Pool Engineering Firms
Decision Tool

The Firm Screen — Every Firm Gets Weighed

Every pool firm arrives holding a gallery. Run its structure through these five requests before you sign: the honest verdict each produces, and what to do with the firms that pass.

The requestHow it runs — and what it decides
"Name the principal who stands behind your seal in my state — name and number, in writing."The principal test — the structure test. Then five minutes on the board's own lookup: active, in-discipline, the name matching the name you were given. A name produced as routine passes the cheapest test in the purchase. A name deferred, approximated, or replaced with project photography has failed it in public.
"Show me your structure — principals, staff engineers, EITs — and who carries my project when the principal cannot."The bench test. Names and roles, in writing, with a named answer to the absence question. 'Our team handles it' from a structure of one is the market's most common depth claim, and this test is its whole cure.
"When do you require the geotechnical report, and how does it change the design?"The soil test. A standard practice stated as procedure — required, read, designed from — with the design decisions it drives named. Soil treated as the excavator's department has failed the test the ground will re-administer at excavation prices.
"Show me one finished job's correction cycle at a counter like mine, in documents."The turnaround test. Comments logged, a written response, revision-identified resubmittal sheets. A cycle that can be produced was a system. A cycle described only in adjectives was a person doing their best, which is not a structure you can schedule against.
"What file will I hold when the job is done — show me its index from a finished project."The paper test — the one about the next thirty years. Calculations, sealed sets as issued, comment responses, approvals, equipment documentation, in one index the owner keeps. An honest firm shows the index the way it shows a drawing: because it manufactures the file on purpose.

Then, the Doors

Whichever firms survive the five requests, the last step is the same: compare them against the published methodology — and start with the evaluated firms whose answers to these requests are stated on this site, screen by screen: the five evaluated firms.

Who Publishes This Directory

Published by Apex Grid Engineering PLLC. The firms evaluated and listed on this site today are the publisher's own family of brands — this is an affiliated directory, not a neutral referee. The methodology below is the standard any engineering firm can be measured against, and it is the standard we hold our own firms to in public. Presentation order on this site is the publisher's choice and an experiment in what helps buyers decide — it is not an objective quality verdict, and no firm pays for placement. Coverage claims are limited to licensure the operator's bench actually holds, stated per state. No reviews, ratings, or project claims are published for any firm unless they can be documented — this site screens the documented structure behind pool engineering firms and publishes the publisher's methodology assessments; it does not publish customer reviews, and you will find none invented here.

Operated by Apex Grid Engineering PLLC. Founder & CEO: Jeremy “Chico” Mills — serial entrepreneur and USAF veteran. Jeremy is the founder and chief executive; he is not a licensed professional engineer, and no page on this site implies otherwise. The engineering behind the listed firms is performed and sealed by their licensed PE benches.
