How to Arrange Blown Double Glazing Repair in Stamford
Noticed foggy windows, condensation between the panes, or a chilly draft creeping in? These could be tell-tale signs of blown double glazing.
Many homeowners in Stamford experience double glazing issues over time, especially as windows age or if poor installation has compromised the window seals.
Stamford properties offer the charm of heritage builds, but this often comes with old windows that need updating. It’s common for these older windows to blow.
Left unaddressed, blown windows can impact energy efficiency, causing higher energy bills. It can lead to moisture ingress, which can damage surrounding window frames and glazed windows.
Most often, blown double glazing needs replacing. While blown double glazing repair is possible in some modern windows, it’s not the best practice.
Replacing blown double-glazed windows restores your home’s insulation and reducing energy costs.
Let’s explore your options further.
This guide walks you through what causes blown double glazing, how to spot the signs, and what steps you need to take to arrange blown double glazing repair in Stamford.
What Is Blown Double Glazing?
A blown double-glazed unit occurs when the sealed unit inside your double glazing fails. This allows excess moisture to enter the window panes.
Over time, this moisture builds up, creating misty windows. This foggy appearance ruins the clarity of the glass.
Each double-glazed window unit consists of two panes of glass filled with gas. When the window seals break, the gas escapes, reducing thermal performance and causing condensation on windows.
The Science Behind Blown Double Glazing
Understanding how double glazing works is key to knowing why blown windows need replacement rather than repair.
Modern double-glazed windows are designed to be energy-efficient, reducing heat loss and keeping homes warm while lowering energy bills.
But when a glazed window fails, these benefits disappear.
Here’s how double glazing works:
- + A double-glazed window consists of two panes of glass
- + There’s a sealed air gap between them
- + This gap is often filled with argon gas, providing thermal insulation and reducing energy loss
The window frame and window seals are essential to keeping this sealed unit intact, preventing moisture ingress.
So what happens when a double glazing unit fails?
Over time, double glazing window units can suffer from broken seals, leading to a buildup of moisture between the glass panes.
This creates the well-known signs of a blown double-glazed window:
- *Cloudy windows or a foggy appearance
- *Misty windows with visible water droplets inside
- *Reduced thermal efficiency and higher energy bills
- *Increased noise penetration from outside
A blown double-glazed unit means the argon gas has escaped so the window unit is no longer effective.
Deterioration of window seals is one of the most common issues leading to double glazing repairs.
But Why Does Double Glazing Fail?
There are several factors that contribute to blown double glazing…
- Age – Older double-glazed windows are more prone to seal failure
- Poor Installation – If the window frame was not properly fitted, stress on the sealed unit can cause early moisture ingress
- Harsh Cleaning Chemicals – Some cleaning products can degrade the window seals, causing a blown window over time
- Extreme Weather – Sudden temperature changes can cause the glass for windows to expand and contract, leading to seal failure
Once a double glazing unit fails, it can’t be repaired to its former performance. Temporary DIY fixes may tide you over for some time, but the windows won’t have the same energy efficiency level.
Only window replacements or professional repairs can restore energy efficiency and improved insulation.
5 Tell-Tale Signs of Blown Double Glazing
If you’re noticing a decrease in energy efficiency in your Stamford home or a cloudy appearance between your windows, they’re likely blown.
Here are the major signs that indicate your current windows have blown and you need a Stamford window repair service to replace them.
1. Foggy or Cloudy Windows
The most common sign of a blown double-glazed window is a foggy appearance between the panes of glass.
If you notice that your glazed windows look permanently misty despite cleaning, this is a clear indicator that the sealed unit has failed.
2. Internal Condensation Between the Panes
A fully functional double-glazed window unit shouldn’t allow moisture buildup inside the glass unit.
If you see condensation in windows, it means moisture ingress has occurred due to a broken seal.
3. Higher Energy Bills
A damaged window unit no longer provides adequate insulation, forcing your heating system to work harder.
If your energy bills have increased unexpectedly, it could be due to blown double glazing.
4. Cold Drafts and Poor Insulation
If you feel cold drafts near your windows or notice a drop in temperature inside your home, your double glazing window units may be compromised.
A failed sealed unit allows heat loss, leading to energy inefficiency. It’s time to hire double-glazing installation specialists before your energy bills skyrocket.
5. Noise Penetration
Quality double-glazing windows also act as a noise reduction barrier.
If external sounds seem louder than usual, it could indicate damaged windows that need a double glazing repair service.

Blown Double Glazing Repair vs. Replacement: Which Is Best?
