"We are currently happy with the basement waterproofing and remodeling that was completed! There were issues - most minor but we haven't anything to compare as this was the first-time having contractors complete basement work for us; and our home is almost 100 years old. They were flexible given unexpected issues that came about with the basement. The water proofing was done first and they did a great job. They were happy to review and resolve any remaining questions/concerns and/or issues. Jorge in the service dept. is professional, punctual and is a great representative and asset for this company."

"Martin quickly responded to phone calls. His employee was very prompt, pleasant, and a hard worker. The floor looks wonderful! I would highly recommend them. This is the second time we have used them. 7 years ago we used them for a total basement renovation including bathroom installation. We were very pleased with the quality of that work as well."

"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."

"I was very hesitant to hire a contractor to finish my basement. Now that it is completed, I am very happy I selected John over the many others interviewed. The basement is beautiful and exactly as we had discussed prior to starting the project. He was very flexible with minor changes and completed quality work. I will contact John again should I have any additional home improvement needs. Nice work John!"

"Guy and his team were amazing and professional. Guy was able to recommend solutions to resolve ongoing water problems in the basement, completed the install and finished the basement. It has added significant square footage and value to our home. Additionally, he completely remodeled the kitchen and was able to suggest small but important finishing details the really brought the project together. The kitchen is transformed and is a gathering spot for the whole family. Guy has also helped us out with smaller odds and ends including installing new outlets and breakers, repairing drywall, and smaller paint jobs. I would recommend Guy and his team over and over again!"

Basement Remodel questions, answered by experts

Assess your foundation type and ceiling height before starting basement remodeling. Mid-century homes with poured concrete foundations and ceilings over seven feet represent the best candidates. Check local flood maps to ensure your Wilmington property avoids strict flood zone restrictions. Verify your basement has a functional sump pit and no history of water intrusion. Finally, complete a DE radon test and confirm local zoning rules.

Helpful?

Hidden expenses during basement remodeling stem from the age of Wilmington housing stock. Upgrading knob-and-tube wiring and abating asbestos or lead paint require professional attention. Anticipate expenses for radon mitigation systems, as DE is a high-risk zone. Upgrading your plumbing to handle combined sewer systems and fixing deteriorated stone foundations or active water seepage add mandatory steps to your project.

Helpful?

For basement remodeling in Wilmington, keep a reliable humidity monitor on hand to manage the persistent Mid-Atlantic moisture. Maintain tools to clear clay sediment from your window well drains and sump pit inlets. Install a battery backup for your sump pump to handle power outages during storms. Additionally, keep radon test kits and crack gauges available to monitor foundation shifts during DE freeze-thaw cycles.

Helpful?

Address active water intrusion, elevated radon levels, and failing sump pumps immediately to protect your home. Delaying foundation repairs allows DE freeze-thaw cycles to worsen existing cracks. Conversely, defer cosmetic basement remodeling and bathroom additions if your space remains dry and safe. Submit your permits in the winter to avoid the busy spring season and ensure your Wilmington project stays on schedule.

Helpful?

When planning basement remodeling in Wilmington, account for the clay-heavy soils and proximity to local rivers that create flood-prone zones. Older homes in areas like Trolley Square feature stone foundations requiring specialized approaches. Address older infrastructure, such as knob-and-tube wiring and combined sewer systems, early in the process. Finally, test for radon before starting, as DE falls into the highest potential zone for this gas.
