Sewer backup and sewer repair across Staten Island
Staten Island sewer backups are mostly roots and bellies in long house laterals, because lots are bigger and sewers run farther from the house to the street. Westerleigh, Great Kills, Eltingville, Annadale and Tottenville keep us busy with jetting, lining and replacement. Parts of the borough still have septic or newer sewer connections, and East Shore neighborhoods, Midland Beach, New Dorp Beach and Oakwood Beach, back up during storm surges, where a backwater valve on the house sewer is the single best protection for a finished basement.
We dispatch to Staten Island daily; the Verrazzano puts the North Shore 35 to 45 minutes from the shop, and we stage parts for South Shore calls so one trip finishes the job.

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