Ventilation & Condensation

What is Ventilation and Condensation?

At No. 1 Home, we’re here to help with issues associated with ventilation and condensation in Bournemouth and the rest of Dorset.

Condensation – Condensation is the result of warm water vapour filled air condensing when it comes into contact with cold surfaces like walls or windows. Upon contact, beads of water (condensation) are left behind on the surface which are the characteristic signs of condensation.

Ventilation – The main cause of condensation is a lack of adequate air ventilation in the property. Modern homes are designed to be as energy efficient however, improvements like double glazing and draught excluders can seal damp air within a property. This allows condensation problems to fester creating a damp, musty, unhealthy environment.

Excessive Moisture – In addition to lack of ventilation, certain unavoidable behaviour contributes to excessive moisture and condensation in the home. Common daily activities such as showering and cooking release humid air into the atmosphere which contribute to condensation.  Moisture and condensation are most prominent in the winter months.

    Combatting Condensation

    What We Do.

    Passive Air Vents (PAVs) – We may recommend installing passive air vents (PAVs), which can expel up to 2.5 litres of water each per day.  Easy to install, maintenance free and environmentally friendly.  They work by allowing damp air out of the building and dry air back in; lowering the moisture in the air.

    Positive Pressure Ventilation System (PPVS) – This provides heated air, filtered to minimise the amount of moisture that builds up inside the property. These systems greatly help to reduce the humidity in your property.

    Anti-Condensation Paint – This specialist water-based emulsion can dramatically reduce the formation of condensation on interior walls and ceilings. Treated surfaces will be more resistant to the build-up of moisture, mould and fungal growth. It helps to alleviate any problems with black mould and damp patches while potentially saving you money on your energy bills.

    Advice – Our experts will equip you with practical tips and advice on how to increase Ventilation and reduce Condensation in your property.

    Our surveyors will provide a free survey of your property. This allows us to ascertain the nature and severity of the issue and gives you the chance to ask any questions you might have.

    We will listen to your requirements and ensure that you don’t receive generic information or a sub-standard service.

    For your complete ease of mind, we will tailor our response to your specific requirements. Our goal is to provide the most effective service for ventilation and condensation in Bournemouth and the rest of Dorset.
