Is DIY pool maintenance actually cheaper?
On paper, yes — DIY saves roughly $50–$90 per month. In practice the gap narrows because retail chemical pricing is higher per gallon, and a single green-pool recovery or burnt-out pump erases a year of savings.
Professional pricing includes bulk chemical cost, equipment, transport, and labor. When a homeowner buys 10% liquid chlorine at retail, pays for reagents, and replaces a brush and vacuum head every couple of seasons, the real DIY number lands closer to $95–$130 per month.
The bigger variable is failure cost. A clogged filter run for months raises pump amp draw and can shorten motor life by years — a $1,100–$1,900 replacement instead of a $150 filter clean.
