ADU Company in Fontana, CA
Kitchen remodeling in Fontana usually runs $22,000 to $55,000 for a full gut-and-replace, while smaller refreshes land between $12,000 and $22,000, but the real variable here is what’s behind the walls of a 1960s stucco tract home. Fontana’s housing stock is dominated by 1950s-to-1980s single-story slab-on-grade construction, which means old 100-amp electrical panels, shallow plumbing runs, and layouts that were never designed for modern appliance loads or open-concept flow. Orange ADU Builders has served Fontana since 2013, and we’ve learned that the best remodels here are planned around the house you actually have, not the one in a catalog photo. Call us at (877) 265-5812 and we’ll walk your kitchen before we quote it.
Why Fontana Homes Are Different
Fontana sits at the foot of the Cajon Pass, and the same geography that made it a railroad town shapes how homes here behave. Santa Ana winds funnel down through the pass and hammer rooftops, fences, and any exterior wall facing north or east. For kitchens, that shows up as rattling vent hoods, dust intrusion around poorly sealed windows, and backdrafting issues on windy afternoons. We account for wind-rated flashing and tight gaskets on every exterior penetration, because a kitchen that fights Fontana’s gusts is a kitchen that wears out fast.
The dominant housing stock south of the 210, in ZIPs 92335 and 92337, runs to compact single-story layouts on slab foundations. That means moving a sink or adding a gas line is not a matter of dropping into a crawlspace; it often means cutting concrete, trenching, and coordinating with code officials on slab penetrations. Summer heat is the other constant. July and August routinely push past 100 degrees, so exhausted kitchen air, efficient mini-split cooling, and glazing choices on south-facing windows directly affect how usable the room is from June through September. Fontana remodels are less about fashion and more about making an older home function like a newer one without pretending it has a different skeleton.
Our Main Fontana Services
Most Fontana homeowners call us about one of two things: adding a detached unit to their deep backyard lot, or fixing a dated bathroom in a house that’s otherwise holding up fine. Both jobs share the same Fontana realities of slab foundations, older electrical services, and wind exposure.
ADU Builders in Fontana
Fontana’s post-WWII and 1960s-era lots south of the 210 are wider and deeper than most Inland Empire parcels, so a detached ADU here often reads as a true second house rather than a converted garage. That’s a real opportunity for rental income or multigenerational housing, but it collides with San Bernardino County setback math, lot-coverage caps, and Fontana’s own parking and utility-connection rules. We’ve worked detached units into alleys, side yards, and behind existing garages across 92335 and 92337, and we know which lot shapes actually work. See how we approach the whole process on our ADU Builders in Fontana page.
Bathroom Remodeling in Fontana
Most Fontana bathrooms from the 1960s and 1970s have the same signature: a cramped tub-shower combo, a single-gang electrical box, and tile laid over drywall that’s been absorbing shower steam for forty years. When we open these up, we routinely find moisture damage and ventilation that never met code in the first place. Our Fontana bathroom work includes full gut replacements, walk-in shower conversions, and aging-in-place layouts for families planning to stay in the home.

Kitchen Remodeling in Fontana
A Fontana kitchen remodel is a different animal from a coastal Orange County refresh. Homes here were built when one 20-amp circuit ran the whole room, when ranges were gas or electric but never induction, and when nobody had a double-door refrigerator. So the typical Fontana project is not just new cabinets and counters: it’s a panel upgrade to 200 amps, dedicated appliance circuits, slab cutting for a relocated sink or island plumbing, and rethinking a galley layout that closes the cook off from the rest of the house. The heat matters too. A poorly ventilated kitchen in a Fontana summer hits 90 degrees before the oven finishes preheating, so we spec real CFM on exhaust hoods and treat cooling as part of the design, not an afterthought. If you’re weighing a full kitchen remodel against refreshing what’s there, our Kitchen Remodeling overview explains the scope of work we take on.
Full Gut Kitchen Replacement
Signs you need it
Your cabinets are particleboard and delaminating, the layout traps two people behind a peninsula, and the electrical panel can’t support a modern appliance load.
What it costs in Fontana
A full gut-and-replace kitchen in Fontana typically lands between $22,000 and $55,000 depending on cabinet grade, appliance package, and how much slab cutting the new layout requires.
How we do it
We demo to studs, run new electrical and plumbing, patch the slab, hang and finish drywall, then install cabinets, counters, appliances, and flooring with licensed trades at every step.
Cabinet Refacing and Countertop Replacement
Signs you need it
The cabinet boxes are still square and solid, but the doors are scratched, the hinges sag, and the laminate counters are burned or peeling at the seams.
What it costs in Fontana
Refacing plus a mid-grade countertop replacement in Fontana runs $8,000 to $15,000, with the final figure driven mostly by surface material and linear feet of cabinet face.
How we do it
We build new door and drawer fronts to fit the existing boxes, replace hinges and slides, then template and install the new counter surface over one to two weeks depending on material lead times.
What Kitchen Remodeling Costs in Fontana
| Item | Typical range in Fontana |
|---|---|
| Full gut kitchen replacement | $22,000 – $55,000 |
| Cabinet refacing + countertops | $8,000 – $15,000 |
| Panel upgrade to 200 amps (kitchen scope) | $1,500 – $3,500 |
How long does a full kitchen remodel take in Fontana?
A full gut kitchen in Fontana takes four to eight weeks from demo to final walkthrough. Lead times on custom cabinets and slab quartz are the biggest variable, so we lock material selections in writing before we open a single wall.
Will the price change once the walls are open?
Not without your approval. We quote on what we can see and flag the known unknowns like slab plumbing depth and old wiring in the estimate itself. If demo uncovers something structural, we stop, show you photos, and get sign-off before any change order is written.

We quote the job as a fixed, line-item estimate before we start, and we don’t write change orders without your written sign-off.
