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.

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

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.

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

Moisture-proof crawl space insulation

Does your crawl space have fiberglass insulation? Fiberglass is better suited for upper levels of the home. In dark, damp areas, this insulation type can absorb moisture and fall off ceilings and walls, creating a mess and the perfect nest for rats, mice, and other pests. That is why Clean CrawlSpace Inc. provides moisture-proof insulation, including:

SilverGlo™ wall insulation: Closed-cell SilverGlo™ crawl space insulation does not absorb moisture and prevents mold and rot. It not only seals and insulates but also features a radiant heat barrier. Plus, it drains water below the vapor barrier or to a drainage channel.
TerraBlock™ floor insulation: TerraBlock™ crawl space insulation is made from ¾" of closed-cell foam and features a padded, puncture-resistant design, perfect for crawl-on access. It is also compatible with our crawl space liner and easily integrated with our waterproofing systems.

Job Stories From South San Francisco, CA

Cold Air Fix, South San Francisco, CA

Ms, South in South San Francisco, always noticed cold air coming into their home but could never identify where it was coming from. Finally, they noticed cold air coming from under the floor! The Crawl Space!

They called us at Clean CrawlSpace Inc and we sent out one of our moisture control specialist to inspect the crawl space. He found many gaps between the crawl space and the floor of the home. Also, the crawl space was very damp and cold with mold growing in it. The insulation was starting to hand and most of it was on the dirt in the crawl space. To solve this issue we cleaned and re-insulated the entire crawl space. Then we installed a 20 mil thick vapor barrier that acts as a barrier from the cold outside air and sealed it to the foundation.

Our crews came out and performed the work. Now Ms, South is happy to report there is no more cold air coming into the home and their heating and cooling costs were lowered because the home was better insulated!
