Sewer backup and sewer repair across Manhattan
Manhattan sewer backups are building backups: a house sewer under a Harlem or Upper West Side building serves dozens of apartments, and a backup fills the basement laundry room and the super's apartment first. We clear from the house trap or cleanout, camera the run to the street, and coordinate the DEP and DOT permits for any repair under the sidewalk, which in Manhattan also means working around vaults and utilities. Restaurants with grease-choked lines in Midtown and the Villages get emergency clears and then a jetting schedule.
Manhattan is one bridge or tunnel away from our Greenpoint shop. We know the freight-elevator hours, the certificate-of-insurance paperwork and the alternate-side parking that make or break a Manhattan service call.

Questions from Manhattan
Who do I call for a sewer backup in Manhattan?
Call GW Mechanical Corp at 646-980-2411, any time. Stop using water in the building first. We clear the line, camera it, and repair the cause.
Why does my Manhattan basement flood when it rains?
The city sewer is backing up into your house line. A backwater valve on the house sewer closes during storms and keeps sewage out of the basement.
Do you respond to sewer backups in Manhattan at night?
Yes, 24/7. Stop using water in the building, keep people away from the water, and call. We clear the line first and plan the repair second.
Who is responsible for the sewer line under the sidewalk in Manhattan?
The property owner, all the way to the connection at the city main. Work there needs DEP and DOT permits and a licensed master plumber, which we provide.
Why does my Manhattan basement back up only in heavy rain?
The city sewer is surcharging and pushing back into your line. A backwater valve on the house sewer closes when that happens and keeps sewage out of the basement.
