“Variable-speed pumps are now code-required in California for new pool construction. But the equipment package matters beyond the pump: a good automation controller ($3–5K) lets you control heating, lighting, and water features from your phone. Clients who skip the automation system always add it within 2 years — at 2x the retrofit cost.”
Specify LED pool lights from the start — not incandescent or halogen. LED pool lights consume 65–80% less electricity than incandescent, generate less heat (which affects water chemistry), and last 10–15x longer. The premium over standard incandescent is $300–500 per light. With 2–4 lights in a typical pool, the efficiency ROI is rapid.
Pebble Tec (aggregate) vs Plaster (white/colored): Quick Answer
Choose Pebble Tec for the best balance of durability (15-20 years), texture, and value. Choose plaster for lowest upfront cost. Choose glass tile for luxury visual impact. LA's hard water and year-round sun affect all finishes differently.
| Factor | Pebble Tec (aggregate) | Plaster (white/colored) | Glass Tile (mosaic) |
|---|---|---|---|
| Cost Per Sqft (installed) | $5 – $10 | $4 – $7 | $25 – $75 |
| Lifespan | 15 – 20 years | 5 – 10 years | 20+ years |
| Texture | Textured (pebbled) | Smooth | Smooth (glass) |
| Stain Resistance | Good (pebble hides staining) | Poor (shows scale/stains) | Excellent (non-porous) |
| Chemical Resistance | Good | Moderate (etches with low pH) | Excellent |
| Color Options | 20+ aggregate blends | White + 6-8 colored | Hundreds of mosaic options |
| Hard Water Impact | Moderate (scale in aggregate) | High (visible calcium deposits) | Low (non-porous surface) |
| Best For | Most LA pools, best value | Budget pools, replastering | Luxury, resort-style pools |
LA pool finishes face year-round UV exposure (pools are uncovered most of the year), hard water (170-280 PPM calcium hardness), and Santa Ana wind-blown debris. These factors significantly affect finish lifespan and appearance.
Plaster pools in LA typically last 5-10 years before showing significant scale, etching, and discoloration, especially with hard water. Pebble Tec's aggregate surface hides scale buildup and lasts 15-20 years, making it the most popular choice for LA pools. Glass tile is nearly maintenance-free but costs 4-8x more upfront. NP Line Design builds and refinishes pools throughout LA County and recommends Pebble Tec for most residential pools based on the cost-to-lifespan ratio in our climate.

For a standard 400-sqft pool: plaster $1,600-$2,800, Pebble Tec $2,000-$4,000, glass tile $10,000-$30,000. These prices include draining, prep, finish application, and startup chemicals.
Pebble Tec lasts 15-20 years in LA with proper water chemistry maintenance. LA's hard water can accelerate scale buildup in the aggregate texture, so maintaining calcium hardness at 200-400 PPM is critical.
Plaster is fine for budget-conscious homeowners or rental properties. It costs 20-40% less than Pebble Tec but lasts only 5-10 years in LA's hard water. If you plan to own the pool long-term, Pebble Tec's longer lifespan makes it cheaper over 20 years.
Quality glass tile with proper installation does not crack. Failures come from poor substrate preparation or incorrect thinset. Always use an experienced tile installer. Glass tile is the most durable pool finish available, lasting 20+ years.
Yes. NP Line Design (CSLB #1105249) builds new pools and refinishes existing pools with plaster, Pebble Tec, aggregate, and glass tile throughout Los Angeles County. We also build pool houses and outdoor living spaces. Call (818) 600-7492.
Glass tile is the easiest to maintain because it is non-porous and resists staining, scale, and chemical damage. Pebble Tec is moderate (brush weekly to prevent algae in texture). Plaster requires the most maintenance: frequent brushing, chemical balancing, and acid washing every 3-5 years.
