Damp Proofing Portsmouth Hampshire (PO1)


  • Penetrating Damp

  • Condensation

  • Rising Damp


In paragraphs that follow, we'll take a look at what leads to such damp problems, and ways that you can go about solving them, and preventing them from occurring in the first place.


Some of the external factors that can cause penetrating damp in a structure include: damaged guttering or drainpipes, porous brickwork, cavity wall problems and cracked or loose roof tiles. In the interior of your property it can be a result of overflowing baths or sinks, cracked shower trays and leaky or burst water pipes. If left uncontrolled, peeling or bubbling paintwork, blistered or broken plaster and damp, dark patches on walls, will be the visible upshot of water soaking into the walls and woodwork.

If you've got a leaky roof and it has been neglected for some time, it can cause wet rot to develop in the timbers of your roof. Wet rot cannot spread into brickwork, but it can mean that in the worst case your roof timbers become structurally unsound, requiring a new roof. If any of the timbers on your roof feel "spongy" to the touch, and a black fungus forms on the wood, you may have a case of wet rot in your roof.

Preventative measures can be fairly basic, such as examining pipework for leaks, repointing unsound brickwork and cleaning and checking your rain gutters & roof for leaks. If you get hold of a reliable damp proofing specialist in Portsmouth, they'll check all these things, and prepare a plan for both dealing with your dampness problems and forestalling further episodes.


Condensation Damp Portsmouth UK (023)

A common form of damp in Portsmouth properties, condensation is very easy to identify. Water collects as tiny droplets on a cool surface, when moist, warm air comes into contact with it. Condensation is frequently found in areas with poor ventilation and high humidity, such as in bathrooms, kitchens and boiler rooms.

There are a couple of simple ways of addressing condensation issues, and these are making certain that the worst affected areas have adequate ventilation, and wiping droplets of water away as they appear on surfaces. You can reduce the amount of moist air which is present in your building by updating or fitting cooker hoods, air bricks and extractor fans.

There could possibly be issues with drawing in damp air from the outside, and by conducting an in-depth damp proofing survey an expert in Portsmouth will be able to identify factors that give rise to the problem. The most effective way to adequately control condensation is to correctly regulate airflow and circulation, and your local Portsmouth damp proofing company will offer guidance and advice on how this can be accomplished.

Damp Proofing Quotes in Portsmouth Hampshire


Homes built since 1875 in Great Britain have required a damp proof course to be installed as standard. It is perfectly possible that you may not have one fitted if your house in Portsmouth was constructed before this time. If your house was built after this year, but you are still suffering with rising damp problems, it could be that your damp proof course has been impaired.

Rising damp can be rather difficult to distinguish, but some areas to keep an eye out for are; rotten or crumbling skirting boards, "tide marks" on walls and white powdery deposits appearing on walls or being discovered on floor surfaces. It is plausible that you might have a rising damp problem if you have noticed one or more of these.

Rising Damp Portsmouth Hampshire

Fixing rising damp issues can be as simple as checking your outside walls and seeing if you can spot a damp course. It ought to be 150 millimetres above ground level for adequate protection. You could dig away the surrounding ground to create this gap if it is currently not enough, or you could put in a DPM higher up if the former is not plausible.

You could have more problematic issues if you find that your damp proof course is fine, and it could be that the damp is creeping up from the ground, through your flooring, and into your home's walls, which will be even more of a concern.

Damp proofing specialists in Portsmouth will quickly identify and eliminate rising damp problems using a variety of techniques. Older houses which either don't have a damp proof course, or have a compromised one that is damaged over an extensive area, can be treated with a damp proof injection cream such as Permaguard. This entails drilling holes at evenly spaced intervals along the wall's mortar joint and the cream injected with a special nozzle to fill the spaces behind the brickwork.

If the damage to your DPM is too extensive, or if damp proofing cream injection is not a suitable solution, you might have to put in a brand new damp proof course. Although this is naturally a fairly drastic plan of action, it might be the only method to resolve your damp problems effectively.

For less severe areas of damage, another possible option would be to coat with a bitumen based, waterproof latex emulsion paint. Wooden flooring, carpeting or tiles will have to be lifted prior to work being carried out, since it's applied under your existing floor coverings. In cellar areas this is a particularly effective treatment, and will form part of the tanking process that's used to make rooms watertight. Before the bitumen paint has has dried out completely, your Portsmouth damp proofing expert may suggest the laying of building paper (a specialist foil backed membrane), for additional protection.

Tanking: Tanking an area, such as a cellar or basement, is the process of coating exposed surfaces in a watertight paint. This has to be applied on the base surface of floors and walls, so all wall coverings and plaster must be removed and the relevant surfaces prepared correctly before the commencement of any work. You can replaster and decorate on top of it, as soon as the coating has completely dried out. Since it needs to be applied to a whole basement level or ground floor of a property, this is a really disruptive job. It is therefore preferable to seek the advice of at least 2 or 3 damp proofing experts to make certain that this is really the only possible option.


Dehumidifiers are a highly effective way to remove moisture from the air, hence for condensation issues they can be of help. The main problem with dehumidifier use in trying to stop damp is that they only alleviate the cause of the damp, don't cure it. A reliable damp proofing specialist in Portsmouth will be glad to give you advice on the best solution if you're suffering from mould or damp in any part of your property.
