Master Concrete & Interlocking

Last year in March 2014 We planned to have our front porch with stairs, side walk, garden wall, back patio with stairs in stammped concrete. We called Master Concrete and the sales person Tiago visited our house to provide us the quote for the work. He was very nice and helped us in finalizing the design (he did excellent job as sales person). We gave him advance deposit and waited for our work to start. The work started in June and we had lot of problems since then. There was miscommunication between my written drawing and agreement versus what the head "Herculano" was making. Fortunately my wife was at home and she told him that it does not look right! Herculano tried to ignore her, but then she called office again and insisted to talk to Tiago. After lot of frustration the matter was resolved and they made what was on the agreed drawing. We paid full amount as soon as the concrete work was complete but the sealant was supposed to be done after few weeks. We had to call many times for that as well, and the sealant work done was done in so much rush that in many places you can see the marks like work done by non professional person.
The overall work quality was so so, not very impressive and when we mention about the quality, Herculano's response was "It is concrete work not wood work", while we could see clear imperfections in the finish. As money was paid in full, not much we could do!!
In less than 8 months, we started seeing the cracks in the garden wall, many chips all over the surfaces, even a big piece broke out from the side walk concrete. I emailed and sent pictures to the office on April 11, 2015 for the repair work as it is still in the warranty. I have called many times, and only one time I was able to get the real person to response and I was told it will be repaired in May, it is almost end of May and I have not seen any action from MC to fix it. I have sent another email reminder and if they come and fix the problem and satisfy us, I will come back and update this review. As it is today, I can not recommend MC to any one.
