Replacement Glazing - Clearer, Warmer, Smarter Windows

Replacement glazing is the perfect solution when your double glazed units become misted, draughty or inefficient. You don’t always need new frames - just new sealed glass units.

At QHI, we supply and fit high-performance double and triple glazing into your existing UPVC or aluminium frames. It's faster, more affordable, and far less disruptive than a full window replacement.

We offer energy-efficient A-rated glass, decorative options, toughened safety glazing and sound-reducing units - all installed by our experienced local team. It's a simple upgrade that makes a big difference.
