  • Penetrating Damp

  • Condensation

  • Rising Damp


Below you'll find information on what may cause damp issues in your home or business premises in Portland, and how you might set about fixing them.


Exterior factors like: defective gutters or drainpipes, blocked cavities, unsound brickwork and cracked or loose roof tiles, can all be primary reasons behind penetrating damp in a structure. Inside your Portland home, it can be a result of overflowing sinks or bathtubs, damaged shower trays and leaky or burst pipework. If left unchecked, blistered or broken plaster, flaking paintwork and damp, dark patches on walls, will be the obvious results of water seeping into the walls and woodwork.

Wet rot can arise in your roof timbers if you've got a leaky roof that is left untreated for some time. Even though it's fortunate that wet rot doesn't have an impact on brickwork, in a worst case scenario, you may need to replace the entire roof (extremely expensive!) if your roof timbers become unsound structurally. If a black fungus starts to appear on your woodwork and the timber in your roof feels "spongy" to the touch, you could have a case of wet rot. To avoid further harm and the potential need for expensive roof replacement, it's important to address any signs of wet rot promptly.

To help prevent this, there are a few elementary preventative measures you can take: repointing brickwork, inspecting water pipes for leaks and cleaning your guttering & roof and checking for leaks. As an integral part of an overall damp proofing package, your local Portland damp proofing company will check all these aspects.


Condensation Damp Portland UK (01305)

One of the most common causes of dampness is condensation, and lots of properties in Portland have problems with this. When moist, warm air comes into contact with cooler surfaces, small droplets of water immediately appear. Poor ventilation in places with high humidity, such as in boiler rooms, kitchens and bathrooms, is the most frequent reason for condensation.

To lower the impact of this issue there are a couple of simple steps that you can take. You can wipe away any droplets the instant they appear, and you can make certain that there's good ventilation in areas that suffer most from condensation. The steps needed may require the upgrading or installation of cooker hoods, extractor fans and air bricks, with the purpose of redirecting humid air outside of your home in Portland.

The most effective way to identify the key factors that play a role in the situation, is to have an in-depth damp proofing survey carried out by an experienced Portland company. Occasionally moist air is drawn in from the outside, simply making things even worse. The best way to adequately control condensation is to regulate airflow correctly, and your local Portland damp proofing company will be able to give you advice and guidance on how this can best be achieved.

Damp Proofing Quotes in Portland Dorset


A damp proof course or membrane has been compulsory on houses constructed in the UK since 1875. You might not have a damp proof course on your home or property in Portland if it was constructed prior to this period. It is a possibility that your damp proof course may have been damaged somehow if you are experiencing rising damp issues in a property built after this year.

Rising damp can be difficult to distinguish, but some things to keep an eye out for are; white powdery deposits forming on walls or being discovered on floor surfaces, "tide marks" on walls and rotten or crumbling skirtings. If you see or think that you might have any of these, it's possible you have a problem with rising damp.

Rising Damp Portland Dorset

Remedying rising damp problems can be as simple as checking your external walls to see if you can see a damp course. To be sure of an adequate measure of protection the damp proof membrane needs to be above ground level by no less than 150 millimetres (around 6"). If this isn't the situation you can dig away the ground to create this space, or if this isn't plausible, you could put in a damp course higher up.

If this is not the root cause of the problem and your damp course is in fact correct, there may be more serious issues to resolve caused by the dampness coming up from the ground, up through your floors, and into your walls.

Damp proofing specialists in Portland can swiftly identify and resolve rising damp issues using a range of procedures. A damp proof cream (such as Permaguard) can be carefully injected into your walls if you've got a somewhat older home with no damp proof membrane, or one that is damaged over an extensive area. This special cream is injected with a nozzle into holes drilled at intervals along the mortar joint, and before the cream cures it turns into liquid and soaks into the surrounding brickwork creating a barrier that is repellent to water.

If the damage to the DPM is too extensive, or if damp proofing injection cream isn't an appropriate solution, you may need to put in a new damp proof course. While this level of repair work is a fairly drastic way to solve rising damp problems, it may be your only solution at the end of the day.

Yet another option for less severe areas of membrane damage might include painting with a bitumen based, waterproof latex emulsion. Wood flooring, tiles or carpeting will need to be lifted prior to work being undertaken, since it's applied underneath your existing floor coverings. In basement areas this is a particularly effectual solution, and will form a part of the "tanking" procedure that is used to make spaces watertight. For extra protection in such troublesome areas, your Portland damp proofing specialist might recommend the application of building paper (a specialist foil backed membrane) before the bitumen coating has completely dried out.

Tanking: Tanking a room, like a basement or cellar, is the process of coating any exposed surfaces in a waterproof paint. This has to be applied at the base level of floors and walls, therefore all plaster and wall coverings must be removed and the surfaces in question properly prepared before the commencement of any work. When this paint has been applied, it must be allowed to dry out thoroughly before replastering and decorating over the top of it. You should invariably get more than one expert's opinion about whether this really is the only resolution to your damp problems, because this is a very disruptive process because it has to be applied to an entire basement level or ground floor of a building.


Dehumidifiers are an effective way of reducing the moisture content in the air, so for condensation problems they can help. The fact that these products only mask the cause of the damp and don't get rid of it, is the main issue with dehumidifier use. A reliable damp proofing specialist in Portland will be glad to offer advice on possible solutions if you're suffering from damp or mould in any part of your house.


As with just about any home improvement project, the best recommendations for a local specialist come from friends and relations. Where possible you should try to obtain at least two or three different quotes from a variety of companies, and before signing up for any specific damp proof services, you should ask to look at professional membership certificates and qualifications, as proof of their trustworthiness.

