All the guys that worked on our restoration were very polite and respectful to make sure everything was cleaned up each day. Oscar worked the last week finishing up on the drywall and painting. He did a very good job and was so polite.
Wo would definitely recommend First Onsite. Thank you all for the great job.

As a business owner with a commercial building for 18 years, this is the third water leak I have dealt with. This is the best experience by far. Great communication, deadlines met. Hope I never need a restoration company again but if I do this is without a doubt the company that I would use.

First Onsite: A Nightmare Experience
Our dealings with First Onsite were an absolute nightmare from start to finish. After a devastating house fire left us in need of a complete rebuild, we turned to them for help, but it turned out to be a colossal mistake.
Horrible Communicators: Communication with this company was virtually non-existent. They ignored our calls and messages for weeks on end, leaving us in the dark about the progress of our project. It felt like we were constantly chasing after them for updates.
Endless Delays and Excuses: Months passed without any significant work being completed. When they did bother to respond, it was always with a litany of excuses. They seemed more interested in avoiding accountability than in getting the job done. We ended up having to end our relationship with them mid-project which set ups back months in getting back into our home.
Unjust Charges: To add insult to injury, First Onsite attempted to charge us for work that was never even performed. Their billing practices were dishonest and exploitative, taking advantage of our vulnerability in a time of crisis.
Demanding More Money for Incomplete Work: Incredibly, at the end of this nightmare, they had the audacity to demand even more money for a job that they had hardly even started. They sent us multiple lien notices with incorrect work completion dates attached to them.
Our experience with First Onsite was nothing short of a disaster, and we would strongly caution anyone against ever engaging their services. They proved themselves to be unprofessional, unreliable, and dishonest throughout our ordeal.
Even 1 star is too many.
