What's That Noise? A Metrowest Homeowner's Guide to October House Sounds

As fall settles over Framingham, Natick, Hopkinton, and Sudbury, the heat comes on and homes 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 and floors contract as nights cool. MetroWest colonials with hardwood floors and open stairways can carry sounds through the house. New cracks, sticking doors, or soft floors are worth a professional look.

Plumbing and Septic Sounds

A bang after the washer shuts off is often water hammer. Homes on wells hear the pump cycle, and some septic systems have pumps that hum. Running water when nothing is on deserves a meter check.

Furnace, Boiler, and Heat Pump Sounds

Furnaces click and whoosh, and ductwork pops. Boilers gurgle when air is trapped. Heat pumps hiss in defrost mode. New grinding, squealing, or banging is worth a call. If you smell gas, leave and call your gas utility or 911 from outside.

Wind Rattles

Wind can whistle through gaps around windows and doors and rattle loose gutters, vents, and branches.

Squirrels, Mice, and Chipmunks

Squirrels and chipmunks are daytime visitors. Mice are active at night. Massachusetts has trapping restrictions, 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. "Scratching in the bonus room ceiling in the afternoons" points a pro toward squirrels.

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.
