We bought a beautiful house that contained rat droppings in the attic. The previous owner had used another company that did NOT resolve the situation completely. We hired Chris to come out and "resolve the issue." He did. To be extra thorough we hired him to remove all insulation in the attic, decontaminate the whole area, both in the attic and crawl space, seal up all open spaces and then spray fresh insulation in the attic. It's been two years and we are so appreciative to say we have not had a single problem. Chris is so good at what he does and so professional, I wish he had other endeavors so I could hire him to do other work on our home.
