Construction in Ontario, CA
Kitchen remodeling in Ontario typically runs $14,000 to $45,000 for a full project, with pricing shaped by the city’s split housing stock: 1950s-1970s ranch homes in the north needing full system upgrades, and new Ontario Ranch builds in the south where homeowners want builder-grade finishes replaced within a few years of moving in. The inland heat and Santa Ana winds also push material choices toward harder-wearing cabinets, countertops, and hardware. Call (470) 298-9650 for a written line-item quote before any work begins.
Why Ontario Homes Are Different
Ontario sits at the convergence of two of Southern California’s largest concurrent construction booms. To the south, the Ontario Ranch master-planned community is one of the biggest active residential developments in the Inland Empire, with tens of thousands of planned units. To the north and center, established 1950s-1970s ranch and post-war tract neighborhoods hold homes with original electrical panels, galvanized plumbing, and single-pane windows that run up against current California building codes on any remodel. Add the dual-market pressure: contractors working Ontario must be equally competent in high-volume tract home subdivision work and the explosive industrial/warehouse corridor around Ontario International Airport, driven by e-commerce logistics. That dual demand pulls skilled labor in two directions at once, which is why written scopes and disciplined scheduling matter more here than in neighboring cities.
The climate does real work against a home. Ontario’s position inland and near the Cajon Pass funnel means it regularly absorbs intense Santa Ana wind events that exceed coastal and valley-floor cities. Summer temperatures routinely surpass 105°F with very low humidity and high UV exposure, accelerating degradation of exterior finishes, caulking, and roofing materials faster than on the coast. And the expansive clay and adobe soils across southern Ontario, especially moving toward the Chino border, require post-tensioned engineered slabs as standard practice. Contractors accustomed to coastal LA conditions get caught underestimating foundation specs and soil prep costs when bidding new construction here.
Our Main Ontario Services
Two services Ontario homeowners call about most are fence installation and driveway and pavers work, both driven by the city’s mix of older lots and new Ontario Ranch builds. Here is how each job works in this city.
Fence Installation in Ontario
Fence work in Ontario spans two extremes: replacing weathered cedar and chain-link on 1950s and 60s lots in the north, and installing brand-new perimeter fencing on raw Ontario Ranch lots where HOA design standards often dictate material, height, and color. Santa Ana winds mean posts need deeper embedment and heavier concrete collars than a coastal fence job would require. Fence Installation in Ontario covers the full scope, local pricing, and what the city permits require.

Driveway & Pavers in Ontario
Driveway and paver work in Ontario has to account for expansive clay soil. A poorly prepped base will crack within a couple of seasons as the soil swells and shrinks through wet winters and 105°F summers. Pavers generally handle that movement better than poured concrete, but only if the base is compacted to spec. Driveway & Pavers in Ontario covers paver versus concrete pricing, soil prep, and what a written quote should include.

AfterKitchen Remodeling in Ontario


A full kitchen remodel in Ontario runs $14,000 to $45,000 depending on size, layout changes, and material grade. Homes in north Ontario built from the 1950s through 1970s often need the wiring and plumbing brought to current code before cabinet and countertop work can proceed, which adds cost that newer Ontario Ranch homes do not carry. The dry inland heat also means solid wood doors and UV-stable finishes hold up measurably better than veneers and soft paints in this climate. Our Kitchen Remodeling work starts with a written price and scope, so the number you see is the number you pay unless a change order is signed.
Full Kitchen Remodeling
Signs you need it
You are working around a layout that no longer functions, cabinets are delaminating from decades of hot dry air, or appliance replacement keeps revealing wiring and plumbing that is out of code.
What it costs in Ontario
Full kitchen remodeling in Ontario typically runs $14,000 to $45,000, with the spread driven by square footage, whether walls move, and the grade of cabinets and countertops.
How we do it
We measure and document the existing conditions, write a flat-price scope with named materials, pull the Ontario permits, then demo, rough in electrical and plumbing to current code, and finish with cabinets, counters, tile, and trim.
Cabinets & Countertops
Signs you need it
Doors are delaminating, drawer slides are failing, or countertop seams have opened from repeated heat and low-humidity shrinkage.
What it costs in Ontario
Cabinet installation runs $4,000 to $13,000 and countertop installation runs $2,000 to $6,500 in Ontario, with brands like KraftMaid and Cambria priced honestly in the written quote.
How we do it
We measure to the half-inch, order cabinets and counters from named brands, then install with shims and scribes that do not rely on caulk to hide gaps.
Backsplash, Tile & Flooring
Signs you need it
Tile is cracked, grout is staining past the point of cleaning, or the floor runs out of level more than a quarter inch across the room.
What it costs in Ontario
Backsplash installation in Ontario runs $800 to $2,500, and flooring work is priced per square foot after we measure the substrate condition.
How we do it
We check the wall plane and floor deflection first, install a membrane where moisture or movement is a concern, then set tile with a level ledger and clean grout lines.

