We serve all these areas too.
A mansion-to-apartment conversion in Clinton Hill typically involves new vertical supply stacks from the basement water main to each floor, new drain stacks per the unit layout (which may mean cutting through original stone or concrete floors), and rough-in for each new bathroom and kitchen. Buildings from the 1870s–1880s often have original iron supply and cast-iron drains that need to be assessed — some sections may be reusable, but most are replaced as part of the conversion scope. DOB permits and plumbing inspections are required; we handle the full permit filing and inspection process.
Adding a bathroom to an apartment in a Clinton Hill steam-heated building is a plumbing rough-in project, not a heating project — the bathroom has its own cold water supply, hot water supply, drain, and vent requirements that are independent of the steam system. The constraint is drain routing: the new drain needs to connect to the existing stack with proper pitch. We can assess whether the stack location and floor construction allow a connection and provide a rough-in estimate.
