Sash Window Replacements South East London

We can replace your sash windows in South East London if a repair is not an option

High quality sash windows installed by skilled carpenters

Replacing or re-instating box sash windows is often the only option if the windows are beyond repair or if you simply want double glazing. New sash window replacements are the only option when the original windows have been replaced with UPVC double glazing or other types of windows and doors.

In nearly every situation where the windows are put back to replicate the original features the value of the property is increased by more than the cost of replacing the windows.


We only employ experienced joiners to manufacture your new sash windows to ensure high quality and ultimately complete satisfaction on completion of the work.

The Wood

As standard all new joinery is made in joinery grade softwood; however we also supply BC pine, Mahogany and Accoya windows.

The Glass

All new glass single and double glazed is fitted to comply with current building regulations. All single glazed replacement sashes will be glazed with 4mm glass, clear or patterned. Double glazed units will be either 16mm(4.8.4) or 24mm (4.16.4) depending on the thickness of new windows and both come gas filled. The u-value of the 16mm units are 1.7 W/m2K. The U-value of the 24mm units are 1.2 W/m2K.

The Paint

All new windows will come fully decorated. We will decorate your windows to your desired finish (gloss, stain, white, black etc) All joinery is spray painted using Johnstone’s aqua system white gloss (unless specified).

The Furniture

Key locks are provided as standard, along with sash lifts and sash pulls. Restrictors are also available. Choice of polished brass and satin chrome as standard but full catalogue is available for alternatives.
