Pipe Brush Coating 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
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.
Don't Wait
Signs Your Pipes May Benefit From Brush Coating
Rust-colored or discolored water, especially when first turned on
Metallic taste in tap water
Pinhole leaks in copper pipes — especially in the same general area
Home was built before 1970 with original galvanized steel pipes
Reduced water pressure throughout the house
Pipes are in walls, ceilings, or slabs — difficult to access for replacement
Multi-unit building with aging supply lines throughout the structure
Recent water test showing elevated copper, iron, or lead levels
Common Questions
Frequently Asked Questions
Is epoxy brush coating safe for drinking water?
Yes — coatings used for potable water applications are NSF/ANSI 61 certified, meaning they're approved for contact with drinking water. The cured epoxy is inert and does not leach chemicals into the water supply.
How long does a brush-coated pipe last?
A properly applied epoxy coating can extend pipe life by 10–15 years or more. The coating protects the pipe interior from continued corrosion and seals existing damage. The original pipe condition and the environment affect long-term performance.
How is brush coating different from CIPP pipe lining?
CIPP (like our LightRay UV system) installs a structural fiberglass liner that becomes a new pipe inside the old one — primarily used for drain and sewer pipes. Brush coating applies a thinner epoxy barrier layer to the interior of supply pipes, primarily to address corrosion and water quality rather than structural failure.
Can brush coating fix a pinhole leak?
It can seal small pinholes and corrosion sites as part of the coating process, but a pipe with active leaks needs to be assessed carefully. Active leak points may need spot repair before or alongside coating. We inspect thoroughly before recommending a solution.
