Trusted Home Renovation for Ontario Homeowners
Our Home Renovation in Ontario typically costs between $9,000 for a small bathroom remodel and $130,000 for a full home addition, with most kitchen remodels landing in the $14,000 – $45,000 range. Workshop Contractors handles the entire scope, from roofing and windows to kitchens, baths, and ADU additions, under one contract and one schedule. Noel Figueroa leads a team that has built its reputation in Ontario by managing the material sourcing, the labor, and the permits so homeowners aren’t stuck coordinating multiple specialty crews.

Home Renovation Contractors
Home Renovation Contractors are licensed general contractors who manage the full scope of a remodel, including structural work, mechanical systems, finishes, and exterior upgrades, rather than specializing in a single trade. You need one when your project spans multiple systems, like a kitchen remodel that touches plumbing, electrical, cabinetry, and countertops. Workshop Contractors operates as a licensed general contractor, which means we source materials directly from brands like Caesarstone and Kohler and install them with our own crews, keeping accountability in one place instead of scattered across subcontractors. Kitchen remodels in Ontario run $14,000 – $45,000, while bathroom remodels range $9,000 – $28,000.
Structural and Envelope Coordination
Roof replacements in Ontario cost $8,000 – $20,000, and when we handle that alongside interior work, we sequence trades so the drywall isn’t finished before the old roof comes off. Homeowners don’t always realize how much a roofing tear-off can shake dust into living spaces. We plan for that sequencing and protect the interior before we start overhead.
Single Contract Accountability
When a homeowner hires separate contractors for windows, siding, and a kitchen, the finger-pointing starts the moment two scopes overlap. With Workshop, one contract covers the whole project. If a window rough opening is off by half an inch, we fix it before the siding crew ever shows up, because both scopes are ours.
Styles & brands we work with







Home Renovators
Home Renovators are the people and companies who turn an existing house into a better-functioning one, through demolition, reframing, systems replacement, and finish work. In Ontario, homeowners bring us in when a house built in the 1970s or 80s needs a layout change, updated plumbing and electrical, or a modern kitchen and bath that matches how the family actually lives now. Workshop Contractors is a true general contractor, so our home renovators handle the exterior envelope and the interior remodel as one integrated job, similar to our Home Renovation in Chino approach. A whole house renovation in Ontario usually costs $45,000 – $130,000 depending on the square footage and how much structural work is involved.
Material Sourcing In-House
We source and we install. That distinction matters because most renovators hand you a list of materials and tell you to go shopping. Instead, our team works with KraftMaid and Wellborn cabinetry, Cambria and Caesarstone countertops, and Kohler and Moen fixtures, so material availability and lead times are our responsibility, not yours.
Existing Home Complications
Older Ontario homes, especially in the neighborhoods off Euclid Avenue, hide surprises behind the walls. Galvanized supply lines are corroded. Electrical panels are undersized. Floor joists have been notched over decades of DIY repairs. We budget for those discoveries and communicate the costs as they surface, which is why our estimates are detailed and our change orders are rare.
Home Improvement Contractors
Home Improvement Contractors handle upgrades that make a house more comfortable, efficient, and valuable, whether that means a new paver patio, a full window replacement, or a garage conversion. You need one when the project involves more than a single trade and needs permits, engineered plans, or product knowledge across multiple categories. Workshop Contractors serves Ontario homeowners who want exterior and interior improvements handled by one company rather than a sequence of specialists. Paver patios in Ontario run $3,500 – $11,000, window replacements cost $4,500 – $15,000, and a garage conversion falls between $30,000 and $80,000.
Exterior Improvements with Interior Impact
A vinyl fence installation at $3,500 – $9,000 seems separate from a kitchen remodel until you think about where the fence crew parks and hauls materials. Since we run both scopes, we sequence the work so the fence goes in before the kitchen phase starts, reducing dust and site congestion. That’s what single-source coordination looks like in practice.
Brand-Tier Flexibility
Some clients in Ontario want Blanco sinks and Grohe fixtures. Others want solid, cost-conscious alternatives that still hold up. We carry relationships across both tiers in the same product categories, so the conversation is about trade-offs, not upsells. You choose where to spend, and we guide you with material knowledge from hundreds of installed projects.
Home Renovation Companies
Home Renovation Companies range from small two-person operations to full-scale general contractors, and the difference shows up in how material failures, permit delays, and scheduling conflicts get handled. The moment you’re spending $20,000 or more on a kitchen, you want a company with established vendor relationships and enough project volume to pull crews when a phase runs long. Workshop Contractors sits on the full-service end of that spectrum, with vetted partnerships across 50+ name-brand manufacturers. Our Ontario pricing is consistent: bathrooms at $9,000 – $28,000, kitchens at $14,000 – $45,000, and roof replacements at $8,000 – $20,000.
