Sash Window Repair

Sash Window Repair North Shore Sydney

What are Sash Windows?

A sash window or hung sash window is made of one or more movable panels, or “sashes”, that form a frame to hold panes of glass, which are often separated from other panes (or “lights”) by glazing bars. The term is used almost exclusively to refer to windows where the glazed panels are opened by sliding vertically, or horizontally in a style known as a “Yorkshire light”, sliding sash.

We offer a full range of sash window repair and restoration such as sound proofing, draught proofing, window replacement and refurbishment, re-cording, and resealing. 

Repairing & Restoring Sash Windows

Why do sash windows have draught issues?

Over time buildings move which may cause gaps between the sashes and the frame, or the sides of the window, or gaps around the middle rail. These gaps enable cold air draughts to enter and may cause a rattling noise. As much as 25% of heat loss is caused by the air leakage where your draughts are likely coming in around your windows. Draught proofing will prevent rattles, and provide insulation for your home

How to draught-proof sash windows?

The best way to approach sash window seals is to use the right size and type of draught excluder, such as a rubber seal, for the different parts of the window.

Cost of sash window repair

The cost of repair of sash windows depends on several factors including whether height-equipment needs to be used, difficulty of access, and deterioration of the windows.

Sash Window Repair Case Study

Strata Complex in Mosman
Sash Window Experts Sydney

A strata committee of an art deco apartment complex in Mosman contracted 3 Colours to carry out remedial work and painting of all sash windows at the property. This is a typical request as many buildings still have sash windows – with correct maintenance and professional care, they can have considerable longevity.

On such a large project, owner and tenant communication is crucial to co-ordinate the works as each resident needs to provide access. Aware of the intrusion that can be felt when working on windows, 3 Colours treats each project with sensitivity and professionalism.

The height of the work made it necessary to use scaffolding on part of the building. Erecting scaffolding is always a precise exercise which 3 Colours undertakes with all relevant safety precautions and fully trained professionals. Repairing and painting sash windows is a 3 Colours speciality as it is time-consuming and requires experience in the treatment of timber. Correct preparation is essential to the success of the job. Many 3 Colours sites are within 5 km of the sea – so salt, sun and moisture are the main cause of deterioration of the timber. ​

Additional preparation is fundamental (but not always carried out by all painting companies). At the Mosman complex, 3 Colours removed the old paint with paint stripper and by sanding, then washed off salt residue and mould so the surface was free of any corrosive/harmful substances before application of primer or paint. An oil-based undercoat was then applied, followed by two different coatings. 3 Colours uses marine enamel on the sash part of the window as it provides maximum protection without increasing paint build-up, avoiding any hindrance to the sash window mechanism. ​

Acrylic Weathershield is applied to the window sills to provide additional protection as these horizontal surfaces are more exposed to the harsh elements. 3 Colours has been using this combination successfully for nearly 10 years. Inevitably, unforeseen issues arose. Some windows had previously been painted while closed so were unable to be opened. 3 Colours’ expert painters had encountered this problem before so they knew to scrape all the old paint out of the mechanism, clean it up, prepare it and paint as the other windows. ​

Additionally, some areas of fascia and eaves were in a state of disrepair which would have deteriorated rapidly without attention. 3 Colours notified the strata manager and provided a quote which was substantially lower than a separate quote on a new project. As the scaffolding was already in place and the painting team still onsite, this saved time and money – not to mention inconvenience. ​
