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.

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.

I've been dealing with leaking gutter seams for years and tried everything from hardware store caulk guns to tape products. Nothing worked until I invested in this professional Malco caulking gun and proper gutter sealant. The difference in application quality is night and day - I could get the sealant exactly where it needed to go with perfect pressure control.

As a professional gutter installer, I've used many caulking guns over the years, but the Malco Professional model is by far the best.
