The answer to 'do I need smoke detector' is that smoke detectors are an essential safety device for every home. Smoke detectors are designed to detect smoke and alert you to the presence of a fire, giving you and your family precious time to evacuate safely. They are required by building codes in most areas and are one of the most effective ways to protect your home and loved ones from the dangers of fire.
Smoke detectors should be installed on every level of your home, including the basement, and within 15 feet of each bedroom door. They should be tested monthly and the batteries replaced at least twice a year. Smoke detectors have a lifespan of around 10 years, so it's important to replace them periodically to ensure they are functioning properly.
