How long do wooden windows last

Wooden windows can last for centuries if they are properly maintained. Many old sash windows in historic buildings are still in excellent condition after 100-150 years or more of service.

Proper care and maintenance are key to ensuring that wooden sash windows have a long lifespan and last a lifetime.

However, wooden windows will require more maintenance than other types of windows, such as vinyl or aluminium.

Regular cleaning and checking for signs of damage to paintwork, rot or loose putty can help to extend the life of wooden windows significantly.

How often should I repaint and repair my wooden window?

You should expect to have to repaint or restain your wooden windows every 3-5 years, depending on how well your previous maintenance was done and how old your windows are.

It also depends on timber, hardwood wooden windows require a bit fewer repairs over time compared to softwood which rots very quickly if paintwork lets the moisture.

Same as compromised paintwork, loose or missing putty should also be removed and replaced as soon as possible with a new one to prevent moisture from entering the wood and causing rot.

When you compare the cost of refurbishment and replacement, you will see that it is almost always cheaper to refurbish your old wooden sash windows than to replace them with new ones. In addition, replacing your old wooden windows with new UPVC or aluminium windows will drastically reduce the value of your home and will change its character.

Which type of wood is better for windows in terms of durability and longevity?

When it comes to windows, there are two main types of timber that are used to make wooden windowshardwood and softwood.

Hardwood windows are generally considered to be more durable than softwood windows. This is because hardwoods are denser and harder, making them less susceptible to damage and wear and tear. Hardwoods also tend to be more rot-resistant than softwoods when exposed to moisture.

However, softwoods are often lighter in weight than hardwoods, making them easier to install. Softwoods also tend to be more affordable than hardwoods.

Some of the most popular softwoods used for windows include pine, spruce and fir. While hardwood windows are more durable and rot-resistant, they are also more expensive and harder to work with.

Windows on which side of the house will last longer?

Windows on the east and west sides of a building are more exposed to the heat from the sun than windows on the north and south sides.

As a result, sash windows on the east and west sides of the building will tend to degrade and get craked in paintwork and finally rot more quickly than those on the north and south sides.

There are several reasons why east and west-facing windows may degrade more quickly than those on other sides of a building.

First, the sun’s rays are more direct on these windows, causing the timber to heat up and expand more than on other sides.

This can lead to cracks in paintwork or stain and other damage over time.

Additionally, wind speeds are often higher on the east and west sides of a building, which can put additional stress on the windows.

Finally, rain and snow may also fall more heavily on these sides of a building, leading to further wear and tear. All of these factors can contribute to the need for more frequent repairs or replacement of east and west-facing windows.

How long do wooden double-glazed windows last?

It’s estimated that wooden double-glazed windows can last between 15 and 20 years; after this time, regular gas-filled double-glazing becomes less effective.

However, this will depend on a number of factors, such as the quality of the wood, the type of double glazing used, and how well the windows are maintained.

With proper care and maintenance, your wooden window frames can last 100 years.

How to extend the service life of your wooden windows

Here are a few tips to help extend the life of your windows:

  • Inspect your sash windows regularly for any signs of rot or soft spots. If you notice any cracks in the wood or broken putty, be sure to have them repaired as soon as possible.
  • Keep your wooden windows clean by washing them at least once a year.
  • You may also need to sand down the wood and apply a fresh coat of paint or varnish every few years to protect the wood from the elements.
  • Make sure that your windows are properly sealed around the window frame so it does not let the water in. Check the seals, and make sure it does not peel off around the frame.
  • If you live in an area with severe weather conditions, such as high winds or heavy snowfall, you can install storm shutters to protect your wooden windows.

You make sure that your wooden windows endure for a long time if you follow these guidelines.
