Smoke and CO Detector Installation in Dumfries, VA

How old are the alarms in your Dumfries home?

The U.S. Fire Administration says to get new smoke alarms every 10 years. It also says to put them inside and outside each bedroom and on every level, and to choose interconnected alarms so that when one sounds, they all sound.

In Dumfries, the median home was built in 1983, and about 992 homes went up in the 1970s and 1980s (Census ACS). Hardwired alarms put in when those homes were new have been due for a change for decades. Look at the back of each alarm for a date. If it is more than 10 years old, or has no date at all, replace it.

Older hardwired systems may also have fewer alarms than today's code asks for new work. If a home has one alarm in the hall and none in the bedrooms, adding alarms means new wire, and new wire needs a permit.

Gas and propane heat in Dumfries: why CO alarms matter

Carbon monoxide comes from fuel-burning appliances like furnaces, water heaters and ranges. The Census ACS shows about 730 occupied homes in Dumfries heat with utility gas and about 81 with bottled or tank gas. A gas range or gas water heater counts too, even in a home with electric heat.

Natural gas in Prince William County comes from Washington Gas, which notes that some areas of the county are served by Columbia Gas instead. Your gas bill shows which one serves your home. Either way, the gas company handles leaks and the meter. CO alarms are your job inside the home.

The CPSC advises CO alarms on each level of the home and outside sleeping areas, and says interconnected units are good to have. It does not advise putting them in the kitchen or right above a fuel-burning appliance. Combination smoke and CO alarms can cover both jobs from one box.
