Work Requests From Alexandria, VA
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?

Good Evening, I am about to have luxury vinyl installed in my basement, however after the carpet was removed, I noticed some cracks in the concrete floor. There are also a few cracks in the garage and on the side of the house that my home inspector noticed (I just purchased this home 10 days ago) and I would love to have everything addressed now. Are you available to complete this work? I can be available as early as Friday, May 4 for the work to be started. Thanks! Sarah

E Raymond Ave in Alexandria
I have an external access only basement that is a bit of a nightmare. The basement was back filled with dirt that was cemented back and has vapor barrier on top of it, there is water seeping in and I recently had an exterminator discover that rodents had found a way in, which is presently being take care of. I am looking to have all the insulation in the basement removed and replaced as well as have the foundation inspected/repaired and a solution to the water seeping in.

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.
