We design our wooden sash windows to bring a touch of luxury and period charm to your home. They replicate the style of windows from the Victorian and Georgian era. Each window is custom-made with your choice of frame, glass, and configuration. You can choose from six painted finishes or three natural wood stains. Additionally, you can add decorative glass, bars, and furniture.

We only use timber from FSC®-certified and controlled sources. By choosing our timber sliding sash windows, you are supporting responsible management of the world's forests. You can choose pressure-preserved softwood or hardwood frames for added durability. If you want to replace wooden sash windows or add elegance to your new home, they are a valuable investment.

Our double glazed wooden sash windows have an A-rating for energy efficiency. Wood is a good insulator, so it reduces the transfer of cold or heat through the frame. Our double glazing has low emissivity glass panes. It also has inert argon gas between the panes, which further reduces heat loss.

Our timber sash windows have thick weather seals around each window sash, inside and outside. They also have compression seals between the sashes. When you close the windows, they create a tight seal to prevent drafts and keep heat inside.

Old sash windows had condensation because the glass was cold and single glazed. The excess moisture caused rot and decay. Our new wooden windows reduce condensation by keeping out the cold air. This helps your windows last longer.

We build each timber sash window with strong security features. These features keep intruders out and protect your belongings.

  • There are two rotating cam locks in the middle. You can operate these locks with a key. The top and bottom sashes lock together.
  • Lockable lift restrictors that stop the window at a 100mm wide opening.

Wooden sliding sash windows come with many guarantees. They show that we install high-quality products. Here are the main guarantees and accreditations:

  • We offer a 10-year guarantee on the timber sash frames. Not all window companies offer this, so make sure to do your research. The guarantee covers the cost of a partial or complete repair of your windows.
  • 10-year guarantee on the sealed glass unit. The guarantee covers a "blow out". This is where the glass seal breaks and condensation appears between the panes.
  • 30-year anti-rot and fungal guarantee.
  • 10-year guarantee on window furniture, including handles, cam locks and sash pulls.
  • 1 to 10-year guarantee on surface finish, depending on your window and the finish you choose.


  • We are FENSA and Glass and Glazing Federation (GGF) accredited. We install our wooden casement windows in compliance with the latest building regulations.
  • The FSC® label means that materials used for our wooden sash windows have been responsibly sourced.

Our wooden sash windows are perfect for period properties or adding charm to your home. Our frames are precision-machined for a smooth finish. We make your wooden double glazed sash made to measure, so they fit your home perfectly.

  • Min height 838mm
  • Min width 1445mm
  • Max height overall frame 3344m

We Make our Timber Sash Windows in the UK

We create double glazed timber sash windows in the UK using traditional methods and new techniques. First, we choose good timber. Skilled craftspeople then layer the wood in opposite directions to make it strong. Next, we sand and finish the windows with a protective coating. This coating makes the windows last longer. After we check the quality, we send your order to your local team. They will install the windows for you.

Your Questions Answered

Are wooden sash windows worth it?

You can't beat the look and feel or real wood. This makes wooden sash windows a smart investment for your home. They do need more regular maintenance than uPVC, like repainting or resealing. But unlike uPVC, you can always paint them a new colour. With proper care, wooden sliding sash windows can last for decades.

How long do wooden sash windows last?

Sash windows made of hardwood with a weather-resistant finish will last decades. Softwood windows usually don't last as long. But this also depends on the finish and wood treatment. To extend the lifespan of your windows, take good care of them.

Are wooden sash windows draughty?

Many people think of old Georgian houses when they see wooden sash windows. They imagine windows that are single glazed and rattle in the wind. But today, wooden sash windows are double glazed and custom-made. They also have weather seals to keep out draughts and bad weather.

What is the best timber for sliding sash windows?

The type of wood that works best for sash windows depends on the window's direction and the local weather. If your windows get a lot of sun or driving rain, consider hardwood for your timber sash windows. If your home doesn't experience harsh weather, you might want to consider softwood. You can talk this through with a professional before going ahead.

How much do wooden double glazed sash windows cost?

The price of wooden double glazed sash windows varies based on their size, type of wood, and how they open. Hardwoods are usually pricier than softwoods, but there are some exceptions. You can expect to pay more for larger windows.
