Damp in your house can be extremely dangerous for your home and your health. Problems to your home can vary from anything to décor damage, such as peeling wallpaper, or even damage to the structural integrity of your property. In terms of your health, it severely increases your chances of developing respiratory problems such as allergies or asthma.

As dampness ultimately leads to mould, your immune system will be weakened and your likeliness of catching other illnesses is much higher. We offer a water-tight way to protect your property.


The most common of the two varieties that can affect your home and commercial properties is rising damp. This is a process where water rises by travelling upwards through ‘capillary action’ into your buildings brickwork (or other materials)

Any damage, such as holes, draw up water due to the changes in pressure, leading to it spreading outwards once the moisture has intruded the wall from the ground. This type of damp can damage any surface including walls or floors.

Paintwork peeling and wallpaper wrinkling are classic signs of rising damp. If you spot these, it’s time to call in the experts for a free damp proofing survey or quotation. Our specialists at have a high level of experience behind them and will be able to get to the source of your rising damp issue. They will then recommend the best way to treat it, making sure your home is healthy again.


Penetrating damp is a key problem for areas with walls surrounded by earth, such as cellars and basements. It occurs because the whole wall is in contact with moisture, as opposed to rising damp which focuses on the base of the wall.

Water penetrates through the surface via ‘capillary action’ completely soaking into the wall. Penetrating damp can also be caused by broken guttering, cracked render, or damaged window sills. The penetration creates a cold environment where mould often grows.

This type of damp makes it extremely difficult to keep your home warm, as well as also causing respiratory problems if people commonly use the room. If you want to create a useable basement or cellar space, it’s vital you undergo basement tanking or damp proofing.
