Corporate espionage and competitive intelligence threats are real—and they're why more business owners are booking professional bug sweeps. If you're considering a counter-surveillance inspection for your office, understanding pricing and what to expect will help you make a smart decision.
Why Commercial Bug Sweeps Cost More Than Residential
Office spaces are fundamentally different from homes. They're larger, often multi-story, contain more electronic equipment, and feature more entry points, ventilation systems, and hidden infrastructure. A residential sweep might cover 2,000 square feet in a few hours; a commercial office on three floors with server rooms, conference areas, and executive suites can take an entire day or more.
Professional technicians must account for:
- Square footage and complexity – Larger spaces with multiple rooms, false ceilings, and mechanical systems require longer inspection times
- Equipment density – Offices contain phones, computers, printers, video conferencing systems, and WiFi infrastructure that all need testing
- Risk assessment – Higher-risk industries (legal, finance, consulting, biotech) warrant more thorough sweeps using advanced detection equipment
- Access requirements – Some areas may need security clearance or scheduled access, adding coordination time
Typical Pricing for Commercial Bug Sweeps
Most reputable counter-surveillance firms charge between $1,500 and $5,000 for a standard office bug sweep, depending on size and scope. Here's what you're usually paying for:
Basic sweeps (under 5,000 sq ft): $1,500–$2,500. This typically includes RF (radio frequency) detection, physical inspection of common areas, and a written report.
Mid-range inspections (5,000–15,000 sq ft): $2,500–$4,000. Adds more detailed equipment analysis, network security assessment, and testing of meeting rooms and executive spaces.
Comprehensive sweeps (15,000+ sq ft or high-risk): $4,000–$7,000+. Includes spectrum analysis, TSCM (Technical Surveillance Countermeasures) equipment, thermal imaging, network penetration testing, and a detailed vulnerability report.
Recurring contracts: Many offices negotiate quarterly or semi-annual sweeps at $800–$2,000 per visit for existing clients.
Some firms charge hourly rates ($150–$400/hour) instead, which works if you want flexibility but makes budgeting harder.
What Affects Your Final Cost
Location and travel time. If the sweep firm is based in your city, expect lower fees than if they're traveling from two hours away.
Urgency and scheduling. Emergency sweeps outside business hours cost more—sometimes 25–50% premiums.
Technology used. Firms with advanced spectrum analyzers, non-linear junction detectors, and network analysis tools charge more, but deliver better results.
Specific concerns. A general sweep is cheaper than a targeted investigation focusing on your phone lines, WiFi, or conference rooms.
Industry risk profile. Law firms, financial advisors, and biotech firms often pay more because threats are genuinely higher.
Red Flags in Low-Ball Quotes
If a company quotes you $500 for a 10,000 sq ft office, they're either inexperienced or cutting corners. Thorough sweeps take time—rushing through is worse than not sweeping at all. Legitimate operators won't finish a real commercial inspection in under 3–4 hours.
Ask potential providers for references, certifications (NFSTC or equivalent), and examples of reports from similar-sized offices. A detailed scope of work upfront protects both you and the technician.

Frequently Asked Questions
Q: How long does a typical commercial bug sweep take? A: Plan for 4–8 hours depending on office size and complexity; larger or high-risk facilities may require a full day or multiple visits.
Q: Will a bug sweep detect hidden cameras in bathrooms or locker rooms? A: Yes, professional sweeps use non-linear junction detectors and thermal imaging to find concealed cameras, though a reputable firm should clarify privacy boundaries and legal compliance before searching sensitive areas.
Q: Can I do a bug sweep myself with a cheap RF detector? A: Consumer RF detectors miss many surveillance methods and produce false positives; professional-grade TSCM equipment, operator experience, and liability insurance justify hiring a licensed firm.
