ABOUT US

At McCastle Cleanroom Construction, we specialize in building high-quality cleanrooms and modular buildings for industries where precision, safety, and compliance are non-negotiable. Since 2018, we’ve completed more than 185 cleanrooms and modular projects, totaling over 1.2 million square feet across 22 U.S. states, and installed more than 10,000 fan filter units (FFUs/HEPAs).

​

Our team brings hands-on expertise with eight major wall systems—including Starrco, Portafab, GCON, Plascore, Puracore, Technical Air Products, and King Span—making us one of the few construction companies with such comprehensive experience. We’ve proudly delivered cleanrooms for the medical, pharmaceutical, aerospace/defense, automotive, packaging, electronics, and GMP sectors.

​

We work hand-in-hand with your Cleanroom Design Team and General Contractor to ensure seamless coordination of all trade work throughout the build process.

​

Our work is guided by five core values:

• Integrity – We do what we say.

• Schedule Excellence – Meeting deadlines through planning and accountability.

• Quality Construction – Built right, with customers engaged every step of the way.

• Safety First – OSHA standards followed on every project.

• Customers for Life – Success built on repeat business and trusted partnerships.

At McCastle Cleanroom Construction, we’re dedicated to building cleanrooms right, on schedule, and with lasting quality.
