Swimming Pool Contractors in California

CSLB's C-53 Swimming Pool classification covers constructing swimming pools, spas and hot tubs, including installing solar heating equipment. Pool builders often install heaters as part of a new pool or remodel. Ask each contractor whether they install the heater type you want.

Why choose this

  • Can build or remodel a pool and install a heater as part of the job.
  • The C-53 classification includes installing solar heating equipment.
  • One contractor can plan the equipment pad, plumbing and heater together.

Things to consider

  • Pool builders may book out far ahead; heater-only jobs may wait.
  • Some builders subcontract heater installs; ask who will do the work.
  • Gas and electrical connections may need other licensed trades.

Questions to ask

  • The contractor's CSLB license number, so you can confirm it on CSLB's Instant License Check.
  • Who pulls the permit (and any separate electrical, plumbing or gas permit) and whether permit fees are included.
  • The heater make, model and output, and how they sized it for your pool. Ask them to show the calculation.
  • Warranty terms: manufacturer warranty on the equipment and the contractor's own warranty on labor.
  • Whether the heater is included in a new pool or remodel quote, or priced separately.
  • Equipment pad location, and clearances for a heat pump's airflow or a gas heater's venting.
