Gen X Environmental is a Denver-based testing and consulting firm led by founder John Peralta, a true Gen X’er with a Boomer-level work ethic and a people-first mindset.

We help homeowners, contractors, restoration teams, and real estate professionals make confident decisions with certified asbestos, mold, and lead testing—from bulk and air samples to spill inspections, delineation, and clearance guidance.

John grew up outdoors (and still sneaks in dirt-bike rides), but what drives him today is service: show up, listen, do the work right, and explain the results clearly so your project stays on track.

We value ethics, relationships, and reliability—meaning careful sampling, accredited lab analysis, and straightforward communication you can act on.

If you need answers, a timeline, and a steady hand, Gen X Environmental is here to help you move forward safely and efficiently.
