Damp Proofing Quotes in Penryn Cornwall


Ever since 1875, a damp proof course or membrane has been compulsory in all homes built in Great Britain. It is possible that you may not have one fitted if your home in Penryn was built before this year. If your home was built after this date, but you are still experiencing rising damp, it might be that your damp proof course has been compromised.

It can be hard to identify rising damp, however some giveaway indications are; tide marks on walls, rotten or crumbling skirting boards and a white powdery deposit being found on floor surfaces or forming on walls. It's feasible that you may have a rising damp issue if you have noticed one or more of these in your home.

Rising Damp Penryn Cornwall

Simply checking your property's exterior walls to find out if you've got a damp course can be one step towards eliminating your rising damp. For satisfactory protection it ought to be 150 millimetres (about six inches) above the level of the ground. If this is not the situation you can dig away the ground to create this space, or if this is not plausible, you could install a higher damp proof membrane.

If this is not the cause of the problem and your DPM is correct, there may be more problematic issues to resolve caused by the dampness coming up from the ground beneath, through your floors, and into the walls of your home.

Damp proofing experts in Penryn can swiftly detect and remedy rising damp using a range of procedures. Older homes which either have no damp proof course, or have one that is damaged over a significant area, can be treated with a damp proofing injection cream such as Permaguard. This cream is injected with a special nozzle into holes drilled at intervals along the mortar joint, and before the cream sets it diffuses into the adjoining brickwork forming a barrier that is water-repellent.

If the damp proof cream treatment isn't suitable, or the damage is too extensive to your DPM, a new damp proof course might need to be put in. Though this is of course a fairly extreme plan of action, it may be the only way to resolve your rising damp issues in an effective way.

Another possible option for less severe areas of damp course damage might include painting on a layer a waterproof (bitumen based) latex emulsion. This will be applied underneath your current floor coverings, so tiles, carpets and laminate flooring will need to be lifted prior to work being undertaken. In basements this is an especially effective treatment, and will form a part of the "tanking" process that is used to make rooms watertight. Before the bitumen coating has completely dried, your Penryn damp proofing specialist may suggest laying building paper (a special foil backed membrane), for additional protection.

Tanking: Tanking a room, such as a basement or cellar, is the process of covering exposed surfaces with a waterproof paint. This should be applied at the base level of walls and floors, and so any plaster and wall covering must be removed and the pertinent surfaces prepared correctly before the commencement of any work. As soon as the coating has been applied and is dry, it's then possible to replaster the walls and decorate over the top of it. This is a highly disruptive process since it needs to be applied to an entire ground floor or basement level of a building, and it is wise to get more than one specialist opinion about whether this is really the only treatment for your rising damp.


Problems with condensation can certainly be helped by the use of dehumidifiers, which are a highly effective way of reducing the moisture content in the air. The disadvantage with dehumidifiers in seeking to eliminate damp is that they just cover up the cause of the damp, not get rid of it. If you are suffering with damp or mould in any part of your property in Penryn, you can get in touch with a certified damp proofing specialist for the most reliable advice.


Friends and neighbours should always be your first choice when you are looking for recommendations for local professionals.

If left untreated, woodworm can cause a lot of damage and compromise the structural integrity of buildings. Thankfully, woodworm treatment options are readily available available in Penryn.

This method is most effective for modest infestations, and a specialist will determine whether this is the best option. For infestations that are more severe, fumigation may be the answer. This involves sealing the affected area and releasing a gas into the space to kill off the woodworm larvae.

Additionally, it's important to avoid using untreated wood, as this is more susceptible to woodworm infestations. Using timber that has been treated with a woodworm repellent can help to prevent future infestations.

All in all, it is necessary to use an established woodworm specialist in Penryn to identify, assess, and treat any infestations to maintain the structural integrity of the building.

If you're looking to reduce damp problems within your house in Penryn, Positive Input Ventilation (PIV) may be the perfect solution. The reduction of humidity through Positive Input Ventilation can be helpful in alleviating damp and mould in your home, or condensation on your windows. It maintains this by constantly supplying a flow of fresh air.

Condensation Control Penryn

Maintaining a pleasant and healthy indoor environment requires crucial condensation control. The formation of water droplets happens as warm, moisture-laden air interacts with cooler surfaces, resulting in condensation. The consequences of uncontrolled condensation include mould growth, damage to building materials, and the deterioration of indoor air quality. To control condensation, adequate ventilation is essential to regulate the level of humidity and promote the circulation of air. To minimise condensation and reduce temperature differentials, consider using insulation and double-glazing. Achieving effective condensation management allows for the prevention of potential issues and the creation of a more pleasant living or working environment.

Temperature differentials and condensation can be reduced and minimised with the help of insulation and double-glazed windows. Cold surfaces and warm, moist air are kept apart by insulation, which serves as a thermal barrier. When the temperature difference is reduced, condensation is less likely to form on surfaces like walls, windows and ceilings. Double-glazing is effective at maintaining an even interior temperature, which inhibits condensation. It features two panes of glass with an insulating layer between. (23095)
