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.

~ 750 square foot crawl space has no vapor barrier or insulation. May require sump pump but definitely vapor barrier and entry/door replacements. Retains some water during heavy rain.
Vicinity of Hume Ave in Alexandria
Our basement walls have some leakage in virtually every rain storm, and as an older house, the foundation lacks footing drains. We would like to look at more and less expensive options for waterproofing the basement.

Cold floors in our master bedroom addition. Considering a vapor barrier and/or other suggestions to alleviate the cold flooring.
Vicinity of Bren Mar Dr in Alexandria
I had a basement wall start leaking a month or so ago during a heavy rain storm. I traced it back to the wall next to the driveway and found a long horizontal crack along the wall, and the wall being bowed out about half an inch from what I can see. There are two visible wall anchors and probably more behind the drywalled part. I also move the end of the exterior drain to flow onto the driveway, instead of into the garden bed. There have been several heavy rains since then with no additional water intrusion. I'd like to get an estimate for what it would take to repair/reinforce the wall. In the meantime, i've made sure not to park my car near that side of the wall as well. Don't want it to be the 1 ton straw that breaks the camel's back. Let me know if there's any prep you need to do or if you have any questions. On a side-note, there is a portion of my garage foundation that appears to be sinking slightly. While this is not an urgent issue, I would like an estimate on what it would take to reinforce that, as well if you do that.
Vicinity of Memorial Street in Alexandria
On days of heavy rain, one section of our Basement experiences heavy flooding. The area that water seeps in is always the same (about a yard in width). The water will suddenly come in after hours of steady, heavy rain. We have a pump that removes water which it sends out in the back yard, but it does not prevent water from coming in in this area. The affected area is on the Driveway side of the House. The phone number provided above is my office number.
Vicinity of Tennessee Dr. in Alexandria
While raining Monday I notice a wet spot on the floor in the room that houses the HVAC system in my basement.
