Permits

Permits and inspections

Not every job requires a permit. When the local AHJ requires one, we pull it, schedule the inspection, and stay with the job until it passes. No paperwork on you.

Warranty

What's covered

Written warranty: 5-year on outlets, fixtures, and EV chargers; 10-year on wire and breakers; lifetime on panelboxes and surge protection. Parts and labor. Transfers with the home.

05 - WHO TO HIRE

Why hiring a licensed electrician matters.

For smoke and co detector wiring, here's the honest comparison. We'd tell you the same thing if we weren't trying to win the job.

Keil Electric

A licensed electrician

Licensed electrician walks every job. Veteran-owned, family-run.

Permits pulled and inspections coordinated when required by the AHJ

5/10-year + lifetime warranty in writing. Parts and labor. Transfers with the home.

Fully insured + workers' comp on every crew

The price you sign is the price you pay

A handyman

Unlicensed for electrical

No state electrical license. Can do simple swaps but not panel work, rewires, or service upgrades.

No permits. Work won't pass inspection if the city audits it later.

No structured warranty. "Call me if something breaks" isn't enforceable.

If something they did causes a fire, your homeowner's insurance can deny the claim.

Cash discount may show up on the invoice.

DIY

Doing it yourself

Cheap, but only if everything goes right. Most electrical work involves load calc, code, and permitting.

A failed inspection means redoing the work. Selling the home later, the buyer's inspector flags it.

No warranty if something fails. Replacement is on you.

Live wiring is a real safety hazard. Most fatal home electrical accidents are DIY.

If you know what you're doing, fine. If you don't, call us first.

What we see for smoke and co detector wiring in San Marcos

San Marcos is a Hays County city with a Texas State University campus, downtown housing (historic to mid-century), substantial student-rental properties, and newer subdivisions on the edges. smoke and co detector wiring jobs span historic rewires, mid-century panel upgrades, multi-unit and rental-property work, and newer-construction additions.

How smoke and co detector wiring typically runs in San Marcos

Smoke and CO detector installs map to current code, bedrooms, hallways outside bedrooms, every story including basement, near the kitchen for combination smoke/CO, and CO detectors near sleeping areas in dwelling units with fuel-burning equipment or attached garages. Hardwired detectors interconnect via 3-conductor cable so when one alarm activates all alarms sound. Battery backup (10-year sealed lithium typical) keeps the detectors functional during outages. NFPA recommends replacement every 10 years; we document install dates so the cycle is tracked.

Permits and code in Texas

Austin metro cities pull permits through their own AHJs (the city of Austin uses Austin Energy and the city development services; outlying cities run through the county). The state adopts the National Electrical Code with Texas amendments. We pull the permit when the scope requires it, schedule any inspection, and close out the work in your file. San Marcos-specific permit notes go on the quote so you know what is required before any work begins.

Calls from this page reach the Austin team directly. San Marcos is part of our day-to-day coverage, dispatched from our Round Rock shop with the same crew that runs every other Austin-area job.

Common questions for Smoke and CO Detector Wiring in San Marcos

Do I need hardwired smoke detectors or are battery ones enough?

New construction and most renovations require hardwired interconnected detectors with battery backup. Existing homes built before the requirement can keep battery-only detectors but the interconnect protection is meaningful.

How many detectors do I need?

Minimum: one in each bedroom, one in each hallway outside bedrooms, one per story. CO detectors near sleeping areas if fuel-burning equipment or attached garage. We map per code on the site walk.

What is the difference between smoke and CO detectors?

Smoke detectors sense particulate matter from combustion. CO detectors sense carbon monoxide gas. Combination detectors do both. CO is required where fuel-burning appliances or attached garages exist.

How often should I replace smoke detectors?

Every 10 years per NFPA. The sensor degrades over time. We document install dates so you know when to replace.

Can existing detectors be made interconnected?

Wireless-interconnect detectors can join an existing system without rewiring. Hardwired interconnect requires a 3-conductor cable between detectors. We pick the right path per home.
