How Often Do Timber Windows Require Maintenance or Redecoration?
Timber windows are a fantastic investment for any home, offering timeless beauty, excellent insulation, and long-lasting durability. However, like any natural material, timber requires some level of maintenance to keep it in top condition. One of the most common questions we get at Grain Windows is: "How often do timber windows need maintenance or redecoration?"
The good news is that modern timber windows are designed to be low-maintenance, and with the right care, they can last for decades while continuing to look stunning. In this guide, we’ll break down everything you need to know about timber window maintenance, including repainting, resealing, and general upkeep.
How Long Do Timber Windows Last?
Properly maintained timber windows can last for 60 years or more, making them one of the most durable window options available. Thanks to advancements in timber treatments and protective coatings, modern wooden windows are far more resistant to the elements than older versions. You can read up about this more if your interested in timber at our friends over at FSC.
That said, regular inspections and occasional maintenance will help to ensure their longevity. The exact timeline for maintenance depends on factors such as:
The type of timber used
The climate and exposure to weather
The quality of the original finish
At Grain Windows, we use high-quality timber that has been treated to resist rot, swelling, and decay, ensuring minimal upkeep.
How Often Should Timber Windows Be Repainted?
One of the key aspects of timber window maintenance is redecoration, which includes repainting or re-staining the frames. Here’s what you need to know:
Factory-finished timber windows (like those we provide at Grain Windows) typically need repainting every 8–10 years. Hand-painted windows may require a fresh coat every 5–7 years, depending on their exposure to the elements. Stained timber windows may need reapplying every 3–5 years to maintain their protective finish.
For homes in coastal or high-exposure areas, windows may need repainting slightly more frequently. However, with Grain Windows' factory-applied microporous coatings, our windows are designed to last longer between repaints. There is a great website called Coating where you can find out further information about this We would also recommend getting us to do all the painting off site so when the windows or doors are installed everything has been done, no painting to be done, completely finished product which means they will last, compared if you painted the windows yourself.

What Other Maintenance Do Timber Windows Require?
While timber windows don’t require excessive upkeep, occasional maintenance will keep them looking and functioning at their best. Here’s what we recommend:
1. Annual Cleaning
Wipe down frames with a damp cloth and mild soapy water to remove dirt, dust, and debris.
Avoid harsh chemical cleaners that can damage the protective coatings.
2. Checking for Damage
Inspect the paint or stain for cracks, peeling, or bubbling—these are early signs that a repaint may be needed.
Look for signs of moisture ingress or rot (though this is rare with modern treated timber).
3. Lubricating Hinges and Locks
Moving parts such as hinges, locks, and sash cords should be lightly lubricated once a year to ensure smooth operation.
4. Reapplying Sealant
Over time, the sealant around the glass and joints may degrade. Check and reapply as needed to maintain a weather-tight seal.

Are Timber Windows More High-Maintenance Than uPVC or Aluminium?
One of the biggest myths about timber windows is that they require constant upkeep compared to uPVC or aluminium. The reality is that modern timber windows are built to last with minimal maintenance.
In fact, high-quality timber windows (like those from Grain Windows) often outperform uPVC in terms of lifespan and durability. While uPVC may only last 20-30 years before becoming brittle and discoloured, well-maintained timber windows can last for several generations.
