Ever walked into your basement after a storm and found puddles where your carpet used to be dry? Yeah, weโve all been there. The culprit? Often, itโs your downspouts not doing their job. In this article, we’re diving into 7 smart downspout repair tips to prevent basement leaksโbecause a dry basement is a happy basement.
Letโs break it down and keep that rainwater where it belongsโoutside your home.
Why Downspout Repairs Matter
The Hidden Danger of Water Damage
Water might look harmless, but when it sneaks into your basement, it can quietly destroy your walls, flooring, and even the foundation. A faulty or clogged downspout doesnโt just cause leaksโit invites mold, mildew, and massive repair bills.

How Leaky Downspouts Cause Basement Flooding
Hereโs the short version: Rain hits your roof, flows through the gutters, and should exit through your downspouts away from your house. If your downspouts are cracked, clogged, or too short, water pools around your foundationโand gravity does the rest.
Tip #1: Regular Gutter and Downspout Cleaning
Preventing Debris Clogs
Leaves, twigs, bird nestsโyour downspouts catch more than rain. Clogs are the number one cause of overflow and basement seepage. Cleaning your system twice a year (spring and fall) is essential.

Tip #2: Check for Visible Damage
Cracks, Rust, and Loose Joints
Even minor cracks or rusty seams can lead to huge leaks. Run your hand along the downspout after a storm. If you feel dampness or see stains, itโs time for action.
What to Do if You Spot a Problem
Small cracks? Use waterproof sealant. Rusted areas? Sand them down and coat with weatherproof paint. If itโs more serious, consider calling a licensed contractor for assessment.
Tip #3: Ensure Proper Downspout Extension
Water Should Drain Away From Your Home
If your downspout ends right at your foundation, youโre inviting trouble. A good rule of thumb: direct water at least 4-6 feet away from your house.
DIY Extension Options
- Flexible plastic tubing
- Rigid downspout extenders
- Buried drainpipes for hidden drainage

Tip #4: Seal Leaky Joints with Waterproof Tape or Sealant
Temporary Fixes That Work
Sometimes, the fastest fix is the most effective. Waterproof duct tape or rubber sealant works wonders on seams that weep during storms.
When to Call in the Pros
If leaks persist after sealing, you may have internal corrosion or blockages. Thatโs when you need professional help.
Tip #5: Use Splash Blocks or Drainage Pipes
Directing Water Flow Properly
A splash block or drainpipe at the base of your downspout keeps water flowing away instead of pooling by your basement wall. Simple, cheap, effective.

Tip #6: Secure Loose Downspouts
Fasteners, Brackets, and Straps
Loose downspouts sway in the wind, disconnect from elbows, and can collapse mid-storm. Use metal brackets or vinyl straps to secure them tightly to your siding.
Avoiding Wind Damage and Vibrations
Noticed rattling in the wind? Thatโs a red flag. Tighten now to avoid more costly downspout problems later.
Tip #7: Schedule Annual Downspout Inspections
What a Pro Will Look For
Professionals check for:
- Internal clogs
- Joint integrity
- Slope alignment
- Corrosion and wear
This is especially important if your home has experienced leaks before.

At least twice a yearโonce in spring and once in fall. If you have many trees nearby, check more frequently.
2. Whatโs the best way to fix a leaking downspout joint?
Use waterproof sealant or aluminum tape as a temporary fix. For long-term results, replace the joint or call a pro.

Yes, especially if youโve had leaks before or suspect hidden damage. Professionals catch issues you might miss.

Use a flexible extension or splash block. Both are budget-friendly and easy to install.
