The report mentions a loose parting bead next to the meeting rails. Has daylight through the closed sash been tested, or only named?
Daylight through the closed sash has only been named, not tested. A loose parting bead is the thin bead between the two sashes, seen unfixed beside the meeting rails, which are the rails where the sashes close on each other. A line of light is something the eye can notice. It is not a measured gap, a draught test, or a decision that the sash has failed. The survey has not decided the bead is the cause of the light, and it has not priced or specified a repair.

What is the fuller explanation?
The parting bead separates the two sashes. If it is loose, the sash can leave its groove and light can show at the meeting rails. That light can also come from a worn rail or from paint holding the sash off the bead. Naming daylight records that light was seen. The visit did not measure the gap and did not refix the bead to test the fit.
Tell the solicitor the loose bead and the daylight were visual notes, not a draught test. A joiner can refix or replace a parting bead and then see whether the meeting rails still show light. That small job is not a result already in the survey. The lender has no measurement of the gap. Do not replace the sashes because a bead was loose and a line of light was named.
What should you ask your surveyor?
- Was daylight through the closed sash only named?
- Did you record the parting bead as loose without refixing it?
- Have you left the meeting rails without a gap measurement?
What are the typical next steps?
- Treat the line of light as named, not measured.
- Ask a joiner to see the bead and the meeting rails together.
- Tell the solicitor there was no draught test of this sash.

Also asked about this
Does a loose bead mean the meeting rails are rotten?
No. Loose describes the bead's fixing. Rot in the rails would be a timber defect, and the survey did not call it that. The two sit next to each other in the sentence. One does not prove the other. The rails were not tested for softness.
If no light shows on a dull day, has the gap gone?
Not as a test. Daylight was named, not measured, and a dull day can hide a fine line. The survey did not return with a gauge. Absence of an obvious line later would not erase the note, and it would not prove the bead is tight. The gap stays unmeasured.
