Questions to Ask Before Hiring a Pool Contractor

Contractor license status and class for this job

Ask: "What ROC license number and class will cover this exact scope of work?"

Look the number up yourself on the Arizona Registrar of Contractors (ROC) Contractor Search at roc.az.gov. Confirm the license is active, then check that the class matches your job. Make sure the licensed entity named on the record is the one that will do the work.

Pool work falls under several classes, including R-6 and CR-6 for service and repair, and B-5, B-6, KA-5 and KA-6 for broader construction.

The R-6 class has limits. Complete replacement of plaster or pebble interiors and decks, gas lines, and electrical work past the first disconnect fall outside it.

Answer to listen for: a class that fits the job, or a named, licensed subcontractor for the excluded parts. Red flag: a service-class firm quoting a full replaster as its own work. For a deeper breakdown, see R-6, B-5 or KA-5: Which Arizona Pool License Fits Your Job?

Also check the bond and Recovery Fund status on the record. Residential contractors must post a cash deposit or surety bond. They must also either contribute to the Residential Contractors' Recovery Fund or post a second bond.^[1] Is 'Licensed, Bonded and Insured' Enough in Arizona? explains what each credential does and doesn't cover.

Manufacturer programs and industry pathways through the Pool & Hot Tub Alliance (PHTA) show training. They are not licenses.

Required contents of the written pool contract

Ask: "Can you show the full contract before signing anything?"

A verbal quote or a text estimate on a job over $1,000 is a red flag, not a contract. Arizona's contractor licensing law requires a written agreement for a contract above $1,000.^[5]

It should include the contractor's name, address and license number, the owner and jobsite, the date, the estimated completion date, a description of the work, the total price, and the deposit and progress payment schedule. It must also carry the ROC complaint notice in bold type, signed by both parties. You can read the statute at A.R.S. 32-1158 on azleg.gov.^[5]

Go beyond the legal minimum. A pool job lives or dies on scope detail, so ask for:

• Equipment brands and models for the pump, filter, heater and automation
• Materials and finish specifications
• Cleanup responsibilities
• How change orders are priced and approved
• Allowances for rock, caliche, difficult access, drainage or electrical upgrades

Caliche hardpan can sit one to six feet down in the Valley and makes excavation far more expensive than normal soil. If the contract is silent on it, a change order is waiting for you.

Ask for a realistic timeline too, broken into design, permitting, excavation, plumbing, electrical, finish and startup.

Who handles the pool permit under the contract

Ask: "Does the contract name who pulls the permit, and is the fee included?"

ROC states that permits are the owner's responsibility unless the contract says otherwise.^[10] Many contractors include them, but silence in the contract can leave you holding the paperwork. Require the contract to name who pulls them.

Then ask for the permit number or proof of submission. Don't let excavation start on the assumption that permitting is underway.

Cities handle this differently. Mesa lists a Contractor Licensure Verification Form among its pool permit documents.^[6] Scottsdale's application asks for the ROC number,^[7] and pools, spas and fences need separate permits.^[8]

Phoenix reviews pools and barriers. A survey waiver comes into play when the water's edge sits under 5 feet from the property line.^[9] Our Phoenix pool remodel permit guide covers setbacks and survey waivers in more detail.

Whether your specific repair needs a permit is a question for your city's building department. For barrier work, the Arizona pool fence law guide lays out what inspectors look for.

Upfront deposit and progress payment terms

Ask: "What milestone triggers each payment, and what happens if work stops?"

The contract must state the dollar amount of any advance deposit and the stage of construction at which each progress payment falls.^[5]

ROC advises against paying cash and against letting payments get ahead of the work.^[10] If cash does change hands, insist on a signed receipt for the true amount.

Answer to listen for: payments tied to completed stages you can see, such as excavation done, plumbing inspected, finish applied. Red flag: a request for large or final payment while corrective work remains open.

Step by step

Payments tied to visible stages

1. 1

   Excavation done

   Pay only once the dig is complete.

2. 2

   Plumbing inspected

   Release the next payment after inspection.

3. 3

   Finish applied

   Pay for the finish once it is on.

4. 4

   Punch list and cleanup

   Hold back final payment until both are done.

Before final payment, hold back until the punch list is done and cleanup is finished.

Contractor and manufacturer warranties, documented in writing

Ask: "What does your workmanship warranty cover, who honors the equipment warranty, and for how long?"

Treat these as two separate promises. The contractor backs the workmanship. The manufacturer backs the pump, heater or filter, and sometimes only through a registered installer. Get durations and the claims process for both in the contract.

Side by side

Who backs what

Contractor

• Backs the workmanship
• Duration and claims process in the contract

vs

Manufacturer

• Backs the pump, heater or filter
• Sometimes only through a registered installer

A warranty is only as strong as your ability to enforce it. That's why the license check is also a warranty question.

Complaints against licensed contractors must be filed with ROC within two years of occupancy or last work. Eligible homeowners may pursue Recovery Fund payment only after a final court order or final administrative order.^[4] Claims are not guaranteed to be paid.^[1]

Hire an unlicensed operator and none of that applies.

Cancelling a door-to-door pool contract

Ask yourself first: "Did I sign this at my own door because someone knocked?"

For a qualifying home solicitation sale, you may cancel until midnight of the third business day after signing. Cancellation must be in writing, and any clause waiving the right is void.^[2] The required agreement language also says payments must be returned within ten business days after the seller receives your notice.^[3]

Send the notice in a way that gives you proof, and keep a copy. Confirm whether your sale meets the statute's definition by checking A.R.S. 44-5002 or asking ROC.

A "sign today for the low price" pitch is a red flag in its own right.

FAQ: Hiring a pool contractor

What are common red flags when hiring a swimming pool contractor?

No license number, a cash-only request, no written contract, pressure to sign immediately, and a door-to-door low price.

What are important questions to ask a swimming pool contractor?

Start with the license class for your exact job, then the contract contents, permit responsibility, payment milestones, and warranty terms.

What questions should I ask a contractor before hiring them?

The same core set applies to any trade: license and class, written scope and price, permits, payment schedule, warranty, and recent local references.

What are the 3 C's of pool care?

The 3 C's are a pool-care concept (commonly circulation, cleaning and chemistry), not a hiring standard.

How do I check a pool contractor's license in Arizona?

Use the ROC Contractor Search at roc.az.gov. Confirm the license is active, the class fits your work, and the bond and Recovery Fund status look right.

Does a pool contractor in Arizona have to carry liability insurance?

ROC licensing does not make general liability insurance mandatory, so "insured" on a truck proves nothing. Ask for certificates directly.

Which questions apply to my job?

Match the question set to the work. For equipment swaps, such as a pool pump or heater, focus on license class and permits. For a replaster, check that the class covers it. For fence and gate work, ask about barrier code compliance. For a suspected leak, ask who handles any plumbing or electrical portions.
