"Arrived when agreed, I got a quote on site. To fit a cat flap in my window. Returned to fit new cut glass, quickly, and fitted the cat flap for me the same time. Cleaned up afterwards. They have been in business for 100 years for a good reason. Thank you."

- Sam Williams

"We had a broken window (strained arms) repaired and another one cleaned and re-sealed. Barry arrived on time and was quick, polite and did a fantastic job. We've got him now to come back and replace two windows and door because we were that impressed with his/Altra Glass's work."

- Martin Pegler
