Highgrove sits at the foot of the Box Springs Mountains, and that location shapes nearly every project we take on here. Lots are older, often larger, and frequently graded decades ago when drainage and retaining wall standards were different. We plan for what walls and subfloors will reveal, because in this market, surprises are predictable if you know the housing stock. Ken Stafford, owner at Milpitas Construction, built our process around that reality: inspect first, write allowances in writing, and price every change order before work proceeds.

Key takeaways:

• A kitchen remodel in Highgrove typically runs $14,000 – $45,000 depending on scope and what the walls reveal.
• Bathroom remodels range $9,000 – $28,000, with walk-in showers and tub-to-shower conversions on the lower end of that bracket.
• ADU construction runs $90,000 – $220,000, and we handle prefab options from Abodu, Dvele, and Boxabl.
• Roof replacement on an older Highgrove home runs $8,000 – $20,000, with Santa Ana wind uplift factored into the spec.
• Free estimates, written line-item quotes, and fixed pricing with no change orders unless you approve them in writing first.

Why Milpitas Construction Is Highgrove’s Preferred General Contractor Company

The reason homeowners in Highgrove call us is simple: we spec materials by name and we write allowances into the contract before demolition starts. Too many projects in this area stall when a contractor opens a wall, finds undersized framing or a failed waterproofing pan, and calls it “unforeseen.” We don’t work that way. We inspect attics, crawl spaces, and subfloors during the estimating phase, so the quote reflects what the house will actually require.

Highgrove’s hillside and canyon-edge parcels introduce variables flat-land neighborhoods in Riverside never see. Graded pads settle. Retaining walls built in the 1970s crack. Pierce-and-beam foundations move through decades of dry-season expansion. We walk every project with that context, and it shows in how we write contracts and manage permits. When the county inspector signs off on a rough-in before a wall closes, you’re not guessing about what’s behind the drywall.

Ken Stafford leads every project with the same approach: one accountable team, from the roofline to the kitchen counter, with material choices drawn from 50+ brand-name product lines. That means KraftMaid or Wellborn cabinetry, Cambria or Caesarstone counters, Kohler and Grohe fixtures, and GAF or CertainTeed roofing, all selected with you, not for you.

Residential General Contractor in Highgrove

A residential general contractor in Highgrove takes a remodeling or addition project from planning and permits through demolition, rough-in, finish work, and final inspection. Older homes in 92313, most built mid-century with wood framing and original slab or pier-and-beam foundations, almost always need electrical, plumbing, or structural upgrades once walls are open. A full kitchen remodel here runs $14,000 – $45,000, and a bathroom remodel runs $9,000 – $28,000. The numbers move based on what we find, and we plan for that upfront.

Kitchen and Bath Remodels With Allowances, Not Arguments

On a Highgrove remodel, the single biggest driver of quote movement is what hides behind original framing. Knob-and-tube wiring, cast-iron drains, failing shower pans, undersized beams. We write allowance lines into the contract before demolition, so when a finding appears, it becomes a written change order you approve before we touch it. No shutdown arguments, no buried work.

Additions and ADUs on Graded Pads

Adding square footage on a hillside lot or converting a garage into an ADU means dealing with slope drainage, retaining wall condition, and county permit scrutiny. Home additions in Highgrove run $45,000 – $130,000, and ADU construction runs $90,000 – $220,000. We handle prefab ADUs from Abodu, Dvele, Mighty Buildings, Boxabl, and Plant Prefab, which cuts site time significantly compared to stick-built construction on the same pad.

Hire a General Contractor in Highgrove

When you hire a general contractor in Highgrove, you’re paying for single-contract accountability across every trade and phase. You’re not coordinating a roofer, a window company, a cabinet installer, and a plumber. We manage the roofline to the kitchen counter, including roofing, windows, doors, siding, fencing, hardscaping, and interior remodeling. A paver patio here runs $3,500 – $11,000, and a full roof replacement runs $8,000 – $20,000, with wind uplift detailing specific to this foothills climate.

The Written Change Order Process

Every job in Highgrove gets a written line-item quote before work begins. If we open a wall and find a ruptured cast-iron drain, you get a change order with a specific price, approved in writing before we touch it. The allowance structure means the first surprise doesn’t become a standoff. It becomes a signed piece of paper and a clear path forward.

Permits, Inspections, and the Draw Schedule

We pull permits on every job where the county requires them, and we sequence inspections so no rough-in gets buried before a third-party inspector confirms the work. On pier-and-beam subfloor and slab work, that sequence matters. You get photos, inspection sign-offs, and a draw schedule you can follow from start to finish.

Trusted Brands We Service in Highgrove

We stock parts for the brands most common in Highgrove homes, and we install windows and doors from manufacturers built for inland heat and wind. ECO Window Systems and ES Windows both hold up well to the 95 – 105°F summer highs and Santa Ana gusts that stress cheaper window lines. For glass-heavy remodels and exterior door packages, we also work with CWS and Mr-Glass products, ordered locally so turnaround stays short. When you choose Milpitas Construction, you’re getting premium brands with proper installation, not a big-box grab bag.

Common General Contractor Problems We See in Highgrove Homes

• Undersized framing on hillside pads. Mid-century wood-frame homes on graded lots often carry loads they weren’t designed for. We correct headers, beams, and joist spacing before finish work covers them.
• Failed waterproofing pans in older bathrooms. Stall shower pans from the 1970s and 80s crack, and the first sign is usually a stain on the ceiling below. A tub-to-shower conversion in Highgrove runs $3,500 – $10,000 depending on what the studs reveal.
• Outdated electrical and knob-and-tube wiring. Opening a kitchen wall often exposes wiring that will not pass a 2026 inspection. We price the rewire as part of the initial estimate whenever a crawl or attic inspection shows it’s likely.
• Drainage and retaining wall failure at the uphill edge. Decades-old graded pads shift, and the uphill retaining wall is usually the first structure to show it. We correct drainage before it undermines the foundation or the addition footing.
