Ria A.

I hired Del Core electric and we were beyond pleased with their work. I do not usually write too many reviews but they definitely deserve a great one. I just bought a new Tesla and Sebastian did a stellar job at installing our new Electric Vehicle Charging Station. I am beyond pleased with their work and as they took the time to really listen to our needs. My new EV charging station looks awesome and it works perfectly. Sebastian and his team were incredibly professional and Cynthia helped me so much with explaining to me the entire process. I definitely give them 5 stars. We will also only be using them for all our future electrical needs. I highly recommend this company!

Initially found Del Core Electric on Home Advisor. Was looking for two spotlights installed on either end of the second-floor soffit in the backyard, + 8 recessed lights: 4 in the second-floor front yard soffit, two at front door, & two over each garage door. September 2018 installation went smoothly, remote access has been a Great experience via the Lutron mobile app. Now, a couple years later, I reached out to Sebastian to install an exterior receptacle. Received a quick text back suggesting: no problem. We went back and forth to pick a time that worked. During these exchanges, I mentioned that one of the soffit lights he installed started blinking and asked that he could bring a ladder to check it out. Received one last note to confirm an arrival time, then radio silent & no show. Sebastian went MIA - no further response, even after additional attempts to contact. This was in July. I reached back out in September to follow up Again. Initially he was only responding to txt, not answering the phone. Suggests that he has been Swamped. Few days goes by, so I reach back out again. Got a text back suggesting he might have some time the following afternoon. That was the last we heard from Sebastian. I have since called and left voicemails in addition to txt messages. No Reply. If your looking for an Electrician for only one project, then sure Sebastian might be able to help. If you’re looking for an Electrician that’s reliable, shows up when promised, professional with responding to calls or text messages (Close of Business, or the following day is more than acceptable to me), then do yourself a favor and find someone else. Sebastian’s business profile suggests he Prides himself on strong reputation and providing great service? Do not think so. Only so many times a customer can reach out w/no response. Will be taking my business elsewhere. Someone else may be interested in installing our landscape lighting, installing lighting in our remodeled kitchen (next year) & help us understand if the Tesla Powerwall is an option for our home.

Service Provider Response

Hello [Member Name Removed], I deeply apologize about the scheduling error. I made a human error and didn’t see the project down for that specific day. We committed to the project a few weeks prior and a scheduling error transpired during the time. We always confirm projects the day before. I tried calling you several times the day this occurred, and left voicemails apologizing and trying to remedy the situation after receiving your phone call. I also followed up a couple days later as well. We are a reputable company that prides ourselves on putting the customer first. Please don’t hesitate to call back, I would appreciate it and be willing to reimburse your time accordingly. Again, sorry for the inconvenience and thanks for holding us accountable, we will make sure this never happens again!

The entire experience was perfect from initial call through free estimate to service upgrade. Sebastian and his crew were very professional, efficient and neat. They made sure the job was done right and corrected small problems in the original set up like no cable grounding to ensure everything was clean and safe. They will get any electrical work I have in the future. I highly recommend them.

A+! Sebastian and his workers were more than accommodating. I needed a 200 amp service upgrade done and they gave me the best quoted price. I scheduled to have the work done on a specific day but I had to cancel because something came up. Sebastian was more than understanding and rescheduled for another day. Communication was great, they showed up on time , cleaned up and were very friendly! Couldn’t speak more highly! I have them coming back in a couple weeks to add some high hats in my living room.
