Window frame maintenance: your questions answered

How do I clean window frames?

uPVC Windows

  1. Use a bucket of soapy water to wipe it down
  2. If you’re feeling eco-friendly you can replace the soapy water with a 3 to 7 ratio of  vinegar and water solution. Spray on and leave for a few minutes before wiping off
  3. Wipe dry with a clean tea towel

Aluminium Windows

  1. Wet your frames first of all
  2. Douse with a specialised aluminium cleaner, following the package instructions
  3. Wipe down your frames from top to bottom
  4. Rinse with fresh water
  5. Wipe dry with a clean tea towel

Wooden Windows

If they are mouldy:

  1. Buy a commercial mould spray
  2. Follow the package instructions
  3. Your windows will then be as clean as new!

If they are not mouldy:

  1. Wipe away dust on the window frame with a lint-free rag with some wood wax or preservative on it
  2. If they are varnished you can wash them with warm soapy water
  3. Be sure to maintain them according to manufacturer instructions (this usually includes a sealer or preservative every year or so)

How to paint window frames outside and in: 

Give your windows some new life with a lick of paint! This is a cheap way to brighten up your interior and add some curb appeal if you do the exterior frames too. Keep in mind that wooden windows are most ideal to be painted, uPVC can be painted in some circumstances and with some preparation. Aluminium window frame painting on the other hand is a no-no. Here are some instructions to help you complete this project you could do in a weekend:


  1. Do not paint when it’s hot and sunny outside (or rainy, for obvious reasons)
  2. Clean the areas you are going to paint before beginning
  3. Make sure to mask your surrounding areas and prepare well!
  4. With casement windows, keep them open and paint all around the sash
  5. For sash windows, raise the lower sash and drop the upper sash before painting all around the sides of the exposed sash
  6. Paint the window sills and casing
  7. After these parts are dry you can paint the trim (that connects the frame to the wall)Leave to dry before removing the masking tape


  1. Clean the areas you will paint
  2. Remove the catches and stays so you won’t paint over them
  3. Keep your window open with a temporary stay (a sturdy wire on to a nail)
  4. Lightly sand the area you will paint (unless they are uPVC – they need special treatment)
  5. Use a brush to clean off dust and dirt
  6. Place masking tape around the area to be painted
  7. After painting leave to dry completely before removing masking tape

What causes mould on window frames?

Mould likes damp environments. If your windows are prone to collecting condensation then that is probably the reason. A good way of avoiding this is keeping your house as dry as possible by maximising ventilation, avoiding hanging up wet laundry inside and potentially investing in a de-humidifier.

What colour to paint window frames?

This all depends on the colour of your home inside and out! Many people paint the interior one colour and the exterior another, to match the different colours that we see from each side. In general people go for either natural colours (shades of brown, grey and black) or for white. However creativity is encouraged as long as your home is not a period construction or in a protected area, in which case you may have limited options.

What are window frames made out of?
