What's That Noise? A Fall Home-Sound Guide for Connecticut and New York Homeowners

As October cools Connecticut and the Hudson Valley, houses start making new 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, floors, and plaster contract as nights cool and dry out once the heat runs. Older colonials and farmhouses tend to be talkative. New cracks, sticking doors, or soft floors are worth a professional look.

Well and Plumbing Sounds

Many homes in the region have private wells. The pump clicks on and the pressure tank hums. Frequent cycling can point to a leak. A bang after the washer shuts off is often water hammer.

Oil Burner, Boiler, and Furnace Sounds

Oil burners rumble at ignition. Boilers and radiators gurgle when air is trapped. Propane and gas furnaces click and whoosh. New grinding, squealing, or a loud puff at startup is worth a call. If you smell gas or propane, leave and call your utility or supplier or 911 from outside.

Wind Rattles

Wind can whistle through older windows and rattle storm windows, shutters, and gutters. Branches from mature trees often brush the roof.

Mice, Squirrels, and Bats

Mice move indoors as it cools and are active at night. Squirrels are daytime visitors. Bats roost in some attics. A licensed wildlife professional can help.

What to Tell the Professional

Describe the sound, where and when you hear it, and what else is running. "The well pump clicks on every minute overnight" tells a technician there may be a leak.

If you'd like a recommendation for a local plumber, well technician, heating professional, or wildlife service, just ask. We're happy to share names we know.
