"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."

"Chad and Joe at Whitcomb & Holmes were so great to work with!! We couldn’t recommend them highly enough if you’re looking for someone to remodel your space. From our first conversation with them, we knew that we could trust them to get the job done in our exact vision. They helped us to work within our budget and provided valuable insights and recommendations based on their experience. We’re thrilled with how it’s come out and won’t hesitate to use them for future home projects!"

"Timber and Meghan were great to work with. The price for the work was extremely reasonable and Timber was very flexible and creative with solutions. The original plan was to power wash and treat the existing fence and pergola. Timber suggested going over the old fence with a new fence and building a new pergola.The overall cost for these changes was pretty much the materials. We provided Timber with a photo of a pergola that we found on line and he recreated it flawlessly. I cannot praise Timber highly enough. We are thrilled with the new deck. One of our friends is a retired home builder who is never impressed. He had nothing but praise for the quality and craftsmanship of the work. We already have plans to engage Timber for additional projects. PS We had to order a new dishwasher while Timber was here. He installed it for us and took the old one away."

"Ernest recently completed a basement remodel for our home. It went from a dark, uninviting spot to one of our favorite places in the house. The quality of work is fantastic as well as communication from Ernest regarding when and how things will be done. Ernest is currently working on two other projects in our house and we are already lining him up for more wood floor installs, paintings, and bathroom remodels. Highly recommend!"

Basement Remodel FAQs, answered by experts

The cost of finishing a basement is about $18,400 on average. As you can see, the framing portion of this project costs less, because you’re essentially just dealing with laying the foundation for a finished basement. The finishing portion of the project involves a lot more intricate work and design, as well as high-end materials.

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

Yes, it is possible to turn a regular basement into a walkout basement. Doing so involves excavating the land around at least one side of your basement foundation, installing retaining walls to create a permanent below-grade area outside your home, and then cutting into the foundation to install an exterior door that leads out to the new space. This is an expensive and time-consuming project, but it can add a lot of value and utility to your home.

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.

Any bowing in a basement wall indicates a problem that needs to be addressed by a professional. If your basement wall bows more than 1 inch, it's time for an inspection. Generally, a wall can bow up to 30% of its thickness (around 2.5 inches for an 8-inch-thick wall) before it becomes an urgent situation. Bowing of 2 to 4 inches is more straightforward to fix than bowing of more than 4 inches, which will require significant repairs. If the bowing is more than 6 inches, the wall will likely need to be replaced. The sooner you address the problem, the easier and less expensive the repair will be.
