🧪 Inspection, Testing & Maintenance
Because Problems Don’t Fix Themselves

“How do I know my electrical system’s actually safe?”
“Is my wiring up to code, or a fire hazard waiting to happen?”
“What’s really going on behind my walls?”

Most electrical problems don’t announce themselves—they sit quietly in the background, getting worse by the day. Then suddenly… they cost you thousands in damage, downtime, or worse.

At JMS Electrical, we don’t wait for things to break. We find the issues before they become problems.

That’s what our Inspection, Testing & Maintenance service is all about—keeping your system healthy, safe, and reliable, 24/7.

🧠 Why You Can’t Ignore This Stuff

Think of your electrical system like your car. If you don’t inspect it, test it, and service it—it fails when you least expect it.

Here’s what neglecting electrical maintenance can cost you:

  • Surprise outages

  • Damaged equipment

  • Fire risk

  • Failed inspections

  • Insurance problems

  • Expensive emergency repairs

You don’t want that. And you don’t need it. That’s why preventative care always wins.

 
 

 

 

🔍 What We Actually Do

We don’t just “look around.” We perform detailed inspections and certified testing that catch the stuff most people miss.

Our services include:

  • Full electrical safety inspections

  • Load testing & balancing

  • Thermal imaging to detect overheating components

  • Grounding & bonding checks

  • Circuit and breaker testing

  • Surge protection evaluation

  • Compliance inspections (for local code, NEC, OSHA, etc.)

  • Maintenance for panels, switchgear & emergency systems

  • Test reports + written documentation for your records

Whether it’s your home, office, warehouse, clinic, or commercial unit—we tailor the testing to your setup.

⚙️ One-Time Inspections or Ongoing Maintenance? We Do Both.

Sometimes you just need a one-time inspection before buying, selling, or renovating.

Other times, you want routine maintenance to catch issues before they break something.

We offer:

  • One-off inspections

  • Annual testing plans

  • Quarterly preventative maintenance

  • Custom contracts for commercial & healthcare facilities

With JMS Electrical, you’re not locked into anything. You get what you actually need. That’s it.

🏢 Real Example, Real Win

One of our commercial clients was dealing with random system shutdowns. Their old electrician said “everything looks fine.”

We did a full thermal scan. Turns out a single breaker was overheating under load—and on the verge of failure. Swapped it out same day. Problem solved. No downtime. No disaster.

That’s what proper testing catches.

🚨 Warning Signs You Shouldn’t Ignore

If you’re seeing (or hearing) any of this, it’s time to call:

  • Lights flickering without reason

  • Burning smell near panels or outlets

  • Breakers tripping regularly

  • Unexplained power loss in part of the building

  • Buzzing or crackling sounds from panels

  • Your electrical setup hasn’t been checked in over 2 years

These aren’t “minor annoyances.” They’re warning signs.

✅ What Makes JMS Electrical Different?

  • We don’t just inspect. We explain. You’ll know exactly what’s working, what’s not, and what to do next.

  • We use the right tools. Thermal scanners, load testers, and diagnostic gear—not just flashlights and guesswork.

  • We build reports that help you plan. Maintenance schedules, risk flags, upgrade suggestions—clear and to the point.

  • We’re licensed, insured, and experienced. No corner cutting. Ever.

🔌 Don’t Guess. Know.

Electrical issues don’t usually scream. They whisper—until something breaks, overheats, or sparks out. If it’s been more than a year since your last inspection… you’re already overdue.

Let’s fix that.

We’ll make sure your system isn’t just working—but working right.
