Before you begin to install gutters, assemble as much of the gutter system as you can while you are on the ground. Working on the ground minimizes the amount of work you will have to do later while you are standing on a ladder or scaffolding. Assemble a bend to connect the gutter with the downspout, using two offset bends with a length of downspout between them. Adjust the middle section of downspout so that the main downspout will lie against the wall (image 1). Push the bend into the bottom of the running outlet to fit it in place. Then push the downspout into the off-set bend (image 2).
Hold a bracket in place at the top of the downspout and draw through the fastener holes to mark the wall (image 1). Use a masonry bit to drill pilot holes at the marked points. Insert wall plugs into them (image 2). Screw the bracket into position over the downspout (image 3). Secure more brackets every three feet along the length of the downspout (image 4).
Set up a string line for metal gutters just as you do for vinyl. Cast-iron gutters will not have union brackets, but lightweight aluminum involves using a hole cutter to make holes in gutter lengths, allowing running outlets to be positioned as required. Join lengths with a union bracket that creates a watertight seal (image 1). Attach a stop end and clip it into place (image 2). Use a running outlet where the hole has been cut to clip over and around the gutter profile (image 3).
