"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."

"I can’t say enough good things about Jake and his construction company. He recently completed an addition on our home, and the entire experience was outstanding from start to finish. Jake was professional, dependable, knowledgeable, and took a lot of pride in his work. He kept us informed throughout the project, paid attention to the details, and made sure everything was done right instead of cutting corners. The quality of the finished addition exceeded our expectations and looks like it was always meant to be part of the house. It’s hard to find a contractor you can truly trust, but Jake is one of them. He showed up, followed through on what he promised, and treated our home with respect. We couldn’t be happier with how everything turned out. I would recommend Jake and his company without hesitation to anyone looking for quality construction work. Five stars all the way — we would absolutely hire him again!"

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 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.

Renovations that add functionality or more comfortable floor space generally add the most value when remodeling your home. Attic or basement finishing can add floor space without altering the home's structure, saving you renovation money while adding valuable space. Smaller improvements, such as installing smart-home components or replacing entry doors and windows, also experience high ROIs. 

Create a checklist, reimagine the space use, set a realistic budget, choose materials and aesthetic details, and get professional support for guidelines and troubleshooting.

For most basement remodels, you’ll want to hire a general contractor. This is for a number of reasons, but the main two are that general contractors have dedicated teams they are comfortable with, and hiring one means you only have to deal with one pro. You may also get a better project quote since they can lump all their work and subcontracting into a single quote.
