Fast, Reliable Home Remodeling Across Highgrove
Home remodeling in Highgrove, CA works differently than in a typical incorporated city. Most of the homes here sit on large lots under Riverside County jurisdiction, which means permits, septic setbacks, and grading plans drive both the schedule and the price long before the first wall comes down. We’ve worked these parcels for years, from mid-century ranch houses near Iowa Avenue to newer infill builds off Center Street. When you’re planning a kitchen remodel, a bathroom gut, a garage conversion, or a full home addition in the 92313 ZIP code, call San Mateo Construction at (855) 901-7266. We’ll walk the property, pull the right permit through the right county office, and give you a written quote that actually holds.
Why San Mateo Construction Is Highgrove’s Preferred Home Remodeling Company
Noel Carrington started San Mateo Construction with a simple rule: one contractor answers for every system under the roof, from the foundation to the ridge line. That matters in Highgrove, where a re-roof often happens the same year as a kitchen remodel, and a detached ADU shares the lot with a septic tank that was installed in the 1960s. Our team manages the full scope under one contract: cabinetry, countertops, plumbing fixtures, roofing, windows, siding, hardscape, and the structural work between them. Homeowners don’t chase three different subs and a county inspector. They call one number and get one accountable crew.
We stock or order parts through a supplier network that includes KraftMaid and Wellborn for cabinetry, Cambria and Silestone for countertops, Kohler and Moen for fixtures, and GAF and Owens Corning for roofing. That breadth means a Highgrove homeowner isn’t forced into whatever the local lumberyard happens to carry. We help you choose a material tier that fits the budget, whether that’s a practical Delta shower valve or a Grohe system in the primary bath.
Response time to Highgrove matters. We’re not a crew based two counties away. We’ve run permits through the Riverside County building counter at the Gateway complex in Riverside, and we’ve coordinated with San Bernardino County offices for border parcels. We know the plan check calendars, we know when an inspector will actually show up, and we know how to sequence a remodel so you’re not living in dust for six extra weeks.
Styles & brands we work with







Home Remodeling Contractor in Highgrove
A Home Remodeling Contractor in Highgrove handles the full rebuild of a space: demolition, structural changes, rough-in plumbing and electrical, drywall, finishes, and the final inspection. On a Kentwood Drive kitchen job, that means pulling the Riverside County permit before the cabinets come out. On a large-lot bath remodel near the Box Springs foothills, it means locating the old cast-iron drain line before we set the new shower pan. Highgrove kitchen remodels typically run $14,000 – $45,000, and bathrooms run $9,000 – $28,000. The wide range reflects what’s behind the walls, not just the finish choices.
Whole-home scope on acreage parcels
Many Highgrove properties include outbuildings, older additions, or attached garages that were permitted decades ago under county rules that no longer exist. We scope the entire parcel before quoting: the house, the detached garage, any future ADU pad, and the trench path for updated electrical or gas service. That way the number we give you covers the whole job.
Working with unincorporated lot conditions
Highgrove has no city building counter. Everything routes through Riverside County, with San Bernardino County involved when the parcel sits near a boundary. We confirm which office holds the permit before we submit plans, and we flag any well or septic setback that could push a foundation or force a drainfield redesign.
Home Remodeling Companies in Highgrove
Most Home Remodeling Companies serving Highgrove are actually based in Riverside, San Bernardino, or farther west. A few are one-truck operations that sub out every trade. What separates a good fit from a costly mistake is whether the company has worked unincorporated county parcels before. A company that assumes a city permit counter will lose weeks on a Highgrove job. A company that doesn’t ask about the septic tank location before quoting a detached ADU will hit you with a change order. Ask the question. Then ask it again.
We’ve remodeled homes on large lots where the original survey stakes are gone, where the leach field runs diagonally across what you assumed was the buildable pad, and where the driveway is a quarter-mile of gravel that a concrete truck has to navigate in August heat. That’s just Highgrove. It’s not harder; it’s different. You need a contractor who knows the difference.
Single-contract accountability
When the same general contractor who re-roofs the house also remodels the kitchen, the scheduling actually works. The roofer doesn’t wait on the framer. The framer doesn’t blame the plumber. We carry the schedule end to end, and every sub answers to us.
Written allowances, not verbal ballparks
We write material allowances into the contract, line by line. KraftMaid cabinet line, Cambria slab color, Kohler fixture model. That keeps the budget honest and gives you a real selection to make, not a surprise bill at the end.
Trusted Brands We Service in Highgrove
Window and door replacement on a Highgrove home often means swapping old single-pane aluminum for units that meet current Title 24 energy standards. We work with Therma-Tru entry doors, ViewLux and ECO Window Systems for replacement windows, and Mr-Glass for glass packages on doors and sidelights. Because we order from these suppliers regularly, turnaround for Highgrove jobs stays tight. We’re not waiting on a distributor in another region to ship a single door slab. Parts arrive, we schedule the install, and you’re back to normal life.
Common Home Remodeling Problems We See in Highgrove Homes
- Permit confusion at the county line. A remodel on a border parcel can draw both Riverside and San Bernardino County review. We confirm the governing authority before we submit anything, and we build the plan check time into the schedule.
- Septic and well setbacks that kill a footprint. On acreage off Iowa Avenue, we’ve seen leach fields run exactly where a homeowner hoped to pour an ADU slab. Locating the tank and leach lines first prevents a six-week delay and a re-drawn site plan.
- Long material hauls and tight access. Gravel drives and narrow easements slow delivery trucks and equipment staging. We price the haul realistically up front so it doesn’t surface later as a change order.
- Old mid-century wiring and cast iron drains. Many Highgrove homes date to the 1950s and 1960s. Opening a wall for new cabinets often reveals knob-and-tube or a drain line ready to fail. We inspect before we quote, and we show you photos of what we found.

