Frequently Asked Questions

Mario Castillo Electric is a trusted name in the electric and solar energy industries, and we pride ourselves on providing exceptional service to our clients. We understand that navigating the world of electric and solar services can be confusing, which is why we’ve compiled a list of common questions. View our resource below for homeowners and businesses.

What Payment Methods Does Mario Castillo Electric Accept?

We accept a variety of payment options including e-checks/ACH payment, Venmo, Zelle, credit cards and checks.

Are There Any Financing Options?

Yes. We offer a great financing option through Wisetack that will allow you to pay month-to-month. Many of our customers have already been approved and used this service successfully.

Do I Need a Rewire?

If your home is 50 years old or older, you probably need to rewire your home. You might be noticing flickering or dimming lights that need to be changed regularly, breakers that trip frequently, and broken or cracked sockets. Also, if your outlets are not grounded, you don't have enough sockets and the fuse electrical panel is old, rewiring your home, is the solution.

Why Should I Get an Electrical Inspection In My Home?

There are many reasons. When many of these old houses were built, there was no such thing as a building code. Over the years, you may have worked hard to get your home up to code, but you never know what you may have missed. An electric inspection can help you determine if your home's electrical system is up to code and provide code corrections where needed.
