Home Renovations in Toronto & the GTA

Transform the home you already love.

Not every dream home means starting from scratch. Sometimes the smartest investment is reimagining the home you already own. For over 30 years, GrandBuild Homes has helped GTA homeowners turn dated, cramped, or worn spaces into refined, high-performing homes built to last.

As a family-run, HCRA-licensed and Tarion-backed builder, we bring the same discipline, craftsmanship, and total accountability to renovations as we do to our custom builds—managing design, permits, construction, and finishes through one accountable team across Mississauga, Toronto, Oakville, Vaughan, Brampton, Caledon, Richmond Hill and the GTA.

Luxury Home Renovations

GrandBuild Homes delivers luxury home renovations across Mississauga, Toronto, Oakville, Vaughan, Brampton, Caledon, Richmond Hill and the Greater Toronto Area. Whether you’re modernizing a single room or transforming your entire home, we turn tired, dated spaces into refined, high-performing homes built to last.

We design and build with the same discipline as a new custom home—protecting structural integrity, improving flow, and elevating every finish. Every renovation is carefully planned, engineered, permitted, and constructed by one accountable team, so the result feels seamless and intentional.

Our process is ideal for homeowners who want to improve how their home looks, feels, and functions—without compromising on quality, comfort, or long-term value.

Whole-Home Renovations: A complete transformation, room by room. We reconfigure layouts, upgrade structure and systems, and elevate every finish—turning an outdated house into the home you’ve always wanted, without the cost of building new.

Kitchen & Bathroom Renovations: The rooms that define daily life, rebuilt to the highest standard—custom cabinetry, stone surfaces, premium fixtures, and lighting that’s as durable as it is beautiful.

Basement Finishing: Unlock your lower level as refined living space—a family room, home theatre, gym, or guest suite—built warm, dry, and to code with the same finish quality as the rest of your home.

Heritage & Restoration: Character homes deserve careful hands. We restore and modernize period properties with respect for their original detail, pairing timeless craftsmanship with today’s comfort, efficiency, and code.

Working Process

How We Work

Every renovation follows the same disciplined process that defines our custom builds. We begin with a discovery call and feasibility review, move into design and a fixed, transparent budget, then handle permits and approvals. From there we build with hands-on site supervision and clear communication at every stage—right through to a detailed final walkthrough. One accountable team, from first sketch to finished home.

Solutions & Benefits

Every engagement starts with a clear scope and a realistic budget — then we protect both with disciplined planning, transparent reporting, and hands-on oversight from start to finish.

Process in Action

Frequently Asked Questions

We’ve become the best at what we do by being transparent, available, and accountable. Here are the questions our clients ask most.

How much does a home renovation cost in Toronto & the GTA?

Renovation costs depend on scope, size, and finish level—a single bathroom is very different from a whole-home transformation. Rather than quote a vague range, we provide a clear, fixed budget after a discovery call and feasibility review, with no hidden costs.

Will my renovation match the rest of my home?

Absolutely. Whether we’re updating a single room or the whole house, we carry materials, millwork, and finishes through the project so the renovated areas feel intentional and cohesive—never patched on.

Do I need a permit for my renovation?

Many renovations do—especially when you change layouts, structure, plumbing, or electrical. We manage the full approval process for you: drawings, permit submission, inspections, and final sign-off, so everything is done properly and to code.

Can we live in the house during construction?

In most cases, yes. We plan the build to keep the existing home sealed, safe, and livable for as long as possible, and we walk you through exactly what to expect at each stage.
