"Our kitchen remodel with McCormick Home Builders went beyond our expectations. Leoni and her team took the time to understand exactly what we wanted. The open layout design changed the way we use the space, and it’s been perfect for family gatherings. They were prompt, courteous, and genuinely invested in making sure we were happy. Really impressed!"

"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

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.

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.

Yes, you can add a kitchenette to a basement. However, you’ll have to consider the costs associated with basement kitchenettes. If you’re starting from scratch in an unfinished basement, you’ll need to account for brand-new plumbing, electrical, flooring, and more in addition to the cost of the kitchenette. If you’re putting a kitchenette in an already finished basement equipped with plumbing and electrical, you’ll save considerable money.

Rebar is an essential part of reinforcing a basement floor, as not having it can impact its structural integrity. It helps absorb the tension factors that contribute to cracks in your floor and strengthens its load-bearing capabilities by evenly distributing the weight. Not including rebar could lead to an unstable floor, so don’t skip it!

Finishing a basement can provide a great return on investment, by increasing the market price of your home when you want to sell. Beyond that, there are many reasons to finish your basement. Doing so expands the usable square footage of your home, so you can enjoy it more, even as your family grows. Renovating your basement costs less in terms of time, energy, and money than having to search for and buy a new home.
