Penhallow Remodeling Riverside serves homeowners across Highland with kitchen remodels, bathroom remodels, room additions, and whole-home renovations, and we coordinate every job from our Inland Empire office. A live person answers our phone around the clock, so when you call (341) 895-1170, you get a real answer, not a voicemail maze.

Why Penhallow Remodeling Riverside Is Highland’s Preferred General Contractor Company
Highland homeowners have plenty of reasons to be skeptical of contractors. Many have been burned by a verbal estimate that doubled after demo day, or a repair that failed six weeks later with no one answering the phone. We built our entire process around fixing that. Every project gets a written price up front, a defined arrival window, and the 365-Day Done Right Promise: if something fails inside the guarantee period, we come back and fix it at no charge. That’s not a slogan. It’s in writing on every job.
Our crews know Highland’s terrain. We deal with the same conditions you do: Santa Ana winds, hot summer-afternoon sun on east-facing walls, and clay soil that moves more than it should. When we scope a foundation repair or a hillside retaining wall, we’re looking at the actual soil on your lot, not a generic template. Our technicians are background-checked and uniformed, so the person who walks through your door is someone we’d send to our own kitchen table.
We’re part of the Kingswell family of companies and have operated under The Kingswell Way since 2004. Each location is independently owned and operated, which means our Highland customers get local accountability backed by a national standard. Trevor Nash leads our team, and he built our reputation on saying the price before the work and standing behind it after.
Styles & brands we work with
Construction Company in Highland
A construction company in Highland does more than swing hammers. Here, building on acreage means county permitting, septic and well setbacks, fire-safe grading, and material hauls that can add real cost if nobody planned for them. Whether you’re adding a detached workshop, a garage conversion, or a full ADU, the job starts with the paperwork and the ground itself. In Highland, a home addition typically runs $45,000 – $130,000, a garage conversion $30,000 – $80,000, and an ADU $90,000 – $220,000. Those are real ranges, not placeholders.
County Permitting and Setbacks
Because much of Highland’s acreage lies in unincorporated San Bernardino County, projects outside city limits require county permits that city-only contractors may never touch. We check septic and well setback requirements before we quote, so you don’t get a stop-work notice three weeks into framing.
Grading and Drainage on Open Lots
Highland’s expansive clay soil is a real thing. It swells when wet and shrinks when dry, which cracks slabs and shifts retaining walls. On open acreage, we scope grading and drainage first, because ignoring it is the most common way a Highland project goes over budget and off schedule.
Remodeling Contractor in Highland
A remodeling contractor in Highland is working with homes built from the 1960s onward: ranch-style and two-story tract homes, many with slab-on-grade foundations and original cast iron plumbing. That plumbing is usually at the end of its life if it has not already been replaced. When you’re remodeling a kitchen or bathroom, the work often expands to include trenchless pipe repair or full repiping once we open the walls and see what’s actually there. A kitchen remodel in Highland runs $14,000 – $45,000, and a small kitchen can be done for $9,000 – $20,000. Bathrooms run $9,000 – $28,000, with small baths at $5,000 – $12,000.
Written Price Before We Start
We give you a written number before any work begins. Not a range on a napkin. When you sign, the invoice matches the quote unless you request a change order, and we walk you through any change before it happens.
The Kingswell Way
Say the price before the work. Show up in the window we gave. Leave the place cleaner than we found it. That’s the operating standard we’ve followed since 2004, and it’s why our Highland customers keep calling back.
Trusted Brands We Service in Highland
We install materials that carry their own warranties alongside ours. That includes Cambria and Silestone quartz countertops, KraftMaid cabinetry, Kohler and Moen fixtures, and James Hardie siding. For outdoor work, we use Belgard and Techo-Bloc pavers with the same written guarantee. Highland homeowners get the same product availability as our Inland Empire customers, and because we plan material deliveries around long hauls, your project is not sitting idle waiting on a truck from two counties over.
Common General Contractor Problems We See in Highland Homes
- Underestimated grading on open lots: A homeowner builds on acreage, skips proper drainage, and the slab cracks after the first heavy winter rains. We scope grading before quoting, because we’ve seen how expensive a cracked slab gets.
- Skipped septic and well setback checks: County rules on septic and well clearances can stop a permitted project for weeks if nobody checked them first. We pull those records during planning, not after you have already paid for materials.
- Material hauls that blow the budget: Remote acreage in East Highlands means longer delivery routes and more equipment moves. If a contractor quotes without accounting for that, the budget is fiction. We build real haul costs into the written price.
- Original cast iron plumbing failures: Homes from the 1960s and 1970s still have cast iron waste lines. Once we open a wall during a remodel, that pipe often needs replacement, and we tell you what that costs before we touch it.

FAQs About General Contractor in Highland
Yes. Most detached structures on unincorporated Highland acreage require San Bernardino County permits, and setback rules differ from city limits. We pull the county records and confirm septic and well clearances before we quote, so you’re not waiting on a stop-work order. Call (341) 895-1170 and we’ll tell you exactly what your lot needs.
Expansive clay swells and shrinks with moisture, which causes slab cracking and retaining wall movement. Your quote will include drainage corrections and possibly deeper footings, because repairing a slab without fixing the drainage under it means you’ll be repairing it again. We scope the soil before we price the fix, and the number you get is the number you’ll pay.
San Bernardino County requires defensible space, fire-resistant materials, and specific grading for new construction in the foothills. We handle those requirements as part of the permit package rather than letting them surprise you mid-project. Call us for a written estimate that includes fire-safe grading from day one.
Yes, they can. Deliveries to East Highlands and other outlying acreage take longer and cost more than jobs near main corridors, and equipment moves add up. We build those haul costs into the written price up front, so the quote is real and the invoice matches it.
That depends on the septic system’s capacity and clearance. San Bernardino County requires septic and well setbacks to be verified before an ADU conversion permit will be issued, and some existing systems need expansion. We check those records before quoting, so you know whether the conversion is feasible and what it will really cost. Call (341) 895-1170 for a free estimate.
Building on Highland Acreage: The Local Playbook
Because most of Highland’s acreage lies in unincorporated San Bernardino County, our general contractor work here often requires county permits, septic and well setbacks, and fire-safe grading that city-only contractors never deal with. That’s not a sidebar detail. It’s the difference between a project that stays on schedule and one that stops for weeks while the owner discovers they built in the wrong place. Out in East Highlands, we rebuilt a hillside home’s retaining wall after expansive clay caused the old one to tilt and crack the slab. Our crew re-graded the slope with a proper drainage swale, poured a new reinforced wall, and used a change order to upgrade the footing depth once we hit unexpected debris-flow debris. The owner now has an inspection sign-off and a stable foundation through the next rainy season. That’s the kind of thing you only learn by doing the work here, not by reading a spec sheet.
If you’re planning construction on Highland acreage, the first step is a written quote that accounts for county permitting, septic and well setbacks, grading, and haul costs. You can see how we approach the broader scope of our work on our General Contractor in Highland page. Or call (341) 895-1170 to get a real number for your specific lot.
