A contractor from Mammoth came out to look at some water damage we had. He was very generous in walking me through how I might fix the damage myself, including sending me links to all the products I would need. He was respectful and informative.

Very easy to communicate with.
He did a fantastic job and he was very courteous, he made sure he cleaned up his mess completely and that I was ok with the work
Mammoth Construction did a great job on the remodeling they did in my home. The work they did is very satisfactory to me. They fulfilled my requests. They made sure I was pleased with the upgrades before the work for them was considered complete.

Absolutely terrible and rude. Avoid unless you're an engineer capable of construction project management, and ready to babysit David and his crew every day. Those folks should have their license revoked. They know nothing about joist span tables. They don't know which fasteners to use and will try to use lowest gauge and shortest nails. They don't know that there are different types of screws for fastening different materials. They don't know how to frame properly - some wall framing will be attached to roof's OSB rather than to rafters. Shingles will be nailed anywhere up to 5 inches above and below the nailing line. Hired them to build a new roof, ended up with water damage of the main level ceilings, and some holes in the ceiling as someone stepped on it from above. Instead of apologies I received an offer to roughly fix it with plaster and patch paint, without full repaint of the ceiling. They had to redo shingles and hired subs for pretty much anything besides framing. Mammoth doesn't hire pros but relies on friends and family to do the project. So don't be surprised if wife of David's brother will be working on your project. David will disappear once the project is half-done and will switch to another job. He will also stop responding phone calls and will tell you that your calls don't get through. I guess they can probably build you a flower bed or a fence, maybe pour concrete. Never hire them for anything more complex than that.
