Business ProfileforPetersen Plumbing & Heating Co

We bought a newly built house in ********** ****. It came with a 1 year builder warranty. Before we moved in we were doing work in the basement when the workers noticed water on the floor of a bathroom. The workers saw Petersen plumbing employees and our builder in the street and relayed what happened. Petersen workers subsequently entered our house WITHOUT our knowledge to see what is wrong. They never told us they entered our house or what they did. 2 days later the whole sewage line backed up. At that point we found out by word of mouth that Petersen trespassed into our home. Through the warranty, the builder then brought Petersen back into our house to clear the blockage in the sewage line emergently.1 month later Petersen sent us a bill, not itemized for $282. They continuously refuse to show us footage of what was in the plumbing. They claim the blockage is not part of the warranty because they claim to have found tampons blocking the pipes. We had not lived in the house yet. Its a brand new house. We emailed and called Petersen twice complaining about their trespassing and their lack of transparency about the blockage. They are ignoring our emails and not replying back to us. Yet they have sent us 3 bills so far asking to be paid for the damage ensuing from their trespassing
