I recently had our sub panel replaced, and Sergei did an outstanding job from start to finish. He was professional, knowledgeable, and took the time to explain the entire process clearly. The work was completed efficiently, neatly, giving me confidence in the safety and reliability of our electrical system.
What stood out most was his attention to detail, punctuality, and respect for our home throughout the project. He made sure everything was properly tested before leaving and cleaned up the work area thoroughly.
I highly recommend him to anyone looking for a skilled and trustworthy electrician. Excellent workmanship and great customer service!

Sergei was very professional and through we had to replace our kitchen lights and he did an excellent job. He make sure everything was perfect before cleaning up. We already have other ideas to use Westpro.
Sergei was professional, punctual and finished the project (installing two new bathroom fans) ahead of schedule. I would hire him again.
