Are Concrete Pools Harder to Maintain Than Fiberglass Pools?

FAQ #32: Are Concrete Pools Harder to Maintain Than Fiberglass Pools?

This question gets asked constantly — and the honest answer is:

It depends far more on the interior finish and build quality than on the pool type itself.

The idea that concrete pools are automatically harder to maintain than fiberglass pools is outdated and oversimplified.

Why Concrete Pools Earned This Reputation

Historically, concrete pools were more demanding to maintain because:

Traditional plaster finishes were porous

Algae could embed into the surface

Brushing needed to be more frequent

Water chemistry required tighter control

Resurfacing was inevitable

That reputation was accurate for older finishes — and it still applies to poorly executed concrete pools today.

How Modern Concrete Finishes Change the Equation

With today’s upgraded interior finishes, maintenance expectations for concrete pools look very different.

Modern concrete finishes can offer:

Low-porosity or non-porous surfaces

Strong resistance to algae and staining

Longer surface lifespans

Reduced brushing requirements

More forgiving chemistry than traditional plaster

In some cases, especially with premium or lifetime finishes, maintenance demands can be comparable to fiberglass, provided water chemistry is managed properly.

Where Fiberglass Still Has an Advantage

Fiberglass pools are naturally low-friction to maintain because:

The gel coat surface is smooth and non-porous

Algae adhesion is reduced

Day-to-day brushing is minimal

Chemistry tends to stay stable more easily

For homeowners who want the simplest possible maintenance routine, fiberglass still offers an edge — especially in the early years of ownership.

The Real Difference: Predictability vs. Permanence

A more accurate comparison looks like this:

Fiberglass pools

Very predictable day-to-day maintenance

Minimal brushing

Potential long-term surface aging or re-gel coating

Concrete pools with modern finishes

Slightly more involved chemistry awareness

Highly durable surfaces

Long-term or lifetime finish potential

More customization flexibility

Neither is inherently “hard.”

They simply require different kinds of attention.

Installation Quality Matters More Than Material

A poorly built fiberglass pool will be harder to maintain than a well-built concrete pool — and vice versa.

Maintenance problems usually stem from:

Poor drainage

Inadequate circulation

Cheap or undersized equipment

Improper surface installation

Material choice doesn’t override construction quality.

Owner Habits Matter Too

Regardless of pool type, maintenance effort is influenced by:

Consistency of water chemistry

Seasonal opening and closing practices

Bather load

Local climate

No pool stays easy if it’s neglected.

A Better Question to Ask

Instead of asking:

“Which pool type is harder to maintain?”

A better question is:

“Which pool type and finish match how involved I want to be long-term?”

That framing leads to fewer regrets.

The Bottom Line

Fiberglass pools are generally easier day-to-day, especially early on

Concrete pools with modern upgraded finishes are not inherently harder to maintain

Older or basic concrete finishes still require more effort

Build quality and owner habits matter more than material alone

Concrete pools aren’t harder by default.

They’re just more dependent on doing things right from the start.
