sash windows customers…

Simon Hampton

We needed three sash sliding windows replaced in our Georgian house and have been delighted with the work carried out by William Richards. All staff were friendly, professional, and capable and we will certainly use them again.

Susan Jenkinson

Ricardo and Paul were completely charming and very professional great ambassadors for an excellent company who have done a wonderful job — I highly recommend this company.

Jon Bourne

We've just had seven sash windows refurbished in our home - what a professional and helpful company. From start to finish, they were really responsive, creating completely new windows or salvaging existing frames. They kept in touch with us during the manufacturing process as our lead time was sensitive to other work.

Vicky Nash

Just had 8 enormous Victorian sliding sash windows replicated in Slim line double glazing by William Richards. Had 5 companies in (visiting 3 of their workshops) to discuss options & quote. Chose this small family business and so glad I did in every respect.

Frequently Asked Sliding
Sash Windows Questions

What is a sliding sash window?

If we haven’t answered this question then I should make myself redundant. A sliding sash window is a window that opens vertically, therefore realistically all sash windows are sliding. Unless yu nail it shut! We don’t recommend this.

What is the wait time on your sliding sash windows?

How long is a piece of string? It totally depends on the spec of the job. Do you need two or twenty? Can we use your existing frames or need to build new ones? The average job time is listed in our stats section above.

Are sliding sash windows draught-proof

You bet. All of our sash windows are draught-proof as standard. The general impression when someone thinks about sash windows is that of a draughty old spooky house, when in reality our sash windows are modern, contemporary and weather resistant.
