"We love our basement remodel. Peter, Alex and his team were here when they said theyâ d be here, completed the job as described, and kept us updated along the way. The basement now looks and feels clean and bright. The additional space doesnâ t feel like a basement at all and is enjoyed by the whole family. We highly recommend Lux Renovations."

"The kitchen was completed gutted and rebuilt within 3 weeks. Matt worked with us on every aspect of the remodel and addressed everything we had on our wish list. On all the projects Matt and his people were here every day until the work was completed to our satisfaction. When they left each day the work site was spotless. We have been happy to recommend MNB Renovations to our friends and family and plan on having Matt back when we are ready for our next project(s)."

"Steve and Mike were so professional and absolutely came through for our basement remodel/ construction. They were very flexible, detail oriented, went above and beyond to make us happy and most of all reliable. We made a few changes on the go, and Mike and Steve were so accommodating to that! I cannot say enough wonderful things about their work! We look forward to working with them in the future for other home projects."

"Dream come true on my two bathrooms. From beachouse style in one to rustic cabin style in the other, I couldn't be more happier! After my flooring was about to fall through, finding mold in the drywall, and also finding holes in the septic vent pipe that went up through behind the drywall I was glad we did the renovation when we did and were able to resolve all the issues."

Basement Remodel FAQs, answered by experts

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.

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.

Yes, barndominiums can have basements. Barndominiums are typically built over concrete slabs, so barndo basements are not very common. However, it is possible to include a basement in a barndominium blueprint as long as you’re building completely from scratch. Barndos can have the same types of basements as traditional homes, including full or walk-out basements.

Unless you have extensive experience in construction work, remodeling a basement is best left to a professional. There are several tasks associated with this project that require exact precision, including:

  • Replacing insulation 

  • Replacing carpet or other flooring 

  • Adding heating and cooling

  • Adjusting or adding walls and doors

  • Altering or adding plumbing elements

If any of these elements is done incorrectly, it could severely impact the quality of your basement remodel and be dangerous. Changing a basement often comes with code safety requirements, like egress windows and proper ventilation. Therefore, leaving it up to a professional is often the best decision.

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.
