Finished Basement Costs


If you have an unfinished basement in Ottawa, it’s time to change that. Keeping your basement incomplete is effectively wasting an entire room of your home. Sadly, basements are often the most underutilized room in many homes. We specialize in finishing basements at RenosGroup, so don’t wait to give us a call if you want to spruce things up. Beyond finishing your basement, we can also help you renovate and repurpose it.

There are lots of benefits involved with finishing your basement. These include:

  • Increased energy efficiency. If your basement isn’t finished, then it’s not insulated. As a result, cold and hot air escapes, making it harder to maintain the temperature in your home. Finishing the basement will insulate it, saving you money on your energy bill.

  • Increased value to your home. Finishing your basement can provide a 70% ROI due to the value it adds to your home. If you plan on selling your home in Ottawa, you owe it to yourself to hire us to finish the basement. A finished basement is often high on homebuyers’ wishlists. That can not only help your home sell for more but also faster.

  • Added versatility. You can use it as a bonus room when you stop neglecting your basement. We encourage homeowners to turn their basement into a room they wish they had. For example, do you want a home gym or hobby room? Then your basement is a perfect fit, but you need to finish it first!

Here’s an overview of what you can expect to pay for a finished basement:

  • $30,000 – $80,000 + HST for a basement 700-1,000 SF in length
  • $45-$85 per square foot
  • Lower square footage price includes basic finishes
  • Higher square footage price includes higher-end finishes & full bathroom
