Fast, Reliable Home Renovation Across Ontario
Home renovation in Ontario, CA means dealing with a specific kind of housing stock: mid-century tract homes built fast, remodeled informally, and now hitting the age where galvanized pipes fail and load-bearing walls hide behind fresh drywall. We know these houses because we work on them every week. Sawyer Remodeling gives you a written price before any work starts, sends background-checked uniformed technicians, and runs every project under The Relay Visibility Guarantee: live arrival time, photo updates before and after, and a digital invoice you pay from a link. If you’re planning a kitchen, bathroom, addition, or garage conversion in Ontario, call (254) 272-5876 for a free estimate and a straight answer on what the job will actually cost.
Why Sawyer Remodeling Is Ontario’s Preferred Home Renovation Company

Ontario homeowners keep our schedule full because we do what we say we’ll do. No ghosting between the quote and the finish. The 365-Day Done Right Promise means if something isn’t done right, we make it right, in writing, on every project. That matters when you’re spending $14,000 on a kitchen or $90,000 on an ADU.
Our crews serve Ontario locally from the brand’s Inland Empire (Riverside-San Bernardino) office, so we’re not a distant corporate outfit pretending to know your neighborhood. We know that a home near the 60 Freeway corridor often has different structural issues than one in newer subdivisions east of Vineyard Avenue. That local knowledge changes how we scope the work and what we warn you about before you sign.
Luca Romano, who leads our team, insists on one rule above all: the number on the invoice is the number you approved. Every project gets a written price before a single tool is picked up. That’s not a perk. It’s how we operate.

Home Renovation Contractors in Ontario
Home Renovation Contractors in Ontario handle the full scope of a remodel: structural changes, plumbing, electrical, finishes, and permits. A homeowner in Ontario needs a contractor when the project touches anything beyond paint and fixtures. Expect a kitchen remodel in Ontario to run $14,000 – $45,000, a bathroom remodel $9,000 – $28,000, and a home addition $45,000 – $130,000. The city’s Community Development Department requires permits for interior remodels that alter structural, electrical, plumbing, or mechanical systems, so a real contractor pulls those before demolition starts.
Permit-Pulled Structural Work
Load-bearing walls in 1950s and 1960s Ontario homes often have undersized framing or hidden prior modifications. We pull permits, bring in engineered plans when required, and reframe with properly sized headers. This is the work that separates a licensed contractor from a handyman who will open your wall and walk away when it gets complicated.
Full-Scope Remodeling
When a kitchen, bathroom, or addition needs to happen all at once, our Home Renovation team coordinates plumbing, electrical, drywall, tile, cabinets, and countertops under one written price. You’re not juggling five subcontractors. You get one schedule, one invoice, one person to call.
Home Renovators in Ontario

Home Renovators in Ontario focus on transforming existing space: kitchens, bathrooms, garage conversions, and finish work. The typical trigger is a homeowner who loves their Ontario neighborhood but needs the house to work differently. A small kitchen remodel in Ontario starts around $9,000 and a full kitchen can hit $45,000. Garage conversions run $30,000 – $80,000 depending on whether the slab, electrical, and insulation need upgrades to meet the city’s current code for living space.
Mid-Century Home Upgrades
Ontario’s post-WWII tract homes near Euclid Avenue and Holt Boulevard often have original galvanized plumbing and 2×4 ceiling joists. A renovator who knows these houses checks for both before quoting. We do. It changes the price and the schedule, and it keeps your inspection from failing on rough-in day.
Garage and ADU Conversions
Converting an attached garage into a bedroom, office, or rental ADU is common in Ontario, but many existing garages were never permitted as living space. We verify prior permits, bring the slab, electrical, and insulation up to code, and pull the required approvals. It’s slower than slapping down carpet and calling it a day, but it passes inspection and adds real value.
Trusted Brands We Service in Ontario
We stock and install name-brand materials for Ontario customers, so you’re not waiting on mystery-supplier parts from out of state. Our remodels use cabinets from KraftMaid, countertops from Cambria, fixtures from Kohler, and exterior products from GAF and James Hardie. For homeowners interested in factory-built options, we also work with brands like Abodu and Cover on prefab ADU projects. Manufacturer-backed products mean if a material fails, you’re not fighting a store-brand warranty. You’re covered by the people who made it. That matters when you’re spending five figures on a kitchen or a roof.

