Windsor Electric

What Windsor Electric does

Windsor Electric Co., Inc. is a privately held, family-owned commercial and industrial electrical contractor founded in 1955 by Donald Kirk, Sr. and headquartered in Owings Mills, Maryland. The company operates as a Mid-Atlantic specialty subcontractor delivering electrical construction services to general contractors (including Whiting-Turner, Clark Construction, DPR, and Harvey Cleary Builders), public and private institutions, and end-clients across healthcare, education, commercial, retail, entertainment, and industrial segments in Maryland, Virginia, Washington D.C., and Southern Pennsylvania.

Its service offering is structured around three divisions: Pre-Construction Services (budgeting, scheduling, constructability analysis), Construction Services (electrical installation for new builds, alterations, expansions, and upgrades covering power, lighting, fire alarm, computer and data wiring), and Service & Maintenance (24/7 emergency response and recurring maintenance using fully equipped bucket and crane/auger trucks). Field supervisors are equipped with tablets and tools such as Bluebeam and Trimble layout to support project execution. Notable recent project work includes the 285,000 sq ft Under Armour TBM2 mass timber headquarters, 200,000 sq ft Suburban Hospital (Johns Hopkins) addition, 173,000 sq ft Anne Arundel Community College Health & Life Sciences building, and a 105,000 sq ft global HQ fit-out with a new data center for Tenable.

Windsor Electric generates revenue through one-time project-based contracts on a quote basis, with no publicly disclosed pricing. Distribution is direct sales-led: an in-house estimating team bids work from GCs and institutions, and a 24/7 service department captures recurring commercial maintenance and emergency response. The company is family-controlled (Donald Kirk Jr. as CEO, Edward Kirk as President), has 11-50 employees, and has accumulated multiple industry recognitions including three consecutive ABC Platinum STEP Safety Awards, an ABC National Pyramid Award (2023), and an ABC Diamond Award (2025). It is an active member of ABC Baltimore, ASA Baltimore, IEC Chesapeake, Building Congress & Exchange, Chesapeake Region Safety Council, and HCECA, and partners with Carroll Community College on an electrical apprenticeship program.
