In the following paragraphs, we will look at what causes such damp problems, and how you can go about fixing them, and stopping them from happening in the first place.

PENETRATING DAMP

There are various external factors that can lead to penetrating damp in a property, and these include such things as: porous brickwork, blocked cavities, loose or broken roof tiles and damaged downpipes or guttering. Inside your Welwyn Garden City property, it can be the result of cracked shower trays, burst or dripping pipes and overflowing basins or bathtubs. If water continues to seep into the walls and woodwork, the noticeable signs with time are going to be dark, damp patches on walls, broken or blistered plaster and peeling paintwork.

If left untreated over a period of time, a leaky roof can cause wet rot in the timbers of your roof. Despite the fact that bricks and brickwork are not impacted by wet rot, the timbers on your roof can suffer serious consequences, and if it becomes structurally unsound, the whole roof may have to be replaced. There are various warning signs of wet rot that aren't hard to spot, the principle ones being; a musty smell, the appearance of black fungus on woodwork and a "spongy" feel to the timbers. 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 steps like cleaning your roof & rain gutters and checking for leaks, inspecting pipework for leaks and repointing brickwork, are the basic preventative measures. A professional Welwyn Garden City damp proof service provider will check these areas to help prevent any future problems, as an integral part of fixing your issues with damp.

CONDENSATION

Condensation Damp Welwyn Garden City UK (01707)

One of the most common forms of damp in Welwyn Garden City properties, condensation is super easy to identify. When a cold surface makes contact with warm, moist air, water collects as small droplets upon that surface. Inadequate ventilation in places with a high level of humidity, for example in boiler rooms, kitchens and bathrooms, is the most common reason behind condensation.

Easy strategies to stop condensation include wiping up any water droplets whenever they appear and making certain you've got adequate ventilation in the problem areas. You can reduce the volume of moisture laden air which is present in your house by updating or fitting extractor fans, cooker hoods and air bricks.

A damp proofing survey from a reputable Welwyn Garden City company might also find factors which play a role in the problem by drawing in moist air from outside. An expert in this industry will be able to provide solutions, information and guidance on this matter, because for condensation issues to be controlled, airflow and circulation within the home must be regulated correctly.

RISING DAMP

Houses built since 1875 in the United Kingdom have required a damp proof course to be fitted as standard. It is quite possible that you may not have one fitted if your home in Welwyn Garden City was built before this time. If you are suffering with rising damp in a home built after this time it might be that your damp proof course or damp proof membrane has been damaged somehow.

If you suppose that you might have rising damp, crumbling or rotten skirting boards, white powdery deposits being discovered on floor surfaces or appearing on walls and "tide marks" on walls, are good indications that you might be right. It's plausible that you may have a rising damp issue if you have seen one or all of these.

Rising Damp Welwyn Garden City Hertfordshire

The initial step towards handling your rising damp should be to simply check whether or not you have a damp proof course on the external walls of your home in Welwyn Garden City. It ought to be 150 millimetres (approximately 6") above the level of the ground for satisfactory protection. You could dig away the surrounding soil to generate this space if it's currently not enough, or you could put in a higher DPM (damp proof membrane) if the first option is not plausible.

If this is not the root cause of the problem and your damp course is installed and in order, there could be more serious issues to resolve caused by the dampness coming up from the ground, through your floors, and into your walls.

Welwyn Garden City damp proofing experts will quickly be able to establish the cause of your rising damp issues, and using a range of techniques will soon resolve the problem. A damp proof cream (such as Permaguard or Dryzone) can be carefully injected into your walls if you've got an older home with no damp proof course, or one that is damaged over a substantial area. This entails the drilling of holes at intervals in your brickwork and the special cream injected with a nozzle to plug the spaces behind the brickwork down to beneath ground level.

In instances where damp proofing injection cream isn't a satisfactory treatment, or where your damp course membrane is severely damaged, putting in a new damp proof course may be neccessary. This is taking repair work to the extreme, but it may be the only resolution to your rising damp.

For smaller areas of membrane damage, another potential solution could be to coat with a bitumen based, waterproof latex emulsion paint. This will be applied underneath your current floor coverings, so carpeting, tiles and wood flooring must be lifted before any work can be undertaken. In basement areas this is a particularly efficacious solution, and will form part of the "tanking" procedure which is used to make spaces watertight. Your Welwyn Garden City damp proof expert might advise a layer of building paper (a foil backed specialist membrane) before the bitumen paint has completely dried out, extra protection in these problem areas.

