Fast, Reliable Home Remodeling Across Ontario
Home remodeling in Ontario, CA typically costs between $9,000 and $130,000 depending on scope, and the single biggest variable in this city is what’s hiding inside the walls of its 1950s and 1960s tract homes. We’re Pinecrest Contractors, and we’ve opened enough Ontario walls to know exactly what that means: cast-iron drain lines, galvanized supply pipes, undersized framing, and sewer laterals that predate current code. If you’re planning a kitchen, bath, addition, or ADU anywhere in Ontario, call (855) 702-1622 and we’ll walk you through what your home likely needs before demolition starts.
Our Home Remodeling team works across Ontario’s 91758, 91761, 91762, and 91764 ZIP codes, and we schedule our Ontario visits around one thing most remodelers never mention: the Inland Empire heat. That’s not a small detail. It changes when concrete gets poured, how stucco cures, and whether a summer remodel stays on schedule.
Why Pinecrest Contractors Is Ontario’s Preferred Home Remodeling Company
Ontario homeowners call us because we show up with a plan, not a sales pitch. Led by Gil Rourke, our crews have worked the full length of Euclid Avenue, through the tract neighborhoods east of it, and into the older pockets around Holt and Mission Boulevards. We know what a 1962 stucco home in 91762 looks like behind the drywall because we’ve seen it dozens of times.
That local knowledge changes how we bid work. When a Ontario homeowner asks us to remodel a kitchen or add a room, we already know the sewer lateral question is coming. We raise it during the walkthrough, not after the change order. Homeowners in central Ontario regularly tell us that detail alone saved them from a surprise five-figure line item. Our work is backed by written line-item quotes, and permits get pulled and inspections passed on every job that requires them.
Styles & brands we work with
Luxury Home Remodeling in Ontario
Luxury Home Remodeling in Ontario means high-end kitchens, spa-level primary baths, and whole-home interior work where material selection matters as much as the construction itself. A Ontario homeowner pursuing this scope is typically working with a $40,000 to $130,000 budget and wants brand-grade cabinetry, stone countertops, and plumbing fixtures built to manufacturer spec, not big-box substitutes. The job often includes moving walls, upgrading electrical service, and replacing the rough-in behind the finishes because the home’s original infrastructure won’t support the new load.
Kitchens and baths with brand-grade materials
We build luxury remodels around Cambria or Silestone counters, Kohler or Moen fixtures, and KraftMaid or Wellborn cabinets, but the real work happens behind the tile. Cast-iron drains and galvanized supply lines in a 1960s Ontario home are typically end-of-life, and we address them before any finish goes in. That’s the difference between a remodel that looks good for a year and one that performs for twenty.
Whole-home interior coordination
For an Ontario homeowner doing a multi-room remodel, one contract covering every trade matters. We sequence plumbing, electrical, framing, tile, and finish work across the whole house so nobody waits on a sub who isn’t ours. Our Home Remodeling in Ontario work often uncovers outdated wiring and failed waterproofing, and homeowners appreciate that we catch it before it becomes a Code violation or a leak.
Full Home Remodel in Ontario
A Full Home Remodel in Ontario typically runs from $45,000 to $130,000 and involves opening most or all of the living space, replacing mechanical systems and rough-in plumbing, and rebuilding interiors to current code. It’s the right scope when a home’s original systems have failed, or when a homeowner wants to rework the floor plan rather than patch it. In Ontario’s postwar tracts, this almost always includes foundation and flatwork repair driven by clay-soil movement that has shifted slabs over decades of dry-wet seasonal cycling.
What a full remodel actually includes
We strip to framing where needed, replace electrical panels and branch circuits, run new pex supply and ABS or cast-iron drains, insulate to current Title 24 energy requirements, and rebuild the living space with new drywall, doors, windows, and millwork. Permits are pulled, and every phase is inspected before it is covered. For a Ontario homeowner, this is the cleanest path to resolving the moisture, wiring, and plumbing issues that older stucco homes accumulate.
