We live in Britain – damp, cool climate.
Our buildings are susceptible to damage from damp. Premier Contractors have the personnel and skills to help overcome all forms of damp.

Dampness in buildings causes structural damage to the plaster and fibre of the structure as well as looking unsightly and creating a damp, uncomfortable ambiance.

The decision as to how to combat damp is determined by the cause of dampness. There are, in essence, three types of damp – rising damp, condensation and penetrating damp.

Premier Contractors are experts in identifying all kinds of dampness within a building, and the differences between them. Happily for our clients, we are also expert at dealing with damp when it is discovered.


Premier are experts in every aspect of DAMP proofing

RISING DAMP


Penetrating damp

penetrating_damp_inset_2_360x360

Sometimes called lateral damp is an ingress of moisture penetrating through external walls.
Penetrating Damp is usually due to defects in the building such as faulty rainwater goods, porous brickwork, porous stonework, perished mortar joints, frost damage bricks, and defective or cracked render.

External defects allow moisture to penetrate through the wall and can lead to fungal decay to inbuilt timbers such as Wet Rot or Dry Rot, both extremely hazardous to the health of a building.

Another cause of Penetrating Damp is Porous Brickwork & Stonework allowing moisture through. We are experienced in the uses of a wide range of breathable, external water repellent products which are colourless and applied to the outside of the building.

At Premier Contractors, we have a specialist team who repair external defects before products are applied.

Another cause might be where external ground levels are higher than the internal floor levels. Then, moisture that is naturally in the ground penetrates through the masonry, affecting the internal side of the building. This is also known as bridging and can cause discolouration of paint, peeling wallpaper, damaged plaster or even fungal decay.

Premier Contractors provide alternative barrier solutions such as cavity membranes or cementitious slurries to stop damp penetrating to internal walls.

We offer a comprehensive 10-year guarantee backed by GPI insurance on all our projects.


Condensation

Condensation in the home is a common issue in the UK. However, many people don’t understand that it is reasonably simple to solve and prevent it from coming back.

Premier Contractors have experienced surveyors to diagnose condensation issues. We will give you honest and reliable advice to solve an issue that is often misdiagnosed and treated as rising damp.

As moisture in the atmosphere touches a colder surface, such as warm air meeting a cold window or wall, the warm air condenses. Water is released onto the colder surface, causing tiny droplets to appear.

Condensation can also appear in areas where the air movement is restricted, such as inside wardrobes and behind bedroom furniture, causing a musty smell and leading to mould growth on clothes, furniture and walls.

Typical signs of condensation in your home include:

> Damp patches on walls, especially behind furniture and in corners
> Wallpaper peeling
> Black dots on window reveals
> Streaming windows
> Black spot mould starts to appear
> Damp smell within rooms


rising damp

Rising damp is the effect of moisture rising from the ground into a property’s fabric. The installation of a damp proof course, which may be horizontal or vertical, will prevent rising damp.

Moisture within masonry can cause timbers to become susceptible to risk from fungal decay. This can cause structural damage to the building which can be very costly to repair, especially as most insurance companies do not offer cover for Rising Damp.

After a new damp proof course has been installed, walls which are contaminated with hygroscopic salts also attract condensation. For this reason, Premier Contractors advise that condensation control is just as important as applying Specialist Plastering.

Re-Plastering after remedial treatment for Rising Damp

After a Damp Proof Course has been installed, the affected area will require to be re-plastered using Premier Contractors Specialist Plastering. As the existing plaster work is likely to contain salts that attract moisture from the atmosphere (hygroscopic salts), Premier Contractors Specialist Plastering will control the contamination and stop them coming through to the surface.
