"The kitchen was completed gutted and rebuilt within 3 weeks. Matt worked with us on every aspect of the remodel and addressed everything we had on our wish list. On all the projects Matt and his people were here every day until the work was completed to our satisfaction. When they left each day the work site was spotless. We have been happy to recommend MNB Renovations to our friends and family and plan on having Matt back when we are ready for our next project(s)."

"We hired Mitch and Bob to finish our basement. They gave us a good and through estimate. Mitch made a couple visits prior to starting the job to make sure we were comfortable with the design, layout and timeline and was very open to suggestions. What is great is that they only take up one job at a time and are committed to it. They were on a consistent schedule. The quality of the job is excellent and everything was very collaborative. Would definitely hire them again if needed and recommend to others. They also took care of many smaller requests we had during the time they finished our basement. They were professional and reasonably priced for the excellent quality of work they did and extremely reliable. Thanks Mitch and Bob!"

Basement Remodel FAQs, answered by experts

Walkout basements are not generally included in a home’s square footage, although they may be if they meet certain conditions that depend on local regulations. A finished walkout basement used as a living space may be counted toward square footage in some locations as long as all codes for livable space are met.

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.

It is generally more affordable to finish a basement than an attic, though it ultimately depends on how you plan to use the space. The average cost to finish a basement ranges from $7 to $23 per square foot, while attic renovation costs $30 to $60 per square foot. However, a simple attic conversion to a storage space will cost significantly less.

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.

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.
