Why pools

Elegant Water Features for Backyard Retreats

Designing and building an outdoor space that features a swimming area requires careful attention to both form and function. DECOMA Industries creates elegant and efficient water features that transform a backyard into a personal retreat, while also considering safety, durability, and aesthetic value. Every project starts with an understanding of the homeowner’s needs and the existing landscape, whether the goal is a family-friendly pool for recreation or a sleek, modern design for entertaining guests. The team ensures that each water feature blends seamlessly with the home’s architecture, creating a space that feels natural, inviting, and luxurious.

Functional, Stylish Pool Design Solutions

Material selection, layout, and advanced systems such as filtration and heating are all carefully planned to optimize the use of the space and ensure longevity. From natural stone features and custom tiles to integrated lighting and water elements, each component is designed to elevate the beauty of the pool area. Additionally, consideration is given to energy-efficient solutions and low-maintenance technologies, allowing homeowners to enjoy their outdoor oasis without excessive upkeep. These projects not only increase the home’s value but also offer a functional space that can be enjoyed year-round, creating a perfect blend of comfort, leisure, and visual appeal.

FAQ

Common questions.

How long does it take to build a new pool?
From design through fill and startup: 4-7 months. Active construction time on-site: 12-16 weeks. The longest variables are permit review (4-8 weeks in most South Bay cities) and weather. Spring and summer are the best windows for new pool construction.
What does a pool cost in the South Bay?
Standard rectangular pool (15x30, plaster finish, basic equipment): $80K-130K. Mid-range with PebbleTec, salt system, integrated spa: $130K-220K. High-end custom (infinity edge, raised wall, water features, hardscape integration): $220K-500K+. Real number depends heavily on yard access and site conditions.
Plaster or PebbleTec finish?
Plaster (white or colored) is the traditional finish — softer feel, lower upfront cost, but needs replacement every 8-12 years. PebbleTec (or Pebble Sheen, Pebble Fina) is the premium finish — pebble-aggregate texture, lasts 15-25 years, costs 30-50% more upfront. Most premium South Bay pools we build today are pebble finish.
Salt water or chlorine?
Salt water systems generate chlorine on-site from dissolved salt — softer feel, easier maintenance, but salt is hard on coping stone and some metal hardware. Chlorine is traditional, lower equipment cost, but requires more frequent chemical management. For oceanfront homes already battling salt air, we usually recommend traditional chlorine.
What about code compliance for safety fencing?
California requires pool barriers (Health & Safety Code 115921-115925) — at least one of: 5-foot fence with self-closing gate, automatic safety cover, removable mesh fence, alarms on every pool-facing door. We design to meet the local enforcement (LA County, Manhattan Beach, Torrance, etc.).
Do you renovate existing pools?
Yes. Replaster, retile, replumb, equipment upgrade. Many pools we work on are from the 1970s-80s and due for a full renovation. We can do a basic replaster (2-3 weeks, $8K-15K) or a full reno (6-10 weeks, $40K-100K+).
