"Matrix completed my basement and we are very pleased with the outcome! The Matrix team were all very personable and professional. Suzanna was always positive and quick with a resolution to any questions or concerns. David and Ron provided professional insight and were on site weekly to manage the trades that were working daily. The supplies were delivered promptly and put in the garage and each trade cleaned up daily before leaving. Mike W. & Brian K. were a pleasure to work with, always early and their excellent workmanship clearly shows. I would highly recommend Matrix for your basement or garage project."

"Joe Timm did an extensive remodel of our 1965 ranch fixer-upper, that included kitchen, 2 baths, great room, 1 bedroom, and den. He was professional and thorough. His price quotes were on-target and reasonable. He was reliable: he called and visited when he said he would. We'll use him again for our unfinished basement. We highly recommend Joe and his work."

"258 Renovations was great to work with. We needed a bathroom added to our basement, but didn't have walls, plumbing, or anything. The crew worked quickly and Mitch made sure to pull all the proper permits. Further, if there was any sort of issue, Mitch made sure to correct it immediately. 258 Renovations was great to work with and I would hire them again."

"It went very well. The new ceiling looks great. When I met with Tom I said I wanted it to be bright as the lights that were in the old ceiling were very small and dim. And as promised, it is very bright down there! I would definitely use this business again. Very professional, cleaned everything up and looks so much better than before."

Basement Remodel FAQs, answered by experts

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

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.

Common mistakes when finishing basement walls include neglecting proper insulation, insufficient moisture management, and poor ventilation. Not addressing these issues can lead to mold growth, water damage, and discomfort. Additionally, inadequate planning, improper framing, and rushing the project can result in subpar outcomes. 

It's essential to follow best practices, seek professional guidance if needed, and prioritize thoroughness and attention to detail.

Key trends include home gyms, theatre rooms, additional rooms (bedroom/office), and more, with personalized styles reflecting individual preferences.

Costs are guided by renovation scope, materials chosen, project duration, structural needs, and labor. Prioritizing tasks prevents unforeseen expenses.
