What the work involves
Ventilation is usually the biggest part of the cure, but not the only part. Heating patterns, insulation gaps and cold bridges matter too, and some damp is not condensation at all: leaks, penetrating damp and rising damp need different trades.
Whole-home ventilation
PIV, continuous extract or MVHR where moisture is spread through the house.
Mould treatment advice
How to clean and treat affected areas once the cause is fixed.

Questions from Enfield Lock
Do you cover Enfield Lock and nearby?
Yes. We cover Enfield Lock and nearby places including Waltham Cross, Waltham Abbey, Ponders End and Cheshunt. Send your postcode and we will confirm.
What is the main cause of condensation in a house?
The main cause is moisture from everyday living, such as showers, cooking and drying clothes, that is not being extracted, combined with cold surfaces where it condenses. Poor or failed extract fans are a very common cause.
Will a dehumidifier fix condensation?
A dehumidifier helps in one room but treats the symptom. Fixing the extract in the wet rooms, and adding whole-home ventilation where needed, removes moisture before it spreads.
