When most people think about gutters, they think about function. Gutters move rainwater away from your home, protect your foundation, and help prevent water damage. They’re essential—but they don’t have to be ordinary.
At Thornton Heating & Sheetmetal, we believe even the most practical parts of your home can become works of craftsmanship.
Our custom copper gutters are built by hand in our Ketchum sheet metal shop, combining timeless beauty with exceptional durability. They’re designed to protect your home today while becoming even more beautiful with age.
Copper has been trusted in architecture for centuries because it performs as beautifully as it looks.
Unlike traditional aluminum or vinyl gutters that may fade, dent, or require replacement over time, copper develops a rich natural patina that enhances its appearance year after year. The warm bronze finish gradually transforms into deep browns and subtle green hues, creating a one-of-a-kind look that reflects the character of your home.
Every season leaves its mark, making your gutters a living architectural feature rather than something hidden from view.
At Thornton Heating & Sheetmetal, every copper gutter system is custom fabricated in-house by skilled craftsmen who have been serving Southern Idaho since 1973.
Because we build each system ourselves, we’re able to create gutters that fit your home perfectly—not rely on mass-produced components that require compromises during installation.
Our custom fabrication includes:
Whether you’re building a new custom home or updating an existing residence, our team works closely with homeowners, architects, and builders to create a finished product that complements your home’s design.
Homes throughout Ketchum, Sun Valley, Hailey, Bellevue, Stanley, and the surrounding mountain communities experience heavy snow, ice, spring runoff, and seasonal weather extremes.
Copper is one of the most durable materials available for these conditions. It naturally resists corrosion, stands up to harsh weather, and requires very little maintenance over its lifetime.
Instead of replacing your gutters every couple of decades, copper often lasts for generations.
Luxury homes are defined by thoughtful details.
Custom copper gutters provide clean architectural lines while adding warmth, texture, and character that simply can’t be replicated with painted aluminum systems.
Whether paired with natural stone, cedar siding, timber framing, or modern mountain architecture, copper creates an elegant finish that continues to improve with time.
It’s one of those rare building materials where function truly becomes beautiful.
