Surveying damp

The surveyor will spend the first part of the assessment checking around the permitter of your home and all of the exterior parts of the house for any issues that may allow dampness to penetrate through the walls.

They will then move onto the inside part of the property, and they will fully assess all of the interior walls, the flooring, and the ceiling for any damp problems.

Types of Damp

There are three main types of damp that can affect the home – condensation, rising damp, and penetrating damp. Below is a list of information about each of these types of damp and how they are treated:

Condensation

Condensation is the most common type of damp problem in UK homes. This type of damp is caused by warm, moist air that condenses on walls that are cooler in temperature.

This type of damp is most common in rooms that naturally generate a lot of moisture in the air, such as a bathroom or kitchen. It most commonly becomes an issue during the winter months when the walls in the home tend to be a cooler temperature. However, it can also become a problem in the summer months.

Central heating can be one of the causes of condensation. This is because central heating gets very warm and then cools down again. This causes warm, damp air that can then lead to condensation. A lack of ventilation in the home can increase the probability of this becoming a problem.

If condensation is left untreated, it can cause your door and window frames to decay and damage the plaster and paint on your walls. If you see condensation forming in your home, you should always aim to wipe it away as soon as possible.

Condensation damp

Below is a list of some of the symptoms of condensation:

  • An unpleasant mouldy smell
  • The appearance of dark mould, particularly around windows or on glass
  • Water droplets appearing on windows and walls
  • Rising Damp

    Rising damp is caused by water on the ground that rises up through a wall or the flooring. Walls naturally allow a small amount of water in; however, this won't usually cause any damp problems. This is because most homes are fitted with a damp-proof-course or damp-proof membrane. Rising damp tends to be most common in older homes that may not have this benefit.

    Rising damp can also be a problem when there is a lack of drainage or when the level of the ground on the outside of your property is higher up than your damp-proof course. This will allow water to get above it and can lead to dampness entering the property.

    rising damp

    Below is a list of the symptoms of rising damp:

  • Damage to skirting boards
  • Paint and wallpaper begins to peel, often with wet patches
  • A white, powdery substance appears on the wall
  • Floor coverings may start to lift
  • Marks that rise up the wall
  • Damage to plastering
  • Penetrating Damp

    This type of damp happens when water leaks through the walls. It can expand across the walls and onto the ceiling. This type of damp is usually caused by structural problems within the building.

    When your home has cracks in the ceilings or walls or if there are any problems with the guttering or roof, this can cause penetrating damp. When your home has structural issues, water can enter through the cracks, or leaks can happen when it rains. Penetrating damp may also be caused by problems such as leaking pipes within the walls.

    Penetrating damp is most common in older homes as new homes are often built with cavities in the wall to provide some protection against this type of damp.

    penetrating damp

    Below is a list of the symptoms of penetrating damp:

  • Damp patches on the ceiling that become darker when it rains
  • Damp patches on the walls become darker when it rains
  • Benefits of a Damp Survey

    There are many benefits of getting a damp survey on your home. Below is a list of the main advantages of this type of work:

    Identify Damp Problems

    If you have a damp survey conducted on your home, you can identify all of the damp issues in and around your home. If you are concerned about your home or the health of those living within your home, then a damp survey can help you identify the level of the damp problem in your home.

    FAQs

    Q: What does a damp survey involve?

    A: The surveyor will spend the first part of the assessment checking around the permitter of your home and all of the exterior parts of the home for any issues that may allow damp to penetrate through the walls.

    They will then move onto the inside part of the property, and they will fully assess all of the interior walls, the flooring, and the ceiling for any damp problems.

    Q: Who pays for a damp survey?

    A: The homeowner is responsible for paying for a damp survey. In some cases, you may be able to get a free damp survey to identify the damp problem in your home. However, these types of surveys do not tend to be very thorough, and some of the issues may be missed.

    For a complete damp survey, it is always best to hire a professional company to complete a full survey of your home to determine the exact cause of the problem so that an appropriate treatment plan can be put in place.

    Q: What are the main signs and symptoms of damp in a home?

    A: There are several common signs of damp in a home. You may notice a strange, musky smell throughout the house, cracked or crumbling plaster, peeling wallpaper, cold or damp walls, cold or damp flooring, cold or damp ceilings, excess condensation on the windows in your home, dark patches appearing on the walls, the presence of mould and mildew.

    If you notice any of these signs or symptoms in your home, then this is a sign that you may have a damp problem, and you should invest in a damp survey to determine the cause so that you can come up with an appropriate treatment plan.

    Q: Do I need a damp survey at my home?

    A: If you see any signs of damp, no matter how small they may be, you should hire a professional as soon as possible to prevent the problem from becoming much worse than it is now.

    If you are a new homeowner or planning on purchasing a new home, then it is recommended that you hire a professional to assess any risks of damp problems beforehand.

    Q: Is damp in the home dangerous?

    A: Small patches of damp in the home are not much of an issue if they are resolved quickly. However, if you leave these small patches to penetrate and spread to other areas of your home, then your home may suffer from some structural damage.

    Damp problems should be resolved as soon as possible to prevent them from spreading. It can cause the plaster on your walls to crack and crumble and may also cause some structural materials to rot. If your damp leads to mould, then your family may be at risk of health problems that are associated with mould.
