Why Should I Invest in Double Glazing Repairs?

In certain cases, you may find it is cheaper to repair damaged double glazing than to replace it. For example, if you have old hinges that are threatening to fall apart, it’s cheaper to replace them than replacing the entire window!

Even in the case of cracked glass, you may be able to find double glazing repairs companies that will replace the sealed unit instead of the entire window.

Replacement double glazed units prices can vary. They are, however, cheaper than replacing the whole window. What you need to weigh up is how urgent the double glazing repair is and what your budget is.

It will be certainly cheaper to replace the double glazed sealed units than the whole window. You need to decide if this is cheaper in the long run. If you replace the whole window, frames and all, you will inevitably pay more.

However, your new window should last longer than a double glazing repairs job. Budget is obviously going to play a part. Replacement double glazed units prices are relatively cheap. If you do not have a huge budget at your disposal this may be the best option.

The urgency of having the job done is also a consideration. If you need the window fixed as soon as possible a double glazing repair may be a good solution.

Most window repair companies will be able to offer a quick turnaround for this work. As the cost of replacing misted double glazing units is low this can be great for those needing an urgent repair.

Of course, in some situations, you may have to replace it. If you have a cracked pane as well as a damaged frame, you may have to consider replacing the whole unit.

However, if it does not affect the performance, then double glazing repairs may be more cost effective

Properly functioning double glazing improves your home’s performance. Clean and well-kept double glazing also enhances the visual appeal of the property.

As a result, if you have optimally performing double glazing, the perceived value of your property goes up. This is especially important if you are planning to sell your house.

A broken window handle or a stiff door handle can be more than just a minor inconvenience. They can affect the safety and security of your home.

These are relatively minor double glazing repairs, but fixing these issues can help keep your home safe.

Additionally, a cracked pane of glass looks like an easier target than a fresh and whole one. Even if your doors and windows are secure, a damaged window attracts unwanted attention from potential intruders. Double glazing repairs can help protect your home.

Broken or damaged doors and windows aren’t just unsightly. They can actually affect your heating bills. Double glazing helps improve the thermal efficiency of your home. How well they do it is reflected in their Windows Efficiency Ratings.

However, a damaged double glazed door or window lets out heat. You should prioritise double glazing repairs in such a situation. You may think you are saving money on repairs by not doing so. However, this is false economy as you will end up paying more in heating bills!

If your double glazing’s sealed unit is faulty, or damaged, you will notice condensation on the inside. You may think it’s just a bit of water.

However, you will realise that it’s easier for water vapour to get in than for water to get out. As a result, foggy or misted windows will remain that way for a long time.

This will mean the visibility and natural light will be impaired. Moreover, long-term moisture leads to mould. Since it will be inside the sealed unit, you won’t be able to clean it.

In such a case, double glazing repairs will prevent unsightly condensation as well as mould in your windows and doors.

This acoustic advantage will be lost if the frame is damaged. Having the window repaired will fix this. For a small double glazed window repair cost you will regain a more peaceful property.

What Factors Affect My Double Glazing Repairs Cost?

Double glazing repairs can vary in cost. The money you pay will depend on the scope of the repairs and other factors. Now, what are the factors that can affect your double glazing cost?

How Many Units Need Double Glazing Repairs?

This is obviously a big factor in determining your double glazing repairs costs. Even if it is a faulty window lock, it is around £45 for a single handle repair or replacement. For more than one, your double glazing repairs price will multiply according to the number of units.

Similarly, replacing the glass unit of one window may be £50, at the very least. Sometimes, if you have a high enough number of double glazed window repairs to be carried out, the installer may give you a discount. Otherwise, double glazing repairs are costly and multiple windows will usually cost you the same amount as if you paid individually.

Blown Double Glazing Repair Cost

Has the seal blown? Does your window appear misty? This is one of the most common reasons for replacing a double glazed unit.

The cost of replacing misted double glazing units will be cheaper than replacing the whole window.

Your blown window repair cost will of course vary depending on the specification of the double glazed window to be fixed or replaced.

What is the Quality of the Part that Needs Double Glazing Repairs?

A double glazed unit consists of the frame, sealed unit, and the hardware that accompanies it.

There are usually three options of frame material – uPVC, aluminium and timber.

The sealed unit could have regular float glass or specialised glass. The fittings can be things like ordinary stainless steel hinges or special anti-theft hinges. The handles of the doors and windows may be plain white, or have a special finish.

Different materials and qualities mean different prices. As a result, you may pay less for a standard quality or cheaper material. However, if you need repairs on higher quality products or materials, their replacement window cost will be higher.

What is Being Repaired?

In the previous point in this article, we mentioned that your window is made up of 3 distinct parts, so your double glazing repair cost will vary according to those different elements that may need to be replaced.

While the quality of the individual part is an important factor, the part itself also makes a difference. For example, repairing the glass unit or the frame will be more expensive than replacing the hinges, lock, or door handle.

Condensation on Double Glazed Windows

When moisture in the air suddenly cools and condenses on a cold window, you get condensation. Well insulated (Low E) double glazing will help prevent condensation from forming on the interior of your window. Replacement glass units or replacement double glazed windows are recommended for windows with condensation.

How Do I Know If My Double Glazing Needs Repaired?

There are four tell-tale signs that your double glazed windows need repair or replaced: There are chips and cracks in the panes of glass; there is condensation (misted windows) between the two panes of glass; the window allows cold air through; water begins to seep through the frame. If your double glazing does any of these things, you may need to get your double glazing repaired or replaced.

Is uPVC Flammable?

No, uPVC isn’t flammable and is actually a fire retardant.

What Can Cause Double Glazing To Crack?

Double glazing can crack for what appears to be no particular reason at all. A sealed window unit faces constant pressure either side of the glass, however, most of the time double glazing is strong enough to deal with this. Winter can be one of the worst time for cracked glass as the difference of temperature on either side of the glass stressing it to the point it can crack.

How Do I Know If My Double Glazing Needs Replaced?

Double glazing will need replaced after a while due to the nature of the design – the gas that separates the two window panes slowly leaks out over time meaning the energy efficiency of your window is compromised. If your double glazing allows cold spots; water to seep through the frame; has cracks or chips in the window or has a build-up of condensation between the two panes of glass (misted windows), you should probably look into getting your double glazing replaced or repaired.
