About Us

A New Name. The Same Team You Trust.

Fortify Building Solutions is becoming Mueller.

That means you’ll start to see the Mueller name appear, one Fortify store at a time across our network through 2027. While the name is changing, the people, products, and service you rely on are staying the same, with even more support behind them.

You’ll continue working with the same local team you know and trust—now backed by the strength, scale, and 90+ year legacy of Mueller.

Fortify Is Becoming Mueller

Beginning October 1, 2025, Fortify stores started transitioning to the Mueller brand. This gradual transition, planned across two years, unites our network of retail stores under a single, nationally trusted name, strengthening our ability to serve contractors and builders from coast to coast.

What's changing: Our name and brand.

What's staying the same: Your team. Your products. Your service. Your support.

As your local store transitions, you’ll see updates to signage and branding, but your day-to-day experience remains consistent, with added capabilities and expanded support.

What This Means for You

Same Team — You’ll keep working with the same people who know your business

Same Service — The responsiveness and reliability you depend on continues

More Ways to Get What You Need— Expanded locations, inventory, and support

Proven Experience — Decades of know-how behind every project

You can continue placing orders, contacting your local team, and doing business exactly as you do today.

FOR CONTRACTORS & TRADE PROFESSIONALS

Your account, pricing, credit terms and local contacts remain unchanged through the transition. If you have questions about your store's transition timeline, reach out to your local sales rep.

Local Expertise, National Strength

Your local team still knows your region, your codes, and your project types. The Mueller name adds national credibility and supply chain strength behind every order.

Built on a Strong Foundation

Fortify Building Solutions was formed by bringing together Heritage Building Systems, Metal Depots, and Reed’s Metals—trusted names with decades of experience in the metal building industry.
