Our crews

In-house technicians, not subcontractors

Our work is done by our own crews. Customers name them in their reviews: Greg, Nathan, Tommy, Freddy and Brandon in the field, and the office team who set up maintenance plans and follow up after the visit.

We service equipment from a wide range of manufacturers, so an aging operator or an outdated keypad doesn’t automatically mean a new gate.

“We have owned 5 gate Systems over the last 40 years and done business with a host of product and service providers but Trinity Gates are head and shoulders above the rest. The technicians are extremely polite and professional and their product and service knowledge is truly impressive.”

“Very knowledgeable and friendly service for a gate that suffered a rodent intrusion. Broad range of knowledge concerning all the gate mechanism (Liftmaster) and all the related add-ons - vehicle triggered auto-open, keypad, buried detection loops, photo cells, Click2. Will be using them for a regular maintenance contract.”

“We have an older gate that has very few parts available anymore. Trinity Gate had the discontinued part (in their words, they are hoarders)…”

Gate questions we get

How often should an automated gate be serviced?

Industrial and commercial gates with heavy traffic: two to three times a year. Residential gates: at least once a year, depending on traffic.

My gate won’t close. What should I check first?

Look for anything blocking the gate’s path, then check that the power is on: outages, a tripped breaker or a damaged power line are among the most common causes. If you can’t find a simple fix, call us for repair.

How long does an automated gate last?

A good-quality gate that was installed correctly can last 15 to 20 years with routine maintenance.

Can you work on a gate another company installed?

Yes. Most of our days are spent servicing gates other companies installed, across a wide range of manufacturers.

Can I upgrade my keypad or call box without replacing the operator?

In many cases, yes. Access control and the operator do different jobs, so a keypad, call box, intercom or credential system can often be upgraded while a serviceable operator stays in place.

Can an old manual gate be automated?

Sometimes. It is treated as a new installation, because it usually needs power at the gate, conduit, controls and UL 325 safety equipment. The gate and posts also need to be sound enough to carry an operator.

Gate down? Call the office.

Talk to a person Mon–Fri 8am–4pm. We work on every major brand, including gates other companies installed.
