Three decades of one thing,done relentlessly well.
Glas Tek has been repairing windshields across St. Louis and St. Charles County since 1995 — an affordable, structural alternative to full glass replacement, performed by technicians who do nothing else.
Started in 1995 with one stubborn idea.
Replacing a windshield is expensive, slow, and — in most cases — completely unnecessary. Glas Tek opened in St. Louis with the goal of offering a real alternative: a precise, structural repair that costs a fraction of a replacement and keeps the original factory seal intact.
Over three decades we've tested every resin, tool, and technique on the market to find what actually delivers — for everything from rideshare fleets to the family minivan. We don't replace windshields. We don't detail cars. We don't tint windows. We repair glass, and we do it all day.
The result is a failure rate of one in five hundred — the lowest in the industry — backed by a 100% money-back lifetime guarantee.
We do more repairs in a week than most shops do in a month.
At a full-service auto glass shop, a technician might complete 3–5 windshield repairs in a typical week. Our techs complete 40–60. Every week. Year after year. That repetition is what separates a "good enough" fix from one you can't even find when we leave.
We don't moonlight as a replacement shop or a detailer. Repair is the whole job.
More repairs in a month than most techs do in a quarter — by an order of magnitude.

Three decades of testing every resin and injector to find what actually performs.
Credentials you can actually look up.
