Penetrating Damp Treatment

Penetrating damp is a problem that can affect all buildings old and new.

Penetrating damp can be damaging to a property even if it does not pass all the way through a wall making its way into the interior of the property, it can often lead to other damp problems such as wet rot to nearby timbers, damp and perished plasterwork, increased heat loss through walls, musty smells, frost damage to brickwork and also unsightly water marks and residue lines to both the interior and exterior.

What is the cause of penetrating damp issues?

The main causes of penetrating damp are where water is allowed to enter the building usually through some sort of crack or defect to the brickwork or even a poorly sealed window.

Penetrating damp can be caused by a wide spread of building defects and can sometimes be difficult to diagnose, our expert surveyors know exactly what to look for with years of experience in the field. Here are a several common causes:

  • Leaking guttering and down pipe systems
  • Cracked or defaced brickwork
  • Perished mortar pointing
  • Poorly sealed windows and doors
  • High exterior ground level

It is quite normal for brickwork to soak up a degree of moisture which will naturally evaporate causing no harm to the masonry but it is when the brickwork is allowed to become constantly saturated that penetrating damp problems will arise and only get worse. If you are experiencing any of the following problems you may have a case of penetrating damp:

  • Perishing plaster
  • Water marks and stains internally and externally
  • Rotting timber leading to wet & dry rot
  • Mould growth
  • Damp smells
  • Cold walls
  • Spotting (damp patches at high or low level)

Our solution to penetrating damp:

Firstly our expert surveyors will carry out checks to determine the exact cause or quite often multiple causes of the penetrating damp. We will then carry out the necessary repairs to prevent the ingress of the moisture.

Once the initial causes have been correctly dealt with we will then install the necessary products to the affected areas such as our damp proof membranes, Liquid membranes or chemical plaster additives.

Any affected timbers will be removed and replaced if required before the area is treated with fungicidal chemicals to ensure that there are no future issues with wet or dry rot.

If our surveyors find any issue with the exterior floor levels being higher than the floor level to the interior of the property otherwise known as bridging of the damp course we will take measures to excavate the high ground or create a soak-away to ensure the sodden ground no longer sits against the brickwork causing it to be constantly saturated.
