UPDATE October 2018: All fixed and I have to add that in my humble opinion this is one of the best slider doors on the market. When we took the old door off to fix the glass the rollers were still super smooth. The frame was perfectly fine after 8 years of usage with two dogs going in and out constantly. We updated our lock set and that is built to last too! The staff at VIwinco went out of their way to help us out, very good people and I thank them.

UPDATE July 2018: I have changed my review to 5 stars. We eventually worked this out with VIwinco and they are helping us fix the door. They stand by their products. The door was always built like a tank, it's why I bought it originally. I will gladly fix this door frame with new glass and a new lockset. Unfortunately I think my poor communications and follow - up with the company are mostly to blame for it taking this long. My wife eventually made some calls and stuck to it. Very very helpful people working there now.
Original review: ----------
We bought a Viwinco slider door from a contactor back in 2010 to replace a builder grade slider. The window seals began to fog in colder temps......
