JES Foundation Repair (JES), A Groundworks Company, specializes in helping homeowners with their foundation repair, basement waterproofing, crawl space encapsulation, and concrete needs. Our top priority is providing high-quality home repair solutions and personalized service across Virginia and Maryland. With fully trained technicians, industry-leading products, and nationally backed warranties, JES is here to restore your foundation or crawlspace.

"JES left my home in worse shape and will not return my calls to come repair the damage left. I reached out to them to install a joist support system under my kitchen so that I can renovate this year. There were floor joists under the back door that had been cut during a renovation about 30 years ago. JES installed a jack system but then left my foundation under the door where you can literally see daylight from the basement. I brought this up to the crew before they left late Friday night (they worked long hours just to ?finish? without even asking me if it was okay to trap me at home that late), and the lead just shrugged at me. Shortly after they left, it rained, and sure enough, water poured into my electrical room and all over the freshly poured concrete. I called Friday night, sent an email and text with videos, and called today 3 times. Each time the ?production manager? is ?busy.? Before this, they were perfectly capable of blowing up my phone to see if I could schedule sooner."

"After having a horrible experience with Andre and filing a complaint with the GM for the area, results still remain to be seen. So professionalism is non-existent and follow-thru still hasn't happened. The word of the GM, contractor supv as well as the actual contractors/engineers are garbage. Character by way of integrity and keeping their word is definitely not available with this company. Don't believe anything they say."
