Our Team
Every ACI-TECH employee is individually licensed and accredited. Our crew brings decades of hands-on experience with residential and commercial remediation across the Delaware Valley.
Jack Helms
President & Owner
Jack founded ACI-TECH in 1995 and has led every major project since. He holds Pennsylvania asbestos contractor and lead contractor certifications and is personally on-site for inspections and abatement work throughout Chester, Delaware County, and the greater Philadelphia region. Clients who work directly with Jack consistently note his thoroughness and straightforward communication about what's safe and what isn't.
LinkedInStephen Helms
Field Supervisor
Stephen is ACI-TECH's lead field supervisor and holds PA L&I asbestos supervisor and lead abatement supervisor certifications, along with an EPA RRP certified renovator credential. He runs the day-to-day logistics on most ACI-TECH jobs — building containment, managing air monitoring during removal, overseeing HEPA decontamination, and coordinating air clearance with the independent hygienist. With over fifteen years working alongside Jack on Delaware County's older housing stock, he recognizes the material patterns in pre-1940 row homes — which pipe systems have been disturbed, where floor tile has been covered over, where joint compound from mid-century renovations is hiding — before the first sample comes back from the lab.

Our Services
Asbestos Remediation
Asbestos Remediation
Asbestos is a mineral fiber used widely in building construction for insulation and fire resistance. It appears in roofing shingles, ceiling and floor tiles, paper products, and cement materials.
When asbestos-containing materials are damaged or disturbed, microscopic fibers become airborne and can be inhaled, causing significant long-term health problems.

Lead Remediation
Lead Remediation
Lead paint was used in more than 38 million homes before its residential ban in 1978. EPA's Renovation, Repair and Painting (RRP) program trains contractors in lead-safe work practices to reduce contamination.

Mold Remediation
Mold Remediation
Mold can grow on virtually any organic substance where moisture and oxygen are present — wood, paper, carpet, and insulation are all common targets inside kitchens, bathrooms, and basements.
When excessive moisture accumulates and goes unaddressed, mold growth follows. Controlling indoor moisture is the key to preventing it.
