What is Replacement Double Glazed Units?

A replacement unit is much better than a simple repair. When a double-glazing unit is unrepairable then its time for a new unit which replaces the old one. Whether it’s a upvc door or aluminium door, double glazed window or alu window its known as a unit. The benefit of replacement glazing is, you as a home or office owner will gain a brand new warranty which lasts a minimum of 10 years with upvc and 15 years for Aluminium and means total ‘’peace of mind’’ for you (the buyer). Another replacement type is from pvcu to aluminium which could be down to security reasons or even insurance requirements but at the end of the day, you have total peace of mind with Daylight Glazing.

Daylight Glazings replaced an external door with a brand new UPVC door and frame. They intially came for a... consultation to assess the job and we received a call, followed by an email regarding the very farely priced quote (we'd been searching for months for a decent price!). They were extremely polite, professional and skilled at their jobs and got it all down within a couple of hours. I'd definitely reccommend them to people and wouldn't hesitate to use them again!read more
