Bedroom damp caused by poor air circulation

Left untreated, damp can be bad for both your health (the mould and spores can aggravate respiratory problems such as asthma) and the health of your property: If any form of damp is left unchecked it can cause a number of potentially serious issues, including damage to decorated surfaces, or timber decay and even wet rot, which can lead to structural deterioration, and may necessitate major repair costs.

Penetrating damp in brickwork can cause major wall instabilities

Whether it’s damp proofing walls to prevent penetrating damp, treating rising damp, or dealing with condensation problems, damp proofing costs needn’t be prohibitive, though selecting the appropriate treatment will depend on the results of the damp survey. More »

Deep wall damp can be almost hidden behind plastering and wall paper

Penetrating damp: Once the source of the water ingress has been identified and repaired, treatments such as silicone water repellents, bitumen coatings, or a waterproof membrane can be applied to guard against future damp problems. More »

Brickwork affected by damp can cause serious problems for your home

Rising damp: Specialist creams are injected into the brickwork to form a waterproof barrier at the base of the wall; this will prevent water rising and penetrating into the building. Once the brickwork has dried out, the interior walls are re-plastered with plaster containing a waterproof additive. More »

Vapour Barrier Membrane System

As we enter the summer season, many homes are slowly recovering from the flooding that hit the UK. With many homes left with failed damp proofing courses, flooded basements and potential damp and mould growth within the properties, only over time can the property dry out completely. Our Damp proofing specialists are here to lend a helping hand in this stressful time, repairing the damaged caused from the extreme weather conditions.

Our specialists look specifically into helping properties avoid secondary flooding by providing a long term damp proofing solution for your property –  this enables the property to dry out naturally without effecting interior decoration. In the long term this can prevent problems such as mould growth and rotting of the structural timbers.

Vapour Barrier Membrane

One of the ways in which a surveyor can allow for a property to dry our naturally is to install a vapour barrier membrane system. Initially the damp walls may be dried out using an industrial fan at the time of the flooding, however this may not guarantee that the wall is completely dry all the way through. With the vapour barrier membrane system, this can be installed on the damp wall which allows air to the damp wall to dry out progressively without spoiling interior decoration by creating a gap between the wall and the plaster board. This allows the occupant to redecorate on the interior walls without the worry of damp coming through.

Our Damp Proofing Specialists deal with properties that suffer from damp on a daily basis, with over 45 years’ experience and knowledge at their disposal, they are able to survey the property to determine the type of dampness the property may be suffering from. From the findings of the survey, our specialists are then able to recommend the best solution for the dampness problem or a solution to alleviate a condensation issue.

Our damp proofing specialist

The surveyor will specifically search for moisture ingress within the property that has been affected by the floods. Inspecting the walls, masonry and timber flooring using a Protimeter, this enables the surveyor to investigate if there is a high level of moisture and if so the best way to remediate the problem. If the moisture content is too high the wall, masonry and structural timbers can be prone to timber decay, damp and mould. The surveyor can also take samples of contaminated plaster to determine if the plaster has been effected by hygroscopic salts from carrying out a speedy carbonate test. In the event the plaster is contaminated with salts the wall needs to be re-plastered to remove the hygroscopic salts to prevent further moisture entering the walls.

Ways to Improve Air Quality through Home Ventilation

There has been recent talk about the effects of outdoor air pollution from numerous European government bodies, which sparked the question here at the Damp Proofing Specialists of what the effects are of air pollution indoors?

The Importance of Home Ventilation

You cannot underestimate the importance of air quality and ventilation within properties, whether it be at work or home  issues with air quality tend to go undetected due to the lack of overall awareness of the situation.

There have been some improvements that have been put in place through certain building regulations by the British Standards for Construction. These regulations enforce certain air quality and ventilation guidelines. Most problems of poor ventilation within older properties are as a result of everyday living and may need more ventilation depending of the cause of the air pollution.

Mould Growth

Toxins Within Properties

In addition to poor ventilated properties causing damp issues there are also concerns surrounding toxic chemicals that are found within most households polluting the air within buildings. Toxins find there way into properties via common things such as cleaning products, smoking indoors, furniture and flooring and even pets.

If properties are not ventilated properly dampness and toxins can build up, this can result in damp issues (such as condensation) and the development of mould on interior wall surfaces. Gradually over time, mould stimulates the growth of the fungi, which is found as green and black coloured spots which will gather in clusters on walls and other soft furnishings. Therefore creating a health hazard for occupants of the property, especially those who suffer with asthma as the damp, mouldy conditions will exaggerate the problem. To help people improve the ventilation in your home and sustain a good quality of air we have compiled our list of the top 7 things you can do to keep the air fresh in your home.

