ADU Company in San Bernardino, CA

Kitchen remodeling in San Bernardino usually means working inside a stucco-on-stick house built between the 1950s and 1970s, where original 100-amp electrical panels and slab foundations set the terms for what’s possible. We’re Sentinel ADU Builders, and we’ve served San Bernardino homeowners since 2017 with kitchen remodeling, ADU construction, and bathroom remodeling under one project plan. Call (855) 341-3461 for a free estimate on your San Bernardino kitchen remodel.

Why San Bernardino Homes Are Different

Most San Bernardino homes are post-WWII through 1970s wood-frame construction with stucco exteriors, sitting on larger lots than you’ll find in coastal Southern California cities. The electrical panels in these homes are typically original 100-amp services, which matters the moment you start pulling permits for a kitchen with modern appliance loads. Many homes sit on slab or low pier foundations, so relocating a sink or gas line means cutting concrete, not crawling under a raised floor. The climate adds another layer: hot, dry inland summers with Santa Ana winds mean kitchens need real ventilation design, and intense summer sun pushes cooling loads that a coastal remodel doesn’t face. We plan around all of it.

Our Main San Bernardino Services

San Bernardino homeowners call us most about two projects: building an ADU on a rear-alley lot, and remodeling a bathroom in a house that’s ready for a serious upgrade. Here’s what each involves locally.

ADU Builders in San Bernardino

San Bernardino’s older flatland neighborhoods still have rear service alleys behind the lots, which changes how an ADU should be sited. Instead of tearing up the front yard for a driveway, the smarter play is often routing the ADU’s entrance and parking off the alley, keeping the main house’s frontage intact. We handle the easement and utility checks with the city and Edison before drawings start, then build the unit to San Bernardino’s ADU-friendly rules. ADU Builders in San Bernardino is the full resource on site-built and prefab options here.

Bathroom Remodeling in San Bernardino

Bathrooms in San Bernardino homes from this era often have original cast-iron plumbing, small footprints, and zero exhaust ventilation to code. A real remodel here means assessing slab access for drain moves, upgrading venting for the dry inland air, and choosing finishes that don’t fight the hard water. We do the full scope, from demolition through waterproofing, tile, and fixture install, as one crew under one plan. Bathroom Remodeling in San Bernardino covers the details.

Kitchen Remodeling in San Bernardino

A kitchen remodel in San Bernardino is more than swapping cabinets. You’re working inside a 1950s-to-1970s stucco home with an original 100-amp electrical panel, a slab or low pier foundation, and summers that punish a poorly vented cook space. The job is bringing the electrical, plumbing, and ventilation up to what the house needs, then building a kitchen that works for the way you actually cook. We handle everything from Kitchen Remodeling permits to finish trim as a single point of contact.

Full Kitchen Replacement

Signs you need it

Your cabinet boxes are delaminating, the layout hasn’t changed since the Nixon administration, and the electrical panel can’t support a modern range and refrigerator at the same time.

What it costs in San Bernardino

A full kitchen replacement in San Bernardino typically runs $45,000 to $85,000 depending on cabinet grade, appliance selection, and how much the electrical and plumbing need to move in a slab home.

How we do it

We start with a measured site visit, confirm the panel capacity and slab access, produce a fixed line-item quote, then run the job as one crew from demolition and rough-in through drywall, cabinets, countertops, and finish plumbing.

Kitchen Refresh – Cabinets, Counters, and Finishes

Signs you need it

The layout still works, but the cabinet faces are worn, the laminate counters are chipped, and the whole room reads 1987.

What it costs in San Bernardino

A kitchen refresh in San Bernardino typically lands between $22,000 and $40,000 when you’re refacing or replacing cabinets, installing new countertops, and updating sinks and fixtures without moving walls or utilities.

How we do it

We order new or refaced cabinet fronts, template and install counters, swap plumbing fixtures, and patch and paint all visible surfaces, keeping the kitchen usable for most of the job.

What Kitchen Remodeling Costs in San Bernardino

Item Typical range in San Bernardino
Full kitchen replacement $45,000 – $85,000
Kitchen refresh (cabinets, counters, finishes) $22,000 – $40,000
Countertop replacement only $6,000 – $15,000

Will a San Bernardino kitchen remodel require an electrical panel upgrade?

Often, yes. Most 1950s-to-1970s San Bernardino homes still have 100-amp panels, and adding a modern range, hood, and outlets usually pushes past that. Call (855) 341-3461 and we’ll check yours during the estimate.

How long does a full kitchen remodel take in San Bernardino?

A full replacement typically runs 6 to 10 weeks in San Bernardino, depending on cabinet lead times and whether the slab needs concrete cutting for drain or gas moves. Call (855) 341-3461 for a schedule based on your specific house.

In San Bernardino, two things push pricing higher than a tract-home remodel in a newer development: the age of the electrical panel and the slab foundation. Cutting concrete to move a drain or gas line, plus a panel upgrade from 100 amps to 200, adds real cost. We quote fixed, line-item prices up front so the number you approve is the number you pay.
