Age and type of house
Brick slips on a modern timber-frame house look like a brick wall from the street. What structure has that face not proved?
That face has not proved a brick wall, or any masonry structure carrying the house. Brick slips on a modern timber-frame house are a cladding that looks like brick from the street. The survey has recorded the appearance. It has not opened the wall, not found a loadbearing brick leaf, and not treated the street view as the structure. The frame, if it is the frame the particulars describe, sits behind the slips. The face does not prove it, and it does not prove the opposite either. Looks from the pavement stop at the slips.

What is the fuller explanation?
A slip is a thin brick face fixed to a backing. From the street the joints and the colour imitate a cavity wall, and buyers are used to reading brick as brick. On a timber frame the brick is often only the rain screen. The survey can note the slips and any crack or loose edge it saw. It cannot, from the pavement, show you the studs, the sheathing or the ties that hold the slips on. The structure remains the thing that was not proved.
Ask whoever knows the construction, or a specialist in timber frame, what the wall is built of, and do not brief them that the street elevation has already proved masonry. Tell the solicitor the survey recorded slips and did not confirm a brick structure. If works are planned, the backing matters more than the colour of the face. The report has not upgraded a cladding into a wall.
What should you ask your surveyor?
- Did the street face show brick slips rather than a proved brick wall?
- What, if anything, did you see of the structure behind the slips?
- Have you left the frame unproved by that face?
What are the typical next steps?
- Read the brick face as slips, not as proved masonry.
- Ask for the construction, rather than trusting the street view.
- Do not plan work as if the front were a loadbearing brick wall.
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 a slip sounds solid when tapped, is the wall masonry?
No. A solid tap is a sound from the surface. It does not prove a loadbearing brick wall, and the survey has not opened the face. Timber-frame backings can sound firm. The structure behind the slips remains unproved. The tap changes nothing about the frame.
Does a matching brick garage mean the house is the same build?
No. A garage can be masonry beside a timber-frame house with slips. The survey has not used one building to prove the other. The house face is still a face. It has not demonstrated the frame, or a brick wall, on its own.
