Hello, We would like to get a quote for installing a better drainage system and larger sump pump in the crawl space underneath our house. We would also like to get a quote for crawl space insulation. Thank you, Natasha
Davis Ave in Alexandria
We recently purchased an 85 year old home with no interior or exterious drainage system. In the recent extensive rain storms we have seen several puddles and significant pools of water in the basement. It appears to be coming from where the walls meet the floor. Our basement is unfinished.
Loyola Ave. in Alexandria
Leaky crack in basement - would like to see if someone can come out on Friday to inspect and provide estimate. Thanks.
Falkstone Lane in Alexandria
Our home was built in the late 60's and at some point had a French drain installed around the basement floor. Once in early June and then again this past Saturday we've had water seeping in under the baseboard along two walls. There's a window well on the one wall and it's been filling up with water. I've been using a submersible to try to remove as much water as possible and relieve some of the pressure, but there's definitely an underlying problem with the drainage system. Thanks!
Elmwood Dr in Alexandria
I have a section of my foundation that needs to be repaired. According to a report from a structural engineer it's going to require the foundation to be filled from the outside and supported with rebar. The section is about 10-15 feet., he suggested support every 24 inches or so. I also believe I have a cracked floor joist that is compounding the issue. I'm hoping to get an estimate for both repairs.

Old Stage Rd in Alexandria
Dale Street in Alexandria
We are in the process of buying a row house and just had our inspection done. The inspector had the below comment related to the crawl space and I wanted to get an idea of how much it would cost to fix it. I can also send photos. "Crawl space showing significant dampness all around. Uneven soft ground (soil) noted throughout. Dampness on foundation blocks present. No vapor barrier present or noted & insulation is getting very poor. ALTHOUGH A PUMP IS INSTALLED BUT IT IS NOT APPEAR TO BE SUFFICIENT TO KEEP THIS CRAWL SPACE DRY. NEED FURTHER EVALUATION & REPAIR SERVICE BY A CRAWLSPACE & WATERPROOFING SPECIALIZING PROFESSIONAL COMPANY."
CORNITH DR in Alexandria
I wanted to reach out in regards to a developing issue at our house. Since sometime this April I noticed a large crack running ~20' along the mortar joints of the cinder blocks in our back basement wall. At the time of discovery I made notes on the depth of the crack at each cinder block and over the last 1.5 months the crack hasn't changed in size (~3mm avg, 2 blocks are 5mm or larger crack depth). Let me know what the best approach would be from here as far as services or recommendations... structural engineer first, then you guys? Or what is the best use of everyone's time and money as well as reducing risk down the road?
