Building Defect Diagnosis: What you Need to Know

Building defect

At some point in their lifespan, all buildings are likely to suffer from defects to one degree or another.

Even if the most thorough regime of maintenance has been used, you cannot guarantee that defects will not arise if, for example, the building has been constructed in a way that is inherently defective, or if changes occur and the conditions affecting the building that are beyond the control of those responsible for its care. Some of the most common defects could be anything ranging from a case of heavy condensation or cracking through the wall of an industrial unit.

In this blog post we will outline some of the key things you need to know about a building defect diagnosis.


What is a defect diagnosis:

Defects in buildings occur for a vast range of reasons – natural deterioration, poor workmanship, defective design and material selection, to name a few of the most common defect causes.

It is crucial that defects are diagnosed early on, both for reasons of safety and also to avoid unnecessary expenditure. Dependant on how early in the building life cycle a defect arises it may also be necessary to have clear causation in place so that redress can be sought against a negligent party such as a designer or builder.

As both building designers and building surveyors we are uniquely qualified and experienced in this field and are able to thoroughly investigate and report on matters including but not limited to the following issues:


Subsidence and ground heave

Cracking in buildings

Wall tie failure

Render and coating failures

Flooding and drainage issues

Material failures

Dampness and water ingress

Roofing failures


What will happen after a defect diagnosis?

You will receive a written report with recommendations outlining what steps to take. This may then be enough for you to engage contractors to carry out repairs. Alternatively, you may need to further investigation to assist the diagnosis, such as removal of floorboards or removal of plaster to open up the structure.
