"We hired McCormick Home Builders to remodel our living room, and we are beyond pleased with the result. The team was professional, worked efficiently, and Aris design ideas made a huge difference. The room feels so much brighter and more spacious. This was the best decision we made for our home, and we were already planning our next remodel with them."

"We hired Nextgen Home Repair to remodel our already converted garage back house so we could turn it into a comfortable living space for a family member. Before the remodel, it technically functioned as a space, but it didn’t really feel livable or welcoming but now it definitely feels like a home!! They fully repaired and updated both the inside and outside of the garage. The interior feels completely refreshed and everything looks clean and brand new. On the outside, the repairs and updates made a huge difference too so it finally looks like it belongs with the rest of the main house. The team was easy to work with, communicated clearly, and made sure everything was done right. You can tell they care about the quality of their work. We’re really happy we chose Nextgen Home Repair."

Basement Remodel FAQs, answered by experts

Yes, it is possible to turn a regular basement into a walkout basement. Doing so involves excavating the land around at least one side of your basement foundation, installing retaining walls to create a permanent below-grade area outside your home, and then cutting into the foundation to install an exterior door that leads out to the new space. This is an expensive and time-consuming project, but it can add a lot of value and utility to your home.

Yes, barndominiums can have basements. Barndominiums are typically built over concrete slabs, so barndo basements are not very common. However, it is possible to include a basement in a barndominium blueprint as long as you’re building completely from scratch. Barndos can have the same types of basements as traditional homes, including full or walk-out basements.

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.

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

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.
