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. Tiana

 Trustindex 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.

 Trustindex 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!

 Trustindex 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.

Sewage backups can expose you to harmful bacteria, viruses, and parasites, leading to illnesses like gastrointestinal infections, respiratory problems, and skin rashes.

Is it safe to stay in the building after a sewage backup occurs?

No, it’s not safe. Sewage water can contaminate your home, and the risks of infection and exposure to toxic substances make it important to leave until professionals handle the cleanup.

What items should I move or protect in the affected area?

Move valuable or sentimental items, electronics, and furniture away from the affected area. Cover carpets and flooring if possible, to minimize damage.

How quickly should sewage backup be addressed?

As soon as possible! Addressing it within the first 24 hours prevents further contamination, mould growth, and more severe damage.

What causes sewage backups, and how can they be prevented?

Sewage backups are often caused by clogged drains, tree root intrusions, or faulty plumbing. Regular maintenance and inspections can help prevent blockage and damage.
