  • Penetrating Damp

  • Condensation

  • Rising Damp


In paragraphs that follow, we'll look at what causes such damp problems, and how you can set about solving them, and stopping them from occurring in the first place.


Penetrating damp in the home can be the result of different external factors for instance: cracks in brickwork, damaged gutters or downpipes, cracked roof tiles and blocked cavities. Inside a structure, leaking or burst pipework, overflowing sinks or baths and cracked shower trays, can lead to penetrating damp. If left unchecked, flaking paintwork, broken or blistered plaster and dark, damp patches on walls, will be the obvious upshot of water seeping into the walls and woodwork.

Wet rot can arise in the timbers of your roof if you've got a leaking roof that's neglected for a while. While it's lucky that wet rot does not have an impact on brickwork, in a worst case scenario, you may need a roof replacement if your roof timbers become structurally unsound. If a black fungus appears on your woodwork and the timber in your roof feels "spongy" to touch, you could have problems with wet rot.

Simple steps like examining pipes for leaks, repointing unsound brickwork and cleaning your guttering & roof and checking for leaks, will be the basic preventative measures. A professional damp proofer in Dereham will check all these areas in order to help prevent any further complications, as an element of solving your issues with damp.


Condensation Damp Dereham UK (01362)

Numerous properties in Dereham suffer from condensation issues, and this is among the most common factors that cause damp. When a cool surface makes contact with warm, moist air, water collects as tiny droplets upon that surface. In places with high humidity, as in: boiler rooms, kitchens and bathrooms, it arises because of poor ventilation.

To lower the impact of this there are two steps that you can follow. You can mop up any droplets of water as soon as they appear, and you can ensure that there is plenty of ventilation in areas that suffer most from condensation. You may need to install or upgrade cooker hoods, extractors and air bricks, so as to remove excess moisture laden air from your home in Dereham.

To find areas which give rise to the issue by sucking in moist air from the outside, a dependable Dereham damp proofing company will carry out a comprehensive damp proofing survey. The best way to adequately control condensation is to regulate circulation and airflow correctly, and your local Dereham damp proofing specialist will offer advice and guidance on how this can be achieved.

Damp Proofing Quotes in Dereham Norfolk


A damp proof course or membrane has been installed as standard on homes built in the UK since 1875. If your property was built before this period it's possible that you may not have one installed. If you're experiencing rising damp in a property built after this time it might be that your DPM has been damaged somehow.

Although tricky to distinguish, crumbling or rotten skirtings, a white powdery deposit forming on walls or being found 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've noticed one or all of these in your property.

Rising Damp Dereham Norfolk

Simply checking your home's exterior walls to find out if you have a damp proof course can be one step towards solving your problems with rising damp. To be sure of a satisfactory measure of protection the damp proof membrane should be above ground level by at least 150 millimetres. You could dig away the surrounding soil to create this gap if it's currently not sufficient, or you could install a higher damp proof membrane if the first option isn't possible.

You might have more problematic issues if you find that your damp proof membrane is okay, and it may be that the dampness is seeping up from the ground, through your flooring, and into your home's walls, which is going to be an even more worrying scenario.

Dereham damp proofing professionals will swiftly be able to determine the causes of your rising damp, and employing a number of procedures will quickly deal with the problem. If you've got an older house with no damp proof membrane or one that's damaged over a significant area, a damp proof cream (such as Dryzone) can be injected into your wall. 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 create an effective waterproof barrier.

If the damp proof cream isn't appropriate, or the damage to your membrane is too extensive, a brand new damp proof course might need to be put in. While this sort of repair work is a pretty extreme way to solve damp issues, it might be the only solution in the end.

Yet another option for less severe areas of damage may include painting on a layer a waterproof (bitumen based) latex emulsion coating. Since this will be applied beneath any existing floor coverings, tiles, laminate flooring and carpeting will need to be lifted before this procedure can begin. This is particularly efficacious in cellars as a part of the tanking procedure to create a watertight room. Your Dereham damp proofing specialist may recommend the use of building paper (a specialist foil backed membrane) before the bitumen coating has completely dried, additional protection in those problem areas.

Tanking: In areas of a house that are below ground, such as cellars, "tanking" is a process where any surfaces that are exposed are painted with a watertight coating. Any plaster and wall covering must be removed and the relevant surfaces properly prepared before work commences, as this watertight coating has to be applied at the base level of floors and walls. As soon as the coating has been put on and dried, it is then possible to replaster and decorate over it. This is an extremely disruptive job since it must be applied to an entire ground floor or basement level of a building, and it is recommended that you get more than one expert opinion about whether this is really the only solution to your rising damp.


To help ease problems with condensation, you could try using dehumidifiers, which for reducing the moisture content of the air, are pretty effective. The disadvantage with dehumidifiers in endeavouring to reduce dampness is that they simply mask the cause of the damp, don't cure it. To obtain the most reliable advice if you're suffering with damp in any area of your home, you can contact an experienced damp proofing company in Dereham.


The best recommendations for specialists when it comes to home improvement projects are generally neighbours and friends. Where possible you should see if you can obtain at least 2 or 3 different quotations from a variety of companies, and before signing up to any particular damp proofing providers, you can ask to look at professional memberships and accreditations, as evidence of their trustworthiness.

Keep an eye out for membership of and qualifications from bodies such as the Damp Proofing Association (DPA) or the PCA (Property Care Association), or contractors holding the Certificated Surveyor in Remedial Treatments (CSRT) or the Certificated Surveyor of Timber and Dampness (CSTDB) accreditations.

Membership of either the DPA or PCA guarantees your selected damp proofing specialist is suitably qualified and has the necessary experience to carry out a top notch damp proof service. Such professional memberships also means there are guarantees for any work accomplished.

Woodworm Treatments in Dereham

Woodworm infestations are not at all uncommon in Dereham, especially in properties that are older where the larvae of certain types of beetles gnaw away at the timber. This can cause significant damage over the years, making the structure unsafe and unsound. Woodworm treatment is crucial to prevent any further harm to the building.

To combat woodworm, the first step is to figure out the exact type of beetle that is causing the damage. As each species of beetle necessitates a unique treatment approach, it's important to bring in a professional woodworm specialist who can perform a thorough evaluation of the situation and prescribe the best course of action. Only with a precise diagnosis and expert guidance can one successfully combat a woodworm infestation.

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

To prevent woodworm infestations, it's vital to make sure that the environment isn't conducive to their growth. This can be accomplished through maintaining correct humidity levels, good ventilation, and treating any existing woodworm as soon as it is identified. Using wood that has been treated with a woodworm repellent can also prevent future infestations.
