Basement Waterproofing & Leak Repair in Herndon

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.

We only install products that we know work, this includes:

  • Multi-pump, cast-iron, submersible sump pump systems with built-in high water level alarm
  • Battery backup pumps for continuous operation and protection in power outages
  • Clog-resistant interior drainage channel - Collects water from walls and drains it away before it reaches the floor

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. 

We offer a full range of foundation repair solutions in Herndon, including patented helical piers, push piers, wall anchors and crawl space jacks. We can handle any foundation problem. Normal settlement can cause foundation cracks, but they could also mean a serious structural problem.

Common signs of foundation problems are:

  • Sagging floors and floor cracks
  • Wall cracks
  • Bowing walls

  • Tilting chimneys

We never recommend a solution that you don't need. Our goal is to educate you on all the options and let you choose the best solution for your needs and budget.

There is a L-shaped retaining wall around an exterior staircase that leads down to a walk out basement door. The walls (I think cinderblock) are missing pieces and somewhat crumbling. I'm fixing up this rental property to prepare for listing, so need to address this issue.

Vicinity of Heritage Farm Ln in Herndon
Getting a "moist basement after rains. Seeing discoloration of cement floor, slightly wet carpet, and some clay/dirt in corners of foundation. Most likely due to poor drainage and "not awesome" gutter/gutter extenders". Also have a basement sump pump that... needs help. Would like a pro to come out and give an opinion. Lee

We had bought our house about a year ago and there are a couple of spots on the main floor where the floor is sloped inward toward the inner walls. We wanted to make sure that the house just settled that way and there are no overall foundational issues.

We need covers and walls to be built for our basement windows.
Vicinity of Cross Creek Lane in Herndon
We have a finished basement with a sump pump in the corner of the house. The previous owner informed us of a french drain on the inside and some drains on the outside. When there is alot of rain (more than an inch) in a 24 hour period, or heavy rains in a short period of time (few hours), there is water seepage near the basement door. We are unsure how this water is entering and would like it evaluated, as well as the sump pump system. Thank You.
Vicinity of Lazy Glen Lane in Herndon
I would like to replace an existing sump pump in my home with one with a battery backup system. I'm interested in a pump system with battery backup or a pump with a secondary pump that is battery backup. I also have a hairline crack about a foot and a half long running from the corner of a basement window that Id like to have assessed for options to seal. *My preferred method of communication is email*
