How to Stop Condensation on Windows

Condensation on windows is a common problem for many homeowners, particularly during the colder months. Not only does it look unsightly, but over time it can lead to mould, damp, and even respiratory issues. For homes across Bristol and the South West, the right window solutions can make a huge difference by reducing condensation, improving comfort, and boosting energy efficiency.

What Causes Window Condensation?

Condensation forms when warm, moist air comes into contact with a cold surface, like a window pane. As the air cools, it can no longer hold as much moisture, which collects as water droplets. Older single-glazed windows or poorly insulated frames are particularly prone to this issue because the glass stays colder for longer.

How New Energy-Efficient Windows Reduce Condensation

Upgrading to modern double glazing or triple-glazed windows is one of the most effective ways to tackle condensation. These windows contain multiple glass panes separated by an insulating gap, helping to maintain a warmer internal surface. Features like warm-edge spacer bars and inert gas fills (such as argon) further reduce heat loss. At Crystal Clear Bristol, our energy-rated windows can reduce condensation by up to 70%, improve thermal performance, and reduce CO2 emissions.

Secondary Glazing: A Smart Solution for Existing Windows

For homes where window replacement is not possible, secondary glazing provides an excellent alternative. By adding an extra internal pane, secondary glazing creates a sealed air pocket that acts as a thermal buffer. This reduces the likelihood of condensation forming on the internal surface of the original window.

Secondary glazing also brings additional benefits for Bristol homes, including improved sound insulation, increased security, and enhanced energy efficiency — all without altering the external appearance of your property.

Simple Ways to Minimise Condensation at Home

Even with modern or secondary glazing, managing indoor humidity is essential. Effective strategies include:

  • Using extractor fans in kitchens and bathrooms to remove moisture at the source.

  • Ventilating rooms regularly by opening windows or using trickle vents.

  • Monitoring humidity levels to keep them between 30% and 50%.

  • Using dehumidifiers in particularly damp areas.

  • Wiping down windows daily during the winter months to prevent lingering moisture.

Extremely happy with my new front door, from date of placing the order to it being fitted I was kept informed.
The guys that fitted it were very knowledgeable and fitted my door, cleaned up and checked if I was happy before they left the property.
I would definitely recommend this company to others.

katie

Efficient and knowledgable
Kevin and Jason did a great job and were efficient and speedy in replacing 5 windows, with the minimum of disruption. There was a measurement error with one of the window casings and they arranged for a new one to be manufactured and installed within 24hrs. Worked around scaffolding that was already on the building.
