To discover what the probable reasons for such damp problems are, and how you can resolve them, continue reading...


Exterior factors like: broken roof tiles, cavity wall issues, cracks in brickwork and defective drainpipes or guttering, can all be major reasons behind penetrating damp in a structure. Inside a building, overflowing baths or sinks, cracked shower trays and leaky or burst pipework, can lead to penetrating damp. If left to carry on leaking these things allow water to seep into the walls and woodwork, which in time result in broken or blistering plaster, damp, dark patches on walls and flaking or bubbling paintwork.

If you've got a leaking roof that's been left untreated for a while, the timbers of your roof can be affected by wet rot. Even though bricks and brickwork aren't impacted by wet rot, the timbers on your roof can experience severe consequences, and the whole roof may need to be replaced if it becomes structurally unsound. If black fungus appears on any woodwork and the roof timbers feel "spongy" to the touch, you might have a case of wet rot. When you spot any of these signs of wet rot, addressing the issue immediately is essential to prevent further structural harm and the potential need for expensive roof replacement.

Simple actions like inspecting water pipes for leaks, cleaning your guttering & roof and checking for leaks and repointing unsound brickwork, can be the basic preventative measures. As an integral part of an overall damp proofing program, your local Caernarfon damp proofing company will check out all these areas.


Condensation Damp Caernarfon UK (01286)

Many homes in Caernarfon suffer from condensation problems, and this is one of the most common factors behind damp. Small water droplets form on cool surfaces when they come into contact with warm, humid air. In areas where high humidity is present, such as: boiler rooms, bathrooms and kitchens, condensation arises due to inadequate ventilation.

There are two basic ways of addressing condensation, and these are making certain that the worst areas have ample ventilation, and wiping droplets of water away as they appear on surfaces. This might call for the installation or upgrading of cooker hoods, air bricks and extractors to help reroute the moist air outside of the building.

The most effective way to ascertain the key areas that bring about the situation, is to get an in-depth damp proofing survey done by an experienced Caernarfon specialist. Sometimes moist air can be drawn in from the outside, plainly making things even worse. The best way to adequately control condensation is to correctly regulate airflow and circulation, and your local Caernarfon damp proofing company will be able to give you advice and guidance on how this can best be accomplished.

Damp Proofing Quotes in Caernarfon Wales


Homes built since 1875 in the United Kingdom have been required to have a damp proof course or membrane to be installed as standard. If your home or property was built before this time it's possible that you may not have one installed. It is a possibility that your DPM could have been damaged in some way if you are suffering with rising damp issues in a house built after this date.

Rising damp can be difficult to identify, but some areas to watch out for are; crumbling or rotten skirting boards, tide marks on walls and a white powdery deposit forming on walls or being discovered on floor surfaces. Although the existence of one or more of these is not conclusive, they are all indications of rising damp problems.

Rising Damp Caernarfon Wales

The first step towards solving your rising damp should be to simply check whether you've got a damp course on the exterior walls of your home in Caernarfon. It should be 150mm above the level of the ground for satisfactory protection. If this is not the situation you may be able to dig away the ground to create this gap, or if this isn't feasible, you could install a DPM higher up.

If this isn't the problem and your damp proof course is in order, there may be more problematic issues to deal with caused by the dampness rising up from the ground beneath, up through your floor, and into your walls.

Caernarfon damp proofing experts will quickly be able to ascertain the root cause of your rising damp issues, and employing a range of procedures will soon solve the problem. If you've got a somewhat older property with no damp proof membrane or one that is damaged over a significant area, a damp proof cream (such as Permaguard or Dryzone) can be carefully injected into your walls. Holes will be drilled at intervals in the brickwork, and a special nozzle is used to inject the cream, which then penetrates into the surrounding brickwork before curing to create an effective, horizontal waterproof barrier.

In situations where damp proofing cream is not an appropriate treatment, or where your membrane is too seriously damaged, putting in a brand new damp proof course may be neccessary. Although this is obviously a pretty drastic course of action, it may be the best way to solve your damp issues in an effective way.

For less severe areas of damage, another possible option would be to coat with a waterproof (bitumen based) latex emulsion paint. Carpeting, tiles or wooden flooring will need to be lifted prior to work being undertaken, as it is applied beneath your floor coverings. This is particularly effectual in cellar areas as an integral part of the "tanking" procedure to create a watertight room. Your Caernarfon damp proofing expert might advise the application of building paper (a special foil backed membrane) before the bitumen coating has completely dried, additional protection in those problem areas.

Tanking: The process of covering exposed surfaces with a waterproof paint in a cellar or below ground area is known as "tanking". Because this waterproof coating must be applied on the bare surfaces of floors and walls, any wall coverings and plaster must be taken off before any work can commence, and the relevant surfaces properly prepared. You can replaster the walls and decorate over the top, after the coating has dried completely. You must always obtain more than one specialist's opinion on whether this is the only resolution to your rising damp, since this is a very disruptive process since it must be applied to a whole ground floor or basement level of a building.


