As the seasons change, so do the demands on your home’s windows and doors. Whether it’s the sweltering heat of summer or the cold of winter, your windows and doors play a vital role in maintaining your comfort and energy efficiency. Over time, wear and tear can take a toll on windows and doors, potentially leading to air leaks, condensation, and decreased energy efficiency.

In this blog, we’ll discuss the importance of conducting seasonal window and door checks and offer a comprehensive checklist to help you evaluate whether you need replacement windows. Plus, we’ll discuss how proactive maintenance can extend the life of your windows and doors while ensuring maximum energy savings.

How windows and doors suffer damage over time

Windows and doors are subjected to various environmental stresses throughout the year. Understanding how they can suffer damage over time is the first step in maintaining your home’s comfort and energy efficiency.

Weather exposure

Extreme temperatures, moisture, and UV rays from the sun can cause materials to expand, contract, fade, or deteriorate. Over time, this exposure can lead to cracks, gaps, or warping in the frames and seals of windows and doors.

Wear and tear

Daily use, especially in high-traffic areas, can lead to wear and tear on doors. Door hinges, handles, locks, and weather stripping can suffer under heavy use. Windows are also susceptible to damage, notably if frequently opened and closed.

Sealing and insulation

The seals and insulation around windows and doors can degrade over time, allowing drafts, air leaks, and moisture infiltration. Degraded seals mean drafts, which results in higher energy bills.

The checklist

To ensure your windows and doors are in optimal condition, conducting seasonal checks is essential. Here’s a comprehensive checklist to guide you.


  • Examine the frames: Inspect the frames for signs of cracks, warping, or decay. Look for any visible damage that might affect their integrity.
  • Check for air leaks: On a windy day, run your hand along the edges of the windows. If you feel drafts or air movement, it indicates possible leaks that need sealing.
  • Inspect the seals: Check the weather stripping and seals for wear and tear. Replace any damaged or deteriorated seals to maintain a tight seal.
  • Check exterior caulking: Breaks in exterior caulking can contribute to both air and water leaks.
  • Clean and lubricate: Clean the tracks and lubricate the moving parts like hinges, handles, and locks to prevent sticking and ensure smooth operation.
  • Test for condensation: Look for condensation between double or triple-pane windows. If present, it indicates a failed seal, reducing the window’s energy efficiency.
  • Evaluate the glass: Inspect the glass for cracks, chips, or fogging.


  • Check the threshold: Examine the threshold for signs of wear and tear. Ensure it forms a tight seal when the door is closed to prevent drafts.
  • Inspect weather stripping: Like windows, check the weather stripping around the door frame for damage. Replace any worn or damaged weather stripping.
  • Test the locks: Ensure all locks, including deadbolts, latch smoothly and securely. Lubricate if necessary to prevent sticking.
  • Examine hinges: Inspect door hinges for loose screws or visible damage. Tighten screws or replace hinges as needed.
  • Check for drafts: On a windy day, hold a candle near the edges of the door. If the flame flickers, it indicates potential air leaks that require attention.
  • Evaluate the door material: Depending on the door type (wood, fibreglass, steel), look for signs of rot, warping, or rust. Address any issues promptly to prevent further damage.

If you find this list a little daunting, you can engage a local professional to make an Energy Star Home Performance Assessment to get a solid idea of the efficiency of your home.
