Trustworthy, Communicative, Detailed, and Careful

Nick and Alex were consummate professionals and extremely friendly. They provided us with the technical knowledge about the damage that occurred, what was needed to repair the damage, and identified further work that was needed to make our home code-compliant and to strengthen our protection against power surges--something that a competing electrical company did not do. We felt that they were honest and detailed and that they cared enough about our home to figure out alternatives that would cause the least amount of damage to implement the repair solution.

Expert service in every way

Hello, Mr. Michael Wendler visited my house to install a 20A ground-fault-protected circuit in my garage, as well as a surge-protection system for my entire house. Michael did a wonderful job and was very good at explaining everything he did along the way. I had many questions (I am a retired scientist), and Michael displayed great patience going everything thoughtfully until I had all the information I needed. He is a terrific representative for Haas & Sons, and I am certain you are glad to have him. For future electrical work, I will be calling Haas & Sons and asking for Michael. Thank you, Malcolm Niedner

We will install a new service cable from the meter to a new point of attachment at the peak of the home. We will need to install a new ground and system to port to bring it up to today’s requirements. We will pull an electrical permit and coordinate county inspections as well as the Power company final time. We are unable to open the panel cover at this time without opening up the wall. If when work is being performed and we find damage or anything that needs to be addressed there will be an additional charge for needed work to be performed.

Original call was to check the intermittent power in the kitchen lighting. I noticed improper connections to the switches and receptacles, stab in method was used. When I inspected the panel I found scorched and loose breakers. In addition upon inspection of the meter and main breaker located in the meter stack I found the breaker was damaged and weathered. This breaker at the meter was loosing an entire phase. I recommended that this breaker and the panel as well as the kitchen lighting circuit be restored to new condition. We replaced the breaker at the meter stack (Siemens 100A), the existing panel and replaced all devices on the the lighting circuit for the kitchen ensuring proper terminations.
