in San Miguel de Allende
San Miguel's colonial homes are beautiful — their wiring often is not. We assess, modernize, and protect your home's electrical system: panel upgrades, whole-house surge protection, grounding, and rewiring, all to current safety standards.
Why It Matters in SMA
Your colonial home is beautiful. Its wiring may not be.
Behind the charm of an older San Miguel home, the electrical system is often decades out of date — and the CFE grid it connects to is anything but stable. Most of it stays invisible until something goes wrong.
Outdated wiring
Decades-old wiring, unsafe splices, and undersized cable are common in colonial homes — a real fire risk hiding inside the walls.
No proper grounding
Many older Mexican homes were built with no tierra física — grounding — at all, leaving outlets, appliances, and the people using them unprotected.
CFE voltage swings
Surges, spikes, and brownouts from the CFE grid quietly destroy refrigerators, mini-splits, TVs, and electronics — one event at a time.
An overloaded panel
The original centro de carga was never sized for air conditioning, an electric water heater, or modern appliances. Overloaded panels trip, overheat, and fail.
What We Do
A safe, modern electrical system.
From a full assessment to the upgrades that protect your home — handled by master electricians under architect supervision.
Electrical Assessment
A full inspection of your wiring, panel, grounding, and outlets — so you know exactly what is safe and what needs attention.
Panel & Load-Center Upgrades
We replace overloaded, outdated centros de carga with modern panels sized for how your home actually uses power today.
Whole-House Surge Protection
A surge protector at the panel shields every appliance and device in the home from CFE spikes and surges.
Grounding Installation
We install proper tierra física so your outlets, appliances, and family are protected the way modern code requires.
Rewiring
When old wiring is beyond safe repair, we rewire — replacing decades-old cable with safe, modern, correctly-sized circuits.
Capacity for New Loads
Adding air conditioning or solar? We upgrade your electrical capacity so your home can handle modern systems safely.

Frequently Asked
Electrical FAQ
Is the wiring in older San Miguel homes safe?
Often it is not. Colonial homes frequently have decades-old wiring, unsafe splices, and no grounding — risks that stay hidden inside the walls. A professional assessment is the only way to know for certain where your home stands.
What is tierra física, and does my home have it?
Tierra física is electrical grounding — the safety path that protects you and your appliances from faults. Many older Mexican homes were built without it entirely. We test for it and, where it is missing, we install proper grounding.
Do I need a whole-house surge protector?
If you care about your refrigerator, mini-splits, TVs, and electronics, yes. The CFE grid in San Miguel produces surges and spikes that damage equipment over time. A surge protector at the panel shields the whole home at once.
Why does CFE keep damaging my appliances?
Voltage instability — surges, spikes, and brownouts — is common on the CFE grid here. Each event stresses motors and electronics. Whole-house surge protection, and stable backup power, are how SMA homeowners stop the damage.
What is a centro de carga and when does it need upgrading?
The centro de carga is your breaker panel — where power is distributed through the home. It needs upgrading when it is overloaded, outdated, or when you add major loads like air conditioning or solar that it was never sized for.
My breakers keep tripping — what does that mean?
A breaker that trips repeatedly is doing its job — warning you of an overload or a fault. It should never be ignored or simply reset. We diagnose the real cause rather than treating the symptom.
Can my electrical system handle adding air conditioning or solar?
Sometimes yes, often it needs an upgrade first. We assess your panel and wiring capacity before any major addition, so the new system runs safely instead of overloading an older installation.
Do you rewire whole houses?
Yes. When wiring is too old or unsafe to repair piece by piece, we rewire — replacing the old cable with safe, modern, correctly-sized circuits throughout the home.
Are ungrounded outlets dangerous?
They offer no protection if an appliance faults — which puts both your equipment and the people touching it at risk. We can add proper grounding so your outlets meet modern safety standards.
Do you handle electrical work for renovations?
Yes. We handle full electrical for remodels and renovations — new circuits, lighting, outlets, and panel work — coordinated with the rest of your project under one team.
