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.

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

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:

  • 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.

Work Requests From Alexandria, VA
S Jordan St in Alexandria
Need an egress window in my basement.
Adrienne Dr in Alexandria
Split level crawl space; water seeping in around water service line penetration. Have it diverted to well/sump pump, but looking for a permanent solution. Signs of water seepage along foundation high side as well.
Mount Vernon Memorial Highway in Alexandria
We have a 4-6" vertical crack in the cinder-block foundation. On wet days, water comes into the foundation. The sump pump ejects the water, but I'd like to keep it from coming in in the first place. Looking potentially at epoxy crack filling solutions.
E Nelson Ave in Alexandria
I have a two-story house with a small crawl space below. In the winter, the first floor of my house is very cold, much colder than the upstairs, especially in one room. If we keep the central heating warm enough to make the first floor comfortable, the second floor quickly becomes too hot. Awhile back, an HVAC specialist suggested that some form of crawl space insulation or barrier might be one way to help take some of the chill off. I would like to explore options that might be cost-effective ways to help maintain comfort in all living spaces.

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 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.
