Cracked uPVC Cill

Post by knights » Sat May 19, 2018 5:37 pm

Hi

I have cracked the corner of a bay window cill (Really I won't go into what I had done). Looking at getting this repaired using Konig repair system (Hard wax system) but they are saying the crack is not stable enough to be repaired due to movement. Does anyone have any ideas or know of products which will sort this out? I have had a uPVC company out who said the only way was to replace the whole window. Any alternatives?

Best regards Ray

That's interesting as you can't "glue" a new bit on top as it would (probably) stop the opening windows from opening. And having watched windows being made form scratch they do start with sides bottom and top welded together, I would say you would have to change the whole window :dunno:

You might try a "window doctor" to see if they can suggest anything, but,.........

Then again, picture might help?
Fret not, a forum is a collection of opinions. Above, are mine.

Which is correct? Metre or Meter? Click the link to find out more.

Working on anything electrical? have you got a multi meter? why not? Would you hit a nail with a shoe?

Does the crack go all the way through? If you can access from the bottom you could make a good patch to strengthen it. Going to be difficult to repair the top though due to the grain pattern. Guess it all depends on how good you want it to look.

The only way to change the cill would be to remove the window, the cill is a separate part that the frame section sits on, it shouldn't need a whole new window.
One day it will all be firewood.

Sounds about right. No need for a new frame/glass, remove existing glazing and frame, renew sill, replace old/existing frame and glazing. days work tops.
