What Does a Party Wall Surveyor Actually Inspect During a Site Visit?
On a site visit, a party wall surveyor inspects the shared wall, the rooms and outside areas the work could affect, and the drawings for the proposed work. They record what they see so the award can protect both properties. They usually visit both sides.
The party wall itself
They look at its construction, thickness, condition, height and any chimney breasts. They check for existing cracks, damp or earlier alterations. They consider what the proposed work would do to it.
Photographs are taken as they go. Measurements of existing cracks may be taken too, so that any later movement can be compared with a fixed starting point.
The neighbour's rooms
With access, they inspect rooms next to the wall, ceilings, and loft space. This forms the schedule of condition. It is best to allow the visit, because it protects your position.
The building owner's site
They look at where the work will take place, how access will be arranged and whether protection is needed. They compare the site against the drawings and notice.
Ground and foundations
For excavation, they consider the likely depth of foundations, ground conditions and drainage. Trial holes may be suggested. They may ask for an engineer's input.
What they do not do
A party wall surveyor is not doing a full building survey or a structural design. They do not approve the work for building regulations. They are concerned with the Act and the fair treatment of both owners.
Preparing for the visit
Have the drawings, notice and any structural calculations ready. Clear access to the party wall, including loft hatches and cupboards. If you are the neighbour, tell the surveyor about any past movement, leaks or repairs, because they are easy to miss in one visit.
Frequently asked questions
How long does a visit take?
It depends on the property and the work. Allow a good part of a morning for a house.
Do I need to be there?
Being present helps. If you cannot, ask what arrangements are possible.
Will they take photographs?
Yes, usually. They form part of the schedule of condition.
Will the surveyor test the wall?
Usually they inspect visually. Further testing or an engineer may be suggested if there are concerns.
