"While we have not done the project the team was helpful with getting things sorted out until we are ready to pull the trigger. Mike Walsh was particularly helpful and responsive. When we do the basement we will reach out to Dewar again to actually perform the work."

"I had a great experience working with Guillermo, the owner of D&V Remodelling, for remodelling the bathroom in my condo. He was very knowledgeable and gave me great advice, recommendations, and feedback on the project. When we had unexpected plumbing problems he worked with me to sort it out and still managed to finish the project just one day longer than the estimated timeframe for the project. I would happily work with him again on future projects."

"I love my basement now! They removed all of the asbestos flooring, adhesive etc. and installed my new floor in 2 days. The employees were very respectful and worked efficiently. They had said 3 days but they hustled and did it in 2."

"A&N have been wonderful! They did a great job on the bathroom remodel I needed done on a typical cramped 1950s style bathroom to make room for my mother with her walker. They were able to create so much more space and put in a beautiful walk in shower that works perfectly!"

Basement Remodel questions, answered by experts

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

Making a window in a basement larger costs an average of $4,200. You’ll need to pay an average of $550 to have a structural engineer plan the project, $500 to $1,500 for the installation labor, and an average of $2,200 for the excavation and window well installation. The remainder will go toward pulling permits, installing trim, and repairing drywall on the interior.

Renovation enhances functionality, increases home value, and can add new space for personal or family needs. It typically modernizes older unfinished basements for new uses.

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.

Yes, in most cases, finishing a basement is worth the cost. The project adds valuable, usable square footage to your home and typically provides a return on investment (ROI) of 70% to 75%. For example, an average basement refinishing project costing $32,000 could add between $22,400 and $24,000 to your property's value. The final value added depends on factors like your location, the quality of materials and workmanship, and the features you include, such as a living space, bedroom, or bathroom. To be officially counted in your home's total square footage, the finished space must comply with all local building codes, including requirements for points of egress. However, in areas prone to flooding, a finished basement might be seen as a liability by potential buyers and could potentially decrease your home's value.
