    Jamison Basement Waterproofing fixed this crawl space by installing crawl Shield moisture vapor barrier on the walls and floors. The CrawlSheild crawl space encapsulation system prevents moisture vapor from entering the home. To keep this homeowner's crawlspace floor free from odors and mold, drainage matting was placed underneath the vapor barrier.To help seal out cold air from the crawl space we sprayed close cell spray foam insulation in the pockets of the rim joist. We also closed the 4 open vents to prevent cold and warm air from entering the space.Project Manager Steve C Crew Foreman Dwight C

    Our project Manager Steve went out to meet with the homeowners and after a short period of time he knew exactly what they wanted to accomplish , because Steve was a crew Foremen for over 10years he knew how to approach this one . So first he proposal some wall Parging than we applied full vapor with a full drainage system with a Sump pump . Than to control the humidity we installed a high efficient dehumidifier to keep the humidity below 50% so they never have to worry about smells and odors .

      I 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.
