The Moisture Measurement System is a powerful and versatile instrument for measuring and diagnosing dampness in buildings and building materials. This product enables the surveyor to measure moisture levels of building elements such as walls, floors and building environments simply by switching between the three different modes of operation. In this way, a detailed understanding of the moisture condition of the property can be obtained.

Now the Hygrostick and Humistick probes measure relative humidity (%RH) and ambient air temperature (TAIR) in rooms or materials. They can be connected to the Protimeter MMS instrument Hygrostick For Timber And Damp Surveyeither directly or by means of the Hygrostick/Humistick extension lead.

• The surface temperature sensor (TS) is used when investigating condensation situations.

Free Damp Advice From Cannon Contractors

Understanding the type of damp that is affecting your property is important in order to cure the issue. This way you will not waste money on unnecessary work. Therefore it is vitally important toThe Type Of Damp.know the type of damp as treatments for the damp all vary. There are three common types of damp that can potentially affect your property.

  • Condensation
  • Rising Damp
  • Penetrating Damp

The type of damp as stated previously has a totally different treatment, though can be misdiagnosed – leading to incorrect treatment. So hopefully this post will steer you in the right direction. Condensation is probably the most common form of dampness affecting properties in the UK.

So Is Condensation A Type Of Damp?

This is where warm moist air condenses on a cold surface, typically external walls, as they are colder than the internal walls. The condensation period is from September to March and therefore condensation is generally a winter issue. Poor ventilation increases condensation issues as poor ventilation allows moist air to remain in the property that can then condense on cold surfaces. Condensation has increased over the years since the introduction of double-glazing, central heating and loft and wall insulation.  Modern property have more ventilation and is therefore an inherent problem for older property.  The older property cannot ‘breathe’.

So What Are The Symptoms Of Condensation?

  • In the first instance you will notice water beads on your windows – you may notice them on the morning when you open your curtains.
  • In rooms without windows and where the air does not circulate you may notice an unpleasant musty smell.
  • You may notice water droplets on windows or walls, see dark mould appearing, particularly on glass or around windows, and/or notice an unpleasant smell.
  • If left untreated mould will develop and spoil wall paper, clothing and other personal items.

So What Type Of Damp Is Rising Damp?

Rising damp is caused by ground water moving up through a wall or floor – referred to as capillary action. In newer properties a barrier is installed at the time of construction. This damp proof barrier, or damp proof course  as it is commonly called, is run horizontally around the property at 150mm (6 inches) above the ground.  The damp proof course is installed to stop rising damp.

So Why Is My Property Suffering From Rising Damp?

Depending on the age of the property damp proof courses were not installed in houses built prior to 1870’s, and as the property ages the original damp proof courses begin to fail. Rising damp is a destructive form of dampness and can lead on to other issues such as dry rot.

So What Are The Symptoms Of Rising Damp?

  • Externally white salts developing at the bottom of the wall, bricks may have started to spawl (loose the surface).
  • Internally to the lower region of the wall the plaster may show signs of damp causing wallpaper to peel or the plaster to blister.
  • More longstanding issues you may notice skirting boards to shrink and crack (this is a sign that your timbers are under attack from a fungal attack).

So What Is Penetrating Damp?

Penetrating damp is caused by water penetrating through walls and may spread over ceilings and is usually caused by structural problems in a building. Things such as faulty guttering or roofing, or cracks in the walls, which mean walls or roofs are regularly soaked with water are likely to cause this type of damp. It can also be caused by internal leaks, such as pipes under the sink or bath.

So What Are The Symptoms Of Penetrating Damp?

It shows in often-isolated areas and can any where on the wall.  If it is a gutter issue then the damp is noticed at the first floor ceiling area and starts to spread down the wall.  Penetrating damp is more common in buildings that have no cavities. These types of property allow the dampness to quickly effect the internal fabric of the building.

So What Next?

So you have a brief introduction into the different forms of dampness and what to look out for. In all cases it is recommended that you obtain professional advice on to correctly diagnose the problem. A reputable damp proofing company recommend treatments and give you an accurate upfront quotation before the work starts.