Top Tips For Home Ventilation

  1. Carry out spring cleaning by regularly dusting and vacuuming as well as making sure to be changing or emptying the vacuum filter.
  2. Avoid using toxic products (these can be found in some aerosols) , try natural cleaning products for cleaning around the house.
  3. Toxins may also be found in cheaper furniture containing MDF or chipboard.
  4. Try and open windows when possible and keep a few indoor plants, the power of nature may surprise you! For more advice on which plants to keep look here
  5. Make use of extractor fans in kitchens and bathrooms to prevent condensation.
  6. Prevent overheating your home as this can promote growth of mould and circulate stale air.
  7. Last but not the least; prevent any smokers from smoking indoors.

In conclusion, air quality within a home can be easily forgotten and underestimated but by following a few hints and tips you can improve the environment you live in.

What is Chemical Damp Proofing?

There are a number of solutions for damp issues – the solutions depend though on what kind of damp issue the property is affected by. In most cases though where rising damp has been diagnosed there may be a need to install a new damp proof course. Following on from of our previous blog post on Electro Osmotic Damp Proofing, we now take a look at a different method of installing a damp proof course (or DPC)  –  chemical damp proofing.

What is chemical damp proofing?

Chemical damp proofing refers to the injection of a damp proof course using a damp proof cream as opposed to a physical damp proof course. Our product, known as Driwise, cures within the masonry wall to develop an impervious shield to rising dampness, this prevents moisture coming up from the ground into the cured walls. Adjoining abutting walls can also be isolated by applying a vertical damp proof course.

How is a chemical damp proof course installed?

The cream is injected directly into the affected wall. Having drilled a line of small, clean holes placed above ground level the holes are then filled with the Driwise solution using a low pressure injection method as can be seen in the photo to the left.

Once installed, the cream uses the moisture in the damp wall to diffuse before curing to form a water-repellent resin. It is a considerably faster acting system, requiring no solvent or water to enable injection to proceed.

Installation has minimal preparation and application time, resulting in minimal disruption to the occupants of any property as well as ensuring peace of mind and a satisfied customer.



What are the benefits of chemical damp proofing?

  •  A considerably faster acting system than other damp proofing methods, requiring no solvent or water.
  • Offers a higher degree of protection against rising damp than the old fluid injection systems that it is designed to replace.
  • A simple installation with minimum disturbance to the property
  •  Not injected under pressure, making it a low hazard, cleaner and safer solution to use than conventional chemical injection systems.
  • Non-caustic and non-flammable without spillage.
  • Odourless
  • Long-term guarantee.

What is Electro Osmotic Damp proofing?

There are various solutions to a damp problems – dependent of course on what type of damp problem the property is suffering from. In some instances there may be a need to install a new damp proof course – these can take the form of solid or chemical or as we are about to look at electric in the form of electro osmotic damp proofing!

What is electro osmotic damp proofing?

Installing electro osmotic damp proofing

Installing electro osmotic damp proofing

Electro osmotic damp proofing is for those people looking for a more scientific based damp proof course and uses electricity to prevent damp rising up. The electro osmotic system works by introducing a small electric charge in to the wall just above ground level.

This is done through use of titanium cathodes and anodes that are fitted into the brickwork just above ground level, these then draw power from the mains supply.

The effect of the small charge is to repel the rising moisture molecules back down the wall as the water molecules are drawn towards the negative electrodes.

As long as the positive electric charge remains the brickwork will remain free of damp.

How is an electro osmotic system installed?

The system is installed on the outside of the brickwork. Having drilled a series of small, neat holes just above ground level, anodes are inserted which in turn are linked by a connecting wire. This wire is then pointed into the wall resulting in the installation of a damp proof course that is fitted with minimal disruption to the property owner.

Benefits of electro osmotic damp proofing

– Unlike injected damp proof courses it is chemical free

– The system is suitable for properties of all types and ages

– A simple installation with minimum disturbance to the property

– A monitoring system can also be specified giving peace of mind the system is working

– Benefits from a long term guarantee

The system is proven to be very effective in difficult conditions such as stone wall, highly porus brick work and rubble filled walls where injection damp proof courses are not as effective.

Stopping damp problems

One of the questions we get asked frequently concerning damp is “how can I stop the damp problem returning ?” Stopping damp problems is certainly high on the priority list for many home owners – be it rising damp, penetrating damp or condensation. To help answer this question and to help you prevent damp becoming an issue in the future here are some top tips on how to stop damp becoming an issue.

Top tips on stopping damp problems

To help prevent damp becoming a problem in your property follow these  simple steps:

Maintenance – There is no substitute for good regular maintenance on  property. Checking gutters and down pipes and making sure they are clean and in good order is key to keeping water out of the property.

Keep moisture out! – One of the biggest causes of dampness in properties is condensation. By using vents and fans in bathrooms and kitchens condensation can be kept in check.

Check bath and shower seals – a leaking seal may only seem a minor issue but can cause problems with dampness leading to rot if left unchecked.

Act quickly – if you suspect a damp problem in the property get it checked out sooner rather than later. By leaving it the problem will not disappear it will only become more costly to resolve. Always use a qualified specialist to correctly identify what damp proofing treatments, if any, are required.
