Damp & Mould Specialists in London

Local damp and mould specialists covering London

London’s older housing — particularly its Victorian and Edwardian terraces and converted flats — is prone to rising damp, penetrating damp and, very commonly, condensation and the black mould that follows. London damp specialists focus on diagnosing the real cause first, because solid-wall period homes and poorly ventilated flats each need a different approach.

With so many rented homes in the capital, landlords increasingly need prompt damp and mould surveys and treatment to keep properties safe and compliant.

Tackling damp in London’s older housing

A large share of London’s housing is solid-wall Victorian and Edwardian property built long before modern damp-proofing, which is why damp problems are so common across the capital. There are three main culprits, and they are often confused. Rising damp comes up from the ground where a damp-proof course has failed or was never fitted; penetrating damp finds its way in through walls, roofs or around windows; and condensation — by far the most common in flats — forms when warm, moist air meets cold surfaces in poorly ventilated rooms.

The right fix depends entirely on the cause, so a good damp specialist starts with a proper survey and diagnosis rather than an instant quote for one blanket treatment. Treating condensation as if it were rising damp, for example, wastes money and leaves the real problem untouched. Solutions range from installing or replacing a damp-proof course and tanking cellars to repairing external defects and, very often, simply improving ventilation and heating.

Because damp work is easy to oversell, it pays to choose a specialist affiliated with the Property Care Association (PCA) and to get a clear written report explaining what was found and why the recommended work is needed. Where damp has caused timber decay or woodworm, treatment and replastering may also form part of the job.
