“Flawless from start to finish!”
Redhill Double Glazing replaced our old single-pane windows with modern double glazing, and the difference is incredible — warmer rooms and no condensation. The team arrived on time, worked cleanly, and left everything spotless.

“Quick and professional after our window broke”
We had a cracked living room window late at night — they came out the same evening to board it up and replaced the glass the next day. Couldn’t ask for better service.
– James R., Reigate
“Perfect cat flap installation!”
We wanted a cat flap in our double-glazed door, and these guys handled it perfectly — neat finish, safe glass cutting, and a happy cat! Highly recommend their work.
– Emily & Tom, Merstham
