Why Bradford Remodeling Is Ontario’s Preferred General Contractor Company
Homeowners in Ontario call us because we run a disciplined job site. Curtis Lane, who leads our Ontario crews, grew up on the trade’s paperwork side: change orders, inspection sign-offs, and written scopes. That means the crew that shows up at your door on Holt Boulevard already knows what’s behind your walls and what San Bernardino County will ask for at inspection.
Our Ontario customers tell us the same thing: the crew showed up when they said they would, the price did not move, and the site was clean at the end of every day. We do not lean on charm. We lean on documentation. The Garrison Standard requires a written price before any work starts, a signed scope, and a 365-Day Done Right Promise on every completed project. If our work fails within that year, we return and correct it at no charge. That is the whole point.
Response time to Ontario is straightforward: when you call, a live person answers. No callback queue. We schedule the initial walkthrough around your availability, typically within a few business days. Our office coordinates from the Inland Empire, so a two-day notice is standard for us in Ontario.
Styles & brands we work with
Hire a General Contractor in Ontario
Hire a General Contractor in Ontario when the project touches more than one trade. Moving a wall, adding a bathroom, or replacing a roof means plumbing, framing, electrical, and inspections that have to happen in a specific order. We handle that sequence so you do not have to. A kitchen remodel in Ontario runs $14,000 – $45,000 depending on cabinet grade, layout changes, and the condition of the existing plumbing and electrical. A bathroom remodel typically lands between $9,000 and $28,000.
Scope and Permit Management
Before we quote, we look at what is behind the finishes. In Ontario, that often means galvanized steel supply lines and old wiring in homes built during the 1950s and 1960s. We identify these early so the written price reflects reality. We also pull the required San Bernardino County permits and walk the project through every inspection.
Lead-Safe Work on Pre-1978 Homes
Ontario has a large stock of homes built between 1945 and 1970. If yours falls before 1978, any wall, ceiling, or window work that disturbs painted surfaces requires lead-safe practices. We test for lead before demolition and, when needed, bring in a certified lead-safe crew. Skipping this step can trigger a stop-work order and a CDPH fine. We do not skip it.
General Contractor Services in Ontario
General Contractor Services in Ontario cover the full sequence from initial scope to final inspection sign-off. Our core work here includes kitchen remodeling, bathroom remodeling, whole-home updates, room additions, and roof replacement. A roof replacement in Ontario runs $8,000 – $20,000 depending on square footage and material. A home addition starts around $45,000 and can reach $130,000 for larger builds.
Kitchen and Bath Remodeling
We install KraftMaid and Wellborn cabinetry, Cambria and Caesarstone countertops, and Kohler and Moen fixtures. Cabinet installation in Ontario runs $4,000 – $13,000, and countertops land between $2,000 and $6,500. These are documented brands with manufacturer specs, so you know exactly what you are paying for.
Whole-Home and Structural Work
Whole-home remodels and additions require a tighter sequence. We coordinate structural framing, rough-in inspections, insulation, drywall, and finish trades. On projects that involve exterior work, we specify GAF for roofing and James Hardie for siding and trim. Every change in scope gets a written change order before the work happens, so the final invoice never surprises you.

Trusted Brands We Service in Ontario

You get a written material list before we order, so there’s no guessing on brand or grade.

AfterCommon General Contractor Problems We See in Ontario Homes
- Demolition without lead testing. Starting wall or ceiling work on a pre-1978 Ontario home without testing for lead triggers stop-work orders and potential CDPH fines. We test on every pre-1978 job before the first hammer swings.
- Flat quotes that miss galvanized plumbing. Many Ontario homes from the 1950s and 1960s still have galvanized steel supply lines and failing shutoff valves. A flat quote without inspecting these turns into a change order after the wall is open. Our written price accounts for what we actually see.
- Missed San Bernardino County permits. Moving a wall or replacing a roof without the required county permit forces a tear-out of finished work later. We pull permits before work starts and schedule inspections as part of the job calendar.
- Old aluminum wiring behind walls. Homes built in Ontario’s post-war boom often have aluminum branch circuits. We check for this during the walkthrough and include any rewiring in the initial scope instead of springing it on you mid-project.

FAQs About General Contractor in Ontario
Yes. Any kitchen remodel in Ontario that moves plumbing, electrical, or walls requires a San Bernardino County permit. We pull the permit, schedule the rough-in and final inspections, and hand you the signed inspection card at close. Skipping the permit means the work is not legal and will cause problems when you sell. Call (903) 568-7222 for an exact scope review, free.
The honest answer: only the things you choose to add, or conditions we could not see before opening a wall. In Ontario, that often means galvanized plumbing, aluminum wiring, or lead paint discovered in pre-1978 homes. We document these in writing and get your sign-off on a change order before proceeding. The base price does not move on its own. Our written estimate includes a detailed scope so there are no surprises at the door. Call (903) 568-7222 to get your written price.
A standard bathroom remodel in Ontario takes 3 to 6 weeks from demo to final inspection, depending on scope, material lead times, and San Bernardino County inspection scheduling. A tub-to-shower conversion runs $3,500 – $10,000 and lands on the shorter end. A full gut with layout changes takes longer. We give you a written calendar with milestone dates before we start. Call (903) 568-7222 to schedule a walkthrough.
Because San Bernardino County and CDPH require lead-safe work practices on any renovation that disturbs painted surfaces in pre-1978 homes. Ontario has a large post-war housing stock, so this applies to a lot of our jobs. We test for lead, document the results, and bring in a certified lead-safe crew when required. Working without that certification risks fines and a stop-work order. Call (903) 568-7222 and we will check your home during the estimate.
Three things: a line-item price, a written scope of work, and a signed guarantee. Bradford Remodeling gives you all three under The Garrison Standard before any tool comes out. The 365-Day Done Right Promise covers every completed project for a full year; if our work fails, we return and fix it at no charge. No verbal reassurances. No handshake pricing. Call (903) 568-7222 to get yours in writing.
If you are planning a remodel in Ontario and want a crew that shows up, puts the price in writing, and stands behind the work for a year, call (903) 568-7222. We will walk the site, give you a straight number, and tell you exactly what the job requires. Estimates are free.
