"The Lux Renovations crew did an excellent job with our basement project. We were able to transform 800 square feet of unfinished space into a rec room with areas for ping pong, exercise and watching TV. We went with the paintable wall panels and were happy with that choice. We also went with the Karndean vinyl flooring in nude Danish Oak finish and are happy with the light hardwood floor look. The crew was very careful with all measurements, and the end result is a nicely finished space with all walls and ceilings and doors perfectly plumb and true. Dave G. was our project manager and was great to work with. James was our on-site supervisor, and he worked long days to keep the project on track and was highly skilled at everything he did."

"The company (Black Dog) was hired to expand the bathroom and part of the basement renovation. The project started in October 2020 and it is still going through May 2021 with an unclear restart date after 2 no shows. It was promised to finish by Christmas. The company used 2 different colors of grout in the same room. They are planning to come back and redo it, waiting for 2 months now. They do not want to spend time on fixes. Leakage around the shower was noted, they promised to contact the subcontractor, but I have not heard from them yet. There are minor things missing, would pay attention to their contract as they may not do things like shelves installation as originally discussed. They seemed professional on initial evaluation and at the beginning, but now I am regretting that I hired them."

FAQs for basement remodeling projects in Amherst, NH

While the terms remodeling, renovating, and finishing are often used interchangeably, there are some differences. Remodeling your basement transforms the space by changing its layout, adding new features, or altering its function. Renovating restores the existing space to like-new condition without major structural changes. Finishing converts an unfinished basement into a livable area with walls, ceilings, and flooring.

A full basement remodel typically takes two to six weeks, depending on the project's complexity and any unforeseen challenges. Factors like design changes, permitting, and material availability can affect the timeline, as well as the availability of the contractors you’re working with. Remember that the bigger the project, the longer it will take to complete.

Remodeling your basement is not just about gaining extra space—it's a savvy investment. You can expect around a 70% return on investment (ROI), comparable to other major home improvements like kitchen or bathroom remodels. Adding functional living space boosts your home's value and appeals to potential buyers. Plus, converting your basement into a rental apartment could provide additional income, increasing your return even more.
