    Mabda (Ben) is a someone you should avoid at all costs. He charged me $350+HST for fixing a sink at a condo I own. I trusted the work would be done and did not follow up to confirm. Buyer beware, the sink was not fixed at all! If he challenges this review, I have receipts showing what I paid, and pictures that show it was never fixed. Stay away!! The best/funniest part is, he flooded my toilet when he was there too just my luck! Read the reviews and don't waste your time. The good ones are probably fake.

    Cleve and his assistant worked diligently to hardwire two sconces in our bedroom and install extra outlets throughout various rooms in our house. There was a bit of trouble getting the sconces in as we didn't realize that one wall was formerly an outside wall and they had to chip through the brick to create enough space in the wall to fit the back side and wiring of the sconces. We appreciate their perseverance in this regard. Everything is working as hoped and Cleve sent over a plasterer to repair the wall where wires had to be run through our plaster walls. He did a great job; the finish is very smooth. Highly recommend C. Ferguson Electrical!
