Some additional details could have an effect on how good the deal is, but it is definitely not price gouging or anything like that. Little bit higher than what I usually see, but not completely out of the range of reason by any means, especially if it is the only product being installed.

Tough to say without a price in the original post.

That is a pretty solid door though.

How does the company look via work samples and reputation?

Quote was $3100. Work samples looked good. recommended by friend.

with that option content I would say that the price is within the range of reason

+1

Very much inside the range of normal.

price is good for that door. Very solid choice.

Any recommendations for 60" patio doors
I am looking for a reliable quality in the mid-price range.
I live in Northern Chicago Subs, so either Chicagoland or Milwaukee supplied will work.
One installer recommended Alside, but I have heard not good things about them.
I would greatly appreciate thoughts.

Here is a link that might be useful: member page

60" Sliding door or Hinged Patio/French.

In either case, HomeSealed (regular poster on here) is out of Milwaukee.

He carries all the best lines and is a top notch company.
