Windows, doors and glazing
What should you ask if two sash meeting rails no longer line up, so the fastener misses?
Ask about the meeting rails and the fastener, not about the cords alone. If one sash has dropped relative to the other, the rails no longer meet and the catch cannot close, which is a fit problem in the middle of the window, not by itself a broken cord, a locksmith's test, or rot unless the timber was soft. A surveyor sees the mismatch if the sashes were visible and does not rehang the cords.

What is the fuller explanation?
The meeting rails are the thick horizontal members that close against each other when the window is shut. The fastener is screwed to them. When they step apart, the fastener misses its strike or will not pull the joint tight, so the window whistles and the security catch does not engage. A cord fault can cause the drop, but so can a swapped sash, a worn pulley or a rail that has been planed. The survey should describe the step it saw and should not pretend to have found the cause inside the pocket.
A joiner can often ease, pack or rehang so the rails meet. There is no RICS price, and a new window is not the first reading of a missed fastener. Ask which windows were checked shut. A sash painted open cannot show the meeting. Do not call this a failed lock test: the home survey does not security-test ironmongery. If the rail is soft, that rot is an extra sentence. Single glazing in the same sash is not the defect you are looking at here.
What should you ask your surveyor?
- Which windows have meeting rails that do not line up?
- Does the fastener engage, or only look close?
- Was the timber at the rail soft?
What are the typical next steps?
- Ask a joiner to make the rails meet before you price new sashes.
- Do not force the fastener and split the rail.
- Say which windows were not closed, so they are not listed as checked.
Costs vary with the building and with who you instruct. Where this page does not cite a published figure, ask the surveyor, a relevant specialist, or your solicitor for a written quote. Do not treat a forum average as the price.
Also asked about this
Is a loose fastener screw the same fault?
No. A loose screw can be tightened. A rail that has dropped will still miss. Ask which one was seen.
Does this mean the cords are broken?
Not always. It is a reason to look at the hang. The survey has not opened the pocket unless it says so.
