I have a Therma-Tru front door that is wood. I bought the unit about 8 years ago with two side transoms and a top transom. To make a long story short the door has a huge gap at the top and curves in towards the inside of the house. Therma-Tru claims to have a lifetime warranty. Therma-Tru came out, said the door was warped, replaced the door. I hung the door and the "space" is exactly the same. Called ThermaTru and they said they only warranty the door. To me, this is crazy and not sure who I could get to install/repair this. I am in the 18976/Pennsylvania area. Any recommendations?
