I am writing this complaint to draw attention to both the low quality of work and the horrendous customer service I experienced with M. Daddio Builders.
I had a roof leak in 2021 that was fixed quickly and efficiently by Chandelle Roofing company. Upon discovering a new leak this year, I reached out to them again. They contracted the work out to M. Daddio. I was suspicious, but being a generally trusting person, I went with it. I did express concerns over the cost structure sent to me by M. Daddio (see attached contract), and nobody responded to my email. Again, I was too trusting, and despite my anxiety over who would be sent to my house and the estimated cost for repair (which nobody gave me, despite the contract referring to an estimate), I trusted that it would be similar cost and quality to the original repair.
I was wrong. Not only was the cost more than double what the original leak cost to fix, the leak was not fixed. What had been a very slow leak got significantly worse in a short span of time.
When I reached out to M. Daddio to ask how they could help me, they replied that they would return to fix the leak at the same hourly rate as the previous failed repair. I understand that there is no guarantee when it comes to roof leaks and that they can be tricky to fix. However, the fact that the leak was made worse, and then M. Daddio was not willing to decrease the rates in the slightest to fix what they had made worse, begs the question: did they intentionally fail to fix the leak, hoping a young, single female would fall for it and end up paying them twice?I understand that I am partially at fault here. I should have refused to allow anyone to do work on my house until someone replied to my email with an estimate, and I should have trusted my gut when it seemed questionable that a company other than Chandelle Roofing was coming to fix my roof. However, I am a generally trusting person, and didn’t want to bother anyone. Now I feel I have been taken advantage of and ripped off.
Despite the high cost for low quality work, my biggest disappointment was how I was treated by Mike Daddio when I called to calmly voice my concerns. I was interested in having a dialogue and perhaps reaching a compromise. While I felt that M. Daddio Builders could and should come back to fix the leak for free, I understand that they would not want to do that and I was more than willing to compromise. However, before I could even finish a sentence expressing my thoughts, Mike Daddio rudely interrupted me by talking over me and would not allow me to finish a sentence. Then, despite me requesting that he simply hear me out and then I would be happy to hear his viewpoint, he called me unreasonable, hung up on me, and then refused to respond to my phone calls and emails. When I finally got a reply after over a week and multiple attempts to reach Mike, he offered me a measly $500 credit and tried to cover himself by saying that his company had recommended a new roof, and I had opted to fix the leak. I asked Mike to find written proof of his claim, and he was unable. Nobody at M. Daddio builders had even mentioned the possibility of a new roof, let alone recommended it. The fact that Mike attempted to lie to me in order to escape responsibility, after already having treated me disrespectfully, is just poor business practice.
I found Mike Daddio to be incredibly unprofessional. He is clearly more interested in making money than he is ensuring the quality of his company’s work, and he has no concern for the needs and concerns of his clients.
