katie, that is a VERY open-ended question. The price you can expect to pay can very significantly based on size, option content, installation circumstances, business model of the installation company, etc. We would need significantly more info to comment more specifically on what is or is not a fair price. What I can say, is that for a very broad range of pricing on a good product from a reputable company, you could be in the $400's on the very low end, up to knocking on the door of $1000 if you have a Cadillac option package and complex install. The most highly regarded vinyl lines frequently mentioned are HiMark, Sunrise, Softlite, Okna, Polaris. They all have a "good, better, best" product lineup as well.

OK, I have a quotation. This is for Soft-Lite Imperial LS, double pane, low E argon, with superspacer. (I incorrectly thought they were Elements in a previous post.) 2 @ Window opening 48" X 40"; 2 casements per opening, so 4 windows total. 1 @ Window opening 97" X 52" picture window + 1 casement on either side (so 3 windows total) 1 @ Window opening 68" X 45" picture window + awning (tempered glass in awning) 2 @ window opening 68" X 45" picture window + awning (tempered glass in awning) These 2 windows are side-by-side (so 4 windows total). Full frame replacement, white exterior, woodgrain interior. Also interior wood trim stained to match and installed. Total came to $11,100. Seems a bit rich to me.

vic, if you are unable to locate one of the brands that are universally well regarded by pros, my best recommendation would be to take a close look at performance ratings. You can look at window performance the same way you look at mileage and horsepower when buying a car. U factor and air leakage are two big ones... There is a little complexity when it comes SHGC and others as the optimum numbers can vary based on climate, but the these ratings are a great guide either way.

This was done by lowes they used simple red house wrap tape to seal the nailing fins and then went over it with the 4 inch cedar. When I found the 50 foot roll of Pella Smart Smart Flash they did not use I had a bird. I told em they would have to take all the trim boards off to replace the red cellophane like tape. So the 12" siding is cut flush with the removed 4 inches of tar paper. Your saying they should put down a vapor barrier to the edge of the tar paper, wrap around the opening and lay the windows down(so pull out the windows also?) Then nail the fins down over sheathing and then go over with the Smart tape like they should of? How do you get vapor barrier to abut to to the tar paper or peal the siding back to get under tar paper and tape down? The jobs been a nightmare from Lowes its a week of downpour rain my windows are waiting to be caulked and I told em the job had to be done right. They asked to use my ladders had no caulk, had to reorder the interior trim boards and jobs now a week old windows are half but put in. Thanks What WRB?
