HEADER SAG AND SLIDING DOOR CUT DOWNS

Whats The Problem?

A building under construction with wood framing.

The header is the culprit

A header is a beam that spans the top of an opening for a window, door or sliding door.

What is Header Sag? Header Sag is when the header above a door opening starts to sag down over time. This is due to the weight of the roof, combined with gravity, spread over the span of the sliding door opening.

When the header sags too much, it begins to pinch the rolling panels of the sliding door. The pressure wears down the rollers, damages the track, and the frame begins pulling away from the glass. The sliding door starts to feel heavy and before you know it, it won't roll at all. This whole process is completely normal, but it's a drag (no pun intended).

A1 On Track Sliding Door Repair can rebuild your sliding door panels to fit your existing opening. This will free up those heavy panels and have your doors rolling like new again.

Signs Of Header Sag

It's a Sign

Here you can see where the top edge of the rolling panel has been rubbing metal-to-metal against the header on top. If this sliding door is not repaired, the top of the rolling panel will cut all the way through the top jamb, or the door will become completely wedged in the opening and will not slide at all.

Leave this type of sliding door repair to a sliding door repair specialist. We are very familiar with this type of sliding door problem and specialize in this type of repair.

Sliding Door Cut Down

Does this door need a cut down?

The short answer is yes.
Pictured here is the top edge of the rolling panel of a sliding glass door. As you can see, the top edge of the panel is pushed up tight against the top jamb of the sliding door outer frame.

This is due to the header above the door sagging down. As a result, the rolling panel can not be lifted off the track in order to change the rollers;. it is wedged too tightly in the opening. This panel needs to be shortened in order to fit under the header, so it will function properly.

Stop fighting it and start sliding it!
