DIY vs Professional Installation

Installing smoke alarms requires a professional installer in the form of a licensed electrician. It ensures safety and compliance with the requirements of the state. However, those who are planning to install by themselves are putting their homes at risk and will cause insurance discrepancies. These damages will take a toll on your finances. Sometimes, it even puts lives in danger.

Paying a professional may come with a cost, but it pays off with peace of mind and safety. During installation, they can also teach you about safety switch and circuit breaker, which you have to be knowledgeable about in case a fire starts.

There is no room for regret, so kindly adhere to the safety rules prescribed by the local government. It is truly better to be sure than sorry.

Here is a quick pros and cons list of DIY installation versus professional installation.

DIY Installation

  • Has a lower upfront cost.
  • May be at risk of incorrect placement or non-compliance.

Take note for landlords: professional installation is required to avoid issues with legal or insurance. This must be strictly followed. You must also be mindful of the maintenance schedule and other technical check-ups necessary to ensure that the fire alarm is working well.
