  2. Dry it completely.
  3. Apply silicone caulk generously.
  4. Let it cure for 24 hours.

Materials and Estimated Cost

2. Replacing Rusted Screws and Fasteners

Why Rusted Hardware Causes Bigger Issues

Rusted fasteners don’t just look bad—they weaken your entire downspout structure. Eventually, it’ll sag or fall off.

What to Use Instead

Replace them with stainless steel or galvanized screws. They’re rust-resistant and built to last. This one change can save you future headaches and support long-term drainage protection.


3. Patching Small Holes with Aluminum Tape

A Temporary Yet Effective Fix

Got a tiny puncture or corrosion spot? Don’t toss the whole downspout. Aluminum tape is waterproof and weatherproof. Clean the area, slap the tape over it, and boom—you’ve got a patch that lasts through the season.

Bonus: It costs under $10 for a whole roll.
