About Custom Seamless Eavestrough
At Custom Seamless Eavestrough, we’re more than just a contractor, we’re your neighbours, your partners, and your go-to experts for high-quality aluminum work in St. Catharines and the surrounding Niagara region. With over 35 years of experience, we’ve built our reputation on honesty, craftsmanship, and a deep commitment to protecting the homes and properties in our community.
What began as a small, family-run business has grown into one of the most trusted names in exterior finishing. But while our tools and techniques have evolved, our values haven’t changed. We still believe in showing up on time, doing the job right, and treating every home like it’s our own. Our clients aren’t just customers, they’re part of the community we’ve helped build, one project at a time.
Our Mission:
Seamless Service, Lasting Results
We specialize in eavestrough systems, designed and fabricated on-site to ensure a perfect fit for every home. Our work goes beyond standard installations, we offer precision downspout configurations, gutter guard integration, custom aluminum infills, and professional finishing that elevate both function and curb appeal.
We also provide a full range of complementary services, including soffit and fascia installation, vinyl and aluminum siding, gutter cleaning, and shed construction and repair. Whether you’re a homeowner looking to protect your investment or a contractor managing a new build or retrofit, we bring the same level of care, attention to detail, and pride in our work.