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

Membership of the PCA or DPA guarantees your selected damp proofing provider is suitably qualified and has the appropriate experience to carry out a high quality damp proof service. Such memberships also means that there are certain guarantees for any remedial work undertaken.

Dehumidifier Installation Portland

Dehumidifiers are an essential appliance that must be installed to maintain a comfortable and healthy indoor air quality, especially in regions with high humidity levels. For the unit to perform optimally and last long, correct installation is of utmost importance.

Picking a suitable location that is obstruction-free and has a power source nearby is essential before dehumidifier installation. 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.

The next thing to do is to set up the drainage system properly to prevent water damage or overflow. It could require attaching a hose to the unit or connecting the dehumidifier to a drain. For the appliance to operate effectively, regular maintenance such as cleaning or replacing the filter is crucial.

For a successful and safe dehumidifier installation, it's recommended to seek professional help or consult the maker's instructions. A dehumidifier, when properly installed and maintained, can reduce moisture-related problems, enhance indoor air quality, and improve overall comfort in homes or workplaces.

Woodworm Treatment Portland

Woodworm is a common problem that affects a lot of buildings, particularly older properties in Portland. It is caused by the larvae of certain species of beetles that gnaw away at the wood and can cause significant damage over time. Thus, it's essential to take steps to treat and prevent these infestations.

So as to effectively address a woodworm infestation, it's vital to first determine the specific species of beetle responsible for the damage. Given that various types of beetles call for specific approaches to treatment, it is advisable to enlist the services of a qualified woodworm specialist who can perform an in-depth examination and provide advice on the most appropriate strategies to resolution.

One effective woodworm treatment method is the use of insecticides, which can be applied in liquid or gel form. This type of treatment is really effective for small infestations, but might not be suitable for more extreme cases. For larger or more significant infestations, fumigation might be necessary. This involves sealing-off the affected area and releasing a gas into the space to kill off the larvae. Fumigation is a far more invasive treatment option and requires specialist training and equipment, so it's vital to work with a skilled professional.

In order to thwart the possibility of woodworm infestations in the future, it is essential to establish an unsuitable environment for their growth. This can be achieved through the implementation of measures such as ensuring adequate ventilation, regulating humidity levels, and treating any existing woodworm infestations immediately upon discovery. By taking these precautions and adopting a preventative approach, you can effectively reduce the risk of woodworm damage and avoid the costs associated with remediation.

Regular inspections of the building can help identify any infestations of woodworm early on, allowing for timely treatment to minimise damage. In addition, using wood which has been treated with a woodworm repellent can help in preventing future infestations.

Condensation Control

Maintaining a healthy and comfortable indoor environment requires crucial condensation control. Condensation occurs when warm, moisture-laden air comes into contact with colder surfaces, leading to the formation of water droplets. The growth of mould, damage to building materials, and a decline in indoor air quality are possible results of uncontrolled condensation.

Condensation Control Portland

Good ventilation plays a crucial role in controlling condensation by regulating the amount of humidity and promoting air circulation. Additionally, using insulation and double-glazing can help reduce differences in temperature and minimise condensation. The creation of a more pleasant working or living environment is within reach through effective condensation management, preventing potential problems.

Using double-glazed windows and insulation can help to minimise temperature differences and thus reduce condensation. Insulation prevents cold surfaces and moist, warm air from touching each other by acting as a barrier. When the temperature difference is reduced, condensation is less likely to form on surfaces like windows, ceilings and walls. Condensation is further inhibited by double-glazing, which features 2 panes of glass with an insulating layer in between and is effective at maintaining a consistent interior temperature.

Addressing moisture sources directly is another strategy for effective condensation control. Moisture is released into the air by activities such as drying clothes indoors, showering and cooking. Proper ventilation and exhaust fans in kitchens and bathrooms can help to prevent excessive humidity buildup. In areas which are liable to high moisture content, dehumidifiers can help maintain acceptable indoor humidity levels.

Effectively managing condensation can help you prevent potential issues and create a more pleasant working or living environment. The health and well-being of occupants, as well as the structural integrity of buildings, are both safeguarded by a controlled interior environment. Routine maintenance checks, such as checking seals around doors and windows for gaps, can help identify places where condensation might occur. As building science and indoor air quality knowledge advances, new condensation control strategies and techniques emerge, offering even more effective ways to ensure a comfortable and healthy indoor environment. To conclude, insulation, moisture source management, ventilation, and innovative technologies are all vital components of a well-rounded condensation control strategy.

Friends & Family Recommendations

Obtaining recommendations from friends and family members is invariably really helpful when trying to find a professional contractor for your project or undertaking in Portland. To identify someone who's ideal for your needs, and to filter out bad contractors and companies that have lousy levels of performance, person to person referrals are generally the best way to go.

Friends and Family Recommendations for Damp Proofing

Getting feedback from a friend or relative also means that you can get an insight into the reliability and time keeping of the contractor, and if things went awry, what the contractor's attitude was like, and how rapidly were any problems rectified. They should also be in a good position to provide you with information about how the final bill measured up compared to the original quote that was given, specifics which are typically tricky to get from the contractors directly.

At the end of the day, when it comes to advice, your friends and relatives are individuals you know and trust to be truthful and honest. If they are hesitant to talk about a particular contractor or company it's probably due to a poor experience. A lot of people will be more than happy to speak about a decent quality contractor, less inclined to discuss a poor one, and rather than 'slag off' a a far from perfect business they have dealt with previously, they may endorse some alternative company.
