September Home Maintenance Checklist: 10 Things to Do Before Fall

Schedule an HVAC Tune-Up Before Heating Season

Your heating system has sat idle all summer. Before you fire it up for the first cold night, have a licensed HVAC technician inspect and service the furnace, heat pump, or boiler. A professional tune-up typically includes cleaning burners, checking heat exchangers, testing electrical connections, measuring gas pressure, and verifying carbon monoxide output.

A well-maintained heating system runs more efficiently, lasts longer, and is far less likely to fail in the middle of a January cold snap. In South Jersey, a standard fall furnace tune-up costs between $80 and $150, and many companies offer discounts if you book before October. On the same visit, ask the technician to check your carbon monoxide detector and verify that your flue pipe is clear.

Clean Gutters and Downspouts Thoroughly

Clogged gutters are the single most common cause of winter water damage in South Jersey homes. When leaves and debris fill your gutters, rainwater has nowhere to go but over the sides. That water pools against your foundation, seeps into your basement, and freezes into ice dams along your roof edge that can lift shingles and cause interior leaks.

September is the ideal time for a thorough gutter cleaning in Burlington County. Most trees have not yet dropped all their leaves, so you can clear out summer debris and get ahead of the main leaf fall in October and November. After cleaning, run water through each downspout to confirm it flows freely, and check that downspout extensions carry water at least four to six feet away from your foundation.

If you are not comfortable working on a ladder, hire a professional. Our Trusted HomeCircle Partners page lists vetted gutter cleaning services in Burlington County.

Seal Windows and Doors: Check Weatherstripping and Caulk Gaps

Drafty windows and doors are not just uncomfortable. They cost you real money. According to the U.S. Department of Energy, air leaks around windows and doors can increase your heating costs by 10 to 20 percent. In a South Jersey winter, that adds up fast.

Walk around every exterior door and window in your home. Run your hand along the edges on a breezy day, or hold a lit incense stick near the frames and watch for smoke movement. Replace worn or cracked weatherstripping on doors, and apply fresh caulk around window frames where the old sealant has dried and pulled away. For single-pane or older windows, consider removable insulation film. It is inexpensive, easy to install, and can cut heat loss through the glass by more than 50 percent.

Do not forget about the gap at the bottom of your exterior doors. A door sweep that is worn or missing lets in cold air, pests, and moisture. Replace it while the weather is still mild.

Test Smoke and Carbon Monoxide Detectors

With heating season approaching, carbon monoxide risk rises sharply. Furnaces, boilers, gas fireplaces, and space heaters all produce carbon monoxide, and a malfunctioning system can fill your home with this invisible, odorless gas in a matter of hours.

Press the test button on every smoke detector and carbon monoxide detector in your home. Replace batteries in any unit that chirps or fails to sound. For hardwired detectors, verify that the backup batteries are still fresh. If any detector is more than 10 years old (check the manufacture date on the back), replace the entire unit.

New Jersey law requires smoke detectors on every level of your home and outside every sleeping area. Carbon monoxide detectors are required on every level with a sleeping area. If you are missing detectors anywhere in your home, September is the time to install them.

Service the Fireplace and Chimney

If you have a wood-burning fireplace, a professional chimney cleaning is one of the most important fall preparation tasks. Creosote, the black tar-like residue that builds up inside chimneys, is highly flammable and is the leading cause of chimney fires. The National Fire Protection Association recommends annual inspections and cleanings for all chimneys, fireplaces, and vents.

A certified chimney sweep will remove creosote buildup, check for cracks in the flue liner, inspect the damper, and look for obstructions like animal nests. Even if you have a gas fireplace, an annual inspection is worthwhile to ensure the burner, pilot, and venting are working safely. September is the perfect time to book because chimney sweeps are less busy now than they will be in October and November.

While the sweep is at your home, ask them to check the exterior chimney structure. Loose bricks, crumbling mortar, and damaged chimney crowns can let water in, and freeze-thaw cycles in winter will turn small cracks into major repairs.

Drain and Store Outdoor Hoses, Winterize Sprinklers

Frozen outdoor pipes are a classic September oversight that becomes a costly emergency in January. When water left in an outdoor hose or supply line freezes, it expands with tremendous force and can burst the pipe, often inside an interior wall where the leak goes undetected for hours or days.

