Testing + Certification

The Cleanroom You Need. Guaranteed.

There's nothing more important to the operation of a cleanroom than proper certification. Your cleanroom must meet testing requirements for your specific ISO Class level before you can begin production. Modulus Cleanrooms is dedicated to delivering the cleanroom you need, and we stand behind each of our cleanrooms with quality testing, certification, and cleanroom validation. We provide cleanroom testing and certification for clients looking into renovating or updating existing cleanrooms and certify each of our new cleanrooms with quality cleanroom testing completed by a reputable third party.

“Seth was incredibly responsive and personally involved from quote all the way through certification sign off. It was refreshing to deal with a company where the principle is involved from day one through the completion of the project. From the bid perspective, Modulus did the best job to utilize the limited space that we had to worth with. Modulus had to coordinate their work with the other remodel activities including ethernet cabling, HVAC, electrical, etc., and did so seamlessly without incident. The overall quality of their work was excellent and they clearly put the customer first."
