What Wohl Diversified Services does

Wohl Diversified Services (legal entity Lawrence B. Wohl, Inc.) is a fourth-generation, family-owned specialty trade contractor headquartered in Port Chester, New York, providing spray-applied building envelope services across the New York City and Tri-State region. Founded in 1961 as a union painting and decorating firm, the company has evolved into a multi-trade contractor organized around four core service categories: acoustical finishes (K-13, SonaSpray, SonaKrete, Cafco Sound-Shield), sprayed fire-resistive materials or SFRM (Monokote, Cafco Blaze-Shield, Pyrocrete) and intumescent fire-resistive materials or IFRM (Albi Clad, Cafco SprayFilm, Carboline, Hilti), thermal insulation via spray polyurethane foam and fiber-based systems (Carlisle, Huntsman, NCFI, Monoglass, Sonoglass), and firestopping.

The company operates as an authorized/premier applicator for nine major product manufacturers (International Cellulose, Isolatek, GCP, Carboline, Carlisle, Huntsman, NCFI, Albi, and Hilti), with UL DRI-certified personnel on staff and active leadership in industry bodies including the NFCA and PSFC of Greater New York. Notable completed work includes fireproofing and acoustic finishes at the National September 11 Memorial & Museum, Met Museum Rockefeller Wing renovation, Grand Central Terminal / MTA Eastside Access, Clear HQ, WWE HQ, and Great Point Studios.

Wohl generates revenue through project-based specialty contracting services, winning work through competitive bidding, manufacturer referrals, and long-standing relationships with major New York general contractors including Turner, Skanska, Suffolk, STO Building Group, AECOM Tishman, Clune Construction, and Whiting Turner. Pricing is custom-quoted per project based on scope, materials, and labor; no standard pricing tiers are publicly disclosed. The company is led by President Rachel Girsch and Executive Vice President Bryan Girsch, with Jonathan Wohl serving as Chairman Emeritus and David Dal Pra as Director of Operations.

Core offering

Wohl Diversified Services is a specialty trade contractor that applies spray-applied fireproofing (SFRM and IFRM), acoustical finishes, spray polyurethane foam and fiber-based thermal insulation, and firestopping products on commercial construction projects. The firm operates as an authorized/premier applicator for leading manufacturers (GCP, Isolatek, Carboline, Carlisle, Huntsman, NCFI, Albi, Hilti, International Cellulose) and delivers these services as a subcontractor to general contractors and construction managers across New York City and the Tri-State area.

Product overview

Wohl Diversified Services (Lawrence B. Wohl, Inc.) is a specialty contracting firm offering a unified portfolio of spray-applied building envelope services organized into four core categories: Acoustical Finishes, Fireproofing (SFRM and IFRM), Thermal Insulation (Spray Foam and Fiber-Based Systems), and Firestopping. The Acoustical Finishes suite includes K-13, SonaSpray, SonaKrete, and Cafco Sound-Shield, which collectively address noise reduction, reverberation control, and aesthetic finishing. Fireproofing services are delivered through two systems — SFRM products (Monokote, Cafco Blaze-Shield, Pyrocrete) for concealed structural steel with ratings up to 4+ hours, and IFRM intumescent coatings (Albi Clad TF, Albi Clad 800, Cafco SprayFilm, Carboline, Hilti) for exposed architectural steel with smooth paintable finishes. Thermal Insulation includes spray polyurethane foam (Carlisle SealTite, Huntsman Heatlok, NCFI InsulBloc) offering R-values up to R-7 per inch, and fiber-based systems (Monoglass, Sonoglass) combining dual thermal and acoustic control. Firestopping services round out the offering for code compliance. The company operates as a single-service contracting model — all offerings are professional application services performed by trained installers using manufacturer-branded products, rather than a software platform.
