Emergency Commercial Plumbing in Melrose, MA

When water is spreading across a shop floor or a restaurant kitchen is down, our 24/7 line is open. Commercial plumbing is service work on the systems of a business or multi-unit building, from drains and grease traps to backflow assemblies and supply lines.

While you wait, block off wet walkways, close isolation valves for the affected zone if you know them, and keep staff and customers away from open or uncovered drains. Then call, and have the building address and a contact name ready for the dispatcher.

After-hours plumbing emergency at a business

A plumbing failure after closing is worse than one at noon. Nobody is there to see the water, and a restaurant or shop may sit flooded all night. We run an after-hours line for exactly that, and we ask a few direct questions so the right crew and tools go out.

Tell us what kind of building it is, where the water is coming from and whether you can reach a shutoff. Call the 24/7 line and we dispatch as soon as a crew is free.

Tell us how your facilities team wants work documented.

Where we work

  • Restaurants and food service. Kitchen drains, grease traps, dish and prep sinks and water heaters take daily abuse.
  • Apartment and multi-unit buildings. Shared stacks, laundry rooms and boiler rooms mean one failure affects many units.
  • Retail and office plazas. Restrooms, mop sinks, roof drains and shared supply lines.
  • Garages and service bays. Floor drains, oil separators and utility sinks.
  • Hospitality and large campuses. Long supply lines, irrigation and buried mains over wide areas.

Business flooded or kitchen down?

Call the 24/7 line. Give us the address, the building type and where the water is coming from.

Commercial services we handle

Grease trap cleaning

A trap catches fats and oils before they harden in the sewer. Many jurisdictions expect it cleaned when it is a quarter full. Check your own requirement with the authority that regulates your building, and we set a pump schedule that matches.

Floor drain service

Floor drains back up when debris builds or the trap dries out and lets sewer gas rise. We clear the line, flush the trap and, where needed, install a trap primer.

Backflow testing

A backflow assembly keeps dirty water from flowing back into the clean supply. Testing schedules and who receives the report are set by your water supplier and the state. Ask the Melrose water office what applies to your assembly. Melrose's plumbing fee schedule includes a $25 line for a residential backflow prevention device. Ask the city what applies to a commercial assembly.

Commercial leak detection

Abnormal meter readings, wet parking lots or a rising water bill point to hidden leaks. We use listening and electronic tools, then repair what we find. See leak detection for how the process works.

How a commercial service call runs

  1. 1

    Intake

    We take the address, building type, contact person and what is happening. Tell us how your facilities team wants work documented.

  2. 2

    Make safe

    The crew isolates the affected zone and controls the water or backup first.

  3. 3

    Diagnose

    Camera, locating gear or pressure tests find the cause, and we explain it before repair.

  4. 4

    Fix and document

    We repair or clear the problem, and provide a service note you can file for your records or your insurer.

Before we arrive

1

Name a contact

Someone who knows the building and can unlock mechanical rooms.

2

Locate shutoffs

Tell us which zones have isolation valves and where the main sits.

3

Protect inventory

Move stock, paper goods and electronics away from water.

4

Keep records handy

Have the last grease trap pump date and any notice from the water utility.

What changes the price of commercial work

Scope and building sizeA single restroom differs from a multi-floor stack or a campus main.
AccessRoof, ceiling and slab work add labor, as do buried lines under parking.
Service scheduleRecurring grease trap or drain maintenance is planned, while emergencies are priced for after-hours dispatch.
EquipmentJetting, cameras, locators and vacuum trucks each have their own cost.
DocumentationTest reports and work-order paperwork take time and are part of the job.
Insurance note. Commercial property policies often cover sudden water damage but not the worn part that failed. Ask your carrier about water backup coverage before you need it, and keep our service note. Want your real number? Call (339) 216-9771 and we quote the job before work starts.

Questions we hear

Yes. The dispatch line runs 24/7 and business emergencies are treated as urgent. We cannot promise an arrival time, but we help you contain the water and send a plumber as soon as one is free.

Yes. Recurring service keeps the trap from filling and backing up into the kitchen. We set the interval from your usage and any requirement from the authority that regulates your building.

Yes, we can help with backflow assemblies. Ask your water supplier how often your assembly must be tested and what happens if a test is missed.

Yes. Send the order with the site address, contact and scope, and we match our scheduling and service notes to it.

Yes. We can survey a whole property or spot check one line. See our water service line repair page when the leak is in a buried line.

A backup in several floor drains at once points to the building drain. We clear it with a camera and jetting, covered under hydro jetting.
