The Original Box Sash Window Company renovated my sash window boxes, and replaced the sashes windows with similar Georgian style double glazed units in keeping with the Conservation Area conditions. The windows are very high standard, well-fitting and draught-free. Such a difference, and so quiet..

Good quality work, and excellent outcome in the end, but needed a little push to meet the required finish standard at one point..

I had a Victorian bow window replaced. The work was first class. The installer was punctual, polite and professional. I wish all other traders would be like him.

Had downstairs bay window and 2 upstairs sash windows replaced. Workman turned up on time everyday, dust sheeted absolutely everything and did a complete clear-up at the end of each day. The quality of these windows and skill of the installer cannot be faulted. They only use their own installers, who are highly skilled and do a faultless job. The windows themselves are UK made, of the highest specification and look and operate fantastically. The company do it right and would recommend their work.

Envoygate installed a new window in our bedroom at the start of the year. We got in touch with them after they had carried out some work for us before. They are clean, reliable and the materials they use are of high quality. I would recommend their services as they are very professional in all respects.
