“New build off FM 78 with a second floor that would not cool. They measured instead of upselling and fixed the airflow. Honest crew, came out from Seguin same week.”
When one alarm sounds, they should all sound. We install hardwired, interconnected smoke and CO detectors throughout Marion homes — the coverage code requires and safety demands.
Thanks for reaching out. We've got your request and we'll be in touch shortly, usually the same day. Need us right now? Call (830) 587-5790 — we're open 24/7.
Hardwired + interconnected
Battery alarms scattered around the house are better than nothing, but hardwired, interconnected detectors are the real protection — when one senses smoke or CO, every alarm in the Marion home goes off at once.
We install whole-home coverage to current code, including the CO protection gas and attached-garage homes need.
Call (830) 587-5790Not glamorous, genuinely life-saving. Here is what whole-home detection involves in Marion.
Interconnected detectors all sound together, so an alarm in the garage wakes you in the back bedroom — the difference that matters most at night. We hardwire them with battery backup throughout the Marion home.
Carbon monoxide protection matters in homes with gas appliances, a furnace, or an attached garage. We place CO detection correctly so it catches a leak — including from that cracked heat exchanger we check on heating calls.
Code specifies detectors in and outside every sleeping area and on each level. We install full coverage and document it — important for safety, insurance, and resale on a Marion home.
Plenty of Marion homes are on well water, septic, and propane heat rather than city utilities and natural gas. That changes how a system should be set up and serviced, and it is second nature to us — we work rural Guadalupe County every week.
| Service | Notes | Price |

All prices flat-rate, all-in, written and approved before work starts. No travel surcharge for Marion.

“Put in a Generac after we lost power and water during a storm. They sized it for the well pump too, which the other quote ignored. Worth it.”
