STS Electric has been servicing our high-rise building for about 3 years. They have been instrumental in updating / servicing our electrical wiring, circuit breaker panels, parking lot lighting as well assisting with inspection requirements for electrical items. There customer service is outstanding! Sam, the project manager is always accommodating and takes his time explaining what the problem is and discussing what options are available to address the issue. Every step of the way, he provides pictures and is in constant contact with the electricians he sends out and our management team. The Electricians are knowledgeable, hard working and precise. Ana, in the billing and scheduling department is always kind and willing to work with our budgetary and payment needs. I would highly recommend STS to anyone looking for Electrians with integrity, fair pricing, who provide exemplary service.

AMAZING PROFESSIONALS!! Anna and her team of electricians were very thorough in explaining what needed to be done and why. They operate with honesty, integrity and also clean up after themselves, lol. I have used their services twice in the past few years and would happily encourage others to employ them as well. Extremely satisfied customer here!!

Sarah Bjick Duda
So happy STS was recommended to us! We had a tricky electrical situation and they came up with a safe, processional, thoughtful, and innovative solution that saved our kitchen cabinetry. Highly recommend this company if you want to ensure the electrical work is done right. Super nice team, too!
Shizue Brochard
I have never felt compelled to leave a review before, but Sam and STS just did some excellent work for us and I need to say that everyone who needs an electrician should be looking at STS Electric first. They have been out here a few times and have done amazing work each time. This last time Sam replaced an outlet that had been wired incorrectly and had actually caught fire. He explained every thing he was doing, and the work is flawless. I can sleep better knowing it is now corrected.STS is the first company everyone should be looking at. Fair prices, great techs, and just overall amazing service from beginning to end!
Tyler Corfield
Top notch! Mike and his team did an amazing surveillance installation for my 800A service for my restaurant. Great communication. Great clean up afterwards as well.
Kelly DeJesus
We called STS out of desperation at 11 pm when our smoke detector system was malfunctioning and setting off our Xfinity alarm. When we called, the alarm had triggered about 100 times. Sam called me back within 5 minutes and walked me through how to disable the non-Xfinity system, which was causing the issue. He stayed on the phone with me for several minutes to ensure the alarm did not trigger again, and he offered to have me call him for the next few hours of the problem continues. Sam was super friendly and helpful.
Nicholas Joseph
David & John did a great job today getting my new hot tub wired in. They even adjusted to some last minute changes I made in the original plan without any complaints. Everything is working perfectly and looks great. Will be using STS Electric for any electrical needs going forward.
Willard Dias
Thank you to STS Electric! We were having power issues with electric services to half our house. STS Electric sent one of their electricians out very quickly and discovered that it was a Comed problem (even though ComEd said everything was okay). The electrician helped us by working his magic with some of the wiring to get us back up and going while ComEd solved their part of the problem. Good work, great price.
Blake Lee

Reliable, cost effective, trust worthy, professional team. After buying our first high-end condo in Chicago we decided to make some electrical changes including installation of chandeliers, new fans, outlets replacement, etc. We used STS Electric for the first time and we were very impressed by technicians exemplary performance. They were on scheduled time, very well organized, respectful, layed plastic sheet inside the condo to avoid carpet damage, and very professional. Their work quality was precise and our visitors appreciated the quality of workmanship. I would highly recommend them for any electrical work and we will use them again.

