Delcollo does a great job. The techs are polite, friendly, knowledgeable, efficient and clean. They are a dependable, professional service provider, not easy to find these days. I have been using Delcollo for over 40 years.

We've used Delcollo Electric on 2 occasions. Initially to rewire our kitchen and upgrade our main panel when we renovated and on the second occasion when we were having issues with our air conditioning outdoor condenser. The technicians sent were extremely knowledgeable and exceeded our expectations. They are our go-to electricians.

The electricians were great! They worked consistently until the job was fully done! Had a new circuit break box and outside meter replaced and up to code. The men labeled every room to the circuit breaker box. I would highly recommend to everyone! I will be calling again for more electrical work. 100% reliable and professional! Very reasonably priced too. I will definitely be hiring again! Thank you Delcollo Electric!

Delcollo saved my project! Jim Street is the most professional and patient and helpful sales representative / project manager I’ve ever worked with on any project. He answered every one of my questions to assure that the underground service conduit and wire were installed correctly, ensuring a smooth project with Delmarva power for this very time sensitive project. The electricians that came to do the job were professional, polite and patient. Delcollo was very patient with Delmarva’s multiple reschedulings, and also solved the supply chain issue of meter boxes not being available. Jim worked with Delmarva to get my existing meter box approved for the project. Talk about going ABOVE AND BEYOND!

Working with Delcollo was a great experience from scheduling a site visit to obtain an estimate, having the work completed, to invoicing everyone was kind, knowledgeable, and responsive. Tom and Jack showed up on time, were pleasant to have around, and efficient. They worked in multiple rooms of our home installing new wiring, updating switches and installing light fixtures even in some tough spots to access. It looks and functions exactly as we'd wanted. Great experience overall.
