Cap & Co was founded on a background in traditional joinery and a belief that windows and doors should be supplied, fitted, and finished properly.
“Before focusing on installation, I spent years manufacturing timber sash and casement windows and doors in a joinery workshop. Working hands-on with timber, glazing, and traditional detailing gave me a deep understanding of how quality windows and doors are made, not just how they are fitted.”
Peter Intasean
Every window and door is approached with care from the outset — thoughtfully specified, accurately measured, and fitted with attention to detail. We take the time to understand the building, the exposure, and how the window or door will be used day to day, ensuring the finished result is both practical and appropriate.
Our work is guided by a clear understanding of materials, construction, and long-term performance. The aim is simple: windows and doors that look right for the property, function as they should, and continue to do so long after installation.
Alongside new timber windows and doors, we also carry out repair and refurbishment work where existing joinery can be retained. This often provides a practical and cost-effective alternative to replacement while preserving the character of the building.
Where a low-maintenance solution is more suitable, we also supply and fit selected composite doors, offering clear advice on specification, performance, and suitability.
We offer a straightforward, dependable service built on clear communication and work done to a standard we’re happy to put our name to. No pressure, no unnecessary upselling — just careful work and considered advice from first conversation through to completion.
Projects are carried out across Oxfordshire, Northamptonshire, South West London and the surrounding areas, working with homeowners, builders, and property professionals alike.