Manufacturer Access Without the Showroom Markup
Because we order directly through our trade accounts with brands like Moen, Kohler, and Caesarstone, we bypass the retail showroom markup that gets baked into most renovation bids. That doesn’t make us the cheapest option in Ontario, but it means more of your budget goes into the materials and labor, not a middleman’s margin.
Prefab and ADU Capability
Unlike our Home Renovation in Upland, most home renovation companies in the Inland Empire can’t touch an ADU project. Workshop Contractors has established relationships with prefab manufacturers including Abodu, Dvele, Mighty Buildings, Boxabl, and Plant Prefab, which gives Ontario homeowners a genuinely different path for accessory dwelling units that typically cost $90,000 – $220,000 when built as additions on site.
Renovation Contractors
Renovation Contractors are the professionals responsible for executing a remodel, from pulling permits and scheduling inspections to installing finishes and managing the punch list. In Ontario, the right renovation contractor is the difference between a kitchen that takes six weeks and one that drags into month four. Workshop Contractors manages every trade on your project, and we’re structured so that the roofing crew, the window installers, and the cabinet finishers all answer to the same project manager. Typical renovation scopes in Ontario include bathroom remodels at $9,000 – $28,000 and driveway replacements at $5,000 – $14,000.
Permit and Inspection Handling
Ontario building codes cover structural changes, electrical work, plumbing reroutes, and roofline alterations, and the city’s inspection process is unforgiving if the paperwork isn’t right. We pull the permits, schedule the inspections, and stand behind the work when the inspector walks through. Our clients don’t track down the building department; we do.
Timeline Realism from Experience
We don’t promise 30-day kitchen remodels, because real renovation work in Ontario rarely moves that fast when inspections, material lead times, and trade sequencing are involved. What we do promise is accuracy. When we scope a whole house renovation, we build the schedule around the materials we’ve already confirmed, not the ones we hope will arrive on time.
Whole House Renovation
Whole House Renovation means renovating the entire home at once rather than room by room over several years, and it’s the right call when a property needs systemic upgrades across plumbing, electrical, insulation, windows, and finishes. Ontario homes built before 1990 often hit a tipping point where piecemeal repairs start costing more than a coordinated gut and rebuild of the interior. Workshop Contractors manages whole house renovations as a single project with one schedule, which means the family can move out once, move back in once, and not live through three years of construction. These projects typically range from $45,000 to $130,000 depending on the home’s square footage and condition.
Exterior and Interior in Sequence
From the roof down to the pavers, we handle it. A whole house renovation in Ontario that starts with a roof replacement at $8,000 – $20,000 and then moves through windows at $4,500 – $15,000 needs careful sequencing so each phase protects the last. Since we manage the entire envelope and the interior, we don’t have to negotiate with another contractor about who’s responsible for water intrusion during a rainstorm.
The Hidden Systems Most Homeowners Miss
Most homeowners don’t realize how many systems interact. Moving a kitchen island means rerouting drain lines. Adding a bathroom means upsizing the water heater. Changing a window size means reframing the wall and redoing the exterior siding around the new rough opening. We plan for those intersections during the design phase, not the week before demolition, so the budget doesn’t surprise anyone mid-project.
Brands We Service
We work extensively with Caesarstone countertops across kitchen and bath projects in Ontario. Their quartz surfaces hold up well against the hard water and daily wear common in this area, and we’ve installed enough of their product line to know which finishes show scratches and which ones hide them. When a client wants Caesarstone, we order directly through our trade account, avoiding retail markup.
For plumbing fixtures, we install Kohler and Moen products across most remodels, from kitchen faucets to full bathroom suites. Kohler’s valve systems and Moen’s cartridge designs are both reliable, but they have different service profiles, and we walk homeowners through that trade-off before anything gets ordered. For sinks and workstation setups, Blanco comes up frequently in Ontario kitchens where homeowners want a single bowl deep enough for oversized pots and baking sheets. Whether you have these brands or any other make, we can help you plan, source, and install the full scope.

- Multiple systems failing at once. If the roof leaks during winter storms and the kitchen sink drains slow, the issues may share a cause, like failing flashing or a settling foundation. A professional renovation contractor can diagnose the root cause instead of patching symptoms one at a time.
- Noticeable floor slope or sticking doors. In Ontario homes built on expansive clay soil, slab movement can cause door frames to bind and floors to develop a visible pitch. A general contractor can assess whether it’s a structural issue or simple settling before you invest in cosmetic finishes.
- Water stains on ceilings or around windows. Stains mean water is getting in somewhere, and by the time the stain shows, the leak has usually been active for months. Roof repair in Ontario runs $400 – $1,800, which is far less than the cost of replacing rotted framing and moldy drywall later.
- Electrical panel is warm to the touch or repeatedly tripping. An undersized panel can’t support modern kitchens with double ovens and induction cooktops. Since panel work is both dangerous and permit-required, it’s a job for a licensed professional, not a weekend project.
- Layout no longer works for your household. When the kitchen is cut off from the living area and the only bathroom sits off the primary bedroom, the home’s floor plan is costing you daily. A whole house renovation addresses the flow problem instead of forcing another year of awkward compromises.
