"Everything looks good after the work was done. I can finally close my bathroom door. I appreciated the fact that the foreman Erick Baez, went over what was done as they were done. I also appreciated that the two installers Manny Erickson and Jesus Villagomez also communicated with me after they were done to reassure that they did a proper job installing the jacks. Very good to know how the process was going. Great job."
