If you did not replace the bow yet then listen please. I am a contractor of 35 years. If this was my home. I would eliminate the existing bow window and replace it with a 4 pieces straight window. It will cost 50% less then a bow or bay and will give you better insulating value then a bow or bay window. I use 3 window companies Anderson, Marvin and Kurpiewski Windows Producer. Out of the 3 only Kurpiewski will fit you the best. They are fairly close to you located in New Jersey. Kurpiewski Windows produces very high quality virgin vinyl windows. They are very tough, good and long lasting windows. To buy from them you must go through there dealer network. Sue I am recommending for you a 4 pieces straight virgin vinyl window from Kurpiewski Windows Producer in New Jersey. Hope you get it done soon.

Hey There: If you want to use the seat in the window, your absolutely best option are bottom up - top down operating pleated blinds. With less than 1 inch in depth, they can be individually installed as inside mount and do not take away any room from your seat. They let you also manage light and privacy depending and dress up your windows. Feel free to visit us online at www.PleatedBlindsStore.com or give us a call...

I used to make custom Romans, however, I did buy wood blinds from Smith and Noble. Their customer service is really great. The strings broke on one of the blinds years later and they actually replaced it for free. Also, when I first ordered it, there was a small problem that was my fault, and they also took care of that for free. Highly recommend also. I also measured and installed myself, so can't comment on that part.
