Enhancement and improvement costs

One thing to consider when replacing window glass is whether it might be better to replace the whole window unit.

While the price will be more than just the replacement glass for your window, sometimes it’s the better option if:

• The seal on your window has failed

• The dividers within the window are also broken

• Your window has a wooden frame that has begun to rot

Reasons to replace a window glass

Several reasons might lead to you having to replace a pane of glass in your window...

• Broken panes are the most common cause of window glass replacements, whether it’s a chip, crack or gaping hole.

• Major scratches can be a real eyesore and cause weaknesses in the window glass itself, leading to further damage or shattering.

• Condensation in between double-glazed glass is annoying and generally means the window glass needs to be replaced.

• Draught issues caused by damaged glass or the window pane coming away from the frame.

Wondering if you need energy efficient windows? Whatever your need, from double glazing repairs, to finding an installer, we've got you covered. Even if you can't choose between window types.

Types of window

The cost of window glass replacement will depend on the style of your window. Some of the most popular types of windows are...

Casement windows

These are one the most common types of windows found in UK homes. They’re one of the most versatile options on the market – available in a variety of sizes, materials and finishes.

Sash windows

These windows are most commonly found in Georgian and Victorian homes. They typically feature vertically sliding panes of glass that use a weighted system.

The cost of replacing sash windows will increase if the weight needs to be adjusted.

Tilt and turn

One of the more modern options, tilt and turn windows open inwards into the room making them easier to clean and maintain.

They also allow you to control how wide they open, so they’re ideal for homes with young children.

Bay windows

These are windows that protrude out from the external wall of a home and create a bay area within the room.

They’re a popular choice with UK homeowners for both their style and the ability to add space to a room.

Types of glass

In addition to the type of window you have, the price you pay for window glass replacement will also be affected by the type of glass you choose.

Standard glass

In general, window glass in the UK is generally at a very high standard – in terms of energy efficiency and safety.

Therefore, standard glass should meet most of your basic needs in terms of avoiding draughts, condensation and energy loss.

It’s also the cheapest option for window glass replacement, making it ideal if you’re trying to keep costs low.

Laminated glass

Many homeowners choose laminated glass to provide an extra level of safety. Its protective layer of vinyl between the two pieces of glass gives it added benefits.

These include break-in protection (glass cutters don’t work on laminated glass), sound reduction, and improved impact and shatter resistance.

Toughened glass

Toughened glass is five times stronger than laminated glass of the same thickness, with much higher resistance to breaking.

Consequently using it for the replacement of your window pane will cost more than standard or laminated glass.

Double and triple glazing

Double or triple glazing consists of 2 or 3 panes of glass. The window comes as one completely sealed unit. The air gaps within the unit are typically filled with an inert gas such as argon.

It's these double and triple glazed layers of glass that make these sealed units thermally efficient.

Useful glass replacement checklist

There are a number of things to consider when it comes to replacing glass for windows. So here is a list of checks to make before you contact a glazier or window expert.

Window glass replacement checklist

• Can you identify the type of window and frame?

• What is the reason for new glass?

• Is it single or double pane glass?

• Is it just the glass that needs replacing?

• Could it be more cost-effective to replace the whole window?

• Are there anti-theft blocks fitted?

• Have you considered the type of glass you'd prefer?

• Have you obtained several quotes?

Speak to a window specialist for advice on the best window glass options for you. It is a good idea to get several quotes to make sure you get fair and competitive prices

It is always a good idea to hire an experienced tradesperson to replace window glass so that it's done to a professional standard.

FAQs

Is it cheaper to just replace glass in windows?

Most of the time, the cost to replace glass in the window is cheaper than replacing the whole window.

However, sometimes, if the damage is extensive then it might work out more cost-effective to replace the whole window.

Can I replace just the glass broken on a window?

In most cases, if there's been no major damage to the window itself then you can often simply replace the broken glass.

Although it's worth noting that, if the window has anti-theft blocks then it can make it more complicated to install new glass.

How much does a glass stove top replacement cost?

Rather than a glazier, it is usually a different type of tradesperson that will replace glass for stoves. Hob scratch repair (replacing glass surface) roughly costs around £75. Our oven repair cost guide has more details.
