Called back in October to inquire about a possible estimate. They immediately wanted to schedule it. I asked repeatedly if there was a charge for an estimate and said I did not want one if there was (most reputable organizations give free estimates). They did not answer and proceeded to schedule someone. When they arrived, they said nothing about cost up front, but immediately began to give an (inflated) estimate for a bare minimum job. After completing the estimate, the gentlemen gave me a bill for $45. I told him the above story and said I had no intention to pay. I immediately called Halpin and recounted the same info. The young lady I spoke with said she would talk to someone and let me know (although her attitude mostly indicated she had heard it all before and she just wanted me to pay.)
I have heard nothing from them since, and assumed the matter was settled. Today I was left a message (convenient calling in the middle of the day when working folks aren't home—amazingly, no one answered when I returned the call at 4:30 p.m.) from a Lisa at Halpin regarding my, so-called, outstanding balance. She claimed to have sent several emails, as if such amounted to some kind of legal notice (I've never received any such email), and wanted me to call and arrange payment so that they could avoid turning the matter over to collections.
I will not be bullied by scammers and will not pay for a service I did not authorize with knowledge aforehand of the cost. I suggest to all who might consider engaging these people that they take my experience into account and run the other way.

Very unprofessional. Showed up and we had another company there who had set a time window, so we didn't know for sure when they were coming, shouldn't be a big deal, smart people get at least 3 quotes! Quote was over 175% higher than any other quote ( and we had 3 other quotes). Wasted our time with unprofessional behavior. I would advise going with another company.
