$5000 sounds in the ballpark. I may end up paying something for installation, depending on if my husband and I do the work (we both worked in construction and he is an excellent carpenter) or if he decides to pay his cousin's company to do it. They also do excellent work. Husband doesn't like to do certain types of construction (as he points out, his cousin will do it better, faster) so it's his decision.
Another pro tip: Based on reviews I got it delivered (hasn't come yet) because it sounds like they are enormous when packaged and the stress of a poor delivery process might harm the doors or glass.
We have solid wood French doors from different companies (like Andersen) that we've installed elsewhere in the house and they have all survived quite well. This one, between the exposure, the possibly poor material it's made from, a dog who decided to start gnawing at it, a generally destructive family (children) and the fact that it's sliding, has not.
I also went looking on Craigslist and in local recycled building materials stores for used replacements (did get 2 great windows once that way), but no luck.
I read the book "Make Your House Do the Housework" and that was when I realized that having extra lights in the doors (as all our replacement double-pane French doors have) was just extra work to clean. Also he recommends reducing the number of doors in and out of your house. In a way I'll miss having this door stuck closed because as a result kids & dogs have not been tramping through my office!
I saw some reviews here on MMM saying the Renewal by Andersen window replacement was a terrible service FYI...
