Sat off the banks of the River Ouse, Selby is a growing town south of York. This low-lying town is separated by the River Ouse which is prone to bursting its banks fairly frequently.

Damp problems in this area have been contained by recent flood defence improvements but still, exist in the properties close by the Ouse. Properties range greatly around this bustling little town, from Victorian Town Houses through to Detached, Semi-Detached and Terraced.

The older properties stated above tend to be the ones that require most damp prevention measures taking given the low-lying nature of the terrain.

Damp Proofing Experts

Damp proofing experts are specialists in detecting damp and in recommending and installing the right kind of treatments to tackle the various causes of damp in a property.

This expertise is vital because damp can appear for different reasons, and the treatment should be appropriate for addressing these causes.

It is also important to use damp proofing experts because if damp is left untreated, or even undetected, it can lead to structural damage to a building.

Typically, when these specialists investigate for damp, they will look at the symptoms and then find the root cause, by carrying out a detailed survey.

Once they have diagnosed the causes of damp, which could be anything from penetrating or rising damp to condensation, they will be able to act to remedy the problem and prevent further damp occurring.

They may carry out a rising damp treatment, install a damp proof membrane, or provide another damp proof solution.

Varieties of Damp

There are several varieties of damp, which can affect a property: penetrating damp, rising damp, dry or wet rot and condensation.

Penetrating damp is when water gets into a building’s fabric, often through old walls or building defects.

Rising damp is when moisture comes up through the walls of a building, through capillary action.

Dry and wet rot affect timber in a building and come from a fungus. Dry rot tends to be more serious, but both forms can cause damage if left untreated.

Condensation is when warm, moist air makes contact with cool surfaces, such as windows or uninsulated walls.

When deciding on a damp proof course or some other damp treatment, it is important to first understand the cause.

What Effect Does Damp Have on My Home?

There are different causes of damp, and all of them can have a bad effect on your home.

Condensation is the most common form of damp in the home, which is when moist air condenses on cool surfaces. Certain areas, such as bathrooms and kitchens, generate a lot of moisture, but in winter, when outside walls get cold, condensation can become a problem.

It can result in the appearance of dark mould around windows, and it can generate an unpleasant smell.

Penetrating damp occurs when water leaks through walls of a house. The damp may then spread across walls and ceilings.

The usual symptoms of penetrating damp are damp patches inside, which darken when it rains. These stains look unpleasant, and if the damp is left untreated, it can cause peeling wallpaper and damage to plasterwork.

Rising damp is when ground moisture comes up through the walls of a property, through the bricks and wall materials.

It may leave a tide mark, and can cause rotting floors and skirting boards, peeling wallpaper and crumbling plaster.

Damp can also be a health hazard, with mould spores causing respiratory problems.

It is important to deal with damp, which can involve a damp proof course or other rising damp treatment.

What Is Rising Damp?

Any building made of masonry can be susceptible to rising damp and therefore require the damp proofing of walls.

Rising damp comes from moisture in the ground rising up through the building’s bricks and mortar. This is through a process of capillary action, where the water comes up through the porous walls of a structure.

The moisture will rise up to a level where no further evaporation is possible, at which point it drops down again. However, it has by this time soaked into the walls. Generally, this is around 1.2m above ground level.

Some salt deposits may reach higher, through certain kinds of plaster, render and wallpaper.

A damp proof course prevents this from happening and dries out the affected walls.