Disconnect all garden hoses from outdoor spigots, drain them completely, and store them in your garage or shed for the winter. Shut off the water supply to exterior faucets from inside your home if your plumbing has interior shutoff valves. For homes with underground sprinkler systems, have the system professionally blown out with compressed air to remove all water from the pipes. This is not optional in South Jersey. A single freeze in an irrigation line can crack underground pipes that cost thousands to dig up and replace.

Finally, insulate any exposed pipes in unheated areas of your home: basements, crawl spaces, and exterior walls. Foam pipe insulation is inexpensive at any hardware store and takes minutes to install.

Inspect the Roof for Missing or Damaged Shingles

Your roof is your home's first defense against winter weather. A single missing or damaged shingle can let water into your attic, where it can rot decking, damage insulation, and lead to ceiling stains in your living room. Summer thunderstorms may have loosened shingles or damaged flashing that you have not noticed.

Walk around your home with a pair of binoculars and examine your roof from ground level. Look for curling, cracked, or missing shingles, especially around roof valleys, chimneys, skylights, and vents. Check for shingle granules in your gutters and downspouts, which indicate that shingles are nearing the end of their lifespan. Inside your attic, look for water stains, daylight coming through the roof deck, or damp insulation.

If you spot any issues, call a licensed roofer for a detailed inspection while the weather is still dry. Roof repairs are far more expensive and harder to schedule in December than they are in September. For more detailed guidance, read our Roof Repairs: Warning Signs and What to Do guide.

Inspect the Foundation and Seal Any Cracks

South Jersey winters bring repeated freeze-thaw cycles. Water seeps into small foundation cracks, freezes, expands, and makes the crack larger. Over several winters, this can turn a hairline crack into a structural concern that allows water into your basement and compromises your home's foundation.

Walk the entire perimeter of your foundation in September. Look for cracks of any size, especially around corners, window wells, and where the foundation meets the driveway or walkway. Seal hairline cracks with hydraulic cement or an epoxy injection kit from your local hardware store. For cracks wider than a quarter-inch, or cracks that appear to be growing, have a structural engineer or foundation specialist evaluate them.

While you are walking the perimeter, check that the ground slopes away from your foundation on all sides. Grading that directs water toward your home is a recipe for basement flooding. Add soil or extend downspouts to correct any low spots where water pools near the foundation.

Clean the Dryer Vent for Fire Prevention

Lint buildup in dryer vents is a leading cause of house fires in the United States. The U.S. Fire Administration reports that failure to clean dryer vents is the number one cause of dryer fires, accounting for roughly 2,900 home fires every year. As you prepare for fall and winter, when families spend more time indoors and use dryers more heavily, September is an excellent time to clean the entire vent system.

Disconnect the dryer from the wall and vacuum out the vent opening. Use a dryer vent cleaning brush kit (available at most hardware stores for $15 to $25) to reach into the duct and pull out accumulated lint. If your vent runs through a wall or up to the roof, consider hiring a professional duct cleaning service for a thorough job.

Signs that your dryer vent needs cleaning include clothes taking longer than usual to dry, the dryer feeling hotter than normal, a burning smell while the dryer runs, and visible lint around the outdoor vent cover. A clean dryer vent also improves energy efficiency, saving you money on every load.

Reverse Ceiling Fans for Winter Heat Distribution

This is the simplest task on the list, but it can make a real difference in your comfort and heating costs. Most ceiling fans have a switch that reverses the direction of the blades. In the summer, fans should run counterclockwise to create a cooling downdraft. In the winter, flip the switch so the blades run clockwise at a low speed.

When a ceiling fan runs clockwise on low speed, it gently pulls cool air up from the floor and pushes warm air, which naturally rises to the ceiling, back down along the walls. This redistributes warm air throughout the room without creating a draft. Studies show that reversing your ceiling fans in winter can reduce heating costs by up to 10 percent, and it makes rooms feel warmer without turning up the thermostat.

While you are on the ladder, dust the fan blades and check that the pull chain and light fixtures are working properly. Do this for every ceiling fan in your home, including bedrooms, living areas, and the basement.
