What can a basement contractor do?

Basement Waterproofing

Finishing your basement takes a bit of planning. Before the drywall can go up, you’ll need to ensure that your interior and exterior basement waterproofing is intact. Your basement contractor will be able to check on this as well as install a reliable sump pump and dehumidify the space, if needed.

Crawl Space Decontamination

Unfinished crawlspaces are often damp, dark, and plagued with rodents and mould. Over time, it can impact your home’s structural supports and harm your health. To prevent moisture and pests from taking up residence in your crawlspace, your basement contractor will waterproof it, add a vapour barrier, and more!

Foundation Repair

A basement renovation project needs to be built on a good foundation. To prevent water from leaking into your basement during heavy rainfall or further damage to the structural integrity of your home, your basement contractor will repair all cracks in your foundation before moving forward in your project.

Basement Finishing

After all the preliminary steps have been taken care of, it’s time to start bringing your dream basement to life. From a guest suite to a home gym, your basement contractor will transform this once dark and empty space into something the whole family can enjoy!

Plumbing and Electrical

As the project progresses, you’ll need a set of skilled tradespeople, such as electricians and plumbers, to complete the rough-ins. Your basement contractor will coordinate everything for you to prepare for any upcoming installations.


If you plan on using your basement regularly, consider adding a bathroom for convenience – it’ll save you a trip upstairs! Your basement contractor will be able to install all the necessary elements to create a bathroom that meets your needs.

What to ask a basement contractor

Before the work begins, it’s important to meet with potential basement contractors. It’ll give you a chance to chat about your project and get a feel for them as a person. If you find that you get along better with one contractor versus another, trust that gut feeling – it’s a good sign! That said, we still suggest asking them at least some of the following questions to better understand what kind of work you’ll be getting into.

How much does a basement renovation cost?

A basement contractor’s rates will vary based on their experience, qualifications, and services offered. For example, some contractors offer full turnkey services (e.g., initial design to completion), while others specialize in certain trades like plumbing. In general, it’s best to go with a basement contractor that offers turnkey solutions to avoid potential headaches and budget issues.

Depending on the size of your basement, the materials you’ve selected, and how many labour hours are needed to get the work done, the cost of a basement remodel can be anywhere between $25,000 and $63,000 or $35 to $70 per square foot (not including a bathroom).
