Our work covers sash windows, casement windows, timber doors, and bespoke joinery across the full range of London’s housing stock – from Georgian terraces and Victorian townhouses to Edwardian semis and carefully considered contemporary homes.

About us
Period properties and careful specification
Working on period properties demands a different kind of attention. Proportions, profiles, and details that took decades to establish can be compromised quickly by the wrong choice of material, glazing, or installation method. We take that responsibility seriously.
Our team is experienced in working within the requirements that apply to listed buildings and conservation areas, where permissions, detailing, and the choice of material often call for a more considered specification. We are members of FENSA and Which? Trusted Traders, and our work comes with guarantee protection through Installsure. These are not just credentials – they reflect a consistent approach to carrying out the work properly.

Windows, doors and bespoke joinery
London homeowners come to us most often for sash windows, casement windows, timber doors and bespoke joinery, and those remain the natural centre of our work. Within those categories, some projects call for careful repair, some for replacement, some for performance upgrades, and some for something made specifically to suit the property.
For sash windows, that may mean anything from new sash windows to sash window repair, draught proofing and renovation, or new double glazed sashes where retaining the original box frame remains the better route.
For homes better suited to casement windows, we manufacture and install new timber casement windows with the same attention to proportion, finish, and long-term performance.
Our timber doors include the main types homeowners ask for most – front doors, French doors, bi-fold doors, and garden doors – while our bespoke doors and windows service is there for projects that fall outside the standard range.
Working across London
We work across London with an experienced team and a consistent focus on quality from the first survey through to installation and final checks. We are straightforward about what a project involves, clear about cost, and always more interested in recommending the right route for your property than the most extensive one.
If you are planning work on your windows or doors and would like practical advice from a London specialist, get in touch with the team to arrange a free, no-obligation survey.
