When it comes to window repairs, a stitch in time saves nine! Proactively making repairs on your double glazed windows and doors can be the difference between a simple fix and a full replacement.

The latter can be costly and time-consuming, so acting in good time to get repairs is essential if you wish to avoid a full replacement of your double glazing.

But how do you know when it’s time to repair double glazing? How costly are repairs vs replacements? This guide will help you recognise faulty double glazing and advise you on repairs.

The importance of double glazing in your home

Double glazing features two glass panes that are separated by a thin gap which is usually filled with insulating gas. The two glass panels, combined with the gap in between, are designed to provide excellent insulation for windows and doors. The entire sealed unit prevents heat loss and helps in maintaining comfortable temperatures in your home.

When any one element of double glazing fails, it cannot insulate your space effectively.

Insulation is crucial in not only keeping homes at consistent temperatures and retaining heat during the winter but also in reducing a property’s carbon footprint and a homeowner’s energy bills.

How do you know if your double glazing needs repair?

There are several signs that your double glazing needs repairing.

One of the most obvious and apparent signs is that your home struggles to retain heat and your heating costs are sky-high! This could mean that your double glazing isn’t working as well as it should. This could be due to the age of your double glazing, a failure of the unit (caused by a manufacturing error) or damage to the window seals.

Visible damage such as cracks or damage to window frames can also indicate repair, alongside handles that are stuck or won’t open properly.

Other signs such as draughts, cold spots and excessive external noise might also indicate that it’s time to repair your double glazing!

Does condensation mean that my double glazing needs to be repaired or replaced?

Not necessarily – although this depends on the location of the condensation!

Another sign that your double glazing needs to be repaired is condensation between the panes. This means that droplets of moisture are getting into the space between the two panes of glass, limiting its insulating capabilities.

Condensation or misting on the inside of your windows simply means that humid air is hitting a colder surface (e.g. your window). This can be due to a number of reasons, such as high humidity levels in your home and poor ventilation. This isn’t, however, necessarily a sign that your double glazing needs replacing, but if this happens frequently it may indicate that your home isn’t maintaining consistent temperatures.

Condensation on the outside of your window isn’t usually a cause for concern and is generally related to external moisture and varying weather conditions.

Double glazing repair vs window replacement

How do you know whether it’s best to repair or replace?

It can be difficult to know whether repair or replacement is the best option when it comes to double glazing. It’s important to consider whether the problem is an isolated issue or a fault with the entire window unit. If the rest of the window is in relatively good condition and it is still relatively new, a repair is usually a good choice and the best course of action.

At Futureglaze, we can assess the problem with your double glazing and advise you whether a repair is appropriate or if entirely new windows are needed. Our experienced engineers always try to proactively solve the issue with repairs as the first step where possible, leaving replacement with new double glazing as a last resort.
