, and a written workmanship warranty. That’s what we provide on every Highland project, along with the 365-Day Done Right Promise. We were called to a mid-century wood-frame home near Base Line Road where the owners wanted a room addition; before we priced the scope of work, we pulled a geotech and found the slab was already showing differential movement on alluvial soil, so we added engineered cripple-wall bracing and anchor-bolt retrofits into the rough-in. The same job in a Fontana flatland tract would have been a standard stem-wall addition. That Highland home sits in the shadow of the San Bernardino Mountains where post-fire debris flows have left boulder-laced sediment, so the engineered foundation was not optional, it was what let the permit clear inspection sign-off and stay insurable. Call (936) 259-2607 before you sign any other estimate.
Because in Highland’s foothill-adjacent neighborhoods, the soil conditions and seismic triggers demand more engineering. Contractors working on additions or deep excavations north of 5th Street routinely hit remobilized debris-flow deposits, loose sediment packed with boulders carried down by post-wildfire storms from the San Bernardino Mountains. A geotechnical boring report becomes mandatory before pricing foundation work, and the engineered solution costs more than standard prescriptive code. Fontana and Colton sit on flatter, more predictable soil and rarely trigger that level of review. You’re not paying for a contractor’s comfort. You’re paying for a foundation that won’t fail on that soil. Call (936) 259-2607 for a written estimate that includes the full engineering scope up front.
