Best Denver Commercial Electrical Contractors in Denver CO

Excellent folks and company! Pleasant to work with; many thanks for all your efforts! Nigel performed a fantastic job with the rewiring and the new lighting fixtures that were installed. Definitely recommended!

These guys go it right. In an age when contractors do shoddy work, late and for premium money, Carl brings it in professionally, on time and on budget with minimal disruption to my business. He built out our 15,000 foot store and just helped us power up a new sign and rearrange our registers. Carlton is top notch!

Cost me 200 dollars to have a switch replaced. My fault for not asking about their pricing before they came out. Took less than 10 minutes. Their minimum service charge is a lot more than other places. A friend of mine recommended them and I figured he wouldnt recommend a place that would rip me off. I was wrong. Called another company (after the fact unfortunately) and their basic service trip charge is 90 dollars. The standard is 90-100 and these crooks charge twice that. Use at your own risk.

JM Electric was just wonderful. I had Hannah come out and she was very knowledgeable, went above and beyond, and I am very satisfied with the work.

Cody came to review my home inspection and to make recommendations for work on the home I just purchased. The work was valuable to my house and made me feel very comfortable that the electric service in this home is up to date and safe.

Daniel came within a couple hours of being called in a stressful situation for me. He was polite, professional and came back in a few weeks to replace my breaker box. On time, communicative and did a great job! Thank you Daniel.

The quality of work that was done was above and beyond my expectations. Areno was quick to diagnose and give and honest quote for the job and did not charge for things that were not needed. Great job! Definately would recommend him to others.
