When you see a beautifully crafted copper range hood, a perfectly fitted chimney cap, or custom architectural metalwork on a home, it’s easy to admire the finished product. What you don’t always see is the craftsmanship behind it.

At Thornton Heating & Sheetmetal, every custom piece begins the same way—with a flat sheet of metal and the skilled hands of our experienced fabricators.

For more than 50 years, we’ve been designing, cutting, bending, welding, and finishing custom sheet metal products right here in the Wood River Valley. It’s craftsmanship that’s built by hand—not pulled from a warehouse shelf.

Built In-House. Built to Fit.

Every home is different. Every project has its own architectural style, dimensions, and design goals.

That’s why we fabricate our custom metalwork in our own shop instead of relying on mass-produced products.

Our in-house fabrication allows us to create custom pieces that fit perfectly while maintaining the highest standards of quality and craftsmanship.

We build:

• Custom copper and steel range hoods
• Kitchen countertops
• Architectural sheet metal
• Chimney caps
• Fireplace surrounds
• Decorative wall panels
• Flashing
• Dryer vent systems
• Custom ductwork
• Specialty metal fabrication

Every project is measured, fabricated, and finished specifically for your home or commercial building.

From Flat Sheet to Finished Masterpiece

There’s something satisfying about watching raw materials become something functional and beautiful.

Inside our fabrication shop, flat sheets of steel, stainless steel, galvanized metal, and copper are carefully transformed using specialized equipment and decades of experience.

Our craftsmen cut, shape, brake, weld, and finish each piece with precision, paying attention to every bend, seam, and detail.

The result isn’t simply a metal product—it’s a custom piece built to complement your home’s architecture while standing the test of time.

Copper That Gets Better With Age

One of our favorite materials to work with is copper.

Its rich natural color brings warmth and character to any home, and unlike many building materials, copper continues to evolve over time. As it ages, it develops a beautiful natural patina that makes every project completely unique.

Whether we’re fabricating a copper chimney cap, range hood, countertop, or decorative accent, each piece becomes more beautiful with the passing years.

Crafted for Mountain Homes

Luxury mountain homes deserve details that are as timeless as the landscapes surrounding them.

Throughout Ketchum, Sun Valley, Hailey, Bellevue, Stanley, Carey, and the greater Wood River Valley, we’ve helped homeowners, builders, architects, and designers create custom metal features that blend beautifully with stone, timber, glass, and natural materials.

From rustic mountain cabins to modern custom homes, our fabrication shop brings each vision to life with handcrafted precision.

Why In-House Fabrication Matters

Having our own sheet metal shop gives our customers advantages that simply aren’t possible with pre-manufactured products.

With in-house fabrication, we can:

• Create truly custom designs
• Ensure a perfect fit
• Match existing architectural details
• Maintain strict quality control
• Produce specialty pieces unavailable through manufacturers
• Collaborate directly with homeowners, architects, and contractors
• Deliver exceptional craftsmanship from start to finish

Every project is built specifically for your home—not adapted from something already sitting on a shelf.
