Worst place to call if you want heat. We had just bought a house and needed the furnace fixed…read morebecause there was no heat in the house. I called on a Saturday and scheduled an "appt" for Monday at 9:00 am. No one ever showed up or called? So I caled the office and the lady said He is Commin. So 6 hours later no one ever showed up and so I called again. I said guy never showed up and she said well I gave him the slip to go. She said he was somewhere else and he will be Comming and then I just said no one ever called me to let me know and I wasted all this time waiting for a no show and if this is how you run a business I don't want you  working on my furnace. And she said ok. I was so discusted with this situation and still had no heat so I called another heating service who came out right away. Thanks yeagers for nothing!!

We have a slow sewer! A camera was placed only about 15 feet into a pipe that is at least 50 feet…read morelong. A diagnosis of a broken pipe in that area was made. There was some wetness around downstairs toilet and it took about 5 minutes to replace the wax ring. We were told that a person would schedule for the pipe repair. Seeing that we were charged $ 800 for a basic service , we decided to dig ourselves. No break!! Just a lot of work for us and a high price for the wrong diagnosis! As always! Buyer be ware! We were not given an itemized bill. i think at the time we were to shocked to ask!

I was experiencing a very strong sewer gas smell in my home that ultimately ended up being stagnant…read morewater beneath the foundation. Until it was finally determined though, the smell and the symptoms it was causing, required me to keep all my windows open during cold, snowy weather. Brian Hale and his crew came several times to try and help me figure out the cause because I thought it was a sewer gas leak. They were all very patient and knowledgeable with reasonable and fair pricing. They tested the indoor plumbing and felt the issue was below the foundation (which did end up being the case), which was outside their scope of work since it wasn't a plumbing issue. Brian in particular was very respectful, humble, knowledgeable, and helpful in answering my many questions as I was desperate to find a cause and solution to the problem. I would definitely highly recommend and hire them again for plumbing issues due to their professionalism, respectful and helpful attitudes, plumbing knowledge, quick response, and fair pricing. I also called them again this morning because I had an emergency water pipe breakage. It was a Saturday morning, so they weren't technically in, but Brian still called me back within 5 minutes to see if I had found help yet. Highly recommend!