Will the price change once kitchen work starts?
No, not without a signed change order. Under Clause 1 of The Haven Standard, the written price is delivered before any work starts, and no change proceeds until you sign off on the adjustment. Call (470) 298-9650 for a written quote.
Bathroom Remodeling in Ontario


Bathroom remodeling in Ontario runs $9,000 to $28,000 for a full project, with the older north-end homes frequently needing rotted subfloor and exhausted cast-iron drain lines addressed before new tile and fixtures go in. Hot, low-humidity summers also make proper bathroom exhaust ventilation a code issue worth designing for, not an afterthought. Our Bathroom Remodeling quotes name every fixture and finish before the crew arrives, so the written price is the number you plan around.
Full Bathroom Remodeling
Signs you need it
The shower pan leaks, the vanity has swollen from years of low-humidity and water exposure, or the floor deflects underfoot.
What it costs in Ontario
A full bathroom remodel in Ontario runs $9,000 to $28,000, with scope changes driven by the condition of the subfloor, drain lines, and existing waterproofing.
How we do it
We pull the permit, remove finishes to expose framing and plumbing, replace what is compromised, install a full waterproofing membrane behind the tile, and set fixtures from named brands like Kohler.
Walk-In Showers & Shower Remodeling
Signs you need it
Grout is failing, the pan leaks, or the shower has no ventilation and the enclosure is developing mold in the Ontario heat.
What it costs in Ontario
Walk-in shower installation runs $4,500 to $12,000 and shower replacement runs $3,000 to $8,500 in Ontario, depending on glass type and plumbing moves.

What Bathroom Remodeling Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Full Bathroom Remodel | $9,000 - $28,000 |
| Small Bathroom Remodel | $5,000 - $12,000 |

Do you pull the permits for bathroom work in Ontario?
Yes. We pull all required Ontario permits for bathroom remodels that involve plumbing or electrical changes, and the permit record is part of the documentation you receive. Call (470) 298-9650 to discuss your project.
Roofing in Ontario


Roof replacement in Ontario runs $8,000 to $20,000 for a typical asphalt shingle roof, and repairs run $400 to $1,800. The city’s exposure to strong Santa Ana wind events through the Cajon Pass means wind-rated shingle installation and upgraded drip edge details are real considerations here, not upsells. Our Roofing quotes specify shingle layer count, underlayment type, and ventilation before the crew starts, with GAF and Owens Corning as named options.
Roof Replacement & Installation
Signs you need it
Shingles are curling or lifting after Santa Ana events, granules are collecting in gutters, or the roof is past its rated service life under Ontario’s UV load.
What it costs in Ontario
Roof replacement in Ontario runs $8,000 to $20,000, with the spread driven by square footage, shingle grade, and whether the existing layers must be removed.
How we do it
We document the existing layer count, strip to the deck, inspect the substrate, install the underlayment and wind-rated shingle system, and record the finished roof with photos.
Roof Repair
Signs you need it
You see water staining on ceilings, missing shingles after wind, or leaking around penetrations like vents and chimneys.
What it costs in Ontario
Roof repair in Ontario runs $400 to $1,800, and tile roof repair runs $600 to $2,500, depending on the extent of broken tiles and underlayment damage.
How we do it
We locate the source, document it with photos, replace the damaged shingles or tiles, repair the flashing, and test the repair before leaving.
What Roofing Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Roof Replacement | $8,000 - $20,000 |
| Roof Repair | $400 - $1,800 |
| Tile Roof Repair | $600 - $2,500 |
How often should a roof be inspected in Ontario?
After each significant Santa Ana wind season and at least once per year is the practical schedule for Ontario roofs, given the UV and wind exposure. Call (470) 298-9650 to schedule a free inspection with a written report.
Will my roof price change after work starts?
Not without a signed change order. If decking damage is found under the shingles, we document it, show you the photos, and price the repair in writing before proceeding. Call (470) 298-9650 for a quote.
Windows & Doors in Ontario


