Home safety maintenance checklist: the tasks that prevent fires, carbon monoxide and radon exposure, and how often to do each
A home safety maintenance checklist is short, and it is different from the rest of your upkeep. Most maintenance trades a small job now against a bigger repair later. These tasks guard against fire, carbon monoxide, electric shock and radon instead. The core list is: test smoke and carbon monoxide alarms monthly and replace them on schedule, clean the dryer vent yearly, have fuel-burning appliances and chimneys serviced yearly, check the fire extinguisher, test for radon where it applies, and have the wiring inspected periodically. The intervals below come from fire and health agencies in the US, UK, Australia and Canada.
Which home maintenance tasks are safety tasks?
The safety tasks are the ones that keep a fire, a carbon monoxide leak, an electrical fault or radon from going unnoticed: smoke and CO alarm upkeep, dryer vent cleaning, annual servicing of gas appliances and chimneys, fire extinguisher checks, radon testing and periodic electrical inspection. Maintainly’s task library sets a default interval for each.
The table lists each task with the default interval and accepted range from Maintainly’s task library. These are the app’s planning defaults, set to match the agency guidance quoted in the sections below. Where a manufacturer’s instructions or a local law says something different, follow that instead.
Radon testing appears in the library for the US, Canada, the UK and other countries with radon programmes, but not for Australia. The electrical inspection task (EICR) is offered for UK homes only. If you are setting up a new home, the first 90 days checklist for new homeowners shows where these tasks fit among everything else.
| Task | Default interval | Library range | Who does it |
|---|---|---|---|
| Replace smoke alarm batteries | Every 1 year | Every 12 months, test monthly | You |
| Replace smoke alarm unit | Every 10 years | Replace at 10 years | You, or an electrician for hardwired alarms |
| Replace CO alarm batteries | Every 1 year | Every 12 months, test monthly | You |
| Replace CO alarm unit | Every 5 years | Every 5 years, or the date on the unit | You |
| Clean dryer vent and exhaust duct | Every 1 year | Every 12 months | You or a vent cleaning service |
| Deep clean dryer lint trap and housing | Every 3 months | Every 3 months | You |
| Boiler annual service and gas safety check | Every 1 year | Every 12 months | Registered or licensed gas engineer |
| Furnace annual service | Every 1 year | Every 12 months | Qualified heating technician |
| Chimney sweep and inspection | Every 1 year | Annually, more with heavy use | Professional sweep |
| Check fire extinguisher | Every 1 month | Inspect monthly, service yearly | You |
| Test home radon levels (not offered in Australia) | Every 2 years | Every 2 years | You, with a test kit, or a certified tester |
| Electrical safety check, EICR (UK only) | Every 5 years | Every 5 years | Qualified electrician |
How often should smoke alarms be tested and replaced?
Test every smoke alarm monthly, replace 9-volt and backup batteries at least once a year, and replace the whole alarm 10 years from the manufacture date. That is the US Fire Administration’s guidance. Alarms with a sealed 10-year battery have no battery to change: the whole unit is replaced on the manufacturer’s schedule.
The NFPA report on smoke alarms in US home fires covers reported home fires from 2018 to 2022. It found that nearly three out of five home fire deaths (59 percent) were in properties with no smoke alarms (43 percent) or alarms that failed to operate (16 percent). The death rate per 1,000 home fires was about 60 percent lower where working alarms were present.
The same report says that when alarms failed, the usual reason was a disconnected or non-working power source, and battery problems were the most common of those. That is why the yearly battery change is on this list. See how often to replace smoke alarm batteries for the task itself.
The US Fire Administration’s smoke alarm guidance also covers placement: on every level of the home, and inside and outside each bedroom and sleeping area. The manufacture date is printed on the alarm, so check it when you change the battery.
How often should carbon monoxide alarms be replaced?
Follow the date in the manufacturer’s instructions. The CDC’s fallback is every 5 years, and Gas Safe Register says most CO alarms last between 5 and 10 years. Maintainly’s task library defaults to 5 years, so change the interval to match the date on your own unit.
The CDC’s carbon monoxide overview says more than 400 Americans die each year from unintentional CO poisoning not linked to fires. More than 100,000 visit an emergency department and more than 14,000 are hospitalised. The most common symptoms it lists are headache, dizziness, weakness, upset stomach, vomiting, chest pain and confusion.
The CDC advises checking CO detector batteries when the clocks change in spring and autumn. In the UK, Gas Safe Register’s page on carbon monoxide alarms advises an audible alarm in every room with a gas appliance, fitted to the manufacturer’s instructions.
An alarm is a backup, not the fix. Energy Safe Victoria makes the point directly: a CO alarm is a useful precaution but no substitute for correct installation and maintenance of the appliance. The guide on how often to replace a CO detector unit covers the replacement task.
