"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."

"Sean and his crew provided exceptional work. The company is professional and offers fair pricing. They remodeled my mother's bathroom, taking it from the 1970s to a sleek modern bathroom. Sean is meticulous and went over and above to make sure the job was just what my mother wanted. I would highly recommend this company."

"Every step of the way was above expectations. Scheduling was easy, I was notified of ETA, and Al, our technician, was prompt and thorough. We needed our gas fireplace cleaned, and the job was done thoroughly, carefully, and efficiently. Our 25+ year old fireplace now functions perfectly and looks amazing. Can’t beat the price. 10/10 recommend."

"The professionalism and quality was superb. From the very first consult to the last day the owners were available to answer any questions. They walked thru the process from step one. Wendy even assisted with design. Staff always cleaned up everyday and they even became friends with my two dogs. You hear about nightmare remodels but mine was wonderful and it was a large job. Can’t wait for them to do my next project."

"Full bathroom remodel. Lou from LMA Design was great to work with. I appreciated that he always wanted things done the right way. The work was finished on schedule and on budget and I was kept aware of the jobs progression throughout. Once completed, all debris was removed and the entire bathroom was cleaned. I would definitely recommend."

Basement Remodel FAQs, answered by experts

Finishing a basement can provide a great return on investment, by increasing the market price of your home when you want to sell. Beyond that, there are many reasons to finish your basement. Doing so expands the usable square footage of your home, so you can enjoy it more, even as your family grows. Renovating your basement costs less in terms of time, energy, and money than having to search for and buy a new home.

In addition to overseeing new home builds, construction managers work on large renovations and major remodels. For example, they may work with designers and oversee the construction of a finished basement, kitchen renovation, or a home addition. They may also oversee large-scale remodels, such as the update of a historic home. Construction managers step into small projects for more specific assistance, such as building budgets and compiling the team.

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.

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.

Envision the type of bar experience you'd like to create for your guests. For example:

  • Does your basement have enough finished space for bar stools or seating?

  • What type of additional lighting would set the tone for the room?

  • Are there basement windows or an HVAC system?

  • Do you need new plumbing in your basement for a proper wet bar?

  • Could you be happy with a built-in wall cabinet bar rather than a full-scale wet bar?
