Real transformations — not handyman work
Buildoreno is a Mississauga-based general contractor serving the GTA: kitchens, bathrooms, basement finishing, open-concept conversions, and home additions including second storeys. We design and build in-house under one project manager — engineered drawings, full permit handling, milestone-based payment, and a written warranty on every project. We focus on medium-to-large renovations ($25,000+), not handyman repairs.
One team from concept through permits, construction, and final walkthrough — no gap between the designer who drew it and the crew who builds it, and no trades pointing fingers.
Every estimate breaks out design, permits, structural, mechanical, finishing, and fixtures. You see where each dollar goes and can value-engineer line items without re-bidding.
Structural drawings, full building permits, committee-of-adjustment variances when needed — handled as part of the contract. We don't quote unpermitted work.

How much do renovations cost in the GTA?
GTA renovations span a wide range — most Buildoreno projects fall in the $25,000 – $200,000+ band. The three biggest drivers are structural scope (cosmetic vs. load-bearing vs. addition), material tier, and site complexity. Every estimate is a free, itemized written quote — design, permits, structural, mechanical, finishing, and fixtures all broken out.
| Project type | Typical size | Price range | What's included |
|---|---|---|---|
| Powder room refresh | 20–40 sq ft | $8,000 – $15,000 | Vanity, toilet, paint, flooring; no plumbing relocation |
| Full bathroom gut-and-finish | 40–60 sq ft | $25,000 – $60,000 | Tile, vanity, shower or tub, fixtures, plumbing as-is |
| Primary ensuite — premium | 60–120 sq ft | $45,000 – $85,000+ | Double vanity, curbless shower, premium fixtures |
| Kitchen — small refresh | Varies | $25,000 – $40,000 | Cabinets, counters, backsplash; layout unchanged |
| Kitchen — mid-range full reno | 150–250 sq ft | $55,000 – $85,000 | Most common GTA kitchen; possible wall removal |
| Kitchen — premium | Varies | $100,000 – $200,000+ | Custom cabinetry, premium appliances, structural |
| Basement finishing | 600–1,200 sq ft | $40,000 – $120,000 | Framing, electrical, plumbing, finishing |
| Rear or side addition | 300–800 sq ft | $150,000 – $400,000+ | Foundation, framing, MEP, finishing |
| Second-storey addition | 1,000–1,500 sq ft | $200,000 – $500,000+ | Reinforced foundation, new roof, full second floor |
| Whole-home renovation | Existing footprint | $250,000 – $800,000+ | Older GTA homes; varies with scope |
Pricing reflects typical GTA 2026 renovation rates. Toronto urban properties typically run 10–20% higher than equivalent suburban scope due to access constraints. Custom finishes, premium appliances, and complex structural work can shift pricing significantly. Every Buildoreno estimate is itemized — design, permits, structural, MEP, finishing, and fixtures are all broken out separately.
What else to coordinate
Big renovations rarely stay in one lane. These are the pieces worth folding into the same project — one team, one schedule, one mobilization instead of three.
Finishing a low basement? Underpinning gains the ceiling height to make it legal living space. We coordinate both under one permit and timeline — cheaper than doing them apart.
UnderpinningAdditions and second storeys need the roof tied in or replaced. We handle metal or flat roofing as part of the contract so the transition is detailed once, by one crew.
Metal & flat roofingMajor work disturbs grading, walkways, and planting. We fold landscape restoration into the project so the yard is put back right in the same mobilization.

Renovation questions, answered
Kitchen renovations vary significantly based on scope. A refresh with new counters, backsplash, and refinished cabinets might start around $25,000–$40,000. A full gut renovation with new layout, custom cabinets, and appliances typically ranges from $50,000–$100,000+.
We manage the entire permit process. This includes preparing drawings, submitting applications, scheduling inspections, and ensuring all work meets Ontario Building Code requirements. Permit costs are included in our quotes.
For most projects, yes—though comfort levels vary. Kitchen renovations are more disruptive than bathroom updates. We set up dust barriers, maintain access to essential areas when possible, and communicate daily schedules so you know what to expect.
Changes happen, and we have a clear process. Any scope changes are documented with a written change order that includes the cost and schedule impact before work proceeds. No surprises on your final invoice.
Timelines vary by scope: a bathroom renovation might take 3–4 weeks, a kitchen 6–10 weeks, and a full basement 8–12 weeks. Larger whole-home renovations can take 4–6+ months. We provide detailed schedules during the planning phase.
We offer both. Our design-build approach means one team handles everything from initial concepts through construction. This streamlines communication, reduces errors, and often saves money compared to hiring separate designers and contractors.
