  • A 1 Foundation Crack Repair Inc

    I didn't hire A1 which, ironically, is why I strongly recommend them. I probably have a sinkhole under my foundation. I say that because the town recently filled a sinkhole on the street, mere feet from my front door. I've noticed some increased cracking, including the seperation of some drywall at the stud so I called around to see if any foundation repair companies could help. A1 called me right back. They offered great advice on whom I should consider contacting and why. Not only that, they helped me set an expectation about what I can expect and what it'd cost even though they don't perform the service themselves. That level of honestly and forthrightness is something to admire. He knew before he called me that he was going to refer me elsewhere. But he called anyway because he wanted to help. This is the kind of company people should seek out. Sincerely, Scot

    Paul pointed out right away major faults in the way the deck was built and how unsafe it was. The foundation post and beams were not up to code, He seriously thought the deck would collapse at any moment. He knew right away what needed to be done, explained in detail how it should have been built correctly and what he would do to make it safe and up to code. After taking photos of the stress points and problematic areas of the deck, he said he will get back to me to give an estimate of the cost of the project. In less than a weekend, he called me back as promised with the estimate. Despite his heavy work schedule, Paul gave priority to this project with a timeline to finish the work in a week. He finished in less than a week even when he discovered midway in his work that the middle portion of the deck had a bump because the opposite sides of the joist was sinking. Of which he ably corrected. I am very pleased with the quality of his work and the difference with the deck is like night and day. Where there were puny posts before, has now been replaced with proper sized posts imbedded in correct concrete piers for strong support. The privacy wall was perfectly replaced with a very appealing but definitely sturdy boards that can let in light but can withstand the winds. I am very pleased with the excellent craftsmanship that Paul has done on this project. I highly recommend him to any homeowner needing his services. You will only be satisfied by his superb work

    Our experience with Cory and Basement Improvements could not have been better! Cory was a pleasure to deal with - very professional, polite, and an extremely hard worker. He also communicated very well during the entire process. Our basement looks great and has stayed perfectly dry during many heavy rainstorms. Thank you Cory for a great great job

    The major ground water problem was fixed when Tony replaced the existing sump pump and installed a perimeter drain. Shortly after we moved in we noticed a few small puddles coming from a completely different source and even though Tony's work for for the initial source of the water, he came right over and sat with me in my basement during a rain storm to identify where the additional water was coming from and fixed it free of charge. Our basement has been dry as a bone since and that was six years ago. I don't recall the exact price paid for the service as the previous owner paid but we were given some say in which of the two contractors that were consulted would ultimately do the work.. Tony's price was about the same or slightly lower, because he came so highly recommended we chose him and we are happy we did

    It went perfectly. Tony and his team did a basement waterproofing job for us in 2010. Tony was completely transparent about the cost and the team was in and out as planned. We never had a problem in the basement after the installation, and Tony's team was back every year to do the required maintenance. I highly recommend Holt Landscape Construction for any project

    Doug was very responsive when I first called for an estimate. Scheduling was easy. The jobs I needed done took three days, and Doug's team (Francisco and Tom) showed up bright and early every day. Francisco took plenty of time explaining the work he was going to get done each day and stayed on schedule. The cracks in the basement were all repaired, and I haven't had any water infiltration problems in any of them since. The garage floor looks perfect. I think Francisco took a lot of pride in doing his work well, and it shows

    It went very well. The repair process was explained to me from start to finish. My only complaint is that the estimate that I received over the telephone was significantly higher than the actual cost. The difference was approximately $500.00.

    They called beforehand to confirm the appointment and arrived on time. We signed up for the service on the day of the estimate, since they were very impressive. Their work and materials have a lifetime guarantee. I’ve given them a deposit, but we haven’t received the service yet.
