First of all, this is not a Marvin problem. It is an installation issue. You must have something going on to where the installer backed out. I would take their recommendation for an installer and move forward.

+1. Has nothing to do with Marvin, just a contractor that doesn't want the job for some reason. Maybe he quoted it too low or something.... As eastbay said, next step is to call another window company or two.

They never did give me a quote on the installation, just said they were not able to do it. there is only one other Marvin dealer near by and I have called them. I know there is a lumber company that carries Marvin. Is it ok to get a quote from them ? And, does anyone know if Marvin's warranties are valid if installed by private contractors and not their own ?
Thank you,

If the lumberyard has Marvin displays, I would get a quote from them. If they simply say, they can get Marvin I would be a little more hesitant.
Marvin warranties are product oriented and not necessarily related to the installation. There are no issues with using non-factory approved installers. Just avoid the lowest bid and go with a competent installer and you should be fine.

the installer/ company might have saw or sensed something he didnt feel comfortable with and decided to walk.

I think you're correct in they're finding something with one of the windows. I think it is the semi circle installed over a double hung. They could not figure out how to do it and have it look right inside as well as out. What is there now is a Pella double hung with a Brosco semi circle over it. The semicircle is rectangular inside and a semicircle out.....don't know how else to desribe it. It was installed 35 years ago , so if one is familiar with Brosco from that era, you would understand.

Half round windows are installed everyday and I doubt that is the reason he bailed on giving you a price or being able to take your project on. It is more than likely he cannot do it in your time frame or something along those lines.

There was no set time frame mentioned. I still think it was this window that had them puzzled, but they also kept changing the prices on the windows .....this after we were plain in telling them it was to be a full replacement , including frame. I don't know whether someone didn't do their homework, or they just didn't want the job. I think if that was the case, they should have been more up front with us . The nearest Kolbe dealer is quite some distance away to see their product , but that is the way we are looking now.

Kolbe price should be a little cheaper just make certain to get the Kolbe Ultra series as these are extruded aluminum clad and not roll form (which you do not want)

Thank you all. Will let you know how we eventually make out.
