How many smoke alarms can you replace in an hour?

Up to four smoke alarms, or a CO detector, fit in the about-1-hour group on our estimator. Up to eight alarms fit in under two hours.

Why is my smoke alarm chirping?

A chirp usually means a low battery or an expired alarm. Most alarms need replacing every 10 years; the date is printed on the back.

Can you replace hardwired alarms with a different brand?

Yes. Different brands use different wiring connectors, so we swap the adapter as well to keep alarms interconnected.

How much does fixture installation cost in San Diego?

Switch Your Fixture charges a $159 service call that includes the first hour of labor. Additional labor is $159 per hour, billed in 15-minute increments of $39.75. Every service is billed at the same rate, so you can add up the time for your fixtures and multiply by the hourly rate to build your own estimate.

What happens if my fixture takes less than, or more than, an hour to install?

Our service call includes an hour of labor to install your fixture. If it takes less than an hour, we offer other services to fill the time, such as changing bulbs, swapping switch plates or hanging a picture. Additional labor is billed in 15-minute increments at our hourly rate.

What if the fixture I bought doesn’t fit?

If we arrive and your fixture doesn’t fit, we only charge a 15-minute consultation fee ($39.75). The consultation gives you the information you need to buy the correct fixture, and we rebook your install.

Can you install multiple fixtures on the same visit?

Yes, that’s what we do. Every fixture is billed at the same rate, so put your whole list in one request: a fan, a faucet, a TV and a doorbell can all go in on the same trip under one service call.

Do you warranty your work?

Yes. We warranty all of our installations. If something we installed is not working the way it should, call or text (619) 677-8677 and we will come back and make it right.
