The complete guide for the care and maintenance of PVC windows in the autumn season

PVC windows are a popular choice for many homeowners due to their durability, energy efficiency and ease of maintenance. However, to enjoy all the benefits of these windows in the long term, it is essential to pay particular attention, especially in the autumn season. Here is the complete guide for the care and maintenance of PVC windows during this period.

Complete Guide to PVC Window Maintenance in Autumn

PVC windows are a popular choice for many homeowners due to their durability, energy efficiency, and ease of maintenance. However, to enjoy all the benefits of these windows in the long term, it is essential to pay particular attention, especially in the autumn season.

Here is the complete guide for the care and maintenance of PVC windows during this period:

1. Cleaning the PVC Profile and Glass

Autumn brings rain, wind, and debris (like leaves and pollen), making a thorough cleaning necessary.

• Profiles (Frames): Use a mild solution of soap and warm water with a soft cloth or sponge. Avoid harsh chemicals, solvents, or abrasive cleaners, as these can damage the PVC surface and lead to discoloration. Clean all visible parts of the frame, paying close attention to the bottom sill where water and dirt collect.

• Glass: Clean the glass using standard window cleaner or a vinegar and water solution. Ensure no residue is left behind, as this can attract dirt.

• Seals and Gaskets: Gently wipe down the rubber seals (gaskets) using a damp cloth. Check for any hardening, cracking, or shrinkage. Keeping these supple is crucial for maintaining the window’s airtight seal and energy efficiency.

2. Draining and Ventilation System Check

Proper drainage is vital to prevent water damage and mold growth.

• Drainage Channels: PVC windows have small drain holes (weep holes) located on the bottom of the external frame. These are designed to allow any water that breaches the exterior seal to drain out.

  • Action: Clear these holes using a small, non-metal object (like a toothpick or soft brush) or a gentle puff of air. Clogged weep holes can cause water to pool inside the frame, leading to operational and moisture problems.

• Ventilation: Briefly open and close the windows to ensure the ventilation settings (if applicable) are working properly. Ensure seals are fully compressed when the window is closed to maintain insulation.

3. Hardware and Mechanism Lubrication

Autumn is the perfect time to lubricate moving parts before cold weather makes the hardware stiff.

• Hinges and Moving Parts: Apply a silicone spray or acid-free technical lubricant to all visible hinges, locking mechanisms, and moving metal components.

• Action: Work the window open and closed several times after lubrication to ensure the product is evenly distributed. This smooth operation reduces wear and tear, prolonging the life of the hardware.

• Tightness Check: Inspect all screws and mounting elements. If a handle feels loose or the window rattles when closed, gently tighten the screws. However, do not over-tighten, as this can warp the PVC.

4. Inspecting for Damage and Airtightness

The primary goal of autumn maintenance is preparing the window for winter.

• Visual Inspection: Examine the PVC profile for any signs of physical damage, deep scratches, or gaps in the seal between the frame and the wall.

• Airtightness Test: On a windy day, move a burning stick of incense or a thin piece of paper along the edge of the closed window. If the smoke wavers or the paper flutters, you have an air leak.

• Action: If you find small gaps or compromised seals, apply a specialized, weatherproof sealant around the exterior perimeter. This prevents moisture ingress and maintains the window’s crucial thermal barrier.

By dedicating time to these simple but essential tasks in the autumn, you ensure your PVC windows remain durable, operate smoothly, and continue to provide optimal energy efficiency throughout the harsh winter months.
