How to Repair a Hole in uPVC Window Frame?

I am not sure about which is the best way to fill holes in UPVC window frames but I can suggest a few effective ones. You can always use PVC filler, but as an alternative, try using a hard wax filler, epoxy putty or sealant. To fill holes in UPVC window frames, apply hard wax filler for smaller holes, pressing and smoothing it. For larger holes, you can use epoxy putty or a UPVC-specific sealant.

How to Fill Holes in uPVC Window Frames?

There are many ways to repair or fill a hole in the UPVC window frame. Here are the two most effective ways I can suggest:

Hard Wax Filler:

Hard wax filler is the best to repair or fill small holes. It even comes in various colours, so you can match it with your window frame shade easily. You just have to melt the wax using a filler applicator or specialised tool, then press it into the hole and smooth it down with a scraper to get an even surface.

Epoxy Putty or Sealant:

For larger holes, you can use epoxy putty or UPVC-specific sealant. Simply mix the epoxy putty as instructed in the packaging and push it firmly into the hole. You can also consider applying sealant with a caulking gun for smaller holes and smoothing it with a putty knife or your finger. Both options provide a long-lasting fix, so opt for whichever you think is better.

These are my suggestions on how to repair a hole in uPVC window frame and I hope these will be useful to you.
