I've received two quotes that ended up being identical in price at $870. One quote was actually about $960 but they included a 10% Angies List discount. Both quotes are from the two 2 rated companies on Angie's List

Here's the details:

- 1 story house
- 180 linear feet of 6" aluminum seamless gutters in white, formed on site
- 6 3"x4" downspouts (elbows and straight runs are separate pieces)
- Hidden hangers
- All corner joints and end caps are caulked
- Galvanized screws w/neoprene washers and ceramic washers to secure down spouts and elbows
- 5 years warranty labor
- 20 year warranty on material

The company I am looking to go with specified that they will install the gutters correctly with then being up under the drip edges, and even pointed out how the gutters on my neighbors house are mounted to low and their fascia is probably rotting away (all the houses on the street have 1x6 wooden fascia)

Does this all look good from a spec standpoint? I see mixed opinions on screws vs. rivets online. These guys said they used to use rivets but switched to screws years ago. Everything else they specified seems to jive with what is generally recommended online.
