  • Penetrating Damp

  • Condensation

  • Rising Damp


These three primary kinds of damp are reviewed in more detail in this article, along with strategies for prevention and resolution, in case you find them in your property in Knaresborough.


Some of the external issues that might lead to penetrating damp in a property include: damaged or porous brickwork, cavity wall issues, loose or broken roof tiles and damaged gutters or downpipes. Inside a structure, it can be caused by burst or leaking pipework, overflowing sinks or bathtubs and cracked shower trays. Noticeable signs such as broken or blistering plaster, damp, dark patches on walls and peeling paintwork, all suggest that these issues have been left uncontrolled.

If you have a leaky roof and it has been neglected for a while, it can cause wet rot to develop in the timbers of your roof. Even though bricks and brickwork aren't affected by wet rot, the timbers on your roof can experience serious consequences, and the whole roof may need to be replaced if it becomes structurally unsound. A musty smell of rotting wood, the appearance of black fungus, and a "spongy" feel to your roof timbers, are all warning signs that wet rot is already a problem.

To prevent this, there are a few elementary preventative measures you can take: inspecting pipework for leaks, repointing unsound brickwork and cleaning and checking your roof & guttering for leaks. A competent Knaresborough damp proof service will check all of these areas in order to help prevent any future complications, as an element of fixing your damp issues.


Condensation Damp Knaresborough UK (01423)

There are lots of things that cause dampness in the home, but condensation is among the most common and easily noticed. Water forms as droplets on a cool surface, when warm, moist air comes into contact with it. Inadequate ventilation in areas with a high level of humidity, such as in boiler rooms, bathrooms and kitchens, is the most common reason for condensation.

Some of the more painless answers to condensation include wiping droplets away the moment they form, and ensuring that problem areas have plenty of ventilation. To help remove the moist and humid air from your building, you may need to update or fit cooker hoods, air bricks and extractor fans.

By undertaking a comprehensive damp proofing survey, a professional Knaresborough company will find any spots where damp air is sucked in from the outside, simply making matters worse. Airflow must be properly regulated to adequately control condensation, and a reliable damp proofing technician will be able to offer advice and solutions on this subject.

Damp Proofing Quotes in Knaresborough North Yorkshire


Ever since 1875, a damp proof course or membrane has been compulsory in all homes built in the United Kingdom. It is possible that you may not have one fitted if your property or home in Knaresborough was built before this year. If you're suffering with rising damp in a property constructed after this period it might be that your damp proof membrane or course has been damaged in some way.

It can be tricky to distinguish rising damp, however some giveaway indications are; white powdery deposits being found on floor surfaces or forming on walls, tide marks on walls and crumbling or rotten skirtings. While the existence of one or more of these isn't conclusive, they're all clear indicators of rising damp issues.

Rising Damp Knaresborough North Yorkshire

The initial step towards handling your rising damp problems should simply be to check whether or not you've got a damp proof course on the external walls of your property in Knaresborough. To be certain of an adequate measure of protection the damp course ought to be above ground level by a minimum of 150mm (approximately 6"). If you discover that this gap does not exist, you could dig away the soil to increase it, or if this process is not feasible, a higher damp course will have to be installed.

If your damp course is correct and the gap from the ground is not the explanation for the problem, dampness may be coming up through your flooring and into your walls, which could be a much more problematic issue.

Damp proofing experts in Knaresborough will quickly identify and eliminate rising damp problems using a number of techniques. A damp proof cream (such as Dryzone or Permaguard) can be injected into your wall if you have an older property with no damp proof membrane, or one that's damaged over a significant area. Evenly spaced holes are drilled at intervals in the brickwork, and a special nozzle is used to inject the cream, which then diffuses before curing to create an effective, horizontal water-repelling barrier.

If the damp proof cream treatment isn't suitable, or the damage is too extensive to your membrane, a new damp proof course might have to be put in. Although this is naturally a fairly drastic approach, it might be the best way to resolve your damp issues successfully.

The application of a waterproof (bitumen based) latex emulsion, is yet another possible remedy for minimal areas of damage. Carpets, tiles or wood flooring will have to be lifted before any work can be undertaken, since it is applied underneath your floor coverings. In basements this is an especially effective treatment, and will form part of the "tanking" procedure that is used to create watertight spaces. Before the bitumen paint has completely dried, your Knaresborough damp proof expert might advise a layer of building paper (a foil backed specialist membrane), for further protection.

Tanking: Tanking an area, like a cellar or below ground area, is the process of coating any exposed surfaces in a waterproof paint. Since this coating has to be applied on the bare surfaces of walls and floors, all wall covering and plaster must be removed before work commences, and the relevant surfaces prepared properly. You can replaster any wall surfaces and decorate over the top, after the coating has dried completely. Because it must be applied to a whole basement level or ground floor of a property, this is an extremely disruptive process. Therefore, it is advisable to bring in at least 2 or 3 damp proofing professionals to guarantee that this is really the only possible remedy.


Dehumidifiers are an effective way to remove moisture from the air, so for condensation problems they can be of help. The main disadvantage with dehumidifier use in trying to eliminate damp and mould is that they just mask the cause of the damp, not cure it. A professional damp proofing specialist in Knaresborough will be happy to give you advice on possible solutions if you're suffering from damp or mould in any part of your property.


The best recommendations for local specialists with regards to home improvement projects are usually friends and relations. Always obtain at least 3 or 4 different quotes from various local companies, and if you've got any doubts you should ask to see evidence of professional membership certificates and qualifications, before employing any damp proof services.

Keep an eye out for membership of and qualifications from organisations such as the Property Care Association (PCA) or the Damp Proofing Association (DPA), or contractors holding the CSRT (Certificated Surveyor in Remedial Treatments) or the Certificated Surveyor of Timber and Dampness (CSTDB) qualifications.

Membership of the DPA or PCA guarantees that your selected damp proofing provider is suitably qualified and has acquired the appropriate experience to provide a first class damp proof service. Furthermore, it offers a guarantee over any remedial work performed by one of their members.
