Plastering Specialists

Plastering after damp problems requires specialist techniques and plaster . Standard plasters, such as Carlite, should not be used after a damp treatment as they cannot prevent the migration of hygroscopic salts. Failure to apply a salt retardant plaster after treatment is the most common cause of continuing after a remedial damp proof course has been installed.

Frequently asked questions

What type of tradesman do I need for damp?

You can use several contractors, starting with a damp specilist to identify the cause of the problem and to work out an effective remedy. Then a builder to remove plastering or rotten woodwork. Then a contractor to fit new platster with good quality silicone water-proofer. Then another contractor to fit preventative ventitaltion equipment and so on. Using our services will mean a consistent quality job for one fair price

Is penetrating damp expensive to fix?

Generally roofs will be more expensive than walls or leajking pipes. In terms of damp treatment its always better to find a damp specialist to apply water repellent to the outside of a property

Is a damp proof membrane necessary?

A damp-proof membrane is required when using certain insulation materials. To prevent damp from creeping into the insulation fitting a damp proof barrier is important.

What does a damp proofing specialist do?

Companies like ours that specialise in damp proofing identify the root cause of the damp problem and provide the most appropriate cost effective methods to solve the issue. A survey is required to assess the problem and then to recommend the best course of action.
