Best construction security companies in the US (2026)
Finding the best construction security company anywhere in the US comes down to one question that a search results page can never answer: can this agency actually keep a half-finished site from being stripped of copper, tools, and equipment over a long weekend? Jobsite theft is a national problem — the Sun Belt boom corridors of Florida and Texas, the dense vertical builds along the coasts, the master-planned tracts of the Mountain West, and the industrial and plant work across the Midwest all feed a billion-dollar resale market in stolen copper, lumber, appliances, and compact equipment. The firms worth shortlisting are the ones that understand construction risk in their market, not generic patrol outfits that treat a jobsite like a parking lot.
Calvis is not a security agency and does not hold a security license. What Calvis does is vet construction-focused agencies in metros across the country, confirm each one's insurance and state licensing, and match your project to the agency that fits the site, the schedule, and the budget — whether that is a downtown high-rise on the East Coast, a custom-home corridor in the Sun Belt, or a plant expansion in the industrial Midwest. Instead of cold-calling names and verifying credentials yourself, you get a shortlist of independently-licensed agencies that have actually staffed jobsites like yours, with the paperwork already checked.

Construction security across the US
Construction site security in the US tracks the building cycle, and that cycle is concentrated in a handful of corridors: the Sun Belt growth markets of Texas, Florida, Arizona, and the Carolinas, where master-planned communities and commercial product go up fast across wide, lightly-trafficked sites; the coastal metros, where vertical builds pack active sites side by side with valuable rough-ins exposed overnight; and the industrial Midwest, where automotive-plant and warehouse construction spread equipment across footprints too big for a single post. Across all of them, copper, power tools, lumber, appliances, and compact equipment are the items that move on the resale and scrap market, making after-hours and weekend coverage the core need. Weather adds regional pressure — hurricane shutdowns in the Southeast and winter stoppages in the North both leave structures exposed with crews off-site for days. Because risk and labor cost vary so much from one metro to the next, the right coverage plan — fixed post, mobile patrol, camera towers, or a mix — rarely looks the same in two markets.
Matched to
what you need.
Construction security spans these construction site security specialties. Tell us what you need and we match you to vetted agencies built for it, in your market.
Overnight & Weekend Jobsite Coverage
Dedicated officers hold the site through the hours when crews are gone and theft risk peaks, from evening lockup straight through to the morning gate opening. Coverage is built around the construction calendar, with extra attention on the long holiday, storm-prep, and winter-shutdown weekends when sites across the country sit empty the longest.
- Ideal for
- Active builds of any type — vertical or horizontal — that go dark at night and over weekends with valuable rough-ins on site.
- Coverage
- Nationwide — Sun Belt, coastal metros, and Midwest plant corridors
Equipment & Material Theft Prevention
Officers focus on the targets that actually move on the national resale and scrap market — copper wire, power tools, lumber bundles, HVAC and appliance units, and compact equipment left on site. They control the laydown yard, log who pulls material, and watch the access points where stripped copper and stolen tools usually leave a jobsite.
- Ideal for
- Projects with copper rough-ins, tool cribs, appliance and fixture stockpiles, or rented equipment parked overnight.
- Coverage
- Nationwide — highest demand in high-theft Sun Belt and urban-infill markets
Access Control for Trades & Deliveries
A posted officer at the gate verifies subs, delivery drivers, and inspectors against the day's schedule and keeps a running access log. On congested urban blocks and fast-moving commercial pads alike, that single checkpoint stops piggybacking, keeps unbadged people off the structure, and gives the GC a clean record of everyone on site.
- Ideal for
- Dense urban sites and commercial builds with heavy trade turnover, just-in-time deliveries, and limited staging room.
- Coverage
- Nationwide — coastal high-rises and Sun Belt commercial corridors
Mobile Patrol & Camera-Tower Monitoring
Marked patrol units sweep multiple sites on a randomized schedule while solar camera towers cover perimeters and blind corners between passes. This pairing is the practical model for sprawling master-planned tracts and wide plant footprints where a single fixed post cannot see the whole site.
- Ideal for
- Large-footprint or multi-lot projects, and owners running several smaller sites who want one coordinated coverage plan.
- Coverage
- Nationwide — built for low-density Sun Belt and Midwest plant sites
Fire Watch for Hot Work & Welding
Trained fire watch officers stand by during welding, cutting, and roofing torch work, and hold the post through the required cool-down window after the crew leaves. They keep an extinguisher path clear and a written log that satisfies the GC, the insurer, and the local fire marshal.
- Ideal for
- Structural steel, MEP, and roofing phases with permitted hot work, or sites running on a temporarily impaired fire system.
- Coverage
- Nationwide — wherever local fire codes require a posted watch
A real bar,
not an ad auction.
Every agency clears the same four checks before it can take construction site security work — in every market we cover.
State licensing verified
Security licensing is state-by-state. Every agency is verified against its own state's requirements before it can take work.
Active insurance on file
Current general-liability (and where applicable, workers' comp) coverage is verified, not assumed.
Background-checked officers
Agencies field licensed, background-checked guards — the people who actually show up on site.
Tracked reliability record
Shift-reliability is measured on the platform. Agencies that no-show or slip on coverage are removed.
Construction security companies by city
Common
questions
Calvis screens each agency before it ever reaches your shortlist, no matter the metro. That means confirming an active security license with the agency's own state regulator, checking general liability and workers' comp coverage, and reviewing the agency's track record on actual construction sites rather than retail or residential posts. Only agencies that clear those checks get matched to projects, so the vetting standard is the same whether your site is in Miami, Dallas, Phoenix, or Detroit.
Rates vary by metro — unarmed officers generally run about $25-55/hr and armed about $45-95/hr nationally, lower in the South/Midwest and higher in coastal metros. Pricing also shifts with shift length, site risk, and how quickly you need coverage, and camera towers and mobile patrol are usually quoted separately — often cheaper than a fixed post on a large or low-traffic site. Calvis collects comparable quotes from vetted agencies in your market so you see the real local range instead of one inflated number.
The agencies are licensed, not Calvis. Security licensing is regulated state by state, and each agency holds its own credential through its state body — for example the Florida Department of Agriculture and Consumer Services (FDACS), the Texas Department of Public Safety (DPS), the California Bureau of Security and Investigative Services (BSIS), or the New York Division of Criminal Justice Services (DCJS). Calvis verifies those state credentials before matching an agency to your project. Calvis itself is a vetting and matching service; it does not hold a security license or employ guards.
Yes. National and regional builders rarely have one agency that is licensed and staffed in every market they operate in, so Calvis matches a separately-vetted, state-licensed agency in each metro where you have a site and coordinates them under one point of contact. You get consistent coverage standards — overnight posts, access control, theft prevention, and fire watch — across a multi-site program without having to qualify a different agency in every city yourself.
Calling around means trusting each agency's own sales pitch and verifying its license and insurance yourself, one market at a time. Calvis has already vetted construction-focused agencies in metros across the country, so you get a shortlist of qualified, state-licensed options, comparable pricing, and a faster path to coverage — which matters when a site needs guards before the next weekend, not next month, and even more when you are standing up several sites at once.
