Review alarm locations
We look at the property layout and existing detector positions to plan the work.
We install smoke detectors for homes and businesses. Our insured team offers free estimates and emergency electrical service.
A working alarm gives occupants an audible warning when it detects smoke.
A replacement removes an expired or faulty detector from service.
Compatible interconnected alarms can alert occupants beyond the room where smoke is detected.
Smoke detector installation is a service that places and connects alarms to detect smoke.

Smoke detector installation starts with the property layout and the alarm's power source. A battery-powered alarm and a hardwired alarm have different installation needs. Wiring access is a key cost consideration. Adding a hardwired alarm where no connection exists can involve more work than replacing a compatible unit at an existing connection. We recommend discussing the existing wiring before buying an alarm, especially if you want alarms that sound together. Interconnected alarms communicate with each other when smoke is detected. Compatibility matters, so we'll look at the existing setup before discussing an addition or replacement.

A little preparation helps us assess your smoke detector needs.
The power source affects the connection work and the care an alarm needs.
| Alarm type | Power connection | Buyer consideration |
|---|---|---|
| Battery-powered alarm | Uses a battery | Battery care follows manufacturer instructions |
| Hardwired alarm | Connects to property wiring | Existing wiring access affects the work |

Ask Earth Electric for an estimate for your home's or business's smoke detectors. Urgent requests get priority scheduling.

A smoke detector that stays silent during a test needs attention because occupants may not receive a warning. Leave the alarm in place and tell us what happened when you tested it. We'll discuss the detector's condition and whether a replacement or an electrical check is the right next step.
A property manager may need smoke detectors added before a rental is occupied. The layout and any existing alarm connections matter when choosing the work. Gather access details and note the current detector locations, then ask us for an estimate that reflects the property and the proposed alarm setup.
Interconnected alarms need compatible parts to communicate across a property. If an existing detector has reached its replacement date, keep its model information and tell us whether the other alarms sound together. We can discuss a replacement that fits the setup and explain whether wiring access affects the work.
