"I had spoken to several contractors, Mr. Matthews took the time to explain the entire process of what was needed and why this option would be better than the prior. He was the ONLY contractor to show me his license and make me feel comfortable with all he explained and made sure I understood all that was needed. I appreciate all the time he gave me and the great work his crew did to get my foundation fixed and drainage issue fixed!! Thanks! Sara"

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."

"Service was great from sales, to installation, to post installation support. Very responsive, very professional. It's hard to find in this 'space'--there are a lot of shady people in basement water damage/repair, and this place exceeded expectations. We've had our repair in place for 4+ years, with only 1 small issue on a wall seam crack, and that was fixed within 24 hours of reporting the issue. Stand up place! Thank you for such great service and support."

Basement Waterproofing questions, answered by experts

A moisture or vapor barrier helps separate the warm air inside your home from the cold air outside of it. Without it, your walls could collect condensation, mold, or other damage. Check your local building codes to see if including an interior vapor barrier is necessary for your building project or renovation, especially for rooms that are likely to be humid, like bathrooms.

Foundation problems will likely get worse over time if they aren’t repaired. As foundation problems progress, your home may experience signs of structural damage, water damage, and health and safety risks—all of which will only get more expensive to fix the longer you wait. Repair foundation problems as soon as you’re aware of them to avoid complex and expensive remediation in the future.

If not properly maintained, an underground downspout may damage your home's foundation. A clogged downspout can back up, causing water to pool around the base of your home and seep into the foundation. Regular inspections and maintenance keep your downspout in good working order, preventing damage and protecting your home.

If there is standing liquid on your concrete, remove it before attempting any of the above cleaning methods. For small amounts of water, use rags, a bucket, and a mop. For larger areas of liquid, lay down cat litter or baking soda to soak up the water first. If you have extremely large pools of water sitting on your concrete, break out the wet vac and get to work.

Pooling or standing water in your basement should be cause for alarm and action. This indicates that there is a leak or a drainage issue, and until you repair the root of the problem, the situation will only happen again or grow in severity. It’s important to deal with water damage as soon as it occurs.
