Diversified Site Services LLC specializes in comprehensive facility maintenance and construction services for federal institutional campuses, with deep expertise in plumbing, heating, and air-conditioning systems; landscaping and grounds maintenance; and commercial building construction. The company delivers turnkey solutions for HVAC repair and replacement, water and sewer infrastructure upgrades, fire hydrant installation, and full-scale groundskeeping—including irrigation, turf management, and seasonal landscaping—ensuring operational readiness and compliance with federal facility standards. Their technical proficiency spans integrated building systems, utility line construction, and preventive maintenance protocols tailored to high-traffic VA and DoD environments, with a demonstrated ability to execute complex, mission-critical projects under strict regulatory and safety frameworks.

Their vertical specialization lies in maintaining and upgrading aging VA healthcare and administrative facilities, where seamless coordination of mechanical, civil, and hardscape systems is essential. As a Service-Disabled Veteran-Owned Business headquartered in Merrimack, New Hampshire, the company leverages its certification to meet federal small business goals while maintaining a focused operational footprint across the Northeast. Their structure supports agile, on-site project execution with a commitment to veteran-led workforce development and government compliance standards.
