From structural rough carpentry to detailed finishes and specialty installations, JRB LLC delivers interior scopes with the coordination, craftsmanship, and accountability needed to keep projects moving.
We support commercial and residential projects across the Mid-Atlantic with a full range of interior services— including rough and finish carpentry, Division 8 openings, Division 10 accessories, Division 12 furnishings, appliance installation, and closeout support.
The behind-the-walls work that sets the job up for smooth installations and fewer field fixes.

Expert installation of building openings—where performance, security, and code compliance meet.
The essential finishing pieces that make a space functional, complete, and ready for occupancy.
Furnishing packages that complete the interior with a coordinated, finished look.
Professional installation of residential and commercial appliances, coordinated with the surrounding finishes.
We help teams cross the finish line with responsive support during final inspection and turnover.
A specialty of ours — from high-performance and high-security openings to fully accessible, code-compliant hardware.
We're experienced installing high-performance doors from leading manufacturers, including Kreiger Doors for sound, blast, and bullet resistance, and Overly Doors for high-security and sound transmission class (STC) applications.
We fit a wide range of hardware from Allegion, and we install and service high-security locking systems such as Kaba Mas X-10 and LKM (Lock Masters) 10K locks.
We ensure every opening is not only secure but also accessible — installing mechanical and electrified exit devices and LCN Automatic Operators that meet all ADA requirements.
Interior scopes often live at the intersection of schedule pressure, trade coordination, and high visibility. Our teams bring clear communication, disciplined field execution, and a quality-first approach that helps reduce rework and keep momentum through closeout.
Corporate interiors, hospitality, multi-family, healthcare, and institutional projects—especially where openings, hardware, and accessory packages require tight sequencing.
A single team that can own multiple interior scopes—reducing handoffs and simplifying scheduling.
