How can we help owners of sash windows in London

Sash windows are our area of expertise. We’ve spent years creating and installing beautiful bespoke windows within homes throughout London and we’re confident that our work will enhance the unique character of your property. All our sash windows are handmade within our UK-based workshop by our team of expert carpenters, giving you and your home the benefit of high quality British craftmanship.

We offer three distinct sash window services:

  • Complete renewal
    This service provides a comprehensive overhaul of your windows, replacing them entirely and installing new box frames and double-glazed sashes in their place. Our team members have worked extensively within period properties, listed buildings, and conservation areas and understand exactly how to overcome the challenges that are associated with these settings.
  • Sash replacement
    We can install new sash windows within your existing box frames, providing the benefit of double glazing with less disruption than a full window replacement. Our team will fully draught seal your new sash windows, making sure that your home receives a high quality, energy efficient upgrade. It’s no wonder that this is our most popular sash window service!
  • Draught seal and overhaul
    We can maintain and repair your existing sashes and frames, incorporating modern materials and technological developments without altering the appearance of your windows. Our team can carry out a wide range of adjustments and improvements, covering everything from rebalancing individual sashes through to draught proofing.

What makes sash windows an excellent choice for London homes?

Distinctive appearance
The classic, timeless appearance of sash windows makes them an ideal fit for a wide range of different properties and styles. Whether you’re hoping to preserve the appearance of your Georgian home or you’d like to invest in a design feature that will enhance a modern build, carefully designed sash windows make a worthwhile addition to any property. Plus, as well as being eye catching, the slim profile of these windows will allow plenty of natural light into your home.

Practical benefits
Sash windows are easy to use and live with. They can be finely adjusted to create a gap at the top or bottom of the window, allowing fresh air to ventilate the room while also preventing rain from entering. Our bespoke sashes can also incorporate acoustic glass to reduce the impact of external noise, making them an ideal solution to the hustle and bustle of London’s streets.

Extensive lifespan
Owners of high-quality sash windows can expect them to last far longer than a uPVC alternative – more than a hundred years in some cases! As the sashes are hung evenly from their top corners, they don’t experience the same stresses as windows that are supported by a hinge on their side. This makes them much less likely to distort under their own weight.
