How Much Do Basement Renovations in Ottawa Cost?

Generally, renovations don’t come cheap because of all the labour and materials they require. But basement renovations can be particularly costly because it adds value and additional usable space to your home (in case you want to sell it in the future).

There’s also a lot of foundational support located there which requires contractors and builders to be extra careful while working. This is why some of the best companies doing basement renovations in Ottawa come with certifications and years of experience.

You can always choose to do a DIY renovation project because it would be kinder for your budget in the long run. However, hiring an experienced contractor will mean the work will go more smoothly and within a set timeline.

To give you a general idea, a basic basement renovation contract between a full month to 60 days might already cost you $20000 up. But many factors can affect the final cost, including the size and shape of your basement, plus the renovation scope (see table below for reference).

Basement finishing (per sq. ft.) $65 -$100 per square foot
Basement remodelling$10000 – $30000 (depending on the number of features to be replaced)
Basement finishing package (per 1000 sq. ft.)$32000 up (inclusive of design, materials, labour, and clean-up)
Basement bathroom installation$10000 – $15000
UpgradesHardwood floor $7000 – $10000
Foundational expansion $10000 – $30000
System remodelling $1000 – $4000

Again, these figures are rough estimates based on most basement renovation contractors’ fees and costing. Bear in mind that small details like the price of drywall, framing, floor, and ceiling per square foot will all add up to the grand total.

Curious about how past customers found Ottawa General Contractors services? Read on:

“We had hired OGC in 2020 to turn a carport into a garage. Although the project started when the pandemic first came to Canada, we had some challenges that we thought could be avoided. These challenges have been addressed by upper management and we are satisfied with the final outcome. Thank you OGC for making it right!” – Tony D

“OGC completed my total home renovation and my experience has been great. They were always available to me (I can be very needy) and were always pleasant. The contracting teams were very polite and professional. An area for improvement could be dealing with the logistics of materials however my project did start during the pandemic so I was told that was the main issue. I would recommend OGC to my family and friends.” – Stearne L.
