Timber sash windows bring a unique look at any property with period authenticity. These sash windows are perfect if you are renovating an older home in a conservation area, or you are planning on improving the glazing within a listed building. Sash windows are made out of two movable sashes and one sits in front of the other. Some windows will have decorative features. We can install windows that benefit from exceptional security, as well as thermal and acoustic performance.

We can also supply and install casement windows. These windows are attached to the frame on one side only and are either used individually or in a pair. We design our bespoke casement windows with performance and style in mind. See our gallery.

We also supply and install a great range of uPVC sash windows. These windows can provide a more cost-effective alternative to timber windows, whilst also offering a classic look, excellent energy efficiency, and superior security. These windows are also very low maintenance, so they will only need a wipe of a cloth to keep them looking good. uPVC sash windows are extremely durable and are designed to withstand even the harshest weather.

SW12 sash windows restoration and draught-proofing

Traditional sash windows in Balham can look fantastic but they will require careful maintenance to keep them in good condition. If you have noticed that your vertical sliders are draughty and you have large energy bills, draught proofing will make them more efficient. We use specialist sealing to transform their ability to retain heat, whilst always retaining the aesthetic character and charm of the window.

Overhaul services that we complete include:

  • Draught sealing
  • Replacing the weights and cords
  • Repairs to damaged frames and glazing
  • Repairing or fitting new locks

Secondary glazing for your sliding sash windows in Balham

We can provide made to measure secondary glazing that will enhance the performance of your windows, whilst never affecting the charm of their appearance. Secondary glazing can provide a wide range of benefits for sash windows in Balham in both domestic and commercial properties. It can provide high-performance acoustic insulation, improved energy efficiency, remove issues with condensation, and improve security.

Secondary glazing is different from double or triple glazing because it fits an additional window behind the existing sash window or casement window. Whatever the style of your windows, our expert team can adapt the secondary glazing to suit.

Sash windows make a fantastic addition to any property and there are many reasons that timber windows continue to be hugely popular.

Authentic Appearance

Timber windows and doors ensure your period property retains its original charm, by replicating both the design and material of the original windows. Timber windows are often a requirement for listed building renovations.

Long-lasting and durable

Unlike other materials that may discolour and degrade over time, timber can be easily maintained with a new coat of paint or staining. Despite many people thinking that timber requires intensive maintenance, this is not the case. Maintaining your timber sash windows is easier than you think.

Energy efficient

Timber is a naturally insulating material and can provide comfortable temperatures. Many people assume that timber windows cannot be double glazed, but this is not the case. They will ensure that your property remains warm in winter and cool in summer.


Timber is a sustainable material and the eco-friendliest choice when it comes to window frames.
