IS Plumbing is your licensed plumber in Westborough, MA — serving the town's neighborhoods along the Route 9 and I-495 corridor with plumbing, heating, gas fitting and drain work.
Westborough's mix of newer subdivisions and older homes near the center means we see modern systems and aging ones alike. We handle water heater and boiler installation, gas fitting, bathroom remodels, repiping and drain service — clean, permitted and inspected, with fast response from our nearby Millbury base.
Westborough splits between an 18th-century town center — where homes carry generations of plumbing decisions — and the newer subdivisions and corporate corridor along Route 9 and I-495. In the older stock we repipe and rework what previous decades left behind; in the newer, it's water heater replacements arriving on schedule as builder-grade tanks from the 2000s age out together.
Permits file with the Town of Westborough, inspections included. We also take light-commercial calls along the Route 9 corridor — office and retail tenant fit-outs, water heater and fixture swaps, and backflow protection where the water service requires it.
