Groundworks offers dependable foundation and crawl space repair solutions, basement waterproofing, and concrete lifting for New Jersey residents. We take pride in restoring the value and safety of homes in our local community.

"Working with DJ from Groundworks (Select Basement) has been an outstanding experience. After struggling with various contractors who either failed to resolve our water issues or were unprofessional, DJ and his team truly stood out. DJ was incredibly helpful, patient, and responsive throughout the entire process. Our home is a ranch with 225 linear feet around the perimeter, and while other contractors insisted on installing a French drain for the entire length, DJ recommended a more targeted approach. He proposed installing the French drain for just 80 linear feet, focusing only on the areas where water intrusion was likely. His thorough explanations and prompt responses to all our questions were greatly appreciated. The workers arrived on time, maintained a clean work environment, and completed the job as promised. If we could give 10 stars, we would! Groundworks is a highly professional and honest company that didn't try to inflate the scope of work to charge us more. We wholeheartedly recommend them."

"Premier Basement Waterproofing is amazing! My 100 year old basement was musty & damp. I would get inches of water after a rainstorm. Nelson installed a French drain & sump pump which immediately got rid of the water seeping in. He also put up a vapor barrier which has kept my basement dry & no longer musty. My basement is completely water free and it’s been at least 15 months. It’s an amazing difference! I wish the ceiling was higher as it would be a great living space. I would recommend you use Nelson and his team if you want your basement problems to go away! Notice the before & after pictures: "
