MARTINEZ DETAILSPanel upgrades
Panel upgrades

02
Older wiring downtown

★★★★★
“The technician from Haxx immediately pointed out multiple violations of the National Electrical Code and explained that the wiring was overheating and could potentially become a fire hazard. They offered to redo the installation the correct way, pulled the proper permit, and installed the EV charger safely and professionally. The city inspection passed without any issues.”
★★★★★
“Recently, my dishwasher stopped working, and they discovered it was actually an outlet issue. Not only did they diagnose it quickly, but they also fixed the outlet—saving me from calling an electrician. Reliable, professional, and skilled at handling both appliances and electrical issues.”
★★★★★
“I purchased a couple of ceiling fans and was reluctant due to how old my house was with old wiring so I wanted someone professional and trustworthy. They have been both!”

GOOD TO KNOW
Electrical Panel Upgrade in Martinez: questions, answered.
How do I know if my Martinez home needs a panel upgrade?
A load calculation compares your service capacity with current and planned loads. HAXX does this during the estimate.
Does a panel upgrade need a permit in Martinez?
Yes. HAXX applies through the City of Martinez Building Permit Center and schedules inspection.
Do I need 200 amps?
Not always. A load calculation shows whether your current service can carry the new appliances, sometimes with load management. HAXX recommends an upgrade only when the numbers require it.
How long does a panel upgrade take?
The panel swap itself is usually one day. Permits and utility scheduling for service upgrades can add several weeks, so plan early.
