Common Mistakes When Installing uPVC Casement Doors

Casement doors are less forgiving than windows. Here are the mistakes that cause problems.

Why doors are less forgiving

A casement door carries more weight and gets used far more than a window, so any error in seating or hardware shows up faster — as dropping, dragging, or failing to seal.

What to know

Look for this

  • Frame not seated perfectly true
  • Hinges not sized to the door weight
  • Insufficient fixing for the load
  • Sealing gaps at the threshold
  • Hardware not adjusted after fitting
  • Reinforcement skipped on the frame

The practical takeaway

Doors punish shortcuts. The weight and daily use mean a door fitted slightly out will drop or drag within months, where a window might have got away with it for years.

Questions

Frequently asked

What goes wrong when fitting uPVC casement doors?

Frames not seated true, hinges under-sized for the weight, insufficient fixing, gaps at the threshold, hardware left unadjusted, and skipped reinforcement.

Why do casement doors drop or drag?

Usually the frame wasn't seated perfectly true or the hinges weren't sized for the door's weight — the load exposes it within months.

Are doors harder to fit than windows?

Less forgiving, yes — the weight and daily use punish any error in seating or hardware.
