Construction site security from GRDX covers job sites and vacant properties overnight and on weekends, when theft, vandalism and trespass are most likely. Officers run fixed posts or GPS-verified patrol checks and file time-stamped photo reports, serving builders and owners across Northern Virginia, D.C. and Maryland.
What gets stolen from construction sites?
Anything that can be sold quickly: copper, wire, power tools, generators, fuel and small equipment.
Thieves often scout during the day, then return after dark with a truck. Appliances get taken right after delivery to a new home. Vandals tag fresh drywall. Kids climb onto scaffolding on a Saturday. Each of these lands on the schedule and the budget.
Losses also hit the schedule. A stolen generator can stop a crew for a day while someone rents a replacement, and stripped copper means an inspection gets pushed back.
- Copper pipe and wire pulled from framed units
- Tools from open trailers and gang boxes
- Appliances delivered before closing
- Fuel siphoned from equipment
- Graffiti and broken windows on finished work
Fixed post or patrol checks for a job site?
Large sites with equipment staged overnight usually justify an officer on site. Smaller sites and scattered lots often do well with patrol checks several times a night.
| Fixed officer | Patrol checks | |
|---|---|---|
| Coverage | Continuous through the night | Several visits per shift |
| Best for | Big sites, staged equipment, deliveries | Small sites, multiple lots, vacant buildings |
| Records | Shift log with photos | GPS-verified stops with photos |
Vacant property checks
Vacant property checks confirm that an empty building is still locked, dry and unoccupied.
Empty retail spaces, foreclosed homes and buildings waiting on permits all draw squatters and scrappers. An officer checks doors and windows, looks for signs of entry, and photographs anything that changed since the last visit. Lenders, owners and insurers can see the history.
Entry points
Doors, windows and boards checked each visit.
Signs of occupancy
Bedding, trash, lights or new locks.
Damage
Leaks, broken glass and graffiti photographed.
Working with your superintendent
The officer reports to the person running the job, not only the office.
Your super knows when the crane is idle, when concrete pours run late and when appliances arrive. We agree on gate codes, lock-up times and who to call when something is found. If a delivery is due Friday afternoon, the officer can be on site when it lands.
Officers also note safety hazards they spot on rounds, like an unsecured ladder against scaffolding or a hole left uncovered, so your super can fix it before the crew arrives Monday.
Security needs change with each project phase
Early sitework is about equipment and fuel; finish work is about copper, appliances and fixtures.
During grading and foundations, the expensive items are machines parked overnight. Once framing goes up, plumbing and electrical rough-in bring copper onto the site. Near closeout, cabinets, appliances and HVAC units arrive, and so does the risk of someone walking a stove out the back door of an unsold home.
We set coverage for the phase you are in and suggest changes as the job moves. A builder with a townhome community in Prince William might start with patrol checks and add an overnight officer when appliances land.
Standards on every site, and getting a quote
Officers are licensed and verified before they are scheduled. Supervisors inspect posts. Reports are time-stamped with photos and patrol stops are GPS-verified. A supervisor answers 24/7, and any officer can be replaced on request.
Builders also ask about liability. Our officers observe, document and call police; they do not chase intruders across a site full of open trenches and rebar.
Call (833) 350-4739 or send the site address. We reply within one business day, visit the site, and send a written proposal sized to the phase of the project. Coverage can grow when units go up and stop when the last one closes.
Questions
How much does construction site security cost?+
Price depends on hours, fixed post versus patrol, and whether the officer is armed. We quote after a site visit so the number reflects your actual site.
Can you cover weekends only?+
Yes. Many builders book Friday evening through Monday morning, when sites sit empty the longest.
Do you check vacant homes and storefronts?+
Yes. Vacant property checks cover doors, windows and signs of entry, with photo reports after each visit.
What happens if an officer finds someone on site?+
The officer follows the procedure agreed with you, which usually means contacting police and your designated contact, then documenting everything.
Do you cover sites outside Virginia?+
Yes, in D.C. and Maryland, including Montgomery, Prince George's and Baltimore.
Do you increase coverage near project closeout?+
We can. Many builders add hours when appliances and fixtures are installed, then end coverage once units are sold and occupied.
