Frames plumb, and holdfasts anchored into masonry

Why — act while you have leverage

A door frame fixed to plaster rather than into the wall works loose with use. It shows as a door that stops closing a year after handover, and the fix means opening the wall.

What — examine the details

What to look at

  • Plumb checked on both faces of the frame
  • Holdfast count per jamb, embedded before plastering
  • Frame not twisted — sight along it
How

How to check it yourself

Frames are checked plumb both ways and square on the diagonal before the wall closes on them. Holdfasts are embedded into masonry or concrete, at the number and spacing the specification gives — not nailed to the plaster.

Where this comes from: IS 1003 (Part 1) — timber panelled and glazed shutters; NBC 2016 Part 6 Section 5 for joinery (indian standard or building code)
