What We Do
Whole-Home Repipe (PEX)
PEX is our default material for water lines — flexible, freeze-resistant, no soldered joints to fail. Color-coded blue and red for cold and hot, and a clean manifold for easy maintenance.
Copper Repipe
When you want copper — visible runs, exposed mechanical rooms — we install type-L copper with soldered or pressed joints.
Drain Line Repipe (PVC)
Old cast iron and clay drain, waste, and vent lines crack, rust, and clog. We replace failing drain lines with new PVC for decades of reliable, quiet drainage.
Galvanized & Polybutylene Removal
We're seeing failures of polybutylene from the 1980s and 1990s every month. Don't wait for the flood. We remove the old material and run new plumbing through walls and ceilings with minimal demo.
Water Service Line Replacement
From the city main to your house — old galvanized or lead service lines are a known issue in older Kalamazoo neighborhoods. We replace with copper or PE, with proper permits and inspection.
Manifold Plumbing
Modern home-run plumbing with a central manifold gives you isolated shutoffs at every fixture and far less pressure loss.
Signs You May Need a Repipe
Noticing any of these? It's time to call a licensed plumber.
Recurring pinhole leaks
One patch, then another, then another.
Rusty or discolored water
Corrosion shedding into your supply.
Galvanized or poly pipe
Materials known to fail with age.
Low pressure everywhere
Mineral buildup narrowing the pipes.
Discoloration at first flow
Rust sitting in the lines overnight.
Repair after repair
At some point, replacement wins.
