Hardwired Smoke & CO Detector Installation
Selling the house and the inspector said the smoke detectors need upgrading? Standard. We hardwire interconnected units through the whole house — typically a one-day job.

Questions we get every week
Smoke & CO Detectors, asked and answered.
If your question is not here, call us. Most questions we answer by phone take five minutes.
(516) 529-6991A: For new construction, renovations, and most sale C/O inspections in Nassau/Suffolk — yes. Battery-only is not enough.
A: Depends on scope. A whole-house interconnect typically gets permitted. A one-for-one swap of existing hardwired heads doesn't.
A: Typical 3-bedroom LI Cape: 5-7 units (one per bedroom, one per hall, one basement, one kitchen CO combo). We'll tell you on the walk-through.
