Can I Dry Out Blown Windows Myself

It can be annoying when your window view is obstructed by fog or mist that doesn’t fade no matter how often you wipe or clean.

Sound familiar? Then unfortunately, you may be dealing with blown windows.

As a leading window repair company, we often get asked ‘Can I dry out blown windows myself?’. And unfortunately, the short answer is no.

In this guide, we will help you understand what causes this frustrating problem and whether those DIY repair videos that you may have seen online truly work. We will also give genuine advice on the best way to solve your blown window problem.

Understanding Blown Windows Inside Double Glazing Units – By Misted Window Repair Glasgow Professionals

Double glazed windows comprises of two glass panes that are separated by a sealed space filled with air or argon gas. This area creates thermal insulation for your home, keeping the heat inside whilst the cold weather outside where it belongs.

So why has my window blown?

A ‘blown window’ refers to a failure in the seal around the double glazed unit. This causes moisture filled air to enter between the double-glazed window panes, where it gets trapped inside. As temperatures change, the moisture condenses and forms a foggy or cloudy appearance inside the window. And because the moisture can’t escape, it becomes trapped and no amount of cleaning with allow it the escape.

Because of this misty appearance, blown windows are also commonly referred to as misted windows.

It’s important to know that seal failure doesn’t happen overnight. It’s a gradual process that develops over time. Common causes include temperature fluctuations, poor installation, and manufacturing defects of your window frame.

Can I Dry Out Blown Windows Myself?

The short answer is no. Unfortunately, you can’t dry out blown windows yourself.

You may have come across some DIY videos online to ‘fix’ your blown window. But as blown double glazing professionals, we must warn you that these solution are very hazardous and only offer temporary fixes.

If you have a window warranty, you can almost certainly guarantee that trying any of these solutions will void your protection.

The DIY fix you might have come across involves drilling tiny holes into the glass unit to let warm air flow through and dry out the trapped moisture, then sealing the holes again afterward.

This method compromises the window’s insulation properties, releasing any remaining argon gas that was helping to provide thermal efficiency. And because the broken seal hasn’t been corrected, the moisture will re-enter over time.

Why DIY Solutions Often Disappoint

Despite the DIY videos of ‘How to fix a blown windows‘. The truth is that once a sealed unit has failed, it can’t be properly restored using household tools and materials.

Drilling into the unit or the glass is one sure way to reduce thermal efficiency even further, whilst spoiling any warranties on your windows. It is also very difficult to do safely, and may result in the whole window shattering. Turning your problem even larger.

If you manage to drill the holes successfully, any improvements to the condensation will only be short-lived as moisture gradually returns through the compromised seals.

That’s why, if condensation forms inside the panes of your double glazing, it’s always best to rely on a reputable company to fix the problem properly.

Professional Solutions to Solve Blown Double Glazing

For a lasting solution that restores your home’s thermal efficiency and saves you on your heating bills, you will need professional repair or full window replacement.

Double glazed repair involves removing the sealed glass unit and replacing with a new unit, whilst keeping your existing frames. This tends to be the most cost friendly option, however is not advisable for frames which are old, damaged, or warped.

You also have the option to install a brand-new unit with a new frame included. This option is better if your frames are reaching towards the end of their lifespan and show serious signs of damage.
