"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."

"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."

"It was a pleasure working with Wendy and Leo. They did an amazing job transforming my old outdated kitchen into a place I can love for years to come. I didnâ t always like the time line, but learned that a beautiful, livable space doesnâ t happen overnight. All I can say is â trust the processâ ! In the end you will be happy you did. Wendy and Leo worked with me to stay within my budget while still using top of the line cabinetry, countertops, flooring and accessories. I interviewed 4 different contractors before making a decision. You should hire JWL contractors. You will not be disappointed."

Basement Remodel FAQs, answered by experts

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

It is generally more affordable to finish a basement than an attic, though it ultimately depends on how you plan to use the space. The average cost to finish a basement ranges from $7 to $23 per square foot, while attic renovation costs $30 to $60 per square foot. However, a simple attic conversion to a storage space will cost significantly less.

Key trends include home gyms, theatre rooms, additional rooms (bedroom/office), and more, with personalized styles reflecting individual preferences.

Yes, most general contractors require an initial down payment, typically between 10% and 25% of the total project cost. This upfront payment helps cover the costs of materials, permits, and subcontractors. The remaining project costs are usually billed after specific project milestones are reached or on set completion dates, as outlined in your contract. Be wary of contractors who require a significant deposit of 50% or more upfront, as this could be a red flag for a scam.
