a traditional sash window company in london

Our Business Background


Bespoke traditional sash windows and doors are the heart of what we do. We are a FENSA Approved company wich specialises in all types of bespoke Winows, Doors, Conservatories and Architectural joinery as well as Sash Window & Double Glazing repairs.


Traditional Sash Windows.co.uk is a traditional family owned and professionally managed business that has been established since 1983. We are based in South London and currently carry out work all over London including the Suburbs. 



Our Business Style


Thanks to our many years of experience in providing versatile solutions in timber construction, technically demanding installations, project planning and realisation as well as outstanding ecological quality, we are in a position to offer you a truly exceptional level of craftsmanship.


What’s more is our sash window company isn't like many franchise based companies and can therefore invest more time with our customers due to not having such large operating costs as many franchise companies do.


Because we are an individual based company, for a great amount of our work we rely solely on Customer Recommendations, and for that reason we like to develop a friendly relationship with our customers and help them through every step of the decision making process as this can be at times quite a worry for customers who don’t necessarily know what’s best in terms of energy efficiency, traditional style (London Bourogh Regulations) and Value for money.

“We had Traditional Sash Windows replace eight sash windows in July 2013.  We were thoroughly delighted with the workmanship.  Since we were running to a tight schedule and organizing the work from our home in The Netherlands, we anticipated some problems.  These never materialized.  Alan and John did a fantastic job.  The windows themselves are,,,


Mrs Pamela White,


"We noticed the difference immediately"

"We are really delighted with our beautiful new double-glazed sash windows. We decided to have the work done after the bitterly cold winter last year.
