How to Fix Sash Windows in Sydney Homes

For homeowners in Sydney, sash windows can be a beautiful and classic feature. However, over time, these windows can start to show signs of wear and tear, becoming difficult to open and close or even letting in drafts. If your sash windows are in need of repair, this guide will walk you through the process step-by-step.

What are Sash Windows?

Before we dive into sash window repairs, let\’s quickly go over what sash windows actually are. Sash windows are a type of window that is made up of two movable panels or \”sashes\” that slide vertically in grooves on either side. One sash moves up while the other moves down, allowing for ventilation. Sash windows were a very popular style in Sydney homes built before the 1960s.

Common Sash Window Problems

There are a few common issues that can affect the operation of sash windows over time:

Broken sash cords are very common.

Sticking/Not Opening Smoothly This is often caused by the build-up of paint or debris in the window tracks, making it harder for the sashes to slide up and down. Warping of the wood can also cause sticking.

Drafts Gaps forming between the sash and window frame due to shrinking or swelling of materials can lead to drafts entering the home. Broken panes of glass will also cause drafts.

Rattling Loose joints in the sash or frame allow the window to rattle when it\’s windy outside. This can be incredibly annoying!

Water Damage/Rot Since sash windows have many different components, water finding its way into the wrong areas can cause rot and deterioration over time.

Tackling these issues requires a little bit of elbow grease, but can be very satisfying! Let\’s look at some sash window repair tips.

Dealing with Broken Sash Cords

One very common repair for older sash windows is re-cording or replacing the rope cords that help operate the moving sashes. These cords run vertically inside the window frame and are attached to weights hidden in internal boxed areas. As the ropes age, they can fray and snap, causing the sash to become inoperable.

To re-cord sash windows:

1. Remove the sash and access the weight compartments
2. Detach the broken cord remnants from the weights
3. Feed new nylon re-cording rope over the pulley at the top and tie it securely to each weight
4. Reinstall the sash, making sure the new cord can move freely
5. Add weatherstripping or lubricant around the sash as needed

How to Fix Sticking Sash Windows

1. Clear Out Debris The first step is removing any built-up paint, dirt or debris from the window tracks using a stiff brush or putty knife. Go slowly and take your time.
2. Sand Rough Areas Lightly sand any areas with flaking paint or rough wood to create a smooth gliding surface again.
3. Clean Tracks Clean the empty tracks thoroughly using a vacuum cleaner.
4. Lubricate Apply a silicone-based lubricant along the freshly cleaned tracks. This will allow the sashes to glide smoothly.
5. Adjust Sashes if Needed If the sashes still stick after lubricating, you may need to lightly plane or sand them down to adjust the fit within the frame.

Stopping Drafts in Sash Windows

Drafts can make your home less comfortable and increase energy costs. Here\’s how to seal drafty sash windows:

1. Reglaze Loose Panes If any panes of glass have come loose, carefully reglaze them using a glazing compound to lock them back in place.
2. Replace Weatherstripping Weatherstripping that has become brittle or torn should be removed and replaced. You can purchase self-adhesive weatherstripping designed for windows.
3. Caulk Gaps and Cracks Use a high-quality exterior caulk to seal any gaps or cracks between the window frame and surrounding area.
4. Consider Window Insulation For a more comprehensive solution, you can insulate sash windows using solutions like removable rope caulk or thermaswrap window insulation film.

Fixing Rattling Sash Windows

That incessant rattling from loose sash windows can drive any homeowner crazy! To stop the noise:

1. Tighten Joints Check all joints and reattach the sashes or outer frames if they have come loose using appropriate screws or construction adhesive.
2. Add Window Shims If there is still a bit of excess play, you can discreetly shim the window in tight spots using small wooden shims.
3. Install Window Locks Sash window locks that press the operable sash against the outer frame can help minimize rattling.
4. Apply Weather-Sealing Applying permanent weather-seal products around the perimeters of the sashes will restrict their movement and dampen noise.

Unfortunately, water damage and rot are best repaired by replacing the affected components like sash rails, stiles or outer frame sections.
