Harlem's housing stock is brownstones and pre-war apartment buildings — late-1800s and early-1900s construction, much of it now being gut-renovated, converted back to single-family, or reconfigured into new layouts. Buildings of that era were built and re-finished with asbestos-containing materials for decades, and a gut renovation or conversion disturbs nearly all of them.
Clear Advisory has completed recent project work in the neighborhood, including surveys ahead of renovation. If you're planning work on a Harlem property, the survey belongs at the front of the schedule: inspections are scheduled within 1–2 days, and lab results typically return in about 24 hours.
Common Asbestos Materials in Harlem Brownstones and Pre-War Buildings
- Pipe insulation on heating runs in cellars and throughout older steam systems
- Plaster and joint compound throughout pre-war interiors
- Vinyl floor tile and mastic, often layered over original flooring from successive renovations
- Boiler insulation in older heating plants
- Roofing materials — felts, flashing cement, and coatings on flat roofs
- Transite panels and cement board around boilers, panels, and shafts

FAQ
I'm gut-renovating a Harlem brownstone. When do I need the survey? Before demolition starts and before your DOB filing goes in. A gut renovation disturbs the full list of suspect materials — plaster, flooring, pipe insulation, roofing — so the survey should cover the whole work area, and the ACP-5 is filed in support of your DOB application.
We're converting a brownstone back to a single-family home. Does that change anything? The survey requirement follows the work, not the end use. A conversion scope typically opens walls, re-routes plumbing and heating, and redoes floors — the same disturbance as any gut renovation — so the building is surveyed the same way, before the filing.
How much does a Harlem survey cost? From $750 for the site visit, plus lab analysis per sample. A full brownstone samples more materials than a single apartment, so the total follows the scope — you'll know the sample count before the lab work runs.
How fast are results? Inspections scheduled within 1–2 days; lab results in about 24 hours. Most filings are ready within days of the call.
What if asbestos is found mid-renovation instead? Work in the affected area has to stop until the material is dealt with under the asbestos rules — licensed abatement, DEP notification, then work resumes. A survey up front is how that surprise gets priced and scheduled instead of stopping the job.
