Gas Piping in Corona, Queens

Licensed gas piping for new appliances, line replacements and system upgrades across Brooklyn and Queens. If you smell gas near equipment, call the utility first, then call us.

Corona built out primarily between 1920 and 1955, with the residential interior composed mainly of attached and semi-detached two-family and three-family brick houses on tight lots — working-class construction built for immigrant families who arrived in waves through the early and mid 20th century. That generation of building means galvanized supply lines and cast-iron DWV are the baseline in any unrenewed home, and original steam boilers survive in many of the older two-families and four-story walk-ups. Bathrooms in houses built between 1920 and 1940 frequently retain original hex tile floors and subway tile walls — a sign that the plumbing behind them is also original and overdue for evaluation. Corona's dense two-family stock generates steady boiler service, drain, and repipe work.

Local Law 152 gas inspection for Corona three-family or four-story walk-up

Three-family homes and four-story walk-up apartment buildings in Corona are subject to Local Law 152 gas piping inspection requirements, and the deadline cycle for these buildings depends on the Community Board district and the building's last filed inspection. Corona's residential stock includes both two-family homes below the LL152 threshold and three-family and larger buildings that are required to comply. Original black-iron gas distribution in these 1920s-1940s buildings runs from the building's meter through the basement and up vertical risers serving each floor, with branch lines to stoves and in some buildings original gas-fired water heaters. An LL152 inspection documents all accessible gas piping condition, identifies any prohibited materials or conditions, and results in a report filed with the NYC DOB. We conduct LL152 inspections in Corona's three-family and walk-up buildings, handle the DOB filing, and perform any corrective work identified — including repiping of sections that fail pressure testing.

Corona 1970s oil-to-gas conversion — is the original conversion piping still up to code?

Many Corona two-family homes converted from oil-fired to gas-fired boilers during the 1970s-1980s, and the gas piping installed during those conversions is now 40-50 years old. The conversion-era piping used materials and installation practices that met the code of that time but may not comply with current standards, and connections made with outdated thread sealants or flexible connector types that are no longer allowed require updating. Additionally, where the original 1920s-1940s interior black-iron gas distribution was left in place — serving the kitchen stoves on both floors — that older piping may not have been included in the conversion permit scope. We assess the full gas system in a Corona two-family: both the conversion-era boiler supply and the older interior distribution, performing a pressure test on the complete system to identify any leaking sections. Where corrections are needed, we pull the appropriate NYC DOB permit and perform the work in black iron matching the existing system configuration, then file for inspection.

New gas dryer or range in Corona two-family rental unit — permit required?

Installing a new gas appliance connection — a dryer, range, or any other gas-fired appliance — in a Corona two-family requires a licensed master plumber to make the gas connection and, in most cases, a NYC DOB permit for the gas piping work. New gas appliance connections that involve running new gas branch piping always require a permit and inspection; connections to an existing, properly sized and capped outlet stub may not, but the distinction is fact-specific. In a rental unit in a Corona two-family, the landlord is responsible for the gas piping infrastructure, and any modification to the gas distribution should be documented and permitted to protect both the owner and tenant. We handle appliance gas connections including sizing the branch line for the new appliance, installing a proper shutoff valve at the appliance location, making the connection with an approved flexible connector, and performing a pressure test before the appliance is placed in service. Con Edison also requires notification for new gas appliance connections before final connection to the meter.
