About

The Sash Window Workshop specialise in manufacturing and installing traditional timber windows and doors in London and the south of England. Windows and doors are designed to improve energy efficiency, while retaining the traditional character.

Operating out of our factory in Berkshire, we manufacture bespoke sash windows, casement windows and external timber doors. If the frame is still in a good condition we can just replace the moving parts.

We also offer bespoke secondary glazing and a draught proofing service for timber windows.

Our aim is to deliver excellence at every opportunity and our experienced team of sales surveyors will ensure that you are provided with the solution that meets your needs.

We are proud that roughly half our orders come from existing customers and recommendations, highlighting our high quality products and excellent customer service.

Dealing with The Sash Window Workshop was a great customer experience from start to finish. We wanted the right look for the property and the initial visit helped ensure all the right options were chosen and in discussion it became clear that the right vendor was selected for our work. The installation was carried out by Joe over two days, and was very well done keeping the work area very tidy as he went along and spending a lot of time on the fit & detail using all the latest technology to ensure the windows were installed perfectly and aligned - which wasn't the case for the old windows that were taken out. The product just looks quality from inside and out, and being made from quality material with vendor guarantees gives us piece of mind. Overall highly recommended.

Sash Window Workshop installed 3 sets of garden (french) doors. The quality of the doors is very good. They were competitive on price. ( I got 3 quotes). The service from the staff was very good especially the installers. At one point the project hit an unexpected snag that required additional installers. The company had additional staff on site within an hour and the project continued on schedule. That sort of issue sets most contractors back by a week. All in all they struck me as a very experienced and well managed company

How refreshing - this really is a lovely company to deal with. Did what they said they would when the said they would, at the agreed price and in the agreed time scales. Charming workmen, who did the job efficiently; professionally; tidily; with good humour and to a high standard. I liked that the boss dropped in unannounced to check on the work. I also like that he obviously wasn’t surprised all good, as he clearly he knows his guys can be relied on to deliver. Really impressed. I was dreading getting these windows overhauled - it turned out to be a pleasure and a job well done.

We had new double glazed sash windows to replace old badly fitted single glazed units in 5 windows and a set of timber French doors. The company were professional, clean and tidy, the quality of the work and materials are excellent. I couldn't be happier with the result.

Extremely happy with the new wooden sash windows made and installed by the Sash Window Workshop. They were professional, punctual and courteous from start to finish, from the surveyor who measured up the windows to the fitters who installed them. The windows fit perfectly, look beautiful, cut down on noise and are exactly as promised. The fitters cleaned everything after they finished and worked quickly, efficiently and well. I am delighted that I chose this company. They were the more expensive of the three quotes I got beforehand but were worth every penny, with the work guaranteed for several decades.

Beautiful Sash Windows & Great Customer Service

The level of Customer Service I received from the Sash Window Workshop was outstanding throughout. Henry, their surveyor, created a positive initial impression and was able to provide us with what we wanted rather than what they could provide. This was a mix of double glazed sliding sash replacements, spiral hung sashes and complete new sliding sash windows, all supplied fully painted. I visited the factory and was shown around by Richard, the MD. He has clearly put much thought into creating the perfect sash window. He showed me the whole process and convinced me of the benefits and durability of the Accoya wood they use in the manufacture. They select only the finest glass and my new windows display this. The order and build process was handled smoothly and efficiently and the fitting team of Mark, Paul and Daniel skillfully replaced my 13 windows and a back door in a week. They left the house tidy and secure each night and by the end of the week my house was transformed with gleaming new windows. Slight damage to one sash caused by a protruding nail in an old frame was speedily made good. I would have no hesitation in recommending this excellent family run company to anyone considering renovating or replacing their sash windows.

Sash Window Workshop (and their sister company, London Window Painting Company) refurbished all our windows over a few weeks earlier this year. The office team managed the job very well, keeping us informed of everything, and the on-site team were really hard working and friendly people. This was particularly important as this kind of job (we found) rather takes over the house, so it was great to have such clarity and considerate behaviour. We're very happy with the refurbished windows, and highly recommend the company. (Re. price: we had several quotations, and found SWW were about average price for a recommended company. Bluntly, windows are expensive, but we feel SWW are fully justified.)
