It is hard to tell how long an in-ground pool construction will take (either fiberglass or concrete) as there are some unforeseen elements such as weather that can delay some projects but the average pool construction can take between 8-12 weeks. This accounts for design, permitting, excavation, plumbing and electrical, building, and adding any final deck and any final detailing, such as landscape features. Details are what we excel at, and we leave no stone unturned in our pursuit of your perfect pool.
