The Ultimate Winter Maintenance Guide for Your Windows and Doors

Winter is a beautiful season, but it can also be harsh on your home. Cold temperatures, snow, ice, and wind can put a lot of stress on your windows and doors, leading to drafts, water damage, and higher energy bills. To keep your home comfortable, safe, and energy-efficient, it’s essential to properly maintain your windows and doors during the winter months. At Specialty Window and Door, we’ve put together the ultimate winter maintenance guide to help you protect your investment and keep your home running smoothly.

1. Inspect for Drafts and Leaks

One of the first steps in winter maintenance is checking for drafts. Cold air entering your home can make your heating system work harder, driving up energy costs.

  • Check caulking and weatherstripping: Look for gaps or cracks around window frames and door edges. Replace any worn or missing weatherstripping and re-caulk areas where needed.
  • DIY draft tests: You can use a candle, incense stick, or smoke pen to detect leaks. Hold it near the window and door edges if the smoke wavers, you’ve found a draft.

Sealing these leaks not only keeps your home warmer but also improves overall energy efficiency.

2. Clean and Lubricate Moving Parts

Winter can make it harder for windows and doors to open and close smoothly. Dirt, debris, and cold temperatures can cause hinges, locks, and tracks to stiffen.

  • Clean tracks and sills: Remove dirt, leaves, and ice buildup from window tracks and door sills. A vacuum with a brush attachment works well.
  • Lubricate hardware: Use a silicone-based lubricant on hinges, locks, rollers, and tracks to ensure smooth operation. Avoid oil-based lubricants, as they can attract dust and grime.

Regular maintenance ensures your windows and doors remain functional and prevents damage caused by forced operation.

3. Inspect Glass and Frames

Winter weather can exacerbate existing issues with your windows and doors. Cracks, chips, or warping can become more severe under freezing temperatures.

  • Check for cracks or chips: Small cracks can expand in cold weather, so repair them promptly.
  • Examine frames: Look for signs of warping, rotting, or water damage, especially in wooden frames. Addressing these issues early can prevent more costly repairs later.

Keeping your windows and doors in top condition protects your home from drafts, water intrusion, and energy loss.

4. Manage Snow and Ice

Snow and ice accumulation can damage doors and windows if left unaddressed.

  • Clear pathways and sills: Remove snow buildup around exterior doors to prevent moisture from seeping in.
  • Avoid ice damage: Be careful when shoveling or using ice melt near your doors and windows. Some chemicals can corrode metal frames or damage finishes.
  • Use storm windows: If you have them, install storm windows to add an extra layer of insulation and protection against harsh weather.

Proper snow and ice management prevents water damage, reduces drafts, and ensures safe entryways.

5. Protect Against Condensation

Condensation can be a common problem during winter, especially on older windows. Excess moisture can lead to mold, mildew, and wood rot.

  • Monitor humidity: Keep indoor humidity levels between 30–50% to minimize condensation.
  • Ventilate properly: Use exhaust fans in kitchens and bathrooms, and open windows occasionally to allow airflow.
  • Wipe down surfaces: Regularly check for condensation and wipe down any moisture that forms on glass and sills.

Preventing condensation protects your windows, doors, and interior surfaces from long-term damage.

6. Schedule Professional Maintenance

While many winter maintenance tasks can be done yourself, professional inspections ensure your windows and doors are winter-ready.

  • Expert inspection: Technicians can identify hidden issues, like air leaks, frame damage, or faulty seals.
  • Repairs and upgrades: If necessary, they can repair, replace, or upgrade your windows and doors to improve energy efficiency and performance.

Professional maintenance extends the life of your windows and doors, ensuring they perform optimally throughout the season.
