How we approach condensation and mould fixes in Downham Market
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. We tell you if that is what we find rather than selling a fan that will not help.
Survey and findings
Humidity and surface readings, existing fans flow-tested, and a written list of causes and fixes.
Fan upgrades
Weak or loft-vented fans replaced and ducted outside, with humidity control.

Questions from Downham Market
How do I get a price for a condensation fix in Downham Market?
Use the guide price tool, the form on this page, live chat, WhatsApp or call 0800 088 6341. A postcode and a couple of photos help us give you a useful answer first time.
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.
