A classic feature of homes since the 17th century, timber sash windows offer style, elegance and functionality to both modern and period properties. However, to keep them looking their best, they need to be regularly maintained and cleaned.
Without proper maintenance, timber becomes worn which can cause issues like rotting, which then causes the sashes to become stiff or let in draughts. Cleaning sash windows can seem like a big job, but there are plenty of techniques that make the job easier.
Don’t be put off timber sash windows by the need for maintenance! Choosing wooden windows is still an excellent choice. At Todi & Boys, all of our wooden sash windows are crafted from high-quality timber and come with a guarantee.
This means you’re getting the classic effect of wood while also getting long lasting beauty and performance. Keep reading our blog to learn why cleaning sash windows is important, how to clean sash windows, how to maintain timber frames and more.
Over time sash windows can become grimy and dusty, if neglected, this can build up and stop the window from operating and looking as it should.
Timber is a natural material, unlike man-made plastics such as uPVC, it changes state over long periods of time. By cleaning your sash windows regularly and addressing any issues as soon as they occur, you will prevent more major problems like wood rot from occurring. This extends the lifespan of your sash windows and helps them open and close easily.
Failing to look after your wooden sash windows can lead to wood rot, damaged or flaky paintwork, draughts and poor sound insulation. The moisture within dirt can get into the wooden frame which over time will weaken the structure. Also, paint can start to peel which will expose the wood to moisture and accelerate damage. Proper maintenance like cleaning and painting when needed will stop all of this from happening. Don’t worry, we’re going to teach you how you can avoid all of these things!
Cleaning sash windows can be difficult because of their unique design, but with the correct process it’s super easy to keep them looking clean. Here’s a step-by-step guide along with some tool and product recommendations:
Before cleaning, lay down some dust sheets to minimise the amount of cleaning up you need to do after. Move any furniture out of the way and cover window sills and the floor to stop drips. Also open the window so you can access both panes of glass.
Start by cleaning the inside of your sash windows. Use a soft cloth or sponge and wipe down the frame and window sills to remove any dust. For the glass, spray on a window cleaner such as Method and wipe it down in circular motions to avoid creating any streaks. Make sure to get into all of the corners and edges.
For the exterior, it can be challenging to reach certain areas, but sash windows are designed to make this easy. For higher windows you may need to use a ladder or a long cleaning tool such as a telescopic brush. Repeat the same cleaning process with glass cleaner for the outside panes. Be cautious when cleaning from the outside to ensure safety.
After cleaning the glass, lightly scrub the wooden frames with a soft brush and soapy water. Make sure not to use any harsh chemicals that could damage the timber. After cleaning, wipe the frame dry to stop any moisture from getting into the wood.
The tracks and pulleys are what make the window function smoothly. When they gather dust over time, it can affect the performance of the window. Use a hoover to clear any dirt or dust from the tracks when wipe them down with a damp cloth, drying them after.
Timber can be affected by weather over time, so it’s really important to protect it. Here are our favourite ways to maintain timber frames to protect against rot and damage:
Over time the paint on timber windows can fade or crack due to its constant exposure to the sun or rain. Repainting helps to protect the wood and maintain its appearance.
A new coat of paint not only improves the appearance of your sash windows but also acts as a protective barrier against the weather.
As well as paint, applying a protective coating to the timber is very important for long-term preservation, especially in areas prone to damp or harsh weather.
To keep your timber sash windows operating smoothly, regular lubrication and balancing are essential. Over long periods of time, the sash cords and pulleys that make the window open and close can wear out, making the sashes stiff or in the worst case permanently stuck. Lubricating these parts can prevent friction and make easy-to-operate windows.
As well as lubrication, balancing checks are crucial. When the sashes become unbalanced, they may stick or fail to stay open. You need to inspect the balance system and ensure that the weights are correctly aligned. Address these issues early to ensure the windows stay in top condition for years to come.
When cleaning timber sash windows, it’s important to avoid these common mistakes that could damage the wood or glass. One of the most frequent errors is using harsh chemicals or excessive water, both of which can cause significant damage to the timber. Instead, use mild cleaners specifically designed for wood and apply only as much moisture as necessary to avoid soaking the timber and causing rot.
Another common mistake is using abrasive cleaning tools on the glass or frames. Harsh scrubbing can scratch the glass and cause paint to peel or flake, which impacts the window’s appearance and also exposes the wood to moisture damage. Use soft cloths or sponges and gentle cleaning motions to preserve the paintwork and the glass.
When it comes to cleaning timber sash windows, homeowners often wonder whether it’s better to handle it themselves or hire professionals. DIY cleaning is an excellent option for regular maintenance, especially if you have easy access to both the interior and exterior of your windows. With the right tools and techniques, you can effectively clean and maintain your windows without professional help.
However, for larger properties or homes with hard-to-reach windows, hiring professional cleaners may be worth the investment. Professionals have the expertise, equipment, and access to specialised cleaning products to handle more complex maintenance tasks. If your windows need deep cleaning, repair, or extensive maintenance, calling in experts can save time and prevent costly damage. At Todi & Boys, we always recommend weighing your needs carefully to decide the best approach for your home.
