Doesn’t stick very well to block wall, even though it was bone dry. Sticks amazingly to the vapor barrier though.

BUY THIS AND DO IT YOURSELF.

This tape works great but I ran short twice. It is expensive and you will use more than you think specially around corners. I looked at using white duck tape at lowes for 7bucks.

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™.

These pins worked much better than I expected. I was most impressed with how well they hold on different conditions. Once I got the hang of drilling in a very tight crawlspace and keeping the mess down my project went fairly smoothly. This product along with the outstanding support and recommendations by the staff helped make my project a success.
