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 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 repair 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 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

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.

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.

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 Repair?

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 will multiply according to the number of units.

Similarly, replacing the glass unit of one window may be £50, at the very least. However, for two units, you can expect to pay twice as much. An interesting thing to bear in mind is that, sometimes, if you have a high enough number, the installer might give you a discount for your double glazing repairs.

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 cost will be higher.

What is Being Repaired?

In the previous point in this article, we mentioned that your double glazing is made up of 3 distinct parts.
