For many families who've recently relocated to Huntsville or Madison, the first fall in a new home brings unfamiliar sounds. Most have ordinary explanations.
Before tracking one down, note when it happens, where it seems to come from, and what else was going on.
Why Homes Creak and Pop
Wood framing and drywall expand on warm afternoons and contract on cool nights. New construction can be especially talkative during its first year as materials settle. New cracks, sticking doors, or soft floors are worth a professional look, and builder warranties may apply.
Plumbing Noises
A bang after the washer shuts off is often water hammer. Ticking as hot water runs comes from pipes expanding. Running water when nothing is on deserves a meter check.
Heat Pump and Furnace Sounds
Heat pumps are common here. They whoosh and hiss in defrost mode on cold mornings. Gas furnaces click and hum. New grinding, squealing, or banging is worth a call. If you smell gas, leave and call Huntsville Utilities or 911 from outside.
Wind and Storms
Fall storms can whistle through gaps around windows and doors and rattle gutters and vents.
Squirrels, Mice, and Crawlspace Visitors
Squirrels are active during the day, and flying squirrels and mice at night. Crawlspaces can shelter rodents. A licensed pest or wildlife professional can help.
What to Tell the Professional
Describe the sound, where and when you hear it, and what else is running. "A pop from the bonus room ceiling every evening around sunset" helps a builder or inspector understand what's happening.
