Rising damp treatment

If your property has been affected by rising damp, then you may require a remedial damp proof course (DPC) to put it right. Peter Cox is known as the UK market leader in rising damp treatment. This is because our process has proven to be successful in the identification and treatment of rising damp.

How to treat rising damp

The most common form of treating rising damp is installing a remedial damp proof course (DPC) via damp proof injection. It is a completely safe, time tested and reliable form of damp proofing. In most cases, a DPC is the fastest and most cost-effective treatment to install. The video below explains our treatment process and how we install a remedial DPC.

What is a damp proof course

A damp proof course installed via the injection method is an ideal solution where the original DPC has failed due to age or deterioration. Damp proof injection is a fast, cost-effective process. It involves injecting a silicone-based damp proof cream into holes drilled into the mortar joint at the base of the property. The solution then penetrates the masonry and creates a water repellent barrier.

How damp proof injection works

Damp proof injections are an ideal remedial DPC where the original DPC has failed due to age or deterioration.

DPC injection is designed to seep deep into the brickwork. This prevents moisture from the ground rising up through the bricks by capillary action and causing rising damp. The chemicals have a consistency that allows the active component, silane, to be absorbed then line the capillaries before drying. This is what creates the water repellent barrier, meaning that capillary action can not occur.

Damp course injection is also an extremely long-lasting solution to damp problems. Once installed, damp proof injections are covered by our long term guarantee.

Step one: The damp survey

Other causes of dampness such as condensation and rain penetration can cause similar symptoms to rising damp such as damp patches on ground level walls, mould on the wallpaper, dampness in the skirting and a musty smell. This set of shared symptoms can make rising damp an easy condition to misdiagnose.

However, our surveyors are highly trained and certified by reputable trade bodies. This ensures that we will properly assess the situation and accurately diagnose the cause of your dampness problems after a thorough inspection of the internal and external walls. If our surveyors identify signs of condensation, penetrating damp, or other mould problems, they will be able to advise on damp proofing solutions for your property.

You can read more about our process on our designated damp survey page.

Step two: Remove any salt contaminated plaster from the walls

Internal walls and external walls affected by rising damp will often contain salts that have become soaked into brickwork and wall plaster. Our surveyor will first establish if plaster needs removed. If it does, our team will carefully protect your floor coverings while we remove the necessary wall plaster back to bare brickwork and treat salt contamination on the wall surface

Step three: Install the damp proof course

To install the damp proof course, our technician will use a concentrated thixotropic silane/siloxane 'cream'. This is injected into the mortar bed joint of affected walls just above floor level. This forms a barrier against rising damp. Our solution is recognised as the highest concentration damp proof cream available.

As the cream dries it will create a water-proof resin within the wall to prevent any rising damp problems from resurfacing.

Step four: Replaster the wall

Once the new damp proof course has been injected, we can then replaster any internal walls that had plaster removed in step two. For extra protection, we use our salt retardant wall plaster. After the drying out period you are free to redecorate the wall however you wish.

The application of a damp-proof membrane can help the replastering process as it works as an excellent key for replastered walls.

Methods of rising damp treatment

If a conventional chemical treatment is not appropriate for your property, an alternative solution could be to use an Elecktro Osmotic System.

Using a small electronic charge, electro-osmotic systems repels the rising water from the wall and back into the ground. This allows the walls to stay dry. The main benefit here is that drilling on the outside of the property is kept to a minimum. It is also ideal for historic buildings as the system can be removed if necessary.

How much does it cost to treat rising damp?

There is little point in offering an average cost for rising damp treatment. The price is dependent on the severity of the problem and any structural factors specific to the design of your property. Naturally, if the rising damp problem is localised to one small area on a particular wall, the damp proofing cost would be less than if all ground level walls were affected.

No reputable firm would be able to provide an estimate of price without first sending a qualified surveyor to attend the property. This is to ensure rising damp is in fact the culprit and not condensation or rain penetration. If you think you may have identified rising damp then you can discuss it with our contact team by giving your local branch a call, or book a survey online.

Does rising damp treatment cause dirt in the house?

Installing a remedial DPC and removing salt contaminated plaster can of course result in dust and debris entering your home. Our specialist damp treatment team are equipped with top-of-the-line dust extraction units from Hilti UK. This is part of our commitment to leaving your home in a safe and clean condition ready for you to inhabit straight away.
