I was just quoted around $2200 to install side curtains and rear curtain to an existing top with the zippers already installed. The top is a year old and the previous owner had the zippers installed to anticipate side/rear panels later. It's a 20' wood cruiser and the top has the bimini and rear section. The total length of the top is maybe ten feet, but more like 8. Am I missing something here? I think I could make curtains myself and have them turn out reasonably good. Should I get another estimate or does this sound like the going rate? Oh, and it would take 2 moths before they can do it...
