"From the initial consultation to the final walkthrough, the team was professional, clean and on time every single day. Our basement went from a dark storage room to our family's favourite room in the house — with a home theatre, a bar and a full bathroom. The fixed pricing meant we never had to stress about the budget. Highly recommend NorthBridge to anyone."

FAQ

How long does a basement renovation take in Ottawa?

A standard basement finish typically takes 6–10 weeks depending on size and complexity. A basic finish (framing, drywall, flooring, electrical) runs 4–6 weeks, while a full basement with a bathroom, bar and complex finishes may take 8–12 weeks. Your timeline is locked in the fixed-price agreement.

Do I need a permit for a basement renovation in Ottawa?

Most basement renovations in Ottawa require a building permit, especially if you're adding a bathroom, legal suite, or making structural changes. We handle the entire permit application process on your behalf — it's included in your fixed-price quote so there are no surprise fees.

How much does a basement renovation cost in Ottawa?

Basement renovations in Ottawa typically range from $35,000 for a basic finish to $80,000+ for a full legal suite or high-end entertainment space. The main cost drivers are square footage, bathroom additions, and finish selections. We provide a detailed, fixed-price quote after your free consultation.

Can you build a legal basement suite in Ottawa?

Yes. We build legal secondary suites that meet Ottawa's zoning requirements and building code — including proper egress windows, fire separations, separate entrances, and all necessary inspections. A legal suite can add $1,800–$2,500+ per month in rental income to your household.

What do you do about moisture and dampness in Ottawa basements?

We assess your basement for moisture issues before framing begins. Where required, we apply vapour barrier membranes, install proper drainage, and use moisture-resistant materials. We do not skip this step — addressing moisture properly is the foundation of a long-lasting basement finish.

Can I stay in my home during a basement renovation?

Absolutely. Basement renovations are the least disruptive type of renovation — our crew works entirely below grade and the rest of your home is unaffected. We use dust barriers and clean up thoroughly at the end of every workday.
