Why choose Timber Sliding Sash Windows?

There are multiple benefits to choosing timber sash windows, including:

  • We can replicate traditional timber window designs to produce wooden sash windows that meet the requirements for listed buildings or homes in conservation areas


  • You can choose from hardwood or durable softwood sash windows depending on your preference


  • Our modern timber sliding sash windows have all the benefits of the latest glazing, sound reduction and security technology, but with a traditional classic look


  • Windows that are highly weather rated, keeping your home dry and warmer during colder months


  • Sustainable materials are used, reducing the negative environmental impact in the manufacture and lifecycle of our wooden sash windows


  • We offer a 10-year warranty on our timber sliding sash windows because we are confident in their durability and the quality of materials we use.

Bringing the best of both worlds, our timber sash windows are manufactured sustainably, designed to suit your property and budget and built to last.

For period properties, specially selected hard or softwood sliding sash windows can be the perfect choice for those wanting to keep all of the character and charm of the original windows, without compromising on the practicalities such as double-glazing, modern mechanisms and security features. 

Replacing your Timber Sash Windows

Original sash windows are beautiful, but depending on when the property was built, they can have a wide range of different issues. The old windows are usually single-glazed and offer very limited protection from weather, draughts and noise. They may be damaged or rotten and the mechanism might not be functioning as it should. Some of these windows can be anywhere from decades to centuries old, so will need replacing at some point.

Replacing timber sash windows can be a daunting prospect for homeowners of period properties, and even more so in homes that are in conservation areas or are listed. Maintaining a traditional look is usually a high priority, so many people worry that new timber sash windows won’t live up to this. However, our timber sliding sash windows are designed to only enhance the property’s period features and style, whilst also bringing modern conveniences and features that are functional as well as beautiful.

The process of replacing wooden sash windows includes:

The design & manufacture phase – We design new timber sash windows according to your specifications and to suit the period of the property. We then manufacture the windows to incorporate all the features you need, using the sustainable wood of your choice.

The installation phase – Our team of specialist installers ensure that the installation of the new timber sash windows is completed to the highest possible standards.

The aftercare phase – We are so confident in the design, manufacture and installation of our timber sash windows that we offer a 10-year warranty. If you have any questions after the installation then we are available and happy to help.

Timber Sash Windows FAQs

What Manchester Window Factory doesn’t know about windows isn’t worth knowing, so if your question isn’t answered below, our family-run business is here to help.

Real wood sash windows can be fitted in virtually any home, but are most often used in period properties to replace existing traditional sash windows that are damaged or simply need upgrading to better suit modern living. 

If your property currently has wooden sash windows that need replacing and is in a conservation area or is a listed building, it’s very likely that they will need to be replaced with high quality timber sash windows that replicate the original design and style very closely in order to meet the required standards.

Timber sash windows are designed to last a long time as long as they are maintained regularly. While there is no set time-frame on how long sash windows should last before they need to be replaced, it should be many decades with the right maintenance i.e. painting or treating the wood every few years to protect it.

Our wooden sash windows come with a 10-year warranty and we believe that they can last for a lifetime if they are regularly maintained and checked. 

Traditional sash windows often have a latch on the inside to prevent them from being opened from the outside and may have ‘stops’ fitted which prevent the window opening fully. However, many original timber sash windows don’t have the same high levels of security that modern windows do, which can be a concern to homeowners. 

Our new timber sash windows incorporate insurance-standard security locks and this can be further enhanced with high-security glazing, which means they can be every bit as secure as other types of window, if not more. 

Sometimes period properties have had UPVC windows fitted at some point that you may now want to restore to the more traditional timber sash windows. It is possible to return this type of property to its former glory with durable wooden sash windows, with the help of a timber window specialist.
