Pjs I think i was quoted by the same company as you. After everything was said and done, the price was MUCH higher. They needed to add lowE/ argon, capping, proper insulation, and debris removal. I guess the initial cheap price is to get you hooked? The $189 per window companies are notorious for this, plus they sell complete garbage anyway. Also, some company salesmen are clueless and make major pricing mistakes. When i saw the cheap prices you were quoted, they were almost the same as mine then of course they jumped up. i would much rather use a company that is upfront and i would be happy to pay more for quality( within reason). I did go with another company that sold Okna, they were upfront and very professional. I paid about 582 per window for the okna 800 series. The 500 would of been 530 per. The other prices i see quoted by others seem much more realistic and were basically in line with mine. NJ seems to have the same pricing as my state; similar demographic.

With all of the variables involved I would agree with Uneeda. An apples to apples comparison will speak volumes, but that said, I can't really see any circumstance where this is NOT a reasonable price. A 5 panel bow takes up a big chunk of that amount, and the remaining "per window" cost sounds very reasonable. Sounds like a great deal on a great window if you feel good about the installation company.

Forgive the blunt commentary by Windexo, but as WoW stated, it is with a high degree of regularity that highly respected contractors do poor window installations. It is really a specialty service, much like tile, or auto body, or any number of things. You wouldn't hire a highly respected body man to replace the motor in your car because he was a well-regarded "car guy", or go to a podiatrist for persistent migraines. For some reason it is a widely held belief that that "carpenters" pretty much do everything, which is generally not true. .... and this is all speculation of course. Perhaps your connection is an expert at installing windows and there is nothing to worry about... I'd recommend that you read through this article and have a lengthy conversation about how his procedures will either mimic or vary from what is described. http://www.finehomebuilding.com/how-to/install-replacement-windows-and-flashing-correctly.aspx

The Okna 600 is a better window and I agree, its nicer looking than castle. I have nothing against castle windows, their window is ok but just not up there with okna or some of the other higher end windows. Castle can be pushy with their sales tactics and tend to put too much emphasis on their warranty. A good window and a good installer is the best warranty you could get in my opinion. Most windows are a limited lifetime warranty which is good and even better if its transferrable. A labor warranty of 2 years or more is fine. If the installer is good, a 5 minute labor warranty is plenty.
