Important Considerations for Wall Assemblies:

• Sometimes in older buildings, walls bow inwards or bulge outwards, depending on the type of structure and the age / condition of the building. Sighting down the exterior of a building from a distance may reveal these issues, followed by a formal building survey to discover the root cause of the deformation.
  
• Water stains on walls may point to infiltration from horizontal elements such as doors, windows and roof junctions.
• Operation of doors and windows may be affected by structural elements in walls that are deteriorating or failing.
