Solving Damp Issues Since 1967

Damp is a common problem in homes. Blistering paint, peeling wallpaper, unpleasant smells and mould are often the tell-tale signs and it can be a frustrating problem to manage. Without a damp proofing solution, it can lead to more serious structural damage and can impact the health of those living in the house.

From damaged damp courses, cracked plumbing, condensation and leaking roofs, damp can have many sources, but it can be stopped. The most important thing is to understand the cause of the problem and put damp proofing solutions in place to stop damp in its tracks and prevent it from reoccurring.

At APP Protect, we’ve been providing damp proofing solutions since 1967, protecting thousands of homes across the Cambridgeshire area.

The signs are often more apparent in the winter months when the building itself is colder and windows are opened less.Heating, ventilation or structural insulation issues.Work on ventilation, heating or building insulation and advice on behaviour changes.

The Effects Of Damp

Different types of damp can cause issues in a property, ranging from condensation to penetrating to rising damp. Other specific problems may arise as well, such as wet or dry rot, or even an area requiring a particular treatment like basement damp. Making the right decision can be difficult with so many different types of damp and solutions available. When selecting your own damp proofing method, make sure it is tailored to meet the exact needs of your situation.

What Are The Effects Of Condensation?

Condensation damp is a common problem in homes and buildings, particularly where insulation is poor or ventilation inadequate. The problem can range from occasional build-ups of moisture on windows to more serious issues such as paint peeling off walls or even rot setting in. 

Condensation is caused by warm air containing large amounts of water vapour coming into contact with cold surfaces, usually those outside the property. As the air cools, it can no longer hold as much water vapour and droplets form.

Condensation Solutions

The best way to prevent condensation damp occurring is to ensure that adequate levels of insulation and ventilation are maintained in the building. Insulation helps to prevent warm air cooling down quickly when it reaches cold surfaces, reducing the amount of water vapour that can condense out onto them. Ventilation systems such as extractor fans help reduce moisture in the air within a property and also stop it becoming too humid. It’s important to note that not all ventilation systems are suitable for controlling condensation – an effective system needs both input (fresh air) and output (exhaust air) capabilities.

Quick Condensation Damp Proofing Solutions

In many cases, simple steps like opening windows regularly and keeping them closed during colder weather will be enough to prevent condensation damp occurring, however if your home has persistent problems you should look at installing additional insulation or replacing draughty gaps around windows and doors with better sealants or fittings. In some cases you may need to install a dehumidifier or other specialist equipment, depending upon the extent of dampness present and its exact cause.

Condensation & Regular Maintenance

Remember also that fixing an existing condensation problem may require redecoration or other remedial measures such as brick pointing – so don’t underestimate the importance of regular maintenance work involving normal things like cleaning your gutters or sealing vents around pipework. Keep an eye on any signs of rising damp too; this is often mistaken for condensation but needs totally different treatment approaches to fix effectively!

If you’re having trouble dealing with any kind of damp issue then it’s always wise to get professional advice from a qualified surveyor who knows how they should be dealt with effectively – they can provide tailored solutions based on your specific situation that will work best for long-term prevention against both condensation damp and other types of problems too!

Penetrating Damp Solutions

Penetrating damp is a common form of moisture damage in buildings, caused by water seeping through external walls, roofs and other surfaces due to water leaking in from outside.

This kind of damp can lead to all sorts of problems, from rot setting in and affecting the structural integrity of a building, to mould growth on walls and ceilings – not to mention unsightly staining and discolouration that can be difficult to remove.

Fortunately, there are plenty of solutions available for dealing with penetrating damp effectively. The most important thing is to accurately identify the source of the problem so that you can fix it properly. This could mean blocking up any gaps around windows and doors where water might be entering, as well as checking gutters and downpipes for any blockages that may be causing rainwater to back up against your property’s walls.

Specialist Penetrating Damp Surveyors

In addition, you may also want to consider having a specialist surveyor carry out an inspection in order to assess any underlying issues, such as rising damp that could be contributing towards the problem. Once these issues have been identified then you’ll be able to find an appropriate damp proofing solution. This can include adding a waterproof membrane or installing additional insulation. These actions will help prevent moisture from getting into your property again in the future.

