Smoke Detector Chirping With a New Battery, or All Alarms Going Off

New battery, still chirping — or every alarm screams at 3 a.m. with no smoke. The detectors are telling you they are done.

Why It Happens

What It Usually Is

Three causes cover almost every call we get for this.

End of life

Detectors expire at 10 years. The chirp pattern or a date on the back tells you.

A failed unit on the interconnect

One bad detector trips all of them. Finding which means testing each.

Wiring fault

A loose interconnect or power wire at one detector. Random alarms, especially at night when the house cools.

Before You Call

Worth Trying First

Takes a minute, costs nothing, fixes it more often than you would think.

Look at the manufacture date on the back of the detector. Ten years or older: replace, do not troubleshoot.

Still happening? That's our job.

How It Works

What Happens When You Book

We test each detector, replace the failed unit or the whole set with interconnected smoke and carbon monoxide detectors with sealed ten-year batteries, and put them where Washington code wants them — every bedroom, every hallway outside bedrooms, every floor.

You Book

Online or by phone. A technician reaches out within 1 business hour.

We Find It

Traced to the box or device it lives in. Exact price before any work, you approve it first.

Fixed and Tested

Right parts, tested under load, next connection checked so it does not come back.

FAQ

Common Questions

A hardwired smoke detector that keeps chirping after a fresh battery is almost always telling you it has reached end of life — detectors are built to expire at ten years — or that the hardwired unit has failed. When every alarm in the house goes off together with no smoke, one unit on the interconnect wire has failed or a wiring fault is triggering the chain. Both mean replacing the detectors; since they were all installed together, replacing the set with new sealed-battery, interconnected units is the fix that lasts another decade.

Yes, and that is the right fix for a set that was installed together. Usually one to two hours.

Washington requires CO alarms in homes with fuel-burning appliances or an attached garage. We install combination units.

Exact price before any work starts, lower per unit for the whole set.

Usually within a day or two. Alarms going off all night: call and we fit you in sooner.
