What we do
Four things, done properly.
We would rather be genuinely good at a short list than passable at everything. If a job is outside what we do well, we will tell you and point you somewhere better.
Solar & Battery
Design, installation, service and repair for rooftop and ground-mount PV, plus battery backup. A twenty-year decision, so you get straight answers before you sign.
Solar & batteryEV Chargers
Tesla Wall Connectors and every other brand of home charger, wired to a panel that can actually carry the load. We evaluate and recommend the best charger for your specific needs.
EV chargersResidential
Remodels, new construction, panel upgrades, lighting and the repairs that keep a house safe. No project is too small or too big for us.
Residential workCommercial
Tenant finish-out, service and repair, lighting and equipment circuits for San Antonio businesses. Prompt scheduling and transparent pricing, because downtime costs you money.
Commercial workSolar & battery
Solar is a twenty-year decision. Treat it like one.
Most of what goes wrong with a solar system is electrical, not solar. Undersized conductors, a service that cannot carry the interconnection, a rapid-shutdown device installed wrong — these are the problems that show up years later, and they are the reason a master electrician should be the one doing the work.
- New installations, rooftop and ground mount
- Battery backup so the lights stay on when the grid does not
- Service and repair on systems somebody else installed
- Straight answers before you sign anything
How it goes
No surprises, start to finish.
We believe in honest pricing, and we will keep you informed before any work is performed.
-
You call or write
Tell us what you need. If it is urgent we will say so, and if it is not, we will say that too.
-
We look at the actual job
Panel, service size, routing, roof. Quoting solar or a charger without seeing the electrical is guesswork.
-
You get it in writing
Scope and price up front. If something changes mid-job, you hear it from us before we do the work.
-
Installed, inspected, explained
We pull the permits, meet the inspector, and walk you through what we installed and how to use it.
From a customer
John was great, he installed my Tesla charger and when my wife bought a Tesla he came back and added a second charger. Highly recommend for all your electrical needs.
