This contractor installed a concrete deck around my pool with such negligence and incompetence that the only fix, per the engineer I hired to assess the situation and develop a remedy plan (and per half a dozen other contractors called in to propose a solution) was a complete demo and removal. (Too thin, with steep pitch INTO pool, highly uneven/non-level surface, no drainage, improper expansion joints, poured too dry so that there were gaps in the thickness, inadequately reinforced, not floated. Contractors insurer, after inspection, declined to cover, claiming that this was a case of shoddy workmanship for which they bore no responsibility.) Contractor then disappeared, after having begged for a significant advance for materials and to cover cash-flow problems, leaving other tasks unfinished. He repeatedly promised to fulfill his contractual obligations by at least finishing the tasks for which he had been paid, but although he finally removed a pile of construction debris next to my driveway after a year, he has not completed his other tasks nor removed piles of concrete slag he had dumped next to the driveway. Nor did he fulfill promises to at least demo and remove his botched concrete slab.
