Most people never think about sheet metal.
It’s hidden behind walls, above ceilings, and inside mechanical rooms, quietly doing its job every day.
But at Thornton Heating & Sheetmetal, some of our favorite projects are the ones you actually get to see.
For more than 50 years, we’ve been fabricating custom sheet metal that goes far beyond HVAC ductwork. From stunning copper range hoods and handcrafted backsplashes to architectural accents, countertops, and decorative metal finishes, we create one-of-a-kind pieces that become the focal point of your home.
Beautiful craftsmanship. Exceptional function. Built right here in the Wood River Valley.
While our custom sheet metal shop produces precision ductwork for homes and businesses throughout Southern Idaho, we also specialize in architectural metalwork that blends craftsmanship with everyday functionality.
Our custom fabrication services include:
Every project is custom designed, built, and finished specifically for your home.
A handcrafted range hood can completely transform a kitchen.
Whether your home is mountain modern, contemporary, rustic, farmhouse, or traditional, a custom range hood creates a striking focal point while providing exceptional ventilation performance.
Choose from premium materials including:
Each hood is fabricated to your exact dimensions, ensuring a seamless fit that complements your cabinetry, countertops, and overall design.
No stock sizes.
No compromises.
Just beautiful craftsmanship built specifically for your space.
Copper continues to be one of the most requested materials for custom metalwork—and for good reason.

Every custom project begins with a flat sheet of metal.
From there, our experienced craftsmen carefully measure, cut, bend, weld, and finish each piece by hand in our Ketchum sheet metal shop.
Because we fabricate everything ourselves, we maintain complete control over quality from the first measurement to the final installation.
The result is custom metalwork that’s built to last—and built to impress.
No two homes in the Wood River Valley are exactly alike.
That’s why we don’t believe in one-size-fits-all fabrication.
Whether you’re building a luxury mountain home, remodeling your kitchen, updating a fireplace, or adding architectural details, every project is designed around your home’s unique style and your personal vision.
