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 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:

  • 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.

Work Requests From Alexandria, VA
Grist Mill Woods CT in Alexandria
Due to crack in basement wall, water comes in when there is rain.
Hunter Murphy Circle in Alexandria
Noticing cracks along wall where it meets the ceiling on top floor of three floor townhome. Only in one bedroom so far. Paint starting to chip on ceiling where crack formed. Also, starting see horizontal cracks along wall of second floor staircase leading to top floor. Cracks have widened since moving into home back in March 2017.
Elmwood Drive in Alexandria
We have some structural issues in our crawl space. A contractor repaired a block foundation wall in August and the wall failed which has caused additional damage.
Laurel Road in Alexandria
Vented crawlspace of a split level home without any insulation of any form. This is affecting the temperature at the lower level of the house, as well as the middle entry level stairs. Interested in addressing this issue with encapsulation if that is the best way to proceed. That way the crawlspace can be used for storage.
Truman Ave in Alexandria
Bouncy floor and would like to isolate 1 pillar would like an engineer to chek and estimate.to fix
Mack Street in Alexandria
I think I may have a hairline crack (or two) in our basement. We've had some past leaking issues -- one recent -- and I've removed the carpet tack and padding and in one case, the base. We need to have 2 sections of wall removed to assess whether there is mold and any issues and to have those remediated.
N Columbus Street in Alexandria
Water seeping into the basement. Mold starting to grow.
Chestnut Pl in Alexandria
Crawl space needs to be waterproofed. Needs mold remediation for slight mold (not too bad) and we are interested in the de-humidifier as well.
