Why We Can Offer This
We only install what we'd put in our own homes
Cade started Intracoastal Water by installing the first system in his own home. Joe followed in his. The 20-year warranty isn't a marketing claim. It's a statement about what we're willing to stand behind.
We partner with manufacturers that build systems to last 20+ years. We don't install systems that need replacing in 5. That's how we can back every installation the way we do.
No other company in Wilmington offers a 20-year manufacturer warranty. If you're comparing quotes, ask every vendor what warranty they offer. Then decide.
