Amazing Service Experience

After calling several other electricians in the area and being sorely disappointed by their lack of response; I called Haas and Sons Electric. They were amazing. Price quoted is the price that I paid. The work was done in an effective and efficient manner with no mess made. Additionally, they worked with me to make my ideas work, within a budget and without unnecessary mess or damage to my home. Nick was amazing. Personable and friendly; a real asset. I am extremely pleased with their work and the customer service I received. Anyone who lives in Maryland knows customer service is often lacking but, not in this case. I highly recommend Haas and Sons. I will be using them next for some smart switches and replacing my outlets.

We have provided pricing for the necessary aluminum wiring repairs to the home. We found the aluminum wiring present in the bedrooms, all throughout the first floor, with the exception of some kitchen receptacles. Basement has aluminum wiring at all light fixtures and the washer and dryer locations. We recommend that the aluminum wiring be remedied and smoke alarms should be installed.

Install customer supplied ceiling fan Replace plastic box with fan rated box The reason for today’s visit was to look at installing a customer supply ceiling fan and a pre-wired location in the front bedroom on the second floor. The bedroom currently had a surface mounted ceiling light however, when we pull down the light, we noticed that it was a basic plastic old Work box. I informed customer I would have to replace the box to support the weight of the ceiling fan. Customer agreed we went ahead and installed the new fan with the new bar box fan support brace.
