Installing uPVC windows in your home is a sensible, long-lasting upgrade. They are energy-efficient, secure and weather-resistant, and they also have a clean and modern look, which makes them ideal for the Irish climate. Whether you live in a quiet suburb like Rathgar or a coastalregion like Sutton, high-performance uPVC windows can enhance your comfort and lower your energy bills.
But uPVC windows come with a ‘maintenance-free’ label, which does not reflect the reality. They don’t need any maintenance, well, very minimal indeed. Like anything else in your house that’s subject to the elements, they like to be looked after. The good news? The uPVC solution to keeping your windows looking polished and brand new for more than 20 years does not involve pricey chemicals or expert knowledge, just the right method and a bit of consistency.
The Secret to Cleaning uPVC Frames
One of the largest selling points for uPVC windows is their bright, clean look. However, everyday dirt, traffic pollution, pollen and salt air can eventually haze the surface, particularly in urban locations like Rathgar or Swords.
There’s no need for strong chemicals or specialist cleaners. As a matter of fact, powerful solvents may discolour uPVC and even deteriorate its surface.
The most gentle way:
- Open the window and brush or vacuum loose dirt from the inside and outside.
- Mix a little warm water with mild dish soap.
- Wipe frames gently with a soft cloth or sponge.
- To prevent water spots, dry with a clean, lint-free cloth.
Cleaning your frames twice a year prevents tenacious staining and surface “pitting” – a process by which dirt is slowly driven into the plastic. Regular cleaning also helps maintain that crisp, white finish homeowners love.
How to Clean Glass Without Streaks
Vintage windows may be more prone to streaks and condensation. Compared to newer windows with double panes of glass, many older houses, especially those with single-pane windows, get condensation forming on the glass and may be subject to more streaks and dirt.
Good double and triple glazing is extremely clear and well insulated – if the glass is clean. On the other hand, living in a green patch in the Dane or a lot of trees in Clontarf, you would be accustomed to the tree sap, dust and bird droppings obscuring your sight really fast. Vehicle Cleaning.
Tips for Streak-Free Glass
Away from direct sunlight, Heat makes the cleaning solution dry too fast, and this causes streak marks on windows glass.
- Microfiber cloths – They are better at picking up dirt than paper towels, and don’t leave lint behind.
- Try a natural solution – When it comes to getting rid of grease and stains, a 50-50 combination of white vinegar and water really dries the job.
Loose hardware can cause pressure to be uneven on the mechanisms inside and result in windows being difficult to open and close, more so when you live in windy Irish winters. Smooth running is guaranteed with regular service and the lock serving for many years.
Maintaining Moving Parts and Hardware
Your window frames can look great, but they will perform best if you consider what you don’t see: your hinges, handles, and locking mechanisms. These parts are subjected to daily wear and tear and are especially at risk in coastal areas such as Howth, where the salty air speeds up the rate of corrosion.
Keep Everything Running Smoothly
- Lightly oil or silicone spray the hinges and locks.
- Oil every six months.
- Make sure handles and striker plates are tightly screwed.
Unfastened hardware can cause uneven pressure to be applied to the internal mechanisms, making it more difficult to open and close windows – particularly during windy Irish winters. Routine maintenance of the car ensures a hassle-free ride and a secure future for your children.
Checking Seals and Drainage Holes
At the bottom of every uPVC window frame, there are tiny drainage holes formed to make rainwater escape. In areas of heavy rainfall like Sutton, they can get clogged with moss, leaves and dirt.
What to Do
- Inspect drainage holes annually
- Clear blockages using a toothpick or thin wire
- Check rubber seals (gaskets) for cracks or dryness
Wipe seals with a damp cloth and put a little silicone grease on if they are a bit stiff. Vigorous seals keep heat in, prevent drafts, and keep moisture out, all of which are important for energy efficiency and comfort.
What to Avoid: Common uPVC Window Mistakes
Sometimes, cleaning with good intentions does more harm than good. To prevent long term damage to your windows and save yourself the trouble of replacing them, here are some common mistakes you should stay away from:
- No scouring pads or steel wool – these scratch the surface and hold grime
- Do not use bleach or solvent based or ammonia based cleaners on the frames.
- Don’t use pressure washers – the high pressure may damage the seals, and you end up with getting condensation inside your walls.
Killing the bacteria is important and requires patience and gentle cleaning, which is preferable to more drastic methods of cleaning.
