Between 2017 and 2026, Lou Rubino inspected 20 homes in Park Slope. The Slope's brownstones went up mostly between the 1880s and the 1910s, and buying one means buying a hundred-plus years of decisions — original, Victorian-era craftsmanship and every owner's project since, stacked four storeys high.

The cellar is the honest end of the house. Down there the original joists, the notches and patches of every plumbing era, and the beams that have carried it all along are simply visible — nothing has been decorated. Lou spends real time in Park Slope cellars because the floors above only make sense once you have seen what holds them.
The top floor is the other truth-teller. Under the roof, the rafters record every leak the ceilings have long since been painted over — and with a curb-invisible flat or shallow-pitch roof above, that record is usually the only warning you get. A finished top floor with no attic access is precisely the "not observed, and here is why" case New York requires the report to spell out.

All three photographs are from Lou's own Park Slope inspection reports, chosen because they show a building component and nothing that identifies a property or an owner.
Interior finishes are read as evidence, not decoration — a crack pattern, a stain edge or a new patch of paint each say something about what the building has been doing. See how findings are documented.
A flat roof hides everything from the street: membrane seams, patches, drainage and parapet condition. Patching is normal maintenance — the question a report answers is whether the membrane still has a working life. How roofs are examined and reported.
Supply plumbing is judged by material and era — and by the small evidence at the joints. Corrosion and mineral tracks at connections show slow weeping long before a failure. Moisture evidence, explained.
Meters, regulators and gas piping are checked visually and, where warranted, with instruments — outdoor equipment in salt air earns a closer look. How a building is metered is also part of what you are buying. The licence behind the inspection.
Siding, trim, masonry and parged walls are the building's raincoat, and cracks or failed mortar can give water a way in. The report documents their location and pattern so the right contractor or specialist can evaluate them when warranted. Where water gets in, explained.
Chimney crowns, caps and screens are the cheap parts that protect the expensive parts. Cracked crowns and missing screens let water and animals into a flue, and the damage below can run for years unseen. What happens when part of a system cannot be seen.
All photographs are from Lou's own inspection reports for jobs in this area, screened so nothing identifies a property or an owner.
Lou covers Long Island, the five boroughs and Westchester from his base in Wantagh, and the archive behind these pages shows where that work has actually concentrated.
