CO Detector Coverage
Every sleeping area and fuel-burning appliance covered, with UL-listed detectors fitted to Texas code.
Coverage Gaps & Fixes
The unit itself is rarely the problem. Placement, power type, and coverage gaps are where most homes fall short.
A detector mounted far from sleeping areas gives no useful warning overnight, when CO exposure risk is highest.
Texas code requires a UL-listed CO alarm within 10 feet of each sleeping area in homes with fuel-burning appliances.
An attached garage is a separate code requirement, vehicle exhaust can push CO through shared walls or door gaps into living spaces.
A detector near the interior garage door is mapped as a required position, independent of other gas appliance coverage.
A smoke alarm detects combustion particles, not CO gas, relying on one for both leaves the home without real CO coverage.
A combination smoke and CO alarm works only when positioned correctly for both functions, which the installer confirms at each location.
26 TAC 748.3193 prohibits detectors covered by furniture or drapes, a blocked unit may not register dangerous CO levels in time.
Each detector is mounted per manufacturer spec with unobstructed airflow, then sensor-tested before the job is signed off.
What We Cover
From single-level homes with one gas appliance to multi-story houses with attached garages, coverage is mapped to the actual layout.
UL-listed detector fitted within 10 feet of each bedroom, meeting the Texas code requirement for homes with fuel-burning appliances.
A detector on every floor of a multi-story home ensures CO from a lower-level appliance is caught before it reaches upper sleeping areas.
A detector near the interior garage door addresses vehicle exhaust risk, a separate code trigger from gas appliance requirements.
Draws power from the home’s electrical circuit with battery backup, the preferred choice where wiring is accessible and outage protection matters.
A UL-listed battery unit used where hard-wiring is not practical, fitted and sensor-tested to the same placement standard.
A single UL-listed unit covering both smoke and CO detection, positioned to satisfy the correct mounting requirements for each function.
Sensor function confirmed before the job closes.
Every fuel-burning source mapped before hardware is mounted.
Hard-wired or battery unit chosen to match your home’s wiring.
Why Choose Us
Correct coverage means nothing if the job is not accountable, here is how we back the work we arrange.
You receive an itemized estimate listing every detector, bracket, and labor cost before any work is scheduled.
Our partners work to 26 TAC 748.3193 and IRC requirements, so UL-listed units go in the right positions the first time.
Every fuel-burning appliance and sleeping area is identified before hardware is touched, so no position is missed.
Each detector’s test button is checked before the installer leaves, confirming the unit is live and reporting correctly.
After the job, we verify every detector is reporting as it should, not just assumed to be working after mounting.
How It Works
01
Share your home’s layout and appliance details so we can arrange a local installer to visit and provide a written, itemized estimate.
02
The installer surveys every fuel-burning source and sleeping area, then mounts UL-listed detectors at each code-required position.
03
Every unit is sensor-tested before the installer leaves, and we follow up to confirm each detector is reporting correctly.
