How to fix sagging store front glass door hinges.

If the screws look like they worked themselves loose simply tighten them and see if that fixed the problem. The screw closest to the door stop is most likely to hit the stud of the door frame. Inspect the door from inside or the side from where you can see the hinges. Reinforcement pivot hinges are used on wide or heavy doors to prevent door sag and as in this case to repair a sagging hollow metal door.

Cut slivers of wood slightly larger than the screw holes in the door. Tighten the hinge screws. If your door rubs near the top or drags on the floor use a screwdriver not a drill to tighten the screws. Position the door square and have someone hold it in place while you check the hinges.

It s common in sagging doors for the hinge side at the bottom to be tighter against the frame. The screw will go through the door jamb and into the wood stud of the rough door framing tightening the hinge and pulling the door jamb slightly toward the stud. Locate the gaps and where the door is tight. Installing the new reinforcement hinge adds a heavy duty pivot point at the very top of the door to support the door s weight.

Leah demonstrates how to correct a sagging door or door that is out of alignment with a tool called a knuckle bender. Start by threading nuts and positioning the turnbuckle. Drive a 3 inch flathead wood screw into the hole using a drill driver. With a drill you re more likely to over tighten the screw and strip the screw holes or chew up the screwheads.

You ll start by threading the coupling nuts onto either end of your turnbuckle. Apply a dab of wood glue to each sliver then tap them completely into the stripped out holes with a hammer. Screws magically work themselves loose over the years. Check out the knuckle bender online.
