We had a hell of a time replacing our big
windows. So. Much. Cussing. I read some people don’t realize there are two steps to the gasket install. The final being squeezing a flap under the other flap. From the outside. I don’t know, but it was awful. If installed properly, I hate to think it could blow in. Yikes.
I have seen the work Shanos has done, top notch. So who knows...
