"We hired MH Construction for a kitchen renovation, and we are thrilled with their work! Mike and his team were excellent from start to finish. Mike kept in regular contact with us throughout the process, answering our questions and working out the design. He and his team were amazingly efficient, often getting more completed each day than we’d anticipated, and they were polite, professional, and always kept the work area clean and safe. They also went the extra mile and conscientiously fixed unexpected issues they found, including several smaller electrical and plumbing glitches. Best of all, we couldn’t be happier with the end product: our kitchen is beautiful and more functional than ever.

Basement Remodel questions, answered by experts

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.

It may not come as a surprise that the kitchen is the most expensive room in the house to renovate. This is due to the expensive appliances like the range, hood, and fridge, but also because the bones of the room—like electrical and plumbing—are expensive to move or replace. While there are ways to renovate a kitchen on a budget, it will always carry a hefty price tag, even if you cut some corners.

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.

Yes, adding a walkout basement will usually bump up your property value. Most homeowners prefer walk out basements because the exposed wall that’s level with the ground provides more utility via a ground-level exterior entrance, and they can fit full windows, which adds natural light and ventilation to the basement area. The only exception might be in areas prone to tornadoes, as walkout basements aren’t as safe as regular basements during a tornado, particularly if they include large windows or glass sliding doors.

Although homeowners often use the terms basement remodeling and basement finishing interchangeably, they are quite different terms. 

Finishing a basement is the process of taking a basement space that is not habitable and adding elements to make it usable. This includes adding plumbing, flooring, and insulation.

Remodeling a basement means taking an already existing finished basement and changing it, often by adding or removing walls, adding plumbing, or changing the existing flooring.