STS Saved us! They were responsive from the first call, came in the window designated and gave a reasonable quote to take care of our work. Being family owned, I felt like they really cared about making sure we were satisfied with their work. I would highly recommend them and will definitely use them if we have a need in the future.
Zakia Ejaz
Professional, courteous and competent would easily describe all encounters I had with their staff. Our electricians were Alex and Mike. They spent several days completely rewiring our 90 year old home and I'm delighted with the outcome and with their professionalism and knowledge. I asked lot of questions and had some very specific ideas on how I wanted some things done and they were patient and helpful at the same time they kept moving the job along. When employees have great customer service skills you know that is the culture at a business. As a result of great workmanship I am STS Electric client for life.
Viqar Aliuddin
I am very happy with the work provided by STS Electric. They were responsive to our request and communicated with us on phone and email to keep us informed of arrivals and scheduling. The friendly and knowledgeable staff took the time to answer our questions and understand our concerns. They arrived on time and efficiently completed the requested task. We will definitely be using them in the future for any additional electrical work.
Kayla Minkoff
Great service, and quality work.
Destini Taylor
I normally do not write reviews, but this is an exception I had to make because I had such low expectations prior to be calling this company. My experience at the time was I had been stood up by two different companies and I guess I figured I would have the same experience with this company, but boy was I wrong. I called and spoke to a pleasant woman who took down my information. The lights were flickering in the home and ConEd told me I had to hire an electrician to come out for that. The woman said she would have someone call me back and within 15 minutes I received a call from a woman asking me for more details. I shared my previous experiences with her and she sounded so empathetic and in fact sent a technician the same day. The service was affordable, the technician explained everything to me and was patient for the two thousand questions I had. I will definitely keep them on speed dial if I should have any electrical concerns in the future. I already gave this number to a couple of my neighbors that were looking for reputable electricians.
Dedicated Office
Absolutely amazing service!
Michael G.
STS Electric did an amazing job on my new house as well as many past smaller projects. I have used them for years on everything from a ceiling fan replacement to rewiring an old apartment that had cloth wires to my recent gut rehab. This job is now my home and I love the work they did. They are always very precise when it concerns the details of placement of the lights as I am very particular and they understand and make it exact.I am mostly a DIY guy who grew up in the construction industry but I usually don't do bigger electric jobs out of safety concern and my inexperience with "the code". I cannot rate them highly enough when it comes to professionalism and workmanship. They are responsive, punctual and clean up after themselves. I have recommended them dozens of times.
Tania Correa
I want to recommend Alex for superb troubleshooting skills, he was able locate intermittent power failure for section of my home. He was able to fix on he 1st and only service call.
Debra McCray
Power in 5 walls went out in the middle of the night. We tried tripping the breakers and no luck. We called STS Electric Service and Mike and George came out. They were very pleasant to deal with and explained everything as they went along. Mike found wiring burnt behind wall in the circuit and charred outlet behind my office table in study. Hey replaced all the wiring as needed and also fixed the drywall as they had to open some walls to replace the conduit. Very professional. All the drywall work was done perfectly… they just left for me to have it painted. Fixed and all power was ok. So thankful it did not cause a fire. Thank you Mike. I will call them again.
Melissa Coleman
Alex and his crew were fantastic. We had some major electrical issues at our building. We have 200 units in the building and had multiple electrical shorts in 4 units. Our regular electricians, STS Electric, were dispatched immediately. When they arrived, they started working on the problem right away and assured our unit residents that power will be back the same day. They fixed the electrical issues and all residents were very happy with their work and how they clean up behind themselves. Since I am the property Manager, I have to make sure the contractors I hire are top notch and always deliver services on time.
Pavel Stoev
STS is the most professional electrical contractor we've dealt with, with great attention to details and thoughtfulness. The project was to rewire existing residential home and we couldn't be happier with results - work was also done on time and within budget. We couldn't have asked for anything more; we'll be using them again on future projects.
Fatima Mohsin
Eddie went out of his way to make sure my job was serviced on the same day I called. I was impressed and very grateful, Jose and Alex completed job very efficiently. I’ve scheduled a meeting with them for estimate on future job. Thanks Sts Electric.
Muhammad Motasim
Well done. Mike came over the same day that I called. He looked over the job and reviewed all connections and installed the system. He was very professional, prompt, courteous and knowledgeable. I will look to him again for electrical work in Chicago.

Would recommend to others. I will continue to use them for all electrical issues I have on my rental properties. Reliable and prompt service all the time.
Jpark Blo
These guys did a fantastic job! They are very professional, and timely. I had them replace my old fuse box with a breaker panel, and a couple of other electrical miscellaneous jobs.They met all of my expectations, as well as rewiring my house that had old cloth wiring. These electricians are experts with old wiring.They will be doing all of my electrical work from now on. If I could get the rest of my contractors to be like them, building our new home would be a walk in the park!Thanks guys!
Jose Pesado
