What Are Gutter Guards?
Gutter guards are protective covers installed over your eavestroughs to block leaves, twigs, and debris while allowing water to flow freely. They’re especially valuable in areas like Niagara, where seasonal storms and falling leaves can quickly clog unprotected gutters. By keeping your system clear, gutter guards help prevent overflow, ice dams, and costly water damage.
Custom-fit Gutter Guard Installation for Long-Term Protection
At Custom Seamless Eavestrough, we specialize in precision gutter guard installations tailored to each home’s unique layout and drainage needs. Our systems are designed for maximum performance and minimal maintenance, helping you protect your investment with confidence.
Custom Fit for Every Home
Our gutter guards are precisely measured and installed to match your existing system, ensuring seamless integration and optimal performance. No gaps, no misalignment, just a clean, secure fit that works.
Stop Clogs Before They Start
Designed to block leaves, twigs, and debris before they enter your gutters, our guards keep water flowing freely, helping you avoid overflow and costly damage.
Low-Maintenance Living
With our guards in place, you’ll spend less time on ladders and more time enjoying your home. They significantly reduce the need for seasonal cleanings and keep your system running smoothly year-round.
Durable, Weather-Resistant Materials
Built from premium-grade aluminum and engineered for Niagara weather, our guards resist rust, warping, and wear.

Our experienced crews work efficiently and respectfully, ensuring a fast turnaround and a spotless job site. We treat your home like it’s our own, with attention to detail at every step.
Compatible with New & Existing Gutters

Alu-Rex Products
Protecting Your Existing Gutter with The Gutter Clean System®
Gutter Clean System® gutter guards are designed to be easier to maintain by letting the wind do most of the heavy lifting. Because their surface is made of perforated aluminum, debris sits on top, dries out, and is carried off by the breeze. Alu‐Rex guarantees your gutters will stay clog‐free for 25 years.
T-Rex® Continuous Hanger – Reinforced Strength for Your Gutters
-
High-strength Aluminum Construction
Crafted from 3105 H24-grade aluminum with a robust 0.0175" thickness, this hanger delivers exceptional structural integrity and long-term reliability in any environment.
-
Self-sealing Fasteners
Each hanger is installed using black Dracotized steel screws with integrated rubber gaskets. These 1½" screws feature ¼" hex heads and are designed to seal tightly, helping prevent water intrusion into the fascia while securing the system firmly in place.
-
Continuous Support, No Weak Points
Unlike traditional hangers spaced intermittently, the T-Rex® system provides uniform reinforcement along the entire gutter length, supporting up to 250 lb (113kg) per linear foot. That means better performance in heavy snow, ice, and storm conditions.
Cutting Edge Technology with DoublePro®
-
Eclipse™ Technology
The double membrane keeps debris from getting inside the gutter. The offset holes make it the perfect filter, allowing water to drain freely while blocking pine needles and leaves without ever getting clogged.
-
Vortex™ Technology
The suction created by the two membranes makes it possible to drain three times more water than ever recorded in the heaviest storms. The inner membrane draws water through the wider holes.
-
Roll Back™ Technology
Designed for high-volume drainage, this feature redirects excess rainwater back into the gutter, preventing spillover. Independent testing confirms its ability to handle extreme rainfall without overflow.
-
Unmatched Structural Strength
The DoublePro® Continuous Hanger™ reinforces your gutter system from end to end, eliminating weak spots and ensuring consistent support. With the ability to withstand up to 425 lb (193 kg) per linear foot, it’s built for long-term durability, even under heavy snow and ice.
