Lux Renovations, LLC exclusive provider of the Owens Corning Basement Finishing System, has been serving New England homeowners since 2002. Our dedication to customer experience and satisfaction has won us Owens Corning's top customer service ranking nationally for the last 17 years in a row. Something like that doesn't happen by accident. We are committed to insuring that all of our customers describe their experience with us as "the best contractor experience I ever had". If you are considering a basement finishing project please allow us to show you how Owens Corning has changed the industry with this unique system. A free consultation and design is always available.

"Overall, the finishing of my basement went pretty smooth. The Owens Corning product, drop down ceiling, and flooring are all really sharp. In the beginning everything went fast and smooth with the framing and wall/floor/ceiling install being done within 2 weeks. There were some hiccups with minor imperfections, tv mount in wrong spot, etc. Those were fixed promptly. After that is when I ran into issues with other items in my contract that were not taken care of and the project felt forgot about. Just had some minor electric work, stairs to get carpeted, and didn't receive hanging clips yet. I had to constantly ask about these items and every answer would be "I forgot to ask or send the clips". I eventually got the items completed, but am not happiest that it took almost a month and constant reminding to get these items that should've been scheduled for during the project."

Carpenters cut, measure and shape lumber in useful ways. Working from a master plan, they create wooden structures, piece by piece. Their work involves mastering a wide variety of hand and power tools. Some of the work they do involves cutting wood using chisels, planes, saws and sanders.

"The first picture is our family deck before and the second is after. I could not recommend Norsemen Construction enough! The founder is extremely reliable and reasonable, they are willing to make sure you get what you are looking for and then some. They had also done two door replacements for us, beautiful work. We will be contacting Norsemen in the future!"

Basement Remodel questions, answered by experts

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.

Since DIYing a basement remodel isn't typically advised, there are some ways that you can still save money on this project without putting yourself in danger. Some ways to save money on a basement remodel include:

  • Painting walls yourself versus including in the cost of the remodel 

  • Installing light fixtures yourself

  • Choosing prefabricated fixtures, like cabinets, over custom ones

  • Choosing a budget-friendly flooring option, like laminate or vinyl flooring, and add rugs where necessary

The cost to remodel a basement is between $12,100 and $33,400 for the average homeowner. The price you pay can be as little as $3,500 or as much as $50,200, depending on the size and condition of your basement and the type of remodel you're doing. 

If you're doing a simple project like adding a home office to your basement, you can expect to pay anywhere from $500 to $3,000. However, if you're adding a bathroom, which is an extensive project, you can expect to pay between $6,600 to $16,500.

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.

You technically can paint wires in a basement ceiling, but there are several important safety and code considerations. It's safe to paint non-metallic sheathed cable as long as the labeling remains visible. You can also paint low-voltage wires and conduit and junction boxes to help them blend into your basement. 

However, you should not paint damaged or deteriorated wiring is a fire hazard because it poses a fire hazard. The same goes for painting over high-heat wires that connect to heat-generating appliances or systems. Be sure to avoid painting multiple coats onto any wires, as that traps heat and poses fire risks.
