"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 best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

Lifting a house and adding a basement is one way to add usable square footage. Lifting or jacking a house is a complex process, and it can be expensive, not to mention that you won’t be able to live in your house while it’s lifted, due to safety concerns. Lifting a house should only be done by experienced professionals.

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.

Building a bar in the basement will likely add value to your home, although it’s unlikely that you’ll see a significant return on investment (ROI) unless you plan on using the space for you and your guests. If you think you’ll use the area frequently, though, it’s probably worth the investment, and you should see a bump in value if or when you sell your property.

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.
