We have always had the musty odor under the house and your product seemed worth checking into. Larry Hedman was very knowledgeable in the product and its very helpful in explaining it's benefits. He even emailed me the pcitures he took under my house. Raul Loyo and the installation crew were very good and kept my house clean during installation. R. Jetke.

Your Concept seemed interesting to us and we knew we had to address the dampness under our home. We were impressed with the installation crew. they were pleasant, easy to deal with and seemed intent on getting the job done quickly in order to save us money on trenching costs.

There was some lack of communication between Alex and David about where the pump should drain in the yard, and there were some questions for me that I wasn't sure how to answer.

Heard about you at the Home & Garden Show of Santa Clara & San Jose - we noticed a professional manner. You all were very professional every step of the way - you should all be proud to be a part of Clean Crawlspace.

Would like advice on closing up the existing crawlspace air vents. A lot of debris enter into the nice clean crawl space; not certain if I need air circulation as a building code or possible attempt to change this region into a conditioned space by installing air duct / ducts to provide heat

I have already convinced a neighbor to use Clean Crawl Space. This is some of the best money I have spent in terms of home improvements. The damp, musty smell is completely gone and the lower level of my home feels warmer. Everyone I came in contact with from Clean Crawl Space was professional. The workers were extremely clean and tidy and were proud to show off the finished product. From the first time I contacted Larry to give me an estimate to the time I finally decided to have the work performed did I ever get any sales pressure. I would recommend this company without hesitation. Thanks, Gord Nelson