Dehumidifiers are an effective way to remove moisture from the air, so for problems with condensation they can help. The main drawback with dehumidifiers in attempting to eliminate damp is that they simply mask the cause of the damp, not get rid of it. A competent damp proofing company in Caernarfon will be ready to give you advice on the best solution if you are suffering from damp in any part of your home.


As with just about any project, the most trustworthy recommendations for a local specialist come from friends and relatives. When possible you should see if you can obtain at least three different quotes from a variety of companies, and before employing any specific damp proofing services, you can ask to see qualifications and professional membership certificates, as proof of their trustworthiness.

Look for membership of and qualifications from bodies such as the DPA (Damp Proofing Association) or the Property Care Association, or contractors holding the Certificated Surveyor of Timber and Dampness or the Certificated Surveyor in Remedial Treatments qualifications.

You can be sure that your damp proofing provider is well qualified and has acquired the appropriate experience to perform a first class damp proof service, if they've got membership of either the DPA or PCA. Such memberships also means that there are guarantees for any remedial work performed.

Cementitious Tanking Caernarfon

A long-lasting, durable barrier against water ingress can be accomplished through correct application of cementitious tanking to achieve maximum effectiveness. For optimal results, the surface must be free from any loose material or contaminants and must be dry and clean before application.

Dehumidifier Installation Caernarfon

Dehumidifiers play a vital role in ensuring comfortable and healthy indoor air quality, particularly in regions with high levels of humidity. Without correct installation, the unit's longevity and performance will be compromised.

Dehumidifier Installation Caernarfon

It's essential to choose an obstruction-free location with a nearby power source before installing a dehumidifier. It's essential to ensure that the unit is placed on a flat surface and kept away from furniture and walls to allow for sufficient air circulation.

Setting up the drainage system correctly is the next step to prevent water damage or overflow. It could require attaching a hose to the unit or connecting the dehumidifier to a drain. The unit's efficient operation is dependent on regular maintenance, such as cleaning or replacing the filter.

The performance and benefits of a dehumidifier can be greatly improved by taking the time to select the right location and size. To guarantee a safe and successful dehumidifier installation, it's best to consult the manufacturer's instructions or seek the assistance of a professional. With proper installation and upkeep, a dehumidifier can improve indoor air quality, reduce moisture-related problems, and enhance overall comfort in a home or business premises.

Woodworm Treatments

Woodworm is a common issue that can cause significant damage to furniture, wooden structures, and other objects. The larvae of certain kinds of beetles feed on the timber, causing it to weaken and deteriorate over time. However, there are several ways to treat and prevent woodworm infestations.

The first step in treating woodworm is to establish the type of woodworm present, since different species call for different treatment methods. This is best done by a woodworm specialist, who can also assess the magnitude of the infestation and propose the most suitable treatment.

When it comes to treating woodworm, insecticides are one the most effective solutions, and these can be applied in liquid or gel form. These treatments seep into the wood and eliminate the woodworm larvae. For more severe infestations, fumigation could be required.

To prevent woodworm infestations in the future, it is critical to make sure that the environment isn't conducive to their growth. This can be accomplished by proper ventilation, maintaining correct humidity levels, and treating any existing woodworm as soon as it is identified.

Condensation Control

Condensation control is an important aspect of maintaining a healthy and pleasant indoor environment. When warm, moisture-laden air meets colder surfaces, condensation takes place and leads to the formation of water droplets. The consequences of uncontrolled condensation include damage to building materials, mould growth, and a decline in indoor air quality.

Condensation Control Caernarfon

Proper ventilation plays a crucial role in controlling condensation by regulating humidity levels and promoting the circulation of air. The use of insulation and double-glazed windows assists in reducing differences in temperature and minimising condensation. The creation of a more pleasant living or working environment is within reach through effective condensation management, preventing potential issues.

Using double-glazed windows and insulation can also help to reduce temperature differences and minimise condensation. Cold surfaces and warm, moist air are kept apart by insulation, which acts as a thermal barrier. A reduction in temperature difference makes it less likely for condensation to form on surfaces like windows, walls and ceilings. Double-glazed windows with 2 panes of glass and an insulating layer between are effective at maintaining an even interior temperature, which further inhibits condensation.

Another effective condensation control technique is to address moisture sources directly. Moisture is released into the air by activities like showering, drying clothes indoors and cooking. Preventing excessive humidity buildup in kitchens and bathrooms requires exhaust fans and proper ventilation. Additionally, using dehumidifiers in areas at risk of high moisture content can help maintain optimal indoor humidity levels.

Preventing potential problems and creating a more pleasant living or working environment can be accomplished by effectively dealing with condensation. Controlling the interior environment protects buildings and safeguards the health and well-being of occupants. Regular maintenance checks, including inspecting seals around windows and doors for gaps, can help you identify locations where condensation is likely to occur. As our understanding of building science and indoor air quality advances, new strategies and techniques for condensation control continue to emerge, providing even more effective ways to ensure a comfortable and healthy indoor environment. In conclusion, for a wide-ranging condensation control strategy, proper moisture source management, ventilation, insulation, and innovative technologies are all essential elements.
