Most companies treat smoke detectors as an accessory. We treat them as the only safety device in a home that the entire family's lives may depend on while they're asleep. That difference shapes how the work gets done.

Across Your City & Surrounding Areas, the typical home has detectors that are older than the youngest child living in it. KDD Electrical Service handles smoke detector installation as a real install — verified, documented, and tested at every detector head.

Who This Page Is For

If your detectors are over a decade old, if you don't know how old they are, if you've recently bought a home, if you're a landlord, or if an inspection flagged your detectors — this page is for you.

Why You Should Stop Trusting the Test Button

The test button only confirms the alarm sounds. It does not test the smoke-sensing chemistry, which degrades silently after 10 years.

Most homes in Your City have detectors well past their replacement age. Don't wait for a fire to find out.

Frequently Asked Questions

How often should smoke detectors be replaced?

Every 10 years, regardless of how they perform on the test button. The sensors degrade silently.

What's the difference between ionization and photoelectric?

We default to dual-sensor units that detect both fast flaming fires and slow smoldering fires.

Do I really need carbon monoxide detection?

Yes if you have an attached garage, gas appliances, fireplaces, or fuel-fired water heaters.

Can I install smoke detectors myself?

Battery-only units yes. Hardwired interconnected systems require a licensed electrician for code compliance and insurance.

Get Clarity Before Committing

This isn't a category where waiting pays off. If your detectors are over a decade old, or you don't know how old they are, reach out to KDD Electrical Service for a straight assessment in Your City & Surrounding Areas.
