Product was delivered as expected (3 days from purchase). Product was thick and fiber reinforced. I used two rolls of this product to complete the vapor barrier for an 1500 sq foot crawspace. It cost a little over $500. The cheapest install in my area was about $3500 for equivelant quality. It took about 20 hrs between 2 people. While it was hard work, it was well worth the savings and the product looks very good.

We had two reasons to use these materials in our crawl space: 1. Our radon level was measuring 14.4 pc/liter in our basement 2. Our house had a little musty odor when we would return from out of town trips. Our crawl space was dirt covered with pea gravel. After viewing the videos on your website I was convinced that I could resolve the above problems mentioned myself using your materials. I must say that with your information and materials we have reduced our radon radiation down to a safe level of 2.7 pc/liter and the musty odor in our home is gone. The total work took about 40 man hours but I saved approximately $4300 as a do-it-yourself project. Your materials were easy to work with and performed as you advertised. Thank you!

GuardianLiner is a great product! I am so happy with this crawl space barrier. It is easy to install and is tough material. It is well worth the cost.

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

Product is great to work with and is much better then the old 6mill
