I engaged First On Site as a preferred vendor through my insurance provider following an unsatisfactory experience with another restoration company. Understandably, I approached the process with some hesitation. From the outset, the team at First On Site demonstrated exceptional professionalism. They maintained clear and consistent communication, keeping me informed of all timelines and progress updates. Their responsiveness and attention to detail far exceeded my expectations. Upon arrival, the crew began work immediately and remained focused and diligent throughout the day. Their efficiency, professionalism, and respect for my property were commendable. Additionally, the team effectively liaised with my insurance company, ensuring the scope of work was completed exactly as described and to a high standard. I would not hesitate to recommend First On Site to anyone requiring disaster management or restoration services. Their commitment to quality and client satisfaction is truly exemplary.Posted on Google![]()

After a ice storm related basement flood the GTA team showed us what service meant!. They were here very quickly, with the proper drying equipment and some great staff members. They removed old carpeting/under padding and the bottom 12 inches of drywall from the affected flood area, installed and left drying machines, were back in a week to repair the drywall. We could not have asked for a better job, very glad we chose them.
