Discover effective solutions for condensation issues with J.H.
Garlick Ltd. Our expertise in condensation control provides comprehensive strategies to maintain a comfortable and moisture-free environment in your space.


The effects of condensation can be aggravated by modern construction methods and changes to lifestyles. Long term and persistent condensation can result in unsightly black mould and can lead to unhealthy living conditions

Within a building there is always some moisture in the air, with warm air inside the building able to hold more water than cold air.  The higher the temperature of the internal air, the more water vapour it can hold.  When this air becomes cooled it reaches a temperature where it can no longer hold the water vapour, referred to as the ‘dew point’.

There are a number of control measures that can be implemented in order to reduce the likelihood of condensation occurring and further guidance can be provided by ourselves.

Maintaining a reasonable balance between heating, ventilation and insulation can often reduce  condensation issues.

A review of lifestyle and occupation of the property is often helpful.  Regular cleaning away of mould is vital and should be undertaken using a fungicidal wash solution.  Whenever practical, background ventilation levels should be maintained and during periods of colder weather a low level consistent background heating provided.  The use of a de-humidifier should also aid in reducing high atmospheric moisture levels.

Our Surveyors are experienced in advising on condensation issues and correctly identifying issues and we offer a complete service from the application of approved Mould growth inhibitors combined with Thermal wall linings designed and installed to reduce cold bridging at external elevations through to the installation of Passifier vents & mechanical Humidistat controlled extractor fans and heat recovery units.

Passifier vents combine a through the wall warm telescopic sleeve with a louvered vent at each end these type of vents are non-mechanical and take advantage of the difference in the normally higher partial moisture vapour pressure inside an occupied  building than the colder outside.

Humidity vents are suitable for utility areas, kitchens and bathrooms in domestic properties and are seen as a low cost solution, which is ideal for damp or moisture issues that are isolated in one room or area. These fans are easy to maintain and would be installed by experienced and qualified electricians making them ideal for domestic settings.
