About this company
FIRST ONSITE Property Restoration runs a Jacksonville office out of Suite 507 on Florida Mining Blvd, focused on commercial and multi-family residential restoration. The Jacksonville location is relatively new and positions itself as a go-to for property managers across Northeast Florida. The parent company operates 110+ locations across the U.S. and Canada and is owned by FirstService Corporation.
The Jacksonville team handles water damage, fire and smoke restoration, mold remediation, storm damage, and large-scale loss recovery. They offer a pre-loss planning program where they familiarize themselves with your property before anything goes wrong, which can speed up response when an emergency hits. Their field technicians carry IICRC water restoration technician training, and the mold page describes containment with negative air pressure and disinfectant application. They also do contents restoration, including pack-out, cleaning, and climate-controlled storage.
FIRST ONSITE started as Interstate Restoration in San Antonio in 1998 and grew through acquisitions. In 2019, FirstService Corporation bought the company, and it rebranded as FIRST ONSITE. The Jacksonville office opened around 2024 and has built its client base primarily among multi-family and commercial office facility managers.

The Jacksonville office has cycled through different lead technicians over its short history. Oscar Mejias dominated reviews in mid-to-late 2024, while Sean has become the prominent name in 2026 reviews. This suggests either role changes or territory reassignment within the team. The review base leans heavily toward property managers and apartment complex operators rather than individual homeowners, which aligns with the company's stated commercial and multi-family focus.

With 27 reviews and a 5.0-star rating, this Jacksonville office has a spotless track record so far. Ask for Sean or Oscar depending on your project type, and confirm that the specific team members reviewers praise are still at this location. The small review count and short operating history mean the track record is promising but not yet deeply tested.
Keep in mind
- FIRST ONSITE does both mold testing and mold remediation. When the same company tests and remediates, they have a financial incentive to find problems. Consider hiring an independent assessor for the initial mold evaluation.
- This is a national chain, not a locally owned operation. Your experience depends on the Jacksonville team, not the national brand. Staff turnover at this location could change the service quality reviewers describe.
- The service area claims stretch from Jacksonville to Gainesville, Lake City, and the Panhandle. That covers a wide geographic range. Confirm actual response times for locations outside the Jacksonville metro.
- The Jacksonville office has been open for roughly one to two years. The 27-review sample is small compared to longer-established local competitors.
