re: Using Home Depot/Lowe's For Home Improvements

I would not. I used them for a similar project: replacement door w/sidelights. It seemed okay at first, but quickly the door began to sag & the installer was nowhere to be found. Disconnected cell number, Home Depot said the issue was between me & the installer, and I ended up fixing the problem myself. Door had to be replaced within three years due to his shoddy work (jamb rotted due to poor installation/water intrusion).

Keep looking. I don't know where you're located, but it shouldn't be too hard to find a decent carpenter who specializes in small repair jobs. Do you know any general contractors? They may be able to refer you to trustworthy, competent subs who want to pick up some work on the side/weekend.
