They staked a thick plastic material called CleanSpace throughout our extensive crawl space, extensively and thoroughly cleaned all the floor beams and treated them with mold preventer and supplied us with a 25 year warranty (requires yearly inspection). As we were doing this for a home we were preparing to sell, it was nice to be able to have a 25 year transferable warranty for the new owners.
A-One Operation from start to finish. Donnie gave us an estimate that was right on -- he explained every step that would be done and exactly how it would be done. The crew that arrived to do the work were diligent, friendly, mindful of the house and extremely professional and knowledgable. We have subsequently moved to a new home and I will be having them out in the near future to do the same thing to it. I highly recommend them.
