Dampness at your home can be broken down into three main areas;

  • Rising Damp
  • Penetrating Damp
  • Structural Damp
  • Condensation
Rising Damp

Rising Damp in Derby

Rising Damp occurs in properties when water from the ground rises up through the bricks and mortar of a building by capillary motion, in the same way that a sponge or cloth will absorb water from the carpet.

How do I know if I have Rising Damp?

As a homeowner you can use certain visual and touch signs to help identify rising damp. The normal signals include:

• Wallpaper coming off or peeling from the walls
• Damp patches and discoloration approximately 1 metre up a wall from the flooring
• Tide marks on the wall space up to 1 metre brought on by evaporation and salts from the ground.
• Corroded skirting boards



Penetrating Damp

Penetrating Damp in Derby

Rain penetration (better known as penetrating damp) is a very common form of dampness in homes. It can develop through walls, rooftops or openings such as window reveals. Water will typically enter the exterior envelope of a building and travel indoors.

Typical causes of penetrating damp include:

  • Roof problems such as defective flashing, cracked or missing slates or tiles.
  • Faults in brickwork or masonry, cracked pointing, porous bricks etc.
  • Missing or faulty mastic around doors and windows.
  • To get expert guidance on your how to treat structural damp in your building book a no-obligation survey.

Condensation Control in Derby

Condensation is not just a nuisance, if ignored it can lead to serious problems to the occupants, the home furnishings, the decor and the very structure of a building. Condensation on windows usually leads to faster rot to the lower parts of window casings, condensation on ceilings and walls causes mould and damage to to the plaster, condensation on the undersides of roof surfaces can lead to rot and decay in the loft area. Damp properties will be more expensive to heat and spores from mould can result in medical problems. How to stop condensation is an essential question.

Condensation In Buildings

Condensation in buildings comes from water vapour in the air cooling and precipitating into water in chillier sections of the property or on cold surfaces like windows. All occupied houses will contain water vapour, it comes from our cooking, washing and respiration.

Buildings with poorly insulated walls and poor ventilation are especially prone to this issue. It often results in damage in a building a lot like penetrating or rising damp and it generally would seem in the same places. Condensation is the biggest reason for mould in houses.

How to Stop Condensation

Condensation is normally part of a complex damp house problem and could be the result of various factors. Condensation at the base of external walls is frequently confused with rising damp and costly damp proofing is not going to remedy this problem. The first step is to get expert advice and correctly understand cause and severity of the damp problem, and to help with this our company offers a no-obligation damp survey. One of our certified surveyors will visit your home and provide an independent assessment of the damp problem. We asses the overall damp problem and propose a guaranteed solution including a no-obligation quotation for undertaking the work.
Often the solution is a Dry Air ventilation system.

Structural Damp

Structural Damp in Derby

Structural dampness is the presence of unwanted moisture in the structure of a building. A significant percentage of damp problems in homes are caused by condensation, rain penetration or rising damp.

Effects of Structural Damp

Dampness is likely to do secondary damage to a building. The unwanted moisture enables the growth of a variety of fungi in wood, resulting in rot or mould, these can result in health conditions and will inevitably lead to ‘sick building syndrome’.

Typical effects of structural damp include:

  • Plaster and paint degrade
  • Wallpaper becomes loose
  • Stains from water, salts and mould mark surface areas
  • Concentrations of air-borne mould that once inhaled can lead to serious health effects on people and household pets
  • External mortar and brickwork may crumble
  • Indoor air quality could become very poor which in turn can cause respiratory sickness in residents
  • Excess moisture leads to growth of microbes such as mould, fungi and bacteria which subsequently emit spores, cells and volatile organic compound in to the indoor air.

Woodworm Treatments in Derby

You might not realise that you have a woodworm problem until the resulting damage becomes visible, so early identification is key before they trigger more harm.

Different wood boring insects prefer different kinds of woods, which will help you to determine what type of woodworm is causing your problems. Some prefer softwoods like pine, spruce and cedar while others like hardwoods such as oak, ash, sweet chestnut and mahogany. Whatever the species, each of them will leave several signs, if you have an active woodworm infestation.


There are various tell tale signs that can help you identify woodworm and a potential woodworm infestation. They include:

  • Small spherical exit holes within your woodwork, similar to the holes in a dart board.
  • Fine, powdery dust around these holes (this is called frass).
  • Crumbly edges to boards and joists.
  • Tunnels inside the timber
  • Weak and impaired wood or flooring.
  • Adult woodworm beetles appearing from openings within the timber.
  • Dead beetles near a suspected woodworm infestation or on window sills
