A fibreglass overlay costs **$5,000 to $12,000** for a typical residential pool, or $5.85 to $14.04 per square foot across 855 square feet, and it is rated for 10 to 15 years. That works out to $333 to $1,200 per year. The reviews of the category are unusually consistent once you separate the product from the preparation, which is where most of the complaints actually point.

This guide is independent and does not install or sell pool finishes. It does not run laboratory tests and does not publish scores. What it does is read the owner record for the failure patterns that repeat, and explain what each one indicates.

## What the review record covers

An overlay is a glass-reinforced plastic coating applied over an existing pool shell, usually in several coats with a gelcoat finish on top. The pool is drained, the surface is prepared, the layers go on, and the pool is refilled after a cure.

Reviews therefore cover three things: the price, the surface feel and appearance, and how the coating held up. The third is where the detail lives, and it is almost always a story about preparation.

## The price you should see

| Route | Cost | Per square foot at 855 sq ft |
|---|---|---|
| Overlay, small pool | $5,000 | $5.85 |
| Overlay, typical pool | $8,000 | $9.36 |
| Overlay, large or complex | $12,000 | $14.04 |
| Full shell replacement | Usually above $12,000 | Priced separately |

The per-square-foot figures are division: $5,000 ÷ 855 = $5.85 and $12,000 ÷ 855 = $14.04. A quote far below $5,000 is usually a patch-and-coat rather than a full overlay, and a quote above $12,000 is usually bundling tile, coping, or shell repair.

Use the band to calibrate the review. A complaint that a $4,000 overlay failed is a complaint about a job that was not a full overlay, and the review rarely says so.

## What owners praise

The recurring positives are the surface and the maintenance. Fibreglass is smooth, non-porous compared with plaster, and does not chalk in the way a cement finish does. Owners report that the pool feels better underfoot and that the waterline is easier to keep clean.

They also report that the colour holds. A gelcoat finish does not need the acid washing that plaster does to remove scale and metal staining, and it does not go patchy in the same way.

The third positive is speed. An overlay can be finished and refilled faster than a full chip-out and replaster, which matters when the pool is out of service.

## What owners complain about

| Complaint | Likely cause | Product fault? |
|---|---|---|
| Blisters at the waterline | Moisture under the coating | Preparation |
| Chalking or dulling in 3 years | Thin gelcoat, UV exposure | Application |
| Peeling at the steps | Substrate not keyed | Preparation |
| Cracks following shell cracks | Shell movement not addressed | Diagnosis |
| Fading | Pigment choice, sun exposure | Partly |
| Slippery steps | Smooth finish, no texture | Design |

Four of the six rows are preparation or diagnosis failures. That is the most useful thing the review record tells a buyer: the coating is not the variable, the surface under it is.

## How to read a fibreglass review

1. Find the price paid. Below $5,000 is not a full overlay.
2. Find what preparation was included: drain, wash, grind, crack repair.
3. Find the number of coats and the cure time before filling.
4. Find the time elapsed. One season is an unboxing; five years is evidence.
5. Find whether the shell had known cracks or delamination.
6. Look for a follow-up edit after two or three years.

Step six is the most valuable. Owners who return to update a review are the closest thing the category has to a long-term test.

## What the price per year actually compares

The per-year figure is the installed cost divided by the expected life. At the low end, $5,000 ÷ 15 = $333. At the high end, $12,000 ÷ 10 = $1,200.

That range overlaps white plaster almost exactly: plaster runs $333 to $1,429 per year, because it costs less and lasts less. The practical difference is not the money. It is that fibreglass buys three more years between jobs and a smoother surface, and plaster buys easier patching and a lower entry price. For an owner who intends to keep the pool for one cycle, the two are close to a wash.

## Where fibreglass suits, and where it does not

Fibreglass suits a sound shell, a smooth finish preference, and an owner who wants a surface that is easy to keep clean. It suits pools that are resurfaced on a 10-to-15-year cycle and where the water chemistry is kept in range.

It does not suit a shell with active delamination, because the coating fails with the substrate. It does not suit a pool that is used with heavy abrasion, because the gelcoat is thin. And it does not suit an owner who wants a troweled, textured finish.

## The short version

The fibreglass review record is a record of preparation. At $5,000 to $12,000 for 10 to 15 years, the surface is a reasonable buy on a sound shell and a bad one over a failing substrate. Read the price, the prep, and the elapsed time, in that order.
