Your Local Kapaa Plumbing Company
When you search “plumber near me” or “best plumber in Kapaa”, you want someone who shows up fast, fixes it right and charges what they quoted. That's what JW Moore Plumbing has built its reputation on across Kauai. Our residential and commercial plumbers in Kapaa handle everything from a toilet that keeps running to a full sewer line replacement, and our emergency plumbers are on call around the clock — nights, weekends and holidays — with no overtime fees.
Kapaa homes and businesses deal with a unique mix of plumbing challenges: mineral-heavy water that scales water heaters and fixtures, salt air that corrodes older galvanized pipe, tree roots that invade sewer lines, and heavy rains that overwhelm drains and sump pumps. We stock our trucks for these exact problems so most repairs are finished on the first visit.
