Ten minutes up Route 20 from our Millbury shop, Northborough sits deep inside IS Plumbing's fastest coverage zone. We repair and repipe the town's postwar capes and ranches, replace water heaters and boilers, run gas lines, clear drains and camera-inspect sewer laterals — all under Master Plumber License #17137, with permits filed and inspections passed on every single job.
Northborough's housing tells a steady growth story: capes and ranches from the postwar decades line the streets off West Main and Whitney Street, colonial subdivisions from the 80s and 90s fill the hills between Route 20 and I-290, and farm properties on the Ball Street side still anchor the town's rural edge. The older stock is where we spend most of our time — original copper and cast iron reaching end of life, boilers from two energy crises ago, and water heaters overdue for retirement. Proximity matters here: being one town over means Northborough calls get scheduled fast and finished without return-trip delays.
Town water serves Northborough's core neighborhoods while some outlying roads toward the Berlin and Boylston lines still rely on private wells, and municipal sewer likewise covers the denser streets with septic handling much of the rest. We check which combination a house has before quoting drain, treatment or fixture work.
Our Northborough permits are filed with the Northborough Building Department and inspected before we consider a job closed. The most common project in town is the postwar-home mechanical refresh: a modern water heater, updated gas piping and shutoffs, and often a boiler swap folded into the same visit.
"Fantastic experience. They did the plumbing for two bathroom renovations — our master bath and the kids' bath — and the whole process was smooth, professional, and on time."
"We hired IS Plumbing to replace a number of fixtures and toilets. Very professional crew and a great job. Highly recommend them for all your plumbing needs."
"Great experience — they installed an automatic smart water shut-off, did a full boiler maintenance with warranty parts, and explained everything clearly."

Usually, yes. The postwar homes off West Main Street often run boilers decades past peak efficiency; a high-efficiency replacement cuts fuel use (Mass Save no longer rebates gas or oil boilers, but the 0% HEAT Loan may still apply to eligible upgrades).
We start with a camera down the lateral — older lines near Northborough Center often show root intrusion or bellied pipe. Once we can see the cause, you get a repair plan instead of endless re-clearing.
On every job. We submit to the Northborough Building Department before work begins and stand with the inspector at the end, so the paperwork trail is complete when we leave.
Yes. On the outlying roads toward Berlin and Boylston we service pressure tanks and install softeners and iron filters, since local groundwater tends to carry the hardness and iron typical of Worcester County wells.
