If you own a home anywhere around Boston, the work you do in October decides what your March looks like. Between older housing stock, nor’easters, and constant freeze-and-thaw cycles, New England winters find every weak spot in a house.

The good news is that most of the expensive surprises are preventable with a few free or low-cost projects. Here are five to finish before the first hard freeze.

1. Clear your gutters and fix your drainage

Water is the most common cause of winter damage, and it usually starts with gutters.

  • Clear leaves and debris from gutters and downspouts.

  • Point downspouts at least five feet from your foundation.

  • Check that the ground near your foundation slopes away from the house.

Clogged gutters cause ice dams in winter, which force water under your shingles. In spring, poor drainage plus snowmelt and rain is how basements get wet. This is a free Saturday project that can prevent a four-figure repair.

2. Get your furnace or boiler serviced now

Many homes across Greater Boston are still heating with older systems. The first real cold snap is the worst time to find out yours has a problem, because every technician in the area is booked solid.

Schedule your service in October. You’ll get an appointment, usually pay less, and have a chance to catch a small issue before it becomes a no-heat emergency.

3. Find and seal your drafts

Air leaks quietly drive up your heating bill. Check these spots:

  • Windows and exterior doors

  • The attic hatch

  • Rim joists in the basement

  • Gaps around pipes and vents

Caulk and weatherstripping are inexpensive fixes. Also look into a Mass Save home energy assessment. It’s often available at no cost and can open the door to rebates on insulation and other upgrades. Program terms change, so confirm the current details on the Mass Save website.

4. Walk your exterior: roof, chimney, and siding

Take ten minutes and walk around your house with your eyes up. Look for:

  • Missing or lifted shingles

  • Cracked or failing caulk around windows and trim

  • Gaps where animals can get into the house

  • A chimney that hasn’t been inspected in years

Freeze-and-thaw cycles turn small gaps into big repairs. Water gets in, freezes, expands, and widens the opening. Fixing it in October costs far less than fixing it in February.

5. Shut off your outdoor water

This is the one most homeowners forget, and it’s one of the most expensive winter surprises.

  • Disconnect and drain your garden hoses.

  • If you have an interior shutoff valve for your outside faucets, close it and drain the line.

  • Frost-free spigots work differently, but they still fail if a hose is left attached.

A frozen spigot can crack a pipe inside the wall, and you may not know until it thaws. It’s a ten-minute job that prevents a major water-damage claim.
