FIXING COMMON GUTTER LEAK PROBLEMS
IDENTIFY & FIX LEAKING GUTTERS LIKE A PRO
Leaking gutters can cause significant damage to your home if left unrepaired. Understanding the common causes and solutions will help you make effective, long-lasting repairs:
LEAKING GUTTER SEAMS
Problem: The most common source of gutter leaks occurs at the seams where gutter sections join together. Over time, the original sealant deteriorates due to weather exposure and thermal expansion/contraction.
Solution: Using the Malco Professional Caulking Gun, apply a high-quality gutter sealant like Ruscoe Permanent Sealer directly into the seam. The precision tip allows you to force sealant deep into the joint for a complete seal. For best results:
- Clean and dry the seam thoroughly
- Apply sealant to both inside and outside of the seam
- Use the smooth pressure control to create an even bead
- Allow 24-48 hours to cure completely
LEAKING GUTTER CORNERS
Problem: Corner joints are particularly vulnerable to leaking because they experience more movement and stress than straight seams. Water often pools at corners, increasing the likelihood of leaks.
Solution: The Malco Professional Caulking Gun's precision tip is perfect for accessing tight corner joints. For effective corner repairs:
- Remove all old sealant and debris from the corner
- Use the puncture wire to clear any clogs in your sealant tube
- Apply a generous amount of sealant to fully fill the corner joint
- Smooth with a plastic tool for a professional finish
- For severely damaged corners, consider installing a new corner piece before sealing
LEAKING DOWNSPOUT CONNECTIONS
Problem: The connection between gutters and downspouts often leaks due to improper sealing, loose fittings, or damage from debris.
Solution: The ergonomic design of the Malco Professional Caulking Gun makes it easy to work at awkward angles around downspout connections:
- Ensure downspout is properly attached to the gutter outlet
- Apply sealant around the entire connection point
- Use the controlled pressure feature to prevent excess sealant that could block water flow
- For persistent leaks, consider replacing the downspout connector
LEAKING GUTTER END CAPS
Problem: End caps frequently leak due to poor initial installation, impact damage, or sealant failure.
Solution: The precision tip of the Malco Professional Caulking Gun allows for accurate sealant application around end caps:
- Remove the end cap if possible and clean thoroughly
- Apply a continuous bead of sealant around the entire perimeter
- Reattach the end cap and wipe away excess sealant
- For damaged end caps, replace with new ones before sealing
- Apply additional sealant to the outside edges for extra protection

HOW TO FIX LEAKING GUTTERS: STEP-BY-STEP GUIDE
PROFESSIONAL GUTTER REPAIR PROCESS
IDENTIFY THE LEAK SOURCE
During a rainstorm, observe where water is leaking from your gutters. Common leak points include seams, corners, end caps, and downspout connections. Mark these areas for repair. If it's not raining, run water through your gutters with a hose to identify leaks.
CLEAN THE REPAIR AREA
Thoroughly clean the leaking area, removing all debris, dirt, and old sealant. Use a wire brush for stubborn residue. For best results, clean both the inside and outside of the gutter at the leak point. Allow the area to dry completely before proceeding.
PREPARE YOUR CAULKING GUN
Load the Malco Professional Caulking Gun with Ruscoe Permanent Sealer or similar high-quality gutter sealant. Cut the tip of the sealant tube at a 45-degree angle, making the opening appropriate for your repair (smaller for fine seams, larger for bigger gaps). Use the built-in puncture wire to pierce the inner seal of the tube.
APPLY SEALANT PRECISELY
Using the Malco Professional Caulking Gun's precision tip and controlled pressure feature, apply a continuous bead of sealant directly into the leaking seam, joint, or corner. The ergonomic grip allows you to maintain steady pressure for an even application. For seams, apply sealant to both the inside and outside of the gutter for maximum protection.
SMOOTH AND FINISH
After applying the sealant, use a plastic smoothing tool or a gloved finger to press the sealant firmly into the seam and create a smooth, finished appearance. This ensures complete coverage and improves the waterproof seal. Wipe away any excess sealant with a cloth.
ALLOW TO CURE
Allow the sealant to cure completely according to the manufacturer's instructions, typically 24-48 hours. Avoid exposing the repair to water during this time. After curing, test the repair by running water through the gutter to ensure the leak has been successfully sealed.
PROFESSIONAL MAINTENANCE TIP:
For long-lasting gutter performance, inspect and reseal gutter joints every 2-3 years. Keep your Malco Professional Caulking Gun clean and ready for use by releasing pressure and wiping the tip after each use. Store partially used sealant tubes with a nail or screw in the tip to prevent drying out.
FREQUENTLY ASKED QUESTIONS
How do I fix leaking gutters?
To fix leaking gutters, first identify the source of the leak (usually at seams, joints, or corners). Clean the area thoroughly and allow it to dry completely. Using a professional caulking gun like the Malco Heavy Duty model, apply a high-quality gutter sealant like Ruscoe Permanent Sealer along the leaking seams or joints. The precision tip and controlled pressure of a professional caulking gun ensures the sealant penetrates deeply into the joint while creating a smooth, waterproof seal. For larger gaps, you may need to apply aluminum gutter patch material before sealing. Regular maintenance and resealing every 3-5 years will prevent future leaks.
What causes gutters to leak at the seams?
Gutters leak at the seams primarily due to: 1) Thermal expansion and contraction that gradually weakens the original sealant; 2) Water freezing in the seams during winter, causing separation; 3) Improper initial installation with insufficient sealant; 4) Age-related deterioration of sealant materials; 5) Debris buildup causing water to pool at seams. Using a professional-grade caulking gun with the right sealant allows for precise application into these seams, creating a watertight bond that accommodates the natural movement of gutters while preventing water penetration. Regular cleaning and maintenance can help prevent seam leaks from developing.
What is the best sealant for leaking gutters?
The best sealant for leaking gutters is a professional-grade, 100% waterproof product specifically designed for exterior metal applications, such as Ruscoe Permanent Sealer. Look for sealants that are: 1) Silicone or tripolymer based for maximum flexibility; 2) UV-resistant to prevent breakdown from sun exposure; 3) Able to adhere to wet surfaces for emergency repairs; 4) Rated for extreme temperature ranges (-40°F to 200°F); 5) Paintable to match gutter color. For optimal results, apply with a professional caulking gun like the Malco Heavy Duty model, which provides the precise control needed for clean, effective application into narrow gutter seams.
How do I stop my gutters from leaking at the corners?
To stop gutters from leaking at corners: 1) Clean the corner thoroughly, removing all old sealant and debris; 2) Ensure the area is completely dry; 3) Using a professional caulking gun like the Malco Heavy Duty model, apply a generous bead of high-quality gutter sealant along the inside of the corner joint; 4) Use the precision tip of the caulking gun to work the sealant deeply into the joint; 5) Smooth the sealant with a plastic tool for a professional finish; 6) Allow to cure completely (usually 24-48 hours) before exposing to water. For severely damaged corners, consider installing aluminum corner pieces before sealing for added reinforcement.
Why is my gutter leaking at the downspout?
Gutters leak at downspouts due to: 1) Loose connections between the gutter and downspout; 2) Deteriorated sealant at the connection point; 3) Improper initial installation; 4) Damage from impact or debris; 5) Corrosion at the connection point. To fix this common problem, first ensure the downspout is properly attached to the gutter outlet. Then, using a professional caulking gun like the Malco Heavy Duty model, apply waterproof sealant around the connection point. The precision control offered by a professional caulking gun allows you to direct sealant exactly where needed, creating a watertight seal that prevents leaks while allowing water to flow freely through the downspout.
