Ann Arbor Epoxy Pipe Coating: Renew Supply Lines In Place

Ann Arbor epoxy pipe coating renews aging water supply lines from the inside, bonding a smooth protective barrier to corroded copper and galvanized pipe to seal pinhole leaks and stop further corrosion. Applied to ½-inch through 4-inch lines, it's a natural fit for the city's historic homes: rather than opening original plaster walls for a full repipe, coating restores the existing pipe in place — exactly the kind of minimal-disruption work that owners in the historic districts prefer. This guide explains how epoxy coating works, how it differs from sewer lining, what it costs, and how to find qualified Ann Arbor contractors.

What Epoxy Coating Solves in Ann Arbor

Epoxy coating protects supply pipe that's corroding but still sound. Systems such as Nu Flow and ePIPE coat the line in place, which suits Ann Arbor's older housing especially well.

Pinhole Leaks in Historic Homes

The original copper and galvanized water service in the historic neighborhoods springs pinhole leaks as the wall corrodes from inside. Rather than chase each leak by opening original plaster, a coating seals the interior across the whole run and stops them at the source.

Corroded Galvanized Lines

Galvanized supply lines scale and corrode internally, narrowing flow and discoloring water. Coating renews a smooth interior without tearing out finished walls for a full repipe.

The Minimal-Disruption Choice

For owners in Ann Arbor's historic districts, preserving original interior finishes matters. Because coating works through the existing pipe with little wall demolition, it's the low-impact option that keeps a historic home's character intact.

How Ann Arbor Epoxy Pipe Coating Works

The process renews the pipe in place through existing connections. The standard workflow:

1. Inspection & Assessment

The line is evaluated to confirm the pipe is structurally sound enough to coat rather than replace.

2. Cleaning & Drying

The interior is cleared of scale with an abrasive air process and dried so the epoxy bonds to bare metal.

3. Epoxy Application

A two-part epoxy resin is blown through the line, building an even barrier — related to spray lining.

4. Cure & Verify

The coating cures to a hard, seamless surface, then flow and pressure are checked before the line returns to service.

Epoxy Coating vs. CIPP Pipe Lining

The two are easily confused but solve different problems. Epoxy coating applies a thin barrier inside small pressurized supply lines — the ½-inch to 4-inch copper and galvanized pipe carrying water to your fixtures. CIPP pipe lining installs a thicker structural liner inside larger gravity sewer laterals to bridge cracks and joints. In short: coating renews supply pipe; lining rebuilds sewer drains. A material review confirms which your property needs.

Ann Arbor-Specific Cost Factors

Frequently Asked Questions

Is epoxy coating the same as pipe lining?

No. Epoxy coating applies a thin barrier inside small pressurized supply lines, while CIPP lining installs a thicker structural liner inside sewer drains. Coating renews supply pipe; lining rebuilds sewer laterals.

Why is coating a good fit for a historic Ann Arbor home?

Because it works through the existing pipe with little wall demolition, coating seals leaking supply lines without tearing out original plaster and finishes — the minimal-disruption approach owners in the historic districts prefer.

Is epoxy coating safe for drinking water lines?

Yes, when a potable-rated, certified coating system is used by a trained applicator. Confirm your contractor uses a product approved for potable water before work begins.

Can my old galvanized pipe be coated?

Often yes, if the pipe still holds its structure. Severely corroded or thin-walled pipe needs replacement instead, which is why an inspection always comes first.
