Step 1 - Remove Upper Elbow

Using a drill, drill the rivet heads around the upper elbow to loosen it. Pull the elbow out.

Step 2 - Remove existing Downspout

Drill the rivet heads around the metal brackets (strips) that hold the downspout. When the metal brackets are loose, remove the screws on the metal brackets. Metal brackets are fixed to the wall and downspout and help to keep the downspout in place.

Step 3 - Remove Lower Elbow

Take a drill and drill out the rivets around the lower elbow to loosen it. Pull out the lower elbow.

Step 4 - Make a Hole

For the connector opening, use a drill with a hole saw attachment and drill into the gutter at the bottom. Make sure that it is done correctly and accurately. Using a pencil draw a line on the underside around the connector. Use sheet metal strips to cut it in a rectangle shape.

Step 5 - Fasten the Connector

Secure the connecter with metal screws by fitting it into the hole from the top. Make sure it is fastened properly.

Step 6 - Leak Proof the Connector

To prevent future leaks, apply caulk around the connector. Be careful and make sure the connector is dry for maximum effect before applying the caulk. You can use a heat gun around the area to make sure it dried up properly.

Step 7 - Slide an Elbow

Secure the elbow using a screw, which is made from sheet metal after sliding it into the connector. Make sure that it is secured properly and tightly.

Step 8 - Measure Length for 2 Elbows

Fasten and secure the second elbow to the wall of the house. Take the accurate measurement between both the elbows so that you will be able to know what the length is to connect them. On the basis of the measurement, cut the required length using the circular saw using the measurement of the downspout. Make sure you wear safety gloves and goggles to protect yourself.

Step 9 - Take the Measurement of the Downspout and Cut Accordingly

Once you fit the length of the first cut into the elbow you need to take the tape and measure the elbow, which is fastened into the ground. Make sure that it measures at least 8 inches off the ground. Based on the measurement of the length, take another piece of the downspout, cut it according to the measurement of the length, and fasten it using the screw that is made from sheet metal.

Step 10 - Fasten and Secure the Downspout with Hex Head Screws

Using straps made out of aluminum secure the downspout and fasten it properly with the required number of hex head screws.
