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."

FAQs for electrical wiring or panel upgrade projects in Maryland Heights, MO

While homeowners with substantial electrical knowledge might technically attempt a subpanel installation, most local building departments require permits and inspections for this type of work. Professional electricians understand local code requirements, can obtain necessary permits, and ensure the installation meets safety standards. Given the significant safety risks associated with incorrect electrical work, most homeowners benefit from hiring a licensed professional.

A standard subpanel installation takes an average of four to eight hours. This timeframe may extend if you're installing multiple subpanels or adding specialized circuits like those for spa equipment. Factors such as difficult access points, complex wiring paths, or permit processing times can also affect the overall project duration.

Adding a subpanel doesn't directly reduce electricity consumption or lower your utility bills. A subpanel simply redistributes power from your main panel to additional circuits. However, organizing your electrical system more efficiently may help prevent overloaded circuits and the associated problems. For actual cost savings, consider energy-efficient appliances and lighting instead.

The appropriate subpanel size depends on your specific electrical requirements. Consider the number and type of devices you'll be powering, potential future needs, and the capacity of your main electrical panel. An electrician can perform a load calculation to determine the most suitable amperage rating for your situation, ensuring you have adequate power without overpaying for unnecessary capacity.

A main electrical panel connects directly to your utility's power supply and contains your home's primary service disconnect. It distributes electricity throughout your entire house. A subpanel, by contrast, receives power from the main panel and redistributes it to a specific area of your home. Think of the main panel as the primary distribution point and the subpanel as a secondary branch that extends your electrical system's reach.

While electrical upgrades aren't as immediately visible as kitchen or bathroom renovations, they can contribute to your home's functionality and safety. Prospective buyers often appreciate updated electrical systems that can accommodate modern power demands. A properly installed subpanel that provides additional capacity for workshops, home offices, or future expansions could be an attractive feature for certain buyers, though the direct impact on home value varies by market.
