Detached homes, converted houses, and small commercial
In Bayside and Whitestone you are mostly in detached houses with accessible basements, exterior cleanouts, and yard space for a lateral excavation. Astoria and Ridgewood mean attached buildings where the only cleanout is in a shared cellar and a jetter hose has to run through somebody's apartment. Forest Hills adds co-op units where the building's plumber controls the risers and your scope stops at the fixture. Flushing brings storefront and restaurant work — grease lines, floor drains, and backflow devices that carry testing and filing requirements.
Those are four different businesses on one phone line. Which one the caller belongs to determines the equipment, the crew, and whether a permit or a licensed filing is part of the job.
