The leaders in Cleanroom Design, Manufacturing and Installation
Cleanrooms preserve the safety and integrity of production processes across diverse industries. From pharmaceuticals, to medical devices, cleanrooms control the unwanted variables that could result in serious consequences.
With stakes this high, your cleanroom project demands attention, transparency and precision.
The only cleanroom provider who puts client experience first, for every client.
Innovation is happening at breakneck speed—companies can’t afford anything except an exceptional cleanroom solution to stay ahead.
That’s why we champion the client experience above everything else: Our proprietary process marries communication with expertise, offering a fully transparent, tech-enabled experience from idea to execution. We stay two steps ahead so projects don’t fall behind, foreseeing risks and finding efficiencies to make sure every clean space we build can fulfill its purpose as quickly as possible.
Overall, I was very impressed with the management team at CleanSpace and their hands-on approach from start through completion. The coverage and flexibility of the team is very impressive.
