Steel downspout installation can help reduce the buildup in your gutters and create a flow for the water to properly drain away from your home. Your gutters catch precipitation before it flows down and off your roof and downspouts allow the water collected in your gutters to drain out and away from your home.

Step1 – Planning

The first thing you need to do is plan where to place the downspouts. Check your gutters after a rain to determine where the water naturally flows. You should also determine the best location for the excess water to drain. Downspouts should not be in a high traffic area or in a location where excess water drainage may damage plants or landscaping.

Step 2 – Install the Gutter Sleeve\Saver

The first step in the actual installation is to install a sleeve or saver into your existing gutter in the location of the desired downspout. A sleeve or saver, called by either name depending on the manufacturer, is a small square piece that fits into the existing gutter. The sleeve holds and connects the downspout to the gutter system. First, hold the sleeve up to the gutter where you want your downspout installed and trace an outline of the sleeve onto the gutter using a permanent marker. Next, you will need to use the metal sheers or scissors to cut along the tracing creating a gap in the gutter where the sleeve will rest. Now you are ready to install the sleeve. Apply a ribbon of sealant along the outer rim of the sleeve and insert the sleeve into the notch you cut in the gutter. Once the sleeve is in place, secure it using a metal screw on each top corner of the sleeve where it meets the gutter. Allow the sealant adequate time to set before proceeding to the next step.

Step 3 – Attach an Elbow System

Once the sleeve sealant has set, you are ready to install an elbow system extending from the sleeve. The elbow system will create a connection for the downspout and align the downspout with your house. The first step in creating the elbow system is to place an elbow into the sleeve. The elbow’s angle should point it away from the gutter and toward the house. Attach the first elbow to the sleeve with a screw on each side. Now install an elbow extension fitting into the first elbow and align it perpendicular to the house. Now you are ready to install the second elbow by attaching it to the bottom of the elbow extension. The second elbow should be as flush to the house as possible.

Step 4 – Install the Downspout

You need to measure the downspout to see if it is the proper length. Your downspout should extend from the second elbow to about 6 inches above the ground. If your downspout is too long, you need to make a cut to the top of the downspout using your hacksaw. Once the downspout is the desired length, insert it into the second elbow. Next, you need to install an elbow at the bottom of the downspout to carry the water to the ground.

Step 5 – Secure the Downspout

After installing the downspout, you need to secure it to your house. Wrap a metal strap around the downspout just below where the second elbow and downspout are connected. Using the proper screws, screw each side of the metal strap to your house. The type of screw that you need for this depends on the type of material used to construct your home. Repeat this step to install several metal straps down the downspout to where the downspout meets the bottom elbow. The placement of your metal straps can vary between 5 feet and 8 feet apart, but should be no more than 10 feet apart.

Once the installation is complete, you can check the downspout for leaks by using a water hose and flushing water into the gutter just beside the downspout. If you discover any leaks, you can patch them by applying a small amount of plastic cement. Apply the cement in a very thin layer and allow to fully dry before testing again for leaks.
