They arrived on time and started right into the work. However they were very sloppy with all the items ie. leaving the items that were going to be put back on the pool in the mud, upon opening the filter, draining it along with sand right on the spot leaving sand all over the the place( on pump and plugs). They seemed to be in too much of a hurry to get the job done and get out of there. Also when hard plumbing the lines they left a mess of blue stuff (Pipe Cleaner?) all over including on the filter and pad. There is also that blue stuff on the hose bib on the house. Overall I would NOT recommend them to do any job!
