"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."

"Ed Calabrese and his crew were excellent . Ed was the only one who did a lot of the detail on the front end in terms of his quote and the only change on the back end was an item I asked for which was out of his scope. He had a great crew and made changes as appropriate along the way"

Basement Remodel questions, answered by experts

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.

Some older homes have toilets in the basement to combat sewage backups. This type of toilet, also known as a Pittsburgh potty, acted as a safety valve over the incoming sewer line. If a line backed up, it would back up into the toilet because it was the lowest fixture in the home, keeping it out of sight and away from the finished areas of the house.

Basement toilets were also used by workers with messy jobs, like those who worked in coal mines or steel mills. This way, they could clean up and avoid tracking dirt through their home.

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.

Efficient appliance positioning, optimizing existing plumbing, and sourcing energy-efficient materials reduce financial impact and increase sustainability.

If you don’t have a crawl space but have a partial basement you want to make deeper, you can expect to spend a little less—between $40,000 and $90,000 on average. However, if you’re not adding new finished square footage, you won’t see much in the way of ROI.
