What We Do

Services

Emergency repairs, scheduled PM, or long-term contracts — we cover mechanical, electrical, chemical, and water treatment across every wash format.

Preventive Maintenance

Scheduled PM built around your equipment and your hours. We cover mechanical, electrical, and chemical — so small issues never become shutdowns.

Equipment Diagnostics

We trace faults to the root cause — not just the symptom. VFDs, controllers, photo eyes, pump systems. No parts swapped on a guess.

Pump & Motor Repair

Rebuilds and repairs on Wanner Hydra-Cell, CAT, EBARA, and triplex pumps. We carry common rebuild kits and keep turnaround tight.

VFD & Electrical Service

3-phase diagnostics and drive programming for Allen-Bradley, Mitsubishi, and Siemens VFDs. Fault codes, motor commissioning, MCC panels.

Water Treatment & RO

Softener service, RO membrane maintenance, and TDS management. We eliminate spotting complaints and keep water costs under control.

Consulting & Commissioning

New equipment commissioning, operator training, and honest technical advice — from someone who's been on both sides of the wash.

Our Difference

Why Terlak Wash Services

We're technicians first — not a distributor with a service department. That changes everything.

01

Independent & Unbiased

No manufacturer quotas, no upsell pressure. We tell you what's wrong and fix it — whether that's a $12 relay or a full rebuild.

02

True Tunnel Expertise

A decade of hands-on experience across mechanical, electrical, chemical, and control systems — simultaneously. That combination is rare.

03

Fast Response, Local

Based in Westmont, in the Chicagoland market. No regional dispatch, no call queue. When you're down, we're moving.

04

Transparent Pricing

Quotes before work starts, every time. Hourly for diagnostics, flat-rate for PM. No surprise invoices.

Self-Serve & In-Bay Automatics

Upgrades & New Installs

New Equipment & LED Lighting

We help operators source, install, and commission new equipment — and handle LED lighting upgrades that modernize your site and cut energy costs.

LED tunnel and bay lighting is one of the highest-ROI upgrades a wash operator can make. Lower energy consumption, longer fixture life, and a brighter wash environment translate directly to customer perception and return visits. A dark, dated tunnel hurts ticket sales. A well-lit one sells upgrades.

Because we're independent, we help you find the right product for your site — not whatever's easiest to push. Same goes for equipment: we spec what fits your throughput and budget, then commission it right.
