Pool checklists

Barrier audit. Walk the perimeter with a tape measure. Barrier at least 48 inches above grade on the outside face. No more than 4 inches of clearance beneath (2 inches over grass or gravel, 1 inch for removable mesh). No opening that passes a 4-inch sphere. Vertical members no more than 1¾ inches apart where horizontals are under 45 inches apart. Nothing next to the fence a child could climb. Gate opens away from the pool, self-closes, self-latches, with the release at least 3 inches below the top on the pool side and no opening over ½ inch within 18 inches of it.

Monthly check. Open the gate fully and let go — does it close and latch every time, from every position? Test each door alarm. Check the cover mechanism and keep its controls out of children's reach. Confirm rescue equipment and a phone are at poolside, as CPSC recommends.

Pre-contract check. Three itemized bids on the same scope. License verified with the issuing agency. Proof of insurance. Payment tied to inspected milestones. Permit responsibility named in writing — Thursday Pools puts pool permits at $100–$1,000 or more, so it matters whether that is included. Barrier supply and installation named in writing. Written warranty documents in hand, read, before signing.

How to choose

Do the barrier audit before the first swim, not after

The pool becomes a hazard the moment it holds water, which is often before the fence is finished.

Put the monthly safety check on a calendar

Self-closing hinges and latches fail gradually. A recurring reminder catches it; good intentions do not.

Never sign a contract you have not read the warranty for

Ask for the actual warranty documents. A salesperson's description of coverage is not coverage.

Check the license with the agency, not the contractor

Licensing is state and sometimes locally administered. Verify the number directly with the issuing body.

Keep a folder of permits and inspection sign-offs

You will need it at resale, and possibly at insurance renewal.
