Leaks, pipes & freezing in Honolulu, HI
Pipe problems range from a burst line that needs the water shut off right now to slow pinhole leaks that show up as a high water bill. A licensed plumber finds where the water is escaping, repairs or replaces that section, and tells you whether the rest of the piping is likely to follow.

Leaks, pipes & freezing services in Honolulu
Burst pipe repair
UrgentTurn off the main water shutoff first, then open a faucet on the lowest floor to drain the lines. A plumber cuts out the split section, replaces it, and checks the rest of that pipe run, because one freeze rarely damages only one spot.
Frozen pipe thawing
UrgentIf a faucet gives no water or only a trickle after a hard freeze, a pipe is frozen. Leave that faucet open, warm the area gently, and call a plumber if you can't find the frozen section or if it's inside a wall, because a split pipe will leak as soon as it thaws.
Leak detection in Honolulu
Turn off every fixture and watch the water meter's leak indicator. If it moves, water is leaking somewhere. A plumber uses pressure tests, acoustic listening and thermal imaging to find the leak so only a small section of wall or floor has to be opened.
Repiping in Honolulu
Repiping replaces a home's water supply lines, usually because old galvanized steel has corroded or polybutylene is at risk of failing. Most repipes today use PEX, take two to five days, and are done through small wall openings rather than gutting the house.
Water line repair
UrgentThe water service line runs from the curb stop near the street to your house, buried below the frost line. A leak shows up as a soggy patch in the yard, low pressure throughout the house, or a meter that never stops. Repair means finding the leak, then fixing that spot or replacing the line.
Local conditions
Leaks, pipes & freezing in Honolulu: what's different
Honolulu never sees frozen pipes, but salt air and humidity corrode metal pipe and fittings, and older homes in Kaimuki and Kalihi still have galvanized supply. Single-wall homes often have exposed plumbing that corrodes faster.
Many residents live in older high-rises where building plumbing affects every unit, so a leak may need building management involved.
The Honolulu Board of Water Supply provides water from underground aquifers and promotes conservation. Permits come from the Department of Planning and Permitting.
