Winter-Ready Homes: Siding & Window Tips to Keep Out the Cold

How Platteville Homeowners Can Boost Insulation, Seal Drafts, and Improve Weather Resistance Before Winter Hits

Winter in Platteville is unforgiving. The cold arrives fast, the winds pick up, and any weakness in your siding or windows becomes obvious the moment the furnace kicks in. Heat loss, drafts, moisture intrusion—these problems don’t just impact comfort; they drain your wallet and shorten the lifespan of your home’s exterior.



Martin Construction has spent decades helping Platteville residents fortify their homes against Wisconsin winters. Here’s what every homeowner should know to stay protected, efficient, and comfortable all season long.


Why Exterior Prep Matters Before the Freeze

Your home’s siding and windows act as a barrier between you and extreme weather. When they’re compromised—even slightly—cold air slips in, warm air escapes, and your energy bills spike. Winter exposes every flaw:

  • Gaps expand as temperatures drop
  • Moisture freezes and worsens minor cracks
  • Wind pressure forces drafts through weak seals
  • Inefficient windows bleed heat nonstop


Getting ahead of these issues is the best way to avoid mid-winter repairs.


Strengthen Insulation Through Your Siding

Siding is more than curb appeal—it’s a critical layer of insulation. If yours is outdated or worn, cold air will find its way into your walls.

Upgrade to Insulated Siding

Modern insulated vinyl and fiber cement siding add thermal resistance where older materials fall short. They help maintain interior warmth and reduce heating costs.

Check for Loose or Damaged Panels

Even one loose panel creates an entry point for wind and moisture. Winter storms only make it worse. Repairing or re-securing panels now prevents bigger problems later.

Watch for Moisture Issues

Warping, bubbling, or soft spots indicate water infiltration. If moisture gets beneath your siding and freezes, it can cause cracking, mold, and structural deterioration.


Seal Up Weak Points Before the Cold Arrives

Small gaps become big problems in winter. Targeted sealing around siding joints, trim pieces, and utility lines closes the pathways cold air uses.

Replace Worn Caulk and Sealant

Caulking deteriorates over time, especially under UV exposure. Re-caulking edges around windows, doors, and siding trim restores your home’s weather-tight seal.

Inspect Flashing Around Windows and Rooflines

If flashing is bent, missing, or improperly installed, winter storms can push water behind your siding. This leads to rot and expensive repairs.

Look for Gaps Near Pipes, Outlets, and Vents

Any penetration through your exterior needs airtight sealing. Rodents also love these access points when temperatures drop.


Windows: Your First Line of Defense Against Cold

Windows are one of the biggest sources of heat loss in older homes. Even high-quality units can leak warmth if they’re aging or poorly sealed.

Check for Drafts Around the Frame

If you feel cold air or notice condensation inside, your seals have likely failed.

Upgrade to Energy-Efficient Windows

Double- or triple-pane windows with Low-E coatings dramatically improve insulation and reduce heat transfer.

Repair or Replace Damaged Weatherstripping

Weatherstripping wears down with seasonal expansion and contraction. Replacing it restores a tight, energy-saving seal.

Inspect Window Frames for Rot or Warping

Wood rot or frame warping creates gaps you can’t fix with sealant alone. Replacement becomes the smarter long-term solution.


Boost Weather Resistance for the Harshest Days

Cold isn’t the only enemy—wind, ice, and snow buildup can strain your siding and window systems. Preparing for these conditions now ensures your exterior can take the punishment.

  • Add storm panels or interior window inserts to reduce heat loss
  • Ensure proper attic ventilation to prevent ice dams that can leak into siding
  • Clean gutters and downspouts to stop overflow from damaging siding
  • Inspect exterior trim for cracks or separations
  • Reinforce older siding systems to improve storm resilience


A winter-ready home isn’t just warmer—it’s stronger and far more efficient.
