Longden Company has long been recognized as a leading cleanroom contractor here in New England and across the country, for both turnkey design/build and build-to-specification cleanrooms. We understand cleanroom construction and clean-build protocol, and we’re dedicated to providing contamination-controlled environments.
Since 1988, Longden has constructed cleanrooms ranging from Class 1 (ISO 3) to Class 100,000 (ISO 8) and varying in size from mini-environments to world-class semiconductor mega-fab installations in all segments (biomedical, pharmaceutical, semiconductor, manufacturing) of the cleanroom market. We have successfully completed projects ranging in size from small process isolators (6 square feet) to large semiconductor fabs (160,000 square feet).
Our experienced construction crews, along with our veteran project management team, assure that our clients’ projects are completed on time and on budget.
