We serve all these areas too.
In Ridgewood's pre-war two-families, the most common cause is galvanized steel supply pipes that have narrowed internally from 90-plus years of mineral buildup — a 3/4-inch line can be down to 1/4-inch inside without showing any exterior damage. Low pressure on upper floors is usually the first sign. A pressure test and pipe inspection will confirm whether repiping is needed, which in most Ridgewood two-families means replacing the galvanized risers with copper or PEX.
Banging in a one-pipe steam system is almost always caused by water pooling in a pipe that's slightly out of pitch, or a failed steam trap holding condensate in the radiator. Both are fixable without replacing the system. We re-pitch the return lines or replace the air vents and traps — a repair job in most Ridgewood two-families, not a full boiler overhaul.
