Comprehensive, licensed solutions for homes and businesses in Holliston and surrounding areas.

Emergency Pipe & Leak Repair

Burst supply lines, pinhole copper leaks, and frozen pipe thaws handled fast with professional leak location and permanent repairs — not temporary patches. We isolate the failure, replace damaged sections in kind or upgrade to PEX, and pressure-test the system before we leave.

Heat Pump Mini-Split Conversions

Replace costly oil, propane, or electric-resistance heat with ductless and ducted cold-climate heat pump systems sized and commissioned for Massachusetts winters. We handle load calculations, line-set routing, electrical coordination, and the Mass Save rebate paperwork from start to finish.

Boiler Tune-Ups & Steam System Service

Annual combustion tune-ups, LWCO and pressuretrol testing, and skim treatment for steam boilers keep radiators heating evenly and fuel bills down. We service gas and oil fired hot-water and steam systems, replacing worn gaskets, vents, and controls before they fail mid-season.

Bathroom & Kitchen Plumbing Renovations

Full rough-in and finish plumbing for remodels — fixture setting, shower valve replacement, drain reconfiguration, and water heater upgrades including high-efficiency tankless units. Every connection is code-compliant, permitted where required, and built to serve for decades.
