Some people swear by it, others not so much. I fall into the not so much category as it really a crap shoot if it will work and hold up well.

It's a bandaid on a bigger issue and it will keep coming back, waste of time and money. Fix it right and replace the glass.

Not sure I would replace a piece of glass in an 18 year old Hurd window though FT?

I agree that the technology is a bit unproven to be claiming that it is a one stop fix.

Curious why you wouldn't replace the thermal pane, WonW? The windows have been fine except for the random condensation...

Hopesprings,

You cannot just replace one pane of glass, the entire IGU needs to be replaced. My comment as to whether I would not be sure about replacing an IGU in an 18 year old Hurd has to do with what I usually see as the observed condition of 18 year old Hurds.

If the windows are otherwise in good shape, replace the IGU.

You are certainly in the minority though with having 18 year old clad wood windows being in good shape.

Props to you for obviously maintaining them if that is the case.

Thanks, WonW, but I can't take credit. They're pretty solid from what I can see. We replaced our siding last year and found many of the edge flanges cracked, so our contractor replaced all of them. I am really hoping these windows hold up a while longer...like until I've sold this house at some indeterminate future date. :)

Keep them well caulked and painted and you should be fine.

Keep the bushes cut back from in front of them as well.

If they haven't failed yet, they are probably very solid and should last a good long while.

Windows, poorly engineered units, usually fail in the first 7-10 years.

Repairing blown window seals is great,,,,if you are the guy that charges 100's of dollars to do it.
It will not work, the seal material that is bonded to the glass is not bonded anymore. nothing will fix that.
Total crooks
