Professional Smoke Detector Replacement
If an alarm is expired, chirping or failed, our licensed electricians replace every smoke alarm in your home in one visit, hardwired or battery, with a per-unit price you know before we arrive.
Three signs the alarm is done
The date on the back has passed
Every alarm carries a manufacture date on the back of the unit, and ten years past that date it is expired. The National Fire Protection Association (NFPA) and alarm manufacturers both recommend replacement every 10 years.
It chirps through fresh batteries
A chirp that survives a battery change is the unit announcing end of life. On hardwired models it can also mean a wiring or compatibility fault. Either way, it needs replacing, and batteries won’t change that.
One failed, the rest are next
Detectors installed together expire together. When one fails a test or starts chirping, its siblings are the same age. Replacing the whole set in one visit keeps every room protected and every model compatible.
How replacement works
- Count your detectors, get your number. Pricing is per unit and includes labor, materials and tools. You know the total before we arrive.
- One visit, every alarm. We replace smoke and CO units together, hardwired or battery, match compatible models across brands, and bring the ladder for vaulted ceilings.
- Test, dispose, date. We test the interconnect so the set talks to each other, take the old units away, and note the date your new alarms are due for replacement.
Hardwired and interconnected systems are household wiring. That work belongs to a licensed electrician, and it’s what our crew does every day. How hardwired replacement works.

Replacement questions
How do I know my smoke detectors need replacing?
Check the manufacture date printed on the back of the unit. Ten years past it, the alarm is expired. A chirp that survives a fresh battery or a failed test button are the other two signals. Any one of the three means replacement.
Do you replace both hardwired and battery alarms?
Yes. Battery units are straightforward; hardwired and interconnected systems involve household wiring and brand compatibility, which is why our crews are licensed electricians. We handle both in the same visit.
Should I replace all the detectors at once?
If they were installed together, they expire together. Replacing the whole set in one visit keeps every room protected, keeps the models compatible with each other, and costs less per unit than a string of one-off calls.
What does smoke detector replacement cost?
We price by the unit, and the per-unit price includes labor, materials and tools. Count your detectors, tell us what you have, and you get the exact number before we arrive. No trip fees appearing on the invoice.
Count your detectors. We’ll do the rest.
One visit, every alarm replaced and tested, old units gone, and the price agreed before we knock.
