Upgrading and repairing outdoor wiring is crucial for safety and functionality. Outdated wiring can cause fires and power outages, while newer wiring can improve the efficiency and reliability of outdoor electrical components. Castro Electric provides proper and safe upgrades and repairs to provide you with peace of mind and enhance the property’s overall safety and functionality.

Installation systems can be customized to meet the specific needs of each home, including motion sensors, cameras, and alarms. These systems can be programmed to send alerts to homeowners or law enforcement agencies in the event of an intrusion. Let us provide you with peace of mind knowing that your home is safely monitored. 

The safety and smooth functioning of electrical systems should not be compromised. Our professional electricians are trained to assess the electrical wiring requirements of a new home and install the necessary wiring to meet the building code standards.

Landscape lighting enhances outdoor spaces and safety. It can illuminate pathways, buildings, trees, and water features, and create ambiance in entertainment areas. Options include LED lights, solar lights, and wired systems. LED lights are energy-efficient and low-maintenance, while solar lights are sustainable. Colors and lighting effects vary from soft to bright. With proper design, landscape lighting creates a stunning outdoor oasis for daytime and nighttime enjoyment.

Upgrading lighting can significantly reduce energy usage, lower costs, and improve the overall quality of the lighting in a building.