How often should a dryer vent be cleaned?
Clean the dryer vent ductwork every year and the lint filter every time you use the dryer. That is the US Fire Administration’s advice, and Maintainly’s task library uses the same yearly interval for the vent, plus a deep clean of the lint trap housing every 3 months.
The US Fire Administration’s appliance fire safety page reports that failure to clean was the leading factor contributing to the ignition of clothes dryer fires in homes from 2018 to 2020, at 31 percent. The yearly ductwork interval comes from its basement and garage fire safety advice.
The yearly vent task applies to vented dryers. Condenser and heat pump dryers have no external duct, so their upkeep is the filters and housing described in the maker’s manual. The steps for a vented machine are in the guide on how often to clean a dryer vent.
How often do gas appliances and chimneys need servicing?
Once a year is the standard advice in the US and UK. The CDC says to have heating systems, water heaters and other gas, oil or coal burning appliances serviced by a qualified technician every year. Gas Safe Register says the same for UK gas appliances, and the US Fire Administration says it for chimneys.
Gas boilers, furnaces and heaters
Gas Safe Register’s advice on checking gas appliances is to have every gas appliance checked once a year by a Gas Safe registered engineer. It explains that an appliance that is badly fitted or maintained, or has a blocked flue or vent, can produce carbon monoxide. A full service can add combustion gas analysis and a check of seals and heat exchangers.
Gas Safe Register lists warning signs that mean you should call an engineer straight away rather than wait for the annual visit:
- The appliance is not working properly.
- The flame is floppy and yellow instead of crisp and blue.
- There are black or brown marks on or around the appliance.
- The boiler pilot light keeps going out.
- There is more condensation than usual inside the windows.
Chimneys and flues
The US Fire Administration’s heating fire safety page says to have heating equipment and chimneys cleaned and inspected each year by a professional. It reports an estimated 32,200 home heating fires in the US in 2021, causing an estimated 190 deaths, 625 injuries and $442 million in property loss.
Gas work and flue work are jobs for a registered or licensed professional, and the licensing rules differ by country and state. The guides on the annual boiler service and the chimney sweep and inspection cover what each visit includes.
How often should you test for radon?
Test at least once, with a long-term kit, because testing is the only way to know a home’s level. Health Canada asks for a test of at least 3 months. Maintainly’s task library then repeats the task every 2 years, which is the app’s planning default and not an agency rule.
The EPA’s page on the health risk of radon describes radon as the number one cause of lung cancer among non-smokers and attributes about 21,000 US lung cancer deaths a year to it. The level at which it says to act is 4 pCi/L.
Other countries measure in becquerels per cubic metre. Health Canada’s guideline for homes is 200 Bq/m³, and it says measurements should be made on the lowest lived-in level of the home. The UK Health Security Agency sets an Action Level of 200 Bq/m³ and a Target Level of 100 Bq/m³.
Australia is the exception among the four countries. ARPANSA’s national survey found the average level in Australian homes is about one quarter of the worldwide average, which is why Maintainly does not add this task for Australian homes. The guide on how often to test for radon explains the test itself.
Do you need a periodic electrical inspection?
In England, landlords must have the electrics in rented homes checked at least every 5 years by a properly qualified person. Owner-occupiers have no such duty, but the charity Electrical Safety First recommends an inspection at least every 10 years. Elsewhere, ask a licensed electrician what applies to your home.
The UK inspection produces an Electrical Installation Condition Report, or EICR. The UK government’s guide for landlords on electrical safety standards sets out the 5-year rule under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020. The guide notes that 2025 amending regulations extend the rules to the social rented sector.
Electrical Safety First’s guidance for owner-occupiers gives the 10-year recommendation. Maintainly’s task library offers the EICR electrical safety check for UK homes on a 5-year default, which you can lengthen if you own and live in the home.
The US figures show why wiring belongs on a safety list. The US Fire Administration estimates 24,200 residential building electrical fires in 2021, causing an estimated 295 deaths, 900 injuries and more than $1.2 billion in property loss. Electrical inspection and repair is work for a licensed electrician in every one of the four countries.
How do you check a fire extinguisher?
Look at it regularly: Maintainly’s task library sets the check to monthly. The US Fire Administration says to make sure nothing blocks your reach, that the pressure gauge is not reading too high or too low, and that the can, hoses and nozzles are not damaged, dented or rusted.
The US Fire Administration’s fire extinguisher page adds that some extinguishers need to be shaken monthly and others need pressure testing every few years. The label and the manufacturer’s instructions say which applies to yours, and when the unit should be serviced or replaced.
The same page says young children and older adults should not use fire extinguishers.
