Preservation Treatments (Surrey) Ltd was established in 1972 and provides Condensation solutions throughout North-West London. If you are in North-West London and are suffering from Condensation then call us on 0800 1422 513 to arrange a survey.


Following our initial instruction one of our qualified surveyors will carry out a detailed inspection and submit a report and quotation together with recommendations.

Increased ventilation and sustained background heating is necessary in avoiding condensation, damp and the effects of black mould occurring. However when windows have to be locked shut, especially during the winter months, a form of automatic ventilation is necessary.

Preservation Treatments offer a great solution for Condensation with our range of positive pressure units. These units replace the damp, stale, air in the property with fresh filtered air. This will not only allow your property to breath but will also eradicate the damaging effects of condensation, damp and toxic black mould.
