Tips to Combat Window Condensation in Your Home

Leamington Editorial 19th Mar, 2024   0

Window condensation is more than a simple annoyance; it can lead to problems like dampness and mould. Excessive moisture in homes can result in respiratory problems, infections, and compromised immune systems.

In this article, we’ll explore some of the practical and effective solutions to address condensation on windows, focusing on how best to manage moisture, improve ventilation, and enhance insulation.

While replacing your windows is a sure way to improve your homes energy efficiency, and prevent condensation, double glazed windows prices in the UK may be unfeasible for many. That’s why we’ve selected some of the best small-scale tips that can act as interim solutions to your condensation problems.

1. Upgrade your windows

To minimise condensation, it’s crucial to opt for windows with more than one glass pane. Single-pane windows are highly vulnerable to cold weather, leading to increased water vapour production.

Double or triple glazing mitigates this issue by incorporating an internal layer of trapped air, preventing the glass from getting excessively cold. However, for some, double glazed windows prices in the UK might not be feasible.

2. Anti-Condensation Paint

One solution involves applying anti-condensation paint on walls to absorb and retain heat, preventing condensation. This specialised paint not only absorbs and retains heat but also prevents the formation of condensation. You should choose a product that suits your needs and local climate conditions and you should opt for a paint that promotes breathability. This will help to prevent the trapping of moisture within the walls.

3. Penetrating Damp Solutions

Waterproofing exterior walls is essential to prevent moisture absorption. Choose highly breathable products like Emperor Masonry Paint or Emperor Masonry Cream to create a hydrophobic surface that protects against penetrating dampness. This not only safeguards the brickwork but also prevents interior walls from becoming saturated which inhibits black mould growth.

4. Silica Gel Packets/Moisture Traps

Strategically placing silica gel packets near windows can absorb excess moisture before it reaches surfaces.

These packets are versatile and effective in various applications, from preventing rust to preserving moisture-sensitive items. The absorption efficiency depends on their size and hardness, with larger particles offering higher absorption rates.

By strategically using these packets, you can efficiently absorb excess moisture before it reaches surfaces, contributing to a drier and healthier environment.

5. Window Vacuum

Investing in a window vacuum provides a practical solution for efficiently eliminating condensation from windows.

Starting from the top and working downwards, pay careful attention to corners and edges for thorough results. Regular use, especially in cold and wet weather, can significantly reduce moisture levels in your home.

Opt for a cordless model for added convenience and ensure the water tank is regularly emptied to maintain optimal performance.

6. Dehumidifier

For even more optimal results, you should consider combining a window vacuum with a dehumidifier. A dehumidifier plays an important role in minimising overall moisture in the air, subsequently reducing the frequency of condensation on windows.

Select an energy-efficient model tailored to your home’s size and specific needs. The placement of your dehumidifier, such as on a second-floor landing, effectively draws moisture from bedrooms and bathrooms, contributing to a drier and healthier indoor environment.

7. Anti-Fogging Spray

To repel water vapour on windows or bathroom mirrors, you can use an anti-fogging spray. This specially formulated liquid creates a thin film that prevents the formation of water droplets, ensuring clear visibility.

Administered through a spray bottle, it’s essential to apply the spray uniformly onto the object’s surface and allow it to dry.

In certain instances, specific fog-resistant sprays may require a second application to guarantee optimal effectiveness in maintaining visibility and preventing condensation.

Ventilation tips

One of the easiest and cost effective ways to fight again condensation and mould is simply by ensuring better ventilation through your home.

Effective ventilation helps expel moist air and replaces it with fresh, dry air, reducing the conditions conducive to condensation. Here are some practical ventilation options to consider:

1. Natural Ventilation

Allowing moist air to escape by either opening windows or utilising window trickle vents is a straightforward method to mitigate condensation.

Passive ventilation, relying on natural forces for airflow, presents an economical and easy-to-maintain solution. However, this approach may prove insufficient, particularly in problematic areas.

2. Heat Recovery Ventilation

Taking ventilation a step further, Heat Recovery Ventilation (HRV) systems replace indoor moist air with filtered, fresh air from the outdoors.

These systems incorporate a heat exchange unit, capturing warmth from the outgoing air and using it to heat the incoming fresh air. This process not only significantly diminishes heat wastage but also contributes to reduced energy bills.

3. Positive Input Ventilation

For comprehensive home ventilation, Positive Input Ventilation (PIV) systems continuously exchange indoor moist air with fresh, filtered air from the outside. Commonly installed in lofts, PIV systems eradicate condensation throughout the entire home.


Effectively treating condensation on windows requires a comprehensive approach, addressing the root causes of moisture, poor ventilation, and insulation inefficiencies. By incorporating practical solutions such as anti-condensation paint, window vacuums, dehumidifiers, and anti-fogging sprays, you can create a healthier home environment and mitigate the risks associated with dampness and mould.

Remember to choose products that align with your unique requirements and conditions, and consider seeking professional advice if you’re uncertain about the best course of action for your home. Taking proactive steps to manage condensation will not only improve your living conditions but also helps to create a healthier and safer home for you and your loved ones.
