Originally, I asked for a scored, colored, concrete slab for my rear patio. When Chris Roberts? team installed it, they tore out the existing wood deck and discovered concrete under the old wood deck. They then poured the new concrete over existing concrete, and when complete, the new concrete slab was above the level of the house foundation. This caused water to leak into the family room of my home and to damage the wood siding on the outside wall. Thus, Chris Roberts had to tear out the whole thing (at their expense). At that time, they discovered that the old concrete (which was under the old wood deck) was part of the house slab with post-tension cables running through it and back under the house. Thus, they had only a few choices: 1) Tear out the old concrete (which was part of the house foundation); 2) Pour concrete on the lower part of the patio (to which the concrete foundation did not extend) and install flagstone over both the new concrete (at the lower end of the patio) plus over the existing foundation slab; 3) Refund my money and walk away from the job. To Chris? credit, he chose option 2 and installed beautiful flagstone. He kept telling me how much more expensive flagstone is versus a concrete slab (which is what I paid him to install). However, he never did anything to pull the water (when it rains) away from the patio. The first time we had a heavy rain, the patio collected several inches of water and started backing up towards the house (even though the patio flagstone was graded away from the house). After entering a negative review on Angie?s List, and asking them to intervene, I received a call from Chris. He volunteered to grade the dirt (where my yard and patio meet) so that water will not collect there, and to install a 9-inch grate at the end of my patio plus underground pipe to funnel the water to the front of my house. He did this for free in order to maintain a good rating on Angie?s List. Bottom Line: Chris demonstrated integrity by making everything right. I just wish that the work had been done properly the first time.
