Spray Foam Insulation in Port Richmond, NY

Spray foam insulation in Port Richmond often means bringing a 19th-century house up to modern comfort. Wikipedia describes Port Richmond as a former independent village and one of the oldest neighborhoods on the island, a transportation and industrial center in the 1800s that later became a largely blue-collar residential area. An old account quoted on the page describes dwellings that ranged from mansions to quiet cottages on wide, tree-shaded streets.

Heberton Avenue and older streets

Heberton Avenue is known for handsome old houses. The house at 121 Heberton Avenue, built around 1859-61, is a designated New York City landmark and a rare surviving example of a Rustic-style picturesque villa. Houses of that era and the frame houses that followed share traits we plan around: balloon framing, plaster walls, old wiring in places, and attics that were never meant to be insulated.

Rentals and multifamily houses

Wikipedia's census summary for Port Richmond's tabulation area shows 56.0% of occupied housing units are renter-occupied. Many buildings are two- and three-family houses. For owners, the jobs that pay back fastest are usually air sealing the attic, foaming the rim joist and filling empty exterior walls with dense-pack cellulose. These reduce drafts in every unit without major disruption to tenants.

Near the Kill Van Kull

Port Richmond sits on the Kill Van Kull, where Hurricane Sandy produced a storm surge of 9.56 feet above normal tide near the island's northern tip, according to Wikipedia's account of the storm. Lower blocks near Richmond Terrace can have damp basements. We check for moisture before insulating any lower level, and we choose closed-cell foam or other moisture-tolerant materials below grade.

Code and comfort

The 2025 NYC Energy Conservation Code sets Climate Zone 4A for the city and lists R-49 for ceilings and R-15 continuous for basement walls. An older house will not match new construction, but sealing and filling the main gaps gets most of the comfort gain at a fraction of a gut renovation.
