Is the price for the French balcony okay or should I obtain more offers?

Hello,

I have an offer for 2 French balconies of:

one 1 m and one double (2 m)

for a total of 852 € including installation, galvanized.

Is that okay or should I get more offers?
Does anyone have prices for this?

Of course, it always depends on what exactly is to be delivered. "1x French balcony to take away" is quite flexible. But in the calculation of a general contractor, we were also charged €300 per window, which roughly aligns with yours.

What kind of design, material

I rather think it's a simple version and galvanized is written there. There is one double and one small.
