The Origin Story

Stop.Don't Overpay.

I grew up in glass. My father was a glazier and I was doing installs as a kid. I ran two factories. Along the way I found a way to drop the price — most companies charge way more than families can afford.

You want quieter, warmer windows. You don't want to spend $15,000 ripping out frames that work fine. We add a second pane to what you already have. No mess. One day, done.

Every quote is in plain numbers. No hidden extras. If we can't beat any real competitor quote by 30%, I'll say so. Stop. Don't overpay.

Transparent quoting. Fair pricing. 10-year warranty. That's the King promise. — Tas
