Fathom Poolworks · The build vow · Wren Harbor & the Gullrock shore · Since 2006
We will hand you the turnover math before the contract, publish the fill date inside it, and finish your pool with the same crew that dug it.
What the vow means
The creed, in five lines
Turnover math — your gallons divided by your flow, the hours the whole body takes to pass the filter — sits on the cover of every Fathom build book, because water that does not move is a chemistry bill pretending to be a pool. The rest of the creed is plumbing honesty and a calendar with a spine.
Math before contracts
The turnover figure, the pump curve and the filter area printed on one sheet — before any money moves.
The fill date, published
A dated dig-to-fill sequence inside the contract, not a shrug at week nine.
One crew, dig to fill
The crew that shoots the shell is the crew that sets the tile. Nobody hands your yard to strangers.
The finish, named
Pebble or plaster, texture and expected life, in writing at signing — never chosen from a truck.
The school, before the swim
An hour with the water book and the controller before the first splash, so the pool is understood, not just delivered.
Services & rates
The vow, priced
Vow prices are from last season’s Gullrock builds and cover excavation through first fill on a straightforward lot; rock, seawalls and spillovers are priced at the free yard walk, not discovered on dig day. Every line carries the same three sentences from the top of this page — the vow is not an upgrade tier.
Gunite pool, the full vowfrom $93,000
Shell, 28-day cure, turnover math on the build-book cover, interior of your register, fill date in the contract
Vinyl pool, the full vowfrom $57,500
Panel walls, measured liner, same hydraulics rule, same published fill date
Spa or cold plungefrom $19,800
Therapy seating sized to the people using it, gas or heat-pump, jet count from your shoulders not a brochure
Exposure upgrade to pebble$9,200 typical
The twenty-year interior over the standard quartz, priced at signing if the budget means it
The hydraulic retrofitfrom $6,400
For a pool that fights its own water: turnover audit, returns re-aimed, pump right-sized, sheet reprinted
The water schoolincluded
Chemistry, controller and the first season, taught at your pool with the book left behind
The math travels
The turnover sheet is printed on the build-book cover and yours to keep. Any service company in the county can check our work with it — which is exactly why we print it.
The fill date has teeth
Ten working days past the published date for reasons that are ours, and the contract credits $120 a day. It has paid out once since 2006, and that pool is on this page under a new vow.
The crew has one name
Fathom runs two crews and no subcontractor roulette. The people who dig your pool are the people who hand you the water book at the school.
How it goes
The vow weeks
The same sequence on every job — the only variable is your project.
Week 0
The yard walk & the math
We walk the lot, read the gallons the shape would hold, and print the turnover sheet the same evening — pool, pump, filter, hours per pass. If the shape you want moves water badly, you hear it at this table, with the arithmetic beside it.
Weeks 1–3
Design, permits, the date
The drawing, the interior chosen from samples with texture underfoot, the county filings — and the contract that carries the fill date, the finish and the vow, all on one page you can read in a chair.
Weeks 4–9
Dig, shell, the cure
One crew, start to finish: excavation, steel, shotcrete, then the 28-day cure with the hose and cover on it. The cure is in the published sequence from day one — nobody discovers it at week eight.
Weeks 10–12
Finish, fill & the school
Interior in, waterline set dead level, balanced fill — then the hour of school: chemistry, controller, the log, the book left on your counter. The vow ends when you understand the pool, not when the hose comes off.
2025 — 2026, the shore
Pools under vow
Six from last season, photographed the week of the school. The build book — turnover sheet on the cover, fill date inside — goes with the pool wherever it is photographed.
Fair questions
Questions the vow invites
A published fill date makes people curious; the turnover math makes them reach for a calculator. Good — the harbor line answers seven to five.
Why put the turnover math on the cover?
Because it is the one number that predicts whether a pool behaves. Gallons divided by flow — hours per pass — decides how hard the sanitizer works, how the heater holds, how the water reads. Printing it before the contract means the plumbing was designed, not hoped for, and it gives you a number any honest service tech can audit us against.
What happens if you miss the fill date?
The contract credits $120 a day past ten working days, when the delay is ours. It has paid out exactly once since 2006 — a September the county concrete plant closed — and that client’s replacement pool was built under the same vow without our asking twice.
One crew really means one crew?
Two crews, no subs, and the crew you meet at the yard walk is the crew at the tile. The trade’s disappearing act happens between companies handing yards to strangers; we kept the crews and lost the subcontractors, and the vow is cheaper to keep that way.
Pebble or plaster at Fathom?
Named at signing, priced at signing, chosen with samples under your bare foot. Pebble for the twenty-year family pool, quartz where the budget sits, plaster for brightness at the least cost — every choice carries its expected life in the contract, and the school teaches you what your finish will do in year three.
What is the water school?
One unhurried hour at your own pool before the first swim: the test kit done by your hands, the controller walked through, the log opened, the book left on the counter. The vow’s last line. Pools fail in the hands of people who were handed keys instead of understanding — so we do not hand over keys.
We had a builder vanish on us once — nine weeks of silence and a hole in the yard. Fathom’s contract had a fill date in it, the crew chief’s name on every week of the schedule, and the turnover math printed where the salesman’s logo usually goes. They filled on the Thursday the contract named. I have never known a Thursday so satisfying.
