I found dealing with CrawlSpace Repair easy and efficient. In addition to the materials I purchased, I received very helpful advice—being a homeowner, not a professional. As to the products, the Foundation Seal Tape is absolutely excellent. Originally, I thought it was very pricey, but once I began using it, I changed my mind. This tape is great for this purpose. I used it to attach the vapor barrier to the foundation walls. Your 12 Mil GuardianLiner™ seemed very strong and should work perfectly. I’m sure there are other similar products on the market, but no customer of yours will go wrong with the GuardianLiner™.

We completed our encapsulation install about 8 weeks ago on our new house, all I can say is WOW! Our encapsulated conditioned crawl space is great. It is the only way to go. The crawl space air is clean, odor free with zero mold, and it is also critter free. Everybody that sees our crawl space is amazed. The efficiency payback is also going to be a great benefit for adding your product to our new house. I wanted to thank you, Bob, for all your help and great service!

It is a very good quality. I just had it installed in my crawl, so there is no way to rate the durability.

I ordered the 12 Mil Micorbal Guardian Liner to cover a 400 Sq Ft. orea where addition was on a crawl. Used liner, plus foundation seal tape, and waterproof seam tape. All these materiel were superior and very easy to use. In additon, the schematics and directions they supplied us made the job a lot easier! Very happy with the product. Thanks!
