Plumber in Gowanus, Brooklyn

Full-service plumbing for homes, two-families and multi-family buildings across Brooklyn and Queens. Supply lines, waste lines, valves, fixtures and everything in between.

Gowanus has some of the oldest surviving residential building fabric in Brooklyn, with pre-Civil War wood-frame houses and Greek Revival brick rowhouses dating to the 1840s and 1860s built to house workers in the canal-side factories and iron foundries. Buildings this old were originally plumbed with iron supply and cast-iron waste — galvanized steel wasn't yet standard — and many retain those original systems under layers of later renovation work. The canal's industrial use through the mid-20th century suppressed residential development, which means Gowanus largely missed the 1920s and 1930s apartment-building waves common in surrounding neighborhoods. The post-2010 rezoning and conversion activity has introduced modern plumbing into many buildings, but the oldest row house stock is among the most historically layered residential plumbing work in Brooklyn.

Gowanus 1850s building water pressure low cause and fix

Low water pressure in Gowanus's 1840s-1860s row houses is almost always a mineral accumulation problem in original iron supply lines that have narrowed progressively over 150-plus years of service. These buildings predate galvanized steel as a supply material — they were originally plumbed with iron pipe, which corrodes from the interior in a pattern called tuberculation that can reduce a 3/4-inch nominal pipe to an effective bore of 1/4 inch or less without any visible exterior sign of deterioration. Unlike galvanized supply in 1920s buildings, where replacement has been common since the 1980s, some Gowanus row houses still have original or very early iron supply in wall chases because the building's development was suppressed by industrial canal use through the mid-20th century — meaning fewer renovation cycles and more surviving original material. A whole-building repipe with copper or PEX is typically the only lasting fix once pressure has dropped to the point where upper floors are affected.

Gowanus canal-adjacent building drain smell what causes it

Buildings immediately adjacent to the Gowanus Canal — a federal Superfund site with documented contamination — can experience drain odor issues that originate outside the building's own plumbing system. The canal's anaerobic sediment produces hydrogen sulfide and methane, and buildings with deteriorated house traps, cracked sewer lateral connections, or inadequate sewer venting can draw these gases into the building drain system from the city sewer, which in turn connects to the canal outfalls. In the 1840s-1860s row houses closest to the canal, original clay or brick sewer lateral connections may have deteriorated at joints, creating pathways for soil gases to enter the drainage system independent of any issue with the in-building plumbing. We distinguish between odor coming from the building's own drain traps — which dry out and allow sewer gas in — and odor coming from a compromised lateral connection, because the solutions are completely different.

Gowanus post-2010 loft conversion new plumbing rough-in on upper floors

Post-2010 residential loft conversions in the canal-adjacent Gowanus industrial buildings involve new plumbing rough-ins in structures that were never designed for residential use — no existing drain stacks, no established wet wall locations, and floor-to-floor heights that differ from standard residential construction. These projects require establishing new drain stack locations with adequate slope to connect to the building's existing waste connection, which in older industrial buildings may be a large-diameter clay or cast-iron line at grade designed for industrial effluent rather than residential fixture loads. We've done complete rough-in packages in Gowanus loft conversions that involved core-drilling through existing concrete slabs to establish stack penetrations and installing new sanitary systems from connection to roof vent. The open floor plans in these conversions allow flexible wet wall placement that isn't possible in the surrounding 1850s row houses where structural masonry constrains routing.
