Estimate your monthly cost

$300–$500/mo

Based on 1 body of water and medium usage

This is a general estimate from typical industry pricing, not a Guardian quote. Actual cost depends on your pool's actual size, equipment condition, and compliance needs — get a free on-site inspection for a real number.

How this estimate is calculated

This isn't a black box — the estimate is built from four factors, the same ones that actually drive a real quote:

  • Property type sets the base range: a small HOA pool costs less to service than a daily-use hotel pool with a much larger bather load
  • Number of bodies of water adds roughly 30% of the base range per additional pool, spa, or wading pool — each one needs its own chemistry check and cleaning
  • Usage/bather load shifts the estimate up or down — a heavily-used pool needs more frequent attention to stay in DOH-required chemistry range between visits

Why an actual quote can differ from this estimate

Equipment age and condition, how far your chemistry currently is from DOH-required range, whether documentation/compliance work is already in place, and site-specific factors (access, existing equipment brand, current contract terms) all move the real number in ways a four-question calculator can't capture. That's exactly what a free DOH-ready inspection is for — a real walkthrough of your actual pool, not a category-based guess.
