Should you Invest in Construction of Basement Walkout?

Benefits of Basement Walkout Construction Toronto & GTA

Basement walkout construction is a popular option for property owners that are looking to add extra convenience to their homes. It is one of the steps to potentially turn your basement into a separate unit so you & people who live in the basement floor can enjoy your own separate space. Basement walkout construction comes with a number of benefits, here is a couple of examples:

  • Property Convenience – basement walkout will make your whole house more usable and convenient for your family and people who live on the basement floor.

  • Extra Entrance – having the freedom to come in and go out at any time without any disturbance is often named one of the biggest benefits of basement walkout construction.

  • Full-Size Windows – nothing beats the natural light. Basement walkout construction can include adding full-size windows to your basement. As a result, your basement can get access to more natural light.

  • Improved Ventilation – walkout basements often have better air circulation compared to below-grade basements, which can sometimes feel damp or stuffy. The ability to open windows or doors in a walkout basement allows for better ventilation, helping to reduce humidity and musty odors commonly associated with below-grade spaces. This can contribute to a healthier indoor environment.

  • Increased Property Value - adding a walkout to your basement can potentially increase the value of your home. The additional living space, improved functionality, and enhanced aesthetics are attractive features for potential buyers. It can make your property stand out in the market and may contribute to a higher resale value.


Basement walkout construction can bring unparalleled benefits to your property. However, it is important to consider local building codes, permits, and consult with professionals such as architects or contractors to ensure the feasibility and safety of adding a walkout to your basement.

Planning the Basement Walkout in Toronto

Process of Basement Walkout Construction

The process of basement walkout construction will vary depending on the specifics of your property, requirement, location and other factors. Here is an example of a relatively simple, standard basement walkout construction project:


  1. Excavation & Demolition – once your property has all the necessary permits and paperwork from the City, it is time to prepare for the basement walkout construction. Depending on the level of access our team will use an excavator or will otherwise do all the excavation work manually. Next – footings will be formed so we can get a sign-off from the City or an engineer. Once the sign-off is received the team will start pouring the the footings.

  2. Block Work – after the footings get enough curing time, the team will shift to laying new concrete block work.

  3. Waterproofing & Parging – multiple layers of the waterproofing membrane will be applied to the walls in order to prevent moisture from intruding inside the perimeter walls.

  4. Drainage System Installation – weeping tiles will be installed following all the requirements to keep the weeping tile clear of debris. If required sump pump can be installed as well.

  5. Concrete Stairs & Landing – after all the necessary preparation work is complete, the team will pour the concrete stairs and landing to prepare the basement walkout.

  6. Finishing the Work – handrails, basement door openings, landscaping, and retaining walls are installed (if required) to give your basement a good look.


While the details vary, one thing is always the same – you need to get quality workmanship from a reputable basement walkout contractor.

What Our Clients Say?


Stephanie G.

Residential Client

I used Aquamaster for two separate home waterproofing projects and I was extremely satasified with their work and price. Their team are highly skilled, thorough and were able to complete the 10.5 hour job in one day. They were even kind enough to seal my window frame after I noticed a minor leak. I would highly recommend Aquamaster for all your waterproofing and plumbing needs.

The Aquamaster team is absolutely fantastic! They went above and beyond to diagnose and correct the problem that I had with my basement plumbing caused by old pipes and persistent tree roots. I used them once in 2012 and in 2020. I cannot say enough good things about this team - Highly recommend.
