My company has been providing security services to a construction firm for over 5 months. We patrol the area and protect the site from being vandalized and from theft. The construction company has not paid me for our services. I have contacted them multiple times and every person I speak with gives me the run around. Can I place a lien on them? If not, what can I do to get them to pay me? I had to sign a waiver of Liens for another construction company that I provided services to before which makes me think I can place a lien on this current construction company.
