Plastic windows are a popular choice for homeowners, offering durability, energy efficiency, and low maintenance. However, like any other component of your home, they require regular upkeep and occasional repairs to keep them functioning at their best. In this article, we’ll explore some tips and techniques for maintaining and repairing your plastic windows.

Maintenance Tips

Regular maintenance is essential for keeping your plastic windows in good condition. Here are some tips to keep in mind:

  1. Clean the windows regularly: Dirt and grime can build up on the windows over time, making them look dirty and reducing their efficiency. Clean the windows regularly using a mild detergent and a soft cloth. Avoid using abrasive cleaners, as they can scratch the surface of the windows.
  2. Inspect the seals: The seals around your windows can deteriorate over time, allowing air and water to leak into your home. Check the seals regularly and replace them if you notice any signs of wear or damage.
  3. Lubricate the moving parts: The moving parts of your windows, such as the hinges and handles, can become stiff and difficult to operate over time. Lubricate these parts regularly with a silicone spray to keep them moving smoothly.
  4. Check for damage: Inspect your windows for any signs of damage, such as cracks or chips. Address any damage as soon as possible to prevent further problems from occurring.
