    Project Manager Steve went out to meet with the homeowners and after listening to the homeowners concerns he knew right away that they wanted to keep the Basement dry all the time . Steve during his investigation even noticed problems in the crawlspace that would effect the health of the home and the previous company that look at the basement didn't even mention it to the homeowners so that really gave Steve the upper hand . Now the Solutions that we provided was a crawlspace complete encapsulation with a drainage system . We also installed a full perimeter drainage system around the basement with our thermal wall system that not only drain wall leaks but reflects heat back into the basement. We also installed two Grate Sump pumps with Battery Back ups for 24hr protection with discharge lines to move water away from the foundation . Now the homeowners can finish the Basement without any worries.

        Jamison was fantastic! They solved our water issue in the basement and were totally professional. They were neat, on schedule, honest and true to the estimate. The first big rain a few days after the work was completed, we noticed that there might be a bit of water still coming in. We emailed our contact at 6:30AM that morning (Saturday) with photos, expecting to eventually hear back from them. However, we heard back immediately and after a few email exchanges that morning, they were back in our house that afternoon to make some adjustments at no extra cost. The minor adjustments solved the problem. We were very impressed with the level of service and attentiveness. And now we are so happy to have a dry basement.

          want to give a "HUGE", thank you, to Steve C. and his team for installing a drainage system in my basement today. Steve and his workers were extremely friendly, and completed the project quicker than expected. They did an excellent job, at explaining the process and made me feel comfortable about my decision for choosing them. This has been one of the best, experiences, I have had working with a contractor. The best part of it all, is the company sent me a link to all the "work" photos , after the complication of the job. I would definitely use and or recommend this company to anyone looking to have work done at reasonable price, with experienced and professional contractors.

            I had Jamison come out to repair my broken sump pump and after the first rain, I noticed a leak in the discharge line. I called and they sent another tech to make the repairs but I still thought the tech should of tested the pump before he left But I’m glad they were able to resolve the problem 30mins after I called so they get 4 stars for that.

              Had a very bad damp moisture smell in my home and couldn’t figure it out until I went down into my Crawlspace and saw the floor joints dripping wet from high humidity. Steven Custus with Jamison Basement Waterproofing came out and knew exactly how to remedy the problem ! His installation crew was very professional and now I now can finally say the smell is gone! I would high recommend them!

                A few days ago I had a GrateSump and Drainage system put in my basement. The crew who did the work were outstanding ( Dwight & Derek ) They were polite, hardworking men. Dwight share with me everything that he was going to do before he did it. Their dust protection was just how the project manager Steven Custus said it would be . They did a very good job mixing the concrete and cleaning up afterwards . ( left my home cleaner than when they came )Dwight & Steve did a final walk through and explain to me everything I need to know about the system. They even offer to come back for a FREE annual maintenance next year to do a full inspection of the drainage system to make sure everything is working properly.Thank you so much! I'll pass your Business card on to my friends and Family.
