What Installation Services Llc does

Installation Services LLC is a privately held, Class A licensed general contractor founded in 2000 and headquartered in Dumfries, Virginia, with additional offices in Fredericksburg, Virginia and Pendleton, North Carolina. The firm delivers construction, renovation, and facility maintenance services across three primary segments: residential homeowners (specializing in basement finishing, plus HVAC, electrical, plumbing, painting, flooring, doors, decks, and kitchen/bath remodeling); commercial clients (tenant improvements, build-outs, renovations, design-build, and construction management for projects up to $1 million); and federal government and Department of Defense customers served via GSA Schedule 561210FAC (GS-21F-0038Y) with 24/7/365 facilities operations, maintenance, and ancillary repair services across multiple states.

The company's underlying technology stack is modest: a web-based Computerized Maintenance Management System (CMMS) for tracking preventive maintenance and service calls, supplemented by ISO 20000 framework project management methodology. All residential and most commercial work is self-performed by in-house licensed and, where required, security-cleared personnel — no subcontractors are used for residential projects. This in-house model is reinforced by PMP-certified project managers and master technicians across trades.

The business operates on a hybrid revenue model: project-based, one-time revenue for residential and commercial construction jobs (priced via quote and free in-home estimates), alongside managed-services contracts with federal and DoD clients for ongoing facility operations and maintenance. Marketing combines direct sales (website quote requests, phone inquiries), HomeAdvisor and Angie's List listings for residential leads, and GSA Advantage plus industry association presence (NAGC, NARI) for government procurement. The company holds multiple set-aside certifications (HUBZone, WOSB, EDWOSB, DBE, SWaM, SLBE) that confer preferential access to federal contracting opportunities, and reports 165+ separate contracts across federal and DoD clients.
