First Onsite, in Honolulu, did a great job responding to and repairing water damage caused by the condo above mine.
Excellent customer service from Dee and Chris. Would highly recommend.

Session on ICRA 2.0 was very well done. Speaker was excellent, demonstrations were insightful, and group work highly effective. The food was far beyond expectations. Thank you Spark for food and Shriners for outstanding venue!

The real test of a company’s integrity is when they get things wrong and won’t have the payday they expect. How do they then treat the job and their customer?
First Onsite failed that test spectacularly.
They tore a big piece out of our wall, did tests that determined there actually was no mold or water damage issues after all, and then promptly disappeared.
Over a month later, we still have a hole in our bathroom wall, all our toiletries in a wagon and everything formerly on the wall still cluttering up our bedroom.
First Onsite has not only disappeared, they've refused to give us a copy of the test results saying there is no damage or to even give us an estimate to fix the wall.
It’s been over a month of ghosting us, not returning calls, repeatedly not giving us anything we’ve asked for and never giving us a straight answer once we do manage to get someone on the phone.
Read some of the highlights of an email I finally sent after both my wife and I got fed up.
Then decide if this is who you want for your next job.
EMAIL HIGHLIGHTS:
Dealing with First Onsite has been easily one of the most unprofessional experiences we’ve ever had.
You are also the most unresponsive company we’ve dealt with as well.
- JUNE 8th
Carlton has told me a few days before that the team will be coming in, but presented this to me as a visit for them to figure out what they would do and where. That’s it.
The men show up and tell me, No, we’re tearing out the wall today. News to me.
- A few days later the testing team comes in and gives me good news. There’s no mold issues or water damage. All that’s needed now is to put drywall back up.
I tell them that I would like a copy of the test results saying that it’s all good.
I’m assuming, wrongly, that I will be hearing from First Onsite soon about doing restoring the wall and getting us the test results.
That was a month ago and neither has happened and both my wife & I have experienced nothing but evasion and outright ghosting.
- I left Carlton a VM asking him for an estimate and a copy of the test results at least 3 weeks ago, after not getting anything I requested the week before. He never called me back.
I had to follow up with Carlton again after a week of waiting for him to get back to me.
When I did get Carlton on the phone, he wouldn’t give me a straight answer on the results or the estimate and said he would get back to me. That never happened.
- WEEK OF JUNE 30th
Carlton went on vacation, leaving no instructions to his team about our bathroom.
My wife made repeated calls to him, only finding out by accident that he was ‘out of the country’.
She couldn’t get response from the First Onsite office so she finally called the Mainland corporate number and was given several names to try.
She then was told to text to Bryan photos and measurements of the wall opening.
An estimate was promised to be delivered to her Friday. Nothing ever came.
- WEEK OF JULY 6th
Finally, I got an email from ’Scott’ on Monday, July 6th saying he could do the drywall possibly on Tuesday.
I called Scott and told him, again, no work until I got the estimate and the test results and that I wanted both today.
Scott said he would tell Carlton.
Carlton finally sent an email around 2PM, but not because of my request.
He replied to our building manager who contacted him. He never acknowledged anything in his email that I told Scott, just saying he was ‘working on the estimate’. After a month has gone by. And not a word about the test results.
When someone refuses to give you an estimate on some drywall work or let you have a copy of test results, that raises a lot of red flags.
- Your initial $12,000+ estimate raised our insurance by $100/Month, despite the fact that there is nothing to clean up.
Even with that cost of living raise you created, we’ve had to notify our insurance company that we’re returning the check due to the initial tests being wrong.
So all we’ve gotten out of dealing with First Onsite was a bigger bill every month from now on.
