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."

"Our inspector, Mike Mele, was wonderful. From start to finish, he not only was very professional and polite, but he did an amazing job of telling us our problems (pretty major) without fear mongering us into upsales. He told us our problem, recommended a solution, gave us a very reasonable price to said solution, and then constructed us a payment plan process that won't hurt our pockets and will ease our stress. Thank you so so much! Im freaking amazed and grateful as hell. "

Looking for a professional that will give you an honest price and the best craftsmanship around? Armour Home Improvement is the company for you! Call us today, we look forward to speaking with you (301) 570-8041 or (410) 489-6004! (Please note that we only do complete remodels and not single item projects).

"I selected Armour over other contractors bids for my basement remodel and I am very happy that chose them. During the bidding process they answered all of my questions quickly and thoroughly, their proposal was thorough and clear, and they were happy to discuss my ideas, thoughts and concerns. The crew that did the work was fantastic. Those guys are pros. The scope of work included all new framing and drywall (up to code, unlike before they came in), replacing that damn stucco ceiling with new drywall, upgrading the bathroom and kitchenette, new flooring, new basement door and replacing the ancient basement window, plus upgrades to the interior basement stairs and bathroom exhaust fans. Everything passed inspection and I am a happy customer. I would hire Armour again in a heartbeat. Many thanks to Rob, Christina, Rudolfo and everyone who worked on the project."
