ADU Company in Colton, CA

Kitchen remodeling in Colton, CA usually means working inside a 1950s-to-1980s tract home where the original layout, plumbing, and electrical were built for a different era of cooking and entertaining. We handle the full scope of that work, from opening walls in a slab-on-grade house to upgrading 100-amp panels and replacing cast-iron drain lines before new cabinets ever go in. We’re Westminster ADU Builders, and kitchen remodeling here is part of what we think of as the ADU ecosystem: spaces people live in, cook in, and rely on daily, built and finished by one team. Call (833) 620-3521 when you’re ready to talk about the space.

Why Colton Homes Are Different

Colton’s housing stock is predominantly single-story tract homes built between the 1950s and 1980s, and that matters more than most homeowners realize. Many of these houses sit on slab-on-grade foundations, which means moving a sink or adding an island isn’t a simple matter of dropping new plumbing into a crawlspace. The original supply lines are often galvanized steel that has been corroding from the inside for decades, and the drain lines are frequently cast iron with cracks or scale buildup. A kitchen remodel in Colton routinely includes trenching through the slab to relocate or replace those lines, and that’s a cost and schedule factor you won’t see in a newer home or one with a raised foundation.

The second thing that shapes this work is the electrical service. A large share of the original Colton tract homes still run on 100-amp panels, which met code when the house was built but cannot comfortably support a modern kitchen’s induction cooktop, double oven, microwave drawer, and refrigeration, let alone the dedicated circuits code now calls for. Many of our Colton kitchen jobs begin with a panel upgrade to 200 amps, which is also a requirement on most ADU permits in the city. The third factor is heat. Colton sits in the Inland Empire with summers that regularly push past 100°F, so when we design a kitchen that opens to a dining area or a back patio, we’re also thinking about how that space will ventilate and cool through August.

Our Main Colton Services

Homeowners in Colton call us about two projects more than anything else: building an ADU on a lot that wasn’t designed for one, and updating a bathroom to handle either a growing household or a new rental unit. Both come down to the same core challenges. Here’s how each one works in Colton.

ADU Builders in Colton

Colton sits in San Bernardino County, which has become one of the more ADU-friendly jurisdictions in Southern California, with detached units allowed up to 1,200 square feet and impact fees waived for units under 750 square feet. The real constraint in Colton is the lot itself. Many of the older tracts around the 92324 core have only three to four feet between the house and the side property line, so a detached side-yard unit often won’t work, and the project shifts toward a rear-yard build off the alley or a garage conversion. We work through prefab brands like Abodu and Cover plus traditional site-built methods, and we’ll help you sort which path fits your lot before you spend money on plans. ADU Builders in Colton

Bathroom Remodeling in Colton

Bathroom work in Colton’s older homes is rarely cosmetic once you open a wall. Galvanized supply lines, original shower valves, and bathrooms built on a slab all need careful evaluation before tile goes up. For homeowners adding an ADU, the bathroom in that unit becomes a second full scope of work, and for main-home remodels, we often find that the original vent stack and drain configuration need updating to current code. The same heat that drives cooling concerns for kitchens applies to bathrooms too, and proper exhaust fan sizing and venting to the exterior, not into an attic, is part of how we spec every Colton bath job.

Kitchen Remodeling in Colton

Kitchen remodeling in Colton means fixing the way a 1950s-to-1980s tract house cooks, holds people, and moves through the day. The original kitchens in these homes were generally closed off, small, and sized for a family that didn’t own the appliances, cookware, and small electronics most of us have now. The work here tends to involve moving or removing walls, replacing slab-buried plumbing, upgrading electrical from a 100-amp panel to 200 amps, and designing a layout that works with the Inland Empire heat rather than fighting it. We handle everything from the first demolition to the final cabinet hardware, and because we specialize in the full ADU ecosystem, we can also run an ADU’s kitchen as part of the same project without introducing a second contractor. If you’re looking at kitchen work as part of a broader property plan, our Kitchen Remodeling service hub has more detail on scope and approach.

Full Kitchen Renovation

Signs you need it

Your Colton kitchen hasn’t been meaningfully updated since the original build, the cabinet boxes are swelling from decades of heat and moisture cycling, or the layout can’t support two people cooking at once.

What it costs in Colton

A full kitchen renovation in Colton typically runs from $25,000 to $55,000 depending on scope, slab trenching, panel upgrades, and finish level.

How we do it

We gut the space to the studs, correct plumbing and electrical inside the slab and walls, reconfigure the layout if needed, then rebuild with new drywall, flooring, cabinets, counters, appliances, and finishes, all under one contract.

Cabinet Installation and Refacing

Signs you need it

Your cabinet doors are delaminating, hinges sag, drawer slides are failing, or the configuration wastes usable space but the kitchen layout itself works.

What it costs in Colton

Cabinet installation or refacing in Colton typically runs from $7,000 to $18,000 depending on cabinet count, material, and whether you’re refacing existing boxes or replacing everything.

How we do it

We measure every opening, order or build to those dimensions, remove old faces and hardware, and install new doors, drawers, slides, and finishes so the kitchen reads as rebuilt without the cost of moving walls or plumbing.

Countertop and Backsplash Replacement

Signs you need it

Your counters are cracked, stained, burned, or dated, and your backsplash is original 4-inch tile or peeling laminate that’s already failed at the seams.

What it costs in Colton

Countertop and backsplash replacement in Colton typically runs from $5,000 to $12,000 depending on square footage, material, and whether the old counters come out cleanly around existing plumbing.

How we do it

We template the exact footprint after old surfaces are removed, fabricate and install the new counters with sealed seams, then set the backsplash with a waterproof substrate and proper expansion gaps for Colton’s heat swings.

What Kitchen Remodeling Costs in Colton

Item Typical range in Colton
Full kitchen renovation $25,000 – $55,000
Cabinet installation or refacing $7,000 – $18,000
Countertop and backsplash replacement $5,000 – $12,000

Two things push Colton kitchen prices toward the upper end of these ranges: slab trenching for plumbing relocation and panel upgrades from 100-amp to 200-amp service. If you’re in an older 92324 tract home, it’s smart to assume both are possible before the bid comes back. We price those items upfront in a written line-item quote, so the number you sign is the number the job is built against.

How much does a kitchen remodel cost in Colton?

Most full kitchen remodels in Colton land between $25,000 and $55,000, with cabinet-facing work at $7,000 to $18,000 and counters at $5,000 to $12,000. Older slab-on-grade homes with galvanized plumbing or 100-amp panels tend to cost more because of the underground work. Call (833) 620-3521 for an exact quote, the estimate is free.

Will the price change once work starts in Colton?

No, not unless you change the scope. We price Colton jobs with the slab work, panel upgrade, and any hidden plumbing or electrical corrections included upfront. Our quotes are line-item, and we don’t issue change orders for conditions we can see before we start. Call (833) 620-3521 to get a fixed price.

Neighborhoods We Serve in Colton

Our Colton work spans the older tract areas built out from the 1950s through the 1980s, where slab foundations, narrow side yards, and alley access all shape the job. We’re familiar with the permitting flow through San Bernardino County and the way lot geometry changes the build in different parts of the 92324 ZIP.

  • College Park area
  • Meridian district
  • East-side tracts near the railyards
  • Areas off Rancho Avenue
  • North Colton near the 215 corridor

Most Colton estimates can be scheduled within a week, and we build a realistic timeline for slab work, panel upgrades, and inspections before the first day of demolition.

Service Area – Cities Near Colton
