Damp Proofing Portsmouth Hampshire (PO1)


  • Penetrating Damp

  • Condensation

  • Rising Damp


The following paragraphs describe what causes such damp issues in Portsmouth, and the various methods of avoiding and resolving them.


Penetrating damp in structures can be attributable to different external factors for instance: damaged guttering, unsound brickwork, broken or loose roof tiles and cavity wall issues. From within, the causes can be damaged shower trays, burst or leaking pipes and overflowing baths or basins. If left to carry on leaking these factors allow water to soak into the walls and woodwork, which in time lead to flaking or bubbling paintwork, blistered or broken plaster and dark damp patches on walls.

If neglected for an extended period of time, a leaky roof can cause wet rot to occur in the timbers of your roof. Whilst it's fortunate that wet rot does not have an impact on brickwork, in a worst case scenario, you may need to have a new roof if your roof timbers become unsound structurally. If black fungus starts to appear on any woodwork and the roof timbers feel "spongy" to touch, you could have an issue with wet rot.

You should not fret however, since to stop these problems from occurring, a few straightforward steps such as cleaning and checking your gutters and roof for leaks, examining piping for leaks and repointing dodgy brickwork should avoid such issues. A professional Portsmouth damp proof service provider will check these areas in order to help avoid any future problems, as part of fixing your dampness issues.


Condensation Damp Portsmouth UK (023)

Quite simple to spot and a contributing factor to damp in many Portsmouth properties, condensation is very common. When colder surfaces come into contact with warm, humid air, tiny droplets of water form on those surfaces. Poor ventilation in places with high humidity, for example in bathrooms, kitchens and boiler rooms, is the most common reason for condensation.

Basic strategies to prevent condensation involve wiping up any droplets of water as soon as they appear and ensuring you have enough ventilation in the problem areas. This may require the updating or installation of extractor fans, cooker hoods and air bricks to help reroute the humid air outside of the building.

A detailed damp proofing survey by a reputable Portsmouth company may also find areas which exacerbate the issue by drawing in moist air from outside. Airflow has to be regulated properly to adequately control condensation, and a knowledgeable damp proofing technician will give advice and offer solutions on this question.

Damp Proofing Quotes in Portsmouth Hampshire


Homes built since 1875 in the UK have been required to have a damp proof course or membrane to be installed as standard. If your property was built before this period it's perfectly possible that you might not have one installed. If you are experiencing rising damp in a property constructed after this period it might be that your damp proof membrane or course has been somehow or other.

Although difficult to distinguish, white powdery deposits being found on floor surfaces or appearing on walls, crumbling or rotten skirtings and "tide marks" on walls, are all giveaway clues that you might have rising damp. Although the existence of these isn't conclusive, they're all clear indications of rising damp.

Rising Damp Portsmouth Hampshire

Fixing rising damp issues can be as easy as checking your home's 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 space if it is currently not enough, or you could put in a DPM (damp proof membrane) higher up if the first option isn't feasible.

If this isn't the problem and your DPM is correct, there might be more serious issues to deal with caused by the moisture coming up from the ground, through your floors, and into the walls of your property.

Portsmouth damp proofing experts will swiftly be able to establish the causes of your rising damp issues, and using a variety of methods will quickly fix the problem. Older properties which either don't have a DPM at all, or have one which is damaged over a substantial area, can be treated with a damp proofing injection cream. This calls for the drilling of holes at evenly spaced intervals into your brickwork and the cream injected with a special nozzle to plug the gaps behind the brickwork down to beneath ground level.

In situations where damp proofing cream is not a satisfactory remedy, or where your DPM is too extensively damaged, putting in a new damp proof course could be neccessary. This is the most extreme of repair works, but it could be the only resolution to your rising damp.

Painting with a bitumen based, waterproof latex emulsion, is another potential solution for minimal areas of membrane damage. Laminate flooring, tiles or carpeting will have to be lifted prior to work being undertaken, because it's applied underneath your floor coverings. Also used as a part of the "tanking" process to make a space watertight, this is an especially effectual solution in basements. Before the bitumen coating has completely dried, your Portsmouth damp proof specialist may recommend the laying of building paper (a special foil backed membrane), for additional protection.

Tanking: In basements and below ground areas of a property, "tanking" is a process where any surfaces that are exposed are covered in a watertight coating. This has to be applied on the base surface of floors and walls, and so any plaster and wall covering must be removed and the surfaces prepared correctly before any work begins. You can replaster any walls and decorate on top of it, after the coating has thoroughly dried out. You must always get more than one expert's opinion about whether this is really the only treatment for your rising damp, as this is an extremely disruptive process as it needs to be applied to a whole basement level or ground floor of a property.


Dehumidifiers are an effective way of lowering the moisture content in the air, so for issues with condensation they can be of help. Owing to the fact that dehumidifiers merely cover up the cause of the damp and not get rid of it, there are downsides to this solution. A professional damp proofing company in Portsmouth will be ready to give you advice on the best solution if you're suffering from damp in any area of your house.
