I have had small issues with my windows purchased from Willmar. Handle knobs coming off, windows sticking and very hard to open. Haven't had any seal issues yet. Windows installed in 1998 in Burnaby BC.

Mine too. They all lost their seal and fogged up. Company says sorry, no warranty.

we purchased willmar windows for our home in 1996 and have had to replace almost all of them due to seal loss. They were very expensive to buy and very poor. Right now we are having to look at replacing some that were already replaced under warranty but now that the warranty has run out, it will be at our expense to do so.
