How to Install Gutter Downspout - Comprehensive Guide for Homeowners (1)

Effective gutters are crucial for protecting your home from water damage, but they’re only half the equation. A well-designed downspout system channels rainwater away from your foundation, preventing erosion, leaks, and basement flooding. If you’re handy and looking to save some money, here’s a detailed guide on installing a gutter downspout yourself:

Tools and Materials:

  • Ladder
  • Safety glasses and gloves
  • Tape measure
  • Level
  • Pencil or marker
  • Aviation snips or hacksaw
  • Tin snips (for metal downspouts)
  • Drill with various drill bits (including a masonry bit for brick or concrete)
  • Rivet gun and rivets (for metal downspouts)
  • Screwdriver
  • Silicone sealant
  • Downspout elbow (90-degree or adjustable)
  • Downspout straps (choose a style that complements your siding)
  • Downspout extensions (if needed)
  • Splash block or downspout extension with diverter (to direct water away from the foundation)

Choosing the Right Downspout:

Downspouts come in various materials like aluminum, vinyl, and corrugated steel. Here’s a quick breakdown to help you choose:

  • Aluminum: Lightweight, rust-resistant, and easy to cut and install. A popular and affordable choice.
  • Vinyl: Lightweight, comes in various colors to match your gutters, and requires minimal maintenance.
  • Corrugated Steel: Very durable, ideal for areas with heavy rainfall, but can be heavier and noisier during rain.

Sizing: The size of your downspout should be proportionate to your roof size and gutter capacity. Generally, a 2″ x 3″ downspout is sufficient for most homes, but you might need a larger size for bigger roofs or areas with heavy rainfall.

Steps to Installing a Gutter Downspout:

Installing a Gutter Downspout

  1. Measure and Mark: Locate the gutter outlet and measure the distance from the outlet flap to the wall. Subtract about four ¾ inches from this measurement to account for the elbow connection. Mark this point on the wall with a pencil.
  2. Attach the Elbow: At the gutter outlet, apply silicone sealant around the edge of the outlet. Insert the elbow into the outlet, ensuring a snug fit. Secure the elbow with rivets (for metal) or screws (for vinyl/aluminum) on each side.
  3. Cut Downspout Lengths: Measure the distance from the elbow attachment point on the wall down to the desired discharge location (ideally, at least 4-6 inches away from the foundation). Cut the downspout to size using aviation snips or a hacksaw. For metal downspouts, use tin snips to create a clean, angled cut at the bottom if needed.
  4. Attach Downspout Straps: Downspout straps hold the downspout securely against the wall. Position the first strap about 12 inches below the elbow and secure it to the wall using appropriate screws or anchors (depending on your siding material)—space straps evenly down the length of the downspout, typically every 3 feet.
  5. Connect Downspout Sections: Slide the cut downspout section into the elbow. Secure the connection with rivets (for metal) or screws (for vinyl/aluminum) on three sides. Repeat this process for any additional downspout sections you might need.
  6. Attach the Discharge Point: At the bottom of the downspout, attach a 90-degree elbow to direct water away from the foundation. You can then connect a splash block or an extension with a diverter to further extend the discharge point.
  7. Seal the Connections: Apply a bead of silicone sealant around any seams or connections to prevent leaks.

Additional Tips:

  • Maintain a Slight Downward Angle: When attaching downspout sections, ensure a slight downward angle (around 10 degrees) to encourage proper water flow.
  • Use Correct Fasteners: Choose screws or anchors appropriate for your wall material (e.g., wood screws for wood siding, masonry screws for brick).
  • Consider Underground Drainage: If you want to direct water further away from your foundation, consider installing an underground drainage system that connects to the downspout discharge point.

Safety Precautions:

  • Always work on a sturdy and secure ladder.
  • Wear safety glasses and gloves to protect yourself from cuts and debris.
  • Be mindful of overhead power lines when working on a ladder.
