What Problems Will You Face If You Install uPVC Doors And Windows?

Take a look at the common challenges associated with uPVC, along with comprehensive solutions offered for every problem.

1. Difficulty in Opening or Closing the Window:

When faced with challenges in operating your uPVC windows, the culprit is often misaligned hinges or worn-out components. 

Solution: Start by adjusting the hinges to ensure proper alignment. Additionally, replace any worn-out parts and lubricate the moving elements. Consistent and regular maintenance is crucial to prevent future issues and guarantee the smooth functionality of your windows.

2. Leaky uPVC Windows:

Leaks around uPVC windows typically result from damaged seals or gaps. Dealing with a leaky uPVC window is a common challenge for homeowners in Chesterfield, often leading to confusion about the best steps to take.

Solution: To address this issue, thoroughly inspect the window’s seals and weatherstripping. Replace any damaged components to establish a reliable and watertight seal, preventing leaks and potential water damage to your property.

3. Condensation Buildup:

Interior condensation on uPVC windows is a natural consequence of temperature fluctuations. When warm indoor air meets the cooler glass surface, moisture condenses, forming water droplets.

Solution: To tackle this problem, enhance the ventilation in the affected areas. Consider upgrading to double-glazing for improved insulation, or use anti-condensation products to effectively manage and reduce condensation buildup.

4. Cracked or Damaged uPVC Window Frames:

Cracks in uPVC window frames can develop from exposure to harsh weather conditions or physical damage. 

Solution: To address this, fill small cracks with suitable sealants as a temporary fix. For more extensive damage, seek professional assistance for a thorough inspection and, if necessary, opt for frame replacement to maintain the structural integrity of your windows.

5. Problems with Locks:

If you encounter difficulties in locking or unlocking your uPVC windows, the issue may lie in misalignment or faulty lock mechanisms. 

Solution: Begin by adjusting the alignment to ensure a proper fit. Replace any locks that show signs of wear or malfunction. For more complex lock issues, consult with a professional to ensure a comprehensive and effective resolution.

6. Discolouration:

Discolouration of uPVC windows is a common issue caused by prolonged exposure to sunlight. To prevent this problem, implement a regular cleaning and maintenance routine. 

Solution: In cases of existing discolouration, consider professional cleaning or restoration services to revive the original appearance of your uPVC windows and maintain their aesthetic appeal.
