To learn what the likely factors behind such damp problems are, and how you can go about fixing them, carry on reading...


There are numerous exterior issues that can lead to penetrating damp, and included in these are: defective downpipes or guttering, loose or cracked roof tiles, cavity wall problems and damaged or porous brickwork. Inside your St Helens home, penetrating damp can result from leaking or burst pipes, overflowing bathtubs or sinks and cracked shower trays. If water is allowed to continue seeping into the woodwork and walls, the noticeable signs in time will be broken or blistering plaster, peeling or bubbling paintwork and dark, damp patches on walls.

You could get wet rot developing in the timbers on your roof, if you have a leaky roof, and it has been neglected for a while. In the worst case scenario, you might even have to replace the whole roof, since wet rot can cause severe problems with the structural integrity of your roof timbers. If black fungus appears on any woodwork and the timber in your roof feels "spongy" to the touch, you could have the beginnings of wet rot. It is essential to take immediate action if you observe any signs of wet rot to prevent further damage and the possibility of a costly roof replacement.

Simple actions like examining piping for leaks, cleaning and checking your guttering & roof for leaks and repointing brickwork, are the basic preventative maintenance measures. If you use the expert services of a certified St Helens damp proofing provider, they'll check all these elements as part of your all round damp proofing service.


Condensation Damp St Helens UK (01744)

Among the most common reasons for damp is condensation, and numerous properties in St Helens suffer from this. When warm, moist air makes contact with a cold surface, water collects as tiny droplets. Condensation is frequently found in areas with high humidity and poor ventilation, such as in kitchens, bathrooms and boiler rooms.

To minimise the impact of this issue there are two steps that you can follow. You can mop up any water droplets the instant they form, and you can ensure that there is sufficient ventilation in areas that most suffer from condensation. This might call for the installation or updating of cooker hoods, extractor fans and air bricks to help redirect the moist air outside of your house.

By undertaking an in-depth damp proofing survey, an established St Helens company will find any areas where moist air is drawn in from the outside, simply contributing to the condensation issue. So as to manage condensation problems, it is crucial that airflow within the home is regulated properly, and by conferring with an expert in this industry, you will get guidance and advice for resolving these problems.

Damp Proofing Quotes in St Helens Merseyside


Homes built since 1875 in Great Britain have been required to have a damp proof course or membrane to be fitted as standard. You might not have a damp course installed on your home in St Helens if it was constructed prior to this period. It is possible that your damp proof course might have been damaged somehow if you are suffering with rising damp problems in a home built after this year.

Although tricky to distinguish, rotten or crumbling skirtings, white powdery deposits appearing on walls or being discovered on floor surfaces and "tide marks" on walls, are all giveaway signs of rising damp. It is feasible that you could have a rising damp problem if you have spotted one or more of these in your property.

Rising Damp St Helens Merseyside

Merely checking your home's outside walls to spot if you've got a DPM can be one step towards eliminating your rising damp. To be certain of a satisfactory measure of protection the damp proof membrane should be above ground level by a minimum of 150mm (around 6 inches). If you discover this space doesn't exist, you can dig the soil away to increase it, or if this approach isn't plausible, a higher damp proof membrane will have to be put in.

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

Using a variety of procedures, damp proofing professionals in St Helens can swiftly detect and eliminate rising damp. If you've got an older home with no DPM or it is damaged over a substantial area, a damp proofing cream (such as Permaguard or Dryzone) can be carefully injected into your walls. Holes are drilled at intervals in the brickwork, and a nozzle is used to inject the special cream, which then penetrates into the surrounding brickwork before curing to form an effective, horizontal waterproof barrier.

If the damp proofing cream isn't sufficient, or the damage is too extensive to your DPM, a brand new damp proof course might have to be installed. While this sort of repair work is a pretty drastic way to solve damp issues, it could be your only real solution when all is said and done.

Damp Proofing Specialists St Helens (WA11)

For minimal areas of membrane damage, yet another potential option could be to coat with a bitumen based, waterproof latex emulsion paint. This is applied under your current floor coverings, so tiles, laminate flooring and carpeting will need to be lifted before any work is done. This is particularly effectual in cellar areas as an integral part of the "tanking" procedure to create a watertight room. Before the bitumen coating has dried completely, your St Helens damp proof specialist might advise the laying of building paper (a foil backed specialist membrane), for additional protection.

Tanking: Tanking an area, like a basement or cellar, is the process of coating any exposed surfaces in a watertight paint. Because this watertight coating must be applied to the base surface of walls and floors, any wall coverings and plaster must be taken off before any work can commence, and all surfaces properly prepared. As soon as this paint has been applied, it should be permitted to dry thoroughly before replastering the wall surfaces and decorating over the top of it. Since it has to be applied to a whole ground floor or basement level of a property, this is a highly disruptive process. Therefore, it's a good idea to contact more than one damp proofing specialist to be sure that this really is the only possible solution.


Dehumidifiers are an effective way to remove moisture from the air, so for condensation issues they can be of help. The disadvantage with dehumidifier use in endeavouring to prevent mould and damp is that they only cover up the cause of the damp, don't get rid of it. To get the most reliable advice if you're suffering with damp in any part of your property, you should contact an experienced damp proofing specialist in St Helens.


As with just about any home improvement project, the most trustworthy recommendations for a local specialist come from friends and relations. When possible you should always see if you can obtain at least 2 or 3 different estimates from a range of companies, and before employing any particular damp proofing services, you should ask to look at professional memberships and accreditations, as evidence of their credibility.

Professional St Helens damp proofing specialists should be members of either the DPA (Damp Proofing Association) or the Property Care Association (PCA), or have qualifications from the Certificated Surveyor in Remedial Treatments (CSRT) or the CSTDB (Certificated Surveyor of Timber and Dampness).

You can guarantee that your damp proofing provider is suitably qualified and has the necessary working experience to provide a first class damp proof service, if they are members of either the DPA or PCA. Such professional memberships also means that there are certain guarantees for any remedial work completed.
