Ner Construction Management

What Ner Construction Management does

NER Construction Management, Inc. is a Wilmington, Massachusetts-based specialty contractor founded in 1983 by Richard Sylvester Sr. and Richard Sylvester Jr. as a father-and-son masonry firm, now in its third generation of family ownership under President Nick Sylvester. The company provides four core service lines: new construction masonry and stonework, building restoration and cleaning (including facade repair, epoxy injection, sandblasting, and chemical cleaning), waterproofing and sealing (coatings, caulking, air vapor barriers, and seamless monolithic liquid-applied membranes), and stone services (interior and exterior natural and cast stone). Its operational backbone is a 50,000 square foot headquarters facility on a three-acre yard in Wilmington, supporting in-house mechanics, a large vehicle fleet, and on-site material storage that enables rapid mobilization to project sites.

NER's work is concentrated on historically and architecturally significant structures across New England, with a project portfolio that includes the Fenway Park 1912 Seating Bowl, the MIT Ziggurat, multiple Harvard and Yale buildings, the New England Conservatory's Jordan Hall, the Massachusetts State House, Encore Boston Harbor, and the Langham Boston Hotel. Differentiated technical methods include Engineered Temporary Protection (ETP) tent enclosures enabling off-season and multi-shift work, hydro-demolition for concrete overlay repairs, terra cotta cornice remolding and duplication, and specialized large-format porcelain panel installation. The firm has accumulated more than 20 preservation and trade awards over 40 years, including recognitions from the Boston Preservation Alliance, Preservation Massachusetts, the National Trust for Historic Preservation, and the International Masonry Institute.

NER operates as a project-based subcontractor and direct vendor, with no disclosed external funding, no parent company, and no subsidiaries. Revenue is generated through project-by-project contracts awarded via three channels: subcontracting to general contractors (Lee Kennedy, Bond Brothers, Suffolk Construction, Tishman/AECOM), direct engagement with institutional owners (Harvard, MIT, Boston Red Sox, Analog Devices, Commonwealth of Massachusetts), and architectural specifications from preservation specialists. The customer base spans education, professional sports, hospitality, commercial real estate, and government, all within a single-region New England footprint. Pricing is custom-quoted per project with no standard tiers or recurring-revenue model, and the firm employs between 101 and 250 people with craft crews averaging 20 years of industry experience.
