WOW! You guys are the greatest. I called several times with several questions before I purchased the 12 Mil GuardianLiner™. Everyone I spoke to was very knowledgeable about crawl space encapsulation. We searched the web and I found you guys. I called and if you told me once you must have told me 20 times to seal the vents. I could not believe this would work. I did it and ordered the GuardianLiner™, the Foundation Seal Tape, the Waterproof Seam Tape, the Foundation Pins and a hygrometer. I would never have believed sealing the vents and encapsulating would be the answer to a problem we have had for over 30 years. Had we know this last year or 2 years ago, we could have saved a lot of money on insulation. I will definitely recommend you and your company to everyone I see who says they have a moisture problem in their crawl space. I have another friend whose brother paid around $10,000 to have his crawl space encapsulated on the eastern shore of Maryland. We did it for a fraction of the cost. Excellent, excellent product and excellent, excellent customer service from Bob, Caitlynn, and Larry. Kudos! Thanks again, GuardianLiner™ User and Believer

Great vapor barrier! The Foundation Seal Tape and Waterproof Seam Tape worked extremely well, too. My customer is very happy with the overall outcome.

You can't find a better product out there! I do tons of research to find the best product. Not only is a superior product but it is also cost effective. I've been in construction for over 30 years and have seen what the standard 10 mil black plastic turns into.

High quality and durable product

With the 6mil used on the walls, 12mil on ground, pinned and taped, it looks and feels great.
