The Adept approach
One crew.
One quote.
Code-smart basements.
Basement renovations go wrong when mechanicals, insulation, and permits are sequenced as afterthoughts. We run the full scope - rough-in through finishes - with one accountable team and a fixed price agreed before we open walls.
- Written scope, allowances, and timeline before you commit
- Licensed plumbing and electrical partners coordinated in-house
- Dust control and daily clean-up - built for families living upstairs
What's included
Everything in your GTA basement renovation - in one quote
One crew coordinates framing, mechanicals, and finishes so you are not juggling separate trades. Every line item below is priced before we start your basement renovation.
Layout planning for living space, home office, gym, rental suite, or multi-room basement renovations
Framing, fire separation, and sound-conscious details where code or comfort requires them
Insulation, vapour control, and moisture-smart sequencing before drywall
Egress windows and compliant stair details coordinated with permit drawings when applicable
Rough and finish electrical via licensed partners - lighting, circuits, panels as scoped
Rough and finish plumbing for basement bathrooms, laundry, or wet bars via licensed partners
Drywall, ceilings, trim, doors, and flooring coordination through paint-ready
Permit coordination flagged up front - no surprise scope after framing starts
How it works
Your GTA basement renovation, step by step
Predictable milestones, inspection-ready sequencing, and one point of contact from start to finish.
01
Site visit & code check
We measure ceiling height, utilities, and existing structure, then walk through layout, egress, and bathroom or bar options so basement renovation cost drivers are clear early.
02
Fixed-price quote
You receive a written basement renovation price and schedule - allowances and permit assumptions spelled out, not buried in fine print.
03
Rough-in & inspections
Framing, mechanicals, and insulation sequenced for inspection milestones where required - debris managed and stairs kept safe if you are living upstairs.
04
Drywall & finishes
Board, mud, prime, then floors, trim, cabinets, and fixtures - one accountable crew through paint and hardware.
05
Final walkthrough
We test outlets, valves, and doors with you, address punch items, and leave the basement renovation move-in ready.
“Responsible team, no need to babysit them. In fact they delivered more than I had agreed to, without increasing the price.
I definitely recommend them!”

Common questions
GTA basement renovation FAQs
- How long does a basement renovation in the GTA take?
- Most GTA basement renovations we complete run 6–12 weeks depending on scope. A straightforward finish with open layout and no new bathroom often lands in six to eight weeks. A full suite with bathroom, kitchenette, and permit inspections typically runs ten to fourteen weeks. You receive a written timeline before work starts.
- How much does a basement renovation cost in the GTA?
- Basement renovation costs in the GTA commonly range from about $45–$75 per square foot for a basic finish with quality materials to $100+ per square foot for a legal secondary suite with bathroom, kitchen, and upgraded finishes. A typical whole-basement GTA project lands between $50,000 and $95,000. Drivers include new plumbing stacks, egress, ceiling height fixes, and finish grade. We provide a fixed-price written quote after a site visit.
- Do basement renovation permits vary across GTA municipalities?
- Yes. Toronto, Mississauga, Vaughan, Markham, Richmond Hill, Brampton, and Oakville each run their own building department with slightly different submission requirements, review timelines, and inspection scheduling. New plumbing stacks, added circuits, structural changes, and egress windows generally require a permit in every GTA municipality. As part of every basement renovation quote, we identify which permits apply and coordinate the submission with the relevant city.
- Do basement renovations need a permit in Toronto?
- Often yes. New or moved plumbing, additional circuits, structural changes, new dwelling units, and egress window installs typically require a permit in Toronto and most GTA municipalities. We flag permit needs during the scope walk and include compliant work in the quote.
- Can we live upstairs during a basement renovation?
- Yes - most GTA clients stay in the home during a basement renovation. We isolate dust, protect main-floor traffic paths, and schedule noisy work in predictable blocks. Stairs and mechanical access stay usable unless a short shutdown is planned with notice.
- Which GTA municipalities do you serve for basement renovations?
- We perform basement renovations across Toronto and the wider GTA including Mississauga, Vaughan, North York, Etobicoke, Scarborough, Richmond Hill, Markham, Brampton, Oakville, and Burlington. Travel and service area are included in our quotes - no surprise mileage fees by municipality.
