Water & Sewer Line Services — South Shore Massachusetts
Many older South Shore homes were built with plumbing materials that have long exceeded their useful life. Cast iron drain pipes, galvanized steel supply lines, and old brass fittings all eventually corrode, crack, or fail. AJM Plumbing & Heating replaces and repairs interior water and sewer lines across the South Shore — before they cause a major problem in your home.
Interior Water Supply Line Replacement
Old galvanized steel and brass water supply lines corrode from the inside out, reducing water pressure, discoloring your water, and eventually leaking. We replace aging interior supply lines with modern materials — copper or PEX — that deliver cleaner water and won't fail for decades. We serve all South Shore communities from Quincy to Duxbury.
Interior Drain & Sewer Line Replacement
Cast iron drain pipes in older South Shore homes eventually rust through, crack, and collapse. Signs include slow drains throughout the house, frequent clogs, sewer gas odors, and wet spots in the basement. We replace failing interior sewer and drain lines with durable modern materials and restore proper drainage throughout your home.
When to Replace vs. Repair
Not every drain or supply line issue requires full replacement. Spot repairs are often possible for isolated problems. We'll assess your situation honestly and give you a straight recommendation based on the age and condition of your system — not on what's most profitable for us.
Serving South Shore Homes of All Ages
We regularly work on older homes throughout Quincy, Braintree, Rockland, Hingham, and other established South Shore communities where original plumbing is now 50–100 years old. Please note that all our water and sewer line work is performed inside the home — we do not handle exterior water main or sewer line work.
