Luxury finished basements & rental suites in Toronto & the GTA West
If you’ve been searching basement renovation, finished basement, basement renovation near me or cost to redo basement and still don’t have a clear plan, you’re not alone. We help GTA homeowners turn those searches into a realistic scope, budget, and timeline for a finished basement they’ll actually use.
Who we work with
When does a basement renovation make sense?
Many of our clients land here after weeks of Googling things like “basement renovation near me,” “finished basement ideas,” “basement contractors near me” or “basement reno cost.” This page is for you if any of the situations below sound familiar.
You have an unfinished basement and want to turn it into usable living space — a family room, gym, office or kids’ zone — instead of storage.
You’re exploring a legal basement apartment to generate rental income and need a team that understands Ontario Building Code, egress and sound separation.
You’re comparing a lighter basement remodel versus a full gut and keep searching “cost to redo basement” or “basement renovation price” without clear answers.
You’re dealing with an older, low-ceiling space and considering an underpinned basement or basement walkout, but aren’t sure what’s realistic for your home.
You’ve talked to a few basement finishing contractors or “one-week basement” companies and want a more design-led, carefully detailed approach.
Our process
Our design–build process for basement renovations in the GTA
A basement renovation has its own set of challenges — head height, moisture, temperature, insulation, code requirements, sometimes underpinning or walkouts. Our role is to manage all of that under one roof, instead of leaving you to coordinate separate basement contractors, engineers and trades.
1
Discovery & walkthrough
We start by understanding how you’d like to use the basement — family space, guest suite, rental unit, gym, office — and review the existing structure and mechanical systems. During the walkthrough, we’ll look at ceiling heights, windows, access and any obvious moisture concerns.

Concept layout & rough budget
Our design team prepares layout options for your finished basement, including ideas for bedrooms, bathrooms, storage, laundry and, if relevant, a separate entrance. We pair this with a rough basement renovation price range based on similar projects in Toronto and the GTA.

Detailed design & specifications
Once the direction is agreed, we finalise the plan, including walls, doors, plumbing, electrical, subfloor, insulation, heating, lighting and finishes. For basement suites, we also plan kitchens or kitchenettes, egress windows and fire separations to align with code and municipal requirements.

How we think through every part of your basement
A successful basement renovation is about more than new flooring and drywall. It’s about comfort, safety, code compliance and a layout that makes the space feel like part of the home instead of an afterthought. Here’s how we break it down.
Layout, head height & egress
We plan walls, doors and room sizes around head height, natural light and code requirements for bedrooms and exits. That includes discussing options like egress windows, basement walkouts and, where needed, underpinning to increase ceiling height.

Moisture, insulation & subfloor
Basements behave differently than upper floors. We address moisture, temperature, insulation, vapour control and subfloor for basements so the finished space feels warm and dry, not damp and chilly.

Focus on comfort, safety & code
From moisture and insulation to egress, fire separation and sound control, we treat basements as serious living space, not just bonus square footage. That’s especially important if you’re planning a basement rental suite.

Frequently Asked Questions
Questions we’re often asked about basement renovations
How much does it cost to finish a basement in Toronto?
Costs vary depending on size, existing conditions and whether you’re creating a simple family space or a full basement suite. Many basement renovations in Toronto and the GTA fall into broad ranges, which we’ll walk through with you. Early on, we’ll give you a realistic basement renovation price range based on similar projects so you’re not guessing.
What affects basement renovation cost the most?
Key drivers include whether the basement is already partially finished, the number of bathrooms, whether you’re adding a kitchen or laundry, ceiling height changes (like underpinning), and the level of finishes. When people Google “cost to redo basement” or “basement reno cost”, they usually see one number; we prefer to explain the levers behind that number.
Do I need a permit to finish my basement?
In many cases, yes — especially if you’re adding bedrooms, bathrooms, changing structure or creating a legal basement apartment. We can guide you on when permits are required and handle drawings and submissions as part of the project.
How long does a basement renovation usually take?
Timelines depend on complexity. A straightforward finished basement with no structural changes is much faster than an underpinned basement with a walkout and suite. Once your scope is defined, we’ll outline an expected schedule for design, permits and construction.
Can you help decide between a family basement vs. a rental suite?
Yes. Some homes are better suited to a family rec room or home office, others make more sense as a basement rental unit. We’ll discuss your goals, budget and the constraints of your property to help you choose a direction that fits.
Why hire a basement renovation contractor instead of coordinating trades myself?
Finishing or remodelling a basement involves design decisions, permits, inspections, plumbing, electrical, framing, drywall, flooring and more. Working with a dedicated basement renovation contractor means one accountable team manages all of that, reducing the risk of delays, missed steps and moisture or code issues later.
