As temperatures drop and the days get colder, many homeowners start to notice damp patches, musty smells and mould appearing around their property. Winter is the season when damp becomes most visible and most disruptive, but understanding why it happens is the first step to fixing it properly.
Why Damp Appears More in Winter
Winter creates the perfect conditions for damp to develop inside a property. Cold external walls, reduced ventilation and higher levels of indoor moisture all combine to create a home that struggles to breathe. Everyday activities such as cooking, showering and drying clothes indoors release large amounts of moisture. When this warm air meets cold surfaces, it condenses, leaving damp patches and encouraging mould growth.
Buildings that already have underlying issues, such as penetrating damp, a failing damp proof course or damp cavity wall insulation, struggle even more during winter. Rainfall increases, walls stay wet for longer, and the cold slows down natural evaporation. As a result, moisture that may have gone unnoticed in summer becomes far more visible in winter.
The Impact on Your Home
Winter damp doesn’t just look unsightly. Persistent moisture can damage plaster, blister paintwork, increase heat loss and create cold, uncomfortable rooms. If damp is caused by moisture trapped inside cavity walls, it can lead to structural concerns such as timber decay or wall tie corrosion. Mould can also develop quickly in winter and spread across walls, skirting boards and windowsills, affecting both your home and your health.
Why a Damp Survey Matters
A damp survey in winter can be one of the most effective ways to understand what’s really happening inside your home. Instead of treating surface symptoms, a survey identifies the exact cause of the moisture, whether it’s condensation, rising damp, penetrating damp or damp insulation within the cavity.
By pinpointing the source, we can recommend the correct repair method, prevent long term damage and stop damp from returning once temperatures rise again.
How CavClear Can Help
At CavClear, we carry out detailed, professional damp surveys designed to get to the root of the problem. We inspect internal symptoms, assess ventilation, check the external structure and, where necessary, investigate the cavity to determine if insulation or moisture build-up is contributing to the issue.
Our aim is simple: to identify the cause of the damp, provide clear recommendations and offer long-lasting solutions tailored to your property.
Don’t Wait for Damp to Get Worse This Winter
If you’ve noticed damp patches, mould, cold rooms or condensation that won’t go away, now is the ideal time to take action. Winter makes damp more visible and that makes it the perfect time to get it properly assessed.