Our Process, Step by Step
- 1
Initial consultation and site walkthrough. We walk the property with you, room by room, and talk through what’s working, what isn’t, and what the renovation has to accomplish. This is where we identify structural constraints, existing material conditions, and which scopes need permits.
- 2
Detailed scope and line-item estimate. We put every trade, material, and allowance on paper, with the Ontario market prices we’ve calibrated across hundreds of local projects. You’ll see what the kitchen cabinets cost, what the plumbing rough-in costs, and what the roof replacement costs, as separate lines.
- 3
Material selection through our vendor network. Since we source directly from brands like Caesarstone, Kohler, and Moen, material selection happens in-house. You’re not driving to three different showrooms. We bring samples and pricing, and we guide the trade-off conversation from real installation experience.
- 4
Permitting and inspection management. We pull the permits, schedule the inspections with the City of Ontario, and walk the project through every required checkpoint. Any corrections the inspector flags get fixed on our timeline and our dime, not passed back to you as a surprise change order.
- 5
Sequenced construction and final walkthrough. Trades are scheduled in the order that protects finished work, so paint goes on after drywall dust settles, and flooring goes in after the heavy equipment clears the site. We finish with a punch list walkthrough so every detail gets addressed before we call the project complete.
How Much Does Home Renovation Cost in Ontario?
A typical kitchen remodel in Ontario runs $14,000 – $45,000 depending on cabinet grade, countertop material, and whether walls move. A small bathroom remodel usually lands between $5,000 and $12,000, while a full bathroom with a walk-in shower runs $9,000 – $28,000. Whole house renovations start around $45,000 and can reach $130,000 for larger homes with structural changes. If you’re adding square footage, expect $45,000 – $130,000 for a home addition or $90,000 – $220,000 for an ADU. Exterior projects carry their own ranges: roof replacement at $8,000 – $20,000, windows at $4,500 – $15,000, and paver patios at $3,500 – $11,000.
What affects the price most is the existing condition of your home. Older Ontario properties off Euclid Avenue or near the 60 freeway frequently need electrical panel upgrades, plumbing replacement, or structural shoring that newer homes don’t. The other big variable is material tier, and that’s a choice you control. Cambria and Caesarstone countertops cost more than standard quartz or solid surface, but they also hold resale value and resist staining. To avoid overpaying, get a line-item estimate that separates labor from materials and shows exactly where every dollar goes.

Frequently Asked Questions About Home Renovation in Ontario
Home renovation is the process of improving an existing home through structural changes, systems upgrades, and finish replacements rather than building new construction. In Ontario, that typically means kitchen and bathroom remodels, whole house renovations, roofing and window replacement, and additions or ADUs. Workshop Contractors handles both the exterior envelope and interior remodeling under one contract, so one team manages every trade from demolition through final inspection, just as we do with Home Renovation – Montclair.
A bathroom remodel usually takes 3 – 6 weeks, a kitchen remodel 6 – 12 weeks, and a whole house renovation 3 – 6 months depending on scope and permit review times. Material lead times also affect the schedule, which is why we confirm products are in stock or on order before we set start dates. Ontario’s permit office typically reviews residential renovation applications within 2 – 4 weeks, and we handle that paperwork as part of our scope.
Kitchen remodels range $14,000 – $45,000, bathroom remodels $9,000 – $28,000, and whole house renovations $45,000 – $130,000 in the Ontario market. The price depends on your home’s existing condition, the material tier you choose, and how much structural work is required. Call (844) 384-3361 for an exact quote, and the estimate is free.
Yes, we source and install Caesarstone countertops, Kohler fixtures, Moen fittings, and Blanco sinks across kitchen and bath remodels in Ontario. We buy directly through our trade accounts, which means you get trade pricing and we take responsibility for delivery timelines and installation fit. If you’re considering a different brand, we can work with that too, since we’re not locked into any single manufacturer.
For urgent structural issues like active roof leaks, water intrusion, or failed support members, call us at (844) 384-3361 and we’ll assess whether the situation needs immediate attention. Water damage spreads quickly in Ontario’s summer heat, and a temporary repair now can prevent a much larger renovation later. Roof repairs run $400 – $1,800, and we’ll tell you honestly if a full replacement is the better long-term move.
Our workmanship warranty covers installation defects, and we stand behind the materials we source through our manufacturer relationships. Product warranties from brands like Kohler, Moen, and Caesarstone cover their specific components, and we handle the warranty claim process if a material fails. Noel Figueroa and the Workshop Contractors team are accountable for every trade we install.
Clear the rooms being renovated of personal belongings, arrange for a temporary kitchen or bathroom if yours will be offline, and confirm where crews will park and stage materials. We’ll walk you through a pre-construction checklist before demolition starts so there are no surprises on day one. The more decisions you finalize before construction begins, the smoother the schedule runs, and we help you lock those down during the design phase.
