Our Story

A Licensed Plumbing Contractor Serving Lawrence Since 2011

Aroso Plumbing Lawrence is a licensed plumbing contractor serving Lawrence, Massachusetts and the surrounding Merrimack Valley. Marco Aroso runs the company as Owner and Master Plumber, and he was working in this trade for years before the business opened in 2011. He learned the housing stock here the slow way, in stone foundation basements with 6 feet of headroom, cutting out cast iron that had rotted through at the floor line while the tenant upstairs waited to use the sink. That is still the work. The company stayed small on purpose so the person who quotes the job is the person who does it.

Every call starts with diagnosis, not a price. On a drain, that means finding out whether the blockage sits in the trap arm, the branch line or the building drain before a machine comes off the truck, because those are three different jobs at three different prices. On a leak, it means a static pressure test and a look at the meter before anything opens up. Once Aroso Plumbing Lawrence knows what the repair actually is, the price goes in writing before work starts. Anything that needs a permit gets one pulled under a Massachusetts plumbing license, and the rough and final inspections get scheduled through the City of Lawrence Inspectional Services Department.

  • The owner is on the truck. Marco Aroso quotes the job and does the job, so nothing gets lost between the estimator and the tech.
  • Permits pulled and inspections scheduled on every job that needs them, under 248 CMR 10.00.
  • Camera inspection on any recurring drain or sewer problem, so the recommendation is based on what the pipe looks like inside rather than a guess.
  • Multifamily and landlord work handled around tenants, including shared stack problems where one unit's clog surfaces in another.
  • One phone number, answered by a plumber, at 2 in the morning as readily as at 2 in the afternoon.

Testimonials

What Lawrence, MA Customers Say

“My kitchen sink drain kept backing up every few days from grease buildup in the old cast-iron line. Aroso Plumbing came out, ran a camera, and cleared the clog with a powered auger before replacing a cracked section of pipe under the floor. Water now drains straight through without any gurgling.”
CM Carlos M.South Lawrence, MA
“After the January freeze, our upstairs bathtub faucet started leaking steadily from a split supply line. The plumber isolated the line, swapped in new copper sections, and pressure-tested the whole run. The drip stopped and we haven't had any more ice-related issues since.”
ER Elena R.Prospect Hill, Lawrence
“Our water heater was delivering rusty water on the hot side and the pilot kept going out. They replaced the anode rod, flushed the tank, and installed a new thermocouple. Hot water is now clear and consistent, and the heater hasn't shut off unexpectedly in the two months since.”
DT David T.Arlington Mills, Lawrence

Plumber FAQs for Lawrence, MA

Still have questions? Call and talk it through with a plumber.

831-731-3360
+ Does plumbing work in Lawrence need a permit?
Most of it does. Replacing a water heater, altering or extending drain, waste and vent piping, replacing a water service line or sewer lateral, and moving or adding fixtures all require a plumbing permit in Lawrence. In Massachusetts that permit is pulled by the licensed plumber doing the work, not by the homeowner, which is different from many other states. Simple repairs like a faucet cartridge, a wax ring or a shutoff valve swap generally do not. Aroso Plumbing Lawrence pulls the permit and schedules the inspections as part of the job.
+ Who owns the water service line and the sewer lateral, and what does the city maintain?
The property owner generally owns and maintains the water service line and the sewer lateral from the building out to the connection at the city main, and the Lawrence Water and Sewer Department maintains the mains in the street. That means a collapsed lateral under your front yard is your repair, and a backup caused by a problem in the main is theirs. The dividing point is not always at the property line, so a camera inspection and a locate are how the responsibility gets established before anybody starts digging.
+ How fast can somebody come out on an emergency?
Aroso Plumbing Lawrence takes emergency calls 24 hours a day, 7 days a week, and response within the city is usually measured in under an hour depending on what is already in progress. On the phone you get told immediately whether the situation calls for closing the main shutoff, killing power to a water heater, or shutting a fixture stop, because that first minute is what limits the damage. Burst pipe volume in January is the one thing where a fast phone call matters more than a fast truck.
+ What makes a plumbing quote go up or down?
Access, materials, pipe condition and whether the work requires a permit and inspection. A toilet drain cleared through an existing cleanout in an open basement is straightforward. The same clog with no cleanout, a finished ceiling in the way and 90 year old cast iron that may not survive the machine is a different job. On repairs, whether the surrounding pipe is sound copper or tuberculated galvanized often decides whether a 1 hour fix turns into a section replacement. Nobody at Aroso Plumbing Lawrence gives a firm number before seeing the actual conditions.
+ Is Aroso Plumbing Lawrence licensed and insured?
Yes. Work is performed under a Massachusetts plumbing license issued by the Board of State Examiners of Plumbers and Gas Fitters, and the company carries liability insurance. Massachusetts also requires a separate gas fitting license for gas work, which is why a water heater changeover is treated as licensed gas work and not a generic appliance swap. Proof of license and insurance is available on request before work begins.
+ What happens if an inspection fails?
The inspector writes what needs to change, the contractor corrects it, and the inspection gets rescheduled at no cost to you. A failed rough inspection on work performed by Aroso Plumbing Lawrence is the company's problem to fix, not the customer's. This is one reason permitted work is worth the extra step: a documented final inspection is what proves the installation met 248 CMR 10.00 when you sell the building or file an insurance claim years later.
+ Do you work on old cast iron and galvanized piping in three deckers?
Yes, and it is a large share of the work here. Cast iron stacks in Lawrence three deckers scale internally, crack at the hub and spigot joints and rot out where the stack meets the basement floor. Galvanized supply tuberculates until the inside diameter of a 3/4 inch pipe is closer to 1/4 inch. Both need judgment about what to repair, what to replace and where to transition to copper or PEX with the right dielectric separation rather than a blanket recommendation to repipe.
+ Do you handle commercial and multifamily buildings?
Yes. Aroso Plumbing Lawrence works on multifamily buildings, converted mill space, restaurants and storefronts as well as single family homes. That includes shared vertical stacks where one unit's clog backs into another, grease traps and commercial kitchen drain lines, flushometer repair, backflow assemblies and cross connection control, and scheduling around tenants so a building does not lose water for a full day. Landlord turnover work between tenancies is routine.
