The bolts holding a glass balcony balustrade are rusting. What load test of that glass has the survey not done?
No load test of that glass has been done. The bolts holding the balustrade are rusting, which the survey can see and record. A load test would try how the glass and the bolts take weight. This inspection did not do that, did not pull a bolt, and did not certify the balustrade. Rust is a condition note on the fixings. It is not a test result, and it is not an external-wall form.

What is the fuller explanation?
Glass balustrades depend on the bolts and the channel that hold the pane. Rust says those metal parts have been wet and are corroding. It does not say how much metal is left, or whether the pane would stay under a person leaning on it. The survey stops at the visible rust. Building-safety papers for a block are a separate pack. They are not produced by photographing a rusty bolt, and the home survey has not written them.
Ask the managing agent, through the solicitor, for any inspection record of the balcony fixings, and keep that request separate from the survey sentence. If a load test is required, that is a specialist instruction, not a rereading of the rust. Do not tell a lender the glass was proved because the bolts were described. The survey has not load-tested it.
What should you ask your surveyor?
- What load test of the glass, if any, did you carry out?
- How much of the rust was visible without removing a bolt?
- Are you leaving any balcony certificate outside this report?
What are the typical next steps?
- Treat the rust as a visual note on the bolts.
- Ask the solicitor for any existing balcony inspection record.
- Do not describe the survey as a load test of the glass.
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
If the glass is intact, has the fixing passed?
No. Intact glass shows the pane has not broken. It does not load-test the rusting bolts and it does not measure what is left of the metal. The survey has not done that test. A whole pane can still sit in corroded fixings. The note remains the rust that was seen.
Does rust on one bolt condemn the whole elevation?
It condemns nothing by itself. It records rust on the bolts that were seen holding this glass. The survey has not load-tested the pane and has not surveyed every fixing on the elevation. Ask the agent what inspection the block already has. Do not stretch one rusty bolt into a certificate or into a clearance.
