This is a must have when doing your crawl space encapsulation. I am fully confident this tape will keep all my seams sealed. Well worth the price.

High quality vapor barrier, worth every penny I paid for it.

Used the crawlspacevaporbarrier.com system with 12 mil walls and 20 mil floor. All products very high quality. Seam tape works as advertised and I wouldn't substitute a lesser product. Buy plenty- maybe 3 times more than you think you will need. Keep you tools sharp and clean from adhesive to avoid frustration.

Crawl Space Repair ships quickly, accurately and is always on their A game. Great company and products.

Got a quote from a company to install this system for me for $6,700! I went to Crawl Space Concepts after researching several vapor barrier products and ordered everything I needed for $1,200 including shipping. Installed the entire system in my crawl space in 2 days. The products were all exactly as described, high quality, easy to use, and relatively inexpensive. I am VERY pleased with the final results and thanks to Crawl Space Concepts, I saved $5,500!!