Finally, another key factor when dealing with penetrating damp is proper maintenance: from ensuring your gutters stay free from debris so that they don’t overflow during heavy downpours, to regularly cleaning windowsills and checking for signs of decay inside your property throughout the year. It is vital to look after your home in order to protect it from further damage due to penetrating damp!

The Problems With Rising Damp

Rising damp is the result of moisture from the ground rising up through porous masonry surfaces such as brickwork, mortar and plaster. This form of damp penetration can occur in walls, floors and ceilings, leading to a variety of issues if not addressed quickly.

Unchecked rising damp will cause structural damage to your property. Over time, as dampness increasingly penetrates into subsurface areas, structures become weakened due to moisture saturation. This can lead to wood rot, mould growth and potentially structural damage.


Rising Damp Solutions

It’s important to diagnose rising damp as soon as possible, so that remedial measures can be taken quickly before too much damage has occurred. A qualified surveyor should be able to give an accurate assessment of the extent of the problem and advise on appropriate treatments. Depending on your particular circumstances, these could range from simply providing suitable ventilation or ensuring adequate insulation levels, right through to installing a specialist waterproofing system or replacing sections of wall or flooring entirely.

In some cases, the damp proofing solution may be to install a physical barrier such as a tanking membrane between the property and ground level. This prevents moisture from travelling upwards any further and helps protect the affected area against further damp penetration. It’s worth noting though, that tanking membranes are usually only a temporary solution unless accompanied by other measures, such as improved drainage systems around your property in order for them to stay effective for longer periods.

Rising Damp repair

Finally, once you’ve addressed the issue itself, don’t forget about any damage that has already been done. Professional damp proofing solutions may need to be sought in order to assess and repair any underlying structural problems, such as timber decay caused by previous water ingress.

By combining preventative techniques with repair work you’ll have taken all the steps needed for effectively tackling rising damp once and for all!

If you’re having trouble dealing with any kind of damp issue then it’s always wise to get professional advice from a qualified surveyor who knows how to effectively apply damp proofing solutions. They can provide tailored solutions based on your specific situation that will work best for long-term prevention against both condensation damp and other types of waterproofing problems too.

Do I need a Damp Survey?

If you suspect that there is a persistent damp problem in your home, it’s important to get a professional damp survey carried out as soon as possible. Identifying the source of any moisture and assessing the extent of any damage caused can help to ensure that the most appropriate remedies are implemented quickly and effectively. Effective damp proofing solutions ensure that long-term problems do not arise.

What Does A Damp Survey Involve?

A professional damp survey typically involves an experienced surveyor inspecting all parts of the property, both internally and externally, for signs of water ingress. This usually consists of looking for evidence such as staining on walls or ceilings due to mould growth, as well as checking around windowsills and structural timbers for decay or rot. The surveyor will also be able to advise on the cause of any dampness detected. This could range from issues with inadequate insulation or ventilation throughout a property, through to a more serious issue such as rising or penetrating damp. A robust damp proofing solution will help determine what steps need to be taken in order to resolve it.

Beyond A Normal Damp Survey

In some cases, additional measures such as thermal imaging and intrusive testing may also be required; often this involves drilling small holes into walls in order to extract core samples which are then sent away for analysis. This enables specialists to accurately identify a damp proofing solution and any underlying causes that may have contributed towards the issue in order to provide an effective damp proofing solution.

Once these initial checks have been completed a report will then be issued outlining any areas where remedial action needs to take place in order for them to meet building regulations and become hazard-free again. In some cases further investigations into any potential causes (such as condensation) may also be suggested in order for these issues not only to be resolved but also prevented from occurring again. This could involve a wet rot or dry rot treatment plan.

Is A Damp Survey Worth It?

By having a professional damp survey carried out you’ll have peace of mind knowing that all possible contributors towards your moisture problems have been accounted for – enabling you and your family once more to enjoy living in a safe and healthy property!
