Any recommendations for replacement windows? We are in an 1870s-ish home that came with replacement windows. A few of them have failed and fogged up, and I am just generally not a fan of them. Can't figure out what brand they are. Given our neighborhood and budget, I don't want to go super high end. Right now we are just re-doing the kitchen so only buying four, one of which is a picture window over the sink. My contractor recommended Pella ProLine or 250 series but I have heard some mixed reviews.
