    Recently installed a new composite door and doorframe at my house. Excellent job, Old doorframe taken out and replaced without a mark to the surrounding paintwork. The New door is superb. Really solid, and as well as looking good, it is stopping all the drafts that used to come in round the old door.Thanks Guys A really good job professionally done and at a price that was a pleasant surprise.

Cloudy double glazing

We replace cloudy or misted units

A fogged up double glazed unit with condensation between the glass panes looks unsightly and is caused by a failed seal, compromising the thermal performance of the window. At CGS we can replace just the glazed unit rather than the entire window, saving money for our customers.
