"I recently had Mighty Basement and Bath finish my basement and build a new bathroom, and I couldn't be happier with the results. They did a fantastic job, kept the project on schedule, and stayed right within my budget. The final space looks absolutely amazing! Highly recommend Scot and his team for any remodeling needs."

"Andy & his guys with A&M Construction did an amazing job on my bathroom remodel. A complete gut to a personal spa. Installed a 66" wide, deep soaker bathtub! Makes it feel like a spa every time I walk in. In addition replaced the windows & exterior doors. Excellent work, communication, and attention to details, and of course my needs!"

"Larry and his team did a phenomenal job! We couldn't be more happy. They remodeled our basement (framing, drywalled, ceilings, flooring, lighting and painting), They let us know each day what was to be completed and by what time. Such a breath of fresh air to work with contractors that are not only professional, but provide outstanding work. We will definitely hire again for future projects."

Basement Remodel FAQs, 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.

Building a bar in the basement will likely add value to your home, although it’s unlikely that you’ll see a significant return on investment (ROI) unless you plan on using the space for you and your guests. If you think you’ll use the area frequently, though, it’s probably worth the investment, and you should see a bump in value if or when you sell your property.

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.

The average cost to remodel a basement is between $12,100 and $33,400. Depending on the project's complexity, the price can be as low as $3,500 or exceed $50,200. For a simple project like adding a home office, you might spend between $500 and $3,000. However, a more extensive project, such as adding a bathroom, can range from $6,600 to $16,500. The final cost is influenced by factors like the basement's size and condition, the type of remodel, material choices, your location, and accessibility. For an accurate price, it's best to consult with a basement remodeling team.

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.
