Are you suffering damp in your home? Maybe noticed some of the obvious signs of damp peeling wallpaper, mould  on your walls, or a musty smell?  Damp Protection Services provide damp solutions for your home, from chemical injections and waterproofing, to an installation of a damp proofing membrane.

There are many signs of rising damp, peeling wallpaper and mould growth are obvious indicators, however you might also notice rot in timber, wet skirting boards or damp looking exterior brick or stonework. If you notice any of these signs of damp contact Damp protection services for a damp survey.

Damp Protection Services provide a number of options to help you overcome your damp issues. First, we'll begin with a site survey to find the source of the damp. Then we provide a full program of works and possible treatments of rising or penetrating damp issues.

Damp in a domestic property is usually caused by one or more of three main issues:

  1. rising damp
  2. penetrating damp, or
  3. ventilation issues (condensation).


Damp Protection Services are happy to give advice on any of these issues affecting your home.

Rising Damp

Rising damp is usually slow to develop and can be seasonaly effected, increasing in and falling in summerand can be present for several years until symptons develop. Rising damp may show as a tide like damp patch or stain on the wall while above shows little or no damage, below the paint may be bubbling or blistering, wall coverings may be  stained and peeling, plaster damaged and skirting boards showing signs of dry rot or timber decay. Externaly the signs of rising damp are white salt marks or darkening of the lower brickwork and even spalled (damaged) bricks. Floors show moist patches and damp staining.

Seasonal effects shouldt be taken into account in any diagnosis since the damp issues can disappear in the summer months and return in the winter.

Rising damp is described as dampness resulting from upward movement of water in the ground rising  through the foundations by capillary action. This usually occurs at ground floor level  of external and interior partition structual walls. The height to which rising damp will rise dependson the amount of moisture in the ground and the evaporation rate from the face of the wall surface. As a g Salting is normally present in the plaster on the walls suffering from rising damp. These salts will also absorb moisture from the air making the walls evem more damp. This is the main reason plaster I has to be removed from any wall suffering from rising damp , the height of rising damp usually is not much higher than 1 metre above ground level.

However, the presence of a damp proof course does not guarantee that rising damp will not occur.  If the continuous run of the dpc has been bridged or broken then dampness can appear.

Rising Damp Survey

Before choosing which installation of a chemical damp-proof course to cure the effects of rising damp, the Damp Protection Services specialist surveyor will have to carry out a damp survey to assess the damp issues  and attain the exact cause of the damp issues to establish the need and sutability for rising damp treatment and protection.

There are many factors to be taken into consideration which are all written into the Damp Protection Services survay.  Should the Damp Protection Services surveyor, after carrying out a thorough and exect inspection both  externally and internally, after eliminating all other causes such as penetrating and condensation damp, diagnose rising damp, then we will assess the extent of the dampness and the need for plastering and method.  A damp report/quotation will be provided outlining the most cost effective solution and  remedial treatment to the damp issues at your property. There is usually a small charge for this survay but is usually wavered upon instruction of the works from yourselves.  Allthough we do supply survays only at a cost of £75.00 and will satisfy the mortgage loan providers, estate agents and all other major lenders.

Rising damp treatment in brief:

  • The removal of all salt contaminated and damaged plaster, usually to a hight of 1 metre. Visibly unaffected plaster may be left above the 1 metre level.
  • An application of an anti-sulphate liquid to make salting insoluble prior to plastering injecting a chemical damp-proof course (DPC) to control rising dampness involves the drilling of the mortar both externaly and internaly and then injecting the damp-proof course cream.
  • The installation of a chemical damp-proof barrier course in a house provides an impermeable damp proof course at low to prevent further rising damp issues accuring. This is probably the most effective and common form of damp-proofing treatment used by Damp Protection Services when controlling rising damp in many homes and is considered to be the most cost effective method of rising damp prevention.


Damp Protection Services make sure we do the job right we then seal with a damp proofing membrane or a tanking slurry. Damp Protection Services feel this is an excellent and most appropriate course of action and gives you the home owner full piece of mind as it gives double the protection.
                                                                                            
Walls are then re-boarded and re-plastered. Where existing plaster isn't thick enough to make boarding out practical a render coat is applied to the walls prior to re-plastering.
