Security Diligence, LLC is a security services and consulting company based at 3115 St. Lawrence Ave in Reading, Pennsylvania. The company operates from the eastern edge of the Reading area, along the St. Lawrence Avenue corridor that connects the city with the surrounding Berks County municipalities of Exeter Township, St. Lawrence and Lower Alsace. Inquiries are handled by phone at (484) 509-0320.
The firm's name reflects a concept central to the field it works in. In security and risk management, diligence refers to the structured process of examining a property, an organization, a transaction or an individual closely enough to understand what could go wrong and what reasonable steps would reduce that possibility. Companies working under this model tend to emphasize assessment and planning as much as the physical or technical measures that follow from them.
Areas of Work
Security firms operating in the Reading and Berks County market typically serve a mix of commercial, institutional, residential and individual clients. Work in this sector commonly falls into several broad categories:
- Security assessments and surveys, in which a site is reviewed for vulnerabilities involving access points, lighting, sightlines, alarm coverage, key control and the movement of people through a building or property.
- Consulting on security programs, including written policies, emergency and evacuation planning, workplace violence prevention, visitor management and incident response procedures.
- Investigative services, which can range from background research and due diligence on prospective business partners or employees to fact gathering that supports insurance claims, litigation or internal workplace matters.
- Guard and patrol coordination, covering staffed posts at commercial properties, construction sites, industrial facilities, special events and residential communities.
- Executive protection and secure transportation for corporate travelers, visiting dignitaries, healthcare professionals and individuals facing specific threats.
- Training and education, including safety awareness sessions for staff, de-escalation instruction and preparation for the certifications Pennsylvania requires of certain security personnel.
Not every firm provides every one of these services, and prospective clients are generally best served by describing their situation directly to the company and asking which of its capabilities apply. Because security work is highly situational, a short conversation about the property, the concern and the timeline usually reveals more than a general service list can.
Regulatory Context in Pennsylvania
Anyone evaluating a security provider in Pennsylvania benefits from understanding how the industry is regulated, since the rules differ from those in many other states. Private investigative work is governed by the Private Detective Act of 1953, which is administered not by a statewide licensing board but by the Court of Common Pleas in each county. A licensed investigator in Berks County holds that license through the county court, and the statute sets minimum experience requirements that generally involve prior investigative work in law enforcement or with a licensed agency.
Security officers who carry a lethal weapon in the course of their duties must be certified under Act 235, the Lethal Weapons Training Act, which is overseen by the Pennsylvania State Police. Certification involves classroom instruction, a written examination, firearms qualification and a psychological screening, and it must be renewed periodically. Armed and unarmed posts therefore carry different staffing requirements and different cost structures, a distinction worth raising early in any discussion about coverage.
Clients arranging ongoing services should also expect to review proof of general liability insurance, and in the case of staffed posts, workers' compensation coverage. Reputable providers supply this documentation without being asked twice.
Location and Service Area
Reading is the seat of Berks County and the anchor of a metropolitan area of more than 400,000 residents. Its economy includes manufacturing, food processing, logistics and distribution, healthcare and a growing number of warehouse and fulfillment operations along the U.S. Route 222 and Interstate 78 corridors. Each of these sectors generates its own security requirements: perimeter control and loss prevention at distribution centers, access management and de-escalation training in healthcare settings, equipment and material protection at construction sites, and after-hours coverage for offices and retail spaces.
The St. Lawrence Avenue location places the company near the U.S. Route 422 interchange, which provides direct access west toward Reading and Wyomissing and east toward Pottstown, Collegeville and the Philadelphia suburbs. Providers based in this part of Berks County are commonly positioned to serve clients throughout the county as well as into Montgomery, Chester, Lancaster, Lehigh and Schuylkill counties, depending on the nature of the assignment. Assessment and consulting work, in particular, often extends well beyond the immediate area, since the deliverable is a report and a plan rather than a continuous physical presence.
What to Expect From an Engagement
Security consulting engagements usually begin with an intake conversation, followed by a site visit or records review, and conclude with findings and recommendations. Recommendations are ordinarily tiered, separating measures that address immediate exposure from longer term capital improvements such as camera systems, electronic access control or structural changes to entrances and parking areas. A useful report distinguishes between what a client must do to meet a legal or insurance obligation and what is simply advisable.
Staffed security arrangements work differently. These are typically governed by a written agreement that specifies post orders, hours of coverage, reporting procedures, escalation contacts and the circumstances under which officers contact local police. Clarifying these details in advance prevents the most common source of dissatisfaction in the industry, which is a mismatch between what a client assumed officers would do and what they were actually authorized to do.
Investigative assignments generally require a clear statement of the question to be answered, an agreed budget and an understanding of how findings will be documented, particularly if the material may later be used in a legal proceeding.

Because security work is scheduled around site visits, client meetings and field assignments, businesses in this field commonly operate by appointment rather than maintaining walk-in hours. Calling ahead is the most reliable way to confirm availability, discuss a specific concern and determine whether an in-person visit or a phone consultation is the appropriate starting point. Prospective clients may also find it helpful to gather basic information before making contact, such as the address and square footage of the site in question, existing alarm or camera equipment, hours of operation, and a description of any incidents that prompted the inquiry.
