I had a good experience with Henniker Septic when they thawed
the frozen line between my tank and leachfield. At the time, they
mentioned that my distribution box really ought to be replaced.

With the ground workable, I called them to see about having that
done. It took three calls over a week's time, each with a promise
that they'd call me back, before I could talk to anyone about it.
I wanted to discuss whether a tree stump near the line would be a
problem (which two tree companies had told me it wouldn't); the
woman on the phone didn't seem to get it. Finally they told me that
a man had come by the house and said it'd be fine.

They mailed me an estimate (which the woman on the phone didn't even
know had been done), and I sent them a 50% deposit on the job. Without
even discussing scheduling, I get a phone call at 7 AM (which was 4 AM
for me, as I was in California, but they didn't know that) saying they'd
be out to do it that day. I informed him that I wasn't home and we
hadn't made an appointment; I'd call them when I got back. A few days
later he left a voice mail indicating a day that he could do it.

When I was home, I called them to confirm that date. Afterward, making
some small talk, I mentioned to the woman that I thought it was funny/weird that they operate separate businesses (septic, sewer, etc.) with the same people, and yet they have different office hours. That got the owner on the phone, and he was all bent out of shape because I used the word ""weird"". I told him I was sorry for using that word, and he said my business wasn't worth it and I'd been such a headache for his company.

Good riddance.

P.S. My deposit check (for half the estimate) was paid by my bank on 8/19. On 9/3, I called to ask that it be refunded; they said they'd call back. On 9/5, with no callback, I called again. A different woman answered, she said she knows nothing about it (seems to be the norm for their office) and guaranteed that I'd get a call back today...

Got a call from the owner tonight; he says he sent me a refund check on Tuesday (9/3) when he saw the message. I don't doubt that he did. But I have to wonder about how this business keeps records or if they ever even talk to one another.

Was given a surprise at the end of the work. The bill was over 20% above the estimate without warning and they wanted payment in full right away. I never approved the added cost and was never told about it. Then when I was asked about it Nate got all upset telling his office I refused to pay and made suggestions of taking me to court. The work started with a 24 hours notice they were coming to dig up my yard. I had previously told them several times I would like a couple weeks notice. Nate, one of the owners of the company got all pissy and left without resolving the concerns I had. Not even an acknowledgement that he could have warned me and tried blaming me that I didnt know about the extra cost. I also read reviews in other place, after the fact, that this is not the only time they have done this. I am now on a payment plan with them to pay the remainder and they dont care and have no interest in trying to do what is right. If I had know this was going to be the outcome I would have never asked them for help.
