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

Highly recommend the Sash Window Workshop
Customer Service
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
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.

Excellent work and a beautiful finished product!
Customer Service
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.)
