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.

We are seeing signs of foundation issues. Cracks in the foundation exterior, separation from moldings and drywall, appearance of cracks in drywall. Seeking estimates/solutions for repair.
Vicinity of Woodland Terrace in Alexandria
You all did my waterproofing in my last house and did a great job. About a year ago, we moved into a new (old) house and have noticed some troubling signs of foundation problems - cracks above door frames, sloped floors, etc. Hoping you can come take a look and let us know what might be necessary. Thanks.
Vicinity of Cornell Drive in Alexandria
We have a growing number of drywall cracks, some significant. We've had one evaluation of our foundation and I would like another evaluation and an estimate for TBD foundation repairs. Thank you.

Cracks on ceiling
Vicinity of Guthrie Ave. in Alexandria
By the end of our very wet summer and fall, a relatively small but persistent leak developed somewhere around the frame of the door of our walkout basement. I seem to have stopped it - at least temporarily - with "Great Stuff" foam, but I am looking for advice on a permanent solution to ensure that it doesn't leak again and I'm getting proper drainage away from my house. Please feel free to reach me on my phone number listed above, but I may not be able to answer before 4:30 pm. Thank you!
