Basement Waterproofing & Leak Repair in Alexandria

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. If poor surface water drainage, a clogged French drain, or a broken sump pump are to blame, we can install a new waterproofing system to protect your home and keep your basement dry.

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
  • ENERGY STAR-rated SaniDry dehumidifier - No water buckets to empty and has a built-in air filter to trap mold spores and dust

If you need basement waterproofing, contact us today! We'll design a custom waterproofing system for your home and provide you with a free estimate on the cost of the products and installation.

Foundation & Structural Repair in Alexandria

Wall Anchor System Installed

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 Alexandria, 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
  • Sticking doors and windows
  • 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.

Vicinity of E Maple Dr in Alexandria
Hi, I would like to get a quote for an interior French drain, speed drain, sump pump and mold remediation. Thanks
Vicinity of Crestwood Drive in Alexandria
We had major flooding in our basement in July 2018. After doing what we were told was a fix for the issue we again had flooding during the last major storm about 2 weeks ago, albeit only a few gallons instead of the 4-6 inches previously. We now think we need to retrofit with french drains, which were not installed earlier; only a sump pump was put in. We would like to do the work in the fall as we have some major family events right into early October.

Vicinity of TORON Court in Alexandria
Bowing basement walls.
Vicinity of Adams Avenue in Alexandria
We live in an older home in the Del Ray area of Alexandria and up until last summer we had no or very little dampness/water in our basement. We were moving down the path of having our basement remodeled when last summer during one of the heavier rain falls, we had water dripping down a wall that has never seen water before. So we put our plans on hold knowing we would have to get our basement assessed and probably water proofed. Would love to have someone come out and take a look, let us know how much and ideally move forward.
