Frequently Asked Questions

Common questions about Basement services in Aurora.

How much does a basement renovation cost in Aurora?

Basement renovations in Aurora range from $30,000–$55,000 for a standard finish to $60,000–$100,000+ for a legal apartment with separate entrance. Key cost drivers include: bathroom addition, ceiling height, waterproofing requirements, and egress windows.

Do I need a permit to finish my basement in Aurora?

Yes. In Aurora and across the GTA, finishing a basement requires a building permit. The permit process covers framing, electrical, plumbing, and insulation — all subject to inspection. We manage the permit process and schedule all required inspections.

What ceiling height is needed for a finished basement in Aurora?

Ontario Building Code requires a minimum ceiling height of 1.95 metres (6'5") for habitable basement space in Aurora. If your existing ceiling is lower, options include lowering the floor (underpinning) or creative design around beams and ductwork.

Do I need egress windows for a bedroom in the basement?

Yes. Ontario Building Code requires egress windows for any basement bedroom — minimum 0.35 m² openable area and no dimension smaller than 380mm. Egress windows are required for legal occupancy and for insurance coverage. We handle the installation as part of our basement renovation service.

Can I legally rent out my finished basement in Aurora?

To legally rent a basement apartment in Aurora, it must meet Ontario Building Code requirements: separate entrance, proper ceiling height, egress windows, interconnected smoke and CO detectors, and a second means of egress. We build legal secondary suites that meet all requirements.

How do I deal with moisture in my basement before renovating?

Moisture must be addressed before any finishing work begins. We assess the source — whether exterior drainage, foundation cracks, or condensation — and recommend waterproofing solutions. Finishing over a wet basement leads to mould and material failure.

What insulation should I use in my basement in Aurora?

In Aurora's climate, basement walls should have a minimum of R-20 insulation. We typically use rigid foam board (XPS) against the foundation wall, then batt insulation in the stud wall. This approach prevents thermal bridging and moisture accumulation.

How long does a basement renovation take?

A standard basement finish in Aurora takes 6–10 weeks from permit approval to final inspection. A legal basement apartment with plumbing, separate entrance, and multiple rooms takes 10–16 weeks. We provide a detailed schedule at the start of every project.

What's the best use for a finished basement in Aurora?

The most popular uses in Aurora are: legal rental apartment (best ROI), family recreation room, home office, home gym, and guest suite. The right choice depends on your family's needs, budget, and long-term plans for the property.

How much value does a finished basement add to my home in Aurora?

A well-finished basement in Aurora typically adds 70–80% of renovation cost in home value, with legal apartments often returning more. In the current Aurora market, a legal secondary suite can add $80,000–$150,000 to your home's appraised value.
