Okna 600 vs 500
Good afternoon, I read your review about Okna, very good reviews, thanks! Also, I got a quote from AWS in Connecticut. So, they gave a quote of $24000 to replace 4 twins, 2 triple, 4 singles with Okna 600 triple panes. Does this price seem reasonable? I wonder if the Okna 500 series will be much lower.
Can you please recommend reputable window replacements companies in the Middlesex Connecticut area who carry Okna 500 or 600 series? Lastly, thanks for your help!

[Site Editor’s Answer]
O. H., I don’t know of reputable window companies in your state per se. I can certainly send you my list of window brands in general and we can hope there are a few of them available.
Anything over $1K per window for me means you’re going to want more bids to see if the bid is actually fair based on your project requirements or whether the bid is too expensive. Specifically, the Okna 500 series should run 20% less than the 600 series, but dealer pricing is tough to predict because it is often based on the deals that they get from the manufacturer and that varies by volume, location, etc….

Okna 500 Deluxe Double Hung Cost
Hi Steve, I was quoted today on 26 Okna 5500 Deluxe Double Hung new construction windows and 3 half rounds new construction), triple pane with built in grids colonial style. For the windows and installation the cost came to $27,640. With the energy star rebates I will be saving approx $3500 so technically $24k. This price also includes the indoor trim and extension jambs. These are pretty big windows, 28×62. Do you think this is a fair price or is it high? I live in CT if that helps.
Mike – Homeowner – from 2023
[Site Editor’s Answer]
Mike, that sounds like a very fair price to me given the indoor trim and extension jambs portion of the job. Well done — I’m seeing much higher prices in general elsewhere in the country. Just make sure the installer is worth his salt 🙂
