In Massachusetts, October and old houses go together. As nights cool and the heat comes on, colonials, capes, and triple-deckers all start talking. Most of the sounds 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, plank floors, and plaster contract as nights cool and dry out once the heat runs. Older homes are especially talkative. New cracks, sticking doors, or soft floors are worth a professional look.
Radiators, Steam, and Plumbing
Hot water radiators gurgle when air is trapped. Steam systems hiss and clank, and loud banging often means water is collecting in the pipes. A bang after the washer shuts off is often water hammer.
Oil Burners, Furnaces, and Heat Pumps
Oil burners rumble at ignition. Gas furnaces click and whoosh. Mini-split heat pumps hiss in defrost mode. New grinding, squealing, or a loud puff at startup is worth a call. If you smell gas, leave and call your gas utility or 911 from outside.
Nor'easters and Ice Dams
Wind can whistle through older windows and rattle storm windows and gutters. In winter, dripping inside walls or near windows after snow can signal an ice dam.
Squirrels, Mice, and Bats
Squirrels are active during the day, mice at night. Bats sometimes roost in attics. Massachusetts has specific rules about trapping and wildlife removal, so a licensed professional is the right call.
What to Tell the Professional
Describe the sound, where and when you hear it, and what else is running. "The radiator under the bay window clanks every morning when the heat starts" gives a technician a clear starting point.
If you'd like a recommendation for a local plumber, heating technician, or wildlife professional, just ask. We're happy to share names we know.
