silicon sealer has shrunk around UPVC windows

Postby sockpuppet » Sun Jul 27, 2008 5:56 pm

The silicon sealer around my UPVC windows has shrunk leaving gaps.

The window units are fine so I would like to remove all the old sealant and replace with new, is there any special tools or chemicals I can or should use to do this? I have 9 windows to re-seal (white frames)

Hi SP,

There is a silicon digester out there but its expensive I believe. Best way is sharp stanley knife to cut out all old sealant, clean then reseal with a GOOD quality sealant for windows.
