Next Level Concrete Ltd

Hired them to do a stamped slab of concrete around my new solid Ipe deck in Sherwood park. My wife wanted it to look like wood than had been painted. Trevor came over and said he could do it. We gave him pictures and said we wanted at least 5 different colors. He said this was no problem but charged us extra. His quote for the job was $2000-$3000 more than any other contractor but he said he had the skills.
They poured the cement and stamped it to look like barn boards. The stamps didn't line up so there are overlapping lines that ruin the look. The release agent they used was old so it clumped and left black spots that look like oil stains. During the job most of his crew left to do another job. So they were short staffed to do mine. The concrete looked horrible.
He came over and said they would now etch it to bring out the painted board look. I don't believe they have ever done this. They dumped acid on it until it was all just dark coffee brown. Then sealed it in.
I later found out that u need to wait a solid month befor etching and sealing. They did it all in one day. I hate the way it looks. It was supposed to be a piece of art but it looks like I did it myself and cut every corner. Trevor sold his company like they were pros. He's a very good salesman I'll give him that. They job they did is so bad I'm having it removed and re done by pros. It will cost me another $10k to do this. But I hate how it looks that much.
He also promised no damage to my yard. It was a disaster

UPDATE...
March 2018
Received a call from Trevor saying that he had read the negative review and was willing to fix it. Said that they were willing to come and strip, acid etch and re seal the slab. We discussed what we had agreed on originally and he said it was impossible. We had wanted reds, greens, blacks and browns in the cement so that it looked whimsical. Even paid an extra 600$ so they could buy the acid. They showed up with black and brown half used from another job. When i asked about this he said that other colors were impossible. I googled it and lots of companies do colors. I can even go buy the acid myself for $25/color a few kilometers from here. After discussion my wife and we decided to not allow them to come back and attempt to fix it. So much damage was done to our yard and cement that we do not want to risk more damages.
Side note... When I asked Trevor about potential damage to our yard he said there would be none. He stated this several times. Obviously we would have to back fill around the slab, but he said our yard would not be harmed. The wheelbarrows they used left deep ruts and there was lots of spilled cement that killed the grass. Our neighbors had concrete done and the company laid down plywood to roll on. Their grass was fine. My yard was a wreck an it cost us an additional fee to fix it.
This is how i see this job.
We paid twice as much as other contractors quoted and was promised what we asked for. Every corner was cut to save money and hammer the job out. There was no plywood to protect the yard, no money spent to buy the colors we pair for, no planning as to how to pour the slab or stamp it. They didn't even bring road crush. They just used sand i already had in the yard. I asked and he laughed saying that we cant negotiate that after the fact. Makes me angry that were treated like this.

Kudos to Trevor for trying to reach out and fix the damage but we don't need a repeat. Maybe if I spoke to clients that had a good experience but at the time of this review I have not experienced this.
