Pool Renovation Cost Guide

Even the most well-built concrete pools need structural renovations eventually. The plaster finish roughs up, waterline tiles crack, and deck surrounds shift. If you are planning a renovation, here is a breakdown of average restoration costs.

1. Pool Resurfacing (Replastering)

The interior plaster finish is what keeps a concrete pool watertight. Constant contact with sanitized water degrades this plaster layer over **7 to 10 years**.
- **Standard White Plaster:** The most common option. Costs **$5,000 to $8,000** for a medium-sized pool.
- **PebbleTec Finish:** A durable aggregate finish made of tiny rounded pebbles. Lasts 15-20 years. Costs **$9,000 to $15,000**.

2. Replacing Waterline Tiles

Waterline tiles prevent body oils and pollen from staining the pool shell. Over time, freezing temperatures can crack these tiles or cause the grout to crumble.
- **Average Cost:** Retiling a standard 16x32 pool (approximately 96 linear feet of perimeter) costs **$2,500 to $5,000** depending on the tile material (ceramic vs premium glass).

3. Replacing Coping Stones

Coping is the stone or concrete border that caps the pool wall shell, separating it from the deck.
- **Average Cost:** Replacing old brick or concrete coping with fresh safety stones costs **$2,000 to $4,500**.

4. Deck Resurfacing & Overlays

Sun damage and water exposure can stain or crack surrounding concrete decks.
- **Spray-On Acrylic Overlays:** A textured, cooling top layer applied over existing concrete. Costs **$4 to $8 per square foot**.
- **Complete Deck Replacement:** Jackhammering old concrete and pouring new pavers or wood decking costs **$12 to $35 per square foot**.

Combining resurfacing, retiling, and coping repairs into a single project saves you money on draining the pool, prep labor, and contractor mobilization fees.
