  • Penetrating Damp

  • Condensation

  • Rising Damp


To find out what the probable factors behind such damp problems are, and how you can fix them, continue reading...


Issues like porous brickwork, broken or loose roof tiles, blocked cavity walls and defective downspouts or gutters are all external factors that can cause penetrating damp. Inside your York property, penetrating damp can be a result of burst or leaky water pipes, overflowing bathtubs or sinks and damaged shower trays. If left unchecked, damp, dark patches on walls, blistering or broken plaster and peeling paintwork, will be the obvious outcome of water seeping into the walls and woodwork.

Roofing timbers which are continually damp because of a leaking roof, can develop wet rot if this isn't treated. This could prove to be very costly, because if worse comes to worst the structural integrity of your roof timbers could be compromised, with the result that you are going to need a whole new roof. There are several indications of wet rot that are not hard to spot, the main ones being; the appearance of black fungus on woodwork, a "spongy" feel to the timbers and a musty smell.

Simple steps like cleaning and checking your guttering & roof for leaks, examining piping for leaks and repointing brickwork, can be the basic preventative maintenance measures. If you employ the expert services of a knowledgeable York damp proofing provider, they will check all these aspects as a part of your complete damp proofing program.


Condensation Damp York UK (01904)

One of the most common forms of damp in York homes, condensation is extremely easy to identify. When warm, moist air comes into contact with a cool surface, water forms as tiny droplets. It often forms because of inadequate ventilation in areas where there is high humidity, i.e. boiler rooms, bathrooms and kitchens.

To minimise the impact of this problem there are two steps that you can follow. You can wipe away any droplets of water as soon as they arise, and you can make certain that there is enough ventilation in areas that suffer most from condensation. Redirecting moist air outside of your home in York, by upgrading or fitting extractor fans, cooker hoods and air bricks, will help you to resolve this issue.

By conducting an in-depth damp proofing survey, a reliable York company will identify any spots where moist air is drawn in from the outside, simply exacerbating the condensation problem. A specialist in this industry will be able to provide advice, information and solutions on this matter, because to ensure that condensation issues are controlled, any air circulation in the home must be effectively regulated.

Damp Proofing Quotes in York North Yorkshire


Homes constructed since 1875 in the UK have required a damp proof course or membrane to be installed as standard. You may not have a damp proof course on your property in York if it was built earlier than this. It's possible that your DPM could have been damaged somehow if you are experiencing rising damp issues in a house built after this year.

Although tricky to distinguish, rotten or crumbling skirting boards, tide marks on walls and white powdery deposits appearing on walls or being discovered on floor surfaces, are all giveaway clues that you might have rising damp. Whilst the existence of these isn't conclusive, they are all indications of rising damp.

Rising Damp York North Yorkshire

Remedying rising damp problems can be as straightforward as checking your outside walls to see if you can spot a damp course. For satisfactory protection it should be 150mm (approximately 6 inches) above the level of the ground. You can dig away the surrounding earth to generate this space if it's currently not enough, or you can put in a higher DPM if the first option isn't possible.

If this isn't the root cause of the problem and your DPM is correct, there might be more serious issues to resolve caused by the moisture rising up from the ground beneath, up through your flooring, and into your walls.

York damp proofing specialists will quickly be able to determine the cause of your rising damp, and using a range of techniques will quickly resolve the problem. If you've got an older property with no damp proof course or one that is damaged over a significant area, a damp proofing cream (such as Dryzone or Permaguard) can be carefully injected into your walls. This special cream is injected with a nozzle into holes drilled at intervals along the mortar joint, and before the cream can cure it turns to liquid and soaks into the adjoining brickwork creating a barrier that is repellent to water.

If the damage to your membrane is too extensive, or if damp proofing injection cream is not a satisfactory treatment, you might need to install a brand new damp proof course. Though this is naturally a pretty extreme approach, it may be the best way to remedy your rising damp effectively.

For smaller areas of damage, another potential remedy would be to coat with a waterproof (bitumen based) latex emulsion. This has to be applied underneath your floor coverings, so carpets, tiles and wooden flooring must be lifted prior to work being undertaken. Also used as a part of the tanking procedure to create a waterproof room, this is a particularly effectual treatment in basement areas. Before the bitumen coating has has dried out completely, your York damp proofing technician may recommend a layer of building paper (a special foil backed membrane), for additional protection.

Tanking: In areas of a house that are below ground, for example basements or cellars, "tanking" is the process where any exposed surfaces are covered in a waterproof coating. Any wall covering and plaster must be taken off and the pertinent surfaces properly prepared before the commencement of any work, as this coating has to be applied on the base surface of walls and floors. Once this coating has been applied, it must be allowed to dry thoroughly before replastering the wall surfaces and decorating over the top of it. This is an exceedingly disruptive job as it has to be applied to a whole ground floor or basement level of a property, and it's recommended that you get more than one specialist opinion about whether this really is the only treatment for your rising damp problems.


