Expert Solutions for Stow Homes

From scheduled maintenance to major infrastructure overhauls, executed to the highest trade standards.

01

Cast-Iron Sewer Stack Repiping

We replace corroding cast-iron drain and vent stacks with properly sloped PVC or no-hub systems, including cleanout installation and permit filings. Ideal for century-old triple-deckers and colonial homes showing chronic clogs, sewer gas odor, or rust-stained ceilings.

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

Galvanized Line Replacement & Repipes

If your faucets run rusty or your shower pressure fades the moment the washing machine starts, failing galvanized supply piping is usually the culprit. We repipe entire homes in PEX or copper — with new shutoffs, pressure regulation, and minimal drywall disruption.

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

Hydronic Boiler Service & Freeze Protection

From annual combustion tune-ups to emergency no-heat calls, we service gas and oil-fired hydronic boilers with glycol level checks, zone valve and circulator repair, and low-temperature safeguard settings. Recommended every fall before Massachusetts' first hard freeze.

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