The effects of damp on a property

Damp proofing companies will tell you, that ongoing damp can have far reaching consequences to a property as brickwork, plaster and surrounding timbers continue to become more and more saturated. Damp patches will start to appear; plaster will begin to bubble and crumble and a tide mark, mould and a musty smell could all be evident.

The damp conditions will mean adjacent timbers are at an ever-increasing risk to wood boring beetle attack, wet and dry rot. The result is damage to the overall fabric of the property and weakening to the timbers which will become increasingly costly and more difficult to repair.

What are the different types of damp?

Damp can be generally classified into three categories; rising damp, penetrating damp and condensation. Each type is caused by different issues and each will require a different method of damp proofing control or treatment.

Rising Damp

Moisture rises from the ground and if there is no barrier it will seep into bricks, mortar and plaster. Overtime, signs of the effects caused by rising damp will start to appear; tide marks on a wall usually to a height of not more than 1 metre above ground level, bubbling and crumbling plaster and spoiled external brickwork or render.

Penetrating Damp

Penetrating damp is caused most commonly by ongoing building defects which allow water to penetrate a building such as leaking gutters and cracked rendering and defective plumbing. Environmental conditions such as prolonged periods of heavy rain and strong winds can also be a factor. As such and unlike rising damp, it can appear anywhere in a property. Green mildew on brickwork, damp patches on walls are common signs of this type of damp problem.

Condensation can often present itself like a damp problem. However, unlike rising or penetrating damp, condensation can occur anywhere in a property and at any height where lack of ventilation, airflow and high humidity levels are a problem. Black mould and streaming windows are the common sign.

Damp survey: finding out the source of the problem

Damp proofing control methods can vary, ranging from improving ventilation, to a chemical damp proof course injection to clearing vegetation, or fixing a leaking pipe.  The first step we take is to carry out a site survey to understand the cause of the problem and assess for any resulting damage such as dry rot or timber decay or beetle infestation such as woodworm.  It is this understanding that is essential before recommending the remedial action that needs to take place.
