Sash Window Repairs – Sydney

They’re beautiful, they’re traditional, and they add a touch of elegance to any home – but sash windows can be notoriously difficult to maintain, at least without proper guidance. From daily dusting and cleaning to ensuring the mechanisms are properly oiled, sash windows require regular care in order to keep them functioning correctly.

In this article, we’ll take a look at sash windows, the different types available, the benefits they offer, some maintenance tips to keep them in good condition, and why Inner West Window Specialists are the go-to choice for sash window restoration and repairs in Sydney.

Sash Window Basics

Sash windows are named such because they have two or more panels (called “sashes”) that slide up and down in a frame. The sashes are separated by bars called mullions, and they’re usually held in place by weights hidden within the frame.

These windows have been around for centuries, that’s why they’re also called heritage windows. In fact, the first ones are thought to have been invented in the 14th century in Europe. These windows eventually became very popular in England in the 19th century, and the popularity hasn’t died down since.

Originally designed to be opened by pushing up on the bottom sash, many modern sash windows are now equipped with a mechanism that allows both sashes to be opened.

In Australia, these windows are most commonly seen in older homes. But despite their old-fashioned charm, they are still a popular choice for new builds – and it’s not hard to see why.

Many traditional sash windows, also called heritage timber windows, are made of wood. However, some newer models are made of PVC or other materials. For example, some are aluminium windows, although they might work differently than your usual heritage timber window.

A Variety of Styles

For such an old-fashioned window, there is a surprisingly large variety to choose from:

Double-hung windows

Double-hung sash windows have two sashes that move independently of each other – one sash slides up, while the other slides down.

Single-hung windows

Another common type of sash window is the single-hung window. This type of window has only one moving sash, with the other sash being fixed in place.

Box frame windows

The term box frame is often used interchangeably with sash because most traditional windows feature box sashes.

The Many Benefits of Sash Windows

These windows come with many benefits, and that’s why to this day, many homeowners choose to keep their heritage sash windows, upgrade them, or install modern versions. Below are some of the benefits offered by these popular windows:

Energy efficient, thanks to tight seals

These windows are well-insulated, thanks to their tight seals. The seals also help to keep out draught, making the windows more energy-efficient than other types of windows. In fact, installing them can help to improve the energy efficiency of your home by up to 20%, reducing your energy bills in the process.

Noise reduction

This is also due to the tight seals, which stop outside noise from coming into your home. If you live in a busy area or near a main road, sash windows can make a huge difference to the level of noise you hear inside your home.


Thanks to the way they are designed, it is very difficult for intruders to force these windows open. Sash windows also usually come with locks as standard, which adds an extra layer of security.

Offer great ventilation

In the summer months, you can open up your sash windows to let in a cooling breeze. In the winter, you can open them slightly to help ventilate your home and stop condensation from building up.


While this is of course a matter of personal taste, there’s no denying that sash windows add a touch of elegance to any home. The wide variety of styles available means that there’s sure to be a sash window that’s perfect for your home.

Easy to clean

Since the sashes move up and down, you can easily reach both the inside and outside of the window for cleaning. When it comes to cleaning the outside of your sash windows, you can simply lean out and reach them with a cloth or brush.


When properly maintained, these windows can last for many years. In fact, many sash windows that were installed centuries ago are still in use today. That’s a testimony to their durability.

Common Problems (and How to Fix Them)

Despite their many benefits, sash windows can sometimes run into problems. If your home has these windows, you will experience any of the following issues. Don’t fret, these are very common and can be easily resolved.

The window is hard to open or close.

This is usually caused by the weights being out of alignment. The fix is to adjust the weights so that they’re evenly balanced.

The window is draughty.

If your sash window is letting in cold air, the problem is most likely a seal that’s come loose. You can try to reseal the window yourself, but a professional may need to do it for you. Learn more about draught sealing sash windows in Sydney here.

The window is stuck.

If your sash window is stuck and you can’t open or close it, the problem is probably a build-up of paint or debris. Try using a putty knife to remove the paint or debris, and then lubricate the window with a silicone-based spray.
