My parents house had double glazed windows installed about 25 years
ago. The windows (aluminium frames with a factory applied white
finish) are in excellent condition, but the sealant used to 'point' the
small gap between the window frame and the wall (standard red brick) is
starting to deteriorate and crack on some of the more exposed windows.
My guess is that the gap between the window and the is very small.
The 'pointing' is triangular shaped.

My question is what type of sealant to use to re-point the gap. I am
confused with all the variations of Silicon (?sp), butyl compounds,
putty etc. etc. The existing sealant is white, has very little
flexibility (although that could be age related). As far as I know it
was never painted, so i don't think it was putty. My understanding is
that putty needs to be painted to stop it drying out too much.

Any help at identifying the correct sealant would be appreciated. Most
of the previous posts discuss sealing the glass to the window frame -
not the frame to the wall.

Thanks
