Stop Air & Moisture
at the Threshold.
For Good.

As you know, I been involved in the construction industry supplying an array of products to thousands of contractors for over 40 years. And you know I am a stickler when it comes to moisture infiltration that is destroying our homes. I know firsthand that a lot of it is do to poor quality sealing products that just do not seal properly especially when we start running into inclement weather conditions. To be an effective tape it has to stick to the wall so well that water can't flow under the tape. If it doesn't stick, it is worthless. Your flashing tapes are the most effective air & water barriers I have ever used and sold, and your tapes stick better than any other tapes I've ever tried. Good job, thanks, John R.

Just want to THANK the Weather-Bloc team for their quick response in getting product to us. Your products are of great quality and our Tech's use your pan system on every door install. We have been now using this great product for over 6 years and will continue to be ordering it to prevent any future problems and leaks which hasn't occurred since using your pan system. Thanks, Holly

Hi Todd, good news and want to let you know I just got my Architect to spec the Energy Sill Sealer and new client to use it on their house that I will be starting to build shortly. After I showed them the test results I got back from a rater that did a blower door test on a previous house I completed which scored a phenomenal 0.36 ACH, they were extremely happy that I told them about the Energy Sill Sealer. The rater said it is the best score he has ever seen in doing over 8,000 test. I love the product and know it was a part of scoring such a awesome rating because I never got that great of a rating before I used your product. FYI: I will be promoting it to all my future customers and show them the huge benefit they will get using this product. For the money, no other product offers more energy savings. Thanks Eric.
