If you have leaky cracks in your basement walls or floor, or you have a basement that floods, we have a solution. Our trained technicians provide you with a comprehensive analysis of what's causing your basement water problem, and the proper solution to solve it once and for all.

Wall anchors hold back bowing walls to keep your home stable.

If you have cracks in your foundation, basement walls that are bowing or any other sign that something's not right, let one of our foundation specialists take a look - you'll be glad you did. The sooner you take care of your foundation problem, the less money it will cost you in future repairs.

Hi, Just need to check and inspect an uneven part of our living room and find out how serious it is and get a quote if it needs to be fixed. Thanks

Hello. I am reaching out to schedule an appointment for foundation inspection. We found some water in the basement after several times of heavy rain in spring this year. After that, the floor became a little uneven and there were some dead bugs found in the basement every week. We're looking for some experts diagnosing any problem with the foundation.

Have a cracked wall in our basement. Water gets in when it rains. Need a quote for a fix.
Project Location: Herndon, VA
Cracks in the poured concrete foundation, especially evident in the garage area. The concrete is also damp in some areas and there is spalling in some areas both inside and outside. Back in November 2015 when we bought this house, the seller provided a structural engineering report that disclosed the cracks. At that time, I spoke with the engineering firm who wrote the report and they recommended epoxy injection to repair and stabilize the cracks and seal out water. Unfortunately, the handyman hired by the seller to take care of punch list items before closing just slapped some caulk on the cracks. Finances kept us from addressing the problem at that time. But it appears to have gotten worse since then and we need a proper repair.

Water comes in my basement and need French drains.
Project Location: Herndon, VA
Townhouse with basement water problems. Some flooding which I believe is from neighbors gutter/drainage, has created mold and moisture issues in the basement. There is an existing sump that needs to be better routed and covered. The house is currently rented, so scheduling will have to be coordinated.
Project Location: Herndon, VA
I have an unfinished, underground basement with a concrete stairwell that leads down to it from the outside. There is a hole and cracks in that stairwell which are resulting in the dirt underneath it running down into the stairwell when it rains and clogging the drain pipe that leads to the sump pump. This results in my basement flooding through the door. I need to have those cracks and hole sealed or the foundation around that stairwell repaired
