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 leaky roof that has been neglected for some time, your roof timbers can be affected by wet rot. In the worst case scenario, you might even need to rebuild the whole roof, as wet rot can cause your roof timbers to become dangerous and structurally unsound. If black fungus starts to appear on any woodwork and the timber in your roof feels "spongy" to the touch, you may have problems with wet rot. If you detect any of these wet rot symptoms, it is imperative to deal with the issue promptly to prevent further structural harm and the potential for a 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.

By doing a detailed damp proofing survey, a decent Caernarfon company will find any areas where damp air is sucked in from outside, simply making things worse. It's essential that circulation and airflow is effectively regulated, in order to control condensation issues, and you can obtain guidance and information on this from a professional damp proofing company.

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 practice known as "tanking" is a specific waterproofing method for cellars, basements and other underground areas. This method involves applying a specially formulated waterproof paint directly onto bare surfaces. For this to be effective, all existing wall coverings and plaster must be removed, ensuring the coating is applied at the very base of floors and walls to create a watertight barrier. After application, the coating needs thorough drying before any wall replastering or decorative works can commence. Tanking is an extensive procedure, involving the treatment of the entire lower area of a property. Thus, it's prudent to seek opinions from multiple damp proofing professionals to determine whether tanking is indeed the best approach for your particular rising damp problems or if there are other less invasive but equally effective methods.


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.

The Benefits of Using Dehumidifiers

  3. Improvements in Health: Through the decrease in humidity levels, dehumidifiers effectively limit the growth of common allergens such as dust mites and mould, which are known to provoke respiratory ailments and intensify asthma and allergy symptoms.
  4. Protects Structure and Belongings: Moisture damage to possessions is prevented and the structural soundness of the building is protected by ensuring humidity levels remain low to avoid damp-related problems.
  5. Overall Comfort: The indoor environment's comfort and coolness, achieved by reducing humidity, serve to elevate the living conditions of those residing within.
  6. Prevention of Rust and Corrosion: In areas with excessive levels of moisture they help to stop metal tools and appliances from rusting and corroding.


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.

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.

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.
