Drains and Pipes Done Right

Slow kitchen drain? Toilet backing up? Water stain on the ceiling? We handle it. Drain cleaning, pipe repair, pipe replacement, and sewer line work for homes and businesses across SE MA and RI.

Our plumbers clear clogs with professional equipment, not a bottle of Drano. Persistent blockages get a camera down the line so we see exactly what is happening before we dig. If the pipe is the problem, we repair or replace the section.

If the issue involves gas lines, our licensed gas techs handle it. If it traces to an electrical problem with a pump, our electricians are on it. One company, no referrals, no finger-pointing.

What Does Drain Service Cost in SE MA / RI?

Drain cleaning runs $250 to $500 for most residential clogs. Kitchen sinks and tubs sit at the low end. Main line clogs cost more because they take heavier equipment and more time.

A camera inspection adds $500 to $1,000. We recommend it for any recurring clog, since clearing the same blockage twice costs more than finding the cause once.

Pipe repair ranges from $300 to $2,000 depending on access and scope. A section under a sink is quick. A pipe behind a finished wall or under a slab is not.

Sewer line work is quoted after camera inspection. No two sewer jobs are alike, so we will not guess at a number before we see the line.

Why Homeowners Choose Triangle for Drain & Pipe Work

In-House Electricians

Most HVAC installers sub out the panel work. That means two companies, two schedules, two invoices. Our own electricians handle the panel work. One company, one invoice.

Mass Save Participating Contractor

We know which systems qualify, what documentation the program requires, and where homeowners usually lose money by picking the wrong equipment tier. We confirm your eligibility before you spend a dollar.

55 Years. Not a Startup.

Rebate money brought a lot of new companies into this market. Triangle has been at 425 Pleasant Street in Fall River since 1970. When your compressor needs warranty service in 2030, we will still be here.

Four Trades, One Company

Getting a mini split and notice the water heater looks rough? Want a generator quote while we are there? Heating, cooling, plumbing, electrical, refrigeration. One call, one truck, one bill.
