About Us

Quality you can see.
Calibration you can trust.

At Professional Glass Installers (PGI), we believe your car should leave our shop better than it arrived; safer, cleaner, and truly taken care of. For more than 35 years, our name has been tied to quality glass work in Lawrence and the surrounding communities.

Our Story: A 35+ Year Local Legacy

PGI started as a small, family-run glass shop built from scratch by Jason’s father-in-law over three decades ago. He spent years earning the trust of local drivers, dealerships, and body shops one windshield at a time.

In 2022, long-time installer Jason Colvin and his wife Jamie bought the business, carrying that legacy forward while modernizing how the shop operates. Today, PGI blends old-school craftsmanship with up-to-date technology like in-house ADAS calibration and professional window tinting—without losing the family feel that built the company in the first place.

We’re still the same local shop Lawrence has known for decades—just with more ways to keep you and your vehicle safe.

What We Stand For

Your car leaves better than it arrived.

That’s our core promise, and it shows up in how we work every single day.

  • Quality over speed. We move efficiently, but we don’t rush installs. We’d rather take the extra time to do it right than cut corners to shave a few minutes.

  • Clean, careful workmanship. We treat every vehicle like it’s our own—interiors protected, trim and moldings handled with care, and your car coming back to you cleaner than it showed up.

  • Lifetime workmanship warranty. If a windshield we installed ever leaks, or you’re unhappy with our craftsmanship, we’ll make it right. We even work with our glass suppliers when a piece of glass is defective, and we cover the labor to replace it.

  • Local, honest pricing. Dealerships and shops trust us because they know we’re fair. We know our bottom dollar and don’t “gouge” just because we can.

We’re not trying to be the fastest. We’re trying to be the most trusted.

Trusted by Dealerships, Loved by Locals

Nearly every major dealership in town relies on PGI. Many simply drop cars off without even asking for a quote—because they already trust the quality, pricing, and consistency they’ll get from our team.

That same level of service is what every walk-in customer receives. We’re proud to maintain around a 4.9 Google rating with 160+ reviews, with new customers often telling us they chose PGI because of our reputation online.

Whether you’re:

  • A local driver with a cracked windshield,

  • A KU student who just discovered rock chips are a Kansas rite of passage, or

  • A dealership, body shop, or rental agency that needs a reliable glass partner,

you get the same careful install, accurate calibration, and honest communication.

Advanced Services, Done the Right Way

Modern windshields are more than just glass; they’re packed with safety systems that rely on properly calibrated cameras and sensors.

At PGI, most windshield replacements include in-house ADAS calibration, often paired with the install on the same visit. On roughly 85–90% of the vehicles we service, calibration is part of the job, and it’s one of the most valuable ways we help keep you safe on the road.

Our core services include:

  • Windshield Replacement & Repair
    From small rock chips to full replacements, our techs have done thousands of installs across virtually every make and model.

  • ADAS Calibration
    Using proper calibration procedures and equipment, we reset your vehicle’s cameras and sensors after replacement so lane-keep assist, collision warning, and related features work as designed.

  • Window Tinting & Brow Strips
    From full-vehicle tint to quick brow strips across the top of your windshield, we can add comfort, privacy, and style while your vehicle is already here for glass work.

  • Heavy Equipment & Construction Glass
    With major construction projects and bypass work in and around Lawrence, more contractors are turning to PGI for glass on graders, track hoes, and other heavy equipment. If it has glass and it works for a living, we’re interested in keeping it safe and productive.
