Drafts can be a pesky problem, especially when you’ve invested in uPVC windows expecting them to keep your home warm and energy-efficient. Over time, even the best uPVC windows can develop drafts, which can lead to higher energy bills and uncomfortable living conditions. Luckily, fixing drafts in uPVC windows is usually straightforward and can often be done without professional help. In this guide, we’ll walk you through the common causes of drafts in uPVC windows and provide practical solutions to fix them.
Common Causes of Drafts in uPVC Windows
Before diving into the solutions, it’s important to understand why your uPVC window might be letting in a draft. Here are some common causes:
- Worn or Damaged Seals: The rubber seals around the edges of your uPVC windows are designed to create an airtight barrier. Over time, these seals can become worn, cracked, or damaged, allowing air to pass through.
- Misalignment: Windows can become misaligned due to regular use, improper installation, or building movement. A misaligned window may not close properly, leaving gaps for drafts to enter.
- Faulty Hinges or Handles: If the window hinges or handles are damaged or not functioning correctly, the window may not close tightly, leading to drafts.
- Ageing uPVC: While uPVC is known for its durability, it can still wear out over time. The material may warp or degrade, creating spaces where air can seep through.
How to Identify Drafts
The first step in fixing a drafty window is identifying where the draft is coming from. Here’s how you can do that:
- Visual Inspection: Look closely at the edges of your window for any visible gaps or damage. Check the seals and the frame for signs of wear and tear.
- Candle Test: Light a candle and hold it near the window edges. Move it slowly along the seams and corners. If the flame flickers, you’ve found a draft.
- Paper Test: Close your window on a piece of paper. If you can pull the paper out without tearing it, the window may not be sealing properly, indicating a potential draft source.
How to Fix Drafts in uPVC Windows
Once you’ve identified the source of the draft, you can proceed with the appropriate fix. Here’s a step-by-step guide to fixing common issues:
1. Replacing Worn Seals
Worn or damaged seals are one of the most common causes of drafts in uPVC windows. Here’s how to replace them:
- Remove the Old Seals: Gently pull away the old seals from the window frame. You may need to use a flathead screwdriver to pry them off.
- Clean the Area: Use a soft cloth to clean the area where the old seals were. Ensure there’s no residue left behind, as this can affect the new seals’ adhesion.
- Install New Seals: Measure the length of the window edges and cut the new seals to size. Press the new seals firmly into place, ensuring they fit snugly along the entire edge.
2. Adjusting Window Alignment
If your window is misaligned, you can often fix it by adjusting the hinges:
- Open the Window: Fully open the window to access the hinges.
- Adjust the Screws: Use a screwdriver to tighten or loosen the screws on the hinges. You may need to adjust both the top and bottom hinges to get the window to align properly.
- Check the Fit: Close the window and check if the alignment has improved. Repeat the adjustment process until the window closes tightly.
3. Repairing or Replacing Hinges and Handles
Faulty hinges and handles can prevent your window from closing correctly:
- Inspect the Hinges and Handles: Look for signs of wear, rust, or damage. If they are visibly damaged, they may need to be replaced.
- Lubricate Moving Parts: Sometimes, a simple lubrication can solve the problem. Use a silicone-based lubricant on the hinges and handles to improve their functionality.
- Replace if Necessary: If lubrication doesn’t work, you may need to replace the faulty parts. Purchase replacement parts that match your existing hardware and follow the manufacturer’s instructions for installation.
4. Dealing with Ageing uPVC
If your uPVC windows are older, they may need a bit more attention:
- Consider Reglazing: If the window pane is loose or damaged, you may need to reglaze the window. This involves removing the old glazing and installing a new pane.
- Professional Assessment: If your uPVC windows are very old or severely damaged, it might be time to consider replacement. A professional assessment can provide guidance on whether repairs or replacement are the most cost-effective option.
Additional Tips for Preventing Drafts
- Regular Maintenance: Regularly inspect your windows for signs of wear and tear. Keep the seals clean and lubricate the hinges and handles to ensure smooth operation.
- Install Draught Excluders: Draught excluders are an affordable and effective way to reduce drafts. They can be installed along the edges of windows and doors to provide an additional barrier against cold air.
- Double-Check Installation: If you’re having new windows installed, make sure they are fitted by a professional. Poor installation is a common cause of drafts, and proper fitting will ensure your windows are as energy-efficient as possible.