One contractor, every system
Because Pinecrest is a full-scope general contractor, a full home remodel in Ontario does not turn into a vendor spreadsheet. Roofing, windows, siding, interior build-out, and hardscape all flow through one team. Gil Rourke coordinates the trades and the materials, and any surprise found behind a wall gets priced in writing before we proceed.
Trusted Brands We Service in Ontario
We install and service material systems from the brands Ontario homeowners actually ask about, including CertainTeed service in Ontario. For hardscape tied to a remodel, that includes Belgard and Cambridge Pavers for paver patios and driveways, and Quikrete products when a concrete pour, repair, or foundation patch is part of the scope. We also stock common repair and rough-in components locally for Ontario jobs, which shortens the wait when a shower valve or drain line fails mid-project. If a homeowner wants Unilock instead of Cambridge, we’ll show both options and build to the manufacturer’s spec either way.

AfterCommon Home Remodeling Problems We See in Ontario Homes
- Original sewer laterals that fail inspection. In central Ontario (91761 and 91762), any room addition or ADU almost always hits an original sewer lateral that must be replaced before the city signs off. We treat lateral replacement as a near-standard line item in the scope, not a surprise.
- Cast-iron drains and galvanized supply lines behind stucco. Homes built between 1950 and 1975 often have plumbing that has been quietly corroding for decades. A cosmetic remodel turns into a full rough-in replacement the moment the wall is opened, and we plan for that before demo starts.
- Clay-soil foundation movement cracking slabs and tile. Ontario’s clay-heavy soil expands with winter moisture and contracts in the summer heat. That movement cracks slab foundations, makes floors uneven, and causes tile failures a simple overlay cannot fix.
- Summer heat wrecking concrete finishes. From June through September, Ontario routinely hits 100°F before noon. Concrete poured after 10 a.m. sets too fast to finish properly, producing shrinkage cracks. We schedule pours at dawn in summer, and that detail matters for any addition, ADU, or patio slab.

FAQs About Home Remodeling in Ontario
Because Ontario’s building department inspects all new plumbing work against current code, and the city’s original laterals from the 1950s and 1960s are typically cracked, sagging, or root-intruded. Once you add square footage or an ADU, the lateral has to be camera-scoped, and a failed scope means replacement before final sign-off. In central Ontario (91761/91762), we treat lateral replacement as a standard line item, not a surprise. Call (855) 702-1622 if you want us to scope your lateral before you start budgeting.
We write allowances into every Ontario contract before demo begins, based on what we find during the pre-demo inspection. If we open a wall and find cloth-wrapped wire, a spliced circuit, or undersized framing, we photograph it, document it, and issue a written change order with the exact added cost before any repair work starts. We never close a wall over work that will fail an inspection. Call (855) 702-1622 and we’ll explain the allowance structure before you sign anything.
An inspector checks structural framing, electrical rough-in, plumbing rough-in, insulation, and final installed fixtures against current code, not the code from when your home was built. That gap is exactly why a 1960s Ontario remodel often triggers upgrades to the panel, the grounding system, the drain lines, and the sewer lateral. We schedule inspections in sequence and walk the job with the inspector, which keeps a Ontario remodel from stalling on a correction notice.
Because Ontario’s summer heat routinely passes 100°F by late morning, and concrete that sets too fast shrinks and cracks. Pouring at dawn lets the mix cure evenly, and we adjust the mix design with retarders when an afternoon pour is unavoidable. It’s one of those local details that only matters in the Inland Empire, and it’s why our Ontario flatwork and foundation patches hold up.
We start with a foundation and slab assessment, especially for homes east of Euclid Avenue where clay-heavy soil movement is common across Ontario’s tract housing stock. If there’s movement, we address it at the structural level rather than covering it with tile or flooring. For a room addition or ADU, we may recommend a deeper footing or soil treatment, and that gets priced into the base bid, not added later. Call (855) 702-1622 for a free estimate that accounts for Ontario’s soil reality.
