Damp proofing and timber treatments

Here at Premiere we have solutions to all Damp and Timber problems. All damp work carries a 30 year guarantee and conforms to BS6576.

Rising damp

Rising damp can arise for various reasons: the failure of an existing damp proof course (DPC); bridging due to the raising of external ground or internal floor levels; or in older buildings, the complete absence of a damp proof course.

Brick, stone and mortar are porous, allowing damp from the ground to rise. Where a DPC is absent or inadequate, there are various means of retrospectively fitting one. A common method is to drill holes into the wall at regular intervals and inject a penetrating chemical into the holes. The chemical is absorbed into the mortar bed, where it dries to form a waterproof barrier.

At Premiere we have numerous solutions to problems caused by many forms of damp. Injection externally is the traditional method, or we also have the more modern way using membrane systems for above ground dampness, using tanking membrane internally for party walls and difficult properties i.e. stone-built buildings, barns etc.

Penetrating damp

Penetrating damp is the another common form of dampness in buildings. Dampness occurs in areas as a result of water ingressing horizontally through gaps (sometimes minute) in the building structure. This can be due to wear and tear on pointing in brickwork, leaking roofs and gutters or windows and doors not being sealed correctly.

Other forms of what appears to be dampness in internal buildings are evidence of Black Mould which is always caused by lack of ventilation, creating condensation.


Condensation comes from human activities in the building, e.g. cooking, bathing or drying of clothes on radiators. The moisture in the air condenses on cold surfaces. Buildings with poorly insulated walls are very prone to this problem. It often causes damage similar to damp in a building and often appears in similar places. This is because it occurs in the "dead air" pockets that accumulate in both horizontal and vertical corners (i.e. out of circulating air patterns). The average family of 4.2 creates 15 pints of moisture each day.

Premiere has the solution for condensation problems by using condensation control units. These are the preferred method to disperse any signs of condensation and black mould. Contact us for further information on 0800 542 3982.

Dry & wet rot treatments

Causes of rot are normally due to excessive dampness and lack of ventilation, Normally found to Subfloor Timbers, we at Premiere offer preservative treatments, and timber replacement works.

Insect infestation

The most common being the Wood Boring Weevel and the Common Furniture Beetle. We offer treatment solutions to these problems and many others.