AfterPricing for Home Remodeling in Highgrove, CA
Here are the ranges we quote most often for Highgrove work. Your exact number depends on square footage, material tier, and what the county requires, but these figures are calibrated to this market.
| Service | Highgrove Price Range |
|---|---|
| Kitchen Remodel | $14,000 – $45,000 |
| Bathroom Remodel | $9,000 – $28,000 |
| Home Addition | $45,000 – $130,000 |
| ADU Construction | $90,000 – $220,000 |
| Garage Conversion | $30,000 – $80,000 |
| Cabinet Installation | $4,000 – $13,000 |
| Countertop Installation | $2,000 – $6,500 |
| Walk-In Shower Installation | $4,500 – $12,000 |
What moves the number? For a kitchen, a full gut with structural headers and updated electrical pushes toward the top. A cabinet and countertop refresh stays low. Same logic for a bath: a tub-to-shower conversion with Schluter waterproofing and a new valve costs less than moving a drain line. On any Highgrove property, the first thing we do is walk the lot, pull the county records, and check the septic and well locations. Then the quote means something. Call (855) 901-7266 for a free estimate on your specific project.
Why Highgrove’s County Permitting Changes What You’ll Pay
Highgrove is an unincorporated Riverside County island ringed by incorporated San Bernardino County. There is no city building counter in 92313. Every permit, inspection, and plan check routes through a county office, and a lot near the boundary can draw both counties’ attention. That single fact changes what a homeowner should demand from any contractor’s quote. A set of plans that ignores the governing county is a plan that gets rejected. A schedule that assumes a one-week plan check is fiction. On a large-lot property off Iowa Avenue, we remodeled a mid-century kitchen and added a detached shop. The first order of business was confirming the existing septic tank and leach field locations before we set any footing or trench for utilities. Our crew kept the shop’s rough-in clear of the well setback, pulled the Riverside County permits before demolition, and nailed down finishes like KraftMaid cabinets and a Cambria countertop through written allowances so the budget held. At the punch list, the inspector signed off on the revised load-bearing header and the new subfloor in one visit. That’s how a Highgrove job has to run.
If you’re planning an Home Remodeling project on one of these county parcels, the estimate has to reflect real site conditions. A generic quote from a city contractor won’t. We scope the setbacks, the haul distance, the grading, and the drainage before we put a number in front of you.
Serving Home Remodeling in Highgrove isn’t just about swinging hammers. It’s about knowing which county office signs off and how long that takes.

FAQs About Home Remodeling in Highgrove
Riverside County issues permits for most Highgrove parcels, since the community is unincorporated. If your lot sits near a boundary with an incorporated city like Grand Terrace or Colton, San Bernardino County may hold jurisdiction for certain aspects. We verify the governing authority before we submit anything, and we handle the plan check and inspection calendar from there. Call (855) 901-7266 and we’ll check your specific parcel for free.
Yes. A detached ADU or shop cannot be set on top of a septic tank or leach field, and Riverside County enforces well setbacks strictly. We locate the existing system before we draw the site plan. That keeps the footing, the rough-in, and the final inspection from failing. For an exact scope on your Highgrove lot, call us at (855) 901-7266.
Long gravel drives and narrow access paths slow trucks, require smaller delivery vehicles, and add staging time. A concrete truck that can dump at the curb in Colton may need to be scheduled differently on a half-mile Highgrove driveway. We price that haul line up front so it doesn’t appear later as an extra. Get a written quote with delivery included by calling (855) 901-7266.
We grade the pad and surrounding grade to shed water away from the new foundation, and we tie any roof drainage into a plan that won’t flood the neighbor’s fence line or your own well area. On open lots, that often means a swale or a French drain added to the scope before framing starts. Call (855) 901-7266 for a free drainage assessment with your remodel estimate.
Written allowances, a pre-quote site walk, and permit verification before contract signing. We write every cabinet line, countertop slab, and fixture model into the contract. We locate the septic and well on day one. We confirm the governing county before we file. When those three things are done up front, the price holds. Schedule your free estimate at (855) 901-7266.
