Damp Proofing

What is Damp Proofing?

Damp Proofing is a general term used to describe methods and treatments of controlling moisture that has built up within walls and floors into the interior of the property.

It is important to have damp proofing specialists to tackle your damp problem, from the failure of a damp proof course (DPC) to high levels of water ingress and every other type of dampness in between.

Damp can occur for a number of reasons but it is typically as a result of a failing damp proof course (DPC), poor ventilation or poor property maintenance.

Compared to modern buildings, older housing was not specifically designed to stop damp problems by preventing the excess build-up of moisture. The reason for this is that older properties were built entirely from permeable materials with no attempt at damp proofing, unlike the construction of modern buildings.

Historically, most dampness was caused by the lack of maintenance which then led to leaks. However, the most common causes of damp are usually developed by inappropriate building work that stopped moisture escaping.

Damp Fact

The average house in the United Kingdom is exposed to around an average of 28,000 gallons of rainwater hammering down on its exterior per year. So it’s not surprising that damp can become a major headache for any property owner.

What Damp Proofing Solutions can be Carried Out?

It may come as no real surprise that dampness in properties is one of the most frequent problems encountered by property owners in the UK.

Spotting the right type of damp treatment to use can be difficult if the person is not fully qualified. Rising damp, penetrating damp and condensation can all look similar but each will need different damp proofing techniques carried out.

The most recognisable type of damp proofing that is used for getting rid of damp is using a remedial damp proof course. This treatment is applied into the wall to prevent the process of the capillary action (often known as rising damp).

What is a Damp Proof Course?

A damp proof course is a form of damp proofing treatment that is used to treat rising damp. There are different types of methods that can be used to repair a broken damp-proof course or the installation of a new one. The most frequently used is the damp proof injection which is the process of holes being drilled into the wall and a cement-based mortar is then inserted into the holes.

A damp proof course is not only effective against rising damp but can also stop other damp problems from occurring as well. Rising damp is often misdiagnosed by people who are not fully qualified, so it is always best to contact an experienced damp proofing company that is a member of the Property Care Association which could potentially save you expensive unnecessary treatment.

What is a Damp Proofing Membrane?

A damp proof membrane is a damp treatment that can stop damp coming up from the ground but also is also applied on the internal wall to stop dampness from getting through the inner walls of the property.

Once the water ingress has been treated the membrane creates a cavity that will allow for the evaporation of moisture behind the walls. The use of membranes is often as part of the cavity drain system which prevents water penetrating through the walls of the basement.

How to Damp Proof your Home

For any property owner with a damp issue, it is essential that the correct and most efficient damp proofing method is carried out to ensure that the property is made dry and damp free again. Our specialist surveyors can identify damp problems from both the interior and the exterior of the property.

The surveyors will also diagnose the damp issue that is affecting your home as well as providing a report detailing which treatment needs to be carried out. By failing to recognise the issue initially and leaving it unchecked further disturbances and problems may occur. Damp can spread and progress through your property, potentially leading to more serious problems such as dry rot and wet rot.

With there being so many different types of damp that can affect your property, there are also a number of damp proofing techniques that can be used to protect your property.

At Timberwise we want to help you identify the different types of damp that can occur within a property and explain what damp treatments are available for each of these problems. You can alternatively contact our damp specialists on 0800 288 8660 or request a survey online where our specialists team will then contact you to arrange a convenient time to visit.
There are 3 types of damp that can affect your property and these are:

Rising damp on walls

Rising Damp

Rising damp is a form of dampness that is present in walls as a result of the water underground (or next to walls) rising through the fabric of the wall. Click below to find out more about the what rising damp is and damp proofing treatments used to treat a rising damp issue.

Penetrating damp on walls

Penetrating Damp

The main solution to protecting your property from penetrating damp is to first identify the source of the water ingress that is affecting the property and then control the water ingress. The treatment for penetrating damp is very much dependent on the source of the moisture.

Condensation

Condensation is by far the most common cause of dampness in buildings, accounting for the majority of damp problems reported. There are 3 methods that can be used to protect your house from condensation.

Damp Proofing Walls

The most notable feature that dampness is affecting your property is from damp walls. Having damp present on walls can look unsightly and if not treated quickly, can cause serious damage to the structural integrity of the property. Having damp affecting your property is the primary cause of wood rot decay. Other issues that can occur from damp walls are health problems such as asthma and other respiratory issues.

Having damp specialists inspect your property can ensure that your damp problem affecting your walls can be treated from a specific form of damp proofing e.g. a damp proof course.

The sooner the damp walls are treated that the less chance there will be for further serious wood-rotting issues to occur and more expensive treatments needed.

Are Damp Treatments Guaranteed?

All damp proofing treatments are guaranteed with a long term guarantee of 10 years so you can be rest assured that all damp proof courses will be installed to effectively. If in the unlikely event that there is the recurrence of dampness on the walls then our damp proofing surveyors will be on hand to get rid of the problem at no extra charge.

How Much Does Damp Proofing Cost?

The cost of damp proofing can vary depending on a number of factors:

  • The size of the property
  • The level of damaged caused by damp problems
  • The location of where the damp is affecting the property (e.g. the basement compared to the bedroom)
  • The type of damp problem

All these factors will be taken under consideration when a damp specialist is conducting a survey at the property. By spotting the signs of damp earlier can reduce the cost of work carried out.

Get in Touch with Our Damp Proofing Specialists

It is vital to correctly identify the damp problem you have so that the correct damp proofing treatment can be put in place for your property. To correctly determine the form of damp treatment required, we would first recommend a damp survey from a fully qualified damp proofing company. Find out more about damp surveys by checking out our “what does a damp survey involve?” page.

Having a damp proofing specialist will be able to provide advice on the causes of the damp problem and how to stop it from causing serious issues such as wood rot.
