What the work involves
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.
Fan upgrades
Weak or loft-vented fans replaced and ducted outside, with humidity control.
Whole-home ventilation
PIV, continuous extract or MVHR where moisture is spread through the house.

Questions from Downpatrick
Is the survey free in Downpatrick?
Visits here are by arrangement. Because of the ferry or long travel involved, we quote travel separately and in writing before you commit, and we can often combine visits to keep the cost down.
Is black mould dangerous?
Damp and mould can affect health, particularly for people with asthma, allergies, weak immune systems, children and older people, according to NHS and government guidance. It should be dealt with rather than lived with.
Is PIV or MVHR better for condensation?
For most existing homes with general condensation, PIV plus good extract fans is the most cost-effective fix. MVHR suits airtight, well-insulated homes and full renovations.
