About Dampness in buildings

Dampness in buildings is about the presence of unwanted water. This must be addressed as it will breakdown the building fabric i.e. wood rotting fungi, insect infestation and moulds which creates a unsafe and unhealthy environment for the occupier.

An understanding of the pattern of dampness and wood rot in a building is paramount, and we have years of practical experience to draw on. Please contact me, I am here to help maintain your building and protect your investment.

Main forms of dampness in buildings

  1. Condensation
  2. Penetrating damp
  3. Plumbing leaks – Escapes of water
  4. Rising damp (rare form of dampness)

To assist analysing a defect with my educated eye. I have the following tools which help me understand the issue better:

Dampness will affect the building fabric via wood rot (dry & wet rot) and promote insect attacks (woodworm). Moulds are an effect of excess moisture and will break down materials, plaster, décor surfaces and leather shoes. The damp masonry will also erode due to biological processes, and pollution carried in the rain will also accelerate the break down the masonry.  To put is simply nature starts to recycle the building once you let water in.

Dry rot in timbers is a big concern for property owners one excess water get is into the building you may see, decayed timber, deep cracks in the timber grain, rusty looking spore dust, grey strands on timber and fruiting bodies of the fungus.

Our CSRT qualified surveyor has extensive practical experience (>25 years) in dealing with damp and wood decay in homes, churches, universities, historic houses, and museums. Due to this knowledge gained by exposing construction details and repairing, we can offer a solution to your problem.

Our photo gallery shows what will happens when dampness is allowed to penetrate the building and is not investigated quickly, and wood rotting fungi take hold.

Wet and Dry rot infection is relatively simple to bring under control.  By cutting off the fungus water supply quickly, but there may be reasons for the delay in drying out and is why timber treatments are used.

Give us a call to help you with your treatment and repairs, I am also aware of some conflicting opinions, and I will quickly clarify your concerns.

The first stage is to investigate the extent of the wet or dry rot with attention to the structural timbers, and these should be drill tested, where possible to find the extent of the rot.  Once the area of the infection has been exposed, it will also confirm the water source.

After which it is possible to cost for repairs and reinstatement, but generally, clients want to keep the two processes together, this is why a dual costing is based on previous experience are given.

Investigation Work

We also carry out dry and wet rot treatments and repairs, Woodworm treatment, Basement damp proofing, Rising Damp treatments

The Flir MR 77 detects Relative humidity, ambient temp and surface temperature.  And detects condensation
Flir 77 Moisture meter

Most of the condensation within a home is created by lifestyle. The level is the sum of external air plus the moisture generated within the property.

 A building normally buffers high humidity, which often trigger condensation in the home provided it is a brief time. Some modern materials, which now make up our home reduce its moisture buffering ability.

Severe condensation is caused when the interior atmosphere starts to get out of balance and humidity levels remain high (+70%RH) for extended periods of time.

Cure condensation

Flir infrared camera will show the temperature pattern on a surface and dew points were condensation will occur.

I suggest that you have an inspection carried out to help with diagnosis and producing an action plan.

Concisely, balanced heating and the correct ventilation at water production points will lower the level of moisture in your home.

Health issues

The young, elderly or anyone with a compromised immune system, should avoid areas affected by mould growth or dampness. It is not a good idea to sleep in any room affected by mould growth unless the area has been thoroughly cleaned.

Action Plan

To minimise condensation, maintain the ambient temperature above 15oC and ideally between 18-21oC, avoid heating the property for short periods as this will reduce its moisture buffering ability.

When showering or bathing keep the door shut and the area heated and ventilated until its dry.

Avoid drying clothes within the building, if you must, keep them in one room, which is heated and ventilated. A dehumidifier may be of help if you are unable to ventilate fully.

Check that you have the correct type of extractor fan in the bathroom and kitchen/utility room, ideally it should have a continues run setting or humidity control sensor (set at <60%RH). If you have no mechanical ventilation, then a damp control ventilation fan should be considered.

Open window trickle vents where fitted (but not in the room with an extractor fan).

Repair any defects which allowing water to penetrate the building fabric or any plumbing leaks.

Clean and dry any mould affected surface (which is less than 1m2) immediately. Larger affected areas may need professional cleaning.  Use an anti mould emulsion paint may be of help in sever situations.

Wash all affected clothing in a >50˚C wash to control mould (check labels for suitability).
