Recommended Customer Reviews

I had an extensive flood in my home.
Mammoth did an assessment for mold remediation.
I spoke with the manager of the company to review services line by line. When we got to the 8 th line, the manager rudely said "" I am too busy to go line by line, what do you want done"" I relied I emailed the air quality mold report, and anything with mold was to be removed. He didn't even have time to read the mold report from Silver hammer Inspections. When asked about how to handle a final mold test and if it doesn't pass, abruptly, he replied, ""you have to keep playing until it passes""
This company is unprofessional, with the demeanor too busy for customer service. Is this the kind of company you want to remediate your home?
Move on get another company !

I paid $395 for Mammoth to come and assess water damage. The mobile house in Cornville AZ was new and it was under warranty. I could not read the pictures that they sent me . with their water meters. And they would not help me understand them. They would not bill the warranty people for any repairs they might do and they wanted me to pay first and then try to get the warranty people to pay me back. The invoice they sent me to do the repairs was exorbitant and they hadn't even opened the was to check the extent of the water damage and/or mold. It was a brand new mobile and the dishwasher had not been hooked up right which led to a leak which was immediately fixed when became aware of. They prey on your fear and want you to pay a lot of money quickly to avoid any more damage. I would not recommend them! Mary Lynn Sheldo

I had a nasty water leak that led to mold in my kitchen. It had started in April but we didn't catch it until July, which is when I started having health issues from the mold. We ultimately called another company that never showed so we called mammoth at that point in the beginning of August. It took mammoth about 3-4 weeks total to gut my kitchen and cure the mold. Thankfully since the damage wasn't that bad yet. I mean it was bad, but it was fixable. I had 2 consistent workers that were really great. Friendly, easy to talk to guys. Can't remember their names but I would recommend them to anyone in this same situation. The day the wood floors (that I was heartbroken to loose) had to come out, they had about 4 other people to help with tear out and clean up. Those folks were nice too. I did have some hiccups with the machine that had to be hooked up to my furnace. While I was upset it was casing my AC system to fail, they had their HVAC person check everything out and eased my mind saying it was ok. So I feel they were amazing at listening to any concerns I had. I believe my point of contact was Michelle Heater. I absolutely adore her. She was the person I could email and call and she was on my team helping me get this stuff figured out. This was an insurance job (Best Buy's insurance) so we struggled to get them to pay after they documented they'd pay in email. I never felt harassed by mammoth. We worked together to get that check cut and got it paid. One thing that did occur was the flooring in the kitchen was cut too deep from the saw blade not being set which cost us a good chunk of extra change we paid out of pocket. When we had engineer come out and inspect all the work and damage, he advised this was caused by mammoth. So we worked it out with them and had that amount taken off the total bill. I was very grateful for them working with me on that. But of I didn't have an engineer report stating such, we may not have recouped that money. We ultimately had our flooring done elsewhere because believe it or not, this was finished by mammoth in August but they barely called in December to finish construction. So I advised we already finished the remodeling but would gladly use them in the future for planned projects. I know we all have different experiences, but even with some setbacks I feel this was a good experience and they got the job done fast considering the mold. The cost was over 18k which I'd assume is reasonable in today's world, but thankfully BB insurance paid for what their installer caused. So I would absolutely recommend mammoth restoration. Just know they are so booked because they are very popular. Always keep your cool and be respectful even when things aren't working out. You'll get more bees with honey, than vinegar! That's what my grandma taught me and it's legit!

Took a job here invested what little money i had to move to flag needed some help getting a place cuase owner said i cant start work without. A place the owner ended up making me homeless dont apply here seriously they company wants u to invest in it but will not invest in its employees

Mammoth USED TO BE a good company. Unfortunately, it is not the case anymore. They send a guy for mold remediation who had no education in mold - we knew more than he did - and could not go under the house to detect leaks as ... he was too fat to fit in. They never sent anybody else. They are a joke. We have had mold remediation 4 times in the past in other states and have undergo some serious process with competent professionals. We tried 2 companies here in AZ and none was even close. No professionalism.

I have had such a difficult time getting people to show up in Munds. I was able to get service the same day, very happy. I was given an estimate prior to arrival and the estimate was good, the work is done and I am impressed. Thank you Mammoth for such a great experience.

If you're an honest man looking for a job, STAY AWAY FROM THIS PLACE. You will either have NO work so you get sent home before lunch time. OR so much work that you don't get home till 10pm. These guys are so delusional they think we LIVE to WORK. And work they will, they will work you like you're not even a human. The work is so nasty, YOU will have to do it while the bosses stay CLEAN and out of harms way. You are the grunt and nothing more. The favoritism is crazy here so don't come expecting to go up in the ladder unless you're friends with the owner. I'm here for a check and that's all but this job is horrible. The bosses are the bosses and the grunts are the grunts but spend your energy somewhere else who appreciates the work you put in, you will not get that here

I had a flood in my rental due to a leaky roof and I called Mammoth. Within an hour they came out, on a weekend nonetheless. They quickly got it patched up and then came back out to rebuild my kitchen, the next day, after all the damage was taken care of. My short-term renters were coming to the property that week and everything was repaired before they got there. Super happy with these guys! I can't thank them enough.

If you notice, the reviews older than 2022 are all 5-star. Something has happened in the last two years that has really messed up this company. Our new home had major water damage, and Mammoth quickly cleared out everything from flooring, drywall, to furniture. Once everything was dried out, we were told it would be 3-4 months before they could fix things, and they wouldn't even give us a complete estimate.
We went with JB Restoration because they were honest, immediately got to work, and did an awesome job.

We have had a great experience with mammoth- responsive, good work, fair prices. Would definitely use again!
