Full timber sash window replacement in SW13 using bespoke units made to match the original design.
High-performing sash window installation with improved acoustic control and period-accurate detailing.
Featured Ranges in Our Barnes Installation
13 timber sash windows were installed throughout the property, specified in a one-over-one design to reflect the original layout. Each box sash was finished in clean white, in keeping with the neighbouring properties and in line with the area’s planning requirements.
While visually traditional, the new sash windows offer modern performance benefits, including sealed units and improved acoustic and draught control.
Three flush-fit timber casement windows were installed in the first-floor bay. Each frame was built to match the original profile and fitted precisely to the angles of the bay, ensuring a clean and accurate finish. The decorative detailing below the window was retained. The casement windows were sealed and finished to a high standard, with particular care taken to allow for natural movement in the timber.
This approach improves weather resistance and contributes to the overall energy efficiency of the home. The result is a high-quality sash window replacement that stays true to the property’s original appearance.
Timber Sash and Casement Windows in Barnes
This six-bedroom property in Barnes, South West London, forms part of a residential street known for its period houses and proximity to the river. The new owners began their renovation by addressing the windows, which were draughty, noisy, and beyond repair.
We were instructed to carry out a full replacement. We supplied and installed thirteen timber sash windows and three flush-fit timber casements, maintaining the original appearance while improving performance across the property.
Project Details & Challenges
The existing windows were in poor condition, with visible wear, gaps around the frames and little acoustic protection from the street. The owners ruled out sash window repairs early on and opted for full replacement. The priority was to retain the property’s original appearance while addressing issues with noise, draughts, and heat loss.
We recommended a timber sash window replacement across the property to match the original design.
Craftsmanship & Materials
All units were manufactured from engineered timber at our Cornwall facility using sustainably sourced redwood. The high-performing finish includes a full four-stage coating system and comes with a 30-year guarantee against rot and decay. This approach allows us to offer durable, long-lasting products at a competitive price without compromising on quality.
