Products are fantastic and easy to use. My crawl space looks fantastic and clean. All the moisture from the Colorado flood that made its way upstairs is all calming down.

Wow, how happy am I that I purchased this product. Our basement now smells good, dry, and clean. Love how the white makes everything look clean.

My husband and I just completed our crawlspace encapsulation project using the 20ml Guardian Vapor Barrier from this website. It was a grueling job (not recommended for 58 and 60-year-olds) but we got it done. It took several weekends some weeknights, but well worth it. Humidity has already dropped 35%. Our next step is installing air ventilation system then we feel our foundation will be secure. A tip I would offer is to consider coverage of your crawlspace walls when ordering materials. Our house is about 1800 sq feet so I ordered two 1,000 sf rolls, but because of all the wall space and support pillars that needed to be covered I ended up needing to order an additional 1,000 sf roll to finish the project. So glad it's done!

After spending 3 years researching for a quality crawl space vapor barrier for my cabin - I went with your 20 mil vapor barrier. The sales staff were very helpful, reviewing the products required, and giving installation advice. The installation went great and I could not be more pleased with the products. Bright white, no off gassing, no more musty smell from the crawl space. The product exceeded my expectations (and that almost never happens for me).

After thorough research and 2 experts advise, this plastic was perfect for our small crawlspace. The 2 companies that we consulted tried to scare us away from DIY saying it'll smell like cat urine. Your website helped explain all those scenarios and they did not apply to us. It was one of our easiest DIY projects ever. The only issue was that we only used half a roll!
