I chose Leherman & Leherman to re-do our patio awning, because we had a very good experience the first time we used the company, and after about 17 years, we asked them to give us an estimate to replace the awning as the original dry rotted. They came out and measured, and assured us a quality installation, however, when they installed the new awning, they used all the old rope and bolts nuts and hangers which were rusted and wobbly. Before the end of the first year, the awning began to collect rain to such a degree, that it would bow and we would have to go out and push up on the rain filled canvas to force the water off the rain and to keep the awning from pulling off of the house. When I called and explained the problem to Leherman Co., they said we'll come and check it out, but it will cost you $95., well, I didn't know how to fix it, so I let them do it, and after a few days, my wife said to me, did you notice the string that they used to fix the awning. Yup! a $95. string.
