Damp Proofing




Damp is 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 treatment.

Rising Damp - rises up from the ground and as such only occurs at ground level up to a height of usually not more than 1 metre. It is evident by tide marks appearing on a wall, bubbling and crumbling plaster, spoiled external brickwork or render.

Penetrating Damp - caused by ongoing building defects which allow water to penetrate a building such as leaking gutters and cracked rendering, defective plumbing as well as environmental conditions such as prolonged periods of heavy rain and strong winds.

Condensation - occurs anywhere in a property and at any height (unlike rising damp) where there is lack of ventilation, airflow and high humidity levels. Black mould and streaming windows is the common sign.


Addressing the signs of damp


Not addressing the signs of damp can have far reaching consequences to a property as brickwork, plaster and surrounding timbers will continue to become more and more saturated. Damp patches will start to appear, plaster will begin to bubble and crumble and a tide mark and mould could be evident.  Adjacent timbers will be at an ever increasing risk to wood boring beetle attack and wet and dry rot. The result can cause extensive damage and weakening to the timbers and overall fabric of the property which will become increasingly costly and more difficult to repair.

Understanding how to treat damp to ensure long term protection requires a high level of technical expertise and experience which is where Proten Services can help.


Correct diagnosis is key



Central to our company ethos is to provide our clients with honest and professional advice. We understand the importance of a thorough diagnosis to identify the cause of the problem before deciding if any treatment is indeed required.

 A survey will involve the use of specialist equipment to obtain readings from the walls, timbers and atmosphere to build a moisture and humidity profile of the area. Our surveyor will be looking for the cause of moisture ingress points as well as assessing the overall site conditions such as internal and external ground levels, condition and situation of the building, type of building materials and any underlying problems as a result of the damp conditions.

Once the cause and type of the problem is understood, the correct solutions which will vary in their complexity can be recommended appropriate to the problem so ensuring long term protection to the property.
