Managed IT for Construction Companies in NYC
New York construction runs on bids, schedules, and a network of subcontractors that balloons with every job. We keep the technology side boring for NYC contractors — Microsoft 365 managed, ransomware kept out, and, when off-the-shelf software doesn't fit the trade, we build what does.
The short answer
NetSys provides managed IT to New York City construction companies and trades: full Microsoft 365 management, cybersecurity built for firms whose subcontractor network multiplies their exposure, ransomware defense and recovery planning, and custom-built software where the trade's workflow demands it. Month to month, with engineers on-site in the five boroughs from our Brooklyn headquarters.
A government-bid contractor secured; a trade's platform built
The first client is a NYC construction company that bids substantial New York City government work — fifteen full-time employees whose subcontractor network can exceed two hundred people depending on the job. The second is a New York City plumbing company that needed better client communication than any off-the-shelf tool gave them.
For the contractor, the fear was ransomware: a company that lives on bid deadlines and government relationships cannot be down, and every subcontractor connection is another door. The plumbing company's problem was different — clients in the dark about when a tech was coming, and invoicing that didn't fit how the work actually flows.
What NetSys did
- Contractor: full management of the Microsoft 365 environment
- Contractor: a cybersecurity plan built around a workforce of 15 employees plus a rotating network of 200+ subcontracted agents
- Plumbing company: a custom CRM that emails and texts clients live updates — which tech is coming, when, and for what service
- Plumbing company: a purpose-built invoicing platform, plus a one-time security overhaul of their Microsoft 365 environment
The results, as measured since onboarding
- Contractor: zero security incidents and 100% uptime since NetSys came on
- Plumbing company: client communication and invoicing running on a platform built for exactly how they work

Built for how NYC construction actually works
City work means government bids with security questions attached, jobsites across the boroughs, and a subcontractor roster that changes monthly. The IT that supports it has to be as mobile as the crews and as careful as the bid paperwork — and when a trade needs software shaped like its workflow, we build it rather than bending the business around an app.
Everything else about how we serve the area — coverage, on-site cadence, and the honest answer about where our office is — lives on our New York City location page.
Construction Companies in New York City: FAQs
Why is a construction company a ransomware target?
Because downtime is leverage. A contractor mid-project has schedules, draws, and government deadlines that make every locked file expensive — and a network of subcontractors that widens the attack surface with every job. The contractor on this page has run at zero incidents and 100% uptime since we took over its security and Microsoft 365 environment.
Can you handle the security requirements on government bids?
That is part of why this client engaged us. Public work increasingly asks bidders to demonstrate real security posture, and the honest way through those questions is controls that actually exist: managed Microsoft 365, monitoring, and a recovery plan. We keep the environment in a state where the answers are simply true.
Do you build custom software for trades?
When the workflow demands it, yes. The plumbing company on this page got a custom CRM that keeps clients updated by text and email — who's coming, when, for what — plus an invoicing platform shaped to their jobs, and a security overhaul of their Microsoft 365 alongside it. Off-the-shelf first; custom when the fit is genuinely wrong.
