"LP came to service my water system on 4/4/2023. The service tech indicated I had a possible issue with my sump pump as he poured water and sediment from changing my cartridge/filter into the sump pump. He asked if I wanted an LP plumber to come out and to see what the issue was. I agreed. Plumbers came. 20-minutes later they left my home and I received an electronic invoice for $550.00. They never told me what was wrong. They did not provide an estimate to replace. They did not request a signature to accept the estimate and okay to perform the work. They did not request a signature for me accepting the work that was supposedly performed. When I opened the electronic invoice, my name had been forged in 2 areas. The invoice did not list what brand/manufacturer of sump pump was installed. The invoice did not have a price for the labor. There was a $100 deduction but no reason provided. When I called LP, a was switched over to a representative. She stated they could not provide the sump pump information I requested. No reason as to why. But wanted to know if I wanted to pay my bill. I did pay, but thought more about it and filed a complaint with the Better Business Bureau. My request was simple: provide a new invoice with the manufacturer of the sump pump. It would be a good thing to have in the event the supposed NEW sump pump failed. Odd that another well known contractor who replaced this years ago, gave me their invoice with the name and manufacturer and brand name/model of the sump pump that was determined defective by LP. I still have that receipt but odd that LP, supposedly a professional company, literally refused to provide the information that I requested. LP did reach out but I did not take the call on my cell and was out the next day when they called a landline. Their rep replied was everything looked reasonable but they, LP, NEVER, and STILL HAS NOT provided the information I requested. The name of the new sump, model number, etc. that I would need should the unit fail after LP had performed the work. If the unit failed, how would I ever be able to call the maker, e.g., Kohler, and see if they would honor a warranty if it did fail. How hard would it have been for LP to honor this request? Because I, a senior citizen did not contact LP by phone, the BBB closed the complaint. Instead of requesting that LP provide the required information, they closed the complaint. Makes one feel like they were totally scammed and the reason they didn't know or want to provide the information is that didn't actually perform the work. Another senior - SCAMMED."

"Had an emergency clog that flooded basement bathroom. Perry came over and we thought he was awesome. He seemed very kind & was happy to help. Got rid of the clog and even fixed our garbage disposal. Forked out a little over $380 but didn’t care because I was relieved things were fixed. Unfortunately Perry didn’t connect the hose back up to our washing machine so when we ran it, our basement flooded even worse. Contacted Perry to see if he had anything to at least help suck the water up and asked if PlumbCrazy covered this sort of thing. He replied and he said “For all I know you moved to clean and left it off.” I promise you we didn’t move anything yet. It definitely wasn’t intentional that it was left off. However, I am very frustrated that something like this can happen and he doesn’t want to take any responsibility for it. Our carpet, my speakers and a few other items were soaked from this incident and now I’m over here wishing I didn’t choose to do business with this company. I hope in the future Perry double checks that he hooked everything back up so no one is left on the situation we are."

From average costs to expert advice, get all the answers you need to get your job done.

Find costs to repair a gas line and plan your budget based on the problem, from excavating for a new line to making a minor repair to an existing one.