Tanking: The practice known as "tanking" is a specific waterproofing method for basements, cellars and other underground areas. This method involves applying a specially formulated waterproof paint directly onto bare surfaces. For this to be effective, all existing plaster and wall coverings must be removed, ensuring the coating is applied at the very base of walls and floors to create a watertight barrier. After application, the coating needs thorough drying before any wall replastering or decorative works can commence. Tanking is an extensive procedure, involving the treatment of the entire lower area of a property. Thus, it's prudent to seek opinions from multiple damp proofing professionals to determine whether tanking is indeed the best approach for your particular rising damp problems or if there are other less invasive but equally effective methods.

SOLVING DAMP PROBLEMS WITH DEHUMIDIFIERS

To help ease condensation issues, you could try using dehumidifiers, which for removing moisture from the air, are really efficacious. Because dehumidifiers simply alleviate the cause of the damp and don't cure it, there are downsides to this option. If you are suffering with dampness in any area of your property in Welwyn Garden City, you should contact an experienced damp proofing company for the best advice.

Benefits of Using Dehumidifiers

Presented below are some positive aspects of dehumidifier usage:

  2. Comfort: Occupants' living conditions are improved through the decrease in humidity levels, making the indoor space feel more comfortable and cooler.
  3. Energy Efficiency: Potential savings on the use of energy are a benefit of using certain dehumidifiers, as they aid in making air drier and consequently easier for heating systems to heat efficiently.
  4. Protects Belongings and Property Structure: Damp-related issues are averted and belongings are protected from moisture damage when humidity levels are kept low, safeguarding the building's structural soundness.
  5. Reduced Odours: Leads to a fresher, more agreeable living environment by removing the musty odours linked with high levels of humidity.

PIV (Positive Input Ventilation)

Positive Input Ventilation (PIV) can offer the perfect solution to reduce damp problems within your property in Welwyn Garden City. If you have noticed mould and damp inside your home or condensation around the windows then PIV can help to reduce the humidity. To achieve this, a constant flow of fresh air is supplied.

Woodworm Treatment and Prevention

Unfortunately, woodworm is a common problem that can affect properties of any age. The larvae of certain kinds of beetles feed on the timber, which can lead to substantial damage over time. Nonetheless, there are a number of steps that you can take to prevent woodworm infestations in the future and address any current problems.

The first step in woodworm treatment is to determine the type of beetle that's causing the problem, as different types require different treatments. A woodworm specialist can carry out a thorough inspection to determine the degree of the infestation and recommend the best course of action.

One effective woodworm treatment technique is the use of insecticides, which can be applied in liquid or gel form. This type of treatment is really effective for modest infestations, but might not be suitable for more severe cases. For larger or more severe infestations, fumigation might be necessary. This involves sealing the affected area and releasing a gas into the space to kill off the larvae. Fumigation is a much more invasive treatment option and calls for specialist training and equipment, so it's vital to call in a qualified professional.

Prevention is also key in avoiding future woodworm infestations. This can be achieved through regular inspections, maintaining good ventilation and humidity levels, and treating any existing woodworm as soon as it's identified.

Frequent inspections of the building can also help identify any woodworm infestations early on, allowing for timely treatment to minimise damage. It's also important to address any water damage, as damp wood can attract woodworm.

Dehumidifier Installation

Dehumidifiers are an essential appliance that must be installed to maintain a healthy and comfortable indoor air quality, especially in regions with high humidity levels. Correct installation is crucial for the optimal longevity and performance of the unit.

Picking a suitable location that is obstruction-free and has a power source nearby is essential before dehumidifier installation. It's essential to ensure that the unit is placed on a flat surface and kept away from walls and furniture to allow for sufficient air circulation.

Correct setup of the drainage system is necessary next to avoid water damage or overflow. Attaching a hose to the unit or connecting the dehumidifier to a drain may be essential for the process. Routine maintenance, such as cleaning or replacing the filter, is essential to ensure the dehumidifier operates effectively.

Selecting the appropriate size and location for a dehumidifier can lead to significant improvements in its benefits and performance. It's recommended to refer to the manufacturer's instructions or seek professional assistance to ensure a safe and successful dehumidifier installation. Proper installation and maintenance of a dehumidifier can lead to reduced moisture-related issues, improved indoor air quality, and enhanced overall comfort in homes or workplaces.

Cementitious Tanking

The favoured solution for preventing the ingress of water in cellars and underground spaces is cementitious tanking. This process involves the application of a cement-based water-resistant system to the floors and walls of the space or room. Available in a range of grades suitable for various substrates, the tanking material can be pre-manufactured or mixed on-site.

Cementitious Tanking Welwyn Garden City

A durable and long-lasting barrier against water penetration can be achieved through correct application of cementitious tanking for maximum effectiveness. For optimal results, the surface must be free from any loose material or contaminants and must be dry and clean before application.

This intricate process typically requires the expertise of seasoned professionals, as it hinges on meticulousness and precision to guarantee an impenetrable seal against moisture intrusion.
