Why it matters
3/5
Home-fire deaths happen where smoke alarms are missing — or not working.
½
A working smoke alarm roughly halves your risk of dying in a home fire.
10yrs
A smoke detector's lifespan. After that it's done — working light or not.
7yrs
The typical lifespan of a carbon monoxide detector.

How it works
One visit. Every detector handled.
-
Call or text
Tell us the size of the home. We pick a time that works — no window-of-four-hours nonsense.
-
The full pass
Every smoke and CO detector in the house, bedrooms to basement: new batteries, then cleaned of the dust that causes false alarms — or no alarm at all — tested, and inspected.
-
Replace what's due
Units past their lifespan — or yellowed with age, a sure sign they're done — get swapped for hardwired First Alert models with 10-year sealed backups, on the spot.
-
Sleep on it
You'll know exactly what was done and when each unit ages out. Then the whole point: you stop thinking about it.

The permanent fix
End the battery cycle for good.
The detectors we install — First Alert's SM105-AC and the smoke+CO SMICO105-AC combo — are hardwired with a 10-year sealed battery backup. No yearly battery swaps. No ladder in November. No 2AM chirp, for a decade.
When they age out, the unit tells you — and by then you'll have our number.
Colorado law
In Colorado, CO alarms aren't optional. They're statute.
Since 2009, the Lofgren & Johnson Memorial Carbon Monoxide Safety Act has required working carbon monoxide alarms within 15 feet of every bedroom in Colorado homes that are sold, transferred, rented — or remodeled under permit.
If you're not sure your home is covered, that's exactly the kind of thing we check on a basic service visit.

The story behind the numbers.
The news segment Jayson keeps on his homepage — what happens when detectors aren't maintained, told better than any statistic.
The owner
A retired firefighter's calling, done right.
My name is Jayson Sale. I started as a professional firefighter in 1999 and spent 25+ years in the fire service here in the Denver Metro area — firefighter and paramedic, now retired. In that time I've seen both sides of the same story: the homes where a working detector woke everyone in time — and the tragedies where a missing battery or a worn-out unit meant it never sounded at all.
“Working smoke & carbon monoxide detectors save lives. The rest is maintenance — and maintenance is what we do.”
I started Detector Inspectors LLC to put that experience to work before the emergency: keeping the detectors in your home clean, tested, and in proper working order, at a price that makes it easy to say yes.

Facts worth knowing
Straight answers, fire-service sourced.
- Can I just take the battery out when it chirps?
- That chirp is the detector asking for help. In fires where a smoke alarm was present but never sounded, more than two in five alarms had missing or disconnected batteries — and dead batteries caused another quarter of the failures. Silencing it by unplugging it is how those numbers happen.
- How many detectors should my home have?
- One in every bedroom, one outside each sleeping area, and one on every level of the home — basement included. The NFPA also recommends they be interconnected: when one sounds, they all sound.
- Why does “interconnected” matter so much?
- Smoke — not flame — is what kills most people in home fires, and most fatal fires happen at night. If a fire starts in the basement while you sleep two floors up, the alarm by your bed is the one that wakes you in time.
- How often should detectors be tested?
- The NFPA says test monthly, change batteries when you change your clocks, and replace the whole unit at the end of its life — 10 years for smoke, about 7 for carbon monoxide. Our basic visit covers all of it in one stop.
- Where should CO alarms be mounted?
- Near sleeping areas — Colorado's own statute uses 15 feet from every bedroom door as the rule for covered homes — and on every level. CO is invisible and odorless; the alarm is the only warning you get.
