Fast, Quality, and Professional

The service was excellent. Alex was professional and curious to my house and myself. The quality of work was top notch. I highly recommend Haas & Sons to anyone needing electrical work done. Personally I will continue to use them for our household needs.

Great Service. Larry was Awesome!!!

Larry at Haas & Sons was tremendous. Took the time to explain everything to me and fixed all of our electrical concerns. I could not have asked for a more professional and positive experience.

Awesome job!

Alex did an awesome job and was honest and helpful the entire time. He was efficient and thorough and cleaned up everything when he was done. I never felt pressured to buy anything and he left all decisions up to us. It has been a long time since I was this satisfied with a contractor. Plus- he loved our dog who was very curious and followed him around the house!
