Why Hampton Contractors Is Ontario’s Preferred Home Remodeling Company
Ontario homeowners keep calling us back because we do not flinch at what these houses hide. The 1950s – 1970s stucco tract homes that fill the core neighborhoods around Euclid Avenue and Holt Boulevard were built on slab foundations over shrink-swell clay. That means when we open a kitchen wall for a load-bearing beam, we expect to find hairline slab cracks, original two-wire cloth wiring, and framing that has shifted over sixty years of hot summers and Santa Ana wind cycles. We build that expectation into the quote from day one, not after demolition starts.
Brent Calloway leads our Ontario projects personally, and his approach is simple: inspect first, write allowances into the contract, and price every surprise as a written change order before we touch it. That is why homeowners in 91761, 91762, and 91764 trust us over contractors who write a low number and then hand over a stack of unapproved overruns once the walls are open. We are Home Remodeling specialists who carry 50-plus nationally recognized product brands, so you get KraftMaid cabinets, Cambria quartz counters, Kohler fixtures, and GAF-certified roofing without stitching together four different subcontractors.
Our response time to Ontario is measured in days, not weeks. We keep crews and material orders moving across the Inland Valley, and because we handle roofing, siding, windows, interiors, and hardscaping under one contract, you are not waiting on a chain of handoffs. When a Ontario homeowner calls us about a kitchen remodel, they get a straight answer: this is what it costs, this is what we will find, and this is how we will handle it.
Styles & brands we work with
Home Remodeling Companies in Ontario
Home Remodeling Companies in Ontario split into two groups: the industrial and warehouse builders working the I-10 and 60 corridors, and the residential remodelers handling the older infill housing stock in the core neighborhoods. Hampton Contractors is firmly in the second group, and we have spent years learning what the 1950s – 1970s slab-on-grade homes in 91761, 91762, and 91764 reveal when you start pulling permits and opening walls. The honest truth is that most Ontario remodel quotes are written without allowances for the rewire, framing repair, and code upgrades that a permit nearly always triggers. That is not how we quote.
Permit-Triggered Upgrades
When you pull a permit on an older Ontario home, the city will require bringing opened areas up to current code. That usually means replacing original two-wire cloth wiring with grounded circuits, adding GFCI protection in kitchens and baths, and sometimes upgrading the panel. A quote that does not include an electrical allowance is a quote that will blow up in week two.
Slab and Stucco Reality
Decades of slab-on-grade construction over hot-and-dry shrink-swell clay means foundation cracks and stucco hairline fractures are routine in Ontario’s older core. We inspect for these before we bid, and we write the repair work into the contract as a line item, not a possibility.
Whole House Remodel in Ontario
A Whole House Remodel in Ontario is not the same job as a whole house remodel in a 1990s subdivision. Here, we are typically working on a single-story stucco tract home built between 1955 and 1975, with original framing, two-wire electrical, cast-iron drain lines, and a slab that has been moving for sixty years. The scope usually includes opening load-bearing walls, updating every mechanical system, replacing windows and exterior seals, and reworking the floor plan to fit how families actually live now. Budgets in Ontario for this scope generally start around $45,000 and run up to $130,000 for a full gut and reconfiguration.
What We Open Up
On a 1962 slab-on-grade tract home off Euclid Avenue in 91762, our crew opened a galley kitchen wall for a load-bearing beam and found the original two-wire cloth wiring plus framing that had cracked along a shrink-swell clay seam. We stopped, brought the structural engineer and city inspector in for a rough-in review, priced the rewire and framing repair as a written change order, and only then set the KraftMaid cabinets and Cambria counters. That is our process on every whole-house job in Ontario.
Interior to Exterior Under One Contract
Because a whole house remodel usually means touching the exterior too, we run roofing, siding, windows, and doors on the same schedule as the interior work. James Hardie siding, PGT windows, and GAF-certified roofing go on while the inside is down to studs, so you are not dragging the job out across six different trade contractors.
Trusted Brands We Service in Ontario
Ontario homeowners deserve materials they can walk into a showroom and recognize, and we carry exactly that. We stock and install KraftMaid and Wellborn cabinetry, Cambria and Silestone quartz countertops, Kohler and Moen plumbing fixtures, GAF and CertainTeed roofing, James Hardie siding, and Belgard pavers for exterior and hardscaping work. For Ontario’s older-core homes, we keep local parts and material availability in mind, because a 1960s tract home needs different flashing details, sealants, and window retrofits than a 2005 stucco build. When we quote a remodel in 91764, we are quoting the materials that actually fit the house, not the ones sitting on a warehouse shelf in another county.

AfterCommon Home Remodeling Problems We See in Ontario Homes
- Original two-wire cloth wiring. Nearly every 1950s – 1970s Ontario tract home we open still has ungrounded cloth-insulated wiring that must come out when walls are open. We budget for a full or partial rewire and panel upgrade in every whole-house quote.
- Slab cracks from shrink-swell clay. The hot-and-dry clay under Ontario’s older core ZIPs expands and contracts through every summer heat cycle, leaving hairline to moderate slab cracks that telegraph into interior framing and stucco.
- Failed shower pan waterproofing. In older Ontario bathrooms, original shower pans were often built with tile set directly over mortar and no modern membrane. We find these failures only after demo, which is why we always include a waterproofing line item.
- Santa Ana wind damage to exterior seals. Wind-driven dust and debris stress flashing, caulking, and roof deck seals across Ontario’s wind corridor. Exterior work scheduled without checking the wind advisory calendar cures too fast and cracks before the punch list.

FAQs About Home Remodeling in Ontario
Because most quotes for Ontario’s 1950s – 1970s slab-on-grade tract homes are written without allowances for the rewire, framing repair, and permit-triggered code upgrades that almost always show up once walls are open. We write those allowances into the contract up front, and any additional surprise is priced as a written change order before we proceed. Call (833) 467-4075 to get a quote that reflects what your Ontario home will actually need.
If you are opening walls, moving plumbing, running new electrical, or changing load-bearing structure in Ontario, you need permits, and skipping them puts you, your home, and any future buyer at risk. We pull all required permits and coordinate inspections, and we build the permit-triggered code upgrades into the quote from the start. Call (833) 467-4075 if you want a permit-ready estimate for your project.
We inspect for slab and stucco cracks before we bid, and we price the structural repair as a line item in the contract. The shrink-swell clay under Ontario’s core ZIPs moves every summer, so we specify repair methods that hold up to that movement rather than just masking the cracks. Call (833) 467-4075 for a free estimate that includes a straight assessment of your slab condition.
A kitchen remodel in Ontario runs $14,000 to $45,000, with the spread driven by cabinet grade, countertop material, whether you are moving walls or plumbing, and how much electrical and structural work the permit triggers. We quote kitchens with brand-name materials like KraftMaid cabinets and Cambria quartz counters so you know exactly what you are paying for. Call (833) 467-4075 for a free line-item quote.
Yes, and we schedule exterior work like stucco, roofing, and exterior sealing around the Santa Ana wind advisories that hit Ontario’s wind corridor. Exterior patches and coatings that cure too fast in hot, windy conditions crack before the job is done, so we adjust our schedule and materials accordingly. Call (833) 467-4075 to talk about timing your remodel around Ontario’s wind season.
