Our garage door seals better now than it ever has. The installation was a little tricky - I don't see how one person could do it. We made sure the metal strips the rubber seal goes on were lined up as perfect as possible. Then we had to raise the garage door almost all the way up to have access to the start of the strips and maneuverability for the seal. We started feeding the seal into the channels. One of us on the end pulling. And the other keeping the seal length as straight as possible and feeding into the channels . . . while on ladders (remember, we had to raise the door to have access to the end of the metal strips). Like I said - a little tricky to install. But is good quality. Looks great. Seals great. And the cost was very reasonable.
