Quick answer
Mold work in Jackson Heights is mostly apartment work: prewar garden co-ops and walk-ups where leaks travel along old risers, bathrooms that have not been opened in decades, and basement units that took on water in heavy storms. We trace the water, contain the work inside the unit, remove the growth and dry, then hand the board, the managing agent or the landlord the written scope and photos they ask for.

What drives mold in Jackson Heights buildings
The core of Jackson Heights was built as garden apartments. The Queensboro Corporation put up eight block-long garden apartment complexes between 1920 and 1925, and Linden Court, opened in 1919, was the first it sold under a cooperative plan. Many of those buildings are still co-ops, so a mold job involves a board and a managing agent as well as the owner.
It is also a large, rent-regulated neighborhood. In 2009 Jackson Heights had about 188,000 residents, 52.7 percent of its rental units were rent-regulated, and 15.3 percent of its homes sat inside a historic district. Old buildings with long-term tenants mean plumbing and windows that have not been opened in a long time.
Basements are the other risk. During Ida, most of the city's overnight deaths were in Queens basement homes, in neighborhoods including Woodside, next door. Below-grade units here can take on storm water fast, and mold follows within a day or two if they are not dried.

Working in garden co-ops
Before work starts, we send the managing agent the scope, the schedule and the plan for protecting the hallway, stairs and courtyard path. Many garden buildings have no elevator, so we bag and seal materials inside containment and carry them out through a cleaned route.
When the water comes from a riser or another unit, we document it with readings and photos so the right party can repair it. In buildings with 10 or more units, where the city requires separate companies above 10 square feet, we take either the assessment role or the removal role.

Interior mold work is generally unaffected; exterior changes such as windows can need approval.
