After years of going through several pool companies who supposedly "claimed" they knew what they were doing when it came to opening, closing and other services such as leak detection, pool covers, heaters, filters, installation of hard covers etc., I've finally found one that ACTUALLY KNOWS what they're doing. Ontario Pool Service where nice enough to come to my home in very cold rainy weather and close my pool. They provided exceptional information about the proper methods of pool closure including, adding a gizmo, anti freeze, replacing aqua lamps, etc. I want to give a special thanks to Vlad and David who also provided me with free algaecide instead of charging me the regular $33 so they could use the bottle as a gizmo for my skimmer basket. If you're like going from pool company to pool company and not being satisfied with the work they do, look no further cause Vlad, David and Stacey are probably the most knowledgeable people when it comes to anything pool related. And trust me, I have an expensive in ground pool 16x32 and I couldn't be more satisfied with the work they've done on it. I'll be sure to call them from now on when it comes to anything pool related. Thanks guys ! Asad from Scarborough.
