Amco waterproofing - Not recommended

AMCO WATERPROOFING A company that I do not recommend. Their service is unprofessional. Promises are never kept when they are eventually made. After many attempts to remedy faulty workmanship and causing leakages where none existed before. Unable to repair these problems after many failed visits to site. Now they refuse to communicate with me, despite threats and giving them leeway to rethink their situation. Standard of workmanship leaves much to be desired. Not capable of solving ongoing defective work. Not honouring their guarantees.
