I would have liked a member of the management team to do an inspection following the completion of the job. A video of the space would be great. I strongly recommend you add post-installation inspections to your checklist. It should be inspected for quality control purposes. Bernie Benson

Everything was great except the price. I scored every category based on the service/work, but the price/value was a 6 out of 10. I have my own business and I know great service is expensive....but I don't know how you could justify the cost of materials (mass produced quality plastic sheeting) and 3 good men for about 10 hours to be worth $5,000., for well under 1000 feet of crawl space.

You are not the cheapest, but I have to believe you are the best. I was very unimpressed with Bay Area Moisture Control. My neighbors have watched this process with interest so you may get more business soon. Regardless, I thank you very much.

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
