A plain-English guide to how fiberglass pools work, why they suit our stretch of the coast, and what the process actually looks like — from Leeward, a new local fiberglass pool company.
Design my pool — freeA fiberglass pool is a single, pre-engineered shell — molded and finished at a factory, then delivered to your home and set into a prepared hole in one piece. Because the hard part is built before it ever reaches your yard, the on-site work is mostly excavation, setting, plumbing and decking.
That's the opposite of a concrete pool, which is dug, formed, steel-tied, sprayed and cured in place over many weeks. The fiberglass approach means less time, less mess, and a finished surface that's smooth from day one.
It's the fastest-growing pool type in the United States — and for good reason on a coast like ours.
Our soil is sandy and our water table is high. That's exactly the environment where a flexible shell earns its keep.
The shell arrives finished, so the yard isn't a job site all season.
A non-porous gelcoat resists algae and pairs naturally with saltwater.
The shell moves with shifting, sandy ground instead of fighting it.
Modern gelcoat finishes resist fading and staining for decades with normal care.
Every yard is different, but most fiberglass installs follow the same arc. Here's the honest, general version — timing varies with permits, access and weather.
Choose a shell and layout, confirm placement, and sort out permits and any HOA approval.
The hole is dug and graded to the shell's exact dimensions and leveled.
The pool is craned into place, leveled, and backfilled as it's filled with water.
Pump, filter and any automation are connected; saltwater systems are set up here.
Coping and decking — paver, travertine or concrete — frame the pool and tie it to the yard.
Water chemistry is balanced, equipment is tested, and you get a walkthrough before the first swim.
Nobody publishes this, so here it is. Four things move the number here that don't move it in Raleigh.
Access. The shell comes in one piece on a trailer and gets craned in. If the crane can park in the driveway that's one job. If it has to reach over the house from the street, that's another. This is the single biggest swing and it has nothing to do with the pool you picked.
What the ground does when we open it. Sandy and dry is easy. Water in the hole means pumps and a dewatering line, and that's the difference between a normal dig and a long one.
Reviews. On the island there's a CAMA determination, a floodplain permit, and sometimes a sealed V-Zone certification. Inland in Burgaw or Rocky Point there's none of that. Same shell, different paperwork, different cost to get it in the ground.
Trees. In Wilmington, working around a live oak you're not allowed to remove changes the equipment and the day.
That's why I won't quote a pool over the phone. Two identical shells a mile apart aren't the same job, and anyone who gives you a number before walking your yard is guessing at your expense.
No. Leave it full. This is the one thing I'd want every pool owner on this coast to know, and most people have it backwards.
The water in your pool is what holds the pool down. Take it out, then put ten or twelve inches of rain into the ground around it, and there's nothing left to resist the water pushing up underneath. That's when a pool floats: empty, in saturated ground. It'll take the plumbing, the wiring and the deck with it.
A full pool is fine. It's built to hold water and it can overflow without hurting anything. The rain running over the coping is doing what a patio would do in the same spot. Pull the pump motor if you're going to flood, throw a shock in before the storm, get the furniture inside instead of in the pool, and leave the water alone. The full storm guide covers evacuating, flood water, and the cleanup after.
The shell arrives finished, so the part that takes concrete two to six months is already done before the truck shows up. Once the hole's open, getting a shell set and swimmable is fast.
That's not the whole answer though. What sets your calendar is everything before the digging: the permit, the HOA if you have one, utility locates, and whether a truck and crane can physically get to your backyard. I've seen the pool part take a week and the paperwork take two months. Anybody who gives you a date before they've seen your yard is telling you what you want to hear.