How this differs by country
United States
The US Fire Administration advises smoke alarms on every level and inside and outside each sleeping area, tested monthly and replaced at 10 years. The CDC advises yearly servicing of fuel-burning appliances by a qualified technician. The EPA says to fix a home when radon reaches 4 pCi/L. Alarm laws are set by states and localities, so ask your local fire department what applies.
United Kingdom
In England, private landlords must fit a smoke alarm on each storey and a carbon monoxide alarm in any room with a fixed combustion appliance other than a gas cooker; the government guidance says this does not apply to owner-occupiers. The Scottish Government requires interlinked alarms in every home in Scotland. The Health and Safety Executive says landlords must arrange a gas safety check every year by a Gas Safe registered engineer and give tenants the record within 28 days. The UK Health Security Agency’s radon Action Level is 200 Bq/m³.
Australia
Smoke alarm law is set by each state. The Queensland Government requires all existing private homes, townhouses and units to have interconnected photoelectric smoke alarms by 1 January 2027. Energy Safe Victoria recommends all gas heaters are serviced at least every two years by a qualified gasfitter, with a CO alarm as a backup only. ARPANSA reports low average radon in Australian homes and a household reference level of 200 Bq/m³.
Canada
Alarm rules are provincial. In Ontario, since 1 January 2026 a home with a fuel-burning appliance, a fireplace or an attached garage needs a carbon monoxide alarm on every storey, including storeys without bedrooms; the province says to test CO alarms monthly and replace batteries yearly. Health Canada’s radon guideline for homes is 200 Bq/m³, measured with a long-term test of at least 3 months on the lowest lived-in level.
Set these up as reminders
Each task below comes from Maintainly’s task library, with its default interval and the accepted range. One tap adds it to the app, where it repeats on schedule for your home.
How we put this together
Every statistic and legal requirement in this article comes from a page published by the body named in the sentence: the NFPA, the US Fire Administration, the CDC, the EPA, Gas Safe Register, the Health and Safety Executive, the UK and Scottish governments, the UK Health Security Agency, Electrical Safety First, the Queensland Government, Energy Safe Victoria, ARPANSA, the Government of Ontario and Health Canada. Each page was opened and checked on 10 October 2026 and is listed under sources.
The intervals in the table are the defaults in Maintainly’s own task library. In that library every task in the table except the furnace service carries a safety flag, which by default moves the reminder to 7 days before the due date instead of 3. We did not test any product or survey any homeowners.
This is general information, not legal, gas or electrical advice. Laws change and differ by state, province and nation, so confirm the current rule with your local fire service, regulator or a qualified professional.
Frequently asked questions
Which home maintenance tasks matter most for safety?
Start with smoke and carbon monoxide alarms, because they warn you when something else has failed. The NFPA found that 59 percent of US home fire deaths from 2018 to 2022 were in homes with no smoke alarm or one that did not operate. After the alarms, book the yearly service for fuel-burning appliances and chimneys, clean the dryer vent, and test for radon where your country advises it.
How often should smoke and CO alarms be replaced?
The US Fire Administration says to replace smoke alarms 10 years from the manufacture date. For carbon monoxide alarms, the CDC says to follow the manufacturer’s instructions or replace every 5 years, and Gas Safe Register says most last between 5 and 10 years. Check the date printed on each unit, since models differ, and test both kinds of alarm every month.
Which safety tasks need a professional?
Gas appliance servicing, chimney sweeping and electrical inspection are professional jobs. Gas Safe Register says a UK gas safety check should only be done by a Gas Safe registered engineer, and Energy Safe Victoria asks for a qualified gasfitter. Alarm batteries, extinguisher checks, dryer lint cleaning and a radon test kit are tasks most homeowners can do themselves. Ask a licensed professional if you are unsure.
Do I need to test for radon in Australia?
ARPANSA says the average radon level in Australian homes is low, about one quarter of the worldwide average, and that there is little cause for concern for the population as a whole. It also says about one in a thousand homes may have high levels and that testing is the only way to be certain. Its reference level for households is 200 Bq/m³.
Are these safety checks a legal requirement?
Some are, depending on where you live and whether the home is rented. English landlords must arrange a yearly gas safety check and a 5-yearly electrical inspection, Scotland requires interlinked alarms in every home, Ontario requires CO alarms in homes with fuel-burning appliances, and Queensland’s smoke alarm rules reach all existing homes on 1 January 2027. Check with your local authority, because this is not legal advice.
Next steps
The safety list is short: alarms tested monthly and replaced on their dates, the dryer vent cleaned yearly, fuel-burning appliances and chimneys serviced yearly, the extinguisher checked, radon tested where it applies and the wiring inspected on schedule. Each interval has an agency behind it, and each is easy to forget because nothing looks wrong until it fails.
Add these tasks as reminders in Maintainly with the dates from your own alarms and service records, and the app will tell you before each one is due.
