Park Slope’s 40-block Historic District is one of the largest landmarked residential areas in New York, and most homes here reflect it — brownstone and limestone rowhouses with original stoops, parlor floors, bay windows, and decorative woodwork that’s often over a century old. Many of these homes have been divided into garden-floor rentals, parlor-floor units, and upper duplexes, each with its own quirks. Our cleaners are trained to handle original hardwood, mantels, and built-ins with care, and we’re used to navigating stoop entries and narrow brownstone stairwells. For pre-war co-ops along Prospect Park West and newer condos on 4th Avenue, we coordinate with building supers and provide a COI when a board requires one. Whether you’re in a single-family brownstone near the park or a garden-floor rental off 7th Avenue, every clean is built around your specific floor plan and finishes.
