Pool Repair

Signs Your Pool Needs Repair

Pool repair for gunite and plaster pools covers cracks, structural and surface damage, and failing parts such as lights, pumps and equipment. In Phoenix, Mesa and Chandler, many pools sit behind homes built around 1985. Aging plaster and equipment are common repair triggers.

Watch for these:

• Cracks. Hairline cracks and structural cracks are different problems. See causes of pool cracks and when to repair.
• Failing components. A dead or flickering light, a noisy pump, or equipment that won't run. The bulb guide shows where safe DIY stops.
• Surface damage. Rough, flaking or stained plaster, or water loss you can't explain. See why a pool loses water.

Pump failures tend to peak June through August, when Phoenix highs average about 106°F and electrical loads climb.

Sound familiar? A hairline crack, a light that flickers. You ignored it through the summer. Now the damage has spread and the repair is bigger.

Waiting rarely shrinks a repair.

Stop and call a pro for anything involving electrical circuits, gas or structure.

What Pool Repair Costs: The Short Version

Price depends on the type of damage, access, parts, and whether electrical work is involved. In Phoenix, caliche hardpan can sit just 1 to 6 feet down, which makes access a real cost driver for structural or plumbing repairs. A light job shows how wiring and electrical safety change the bill: see how much pool light replacement costs.

The figures below come from Phoenix-area pool companies' own websites, checked October 2026. They are general guidance, not quotes.

That $100 to $20,000 spread is the point: a small fix and a major one share a name.

How a Pool Repair Job Works, Step by Step

A pool repair job runs in six steps, summarised here and detailed below.

Step by step

How a pool repair job runs

1. 1

   Inspection

   The contractor finds the cause, not just the symptom.

2. 2

   Quote

   You get a written contract with the license number and price.

3. 3

   Permit check

   The contract names who pulls any permits.

4. 4

   Repair

   Work proceeds within the license class.

5. 5

   Testing

   Pumps, lights and circulation are run before sign-off.

6. 6

   Handover

   You get the final paperwork and an account of the work.

1. Inspection and diagnosis. The contractor finds the cause, not just the symptom.
2. Written quote and contract. A contract over $1,000 must be in writing and include the license number, price, payment terms and the ROC complaint notice.
3. Permit check. Permits are the owner's responsibility unless the contract says otherwise, so the contract should name who pulls them. Repair-size permit thresholds in Phoenix, Mesa and Scottsdale vary; confirm with your city's permit office.
4. Repair. Work proceeds within the license class.
5. Testing. Pumps, lights and circulation are run before sign-off.
6. Handover. You get the final paperwork and a clear account of what was done.

City offices check licensing in different ways. Mesa asks for a Contractor Licensure Verification Form on pool permits, and Scottsdale's application asks for the ROC number.

If a repair touches the barrier, a new permit is required to alter or repair an approved pool barrier. The barrier must be at least five feet high, with no opening a four-inch ball can pass through.^[2]

Pool sweeper and liner repair: where they fit

Pool sweeper repair is usually a component or equipment job. Liner repair applies to vinyl-lined pools, not gunite.

How to Verify an Arizona ROC Pool License

Arizona requires an ROC license for pool repair. R-6 covers service and minor repair of residential pools, but excludes gas lines, potable-water plumbing connections, and electrical work beyond the first disconnect. B-5 covers broader construction and repair, plus code-required pool barriers.^[1]

Before you hire in Scottsdale, Gilbert or Tempe:

• Search the ROC Contractor Search.
• Confirm the license is active and the class covers your job.
• Check bond and Recovery Fund status.
• Never pay cash, and don't let payments run ahead of the work.

"Licensed, bonded and insured" proves nothing on its own.

Checklist

Verify before you hire

0 of 5 ticked

• Is the license active on the ROC Contractor Search?
• Does the license class cover your job (R-6, CR-6, B-5, B-6, KA-5 or KA-6)?
• Is the bond and Recovery Fund status in good standing?
• Does the job need gas lines, potable-water plumbing or electrical work beyond the first disconnect?
• Are payments tied to completed work, with no cash?

Tick them off as you go. Nothing is saved or sent.

The ROC requires workers' compensation, not general liability. The complaint window is two years, and owners who hire unlicensed entities have no ROC recourse.

Pentair, Hayward and PHTA credentials are optional extras, not licenses. For help comparing, see questions to ask before hiring and which license fits your job, then compare the pros listed below.
