Where a report pairs spiral balances with the staff bead, what stays open about a sash that will not stay open?
What stays open is why the sash will not stay open. Spiral balances are spring tubes in the frame, used instead of cords and weights. The staff bead is the planted bead on the room side that holds the inner sash. A sash that drops may have a tired spring, a painted-in edge, or a bead that grips too hard. The survey paired the fittings. It has not renewed the balances, has not decided which cause it is, and has not serviced the window.

What is the fuller explanation?
A spiral balance sits in a tube in the jamb and takes the weight of the sash. A tired spring lets the sash drop. The staff bead is only a planted timber strip. If it is pinched, or painted to the sash, the sash may stick and then drop. From the room those causes look the same. The visit did not strip the bead and did not test the spring.
Tell the solicitor the sash that will not stay open was not diagnosed. A joiner can service the balances and the staff bead, which is ordinary window work and not something the home survey has specified. The lender has a description of fittings, not a repair schedule. Do not replace the whole sash because the spring and the bead were named together. The cause stays open until someone works on the window.
What should you ask your surveyor?
- Did you leave the cause of the dropping sash undecided?
- Were the spiral balances named without a spring test?
- Was the staff bead recorded without being taken off?
What are the typical next steps?
- Leave the reason the sash will not stay open undecided.
- Ask a joiner to service the balances and the bead if you need a cause.
- Tell the solicitor the window was not repaired or specified.

Do spiral balances mean the weight box is empty?
Often the cords and weights are gone where balances have been fitted, but this visit did not open the box to prove that. The pairing is balances with the staff bead. The sash that will not stay open was not traced into the jamb. An empty box, if there is one, was not inspected.
If the sash stays up for a moment, are the springs sound?
No. A brief hold does not test a spiral balance. Springs can support the sash and then let it creep. The survey did not carry out that check and did not decide the springs are adequate. The staff bead can also be holding the sash for a moment. Neither fitting was passed.
