I used 6 1/4 cedar-tone lap siding to side my house myself 12 years ago. I ordered it from Home Depot and got a 20% discount if I ordered an entire pallet. I ordered the primed siding and, following the Hardie instructions to the letter, took two summers here in Minnesota to install and paint. Standard siding is 16′ but the Hardie board come in 12 ‘ lengths because of weight. I lapped it to 4″ because that fit the style of our1893 home. The delivery truck deposited the pallet in my driveway, free delivery, and I carefully carried on edge the siding into the garage to protect from the elements. I made 2 hangers so that I could hook them over the top of a finished lap and it would remain in place at the 4 ” level. Until I found a Hitachi blade specially made for Hardie board I went thru a lot of blades. If you have the time and follow the instructions, you should be able to do it yourself although it seems the warranty doesn’t cover self installation. To coats of good paint over the primer and it still looks like new. I predrilled all holes before nailing.