AfterCommon Home Renovation Problems We See in Ontario Homes
- Unpermitted prior work. Ontario’s older housing stock near the 60 Freeway corridor has plenty of patio enclosures and garage conversions done without permits. When we open a wall for a remodel, we often find electrical or plumbing that won’t pass current inspection, and it has to be corrected before we can close the wall back up.
- Load-bearing walls with undersized framing. Mid-century tract homes were built fast with 2×4 ceiling joists. Remove the wrong wall and you’ve got sagging drywall and a structural problem. We identify load-bearing walls before demolition, not after.
- Original galvanized plumbing. Homes built in the 1950s and 1960s throughout Ontario still have galvanized supply lines that corrode from the inside. A remodel is the right time to replace them, because opening walls twice is a waste of your money.
- Material lead-time surprises. Cabinet and countertop lead times from Inland Empire suppliers can swing 4 – 6 weeks depending on the season and brand. We factor that into the schedule up front so you’re not living without a kitchen for an extra month.
Pricing for Home Renovation in Ontario, CA
Here’s what Ontario homeowners should expect to pay for common projects. These are real ranges based on the city’s housing stock and current material costs, not vague ballparks.
| Project | Typical Price Range in Ontario |
|---|---|
| Kitchen Remodel | $14,000 – $45,000 |
| Bathroom Remodel | $9,000 – $28,000 |
| Home Addition | $45,000 – $130,000 |
| Garage Conversion | $30,000 – $80,000 |
| Countertop Installation | $2,000 – $6,500 |
What moves the number within those ranges: the age of your home’s plumbing and electrical, whether prior work was permitted, the cabinet and countertop brands you choose, and whether the city requires engineered plans for your structural changes. The written price we give you before work starts includes all of that. If something changes mid-project, you approve the change order before we spend a dollar. That’s the whole point.

FAQs About Home Renovation in Ontario
Yes, if the wall is load-bearing or if removing it alters structural, electrical, plumbing, or mechanical systems, the City of Ontario’s Community Development Department requires a permit. In practice, many walls in Ontario’s mid-century homes turn out to be load-bearing even when they don’t look like it. We check the structure and pull the permit before any demolition starts. Call (254) 272-5876 for a free estimate and we’ll tell you what your specific wall requires.
A kitchen remodel in Ontario typically runs 6 – 10 weeks from demo to final inspection. A bathroom remodel is usually 3 – 5 weeks. A home addition or garage conversion can run 3 – 6 months depending on permit review time and structural work. The biggest schedule risk in Ontario is discovering unpermitted prior work or undersized framing once the walls are open, so we scope that upfront whenever possible. Call (254) 272-5876 to get a timeline for your specific project, free.
A kitchen remodel in Ontario runs $14,000 – $45,000 depending on the size of the kitchen, the cabinet and countertop brands you select, and whether we’re moving plumbing or electrical. A smaller kitchen with stock cabinets and a basic countertop falls on the lower end. A full gut with KraftMaid cabinets, a Cambria countertop, and layout changes lands higher. The written price you approve before work starts is the price you pay. Call (254) 272-5876 for an exact quote.
A change order is a written addendum to your contract that lists the new work, the new price, and the new timeline. At Sawyer Remodeling, nothing gets added without your written approval first. The most common change order trigger in Ontario is discovering unpermitted prior work or corroded plumbing behind finished walls once demolition starts. We show you photos, explain what’s needed, and give you the number before we proceed. Call (254) 272-5876 to talk through your project and how we handle surprises.
