Estimate for crawl space barrier

Project Location: Berkeley, CA

Crawl space with bare earth and no moisture barrier. Ground is wet, and gets standing water when it rains heavily. Would like to get drainage, sump pump, moisture barrier, etc, installed. Goal is to reduce humidity in house.

Project Location: Berkeley, CA

Would like to do something about my crawl space because I think it's causing the house to be humid and also long term damage to structure. The crawl space is about 90% RH and the house is about 65-70% RH. House is 1,547 sqft

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.

Jon H. Jon H. San Rafael, CA

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.

From the beginning conversation with John to the end we were pleased with the level of professionalism shown by everyone involved. The installers were fabulous and equally professional! And clean--so clean! Many Thanks!

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

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
