Guide to Fiberglass Pool Installation

Step-by-Step Guide to Fiberglass Pool Installation: What to Expect from Start to Finish

Deciding to add a swimming pool to your backyard is an exciting milestone for any family. It is the beginning of countless summer afternoons spent splashing with kids, relaxing weekend cookouts with neighbors, and peaceful evening swims under the stars. The journey from a patch of grass to a beautiful oasis might seem like a huge task at first. You likely have plenty of questions about how everything comes together and how long it will take.
At Ocean Blue Pools and Spas, we understand that building a pool is a big commitment. As a family-owned business originally from Ireland and now proudly serving Wilmington, NC since 2009, we know how important your home is to you. We built our lives here because we love the coastal charm and vibrant community, and we bring that same passion for outdoor living to every project we take on. Our goal is to make the entire construction journey as smooth, transparent, and enjoyable as the first time you jump into the water.
This guide will walk you through exactly what to expect when you choose a fiberglass swimming pool. By understanding the timeline and the work involved, you can feel confident and relaxed as your backyard transforms. From the first dig to the final splash, we handle every detail with care. Let us explore the steps involved in bringing your vision to life.

Why Choose a Fiberglass Pool?

Before we look at the construction steps, it helps to know why fiberglass is such a popular choice for families. Fiberglass swimming pools offer the stunning beauty of traditional concrete pools, but they are much more durable and cost less to maintain over time. They are built off-site in a controlled environment, which means they arrive at your home ready to go.
Because we want only the best for our customers, we partner with top manufacturers like Leisure Pools, Aviva Pools, and Tallman Pools. These brands offer everything from classic rectangular shapes to free form designs that mimic natural lagoons. They are proudly made in America and use advanced materials like Kevlar and Carbon Fiber to ensure your pool lasts for decades. If you have been searching online for inground pools near me, you will be thrilled with the quality and variety we bring to your doorstep.

The Pool Installation Process

Installing a fiberglass pool with Ocean Blue Pools and Spas takes about three to six weeks for a standard project. Custom work or changes will add to the timeline, but we always keep you informed every step of the way. Here is a detailed look at how we transform your space.

Design and Planning

Your journey begins with a deep dive into your vision. We listen closely to understand exactly what you want your new backyard to look like. Our team will survey your site, check the ground conditions, and help you select the perfect pool size and shape for your family. We also handle the paperwork, obtaining all the necessary permits so you do not have to worry about local regulations.

Excavation

Once the planning is complete and the permits are approved, the real fun begins. Our skilled crew arrives with heavy machinery to carefully excavate the area where your pool will sit. We dig to the exact dimensions required for your specific fiberglass shell, ensuring the hole is perfectly shaped to support the structure.

Base Preparation

A solid foundation is critical for the long-term health of your pool. After the hole is dug, we spread a thick layer of 57 granite stones across the bottom of the excavation site. This creates a highly stable, shifting-resistant base for the pool shell to rest on, protecting it from ground movement over the years.

Setting the Pool Shell

This is often the most exciting day of the project. A crane carefully lifts your beautiful new fiberglass pool shell off the delivery truck and guides it into the excavation site. Our team makes sure the pool is positioned perfectly and leveled exactly to specification.

Plumbing and Electrical Work

With the shell securely in place, we move on to the pool’s circulation and power systems. Our technicians connect the plumbing lines to the pool’s filtration system, ensuring water will flow cleanly and efficiently. At the same time, we complete the electrical work required for your pumps, heating systems, and any underwater lighting you selected.

Back filling

Once the pool is set, leveled, and plumbed, we need to secure the sides. We back fill the space around the exterior of the pool shell with sand or gravel. This process stabilizes the pool in the ground and prevents it from shifting out of place as the earth settles.

Water Filling and Initial Testing

As we are back filling the exterior, we also begin filling the inside of the pool with water. Doing this at the same time helps equalize the pressure on the fiberglass shell so it settles perfectly. Once the water is in, we turn on the filtration system and test all the equipment to make sure everything operates smoothly. If you are looking for a reliable pool installation near me, our careful testing phase ensures you get a flawless result.

Decking and Finishing Touches

A pool is not complete without a beautiful area surrounding it. After the back filling is finished, we move on to the decking and coping. This is when your pool truly starts to look like a backyard resort. We add your chosen materials, install steps, and add any custom water features you requested.

Final Inspection and Cleanup

We pride ourselves on leaving your home better than we found it. We conduct a thorough final inspection of the pool, the equipment, and the surrounding area. We make any necessary adjustments, clean up the construction debris, and hand the pool over to you. It is finally ready for use!

Elevating Your Space with Custom Hardscaping

Your swimming pool is the centerpiece of your backyard, but the surrounding environment is what truly creates a personal paradise. We partner with Alyssa Winfield Designs to combine her visionary expertise with our expert craftsmanship. Together, we look at your entire yard and create an outdoor space that perfectly matches your lifestyle.
Our design options can easily be adjusted to suit your budget. You might start with a simple pool and hardscape plan featuring clean turf lines. Alternatively, you might want a more elaborate setup with large plantings, detailed bedlines, and custom patio construction. When you need a skilled pool and hardscape company near me, we have the experience to build patios, walkways, and lounging areas that elevate the beauty of your home.

Adding a Spa for Ultimate Relaxation

Many families choose to add a spa alongside their new pool, or as a standalone addition to their patio. At Ocean Blue Pools and Spas, we are Wilmington’s largest hot tub and spa dealer. We carry top brands known for durability and efficiency, including Bullfrog Spas, Viking Spas, and PDC Spas.

Soaking in a spa offers incredible benefits for both your physical and mental well-being. The warm water and hydrotherapy jets help to relieve muscle tension, alleviate joint pain, and improve your daily circulation. Regular spa use can also reduce anxiety and promote much better sleep. If you have a stressful job or suffer from arthritis, a backyard spa provides amazing daily therapy right outside your back door.

Real Stories from Our Happy Customers

We believe that our work speaks for itself, but we also love hearing from the families we have helped. Over the years, we have built strong relationships with our clients by prioritizing communication and stress-free service.
For instance, Janice S. shared her thoughts on her recent project: “This experience with Ocean Blue Pools was amazing. Great communication, perfect concrete work, and the final result was amazing. We love our pool and cannot thank them enough for the easy, stress-free experience.”
