I am a resident of Tiffany House in Cedarhurst, NJ. Today I had my front door of my apartment replaced by your company. I want to tell you that the two fellows that installed it did an excellent job. I do recommend you very highly for the excellent job done. Thanks.

Just wanted to let you know that the “continuous hinge” repair your guys made on our entry door is fabulous! They did a quiet and efficient job of it. It blends right in with the door color and propped the door back up so it can close properly again. You saved us buying a whole new door.
Also, when your crew got the hinge on and the door upright again, they discovered they did not have to replace the threshold as expected so they left the old one in place.
Thanks and than your crew for me.

Good Afternoon Howard,
I can’t express in words how happy I am with the door, including the paint job (and I’m not just saying that because of my notarized letter). And your staff who installed the door were incredibly professional, friendly, and helpful.
Every person I dealt with at your company, have been great and I tremendously appreciate your work and would highly recommend you in the future.
