Acoustic timber sash windows that South West London homeowners trust, perfect for period homes near Wandsworth Common.


A Balham installation with bespoke detailing and a custom front door for improved warmth and noise reduction.
Featured Ranges in Our Balham Installation
The homeowners chose bespoke timber sliding sash windows from our traditional range, fitted with acoustic glass to reduce street noise. Each unit was crafted to match the original proportions, retaining the homeās traditional design while offering the performance of double-glazed sash windows. The new windows are built and sealed to improve internal comfort all year round.
To complement the sash windows, the owners selected a timber front door in a custom French green finish. The colour adds a subtle contrast while sitting comfortably within the style of the property. Like the windows, the door is fully sealed and fitted with modern locks and glazed detailing. This installation contributes to the homeās improved insulation and appearance, while preserving the look typical of doors across Balham and South West London.

Timber Sash Windows and Doors in South West London
This period family home in Balham ā in the area known locally as the āToast Rackā, a grid of streets lined with large Victorian and Edwardian homes near Wandsworth Common ā underwent a complete renovation. As part of the upgrade, the owners appointed us to replace all original single-glazed sliding sash windows and the front door.
The areaās architectural consistency and history give it a quiet conservation area feel, despite its proximity to Bellevue Roadās shops and cafes. Any upgrades require care to match the traditional design. The project aimed to retain the buildingās style while improving comfort and performance, and as a sash window company working across South West London, we supplied and installed sash windows to meet both goals.
Project Details & Challenges
The homeowners wanted to modernise the layout for family life, creating open-plan spaces across all floors. A key issue was the existing windows and doors ā single-glazed, draughty, and poor at blocking noise from nearby Bellevue Road. Rather than opting for sash window repair, they decided to replace their windows entirely.
After researching options, they chose timber sash windows with acoustic glass and a new front door, working with a sash window company that could deliver a complete, reliable sash window service.
Environmental Strengths
Every door and window installed in St Margaret’s Road was crafted from FSC-certified timber ā this ensures all wood has been sourced from responsibly managed forests, which help to preserve natural ecosystems and reduce environmental impact whilst still meeting quality demands. Choosing timber windows and doors from our range is an eco-conscious decision that can support the energy efficiency of your home in the long run.
Why Choose Our South West London Services
