Coral Environmental did work for us over an 8 week period. It was to assist us in dealing with a very difficult work environment. Coral carried out both air sampling and swab testing on a weekly basis to ensure our hygiene measures and procedures were effective in dealing with what was a very high risk and delicate situation. Coral provided required reports on time on a regular basis and responded in an extremely professional manner. I have no hesitation in providing a reference for this company.
