"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."

Drain Pipe Installation questions, answered by experts

You can remove air from your shower pipes in a few simple steps. Turn off the water at the main water supply and open all the faucets in your home, starting with those closest to the water supply and working away from those. Let the faucets run dry, then flush all the toilets in your home until there is no more water in them. From there, turn the water supply back on and let it flow for 10 to 15 minutes until the sputtering stops. To finish, turn off your faucets and flush your toilets in the reverse order.

Yes, insulating your cold water pipes is a great way to prevent condensation. When warm, humid air meets cold pipes, condensation forms, which can drip and cause moisture issues in your home. Pipe insulation acts as a barrier between the warm air and the cold pipes, keeping condensation at bay and helping you avoid potential problems like mold or structural damage.

To measure pipe size, you can use a ruler, a soft tape measure, or a caliper. You can find a special pipe caliper that has iron or copper pipe sizes already marked. Rulers work if the end of the pipe is exposed. If your pipe is still attached to the plumbing, you’ll need to go for a soft tape measure or caliper.

The size of the pipe you use for your shower depends on the part of the shower you’re installing. Shower drainpipes have a 2-inch diameter, and the water supply lines (both hot and cold) have a ½-inch diameter. You may want to slightly increase the size of the vertical pipe if you have dual showerheads. Check the local building code prior to installation for guidance.

Yes, professional installations typically include safe gas and plumbing connections.
