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.

Water leaking through my basement. Need to get an estimate for repair.

Interested in flood proofing my house if that is possible. We have had 5 flood in the last 3 years, first 4 through the toilet the last one through the walls of the basement. We have had one company come out and assess what it would take to improve and protect ourselves, and am interested in a second opinion. Do you provide that service? If so, when is the soonest you would be available to come?

Water is coming into the basement from an exterior wall. Had a company out and they opened up the wall and removed the wet carpet and got rid of the mold. With the rain yesterday, the water is coming into the basement from an exterior wall above where they opened up the wall.

There is a foundation crack with lateral movement in the rear of the house. Many repaired cracks around the foundation. Need to find out if this is more serious asap. My client is purchasing this home and we need to know the cost to repair or if this is a structural issue. Thanks

Foundation concerns and sump pump installation
Project Location: Alexandria, VA
We are a GC, and have built an addition on our client's house. We added a foundation to the back of the house, and it is well waterproofed. The new slab is just below the top of the existing footing of the original house. The original foundation wall is 12" CMU. Water has been penetrating through the mortar joint between the orginal footing and the original foundation wall. We would like to use your service to stop this water penetration. Total lengths is approximately 25'. Please let me know if you need any additional information. Thanks.

I recently moved into a fairly old house that appears to have water coming in, as we can see it in the walls. After one of the larger storms we had recently, the carpet got wet from the water coming in right around the wall where we suspected it was coming in. Not sure if it's an issue with how the water is draining on the outside of the house (i.e. not being routed away from the house correctly) or there's an issue with the foundation, but we'd love to get this addressed.