Condensation issues can certainly be improved through the use of dehumidifiers, which are a highly effective way to remove moisture from the air. Owing to the fact that dehumidifiers basically cover up the cause of the damp and not cure it, there are disadvantages to this solution. If you are experiencing damp or mould in any part of your property in York, you should speak to a professional damp proofing company for the most reliable advice.


Friends and relatives should always be the first port of call when you're looking for recommendations for local specialists. Always get at least 2 or 3 different quotes from a variety of companies, and if you're in any doubt you should ask to see professional membership certificates and qualifications, before employing any damp proof services.

Watch out for contractors holding the Certificated Surveyor of Timber and Dampness or the Certificated Surveyor in Remedial Treatments professional qualifications, or local companies who are members of the DPA (Damp Proofing Association) or the Property Care Association (PCA).

Membership of the PCA or DPA guarantees that your chosen damp proofing specialist is suitably qualified and has the appropriate experience to carry out a top notch damp proofing service. This also offers a guarantee over any remedial work performed by one of their members.

Woodworm Treatment and Prevention York

Woodworm is a common problem that can cause serious damage to wooden structures, furniture, and other objects. The larvae of certain kinds of beetles gnaw away at the timber, causing it to deteriorate and weaken over time. Nevertheless, there are several ways to treat and prevent woodworm infestations.

To eliminate woodworm, the first step is to figure out the particular species of beetle that's doing the damage. As each sort of beetle necessitates a unique approach to treatment, it is vital to bring in a professional woodworm specialist who can perform an extensive evaluation of the scenario and prescribe the best plan of action. Only with a precise diagnosis and expert guidance can one efficiently combat a woodworm infestation.

One effective woodworm treatment method is the use of insecticides, which can be applied in liquid or gel form. This kind of treatment is really effective for minor infestations, but might not be suitable for more serious cases. For larger or more severe infestations, fumigation may be necessary. This involves sealing the affected area and discharging a gas into the space to kill off the larvae. Fumigation is a far more invasive treatment option and requires specialist equipment and training, therefore it's important to call in a skilled professional.

Preventing future woodworm infestations requires creating an environment that is not favourable for their growth. This can be achieved through proper management of the surroundings, including ensuring good ventilation, regulating humidity levels, and addressing any current woodworm infestations as soon as they are detected. By adopting these proactive measures, one can effectively mitigate the risk of woodworm damage and the associated costs.

In conclusion, it is necessary to use an experienced woodworm specialist in York to identify, assess, and treat any infestations to maintain the structural integrity of the building.

Cementitious Tanking

In cellars and underground spaces, cementitious tanking is a favoured method of preventing moisture penetration. This process necessitates the application of a cement-based water-resistant system to the walls and floors of the space or room. A range of grades suitable for various substratum is available for the tanking material, which can be pre-manufactured or mixed in-situ.

Cementitious Tanking York

If correctly applied for maximum effectiveness, cementitious tanking can provide a durable, long-lasting barrier against water ingress. Prior to application, the surface must be dry, clean, and free from any contaminants or loose material to achieve the best possible results.

A long-lasting, high-quality result can be attained by opting for professional installation by a certified damp proofing specialist. With proper installation, cementitious tanking can provide a reliable and effective solution for waterproofing cellars and basements in York.

PIV (Positive Input Ventilation) York

If you're looking to reduce damp problems within your property in York, PIV (Positive Input Ventilation) may be the ideal solution. If you've noticed mould and damp in your property or condensation on the windows then Positive Input Ventilation can help to reduce the humidity. It achieves this by continually circulating fresh air. Continuous replacement and refresh of air inside your home has been demonstrated to improve air quality, reduce pollutants and odours, and decrease dust mite allergens, thus improving day-to-day life for allergy and asthma sufferers. Installing PIV systems in an attic and having a reasonably airtight property are important considerations to keep in mind when opting for this solution. Just like water, air follows the path of least resistance, and any gaps and spaces around windows or doors can let fresh air out while allowing contaminated air in.

Condensation Control York

Control of condensation is crucial for maintaining a comfortable and healthy indoor environment. Through the interaction of warm, moist air with colder surfaces, condensation occurs, resulting in the formation of water droplets. Uncontrolled condensation can lead to the growth of mould, damage to building materials, and the deterioration of indoor air quality. To regulate the amount of humidity and promote air flow, good ventilation is necessary for controlling condensation. Reduction of condensation and temperature differentials can be attained by using double-glazed windows and insulation. By effectively managing condensation, you can prevent potential problems and create a more pleasant living or working environment.

In addition to reducing temperature differentials and minimising condensation, insulation and double-glazed windows can also help. Cold surfaces are prevented from coming into direct contact with warm, moist air by insulation, which acts as a thermal barrier. Reducing the temperature difference is one way to decrease the likelihood of condensation forming on surfaces like windows, ceilings and walls. Double-glazing is effective at preventing condensation by maintaining an even interior temperature. It features 2 panes of glass with an insulating layer between. (23095*)
