Replacement Windows in Rochester NY

[JD DiGiacomandrea]

I am finishing a renovation on a property and recently learned how easy it is to replace windows. What I have found difficult is sourcing low cost replacement window. I purchased 2 of the windows I needed at the builders outlet store, and they luckily had sizes that fit. It was as simple as removing the old window, silicone caulk, screw in new window, small bit of low expansion foam, and then fussing with the trim to make it look perfect. I spent $125 on the replacement window, which was a vinyl double hung replacement style window. I am now looking for one for the bathroom, which is a small odd size, and having little luck at off the shelf options. I used two custom online calculators for windows and got prices $250-400 for the small windows. This seemed outrageous and there must be a better way.

Does anyone in the Rochester area (NY) have tips on where to source windows?

Thanks,
