We had 2 large bay windows and one other replaced with double glazing which had to be in sympathy with what we already had. The overall experience was very professional. The carpenters were efficient, very clean and finished off the job perfectly.

They replaced an old sliding sash window with a doubled galzed sliding sash. Good quality wood and nice solid feel to the new window. The cost was £1090 plus VAT. The window was roughly 5 feet high by 3 feet wide.
