Pipe Brush Coating — Plumbing Leak Repair Without Excavation on O'ahu
Corroded supply pipes leach rust and metals into your drinking water, cause pinhole leaks, and reduce water pressure. Brush coating applies a durable epoxy barrier to the interior of existing pipes — restoring water quality and stopping corrosion without tearing out walls or concrete.

What We Do
Brush Coating Applications for Residential & Commercial Plumbing Services
Epoxy brush coating works across a range of pipe types and applications.
Potable Water Supply Line Coating
NSF-61 certified epoxy coatings are safe for drinking water contact. We apply the coating to corroded copper, galvanized, or iron supply lines — sealing rust, pinhole leak sites, and metal leaching without replacing the pipe.
Hot & Cold Water Distribution Coating
Both hot and cold water lines inside walls and ceilings can be coated in place. The process involves cleaning the pipe, applying epoxy, and allowing it to cure — all without opening walls.
Fire Suppression System Coating
Corroded sprinkler and fire suppression lines can be coated to extend their service life and prevent scale buildup that reduces flow rates — an alternative to expensive system replacement.
Chilled Water & HVAC Line Coating
Commercial HVAC and chilled water pipe systems corrode from the inside over time. Epoxy coating stops corrosion and prevents the buildup that reduces system efficiency.
Multi-Unit Building Pipe Rehabilitation
Older apartment buildings and condos with aging supply lines throughout the structure are ideal candidates for brush coating — rehabilitating all the pipes without disrupting residents or opening walls floor by floor.
Commercial & Industrial Applications
Hotels, resorts, office buildings, and industrial facilities on O'ahu use brush coating to extend the life of aging pipe infrastructure — avoiding costly full replacement and the building disruption that comes with it.
