Schedule Preventative Protection Services With Us


Let Mario Castillo Electric’s reliable, licensed, and expert electricians elevate your home and personal security with our professionally installed Power Surge and Fire Safety alarms. Once a year we will check all electrical components in your home. If there are items that need improvements, we will make recommendations and provide a timely quote on these repairs. Our full home inspections include tightening and inspecting the connections in the panel and testing smoke alarms, outlets, light switches, exhaust fans, ceiling fans, lighting fixtures, and other electrical devices. 

While most people are aware of the importance of basic safety measures like smoke/carbon monoxide detectors and fire extinguishers, many overlook the importance of surge protectors and other preventative protection services. Surge protectors help to protect your electronic equipment from damage caused by power surges, which can often be caused by severe weather conditions or electrical faults. Smoke/carbon monoxide detectors, on the other hand, can help to save lives by giving you an early warning in the event of a fire. Both of these services are highly cost-effective and can save you a great deal of money in the long run. For example, replacing just one piece of electronic equipment that has been damaged by a power surge can often cost hundreds of dollars. In comparison, the cost of a surge protector is relatively small. Similarly, the cost of damage caused by a house fire can be far greater than the cost of installing smoke detectors. As such, it is clear that preventative measures like these are well worth the investment.

Surge Protector Installation

Surges can occur when there is a sudden increase in the voltage of the electrical supply from weather-related events including lightning strikes. Voltage spikes are inevitable and can cause costly damage to your appliances or even your home. These surges can cause serious and in some cases life-threatening injuries. A surge protector is an important and beneficial device that, when added to a home, can also help to protect your electronic equipment from damage caused by power surges. This safeguard acts like a barrier to absorb the excess voltage. 

We are proud to offer a 100% customer satisfaction guarantee on all of our electrical services, and we offer a 1-year warranty. Protect your property and your peace of mind by contacting Mario Castillo Electric today to schedule a consultation - we'll recommend the best options for your residential electrical needs.

Smoke Detectors

Smoke and carbon monoxide detectors play a vital role in protecting homeowners from the dangers of fire. By alerting occupants to the presence of smoke, they give people the opportunity to evacuate the premises and call for help. Smoke/carbon monoxide detectors can also help to prevent fires from getting out of control by providing an early warning system. In addition, smoke and carbon monoxide detectors can be wired into home security systems, providing another layer of protection. Because of their many benefits, smoke and carbon monoxide detectors are required by law in many jurisdictions. Homeowners who do not have smoke detectors should consider installing them as soon as possible.

Smoke and carbon monoxide detectors are usually installed in areas where fires are most likely to start, such as kitchens and bedrooms. However, they can also be installed in other areas of the home, such as hallways and living rooms. In most cases, smoke/carbon monoxide detectors are powered by batteries, and it is important to check them regularly to ensure that they are working properly. Some smoke/ carbon monoxide detectors also have a backup power source, such as a 9-volt battery, in case the primary power source fails. We know you don't want to think about having a fire in your home, but it is imperative that you are prepared in case an emergency arises.
