Why domilya for your basement

Most basements weren't built to be lived in. We fix that first.

Low ceilings, ductwork in the wrong place, damp corners, windows too small for a bedroom. Before we talk finishes, we check ceiling height, moisture, HVAC access and egress, so the design works in your basement and passes inspection the first time.

Then one team handles everything: design, permits, framing, plumbing, electrical, HVAC, insulation, drywall, flooring and finishes. One project manager, no subcontractor hand-offs.

Client story

A 1,700 sq ft basement, built for the whole family.

This family had a large, unfinished basement and wanted to turn it into living space. We designed a rec room, a bar, a home gym and a new washroom, and let them walk through the design in VR goggles before construction started. Inspectors signed off each stage as the work went.

Rachid and his team have just completed our basement reno, which included cutting out a door, two windows and creating a separate entrance… They also had beautiful design ideas and did top quality work. I'm thrilled with the outcome.

FAQ

Basement Renovations questions.

Can't find your answer? Our team is happy to talk it through, with no obligation.

Ask a question →
How much does a basement renovation cost?

It depends on scope. A finished family space costs less than a legal second unit with a separate entrance, kitchen and bathroom, and ceiling height, plumbing and finish level all move the number. After your free consultation you get a detailed line-item quote, so you can see where every dollar goes.

How long does a basement renovation take?

Most basement renovations take 10–16 weeks. Legal suites with plumbing and separate entrances are on the longer end. Your project manager gives you a detailed timeline before work begins.

Do I need a permit to finish my basement?

Yes. The Ontario Building Code requires permits for basement work involving framing, plumbing, electrical or structural changes. Legal suites have additional requirements, including fire separation and egress windows. We handle all permits and inspections.

Can you build a legal basement suite?

Yes, legal basement suites are one of our specialties. We handle the full process: separate entrance, kitchen, bathroom, bedroom, fire separation, egress windows and every inspection your municipality requires.

Can I rent out my basement suite?

Once it's built to code and passes inspection, yes. Burlington, Oakville and Milton each have their own rules for additional residential units, and we design to meet them from the start.

What areas do you serve?

We're based in Burlington and work across Oakville, Milton, Mississauga, Etobicoke, Waterdown, Ancaster, Dundas, Georgetown, Halton Hills and Guelph. Free in-home consultations are available throughout our service area.
