Every hour counts during a sewage emergency. Raw sewage contains dangerous bacteria, viruses, and pathogens that spread rapidly through your property. Waiting even a few hours to begin emergency sewage cleanup allows contamination to penetrate deeper into floors, walls, and belongings — dramatically increasing health risks and repair costs.
Immediate emergency sewage backup cleanup removes contamination fast, stops the spread of bacteria, and helps prevent long-term damage to your property and health.

Nijen's team replaced and build a privacy wall on our back deck last Friday. They were professional, and efficient and we couldn't be happier with the end result. Thank you to Nijen and his team. We would definitely hire them again for our renovation needs and recommend them to everyone. TianaPosted on Mathew WhiteTrustindex verifies that the original source of the review is Google. 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 siddharth khannaTrustindex verifies that the original source of the review is Google. I called them at 7 am for an emergency basement pipe burst leakage and they sent out a crew within a couple of hours who knew exactly what needed to be done. They documented the damage thoroughly for insurance purposes and I faced no trouble. The team at GTA are professional and helpful. Totally recommend!Posted on Mark EsdaleTrustindex verifies that the original source of the review is 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.
