Yep. Same guy. He did my friend and neighbors roof, siding, bay and some DH windows. Turns out, the neighbor in question went to work for him as a labor hand - with no experience - a couple days after they started my house and was actually one of the chisel guys. I don't think the neighbor knows what is/isn't under his shingles, but the windows looked OK to me and to him. I should have been more diligent, lots of egg on my face. But I will tell you, where I live, it is very difficult to get any contractor, and none put up with much inquiry. Very busy in this market, even now, and I didn't nickle and dime anyone, had the money to pay for most bids I got. I had to put the door in or face the elements, and paid a reputable contractor/carpenter about $900 total to rebuild the opening to make the door work. It is not what I wanted, but it is ETC eligible and looks and operates better than I would have expected of that grade to work, so I may just keep it. One saving grace: I didn't give him a penny (his offer not to pay till the job was done). He did scrap my aluminum siding, soffit, and windows, but that can't be worth that much. And, this is PA where the law changed drastically in July. The onus is on the contractor, with very specific items that must be in the contract or it is unenforceable. Lets just say his paperwork skills aren't any better than his window measuring skills. So, right now, he is out 20 square of GAF/ELK 30 year archectural shingles and related materials, some tyvek and tape, a couple squares of siding, $4200 worth of windows at his cost, some trim coil, and the several days he and his crew spent here. I can file with the AG's office if I want, and I will. But I will likely just find a reputable contractor to redo all the work and send his windows back to him and call it a day, since I am not out anything but time and aggravation, and I like to think I can put that behind me. If the cost goes over, I'll pursue the difference. Thanks for you concern, Skydawggy. Feels better to know there are good guys out there, somewhere. I will let you know how I make out.

It seems this may not be a common question, so I'll share what I have figured out in case anyone else comes looking on this forum. I finally found a distributor who had a 100 series sliding door in their showroom that I could look at. It is a clear step down in how smooth the glide is from the 400 series. It doesn't roll with the ball bearings, and has the look/feel of an entry level door (which is what Andersen calls it, so I guess that is fair). I have not yet found a 200 series Narrow Line door that I can test out. My local Home Depot has a 400 series door, the one a little farther away has a Perma-shield door, but no narrow line. If anyone wants to chime in and comment on the functionality of a Narrow Line 200 series door, I would appreciate it! Thanks!

A series doors - the frames are fiberglass-clad wood and the door panels are LVL wood coated, and, it would appear from the literature, not fiberglass-clad, but directly finished with Flexacron. The A series windows are Fibrex (composite) frames with a wood-interior and fiberglass sash exteriors with a wood interior. The picture windows are fiberglass for both frame and sash. I would hesitate to call them clad, as it they are not full-dimensional wood wrapped with a form-fitting fiberglass "skin" like aluminum-clad windows are. The exterior fiberglass/fibrex components are quite distinct from the wood structural/aesthetic components and no part of the wood sits outside of the exterior sheathing of the wall. The E-series has more customization - you can specify the stile and rail sizes to get either a more contemporary or traditional appearance. You can have paneling added. There are many more colors available. You can get a flush-sill, venting sidelights and shades between the glass. A series does not offer these things. The A-series definitely has a more "traditional" appearance.

"Sometimes when you are shopping for windows it can feel like all the windows look the same but hopefully, this article helped clear up some of the differences between two of Andersen's product lines. Remember the main differences between these two lines is in the material, the variety of styles, and the lead-time." found at https://brennancorp.com/blog/andersen-100-series-vs-200-series-replacement-windows-review
