Wish I could give 6 stars

Rick must be part of Black Diamond's A+ Team. He was very competent and hard-working and did a fantastic job, in spite of less than ideal weather. He also helped me with a project I was personally doing (the reason for the electrical outlets being installed near the front driveway gate 500' from the house) and worked with me on this along with providing valuable advice and insight on my project. On top of all that, he was very personable and friendly and a pleasure to be around! He must be Black Diamond's best!

Great apprentice!

Ruger was here to help with the installation of a trenched electric for 2 outlets to be installed on the front fence. He did an excellent job of filling in and mounding up the dirt over the trench made by the DitchWitch. Its a thankless job for a 500' trench, so I am saying thanks. He also helped the electrician in charge of the project and made a very long and involved project not-so-long.

Installation of an Emergency Generator

Great installation of a great generator, followed with good verbal instructions on the operation and features at the end of the project. I am very comfortable with the quality of workmanship, the personability of the employees, and their efforts to minimize any messes the job may create, especially if inside the house. I use Black Diamond now for all my electrical, plumbing, and HVAC needs. They may be a little pricey, but they are worth it, and they get to my projects very quickly with no long waits, so they are very convenient.

Underground Electrical Service to a Barn

In spite of inclement weather, the trench creation, conduit laying and electrical connections were done very well. What was poorly done was backfilling the trench with about 15% of the dirt not pulled back into the trench. It not only left a terrible muddy yard mess in a high traffic area, but it would have left a serious rut when the dirt settled. Admittedly, by the end of the work it was getting dark and the weather worsening, but it was a hasty and messy backfill job that neutralized the good feelings about the electrical work. I approved the work after dark without having seen the poor trench backfill job, but the next morning's light revealed the mess. I complained in an email to Black Diamond, and when the came out for another project two days later (I use the a lot for all my plumbing, electrical and HVAC needs since they usually do very good work) and dressed up the poor trenching job to almost as good as I would have done. After the remedial work on the trench, I would rate them an A-. Before the remedial work it was a gracious D-.

Great service. Awesome commpany!

I have had work done by Black Diamond on four different occasions covering plumbing, electrical and HVAC. They are always very professional and honest about what work needs to be done, the work is of the highest quality and they leave the work area spotless! I will continue to call them for any issues i have with my home. Most recently, they replaced my furnace and David and Rodolfo did a FANTASTIC job! Thanks again Black Diamond!
