There is no natural gas inside the gate, but propane, wood fireplaces and portable generators during outages still bring carbon monoxide risk, so we pair new smoke alarms with CO alarms. - Expert electrician - 20+ years of experience in the industry - Emergency calls 24/7 ![Electric Sandro hanging a crystal chandelier in a dining room](/images/electric-sandro-crystal-chandelier-installation-800.webp) ## Smoke & CO Detectors in Aquia Harbour: the facts Replace smoke alarms [NFPA: replace smoke alarms 10 years after the date on the back](https://nfpa.org/education-and-research/home-fire-safety/smoke-alarms) Home age [Median year built 1984; fewer than 1 in 10 homes built in 2000 or later (Census ACS 2020-2024)](https://censusreporter.org/data/table/?table=B25034&geo_ids=16000US5102112) Gas service [No natural gas in Aquia Harbour; homes that need gas use propane](https://www.aquiaharbour.org/faq/) Generators and CO [CPSC: run portable generators outside, at least 20 feet from the home, and keep CO alarms on every level](https://www.cpsc.gov/Newsroom/News-Releases/2026/As-Winter-Storms-Threaten-Millions-in-the-US-CPSC-Issues-Safety-Tips-to-Help-Families-Prevent-Carbon-Monoxide-Poisoning-and-Fires) Permit for a hardwired alarm swap [Not confirmed: call Stafford County Building Division at 540-658-8650; new alarm wiring is new wiring and needs a permit](https://staffordcountyva.gov/services/view/frequently_asked_questions/public_works.php) Drive from our base About 21 minutes (11.8 miles) from our base in Quantico, without traffic ## How old are the smoke alarms in Aquia Harbour homes? Look at the build dates. The Census puts the [median Aquia Harbour home at 1984](https://censusreporter.org/data/table/?table=B25034&geo_ids=16000US5102112), and only about 190 of 2,512 homes were built in 2000 or later. Most went up in the 1970s and 1980s, so an alarm installed when one of these houses was new is now about 35 to 55 years old. The [NFPA](https://nfpa.org/education-and-research/home-fire-safety/smoke-alarms) says to replace every smoke alarm 10 years after the date printed on its back. If alarms were swapped one at a time over the years, the brands may be mixed, and mixed brands may not link to each other. We check the date on each one, replace any that are past due, and test that they sound together. Aquia Harbour has its own Stafford Fire and Rescue station on Washington Drive. The county says [Station 9](https://stories.opengov.com/staffordcountyva/published/djJRAotAi) covers Aquia Harbour and the Garrisonville and I-95 area. A working alarm is what gives you time to get out while they are on the way. ## Do you need CO alarms in a house with no natural gas? Yes, often. The [association FAQ](https://www.aquiaharbour.org/faq/) says natural gas is not available here, and homes that need gas use propane. The Census counts about [97% of homes heating with electricity](https://censusreporter.org/data/table/?table=B25040&geo_ids=16000US5102112,05000US51179). But a propane range, water heater, fireplace or grill still burns fuel. So does a wood fireplace, or a car warming up in an attached garage. Outages are the bigger worry here. An all-electric house gets cold fast when Dominion's lines go down, and that is when people reach for a portable generator. The [CPSC](https://www.cpsc.gov/Newsroom/News-Releases/2026/As-Winter-Storms-Threaten-Millions-in-the-US-CPSC-Issues-Safety-Tips-to-Help-Families-Prevent-Carbon-Monoxide-Poisoning-and-Fires) says to run a generator outside only, at least 20 feet from the house, and that a porch or carport is too close. It also says to keep CO alarms on each level and outside sleeping areas. Propane tanks here have their own rules. The association's [building guide](https://www.aquiaharbour.org/editor_upload/File/Governing%20Docs/Construction%20Maintenance%20Procedures.pdf) says a new tank must follow Stafford ordinances and needs a county permit before the ACC will approve it. ## Hardwired alarms and permits in Stafford Swapping a hardwired alarm for a new one on the same wiring is a gray area. Stafford's [FAQ](https://staffordcountyva.gov/services/view/frequently_asked_questions/public_works.php) does not name smoke alarms, and the state code does not list them as exempt. Ask the Building Division at 540-658-8650 before the job. Adding alarms where there were none, or running a new wire to link them, is new wiring. The same FAQ says new wiring needs a permit. Combination smoke and CO alarms can often go on the same wiring, which keeps the job simple. Alarms are inside the house, so the ACC has nothing to approve. ## What it costs ### Typical Northern Virginia market range (not a quote) Job Market range Hardwired smoke or combo smoke/CO detector, replace existing (unit included) $100 to $200 per detector Market data for Northern Virginia, not a quote from Electric Sandro.

Every 10 years from the date on the back, per the NFPA. Most homes here were built in the 1970s and 1980s, so check every alarm's date. We replace the old ones and test them together. Do I need a CO detector in Aquia Harbour if there is no natural gas? Usually yes. Propane appliances, fireplaces, attached garages and portable generators can all make carbon monoxide. The CPSC says to keep CO alarms on every level and outside sleeping areas. Is it safe to run a generator in my garage during an Aquia Harbour outage? No. The CPSC says to run portable generators outside only, at least 20 feet from the house, never in a garage, porch or carport. A CO alarm inside is your backup warning. Do I need a permit to replace hardwired smoke alarms in Stafford County? Stafford has not posted a rule for a same-wiring swap, so call the Building Division to confirm. Adding new alarms or new wiring needs a permit.
