Cast-Iron Sewer Stack & Drain Repiping

Cast-Iron Sewer Stack & Drain Repiping Service

Century-old cast-iron stacks corrode from the inside out, cracking at the hub joints and inviting sewer gas and leaks into your walls. We camera-inspect the full run, then replace compromised stacks and drain lines with properly pitched PVC or no-hub cast iron — permitted, inspected, and backed by written warranty.

Cast-Iron Sewer Stack & Drain Repiping

Century-old cast-iron stacks corrode from the inside out, cracking at the hub joints and inviting sewer gas and leaks into your walls.

  • ✓ Code-compliant installation
  • ✓ Upfront agreed pricing
  • ✓ Workmanship warranty included
02

Galvanized Supply Line Upgrades & Repiping

If your taps spit rust-colored water or the shower goes cold when the washing machine fills, decades-old galvanized pipe is likely choked with internal scale. We repipe homes to copper or PEX in sections or whole-house, restoring strong, clean pressure without tearing your walls apart unnecessarily.

  • ✓ Code-compliant installation
  • ✓ Upfront agreed pricing
  • ✓ Workmanship warranty included
03

Hydronic Boiler Service & Freeze Protection

New England winters are hard on boilers — a failed circulator pump or unprotected outdoor line can freeze and burst overnight. We perform combustion tune-ups, replace zone valves and circulators, and add proper glycol charge and pipe insulation so your hydronic system rides out the coldest Merrimack Valley snaps without a hiccup.

  • ✓ Code-compliant installation
  • ✓ Upfront agreed pricing
  • ✓ Workmanship warranty included
