Try Diamond Construction http://www.diamondconstructions.com/page,p4. They have just redone all the windows in our house and they are beautiful. We couldn't be happier with them and they weren't too expensive

I have just had 3 sash windows replaced and would highly recommend www.mtm-herman-joinery.co.uk They have provided a bespoke service to match exactly the design of my existing windows and replaced them with a fantastic double glazed version. Excellent craftsmenship, reasonably priced. Very happy customer.

Many thanks for your recommendations!

We used the Sash Window Company, based in Guildford. They do lots of work in SW London and are v good.

We use MTM Herman who were recommended to us. So far they have replaced two sash windows - one entirely including the box frame as it was rotten and the other just the sashes and have refurbished the frames.

They are very reliable, clean, trustworthy and fairly priced. Their website is www.mtm-herman-joinery.co.uk. Our contact is Mirek 07885 551724.

We need to replace our sash windows and would really value any recommendations of a builder or company who could do this at a reasonable price. Many thanks!
