No job too small free estimate, upfront price

The right alarms, in the right places, wired and working, for a home that is safe and to code.

Smoke and carbon monoxide detectors are the cheapest life-safety upgrade in your house, and the easiest to neglect until one is chirping at 2 a.m. Fixed-It Home Services installs and replaces smoke and CO detectors across Phoenix, battery or hardwired, placed to code and tested before we go. Whether you are replacing aging alarms, adding carbon monoxide protection, or outfitting a whole home, we make sure the coverage is right. Free estimate up front, and real protection when it counts.

Smoke detector installation and replacement

Smoke alarms have a service life, and older units miss more than they catch. We replace aging or chirping alarms and install new ones where coverage is missing, so every part of the home is watched.

Carbon monoxide detectors

Carbon monoxide is invisible and has no smell, which is exactly why detectors matter. We install CO detectors and combination smoke-and-CO units in the right spots, so a gas furnace, water heater, or attached garage cannot become a silent hazard.

Hardwired or battery

Both have their place. Hardwired detectors with battery backup are standard in newer homes and stay powered without swaps. Battery units, including 10-year sealed models, are simple and reliable. We will help you choose what fits your home and install it correctly either way.

Interconnected alarms

Modern safety codes call for interconnected alarms, so when one sounds, they all sound. That matters in a Phoenix single-story sprawl or a two-story home, where a fire in the garage should wake someone at the far end of the house. We set up interconnected systems, wired or wireless.

Placement and code

Where detectors go is as important as having them. Code calls for an alarm in each bedroom, outside every sleeping area, and on every level of the home. We know the placement rules and install to them, so your coverage actually meets code instead of leaving gaps.

Sealed-battery and smart detectors

Tired of the chirp? We install 10-year sealed-battery detectors that you never have to change, and smart detectors that alert your phone and can tell you which room triggered. If you want a whole-home upgrade to current gear, we will handle it top to bottom.

Frequently Asked

Questions, answered

How much does smoke detector installation cost in Phoenix?

It depends on how many detectors you need and whether they are hardwired or battery. Replacing a few units is quick and affordable. Outfitting a whole home or interconnecting hardwired alarms costs more. We give upfront pricing with a free estimate so you know the number before we start.

Both work well. Hardwired alarms with battery backup stay powered without swaps and are standard in newer homes. Sealed 10-year battery units are simple and reliable, with no wiring needed. We will recommend what fits your home and code requirements, and install whichever you choose correctly.

Code calls for a smoke alarm inside each bedroom, outside every sleeping area, and on every level of the home, including basements. Carbon monoxide detectors go near sleeping areas and living spaces. We know the placement rules and install to them, so your coverage meets code instead of leaving blind spots.

It comes down to the number of bedrooms and levels. As a baseline: one in each bedroom, one outside each sleeping area, and at least one per floor, plus CO detectors near sleeping areas. We will walk the home, tell you exactly how many you need, and where each one should go.

If you have any gas appliances, a gas furnace or water heater, or an attached garage, yes. Carbon monoxide is odorless and invisible, so a detector is the only way to catch it. We install CO detectors and combination smoke-and-CO units in the right locations to protect against it.

Yes, and it is one of our most common calls. Smoke alarms have a service life of about ten years and get less reliable as they age. We replace aging and chirping units, add coverage where it is missing, and test everything, so you are protected and the middle-of-the-night chirping stops.

Yes. We install smart smoke and CO detectors that send alerts to your phone and can tell you which room triggered, which is useful when you are away from home. If you want to upgrade the whole house to smart or 10-year sealed units, we can handle the full changeover.

Yes. Interconnected alarms all sound together when any one detects smoke or CO, which is a real safety advantage in a large single-story or two-story Phoenix home. We set up interconnected systems, either hardwired or wireless, so an alarm at one end of the house wakes everyone in it. Alarms chirping or past their date?
