"They are supposed to come tomorrow, they agreed on that. They called and told me that the job is too small and they refused to do the job. Meanwhile I described the job to the woman, the dimensions and the specifics and she agreed but still cancelled it."

"Had a bad experience with this company. Dealt with Harry for the contract and 50% down payment and then was told Joe was doing my project. Oh Joe oh Joe. You can’t make this guy up. The worst case of a pathological liar I’ve ever seen. On the promised day of work nobody would show up. He used every excuse in the book, after about 7 no shows and excuses from worker called out, there is rain in forecast (drizzle at best), the Canadian wild fires, Flu, each time he would sound so genuine, but once the common excuses ran out he would say “I’m coming right now, I’m loading up the bricks in the car as we speak [goes on to tell another worker to load some more bricks in the other truck while I’m on the phone], I cancel my plans and wait… no show. This goes on and on. Then he dumps a pile a of sand on my driveway and that sits for 2 more weeks. Everytime I would call Harry, he would apologize and say I will call him. Was convinced I was scammed with the upfront payment. Threatened to call police on the company. After about 6 weeks past promised day, the work was not very good either. The contract stated polymeric sand would be used to lock pavers. They did not. When I called and showed them pictures they said “oh Joe must have been running low on the polymeric sand, I’ll have him come by tomorrow first thing in the morning and fix that”. I laughed to myself, these guys barely showed up with 50% of payment still with me. How are they showing up after getting paid full. I ended up hiring another company and they locked the pavers and finished the job. If you are not in a rush and don’t care too much about getting the whole work done and good quality, then you can give these guys a try, otherwise don’t be an idiot like me and go read other Yelp reviews."

Qualified, licensed electricians will charge from $50 to $100 per hour. The cost to hire an electrician for emergency visits may range from $100 to $200 per hour because this urgent service usually takes place during off hours and may require an electrician to leave or reschedule jobs they’re currently working on. Scheduling work on holidays or during periods of high customer demand, like after a major storm, will also lead to higher rates or extra fees.
