56% of English housing stock was built before 1965

English Housing Survey (2016)


Corsa Consultants are listed building surveyors.

Building defects occur for a variety of reasons, in new builds and older buildings. They may be obvious (patent defects) or hidden (latent defects).

In new homes, defects may be as a result of designers, suppliers or contractors. There is usually a ‘defects liability period’ once the build is completed to allow the contractor to remedy any defects.

However, according to the 2016 English Housing Survey, 56% of English housing stock was built prior to 1965. With the majority of homes over 50 years old defects are common.

In historic buildings, a defect may occur due to a combination of factors. This could be a change in use, poor maintenance, weather problems etc. Common issues include:

  • Damp and condensation

  • Roofing and pointing

  • Guttering

  • Structural alterations

  • Timber decay & infestation

  • Windows & doors

  • Subsidence


We will investigate and analyse the cause of defects and advise the best course of action. We will present cost-efficient options for remedial repairs; while also ensuring preventative measures for the future.
