Sewer backup and sewer repair across Brooklyn
Brooklyn sewer backups follow the map. Red Hook, Gowanus, Canarsie, Sheepshead Bay and Gerritsen Beach sit low and back up when the combined sewer surcharges in a storm; a backwater valve is the fix, not another clearing. Brownstone neighborhoods have original clay and cast iron house sewers that roots have found: Park Slope, Carroll Gardens, Bed-Stuy and Crown Heights produce most of our Brooklyn lining and replacement jobs. The house sewer runs from the building to the city main under the street, and the owner is responsible for all of it; we pull the DEP and DOT permits and restore the sidewalk.
Our shop is at 854 Humboldt Street in Greenpoint, so Brooklyn is home turf: most of the borough is under 30 minutes from the truck.

Questions from Brooklyn
Who do I call for a sewer backup in Brooklyn?
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 Brooklyn 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 Brooklyn 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 Brooklyn?
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 Brooklyn 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.
