We also offer a same day service to ensure customer appreciation and overall customer happiness. Since 1978, Don't be left in the dark, call Wesling Electric Corp. today!
"I am so pleased with my choice to hire Wesling Electric. Robert was polite, professional and easy to work with. Of the three bids I received for my project, his bid was in the middle price-wise. I was confident hiring Robert because he seemed very competent and would be the same person who would be coming back to do the work. I didn't have to worry about job details getting mixed up or miscommunicated between a project manager and worker. As of March 2022 Wesling Electric was booking one week out (this was the same timeframe for all 3 companies I spoke with). The job took less than a day. Robert confirmed how I wanted the new switches to work and didn't mind me being picky with the placement of a ceiling fan. I will definitely contact this company again for future electrical projects in my home."

ERKER SECURITY SYSTEMS INC
ERKER SECURITY SYSTEMS INC
Erker Security Systems, Inc. was started by Paul T. Erker in 1994 and is still locally owned and operated. Since then, we have grown into one of St. Louis’ top residential / commercial security companies, serving with excellence and professionalism.
"I contacted Erker Security Systems when the security company we had employed for 30 years was unable and unsuccessful in upgrading and modernizing their previously installed alarm system in our home. After 6 to 8 weeks of frustration with the old alarm company’s attempt to replace devices, and install the control panel and alarm system I was forced to contact another alarm company. Paul Erker, President, and Larry Colemire, Vice President, from Erker Security were attentive to my questions and desires for modernizing my equipment. Mr. Erker immediately responded to my phone call and Mr. Colemire came to my home that very day to assess the situation and status of the alarm system. Mr. Colemire was able to define the problems associated with the faulty and incomplete attempt to update my system and evaluated the condition of the devices and wiring of the old system. Subsequently a team of three very competent installers successfully wired the master panel, replaced defective devices, and programmed the computer to monitor our new alarm system in short order. While the previous alarm company was unable to use their earlier placed hard wired devices and substituted wireless devices in their stead, Erker’s installers were able to trace the previously placed wiring so that all the wireless devices were converted to the preferred hard wired status. The new, updated system has functioned flawlessly and has exceeded my expectations for modernizing and upgrading my home alarm. All the personnel involved in the company from the front desk to the top of the executive suite we’re kind, courteous, professional, knowledgeable, and were interested in ensuring the successful installation and functioning of the alarm system. Mr. Erker himself contacted me on several occasions to ensure I was satisfied with the work and functioning of the alarm. It isn’t every day that the President of a company takes a personal interest in the individual customer’s needs and desires. This company is truly one in a million. I recommend Erker Security Systems without hesitation to anyone interested in purchasing an alarm system for their home or business."

"I was on the market for a security system and this one seemed easy enough to install.......went through the process and some of the window sensors were not working. I called Customer Support who was very friendly and we went through the entire process again...this time other window sensors did not work. This went on for a week or so...then the door senors stopped working....than the motion sensor stopped working...at no time in over a month did I have a fully operational security system. As I was about to return the system I was told they have "new" sensors and they just realized they received a bad batch and are working with another company.....Gave it a try....and same issue returned....some sensors worked....some didn't. I finally returned the system and stopped getting emails.....only to find that they were still billing my credit card even after I returned the equipment. Very nice people and very understanding.....unfortunately their product is not up to par. While we do have a large home, it's an open concept and the sensors that weren't working were no more than 15ft away from the base. The previous owners of my house had a wireless system with no issues at all.....I'm going to be using that company going forward."
