“Scoring Verde 10 out of 10 is not enough to show how excellently they undertook the remediation works of our oil tank leak.  Our Project Manager, Clare Whitely was excellent, as was all the remediation team who really impressed us. Their work was very neat and tidy and they left the area clean every evening.  I would certainly recommend them to anyone in our position.” More Testimonials
