What our clients say
Wooden Sash Window
I am absolutely delighted with the work of Gary and the team and I definitely recommend them. The work was completed on time, on budget and to an exceptionally high standard. They specialize in double glazing period windows in listed buildings and conservation areas and use high spec materials that both satisfy even the most stringent conservation area planning regulations and provide massively improved thermal efficiency. Yet surprisingly, their prices compare favourably with other firms.

Gary and his team did a brilliant job restoring and replacing my old window with double glazed sashes. Right from the start Gary was quick to reply to my emails, easy to deal with and came straight over to look at the job. Richard and Tom carried out the work and completed the job without running over. The workmanship is excellent, the result is better than I could have expected. I will definitely be using Gary again. Thanks again!

Had two wooden sash windows replaced, and everything was of the highest quality from the initial advice to the timely and precise execution of the job. Couldn’t have been better, and I give Gary and team my highest recommendations. Excellent.

Gary and his team did an amazing job. The service was so quick and the workmanship was excellent. Gary was really knowledgable and listened to our needs and requirements and gave us a great price. We needed the work done quick as our baby was due and Gary managed to accommodate us which we appreciated. Had so many lovely comments from neighbours. Will be using them again soon!
Gary Baker and his company/collaborators/partners are just the best people you could ever choose for installing and replacing your windows. They are simply exceptional. In only 4 days they replaced my bay window and bedroom window, replacing the rotten wood and installing a brand new hardwood window. The draught-excluder technology is fantastic, the double glazed and sound-proof glass are incredible. My flat won’t be the same as before. Guys thank you!

A sash window or hung sash window is made of one or more movable panels, or “sashes”, that form a frame to hold panes of glass, which are often separated from other panes (or “lights”) by glazing bars, also known as muntins in the US (moulded strips of wood). Although any window with this style […]
