First Onsite

First Onsite is a large-scale construction, property restoration, and emergency response company that serves commercial, industrial, and government clients across North America. Operating from more than 110 locations with over 2,600 team members, the company positions itself as a single partner for both planned infrastructure work and unplanned disruption — building, sustaining, and restoring mission-critical facilities where delays and downtime are not acceptable. Its service range spans large and complex construction, emergency response and stabilization, property restoration, operations and maintenance, program management, and environmental services. The company's emergency and restoration capabilities include water damage restoration, fire and smoke damage restoration, flood and hurricane damage response, wildfire and winter weather response, mold remediation, asbestos abatement, infection control and disinfection, moisture mapping, water extraction, dehumidification, odor removal, board up, temporary power, climate control, and contents restoration. On the construction side, First Onsite offers general contracting, reconstruction, construction management, and complex claims support. This dual capability — planned construction plus 24/7 emergency response — is central to its brand promise: "First to answer. First to arrive." First Onsite is a subsidiary of FirstService Corporation (NASDAQ: FSV), a publicly traded services company. That parent relationship gives First Onsite what it describes as the financial strength to back large, complex programs without interruption. The company markets itself under the tagline "The only partner you'll ever need," emphasizing local teams backed by national resources and pre-staged equipment that can be mobilized quickly at any scale. Its client base is primarily commercial, industrial, and government organizations — property owners and operators for whom facility downtime carries significant cost. First Onsite's published client stories include complex recovery projects such as the restoration and reconstruction of a heritage bank building in Fort Worth, Texas, that had been converted into a hotel and was damaged by a gas explosion. The company also provides tailored emergency preparedness planning to help clients minimize downtime and damage before disasters occur.

First Onsite operates as a large-scale construction, property restoration, and emergency response company serving commercial, industrial, and government clients globally. According to its own corporate materials, it maintains more than 110 locations and over 2,600 team members across North America, with pre-staged equipment positioned to mobilize quickly for emergencies. The company is a subsidiary of FirstService Corporation (NASDAQ: FSV), a publicly traded services company. This parent relationship is highlighted in First Onsite's marketing as providing the financial strength to back large, complex programs without interruption. FirstService Corporation is a North American leader in property services, and First Onsite represents its large-scale restoration and construction platform. First Onsite's business model combines two sides of what it calls the disruption cycle. On the planned side, it delivers large and complex construction, general contracting, reconstruction, construction management, program management, operations and maintenance, and environmental services. On the unplanned side, it provides 24/7 emergency response and stabilization, water damage restoration, fire and smoke damage restoration, flood and hurricane response, wildfire and winter weather response, mold remediation, asbestos abatement, infection control and disinfection, and related recovery services. The company's published client stories illustrate the scale and complexity of its work. One notable project involved the restoration and reconstruction of a heritage building in Fort Worth, Texas — originally a bank building begun in 1919 and completed in 1921, later retrofitted into a 22-story hotel with a restaurant space in the lower basement. A gas explosion on the lowest basement level collapsed the first floor into the basement. First Onsite responded to the incident and carried out a complex recovery and reconstruction effort that preserved unique architectural features such as Italian and Turkish marble and art deco detailing. First Onsite markets itself under the tagline "The only partner you'll ever need," emphasizing a combination of local teams with regional presence and national resources. Its stated values include a sense of urgency, gathering and growing talent, accountability, doing the right thing, and having fun. The company positions its emergency preparedness planning services as a way to help clients minimize downtime and damage through tailored response plans and clear protocols.
