Copperline Pools · Estate & heritage shells · Aldermoor & the Copperline valley · Since 1968

We will bore your soil before we draw a shape, publish the shell’s cure on the county record, and build nothing we would not leave to our own grandchildren.
— the three lines every Copperline client signs, and the standard two hundred and forty shells have been held to since 1968

What the three lines mean

The creed, in five lines

A pool that outlives its builder is not a bigger pool; it is a differently-made one. Soil before shape, steel before schedule, cure before finish, hand-setting before speed, and a ledger that tells the next owner exactly what is in the ground. The valley has been handing us back 1970s shells to survey for thirty years, and every one that passes makes the argument again.

1

Soil first

Borings before drawings: the valley’s springs, clay lenses and ledges decide the shell long before the pencil does.

2

The shell is the structure

Engineered steel to the soils report, shotcrete at spec — no value-engineered walls on a pool meant to meet grandchildren.

3

Cure on the record

Twenty-eight days, hosed and covered, witnessed and dated on the county record. The finish goes into a shell that has finished becoming one.

4

Hand-set finishes

Coping set by masons, glass tile set by hand, pebble exposed by craft — the last thing built is the only thing seen.

5

The ledger passes down

Borings, steel, hydraulic math, cure dates, warranties — bound, and handed over with the deed, not lost with the builder.

2025 — 2026 & earlier

Shells, aged on purpose

Six from the Copperline file — two new commissions, four re-photographed for this year’s ledger update at age twenty and well past it. The valley is generous with old shells; we are choosy about which ones we put on the page, because a heritage claim is only as good as its oldest photograph.

How it goes

Borings to first generation

The same sequence on every job — the only variable is your project.

  1. Weeks 1–2

    Borings & the family brief

    The soils rig, the spring map, and a long conversation about who will swim here in 2060. Estate pools are drawn for the third owner, not the first — the brief asks about grandchildren we have not met yet.

  2. Weeks 3–6

    Drawings & the county record

    Engineered drawings, the steel schedule derived from the borings, heritage consents where the garden is listed. The cure dates enter the county record here, before excavation — the sequence is public before it starts.

  3. Weeks 7–16

    Shell, tank & the witnessed cure

    Excavation to the soils report, steel to the schedule, shotcrete for shell and surge tank in one sequence — then the twenty-eight-day cure, hosed and covered, witnessed and dated. On a Copperline shell the cure is not downtime; it is the product.

  4. Generations after

    Finishes, ledger, the handover

    Hand-set coping and waterline, the interior from the register, the first fill balanced — and the ledger bound: every boring, every date, every number the next owner will ever need. It passes with the deed.

The soil report is the first drawing

No shape is pencilled until the rig has been out. Two of the valley’s prettiest concepts died in the borings — one on a spring, one on clay — and both owners got the honest verdict while it was still cheap.

The cure, witnessed

Twenty-eight days on the county record, hosed and covered, dated and countersigned. A green shell is how finishes craze and warranties void; ours finish becoming structures before anything decorative meets them.

The ledger travels with the deed

Borings, steel schedule, hydraulic math, cure dates, warranty language — bound, and handed to whoever owns the house next. A pool you can audit is a pool you can sell honestly.

Fair questions

Questions the vow invites

A published cure date makes people curious, and a ledger you can inherit makes them reach for the surveyor. Good — the valley line answers seven to five, Aldermoor time, and the survey table is out front where the ledgers live.

Why does 1968 matter to a pool I build now?

Because it is evidence, not nostalgia. Two hundred and forty shells across three owners and two springs of valley geology tell us what the first decade cannot: which soils moved, which steels held, which finishes read true at thirty. The ledgers from 1968 onwards are the dataset our rate card and our vows are written from — and they are open on the survey table for anyone who asks.

Can an estate pool take a vanishing edge?

Where the grade and the borings agree, magnificently — and the tank is the honest half of the answer. Every Copperline edge is backed by surge capacity at one and a half times its weir load, in writing, because an edge that flickers at a garden party was under-tanked at design, not unlucky at dusk. The Weir Farm commission on this page carries its tank in the slope, logged in the ledger.

Pebble or plaster for a century pool?

The register’s answer, not a preference: pebble. Exposed aggregate carries a twenty-year expectation in valley water and stays indifferent to the chemistry that stains plaster — and on a shell built for grandchildren, refinishing once in a lifetime instead of three times is the difference between a legacy and a schedule. Plaster remains available, honest, brighter and cheaper, with its chapter handed over first.

What exactly is the ledger?

One bound book per pool: the borings, the steel schedule, the hydraulic math, every cure date, the finish warranty and its expected life, the county record references. It is written as we build, handed over at the fill, and meant to pass with the deed — the next owner, or the next surveyor, audits us from it in an afternoon. Houses have sold on it.

Can you restore our 1958 pool?

Start with the survey — shell thickness, rebar cover, the plumbing as-built — and take the honest verdict with it. The orchard pool on this page was a 1971 shell we condemned in writing and rebuilt in 2025; others have passed the survey at sixty and taken a refinish and a new plant instead. Restoration here means evidence first, romance second.

Word of mouth

The valley, three generations deep

The ledger sold the house. Our buyers’ surveyor spent forty minutes with it and wrote the pool into the valuation as an asset instead of a liability — borings, steel, cure dates, all of it legible to a man who had never seen a pool documented like a bridge. We commissioned our own Copperline the following spring, for the same reason in reverse.
A. & C. Wren-Harcourt · Estate shell, Aldermoor House
They condemned our 1971 pool in writing, with the shell measurements on the page, when two other firms had quoted it a paint job and a prayer. The rebuild ran to the published cure dates to the day. What the family swims in now is the third pool on this property and the first one anyone has ever held records for.
The Ostrander estate · Survey & rebuild, the orchard pool
Our pool is older than our marriage, and both are in the ledger — that is a joke they made first, which tells you something. The edge has not flickered once in nine years of garden parties, the level log is genuinely boring, and when we retile the waterline it will be the same mason’s apprentice, now a mason, who set it.
