"I was skeptical at first to hire someone that wasn't licensed but Ed does have Liability Insurance so that made me much more comfortable. Once they started the project I was so impressed with what Ed knew about the work he was hired to do. He gave suggestions when needed and even went and picked up and picked out various appliances and fixtures which were worked out well. It sure made my job a lot easier. Ed's background makes him great for owning his own company and becoming a success. I highly recommend Ed."

"Nextgen Home Repair did our bathroom remodel and they did such a great job. Honestly what I liked most was how easy they made everything. Remodeling can be stressful, but they kept us updated and explained things clearly along the way. The attention to detail really stood out, the tile work looks amazing and everything feels solid and well done. They were respectful of our home and made sure things were cleaned up at the end of each day. The finished bathroom looks modern and exactly like we envisioned it. I would absolutely recommend them."

Basement Remodel FAQs, answered by experts

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.

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.

Framing a basement takes three to five days, on average, when completed by a professional, though it may take longer for a larger space. Keep in mind this doesn’t include the time to complete the design, obtain permits, and install the drywall on the framing. On average, fully finishing a basement takes an average of 45 days.

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.

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.
