How to prevent condensation in your home

How to prevent condensation in home

Table of Contents

Condensation is a common problem in UK homes, especially during the colder months when we fire up the central heating! Moisture in the air is perfectly normal, but when warm, moist air comes into contact with cold surfaces such as windows, roofs and even furniture it condenses, leaving droplets which can lead to a whole host of issues, including damp, mould growth, nasty smells and even cause respiratory problems.


You would think that new ultra-modern homes would be less likely to have damp, but it’s actually pretty common in new builds too, due to moisture gathering during the construction phase and insufficient ventilation. While new builds tend to have very efficient insulation, if the ventilation in a home is not up to scratch it will create a breeding ground for condensation problems.


There are several steps you can take to reduce condensation and prevent it from causing serious problems.


Prevention Strategies


Reduce Moisture Production:

Use lids on pans when cooking

Avoid drying clothes indoors, particularly on radiators


Improve Ventilation:

Ventilate your home regularly, especially after cooking, showering, or bathing

Use an extractor fan in the kitchen and bathroom

If you have to dry clothes indoors try using a dehumidifier

Open windows and doors whenever possible

Ensure your windows and doors have trickle vents (This has been mandatory on new windows and doors since June ‘22) 

Keep air vents clear

Consider installing a whole-house ventilation system


Increase Insulation:

Insulate your loft and cavity walls.

Install double glazing.

Draughtproof your home.


Maintain Proper Heating:

Heat your home to a consistent temperature.

Avoid over-heating

Use a dehumidifier if necessary


Additional Tips

Wipe away condensation as soon as possible to prevent mould growth, being sure to check poorly ventilated areas such as behind large furniture, and around any openings in your home such as windows and doors.

Use mould-resistant paint in areas prone to condensation

Regularly inspect your home for signs of dampness or mould


Addressing Existing Condensation Problems

Identify the source of the moisture and take steps to eliminate it

Repair any leaks or water damage

Dry out affected areas thoroughly

Use a dehumidifier to remove excess moisture from the air



Condensation may be a common problem in UK homes, but it doesn’t have to be a major one. By following the tips outlined in this blog, you can reduce condensation and create a healthier, more comfortable living environment.
