Representative sample window survey for estates
Start with a sample rather than a guess: enough windows, chosen across every type and exposure, to set the scope and budget before anyone commits to the full job.

A representative sample survey inspects a chosen set of openings across every window type, elevation and exposure on an estate, and reports the condition pattern, the likely repair-to-replace ratio and the scope of a full survey. It gives a managing agent or estate a defensible basis for budget and consultation before a full register is commissioned.

What is a representative sample window survey?
A representative sample window survey inspects a chosen set of windows across an estate or block, selected to cover every window type, elevation and exposure, and reports the pattern of condition rather than a full register. It gives a managing agent or an estate a sound basis for budget and consultation before committing to a survey of every opening.

Common questions
How is the sample chosen?
To cover every window type, elevation and exposure on the estate rather than at random, and the selection is agreed with you before the visit and set out in the report.
What does the report tell me?
The pattern of condition across the sample, the likely balance between repair and replacement, and the scope a full survey would need to cover.
Does the sample survey count towards a full survey?
Where a full register follows, the sample work feeds into it rather than being repeated, and we are happy to discuss how that works when you first get in touch.
How large does an estate need to be for this to make sense?
It is usually the right first step wherever surveying every window at the outset would be out of proportion to the decision you are trying to make.
Is the fee fixed before you start?
Yes, quoted in writing on the number of windows sampled, the access and the location.
