Damp Detection

Damp is the main starting point for any kind of decay in a building and therefore must be addressed before, if not directly after any form of internal remedial repairs! There are various types of damp that can effect the internal fabric of buildings such as:

  • Penetrating Damp
  • Rising Damp
  • Condensation

Each of the above categories can be further sub-divided and the respective causes can vary for a number of reasons. It is up to specially trained surveyors to determine the cause and the affect of each case as the wrong diagnosis can have a detrimental outcome. The experienced surveyor will use all our specialist equipment to identify the tell tale signs and come to the correct conclusion.

Examples are:

  • The presence of salts and their type
  • Observations and conclusions gained during external inspections
  • Presence of damp proof membranes or damp proof courses
  • Internal environments that can cause condensation, such as over or inappropriate insulation installation, lack of ventilation, type of heating and individual living conditions
  • Moisture metres or a Hygrometer
  • And probably the most important tools, like; sight, smell and touch combined with common sense!
Sample Report
"Undertaking works to traditional buildings requires sensitivity and gentle care. We are all attracted to these structures by their character and features. Cornices, timber detailing, original windows and panelling, local stone and slate, original plasterwork and delicate paint schemes…. they all contribute to the sense of value we find in an old building, and their contribution to our streetscapes. In most circumstances with a bit of thought and care such features can normally all be retained, repaired and represented if the planning of the work is approached with knowledge and experience. Too often, due to lack of understanding or for commercial motivation, historic features are un-necessarily removed and lost during insensitive heavy-handed repair and renovation works. The service provided by Alder Specialist Surveyors, comprising technology and experience, can allow professionals and owners alike understand the true extent of decay, forensically identifying points of failure, and informing targeted invasive works only where needed. This results in proportionate cost-effective work, retaining the very fabric and character that attracts us to these buildings in the first place. I have worked with Pat for twenty years or more. I consider his skill, experience and technology essential when developing repair schemes on traditional buildings. His offer is based on a desire to find the root cause of issues, allowing my practice to specify good sound conservation repairs, returning the old buildings we all love to good health. "
