What are the Benefits of Sash Window Maintenance?


An extended life on your sash windows

Sash Windows last for generations if they are correctly repaired and maintained. We will carry out repairs that are needed to extend the life of your sash windows.

A reduction of dirt and dust in your home

Sash windows have lots of different parts that need cleaning regularly. If you fail in cleaning your windows regularly, they can get dirty and dusty over the period of a year or so.

Savings on energy bills

By maintaining your sash windows properly, you can cut down your household expenses as they have an automatic ventilating feature.

Additional value to your home

If your sash windows are in working order you will attract a number of benefits that will bring great value to your home.

Improved security of your home

Windows that are not properly maintained can seriously weaken the security of your home. Any intruder will be taking advantage of fractured wood frames, loose or broken locks on double glazed windows and wonky hinges. Regular window maintenance ensures you have a secure house that would put burglars off.

Reduced draughts

Draught is a common problem in the winter months. It’s caused by cold air leaking into the home, through gaps around windows or from broken seals around window frames. Sash windows have many small gaps (or ‘voids’) created by their design which in turn contributes to draughts as well as being a prime food source for mould. A well-maintained sash window will reduce draughts and maintain an even temperature throughout the house.

Reduced exterior noise

Sash windows maintenance also reduces the external noises getting in your home which is linked to poor health.

Easier sash window operation

Sash windows are a beautiful traditional window that adds character to your home, but due to the age and unseen wear and tear they can be noisy and in need of fixing. Sash windows maintenance guarantees the ease of operating your sash windows over time.

When Do Your Sash Windows Require Maintenance Services?


Poorly applied paint

Poorly applied paint can develop cracks and peeling which may result from its sagging, warping or shrinking. Our skilled tradesmen offer a fully guaranteed repainting service using only the highest quality paints to bring back that original look of your sash windows.


Draughts are one of the most annoying problems with sash windows. Even in still air, draughts can be felt as soon as the window is opened. If you have creaky wooden sash windows they require regular maintenance to remain draught-free.

Better sound insulation

Improved sound insulation is yet another advantage of sash replacement. Replacing the sashes and hinges with durable, maintenance-free versions means you get a more solid product – one that’s better at stopping noise from getting in and out.


Damp is one of the most common issues that affect sash windows. Lack of ventilation accelerates damp conditions in a house which can lead to more severe problems if left untreated.


Due to the age of your sash windows, they may be struggling to operate smoothly. If your sash windows are stiff and difficult to open and close, you might need maintenance services. There may also be parts that are no longer operational and require repair or replacement.
