Light comming through all four corners of my entry door when closed? (See below)?

I've installed an masonite steel entry door (prehung). I noticed light is comming through all four corners of the door. It's not ovbious however, it gives me indication air is leaking. I was told by the guys at Home Depot a little bit of that is normal and you can repair by weather stripping. The door has a form compression strip all the way around the door jam. I notice there is this rubber submarine weather stripping you can buy and screw in along the entire jam. I was also told my door might of not been square. It closes, locks and opens smooth.

Answers:
Very common problem, The form compression strips need to be removed and replaced with new ones. Cut them about 2 inchs longer at each corner. However..were the weather strip pushes into the door jam you will have to strip back just the part that pushes in leaving that couple inchs of overhang. Masonite makes all sorts of door steal, wood composite and I hate every single one. Thier composite doors are the biggest pieces of crap but they are cheap and the other alternative is a solid door $$$$ I guess if we were all rich we would leave this probelem up to Jose'.

Mine did the same thing. It probably is that the frame isn't square not the door. Buy the weatherstripping and put it on. Walmart or your local hardware should carry it. Good Luck!!
Masonite Steel?
Never heard of that.
I thought masonite was a type of particle board, used to skin over doors.

Anyways, you could try removing the existing weather strip and replace with a thicker?

Hard to say, without seeing the installation.
Have you thought of turning the light off on the other side of the door
spray foam insulation...use a little at a time as this stuff expands immensely
go back to your home depot and call them friggin idiots, then go find a real door company and explain it to them, they should give you (after you buy them) small foam pads for your problem, they are like a ramp, start small and get bigger, only about 2x2 square, one side is sticky that goes to your door jam, just peel the paper off and pull back your weather stipping gently and put the bigger end in. there is no need to tear anything off, if you cant find any send me an email with your address and i will send you some
