From the historic neighborhoods of Wilmington to the rolling estates of Greenville, Tri-State Aquatic Solutions brings premium pool craftsmanship to every corner of New Castle County. As a Hockessin-based company, we are not just serving this county - we are part of it.
New Castle County is home to nearly 60% of Delaware's population, and it is where we have chosen to build our business. Our headquarters in Hockessin puts us at the heart of the county, allowing us to serve communities from Pike Creek to Newark, from Brandywine to Bear, with the responsiveness and local knowledge that only a true neighbor can provide.
We understand that New Castle County properties are diverse - from the compact lots of urban Wilmington to the sprawling estates of Chateau Country. Each presents unique opportunities and challenges, and our years of building pools throughout the county have given us the expertise to handle them all.
Delaware's permit process is more straightforward than neighboring Pennsylvania, and our established relationships with county building departments help ensure your project moves smoothly from approval to completion. Combined with Delaware's no sales tax advantage on pool materials, New Castle County is an ideal place to invest in your backyard oasis.

"Living in Pike Creek, we wanted a local company that understood our neighborhood. Tri-State exceeded every expectation. The permit process was seamless, the crew was professional, and our fiberglass pool was installed in just three weeks. We have already referred them to two other families on our street."
Fiberglass pools are typically installed in 2-4 weeks from permit approval. Concrete pools take 8-12 weeks. Delaware's streamlined permit process often means faster start times than neighboring Pennsylvania.
Yes, all in-ground pools require a building permit from New Castle County. We handle the entire permit process for you, including application, plans, and coordination with inspectors.
Delaware requires a barrier (fence) of at least 48 inches surrounding the pool with self-closing, self-latching gates. We include barrier consultation and can coordinate fence installation as part of your project.
Delaware has no sales tax, which can save you thousands on pool materials. On a typical $75,000 pool project, this can represent $4,500-$6,000 in savings compared to a pool built in Pennsylvania (6% sales tax).
