[Groesbeck Hurricane]

So I have a nagging question on a pre-hung exterior door I installed. Did three of them, one came out not so well.


On this one door in particular:

Door is fiberglass with a glass insert.

After installation (screwing in, putting in foam and silicone)

I have all four corners square, little to no deflection on the metal angle.

Using a four foot level the door jamb is even inside and outside on the hinge and opening sides. The level shows level.

Using a three foot level on the door jamb on the top all shows as level and no deflection noted.

Did not check the kickplate on the bottom.

The actual opening in the wall is neither square nor level but is close. The slab was level but not perfectly smooth.


Problem: After two days there is a gap of air after installation in the upper corner on the opening side.


Needed fix: How to correct this without taking the frame out (seems too extreme). Do not know if this helps/hurts but the brand of door is Masonite.

The other two doors/frames are doing fine.
