When one alarm sounds, they should all sound. We install hardwired, interconnected smoke and CO detectors throughout San Marcos homes — the coverage code requires and safety demands.

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 San Marcos home goes off at once.
We install whole-home coverage to current code, including the CO protection gas and attached-garage homes need.

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 San Marcos 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 San Marcos home.
The San Marcos and Blanco rivers keep the humidity up, and a tight house and a leaky house both struggle with it in their own way. Whole-house dehumidifiers, duct sealing, and UV lights in the air handler keep the mugginess and the mold pressure down. The river is the reason people move here. It does not have to live in your hallway closet.
