What you can do with your basement renovation

Basement renovations are useful projects not only because they can clean up the space and create more room for storage, but they can be transformed into different rooms with entirely new features. Whether you’re looking for smaller-scale improvements that will spruce up the room or more drastic changes that will turn your basement into another living space, here are some ideas to get you started with your basement revamp:

Basement renovation examples

Working at your dining room table can only suffice for so long. By redesigning your basement to make it an open space with sufficient lighting, you can create the optimal work environment for yourself without having to sacrifice more space in other parts of your home.

For someone who has frequent guests or is even looking to provide extra rental space, installing a bathroom in your basement is a highly useful renovation project. Basement bathrooms can greatly improve the functionality of the space as well the value of your home.

If space for overnight guests and larger gatherings is often limited, basements can provide great potential for opening up your home with ease. By adding in some warm wood or carpeting for the flooring and expanding the space for larger pieces of furniture, your basement can become the next coziest spot in your home.

We know how stressful it can be to undertake a home renovation project. That's why we’re here to support you at every project stage, from planning to construction. From facilitating your search for a vetted general contractor to ensuring that your renovation goes smoothly, you can rest assured that your project is in good hands. We’ll be your right-hand person advocating for your vision all the way through so that the final results meet your expectations.

Per square foot, the average cost of a basement renovation is approximately:

Standard: $85

Mid-range: $130

High-end: $215

The price of your renovation will also depend on the scope of the project. Our project managers will help you define your project scope and send you a detailed budget estimate before you meet with general contractors.

Billdr will help you find the right general contractor for your project. All of the general contractors we work with have gone through a rigorous vetting process to ensure high-quality craftsmanship and strong work ethics. Through our network, you’ll be able to choose from qualified and reliable contractors with valid licenses and insurance that covers personal injury and property damage.

Tell us about your project to set up a personalized phone call and home visit to assess your renovation needs. As soon as your detailed project scope and budget estimate are ready, your project will be live on our network of certified general contractors. Depending on your project’s size, you will then receive two-to-three comparable quotes to choose from.

A building permit is required if you plan on modifying how a room is being used (e.g. adding a bathroom, converting a bedroom into a kitchen, adding an extension, etc.) or changing the outside of your property (façade, windows, etc.). To find out if you need to apply for a permit, check with your municipality. You can also read our guides to learn more about building permits in Toronto or building permits in Montreal.

Changes to your project that occur once construction has started are called change orders. Navigating them can be tricky, but that’s why your Billdr project manager is here to help. You can send your change requests to your general contractor in writing, but make sure that your project manager is included in all communications. Before any changes are made, ask what kind of impact these changes will have on your timeline and the costs of your project to avoid unwanted surprises.
