In regards to dampness in Portishead structures, there are essentially three primary types:

Damp Proofing Portishead Somerset (BS20)


  • Penetrating Damp

  • Condensation

  • Rising Damp


These 3 primary forms of damp are discussed in more detail in this article, along with recommendations for prevention and resolution, in case you discover them in your home in Portishead.


Things like unsound brickwork, loose or broken roof tiles, cavity wall issues and damaged guttering are external factors of penetrating damp. Internally, cracked shower trays, burst or dripping pipes and overflowing basins or bathtubs, can trigger penetrating damp. If left uncontrolled, peeling or bubbling paintwork, broken or blistering plaster and dark damp patches on walls, will be the visible results of water seeping into the walls and woodwork.

If you've got a leaky roof and it has been left untreated for quite some time, it can cause wet rot to develop in your roof timbers. Even though it's fortunate that wet rot doesn't have an impact on brickwork, in a worst case scenario, you may need a roof replacement (very costly!) if your roof timbers become structurally unsound. An unusual musty smell, a "spongy" feel to your timbers and the appearance of black fungus growth, could all signify the existence of wet rot.

You should not panic however, because to prevent these problems happening, a few straightforward steps such as cleaning and checking your gutters and roof for leaks, examining pipework for leaks and repointing brickwork should reduce such concerns. As an integral part of an overall damp proofing service, your local Portishead damp proofing company will check all these aspects.


Condensation Damp Portishead UK (01275)

One of the most common forms of damp in Portishead properties, condensation is super easy to spot. When colder surfaces come into contact with warm, moist air, small droplets of water form on those cold surfaces. Poor ventilation in areas with high humidity, for instance in boiler rooms, kitchens and bathrooms, is the most frequent reason for condensation.

To avoid condensation issues, easy solutions include ensuring that you've got enough ventilation in the worst affected areas, and wiping up any water droplets whenever they appear. This might call for the installation or upgrading of air bricks, extractor fans and cooker hoods to help redirect the damp air outside of the building.

The best way to establish the key areas that play a role in the situation, is to have a detailed damp proofing survey carried out by an experienced Portishead specialist. Sometimes damp air can be sucked in from the outside, plainly making things worse. To effectively minimise condensation problems, airflow must be regulated properly. A reliable Portishead damp proofing technician is well qualified to offer solutions and advice in this regard.

Damp Proofing Quotes in Portishead Somerset


Since 1875, a damp proof course has been fitted as standard in all homes built in Great Britain. You might not have a damp course on your property or home in Portishead if it was constructed earlier than this. It's a possibility that your damp proof course might have been damaged in some way if you are experiencing rising damp issues in a property built after this date.

It can be difficult to distinguish rising damp, however some giveaway indications are; tide marks on walls, crumbling or rotten skirting boards and white powdery deposits appearing on walls or being found on floor surfaces. If you notice or think that you might have any of these, it's possible that you've got a rising damp problem.

Rising Damp Portishead Somerset

Remedying rising damp problems can be as simple as checking your home's external walls to see if you can see a damp proof course. In order to get an adequate degree of protection the DPM should be above ground level by at least 150 millimetres. If you find this gap doesn't exist, you could dig the earth away to increase it, or if this approach isn't possible, a higher damp proof membrane (DPM) will have to be put in.

If your damp proof membrane (DPM) is in order and the gap is not the root cause of the problem, dampness might be coming up through your floors and into your walls, which might be a more challenging issue.

Using a number of different methods, damp proofing technicians in Portishead can swiftly identify and eliminate rising damp. A damp proofing cream can be carefully injected into your walls if you've got a somewhat older house with no damp proof course, or it is damaged over a wide area. This special cream is injected with a nozzle into holes drilled evenly along the mortar joint, and before the cream can set it turns to liquid and penetrates into the adjoining brickwork creating a barrier that is repellent to water.

If the damp proofing cream treatment isn't suitable, or the damage to your membrane is too extensive, a brand new damp proof course may need to be installed. Whilst this sort of repair work is a fairly extreme way to solve rising damp problems, it might be the only effective solution in the final analysis.

Yet another option for minimal areas of damage could include painting with a waterproof (bitumen based) latex emulsion coating. Wood flooring, carpeting or tiles must be lifted before any work is undertaken, since it is applied beneath your floor coverings. This is particularly effectual in cellar areas as an integral part of the tanking process to create a room which is watertight. For extra protection in such problem areas, your Portishead damp proof specialist may advise the use of building paper (a foil backed specialist membrane) before the bitumen coating has dried completely.

Tanking: In areas of a property which are below ground, such as basements, "tanking" is the process where surfaces that are exposed are covered in a waterproof coating. Any plaster and wall coverings must be taken off and the surfaces properly prepared before any work begins, because this coating has to be applied at the base level of floors and walls. When this coating has been put on, it must be allowed to dry out completely before replastering any walls and decorating over the top of it. This is an exceptionally disruptive process because it needs to be applied to a whole ground floor or basement level of a property, and it is wise to get more than one expert opinion on whether this is the only answer to your damp problems.


Dehumidifiers are a highly effective way of reducing the moisture content in the air, hence for condensation issues they can help quite a lot. The fact that these gadgets primarily mask the cause of the damp and not get rid of it, is the main problem with dehumidifiers. A professional damp proofing company in Portishead will be ready to give you advice on the best solution if you are suffering from dampness in any part of your house.


As with just about any project, the best recommendations for a professional come from friends and family. When possible you should see if you can get at least three different quotations from a number of companies, and before signing up for any particular damp proof providers, you can ask to see professional memberships and accreditations, as proof of their integrity.

Look out for technicians holding the CSRT (Certificated Surveyor in Remedial Treatments) or the Certificated Surveyor of Timber and Dampness qualifications, or companies who are signed up members of the Damp Proofing Association or the Property Care Association.

Membership of either the PCA or DPA guarantees your preferred damp proofing provider is properly qualified and has acquired the required experience to carry out a top notch damp proofing service. In addition, it offers a guarantee over any work carried out by one of their members.
