They didn't stop there, them and my landlord fixed our generator, we couldn't get it going, left the fan for us to use, filled the gas in the generator. I hope they know just how much we appreciate all their kindness. The city came right out an approved their work, we are all set for when Duke shows up."

Smoke Detector Installers questions, answered by experts

Different beeps generally mean different things, depending on the smoke alarm model. Continuous beeps usually mean the alarm has been triggered, so treat continuous beeps like a fire until proven otherwise. Double or triple beep sequences (where it beeps two or three times with a pause in between) may be a carbon monoxide alert. Immediately open windows and doors to vent the home, and go outside for at least 10 minutes. A single beep with a long pause in between is usually a low battery warning. 

Yes, keyless locks can deter burglars, mostly because they boost security and offer advanced features. Most models allow for unique codes or temporary access, making it harder for intruders to break in. Many of these smart locks even alert you if someone tries to tamper with them. However, you need to remember that while they provide an added layer of protection, no lock is completely foolproof. Pairing these locks with good security habits—like proper lighting and surveillance cameras—creates a strong defense to help stop intruders in their tracks.

The best window alarm sensor depends on the type of window you’re concerned about since different types of sensors will work best in different scenarios. Many homes are equipped with contact sensors, which trigger an alarm when a window is opened, and each part of the sensor breaks contact with the other. But there are other options, too, like a glass break sensor or motion sensor, which both work well for windows that are in low-traffic areas.

Professionals use secure clips, weatherproof materials, and proper electrical connections to ensure safety and durability.

Costs depend on system type, labor rates, and additional features like smart integration or professional monitoring.
