“We had a mystery seepage in our basement–one area soaked once or twice a year. the patch would be completely dry 360 degrees around it. Bill diagnosed the problem, set in motion a solution, and Anderson executed results thoroughly and impressively. I look forward to not seeing dampness in the basement. Many thanks!”
