"There’s nothing like having the best of the best. I’ve used the other big security names before like Vivint and Brinks. They are OK.

Reinhold Electric Inc
Reinhold Electric Inc
We started in 1976, to provide quality and assurance to always satisfy the customer. We guarantee all of our work, and our employees deliver this proud craftsmanship. We also offer 24 hour emergency service. With a live answering service to take your calls, we have owners and electricians that are on standby around the clock.
"I really wanted to have a good experience with Reinhold. We’ve used them in the past and they did good work, we thought… recently our garage’s power stopped working, which is fed by a panel on the pole that they installed in August of 2022. We NEVER had a single electrical issue until after that pole was installed which is starting to make sense. A few months ago we began having electrical issues in our house, so we called Reinhold because we thought they did a good job when installing the pole that fell in 2022. The technicians that were out to see what the cause of the electrical issues in the house were said that the lines under ground were corroded (which may have been true), so we accepted to let them fix it. They hand dug by the electric pole, buried conduit and ran new wire to the house and everything seemed to be fine until we recently started having issues with the electric in our garage. The location where they dug and buried the conduit for the wire going to the house is in a very close location to where the conduit goes for the wires going from the pole to the garage. I called for an estimate and was told $5,000 worse case scenario which may be understandable considering that would include cutting asphalt, trenching, new conduit, new wire and labor so I get that. Upon receiving this news I decided to just take care of it myself. I went to the building department for our county to take the test to do residential electric work, paid for the permit to be pulled, had everything cleared with Missouri 811 incase I needed to dig and bought $700 worth of new wire. I pulled the old wire, saw that there was a break in the wire due to corrosion from water getting in the conduit underground so I started digging right where the conduit meets the pole that Reinhold installed just to see if there was a break in the conduit. Sure enough, there’s a small section of conduit that was crudely placed over where the old conduit underground is and the new conduit where they installed the pole. They had it lightly wrapped in what looks like some kind of landscape fabric (thought it was electrical tape at first). So there was no protection in the conduit against water getting in which was what caused the wire to corrode to the point of no longer working. Mind you, Reinhold is THE ONLY company we’ve had at our house for electrical work since owning the house. When I saw this piece of conduit being very improperly “connected”, I took pictures, and videos and sent them to the estimator who came out to give me a quote for fixing the electrical issue in the garage. He said he would give me a call back after speaking with the technicians that were there more recently to fix the electrical issue with the house as well as the ones who installed the pole in August of 2022. After speaking with them he said that none of them claimed to do that and that their technicians would never do something like that and all these denials of my claim. He then told me that he could come out and fix it for $500-$600 FOR A 3” LONG SECTION OF CONDUIT THAT NEEDED TO BE REPAIRED FROM THEIR PREVIOUS WORK. I am not the type to ask for free stuff from ANYONE, I’m incredibly happy to pay for good service by good people and I thought that’s what we were doing with Reinhold until yesterday. They completely denied the fact that their technicians made a mistake, and didn’t offer to fix the issue or anything. I was told that all of the technicians that have been on our property did not do it and that it would be $500-$600 to fix something they installed incorrectly. I understand if a technician didn’t remember every little detail from a job they did in 2022, but there is no integrity or accountability on their part with this issue. It was either done in 2022 when the new pole was installed or a few months ago when the new wire was put in with new conduit by REINHOLD."

"This company is absolutely fantastic! Tony is so professional and a really great guy. He bid me a price for some work that turned out to be much more complicated than originally thought. He did not try and increase his price and did the work for the pre-determined rate. In addition, I had a tv he was supposed to hang that was brand new in the box. When he opened it, he discovered the screen was shattered. I was able to return the tv and he is coming back out on a separate trip to hang it. He has really gone above and beyond. I cannot recommend him more highly."
