Why check your alarms right now
Daylight saving time ended Sunday, November 1, and plenty of fire departments use the clock change as a reminder to walk through the house and test every alarm. It is also the season when furnaces, fireplaces and space heaters come back into regular use in Reston townhomes, condos and single-family homes. If you have not read it yet, our fall furnace and carbon monoxide checklist covers the heating side.
How the free smoke alarm program works
According to the Fairfax County Fire and Rescue Department website, residents can get free battery-powered smoke alarms by contacting their local fire station or by submitting the form on the county page. The page lists no income or age requirement.

- Step 2: A department member contacts you to schedule a visit.
- Step 3: They check your current alarms and install new ones at your house or apartment.
For program questions, the county lists 703-246-3801 and fire.smokealarms@fairfaxcounty.gov. The page does not state how many alarms a household can receive, so ask when you schedule.
The hard-wired alarm catch
The county is clear that fire department personnel are not able to repair or replace hard-wired smoke alarms. A certified electrician is needed for those. Many Reston homes have a mix of wired and battery units, so the visit can still be useful for the battery-powered alarms in bedrooms, basements and hallways.
What this means for Reston homeowners
Think of the visit as a free, five-minute item on your home maintenance list. Knowing which of your alarms are wired and which run on batteries also helps when you prepare to sell. A buyer’s inspector often notes missing or non-working alarms, and fixing that ahead of time is one of the least expensive prep items. If you are buying, ask your inspector to note where the alarms are and whether they work. For what a specific contract or disclosure requires, check with your real estate attorney.
