When you’re comparing pool builders, the warranty sheet is one of the few documents that tells you how confident a builder really is in their work. It’s also one of the most misunderstood. Homeowners hear a big number, assume it covers everything, and find out years later that the fine print says otherwise. At Advantage Custom Pools, we’d rather you understand exactly what you’re getting before a single shovel hits the ground.

This guide breaks down the two numbers that matter on an Advantage Structural Foam (EPS) pool — the 2-year pool warranty and the 40+ year waterproofing rating — what each one means, why they’re different, and how to read any structural foam pool warranty (or any pool warranty at all) like a pro.

Two Numbers, Two Different Jobs

The single most common mistake we see is people blending warranty terms together. On our structural foam pools, there are two distinct commitments:

• The pool warranty — 2 years. This is our workmanship and installation coverage. If something we built isn’t performing the way it should during the first two years, we come back and make it right.
• The waterproofing — rated for 40+ years. This is a manufacturer’s performance rating on the waterproofing system that keeps water inside the shell. It describes how long that membrane is engineered to last, not a blanket promise covering every component of your backyard for four decades.

Those are two different numbers doing two different jobs. Any builder who rolls them into one headline like “40-year warranty on everything” is either oversimplifying or hoping you won’t ask. Ask.

What the 2-Year Pool Warranty Covers

The first couple of years after a build are when installation issues show up, if they’re going to show up at all. Soil settles, plumbing sees its first full season of pressure, equipment gets its first Utah winter. That’s exactly the window a workmanship warranty is meant to protect.

Typically covered

• Defects in how the pool was built and installed
• Plumbing connections and fittings installed by the builder
• Issues with the shell assembly and finish application
• Coping and tile installation problems tied to workmanship

Typically not covered

• Damage from improper water chemistry or neglected maintenance
• Freeze damage from an un-winterized system
• Equipment covered separately by its own manufacturer warranty (pumps, heaters, automation)
• Changes, additions, or repairs made by another contractor
• Acts of nature, ground movement beyond normal settling, or physical impact

Your specific contract spells out the exact terms — read it, and ask us to walk through anything that isn’t clear.

What the 40+ Year Waterproofing Rating Means

Waterproofing is the heart of a pool’s lifespan. A shell can be structurally sound and still fail you if water finds its way through it. On a traditional gunite pool, the concrete itself is porous, and its surface finish (plaster, pebble) is what keeps water in. That plaster usually needs resurfacing every 10 to 15 years in Utah — sooner if chemistry isn’t dialed in or freeze-thaw cycles are brutal.

A structural foam pool is built differently. The EPS structure is paired with a dedicated waterproofing system engineered and rated to perform for 40+ years. That rating is why structural foam pools are such a strong long-term value: the component most likely to force an expensive renovation on a concrete pool is designed to outlast the timeline most homeowners will ever own the home.

Important nuance: a performance rating describes how long a system is engineered to last under proper conditions. It assumes balanced water chemistry, proper winterization, and normal use. It’s a measure of durability, not a promise to cover damage from misuse.

Why Structural Foam Holds Up Better in Utah

A warranty is only as good as the construction behind it. Here’s why structural foam tends to generate fewer claims in the first place:

1. It handles freeze-thaw better

Utah swings from triple-digit summers to single-digit winter nights. Rigid concrete shells expand and contract with those swings and can develop hairline cracks over time. EPS foam is a closed-cell material with inherent insulating properties, which moderates temperature swings inside the shell wall.

2. It’s naturally insulated

Because the foam insulates, water holds heat longer. That means lower heating bills, a longer swim season, and less thermal stress on the finish. We covered this in depth in our post on pool insulation — it’s one of the biggest quiet advantages of the system.

3. It works on slopes and tough lots

Many Utah lots — especially along the benches of the Wasatch Front — are sloped or have challenging soil. Structural foam integrates cleanly with retaining walls and is lighter than concrete, which reduces load on hillside sites.

4. The marble-clad finish is built to last

Our pools use a marble-look interior finish that resists the etching and staining that plague lower-end plaster. A durable finish over a long-rated waterproofing system is a combination that simply doesn’t need the constant attention a traditional pool does.

5. Faster, more controlled builds

Structural foam builds typically move faster than traditional gunite, with fewer weather-dependent curing steps. Fewer variables during construction means fewer chances for installation defects — which is exactly what a workmanship warranty exists to catch.

How to Compare Pool Warranties Between Builders

Whether you build with us or someone else, use these questions to cut through the marketing:

• Is this a workmanship warranty, a manufacturer warranty, or a performance rating? They’re not the same thing, and a good builder will explain the difference without hesitation.
• What specifically is covered, and for how long? Get component-by-component answers: shell, waterproofing, finish, plumbing, equipment, coping, decking.
• Is coverage prorated? Some long-term warranties shrink in value each year.
• Is it transferable if you sell the home? This matters for resale value.
• What maintenance is required to keep coverage valid? Most warranties require documented water chemistry and proper winterization.
• Who actually services claims? The builder, the manufacturer, or a third party? And are they still in business?

If a builder answers every question with “it’s all covered,” that’s a red flag, not a selling point.

Protecting Your Coverage: A Simple Owner Checklist

You play a role in keeping your pool — and your warranty — in great shape:

• Keep water chemistry balanced and log your readings (a phone note works)
• Winterize properly before the first hard freeze, usually by late October in most of northern Utah
• Use approved chemicals and cleaning tools on the interior finish
• Call your builder first for any repair during the warranty period
• Keep your contract, warranty documents, and equipment registrations in one place

The Real Value: Fewer Big Bills Down the Road

The honest way to think about warranties is this: the 2-year pool warranty protects you during the period when installation issues surface, and the 40+ year waterproofing rating tells you how long the most failure-prone part of a pool is engineered to last. Together, they point to a pool that should cost far less to own over 20 or 30 years than a traditional shell that needs periodic resurfacing.
