"Joe answered my email via phone within a couple hours and came out to the property that day. I had him give me some ideas on a remodel of a smaller home we are thinking of purchasing. We wanted to know our options before placing an offer. Joe was extremely knowledgeable, professional and full of great insight. He charged $75 to come out and it was worth every penny. If we decide to do buy the home or have any future needs we would definitely hire Joe."

"Serge did much more than flooring; he also installed electrical (lighting/ceiling fan & outlets) , bathroom vanities and enclosed an indoor storage area with custom doors. He is fair and an excellent worker. We especially appreciate his prompt communication. That work was done summer/fall 2022. Heâ s back now (summer 2023) for more home improvements."

"Volcano Builders transformed our dark, underutilized basement into a cozy, functional hangout space with a wet bar. From framing to lighting and flooring, everything was handled professionally. Bar checked in weekly, communicated promptly, and made thoughtful suggestions for built-ins and finishes. The result is a warm, welcoming lower level with smooth walls, quality cabinets, and soft LED lighting?ideal for family nights. They cleaned up each day and finished on schedule. Truly exceeded expectations."

Basement Remodel FAQs, answered by experts

It’s less expensive to finish your basement than it is to build an addition to your home. The average cost to refinish a basement is $32,000 (between $7 and $23 per square foot) while building an addition to your home costs $50,325 ($80 to $210 per square foot). Depending on the size of your basement and other factors, like moving plumbing and electrical, refinishing a basement is a more cost-effective option in most cases.

The cost of finishing a basement is about $18,400 on average. As you can see, the framing portion of this project costs less, because you’re essentially just dealing with laying the foundation for a finished basement. The finishing portion of the project involves a lot more intricate work and design, as well as high-end materials.

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.

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.

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.
