Surveys of timber frame houses

TRADA image

Professionals undertaking surveys of timber frame buildings should have an understanding of the overall design and typical detailing employed in this form of construction.

The approach to surveying a timber framed house is no different from that used for other methods of construction. There are many similarities with brick and block construction that can make timber framed houses hard to spot, but there are also tell-tale differences.

This Wood Information Sheet (WIS) concentrates on details where timber frame construction differs enough from masonry to suggest specific checks. Establishing the reasons for apparent faults may demand a more rigorous investigation, such as using a borescope to inspect cavities.

It has been updated to include reference to potential issues in newer houses caused by insulation installed in party walls.
