Aguadilla, Puerto Rico · Mayagüez to Hatillo

The perito
who signs
for it.

Thunder Electrical Services is Kevin Cordero, perito electricista. He looks at the job, he does the work, and his is the name on the certification at the end of it. One person, start to finish — nobody to pass you along to.

One man, one standard

What that actually means for you

The person who quotes it is the person who wires it

No dispatcher relaying half a description. No crew you have never met turning up in a van. You describe the problem to Kevin, Kevin looks at it, and Kevin is the one holding the screwdriver.

One name goes on the certification

A perito electricista is licensed to inspect electrical work and certify it. That signature is not a formality — it is a professional putting their licence behind what they saw. When Thunder signs, the signature belongs to the man who was standing at your panel.

He works this coast, so he can come back

West and northwest Puerto Rico — Mayagüez up through Aguadilla to Hatillo. Close enough that a second look is a short drive, not a scheduling problem. Salt air and coastal wiring behave in ways an inland electrician does not see every week.

The trade

What Thunder does

Four service lines, in Kevin's own words — with what each one means in plain English.

Instalaciones y reparaciones eléctricas

Installations & repairs

New circuits, outlets, fixtures and switches — and the repairs that come after. A dead outlet. A breaker that trips every time the microwave and the A/C run together. A light that flickers when the compressor kicks in. Found on the visit, and fixed on the visit whenever it is safe to finish it that day.

Certificaciones eléctricas

Electrical certifications

An inspection and a signed certificate from a licensed perito electricista. Banks, insurers, permit offices and buyers ask for one. Kevin inspects, writes down what he found, and either signs it or tells you exactly what has to be corrected first — and he can do the correcting.

Reparación de base de contadores

Meter base repair & replacement

The meter base is the steel box on your outside wall that the utility's meter plugs into. On this coast, salt gets into them and corrodes the lugs where the conductors land. Kevin repairs them, replaces them, and re-does the service entrance around them.

Otros servicios eléctricos

Other electrical work

Service masts and risers, panel and load-centre work, rough-in for a remodel, and the jobs that do not have a tidy name. If it runs on electricity and it is worrying you, ask — he will tell you straight whether it is his work or somebody else's.

Base de contadores

What a meter base is, and why yours matters

On the outside wall of your house there is a round meter sitting in a steel socket. That socket is the base de contadores — the meter base. It is the exact point where the utility's wires stop being the utility's problem and start being yours.

Everything from that box inward belongs to the property owner: the box itself, the lugs the incoming conductors land on, the conduit, and the seal that is supposed to keep weather out of all of it. Most people have never looked at theirs.

On this coast the thing that kills them is salt. It works into the seams, lifts the paint, and corrodes the aluminium conductors where they are clamped down. A corroded connection is a loose connection, a loose connection runs hot, and heat is what melts a meter base — usually taking the meter, the service conductors and a patch of wall with it.

What you can see from the ground

  • Rust streaks running down the wall below the meter
  • A cover that no longer sits flat, or a door that will not close
  • Scorch marks or brown discolouration around the meter ring
  • The whole house dimming when a big motor starts, not just one room
  • A hot smell near that outside wall

Any one of those is a reason to have it looked at, not a reason to wait and see.

Kevin's own photo A new meter base going into a concrete wall that had to be opened up to receive it. The red boots cover the lugs where the conductors land — the exact connections that corrode when salt gets in. Still to shoot: the same wall finished and sealed, from far enough back to see the whole service entrance.

The work

Jobs off this coast

Kevin's own photographs of his own installations. No stock, no borrowed portfolio.

An open load centre with two rows of branch breakers landed and the neutral and ground conductors run to their bars.
Kevin's own photo A load centre with the cover off. Every branch breaker landed, the neutrals and the grounds run to their own bars, the whole thing ready for the dead front to go back on. This is the view a homeowner never sees and the one another electrician judges you on.
A finished load centre with the grey dead front on, the door closed and the circuit directory card filled in.
Kevin's own photo Panel work, closed up. Cover on, door shut, directory card filled in so somebody can find the right breaker at eleven at night without guessing. The wall around it is patched back. Still to shoot: a true before/after — the same panel, same angle, both states.

Kevin's own photo A service mast and riser. The galvanised pipe that carries the incoming service up above the roofline, set in fresh concrete with the weatherhead on top. This is what has to be right before anything downstream of it can be.
A new outlet box stubbed out of a kitchen wall between two cabinet banks, with the wall chase above it patched and skim-coated.
Kevin's own photo A kitchen circuit, run and patched. A new device box between the cabinets and the chase above it closed back up and skimmed — because the part of a remodel the customer actually looks at is the wall, not the wire.

Certificaciones eléctricas

The certificate, and who is allowed to sign it

A perito electricista is a licensed electrical professional — the person the system recognises to inspect an installation and put their name to whether it is sound. Not every electrician holds that licence. Kevin does.

You will be asked for a signed electrical certification more often than you expect: closing on a property, renewing or claiming on insurance, pulling a permit, connecting or reconnecting service, or a buyer's inspector wanting comfort about a panel.

The useful part of hiring one man for both jobs is that there is no standoff. If the inspection turns up something that fails, the person telling you is the person who can fix it — and the person whose licence is on the line either way.

Kevin's own photo Inside a service disconnect — main breaker landed, neutrals and grounds dressed to their bars. The manufacturer's approval label is right there on the enclosure, which is the sort of detail a certification is actually about. Still to shoot: a signed certificate photographed flat, with the customer's name, address and licence number blanked out.
