Leaking black sealant


Postby smander » Mon Mar 22, 2010 11:52 am

Hi,

After a bit of advice. Moved into 11 year old property and have noticed that the black sealant in the windows is either "leaking" down the window or there is a noticeable gap where the sealant has "shrunk". Windows are wooden framed double glazing. Any help gratefully appreciated and how to resolve these issues.

Cheers

smander,
Forum members will need more information.
Are you referring to the black sealant between the panes of the double glazing units or the sealant on the outside.

I think I have exactly the same problem as smander.

The black beading I am referring to is the black rubber type seal that is on both inside and outside of window and bridges the gap between the glass sealed unit and the Upvc window frame.

Any ideas what its proper name is and where replacement can be obtained?

adobbing,
The glazing seal strip on the inside of the windows can be replaced easily, the problem will be finding the correct section - it must be a tight fit for security reasons.
The outside seal is part of the glazing beads and your chances of getting a replacement are very slim - see if fitting a larger section inner glazing seal strip will solve the problem.

Hi,

The Black seal on the Timber windows between the Glass and the Bead or back rebate is probably Flexistrip. A Butyl rubber strip that is rather like putty on a roll. Unfortunatley some glass cleaning chemicals can make it soft and it then leaks out . Try buying some Butyl Glazing compound from your local glass shop and using a wide stripping type knife, scrape the Butyl into the gaps and smooth off.
