Constraction reviews in Las Vegas, Nevada

Huge thank you to Sigma Companies
My main breaker to my house gave out,needing for me to get the whole panel replaced.
Ron,Cristy,and Peter did an amazing job at communicating with me on everything & making sure my family and I were safe.
Thank you for your honesty and quick response to my situation.
Highly recommend Sigma Companies

We purchased a jacuzzi tub without realizing that it needs an outlet with a 220 voltage. We did our research and found Sigma on Yelp. They came and gave us a free estimate, and answered all of our questions. We gave the company the job. The workers came to do the job on time. They pulled the 220 voltage from outside power panel, and put it through the attic to get it to our second floor master bathroom. We were happy that all the wires were invisible. After they finish the job, the workers cleaned and vacuum the debris. In addition they went above and beyond by attaching a new plug to our new jacuzzi which was not part of the deal. The workers were very professional, so does the office workers that we came in contact with. I highly recommend Sigma.

If I could give 10 stars I would! Kyle from Sigma is the absolute man! I run a small biz here in Vegas and we tend to run into some serious electrical issues throughout our building and Kyle is without a doubt the most reliable, knowledgeable electrician I've ever worked with (and I've worked with a ton over the years). You're in good hands with Sigma.

Justin is top notch. Figured out my problems that other electricians could not. He is very professional, knowledgeable, thorough. Just can’t think of enough good to say about him. I am very thankful that I found him. His prices are very fair!

Sigma Companies is top-notch! Kyle, one of their electricians, deserves special recognition. His expertise and professionalism are outstanding. He quickly resolved our electrical issues, explained everything clearly, and left our home in perfect condition. Sigma Companies is now our go-to for electrical work. Highly recommended! ⚡👍

Aaren came and installed an EV charger in my home. He was friendly and efficient! The charger did not work initially but Aaren came back out with Wolf another tech and they were able to get my car charger working in no time. Everyone I interacted with at Sigma was friendly, patient and very helpful. I would highly recommend using Sigma to anyone needed an electrician.

I've used Justin with Sigma Companies on several occasions now ranging from EV Charger installation, to convenience outlets, GFI breakers, and a Ring Spotlight camera. I feel that their prices are reasonable, and the work is always done in the timeline provided to the expected level of quality. When dealing with permits, I've never had any issues during inspection. I would highly recommend. Thanks!

Great company to work with.

Truly a great company to work with A+++. Keep up the great work!!!!!!

The people here are very kindhearted, sweet and welcoming. The technicians want to solve your problem as quickly as they can, to get you up and running as soon as possible. Positive energy all around.

Tried getting a home charger installed for my EV they showed up late and had no idea where I wanted it to be installed. Then insisted they had to reschedule because it wasn’t in their “plans”. Completely unprofessional. DO NOT USE THEM

I recently acquired my EUV and they selected to install NEMA outlet. They provided 2 hours installation window (8 am to 10 am), which I don’t really understand why, but anyway installer showed up at 9:30 am. Installation was done in less than 20 mins. Since the installation I have been having issues with the NEMA socket overheating and the charger amber light turns on due to overheating as well. I have been in contact with them, however all they cared about is to charge diagnostic fees for an installation that was done less than 2 weeks ago. Still waiting for them to send their tech to check their poor quality installation. DON’T USE THEM and ask for a different company.

Expertise and Reliability in Electrical Contracting Services
When it comes to electrical work, we rely on the proficiency and professionalism of our partners. Since we specialize in low voltage and lack the license to handle high voltage work, we trust G3 Electric to get the job done right. Their track record speaks for itself – they consistently deliver top-notch service.

I recently acquired a car that included a complimentary Level 2 charger installation through Qmerit. G3 Electrical was selected as the contractor for the installation after accepting their bid and quote. However, my experience with G3 Electrical was highly disappointing and fraught with numerous issues.

Right from the beginning, I made it a point to clearly indicate in my order that I required a Saturday installation due to my limited availability during weekdays. It was explicitly mentioned in my order and even stated on their website that they provide installations on Saturdays. However, when attempting to schedule the installation, I was informed that they do not conduct installations on Saturdays. This inconsistency was frustrating, especially considering my specific request. Although I managed to find an available day on their automated calendar, I found it peculiar that I could schedule the installation on a holiday. Upon contacting G3 Electrical to confirm the appointment, they promptly informed me that they do not work on that particular day, necessitating a rescheduling for a few weeks later. Consequently, I had to arrange for my wife to take time off work to be present during the installation.

As if the scheduling challenges were not enough, further complications arose when reviewing the paperwork sent by G3 Electrical. I noticed that it stated an installation of an outlet instead of the hardwired unit we had discussed and agreed upon. When I raised this concern with the office manager, she assured me that it would not be an issue and encouraged me to approve the paperwork.

On the day of the installation, the assigned installer displayed a disrespectful and unhelpful attitude towards my wife. Multiple points of confusion arose, and when questioned about them, the installer repeatedly responded with, "That's not my job. I am just here to do what the paperwork tells me." The main issue stemmed from the fact that the paperwork specified an outlet installation rather than the desired hardwired unit. The installer further stated that they lacked the necessary wires and breakers for a hardwired setup. Following another conversation with the office manager, it was decided to proceed with the installation while planning to upgrade the breaker at a later date. Despite my wife's repeated instructions regarding the desired hardwired location, the installer negligently installed the unit on the wrong side of the garage, offering the excuse of running out of wiring.

After the disheartening experience, I voiced my dissatisfaction to the office manager and specifically requested a different installer for any future work. Additionally, I emphasized the need to rectify the installation error by relocating the unit to the correct spot. To my dismay, the office manager stated that they would be unable to move the unit and cited concerns about the holes left in the garage. Despite my willingness to overlook the holes, no resolution was reached, and the unit remained in the undesired location.

Furthermore, when G3 Electrical returned to upgrade the breaker, it was the same installer who had previously displayed a disrespectful attitude towards my wife. This was despite my explicit request for a different installer and the office manager's assurance that a different individual would be assigned.

In conclusion, I strongly advise against engaging the services of G3 Electrical. I can only award them one star, primarily because they managed to install the system, and it is currently operational. However, my overall experience with the company was marred by numerous headaches and disappointments. I regret not selecting an alternative company that would have installed the unit according to our specifications and provided a more professional and satisfactory experience. Additionally, I am concerned about the permit, which still indicates an outlet installation instead of the agreed-upon hardwired connection, potentially leading to future complications.
