Timber Windows and Doors
Specialist manufacturer and installer of bespoke replacement timber windows and external doors. Our products include: timber sash windows, casement windows, French doors, front doors, back doors and bi-fold doors.

Our expert craftsmen manufacture all the bespoke joinery for our windows and doors in-house from our workshops in Berkshire, ensuring that our products are manufactured to the highest standards.

We offer repair and installation services in London and South England and a supply only service for new timber windows and doors across the UK.

Draught Proofing & Overhaul
Keep your home warm by draught proofing your timber windows. The Sash Window Workshop's draught proofing and overhaul service helps bring your windows into the 21st century, whilst retaining the aesthetic character and charm of your home.

We are timber-window specialists and have extensive experience draught-proofing timber windows across London and the South. We have worked on a range of listed buildings and period properties, including Georgian, Edwardian and Victorian homes.

At The Sash Window Workshop our draught proofing and overhaul service comprises:
  • Draught sealing
  • Minor repairs
  • Fitting new ironmongery and locks
If there are problems with your sash window dropping, we can replace the weights and cords to fix this as part of our draught proofing service.

Double Glazing
If your existing sash or casement windows are single glazed, cold and draughty but have solid timber frames, we can often fit new double glazing sashes into the existing frames to improve energy efficiency. When the new sashes are installed they will also be draught proofed.

The entire process through to completion has been first class and I am delighted with the quality of workmanship and the end result. The fitters/ installers have been excellent - they are hardworking, tidy, courteous and extremely helpful, and I could not have asked for a nicer professional team. Thank you!

I had repair work/draught-proofing done (and one replacement casement window installed) and am pleased with the result from start to finish. The team were hard-working, efficient and courteous throughout, did the work within the planned timescale and cleared up effectively as they went along.

The Sash Window Workshop Celebrates 25 Years

The Sash Window Workshop is this year celebrating 25 years of business. The company was established on the 11th February 1994 by Richard Dollar. Initially operating from a small converted pig shed in Ascot the company has grown and now operates from two workshops in Bracknell.

The company provides a range of bespoke timber window and door services, from complete replacement to draught proofing and overhaul. The loyal and dedicated staff, many of whom have served with the company for much of its 25 years, provide the backbone of the business.

To mark 25 years, the company invited some of their long-standing employees and commercial customers to celebrate at an exclusive private event at Westminster Abbey in London. Bracknell MP, Dr Phillip Lee, was also invited to visit The Sash Window Workshop’s office and workshop to see how the company has grown since his previous visit.

Managing Director and founder, Richard Dollar, comments on how the company’s growth has not always been easy:

“25 years have flown by, it’s been an interesting journey! Starting from nothing with a hand to mouth existence, through many ups and downs, to a very successful 2018 fitting and repairing £6.5 million of bespoke windows and doors.”

“We are very proud of our success which is based on giving our clients an exceptional product backed up with excellent customer service, all delivered by an outstanding team that has grown from 2 to 82 people. We look forward to continuing the journey over the next 25 years!”

Today, the majority of the company’s enquiries and orders come from previous customers and recommendations. With such successful growth over the last 25 years, The Sash Window Workshop is looking forward to more success over the next 25 years!
