DIY Upvc Doors & Windows Maintenance Tips: Extend the Life and Performance of Your Simta Astrix Products.

At Simta Astrix, a leading manufacturer of doors and windows, we take pride in crafting high-quality uPVC doors and windows designed for lasting durability and performance. However, even the best products benefit from a little TLC to ensure they continue to operate smoothly and efficiently for years to come.

This comprehensive DIY uPVC doors and windows maintenance guide equips you with the knowledge and steps needed to keep your Simta Astrix products looking their best and functioning flawlessly.

Why is uPVC Maintenance Important?

Regular maintenance of your uPVC doors and windows offers a multitude of benefits that go beyond just aesthetics. Here’s why taking care of your Simta Astrix products is essential:

  • Enhanced Longevity: Proper care prevents premature wear and tear, extending the lifespan of your uPVC doors and windows by several years. This translates to significant cost savings, as you won’t need to replace them as frequently.
  • Improved Efficiency: Clean and well-lubricated mechanisms ensure smooth operation, minimising friction and resistance. This, in turn, improves the energy efficiency of your doors and windows, potentially leading to lower energy bills.
  • Maintained Aesthetics: Regular cleaning keeps your uPVC doors and windows looking fresh and vibrant, enhancing your home’s curb appeal and adding value to your property.
  • Trouble-Free Operation: By addressing minor issues early on, such as sticking doors or worn seals, you can prevent them from escalating into bigger problems that require professional repairs.
  • Environmental Benefits: Extending the lifespan of your uPVC doors and windows reduces waste and the environmental impact associated with manufacturing new products. This makes proper maintenance a responsible choice for a greener future.

Essential Tools and Materials for uPVC Maintenance:

Before we delve into the specifics, let’s gather the necessary tools and materials for effective uPVC maintenance:

  • Bucket
  • Warm water
  • Mild dish soap or liquid detergent
  • Soft microfiber cloths or sponges (avoid abrasive materials)
  • Lint-free cloths for drying
  • Silicone spray (for lubricating hinges and locks)
  • Optional: White vinegar (for stubborn stains)
  • Talcum powder (for lubricating door and window seals)

Step-by-Step Guide to Maintaining Your uPVC Doors and Windows:


  • Frequency: Clean your uPVC doors and windows at least twice a year, or more often if exposed to harsh elements like sea spray, heavy dust, or industrial pollution.
  • Solution: Mix a few drops of mild dish soap or liquid detergent with warm water in a bucket. Avoid harsh chemicals, bleach, or abrasive cleaners, as they can damage the uPVC surface and compromise its weather resistance.
  • Cleaning Process: Dip your microfiber cloth or sponge into the cleaning solution, wring it out to avoid dripping, and wipe down the entire uPVC frame, both inside and outside. Pay close attention to corners and grooves where dirt and grime can accumulate.
  • Glass Cleaning: For the glass panels, use a separate clean microfiber cloth dampened with plain water or a store-bought glass cleaner. Buff the glass dry with a lint-free cloth to prevent streaks and ensure a clear view.
  • Stubborn Stains: For stubborn dirt, grime, or hard water marks, you can create a cleaning solution with a 2:1 ratio of white vinegar and water. Apply this solution sparingly with a soft cloth, rinse thoroughly with clean water, and dry completely. Always test the vinegar solution on an inconspicuous area first to ensure it doesn’t discolour the uPVC surface.

Drainage Channel Maintenance:

The drainage channels located at the bottom of your uPVC door and window frames are crucial for proper water drainage. Clogged drainage channels can lead to water accumulation, which can damage the uPVC frame and promote mould growth.

  • Regularly inspect these channels for debris buildup, such as leaves, twigs, or dirt.
  • Use a soft brush or a piece of wire (not sharp) to clear any blockages.
  • Ensure the drainage holes are clear to prevent water from pooling around your doors and windows.


Moving parts like hinges and locks require occasional lubrication to ensure smooth operation and prevent squeaking noises.

  • Apply a light spray of silicone spray on the hinges and lock mechanisms of your uPVC sliding doors. Wipe off any excess spray to prevent dust and dirt from sticking.
  • For door and window seals, you can apply a light dusting of talcum powder to improve their flexibility and prevent sticking. Avoid using lubricants like oil or grease on the seals, as this can attract dirt and deteriorate the material over time.

General Maintenance Tips:

  • Seasonal Checks: During extreme weather conditions, like heavy rainfall or strong winds, perform a quick inspection of your uPVC doors and windows to ensure there are no leaks or drafts.
  • Hardware Tightening: Over time, screws and hardware on your doors and windows might loosen slightly. Tighten them periodically using a screwdriver, but avoid over-tightening, as this can damage the screws or the uPVC frame.
  • Avoid Harsh Weather: As much as possible, minimise exposure of your uPVC doors and windows to extreme temperatures. During very hot weather, consider using blinds or curtains to shield them from direct sunlight. This will help prevent the uPVC frame from warping or discoloration.

Additional Tips for Specific uPVC Products:

uPVC Door Maintenance:

  • Sliding Doors: Regularly clean the tracks of your sliding doors to remove dirt and debris that can impede smooth operation. You can use a vacuum cleaner with a soft brush attachment for this purpose.
  • Hinged Doors: Check the door alignment periodically. If the door seems misaligned and scraping against the frame, consult your Simta Astrix manual or contact a qualified professional for adjustments.

uPVC Window Maintenance:

  • Casement Windows: Ensure the opening and closing mechanisms of your casement windows operate smoothly. Look for any signs of friction or resistance, which could indicate worn hinges or damaged friction stays. Apply a light coat of silicone spray to lubricate these moving parts.
  • Awning Windows: Awning windows open outwards from the bottom. Regularly clean the hinge located at the top of the window frame and apply a light coat of silicone spray for smooth operation.

Troubleshooting Common Issues:

  • Sticking Doors or Windows: Over time, dirt accumulation or worn seals can cause your doors or windows to stick. Try cleaning the tracks or frames thoroughly. If the issue persists, consider replacing the seals. For sticking hinges, apply a light coat of silicone spray.
  • Drafts: Drafts can occur due to worn seals or improper alignment of the door or window sash. Inspect the seals for cracks or tears, and replace them if necessary. If the draft seems to be coming from the edges of the sash, consult a professional for door or window realignment.
  • Condensation Buildup: Excessive condensation on the interior surface of your windows indicates poor ventilation. Ensure proper air circulation in your home by opening windows regularly, especially during cooking or showering.

For more complex repairs or situations where you’re unsure about the cause of the problem, it’s always advisable to consult our professional.
