American Waterworks Before & After
  • Crawl Space Waterproofing in Camp Douglas, WI
    Crawl Space Waterproofing in Camp Douglas, WI

    Crawl Space Waterproofing in Camp Douglas, WI

    Rick and Vicki S. of Camp Douglas, WI had water seeping through their crawl space, making them worry about mold, rats, insects, and other pests. They went online and came across American Waterworks and our crawl space waterproofing products. They called our office line and scheduled a FREE Estimate with our Design Specialist, Charles Haldeman. Charles went to their home, inspected their problems, and came up with a solution that fit their needs. Rick and Vicki were confident in the product and warranty, so they went ahead with the installation.  Our Foreman, Cole Brinkman, and his production team started the project by installing 1,431 feet of drainage matting, which gives the water that floods into the crawl space a channel underneath the crawl space liner. It is a useful piece of material in the process to keep any crawl space dry. Next, Cole and his team installed 1,596 feet of our CleanSpace Vapor Barrier, which keeps away odors, mold, termites, cockroaches, mice, and other pests that need excess moisture to survive. Rick and Vicky were both very happy with the work and had a great experience!

    Crawl Space Encapsulation in Ferryville, WI

    Charlene T. in Ferryville, WI came across our booth at the Midwest Farm Show in La Crosse, WI. She was concerned about the moisture in her dirt-floor crawl space. She felt like she was losing energy from that space, so she spoke with our Design Specialist, Dylan Woitas, who was at the show and learned about our crawl space encapsulation services. Dylan set up an appointment with Charlene and went to her home to evaluate the situation and design the best solution.  Our Foreman, Kiko Pena, and his production team installed a full perimeter of rim joist insulation which seals the rim joists and lowers Charlene’s energy costs. They also installed our crawl space vapor barrier which protects the space from moisture and potential mold growth. The combination of these encapsulation products turned the crawl space into a dry, clean and energy efficient part of the house. The process took a couple of days to complete, but Charlene now has a bright, clean and healthy crawl space and is saving money on her energy bill each month.
