DAMP PROOFING SERVICES

Most common causes of damp in the properties:

Typically there are three main causes of damp in a property rising damp, penetrating damp, and condensation damp.
Rising Damp

Rising Damp

Rising Damp often occurs in properties where there is no damp proof course (DPC) or where the DPC has been damaged or bridged. As a result moisture from the ground rises up a masonry wall by a capillary action.
Penetrating Damp

Penetrating Damp

Penetrating damp can occur at all levels of a building, but is more commonly found higher up. Porous walls, spalled bricks and degraded mortar allows water to permeate through walls from the outside.

Condensation Damp

Condensation Damp

When moist air comes into contact with cold surfaces like walls, windows etc it can cause condensation damp. The air cannot hold the moisture and tiny water drops appear. It can also occur in corners of rooms, inside or behind furniture where the air is still.
Structural Damp

Structural Damp

Occurs when water penetrates due to cracks or structural issues, often related to building movement or construction defects.

Cold Bridging Damp

Cold Bridging Damp

Caused when warm, moist air comes into contact with cold surfaces (cold bridges), leading to localised condensation and potential damp patches.

Basement Damp

Basement Damp

Occurs when moisture seeps into below-ground areas, such as basements or cellars, due to the surrounding soil's pressure. This type of damp is often caused by inadequate waterproofing or drainage in these areas.

Expert Advice

How Much Does Damp Proofing Cost?

Damp proofing for the property owners can be as little as £150 and starts at about £600 plus vat for the whole house.


ThinkDRY has a conscientious process when injecting a remedial damp proof course to make sure the job is done thoroughly: 


Our local damp proofing technicians will prepare the area that requires treatment both internally and externally before the damp injection begins. This process can involve removing fittings and fixtures such as skirting boards and radiators to provide us the ability to begin the order.


If your property has rising damp then any salt contaminated and damaged plaster will need removed before injecting a damp proof course. 


Our professional damp proofing technicians will drill holes (around 12mm) into the wall mortar joint to a depth of around 10 - 20mm. The damp proof course will then be injected into the boreholes. They are then left in the wall, the injected chemicals will penetrate the masonry surrounding the borehole. Finally the silane gets to work creating a water-repelling barrier, protecting your home from mold and water damage.


After the damp proof injection, our team will re-plaster internally. Our specific re-plastering materials will ensure that any left over salts in the brickwork do not affect the new plaster.

Frequently asked questions

Damp Proofing FAQs

If you have noticed damp patches, mould, peeling paint, damaged plaster or a musty smell in your property, identifying the cause is the first step towards solving the problem. Below, our damp proofing specialists answer some of the most common questions homeowners ask about damp, condensation, rising damp and damp proofing.

  • What is damp proofing?

    Damp proofing is the process of identifying the source of unwanted moisture in a property and applying the correct treatment to prevent further damage. The right solution depends on the cause. Rising damp, penetrating damp, condensation and below-ground water ingress can require very different treatments, so an accurate diagnosis should come before remedial work.
  • How can I tell what type of damp I have?

    The location and pattern of moisture can provide useful clues. Rising damp usually affects the lower part of ground-floor walls, penetrating damp may appear as localised patches that worsen after rain, and condensation commonly affects cold surfaces, windows and corners. These signs are not a definitive diagnosis, so a professional damp survey is the safest way to identify the cause.
  • What are the signs of rising damp?

    Possible signs of rising damp include damp or discoloured areas near the bottom of walls, deteriorating plaster, peeling paint or wallpaper, salt deposits and damaged skirting boards. Similar symptoms can also be caused by leaks, condensation or penetrating damp, so the source of moisture should be confirmed before a damp proof course is recommended.
  • How much does damp proofing cost?

    The cost of damp proofing depends on the cause of the damp, the size of the affected area and the treatment required. ThinkDRY will assess the problem first and provide a clear quotation based on the work your property actually needs.
  • Do you offer free damp surveys?

    Yes. ThinkDRY offers free damp surveys to identify the likely cause of the problem and determine the appropriate treatment. Contact us to arrange a convenient appointment for your property.
