"I was very hesitant to hire a contractor to finish my basement. Now that it is completed, I am very happy I selected John over the many others interviewed. The basement is beautiful and exactly as we had discussed prior to starting the project. He was very flexible with minor changes and completed quality work. I will contact John again should I have any additional home improvement needs. Nice work John!"

"Guy and his team were amazing and professional. Guy was able to recommend solutions to resolve ongoing water problems in the basement, completed the install and finished the basement. It has added significant square footage and value to our home. Additionally, he completely remodeled the kitchen and was able to suggest small but important finishing details the really brought the project together. The kitchen is transformed and is a gathering spot for the whole family. Guy has also helped us out with smaller odds and ends including installing new outlets and breakers, repairing drywall, and smaller paint jobs. I would recommend Guy and his team over and over again!"

Basement Remodel FAQs, answered by experts

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

Egress windows or doors are required in finished basements to meet safety and building codes. If your basement is unfinished and used as a storage space, egress windows are not required, but anything considered a habitable space must have an additional point of egress in addition to the stairs.

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

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.
