Here’s What Our Satisfied Customers Are Saying

Chris Tijerino

We’ve had a wall sconce which has been out for years. After trying several electricians over the years we decided to try Delcollo. They sent out Jackson and Jack to fix the faulty wiring to the fixture. They arrived on time and got straight to work, fixing the issue is a flash. These guys are responsive, courteous, knowledgeable, and very reasonably priced. Delcollo will be my go-to for anything electrical in the future, highly recommended.

Delcollo Electric through its agent Jim was a joy to work with. They did everything they promised to do efficiently and well at a fair price. Jim’s advice was invaluable to us. he specified exactly what we needed to flood our lot with light without overkill, or the added expense that would have brought. We will always now go to this company when we have commercial lighting and other electrical needs.

Florence Duddy

DelCollo service this morning was great! I needed a new smoke alarm installed, so I called at 9:30 am, spoke to Dave, and got scheduled for this Friday 12/5/25. I said he could schedule me any day, no hurry. 20 minutes later, the phone rings, it’s Dave, asking if I would like two of their guys to come today plus they have a smoke alarm in stock if I was interested in that one. The guys showed up at 10:45 am and completed the job, they showed me how the new alarm works, answered my questions, done deal! Thanks to Dave for fitting me in so fast, DelCollo cares about their customers!

Delcollo did a good job with my hot tub power hook up. They were able to accommodate the service within a couple days, and the electrician was on time and courteous. It was good experience and I’d use Delcollo again.

Delcollo recently did electrical work for us. Jerome came out. He was very prompt. He replaced electrical outlets and fixed switches. He was very pleasant and efficient and answered several questions and guided us in our desire to replace some high hats and under counter lights in the kitchen . We have used Delcollo In the past, and have always been very happy with their work and will certainly use them again in the future should the need arise. Would definitely recommend this company.