Do you really need to replace the entire window unit? Or can you simply repair the glass?
Here’s what you need to know about blown double glazing repair vs replacement.
When Is Blown Double Glazing Repair Possible?
In some VERY RARE cases, minor issues with double glazing units can be repaired instead of opting for a complete window replacement.
In terms of blown double glazing repair, some professional glazing companies may offer desiccant replacement, which absorbs the moisture buildup inside the sealed unit.
Other repair techniques include:
- Sealing minor cracks with silicone sealant
- Replacing a broken glass pane
- Using a window repair kit for temporary fixes
However, regular maintenance is required to prevent the issue from recurring. So, while repair might seem like the cheapest option, you’d have to keep carrying out these procedures. The cost builds up over time despite the window never being restored to its full performance.
When Replacements Are Necessary
In the end, blown double glazing repair won’t cut it. You’ll need to replace blown Stamford windows.
Investing in new, energy-efficient double glazing ensures long-lasting results, thermal efficiency, and better noise reduction.
A-rated energy-efficient glass can also improve your home’s overall energy consumption and attract potential buyers if you plan to sell.
What About DIY Fixes for Blown Double Glazing – Do They Work?
When faced with blown double-glazed windows, many homeowners wonder if there’s a DIY fix that could save them from the expense of a full window replacement.
The internet is full of so-called quick fixes, but is there a cheaper solution that actually works?
Let’s explore the most common DIY repair attempts and whether they work as lasting effective solutions.
- Window Repair Kits – Some homeowners try using sealant repair kits to reseal window panes and stop moisture ingress. These kits may claim to provide a fix, but they don’t restore the sealed unit or prevent future foggy windows.
- Drilling Holes in the Glass – One widely circulated “hack” involves drilling small drainage holes in the bottom of the glazed unit to let out trapped moisture. While this may temporarily reduce condensation, it destroys the insulation properties of the double glazing unit, worsening heat loss.
- Using a Dehumidifier – A dehumidifier can help reduce moisture buildup inside a home, but it does nothing to fix window seals or restore the energy efficiency of a blown double-glazed unit.
- Applying Anti-Condensation Film – This plastic window film is a temporary solution that may help with double glazing condensation but does not stop the deterioration of window seals.
Unfortunately, DIY fixes simply won’t work long-term.
While some of these fixes might reduce the symptoms of misted windows, none of them address the underlying problem — the appearance of condensation comes down to the failure of the sealed unit.
Blown double glazing means the argon gas glass between the panes of glass has escaped, and the insulation properties have been lost.
No DIY fix can restore the integrity of a blown double-glazed unit, meaning energy bills will continue to rise due to poor insulation.
For a long-lasting solution, the only real fix is professional repairs or complete replacement.
Choosing a professional glazing company is the only answer.
Stamford’s most reliable double glazier, Aperture Winodw Group, ensures your window unit is replaced with a new, energy-efficient one, improving both thermal performance and home comfort.
The Hidden Costs of Ignoring Blown Double Glazing
Some homeowners ignore blown double-glazed windows, assuming they’re just a cosmetic issue.
However, delaying double glazing repairs can result in higher costs and damage to window frames.
But that’s not the only issues that come with not replacing blown windows in your Stamford home in time. Let’s explore.
Increased Energy Bills
A blown double-glazed window loses its insulation properties, allowing cold surface temperatures inside and forcing your heating to work harder.
This leads to increased energy bills. In Stamford’s colder months, a blown window means energy consumption will spike.
Moisture Damage to the Home
When a glazed window fails, it allows excess moisture to collect inside.
Over time, this causes:
- Mould growth on window frames and surrounding walls
- Deterioration of window seals
- Damage to plaster, wallpaper, and wooden sills
Ignoring moisture buildup from a blown double-glazed unit can result in costly repairs beyond just the window replacement.
Structural Weakness and Security Issues
A blown double-glazed window isn’t just a thermal performance issue. It also weakens window security.
Broken seals and damaged windows can make window panes easier to break, compromising home security.
Reduced Property Value
Potential buyers often check for condensation in windows as a sign of double glazing issues.
Blown double glazing makes a home look neglected, affecting curb appeal and lowering its market value.
Poor Noise Insulation
A blown window allows external noise to enter more easily.
If your home is near a busy road, school, or commercial area, this means increased noise penetration and a less comfortable living environment.
Ignoring blown double-glazed windows might seem like a way to save money, but it leads to higher energy bills, property damage, and potential security risks.
Arranging a double glazing repair service with a professional glazing company ensures long-lasting results and improved insulation.
