"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."

"We recently hired Bonus Home Remodeling to remodel our unfinished basement. Rob and his team were outstanding to work with from the onset of the project. They worked with us to make final design decisions, and throughout the entire project they had a large white board set up in the basement outlining a timeline of the projects so we always knew what was coming up next. They arrived at the same time everyday and left at the same time everyday which made it easy to live through such a big project taking place in your home. Rob and his team made everything convenient and easy for us. Any issues or questions that came up were addressed immediately and always ensured that we were happy before moving forward. The finished project is exactly what we were hoping for! It is gorgeous and the quality of the work is excellent."

"During the initial quote process Tom was very knowledgeable and put together a great plan for basement remodeling. My basement was transformed from the style of 50's to a modern basement that I can enjoy with my family. The staff was friendly and worked diligently 6 days a week without interrupting to my day. I received updates through the project from Tom on the progress. The company provided completive rates and this was the best money spent. I would highly recommend this company to anyone looking for quality work, your will not be disappointed."

"Carmello is great. After a flood ruined my basement these guys completely repaired and renovated the space including new french drains, vinyl sheeting behind the drywall, dry locked the window wells and caulked all necessary gaps. Not cheap but they knew exactly what they were doing and since our area has had several storms w record rainfall and my basement has been bone dry. Would use them again in a heartbeat. Highly recommend."

Customers say: Quality work

"John performed a major renovation on our house recently, remodeling the entire first floor, including kitchen, bathroom, closets and a patio as well. He met with us frequently to update progress and include us in the process. He always answered phone calls and texts. He and his crew arrived on time each and everyday. They contained the mess and kept the work site neat and clean. His crew was trustworthy and did high quality work. Highly recommend John and his staff!"

"After a mold remediation project left our formerly finished basement looking like a disaster area, we gave Dave the job of rebuilding it. He replaced the framing, insulation, drywall, drop ceiling, and associated trim and molding. He also corrected some structural problems that were uncovered at the same time, and rebuilt the handrails and banisters on the staircase. All in all, it was a great job and completed in a timely manner. Highly recommended."

"100% recommend these guys. Aaron was very professional and provided fair pricing. Really appreciated that they were straight forward in their estimates and timing. We got our wallpaper removed and walls painted in one of our bedrooms. Wallpaper removal is super tedious and they did a phenomenal job. Even did a couple extra things without being asked, which we really liked! We were very happy with the quality of work, so much so, that we asked them to do another job for us - repairing our shed in the backyard. Once again, they delivered great work in a very timely manner. Will definitely plan on using this company again in the future for other home improvement jobs!"

Basement Remodel questions, answered by experts

When choosing materials for finishing basement walls, consider factors such as moisture resistance, durability, and fire resistance. Opt for materials specifically designed for basement environments, like moisture-resistant drywall or cement board. Insulation with vapor barriers can help regulate temperature and prevent condensation. Consider using mold-resistant paints or coatings. 

Research and consult with experts to select materials that are suitable for your specific basement conditions and intended use. Prioritize quality and compatibility to achieve long-lasting and aesthetically pleasing results.

Joists and beams are both part of the flooring system above your basement, with the beams spanning the length of your home and getting support from vertical posts underneath, and joists usually spanning half the width of your home with no support posts underneath. The floor joists provide even support to the subflooring and flooring above, and they distribute that load to the beams. The beams then distribute that load down through the support posts to the foundation.

Yes, you can add a door to your basement—it might even be required, depending on building codes in your area and whether or not you’re using the basement as a bedroom. A basement contractor can give you some advice on installation and help you add a door to your basement.

Yes, in most cases, finishing a basement is worth the cost. The project adds valuable, usable square footage to your home and typically provides a return on investment (ROI) of 70% to 75%. For example, an average basement refinishing project costing $32,000 could add between $22,400 and $24,000 to your property's value. The final value added depends on factors like your location, the quality of materials and workmanship, and the features you include, such as a living space, bedroom, or bathroom. To be officially counted in your home's total square footage, the finished space must comply with all local building codes, including requirements for points of egress. However, in areas prone to flooding, a finished basement might be seen as a liability by potential buyers and could potentially decrease your home's value.

Create a checklist, reimagine the space use, set a realistic budget, choose materials and aesthetic details, and get professional support for guidelines and troubleshooting.
