Nashua is New Hampshire's second-largest city and a major technology & defense hub. Enterprise Cleaning Corporation provides tailored janitorial, floor care, and day porter services for Gateway Hills, Route 3 tech parks, and corporate offices.

Built for Nashua
Commercial Cleaning Built for Nashua's Business Community
Nashua is New Hampshire's second-largest city, with a population above 90,000, and it sits at the southern edge of the state along the Route 3/Everett Turnpike corridor — close enough to the Massachusetts border to draw businesses that want New Hampshire's tax advantages without giving up easy access to the Boston metro area. The city is organized into ten distinct business districts, and its technology and office parks, including the Gateway Hills complex housing Nashua Technology Park and Nashua Office Park, are home to tenants like BAE Systems, Dell, Amphenol, and Benchmark Electronics — a strong concentration of defense contractors, technology firms, and corporate offices in one part of the city.
That tenant mix means Nashua facility managers are frequently responsible for buildings with security and compliance considerations that go beyond a standard office cleaning contract — defense contractors and technology firms often require background-checked cleaning staff and coordination around restricted-access areas, in addition to the appearance standards any corporate tenant expects.
Enterprise Cleaning Corporation has extended its Massachusetts service standards north across the border into Southern New Hampshire, with Nashua as a primary focus. We bring the same nightly janitorial, day porter, and floor care services — along with the same 97% client retention rate and owner-accessible service model — to Nashua's technology, defense, and corporate office tenants that we've built our reputation on throughout Central Massachusetts.
Crossing into New Hampshire doesn't change how we operate: the same crews, scheduling standards, and direct line to ownership that Massachusetts clients rely on extend across the border to Nashua. For technology and defense tenants at Gateway Hills, that also means we're able to coordinate around access restrictions and staffing requirements without treating them as a special exception.

View ServicesOur Process
How We Build Your Cleaning Plan
Every Nashua account starts the same way: a free, no-obligation walkthrough of your property with a member of our team, not a subcontractor or a franchise sales rep. We look at square footage, floor types, restroom count, tenant mix, and current pain points, then put together a written scope and price before any contract is signed.
Once a schedule is set, your account gets a dedicated crew rather than a rotating pool of subcontracted labor, so the same people learn your building, your supply closets, and your particular quirks — a security system that needs a specific arm-and-disarm sequence, a floor that scuffs easily, a tenant who works late. Consistency in staffing is one of the most requested — and least delivered — things facility managers ask for from a cleaning vendor, and it's built into how we staff every Nashua account from day one.
We check in regularly rather than waiting for a complaint, and because our ownership is directly reachable — not buried behind a franchise call center — issues get resolved in a conversation, not a ticket queue. That combination of a stable crew, a direct point of contact, and a willingness to actually show up when something needs attention is reflected in a 97% client retention rate across our full service area.
Every Nashua crew is fully insured and bonded, trained on the equipment and cleaning chemicals used on your property, and briefed on any building-specific access, security, or safety requirements before their first shift. If your Nashua property has a facility handbook, badge-in procedure, or vendor compliance requirement, we build our onboarding around it rather than asking you to work around us.
