"Service was great from sales, to installation, to post installation support. Very responsive, very professional. It's hard to find in this 'space'--there are a lot of shady people in basement water damage/repair, and this place exceeded expectations. We've had our repair in place for 4+ years, with only 1 small issue on a wall seam crack, and that was fixed within 24 hours of reporting the issue. Stand up place! Thank you for such great service and support."

"I am having a truly unpleasant experience with 7th State Builders. I paid 14,450.00$ deposit in good faith. They were contracted to rebuild my deck, place a roof structure and screen on the deck. I trusted that they would complete the work. Instead, they took my money and one year later had not even started on the project. Not only did they fail to perform the agreed-upon services for the deck, but I was forced to hire an attorney to try and recover my deposit. Which I haven?t yet (over one year). Thus, creating unnecessary expenses to an already frustrating situation. I would strongly advise against using this company. They are unprofessional, uncommunicative, unreliable and clearly not trustworthy. My experience currently has been a complete waste of time, money and emotional energy. Dr. CLARICE BROWN "

"Gary arrived on time , inspected the basement and the perimeter of the house and told me that what I need is to work on the gutters and downspouts. If that doesn’t solve the issue then I should consider a French Drain and sump pump on one side of the house and that would cost me around $3500. JES tried to make me sign a contract for 32k a couple of days ago and they wanted me to basically destroy the entire finished basement on top of it. I appreciate Gary’s honesty, it’s so hard to find someone like that nowadays. I will definitely called Armored Basement Waterproofing if still needed after fixing the gutters. 100% recommended!"

"Been 7 years and everything is still tight! Repointed the block on the inside and painted it about 4 years ago. Paint is holding up. Squared the seal up on the outside and painted there too. Everything outside is holding up as well. The only company that didn't try to sell me a sump pump."

"Had a 5 foot long crack in my poured-concrete basement wall. It was not leaking, but I wanted to have it sealed regardless. Alek came on a Saturday, gave me his estimate, and then repaired the wall. He was very forthcoming by explaining that the repair was not absolutely necessary if there was no leakage, but I wanted it sealed anyway. He did a top rate job and I would not hesitate to use his services again."
