David William Wisniewski Sr
Owner
Doesn't even deserve one star - but you have to give at least one to write a review. I would not allow either Wisniewski (Jr. or Sr.) to do any work on my property of any sort. The week of May 15th Dave Jr was replacing a water main on our property, with Dave Sr stopping by to check progress throughout. In the process of that work, Dave Jr. hit the gas line that serves the generators on the property. We wanted to call the gas company to repair, but he promised he was trained and knowlegeable and could fix it himself. After replacing the damaged section, we asked him not once but several times if he needed to use our air compressor to test the line - he said that was not necessary as he had already checked his work by spraying soapy water where he had repaired. 24 hours later we had an explosion and major fire in a building on the property - resulting in two people in the hospital. And to add insult to injury they are now claiming they have no responsibility/liability and are avoiding dealing with this at all. And after all of this we have found out that Dave Jr. is only an apprentice plumber (something we did not know nor did he mention) and he does not have any insurance. Dave Sr. is claiming that he has nothing to do with it either - really???? then why was he out to the site multiple times to check on things? and why does Dave Jr. say that he does the smaller jobs for his dad???
BEWARE!!!!!
