About our adaptors
We use special fittings to attach new glass to your existing frame. Our frame reduces the glass size you see by about 40mm overall in height, and 20mm per side, approximately — that is the only visible change. No ripping out, no plastering, no mess.
This saves you thousands compared to full window replacement.

Tas Markou
Founder & Master Glazier
Tas grew up in glass. His father was a glazier and he was doing installs as a kid. Over 25+ years he built and ran two double glazing factories, with 40+ staff at their peak.
Along the way he found a way to drop the price — because most companies charge far more than families can afford. Today he runs King on one promise: transparent quoting, fair pricing, and a 10-year warranty on every job.
If we can't beat any genuine quote by 30%, I'll tell you straight. Stop. Don't overpay. — Tas
