What's the edging material that frames the siding facade? Nice and clean...

The siding of the house almost makes the picture almost look photoshopped! I don't think I've ever seen a more efficient siding job. My husband and I are looking to get new siding installed on our house this summer, and I really think this color would look good on our house. The dark grey would compliment the other accents of our home. Hopefully we can get it taken care of soon! http://www.sidingalabama.com/services
