San Marcos shares a border and a water district with our home base in Vista, so a San Marcos pool is one of the easiest for us to keep on a tight weekly schedule. Next Level Pool Service And Repair has serviced pools from Lake San Marcos to San Elijo Hills for more than fifteen years.
You get one technician on the same day every week, a photo report after every visit, and a written diagnosis instead of a sales pitch when something on the pad acts up. Homeowners, HOAs and Cal State San Marcos-area rentals all run on the same routine.

Vallecitos water is the whole story in San Marcos. It's hard, high in calcium, and it scales tile lines and salt cells faster than almost anywhere else in North County. Add the inland heat in Discovery Hills and Twin Oaks, and chlorine demand climbs through the summer. We test six readings on every visit, keep calcium and stabilizer in range so your plaster and equipment last, brush the tile line before scale sets, and log filter pressure and the salt cell every week.
When a pool needs a reverse osmosis treatment instead of another drain-and-refill, we'll tell you, and we'll explain why. San Marcos neighborhoods on our weekly routes include:

Hard water is tough on equipment, so San Marcos pools see more pump, heater and salt cell complaints than most. Before anyone replaces anything, we come out, test the system, and write down what's actually wrong. Most of the time it's scale, a flow restriction, a setting or a clogged basket, and it's fixed during the diagnostic visit.
When it truly needs a C-53 contractor, we say so and refer our licensed partner; we don't sell parts. We also offer:

“I have been through six pool service companies/people in the last 18 months regarding algae growth and spread in my pool… I finally found Next Level Pool Service and he not only told me exactly what caused the problem (over use of stabilized chlorine and shock), but told me exactly how to resolve the current situation and prevent further algae growth.”
