Is Condensation Causing Damp & Mould in Your Property?
Streaming windows, damp patches and black mould are signs your building has a condensation problem — not just bad weather. We find the root cause and fix it properly.
Recognise the signs
Does Your Property Have Any of These Problems?
Condensation is the most common cause of damp in UK properties — and it’s frequently misdiagnosed. These are the signs you have a condensation issue rather than rising damp or a leak.
Water on windows
Persistent droplets on glass, especially overnight or first thing in the morning
Black mould on walls
Mould in corners, behind furniture or on external walls — often misread as a leak
Peeling paint or wallpaper
Bubbling or lifting near windows, corners or on cold external walls
Musty smell
A persistent damp odour even after cleaning — often most noticeable in bedrooms or bathrooms
Steamy rooms after use
Kitchens or bathrooms that take a long time to clear after cooking or showering
Damp patches on ceilings
Tide marks or damp spots appearing on ceilings in rooms directly below bathrooms
Our process
How We Diagnose and Fix Condensation
We don’t guess and we don’t recommend solutions before we understand the cause. Every job starts with a proper survey.
Survey
A CSRT-qualified specialist visits to assess moisture levels, airflow and the causes specific to your building
Diagnosis
We identify whether it’s ventilation, heating patterns, occupancy habits, or structural factors — or a combination
Recommendation
A clear, written report with honest options and costs — no unnecessary upselling
Installation
We supply and fit the right solution — from extract fans to full PIV systems — with minimum disruption
What we install
Condensation Control Solutions We Provide
The right solution depends on your property type and the severity of the problem. We’ll recommend the most appropriate and cost-effective option after your survey.
💨 Positive Input Ventilation (PIV)
A whole-house system that gently introduces filtered, drier air from the loft, diluting and displacing moist stale air throughout the property. Suitable for most homes and flats.
🔄 Mechanical Extract Ventilation
Continuous or demand-controlled fans installed in bathrooms and kitchens to remove moist air at source before it migrates to cooler rooms.
🏠 Condensation Control Units
Standalone or ducted units designed for properties where loft installation isn’t possible — including flats, basement conversions and commercial spaces.
🔧 Ventilation System Servicing
Existing ventilation systems need regular maintenance to operate effectively. We service, clean and repair all major types of mechanical ventilation.
Positive Input Ventilation — loft installation
Ceiling extract fan — moisture control at source
Positive pressure ventilation — duct installation
