Atlas was the last of several companies to come and assess what was causing a crack in our family room wall and making our back door unusable because we couldn't open and close it without difficulty. We also had seepage in the basement. Other waterproofing and foundation companies had us digging up our basement and installing extra sump pumps and drain tiles. The foundation companies said we should install piers for prices ranging from $5,000 to $18,000. (We ended up hiring a plumbing company to replace a broken sewer pipe outside with a new one installed in the basement to address wall seepage, but a large wall crack remained that we needed to address.) Atlas was able to meet our hectic schedule and arrived on time to assess our problems. The engineer they sent out was the only one of the companies who listened carefully to what was happening to our house. He carefully measured the family room looking for slope. He carefully checked for other cracks in the remaining walls and ceiling in the family room to establish cracking patterns. He checked out our foundation in the family room, which is a slab over ground but also an empty space where stairs from the basement leading outdoors used to exist. He targeted that area because that's where the largest slope and cracks were located. He was able to report how much our family room was sinking after measuring the room. He said he believed because the foundation was constructed over an open space, moisture had been gathering for years and rotting the wood that was the base of the family room. I mentioned that white spots formed on the walls in winter, and he said that information most likely confirmed his theory. The engineer was at our house for about an hour. He asked for a few days to work up an estimate. We told him we were going on vacation, so he had more than two weeks to put the estimate together instead. As promised, shortly after we arrived home, the estimate arrived via email, along with drawings and a detailed explanation. The engineer returned to our home to go over everything with us, and we decided to sign a contract. Everything continued to move smoothly. Workers arrived promptly at an agreed upon date and time, and got to work immediately. They were walking the long way around to the work site, so I invited them to walk through the attached garage. They moved their materials into the garage, and when they left, they swept the garage cleaner than it was when they started. As they were about to leave, I pointed out that drywall repair was supposed to take place where the crack was in the wall. They checked the contract and acknowledged that was true and immediately went to the store to purchase the materials they needed. They apologized for the oversight and repaired the wall, again leaving the family room spotless. This work was completed before winter began, and I waited to write the review because I wanted to see if the white patches appeared on the wall again as the temperature dropped. The engineer said the white patches should not appear. So far, so good. We have had cold enough temperatures for the white patches to appear. Also, the back door works perfectly now. We also had them fill the crack in the basement wall since it had started to seep after 18 years of dormancy. They injected a product in the wall and covered the full-wall-length crack with another material. So far, nothing has leaked even during substantial rains. We feel Atlas is highly professional. The engineer is the only one who really listened to our house problems and spent time with us. We had multiple foundation and waterproofing companies come in, but Atlas was the only one who we felt wasn't trying to sell us a product over what was really necessary. Hopefully, we will not need their services again, but if we did, we would call immediately.
