I have a 15-year-old house that was only partially surrounded by seamless guttering (per the builder's allowances). I always intended to finish it off, but never have.

We're setting out on a few home improvement projects this year, and that's on the list. Just want to amend the existing guttering to cover the entire perimeter of the house - I'm guessing only about 70 feet +/- plus appropriate downspouts. Looking for recommendations and guesstimates of reasonable cost per linear foot....thanks.
