Part 2: complaint close-ups!
If you are sitting at certain angles to the window, you can see right through the spacer. If you are not seeing through it, you are seeing the dark plastic (at least they could have made it white to match the rest of the material of the windows).
I don't know why we didn't notice this on the samples at the supply
company, but possibly it was that we were looking at completely
different windows because of course these were custom designs. But on the Milgard Website, their drawing of this particular detail showed a thick block, as in solid-looking, not a thin piece, so I felt it was false advertising. For these kinds of windows, and between the glass, I understand why it has to be this way, but we were still disappointed.
We had to swallow that disappointment, because there was nothing anyone could do about it. But the next thing did get fixed!
I complained to Milgard and they sent a repairman out who filled in all these gaps at the tops of all the windows. He even said he would get us some missing handles, and he adjusted some of the window hardware so that they would not be so loose to crank. He looked at some screens that appeared damaged. We felt like it was great customer service!
However, he stopped answering texts about sending the handles (we still don't have them) and was never heard from again, at least by us! This post reminds me that we got so busy with the rest of the house, I never got to back to Milgard about those handles or the screens that needed replaced...
Overall, I think Milgard is very generous with their lifetime guarantee, and the windows are solid and after all we would probably say very good quality. We were disappointed at what we think is a design flaw of the inner piece, but were pleased that they came out to fix the manufacturing flaw.
