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.

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.

  • 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.

Job Stories From Alexandria, VA
Basement Peace of Mind in Alexandria, VA

This Alexandria, VA homeowner had plans to finish his basement. Unfortunately, those plans were delayed due to continued water intrusion in the basement. We proposed the installation of our WaterGuard sub-floor drainage system, a 1/3 hp TripleSafe sump pump, a new exterior drainage line complete with IceGuard to prevent clogging, and CleanSpace vapor barrier to permanently fix his water issues. This prevents further damage and allows for peace of mind to finally finish the basement to make it an enjoyable space. 

Work Requests From Alexandria, VA
Vicinity of E Walnut Street in Alexandria
One side of our house is lower than the other, and the basement window wells occasionally have some water spilling over the lip during heavy rains. This isn't normally too much of a problem: we have a sump pump that's connected to the window wells. We're interested in installing some higher window wells on that side though to try to avoid some of the stress on the sump pump during heavy rain events. Would love to get y'all's opinion on what might be possible
Vicinity of Edgehill Court in Alexandria
Hello. I'm interested in someone taking a look at a crack in our foundation. I don't know if describing the crack size or location make a difference before a visit, but I can describe further and/or provide pictures if that helps. Thanks! - Patrick

Vicinity of N Cliff Street in Alexandria
Hello! I have water coming through the cinderblock walls in my basement - looks like the previous waterproofing job has failed after time. I didn't discover it until today but it looks like it's been happening for some time due to the mold and decay. I'd like someone to come take a look, figure out what's going on, and provide an estimate. Thanks!