Window replacement in Ontario runs $4,500 to $15,000 for a typical full-house project, and impact window installation runs $8,000 to $25,000. Older north Ontario homes with original single-pane windows lose measurable cooling dollars every summer, and the Santa Ana winds argue for frames and hardware rated for higher wind pressures than a coastal install would require. Our Windows & Doors quotes name the frame material, glass package, and hardware before the crew arrives.
Window Replacement
Signs you need it
Frames are warped or rotting, glass is single-pane, or the windows rattle during Santa Ana events.
What it costs in Ontario
Window replacement in Ontario runs $4,500 to $15,000 depending on window count, frame material, and whether structural retrofitting is needed.
How we do it
We measure each opening, check the rough framing, install the new windows square and insulated, and document the installation with photos.
Impact Windows & Doors
Signs you need it
You want windows and doors that hold up under repeated Santa Ana wind loads or you want the noise and air-infiltration reduction that impact-rated assemblies provide.
What it costs in Ontario
Impact window installation in Ontario runs $8,000 to $25,000, with the spread driven by window count, size, and the specific wind-load rating required.
How we do it
We specify the wind-load rating for your exposure, order the rated glazing and frames, install with strapping and sealant per the manufacturer’s spec, and document the result.
What Windows & Doors Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Window Replacement | $4,500 - $15,000 |
| Impact Window Installation | $8,000 - $25,000 |
| Bathroom Vanity Installation | $800 - $3,000 |
How much does impact window installation cost in Ontario?
Impact window installation in Ontario runs $8,000 to $25,000 for a typical home, depending on window count and wind-load rating. Call (470) 298-9650 for a written quote, which is always free.
Do energy-efficient windows pay for themselves in Ontario?
In Ontario’s 105°F summers, low-E glazing and insulated frames reduce cooling load measurably, and many homeowners see the reduction on their first full summer bill. Call (470) 298-9650 to discuss specific glass packages.
Home Additions & ADU in Ontario

Home additions in Ontario run $45,000 to $130,000, and a detached ADU runs $90,000 to $220,000. The city’s expansive clay and adobe soils, particularly south toward Ontario Ranch, make post-tensioned engineered slabs a standard requirement that coastal contractors often underestimate. Our Home Additions & ADU work starts with a soils evaluation, a written foundation spec, and a flat price before anyone breaks ground.
ADU Design & Permitting
Signs you need it
You have a lot that can accommodate an ADU under Ontario’s development standards and want the design, engineering, and permit package handled as one scope.
What it costs in Ontario
ADU construction in Ontario runs $90,000 to $220,000, with the spread driven by size, site conditions, and the foundation spec required by the soils report.
How we do it
We hire the geotechnical engineer, design to the soil report, produce the permit drawings, submit to Ontario’s building department, and build to the approved plans with written change orders only.
Garage Conversion ADU
Signs you need it
You have an attached or detached garage with sound framing and want to convert it to living space without the cost of a new foundation.
What it costs in Ontario
Garage conversion in Ontario runs $30,000 to $80,000, depending on whether the slab needs structural work and how much utility work is required.
How we do it
We check the existing slab and framing, engineer any structural reinforcement, run utilities to code, insulate and finish the interior, and document every inspection.
What Home Additions & ADU Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Home Addition | $45,000 - $130,000 |
| ADU Construction | $90,000 - $220,000 |
| Garage Conversion | $30,000 - $80,000 |
What does it cost to build an ADU in Ontario?
A detached ADU in Ontario typically runs $90,000 to $220,000, and the single largest variable is the soils condition on your specific lot. Call (470) 298-9650 for a free estimate.
Will the price change once ADU work starts?
No. The foundation spec is engineered from the soils report before the quote is written, and any change requires a signed change order under The Haven Standard. Call (470) 298-9650 to discuss your project.

| Vinyl Fence Installation | $3,500 - $9,000 |
| Impact Window Installation | $8,000 - $25,000 |
What pushes a project toward the top of these Ontario ranges is usually the age of the home and what the walls reveal: old wiring, undersized plumbing, compromised subfloor, or clay soil that demands a heavier foundation spec. What does not change is the discipline: every quote is a flat written price with a written scope, and no work proceeds on a change until the change order is signed.
