How Do I Fix Misted Double Glazing?

24th February 2024 |

Double Glazing

Misted Double Glazed Window

With winter encroaching, adverse weather and damp are just around the corner.

Misted double glazing can be a significant nuisance for homeowners across the UK, particularly during the colder months where the drop in temperatures can lead to increased dampness.

This misting, a form of condensation between the panes of your double-glazed windows, not only obstructs your view but also compromises the thermal efficiency of your windows. If you’re facing persistent fogging or condensation inside your windows, it’s a sign that the seals might be failing.

In this guide, we’ll dive into why this happens and provide you with effective strategies to resolve the issue, ensuring your windows are clear and fully functional.

Why is there misting within my double glazed windows?

It’s important to note that condensation on the outside of your window is perfectly normal. External mist is a sign your windows are functioning properly, by keeping moisture and damp out of your home. However, if you’ve noticed condensation and misting in between your glass panes, it’s usually a warning sign that your windows are probably not sealed adequately.

When the seals around your windows deteriorate, moisture can enter the space between the glass panes, resulting in condensation and misted double glazing. Resolving this issue typically requires professional intervention, often involving a replacement of the affected glass.

Seals don’t fail overnight. However, if your property has older style windows then it’s likely that your seals have naturally worn out over time. Abrasive chemical cleaners can also harm your window seals and cause permanent damage to your glass unit.

To ensure your home stays properly insulated through the colder months, it’s important to resolve this issue as soon as possible. If your double glazing is not functioning properly, you could encounter several issues that can result from cold, wet weather such as damp, mould and mildew. Without proper seals, you could also face costly utility bills further down the line.

Is it worth replacing misted windows?

If your windows are older, you might want to consider replacing both the frames and glass units. Broken seals typically occur in older windows and there’s a chance your existing windows have reached their use-by date. Window fabrication has come a long way in recent years and you might want to consider modern aluminium or uPVC windows. Your choice will depend on the unique specifications of your property and your own unique tastes.

Interior window condensation is also a sign it’s time to refurbish your property. If you find yourself regularly wiping down your windows, then your interior spaces will be at risk of mould, mildew and damp. It’s important to ensure your home is sealed to an appropriate standard to ensure it stays warm and dry.

uPVC windows

Suitable in both contemporary and traditional homes, uPVC windows have become an increasingly popular choice for homeowners in recent years. Highly durable and resilient in the face of adverse weather, modern uPVC windows have a long lifespan and will continue delivering optimal energy efficiency ratings for years to come.

Aluminium windows

Aluminium Windows For Somerset Home

Aluminium windows can make an attractive and practical addition to your property.

The fabrication of aluminium windows has come a long way in recent years. Traditionally used in commercial properties for strength and durability, advancements in thermal break technology have allowed manufacturers to engineer slimmer, more energy-efficient frames that are suitable in both traditional and contemporary homes. At Majestic Designs, our aluminium windows are thermally broken using polyamide which provides excellent levels of insulation.

Frequently asked questions

  • How can I prevent steamed up double glazing?

    To prevent misted double glazing, it’s important to manage indoor humidity levels and improve air circulation within your home. By reducing the indoor humidity, you minimise the amount of moisture in the air that can condense on cold surfaces like your window glass. Effective ways to achieve this include using extractor fans in moisture-heavy areas, such as kitchens and bathrooms, opening windows regularly to allow fresh air circulation and using dehumidifiers to actively remove moisture from the air. Together, these strategies help to maintain clear and condensation-free windows.

  • Why is my glass window misted on the inside?

    If you notice your double glazing is misty, it indicates that moisture has penetrated the space between the glass panes. This misting is typically a sign of a compromised seal within the double glazing unit. Several factors can lead to the degradation of these seals, including the age and condition of the window frame, external pressure on the window and damage from harsh chemical cleaning solutions.

    When seals fail, not only does water vapour enter, but the window’s insulating properties are also diminished, leading to increased heat loss. If cleaning the windows doesn’t remove the misting, because it’s between the panes, the only solution is to seek professional help to repair or replace the affected unit.

  • Can replacing the glass units get rid of condensation?

    Misted double glazing doesn’t always require a full window replacement. If the window frames are still in good condition, you can often just replace the glass units to resolve the issue. Replacing the double glazed unit can restore the window’s functionality and eliminate the condensation problem by reintroducing proper sealing and insulation.

  • How long should double glazing last before misting?

    Double glazing is designed to be durable and long-lasting. Under ideal conditions, double-glazed windows can last between 20 to 30 years before issues such as misting begin to occur. The lifespan of your double glazing can depend on several factors, including the quality of installation, the materials used and the environmental conditions to which the windows are exposed. Regular maintenance and prompt window repairs to minor damages can also extend their lifespan.
