Great service!! Well priced and good communication. Would recommend. +++
The guys were great. They were very efficient and friendly. They arrived when they said they would and did a sterling job. I can't believe how quiet the house is now the windows have new hinges... and no howling gale!
Brilliant. Within 1.5hours of calling them. The job was done, good work, pleasant friendly men. Definitely to be recommended.
After calling Nick at short notice this morning, he responded very quickly to our damaged window. Many thanks Nick for your speedy response and excellent service
Great job, the guy's installed 5 upstairs windows. They turned up when they said they would. worked very professionally and cleaned up after themselves, what more can you ask.
Called CGS glazing at 9am for an emergency in Blackburn. Nick came out from Burnley and had it fixed by 10am. Price was reasonable. I would highly recommend.
An absolutely brilliant firm, the guys were exceptional with their work and the prices were great value for money. So good in fact I have requested two installs from them and will be lining up a 3rd in the new year. Fantastic!
Though a small repair, the work was carried out professionally and the service provided by all was friendly and to be fully recommended.to new customer.
Great service from initial quotation to installation. Highly recommended with competitive pricing. Will use again.

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, potentially saving you hundreds of pounds.
