"We had a great experience with the Lux Renovations and Owens Corning team. The whole process was very easy from designing the space, selecting colors, and having a contract manager who organized the entire basement remodel including all the trades and inspections. We were sold on the Owens Corning materials for the basement and that they were engineered specifically for a basement space. Would highly recommend this team for your basement remodel needs."

"I recently hired LionHeart Finish Carpentry for a bathroom remodel, and I honestly couldn?t be happier with the results. The entire process was smooth from start to finish. They were professional, punctual, respectful, and paid close attention to every detail. The quality of the work truly surprised me ? the bathroom came out even better than I expected. Everything looks clean, modern, and very well finished. They communicated well throughout the project and made sure everything was done the right way. It?s hard to find contractors who combine quality, professionalism, and reliability like this. I would definitely hire them again and highly recommend them to anyone looking for remodeling or finish carpentry work."

"Hired David Pierre, his crew and sub-contractors to install a new bathroom, remodel an existing bathroom, convert an attic to living space, install spray insulation, and rewire our 180 year old house in Plymouth, Ma. David impressed me with his professionalism and straight-forward approach, and I was not disappointed. Honest and committed to the end. Construction jobs always seem to take longer than expected, and this was true here, as well, but I think it is due to the nature of the business -- coordinating the schedules of several subs and dealing with unanticipated issues, especially when working on an old house. David juggled it all well. His core carpentry crew, Paul and Derek, were skilled, dedicated and responsive to requests. They kept the ball rolling forward. Good quality work at reasonable prices -- it would have cost me substantially more to use one of the larger home remodeling firms and I probably would get far less top-level attention."

Basement Remodel FAQs, answered by experts

To determine if your basement walls are suitable for finishing, assess their structural integrity and moisture conditions. Look for any signs of damage, such as cracks, bowing, or excessive moisture. Ensure proper drainage and address any underlying issues before proceeding. 

Consult with a professional if you're uncertain about the structural stability or potential risks associated with finishing your basement walls.

Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.

Professional remodelers streamline the process, manage permits, and handle renovations efficiently—significantly mitigating risk while maintaining standards.

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.

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.
