Aqua Guard sent a knowledgeable representative to my home and he was able to figure out what I needed. Interestingly, when the crew cane to do the work and crawled further under our home, they found more work to be done. You might think "Right, they've 'found' more work" and not trust them. However, the work they recommended had been suggested by a contractor after purchasing my home and I had forgotten about it. In closing, let me say they cleaned up every day and made sure I was happy. I definitely would recommend them.
