A burst pipe on a Friday night or a floor drain overflowing in a closed shop is a business emergency, and our 24/7 line at (617) 752-0573 is staffed for it. While you wait, close the main shutoff, move stock off the floor, and photograph the damage.
Emergency commercial plumbing in Dedham, MA means licensed plumbers work on pipes, drains, fixtures and backflow devices in shops, restaurants, offices and multi-tenant buildings, and respond to after-hours failures.
Who owns the problem: landlord, tenant or manager.
Most commercial calls stall on one question: whose pipe is it? The answer depends on the lease, so read it before you call, but do not delay the shutoff. Stop the water first and sort out responsibility after.
| Situation | Usually the first call | Why. |
|---|---|---|
| Burst line inside a tenant suite | Tenant calls us, then notifies the landlord | Stops damage to stock and neighbors. |
| Shared riser or building main | Property manager or owner | Affects multiple tenants. |
| Grease trap or kitchen drain | Restaurant operator | Typically the tenant's equipment. |
| Backflow device test or repair | Owner or the party named in the lease | DWWD tests for a fee and repairs fall on the owner. |
| Roof drain or storm drain overflow | Owner or manager | Common-area system. |
Property managers: ask us to document what we find, so your tenant and your insurer see the same facts. If you manage several sites, keep each building's shutoff location in one sheet.
The Dedham commercial map and what it means for plumbing.
Providence Highway (Route 1), Route 1A, Route 109 and the I-95 and Route 128 corridor carry the town's commercial life, and the Master Plan names retail and office centers such as Dedham Mall, Legacy Place and Dedham Corporate Center.
We do not claim to serve any particular property. The point is what that kind of building brings: restaurants and food courts with grease, large paved lots with storm drains, and tenant suites sharing risers.
Before you hire, ask three things of any contractor: do they hold a Massachusetts plumbing license, will they pull permits where the work requires them, and can they work around your hours. Plumbing in a shared building also means coordinating with the property manager about water shutoffs.

Call (617) 752-0573Backflow testing and the DWWD Cross Connection Control Program.
The Dedham-Westwood Water District runs a Cross Connection Control Program mandated by MassDEP. The District surveys commercial, industrial, institutional and municipal sites, and the backflow devices it identifies must be tested every six months as a fee-for-service. When a device fails, repairs are done by independent firms at the owner's expense. That is where a licensed plumber comes in.
For you, a failed test is a deadline, not a nuisance. Ask the plumber if the repair needs a permit, since code sets conditions for reduced-pressure-zone devices. Keep your test records together, and ask DWWD (781-329-7090) how to schedule a retest after repair. The District also recommends hose-bib vacuum breakers on hose connections, a cheap fix worth doing at any site with outdoor spigots.
Grease traps and kitchen drains.
A grease trap catches fat before it leaves the kitchen. When it fills, the drain slows, smells rise from floor sinks and the line backs up at the busiest time. We found no Dedham rule on pumping schedules, so we cannot cite one. Ask your landlord, your insurer and the Town engineering office whether a requirement applies to your building.
For service, ask the plumber what gets removed, how the trap is cleaned and where the waste goes. A kitchen that cleans on a regular cycle, rather than after a failure, saves the cost of a Saturday backup. If the kitchen drain behind the trap keeps clogging, see hydro jetting for the line itself.
Storm drains and roof drains.
Large lots shed rain into catch basins, and leaves and silt clog the grates. The Town runs separate sanitary and stormwater systems, so a lot drain on private property must go to stormwater and never to the sanitary sewer. Boston-area annual precipitation averages 43.59 inches (NOAA 1991-2020, Boston Logan), enough that a blocked drain turns into ponding.
Ask us to clear basin grates, roof leaders and trench drains before the wet months, and to flush them to check flow.
Commercial leak detection, honestly.
Leak detection in a commercial building is useful when the water bill climbs, a ceiling stains below a roof or riser, or a slab stays damp. It uses acoustic listening, thermal imaging and pressure tests to narrow down a leak, and it can narrow it down a lot, but it cannot see through everything.
Metal, concrete and noise limit results. A typical approach is to isolate zones by closing valves, then listen. For more detail, see leak detection.
Repair options and honest trade-offs.
- Repair in place: fastest and cheapest when the pipe is sound outside the damaged section..
- Replace a run: sensible when corrosion appears along the whole pipe..
- Reroute: worth it when a pipe sits in an inaccessible chase..
- Temporary fix tonight, permanent repair next week: reasonable when a business must open in the morning, as long as everyone knows it is temporary..
What commercial plumbing work costs.
Cost depends on:
- Pipe size and material, plus how much of the building must be shut off..
- After-hours dispatch versus a scheduled visit..
- Access: ceilings, chases, slabs, rooftops and tight mechanical rooms..
- Permits, inspections and coordination with the property manager..
- Equipment: trap pumping, jetting or testing devices needed..
Business property insurance generally covers sudden and accidental damage rather than wear and tear, so ask your insurer and your landlord's insurer who covers what. Want your real number? Call (617) 752-0573.
What to do while you wait.
- Close the main shutoff, and the shutoff to the affected suite if there is one..
- Move inventory, files and electronics off the floor..
- Photograph damage with date stamps for the insurer..
- Notify the property manager if the leak could affect other tenants..
- For a sewer backup, stop using fixtures and keep staff out of the area..
Frequently asked questions.
.
Yes. The 24/7 line takes commercial calls at any hour. We do not promise a specific arrival time on the phone, because it depends on the plumber's location, but we tell you how to protect the site while you wait.
.
It depends on your lease. As a rule, whoever owns the pipe pays, but do not wait to settle that. Stop the water, call us, and notify the landlord in writing. Ask both insurers who covers the loss.
.
DWWD surveys commercial and similar sites, tests identified devices every six months as a fee-for-service, and expects owners to pay independent firms for repairs. Ask DWWD whether your site is on its list.
.
We dispatch licensed plumbers and can document each site. We do not name equipment or clients, but we can work from your shutoff map and your list of priority sites.
.
We service grease traps in general. We found no Dedham pumping rule, so ask the Town about your building before you set a schedule.
.
Often, yes, but not always. Acoustic and pressure tests narrow it to a zone, and sometimes the slab must be opened. Ask what happens if the first test is inconclusive.
.
Yes. Neighboring towns such as Westwood and Norwood have their own pages. If your site is a rental, you may also want to read about water line repair for the supply side.
