What this listing says

Best for
- Flagstaff-area homeowners who need water damage cleanup and mold remediation handled by the same company that does the rebuild.

- Homeowners dealing with frozen pipe bursts who need someone on-site fast — reviewers confirm rapid response times, sometimes within 30 minutes.
About this company
Mammoth Restoration is a full-service restoration company headquartered in Flagstaff, Arizona. They handle water damage, mold remediation, fire and smoke damage, biohazard and trauma cleanup, and reconstruction — all under one roof. They also run separate pest control and construction divisions.
What stands out is the scope. Most restoration companies subcontract reconstruction. Mammoth keeps it in-house, which means one company handles everything from emergency water extraction through drywall replacement. They offer financing for restoration work and coordinate directly with insurance companies. They hold two Arizona ROC contractor licenses and advertise 24/7 emergency availability.
The company claims 20-plus years of experience in construction and project management. They serve a wide swath of Northern Arizona, with service area pages for Flagstaff, Payson, Kingman, Lake Havasu City, Bullhead City, Fort Mohave, and several smaller communities.
With a 4.8-star rating across 162 Google reviews, Mammoth sits well above average. The volume is notable for a Northern Arizona market — most competitors in Flagstaff have far fewer reviews.
Services
Service area
Headquartered in Flagstaff, Arizona. Serves Northern Arizona including Payson, Kingman, Fort Mohave, Lake Havasu City, Bullhead City, Peach Springs, Golden Valley, Hualapai, Yucca, Hackberry, and Mojave City. That covers a radius of roughly 200 miles from Flagstaff, so response times will vary significantly by location.
Review consensus
Carter and Erin dominate the positive reviews, though both appear to work on the pest control side. Carter gets repeated praise for being on time, detail-oriented, and trustworthy in customers' homes. Erin is described as friendly, knowledgeable, and proactive — one reviewer noted she came back to repair an attic hole she found during an inspection. On the restoration side, Jose gets credit for fast emergency response (within 30 minutes in one case) and staying until the job was done. Peter drew praise for going above and beyond, including helping a customer find a cheaper alternative even though it would cost him the job. Michael is named positively as a plumber. Several reviewers mention fast emergency response as a consistent strength.
4 found across 162 total reviews at 4.8★. Mary Harmych says Mammoth completed mold remediation during her home purchase but has not returned a $500 deposit after a month of emails and calls. Chance Boultinghouse hired them for asbestos abatement and describes a job that left black adhesive residue throughout the house — on baseboards, walls, cabinets, patio, and driveway — with no cleanup. He says crews came back the next day but still did not fully resolve the mess. Alfie's brief review claims nobody in the company — supervisors, contractors, or the owner — knows what is going on, and nothing gets inspected. Vicente Vega left a two-word review with no detail.
The negative reviews cluster around project management rather than technical skill. Communication gaps, slow follow-through, and disorganization appear in the detailed complaints from both Stephanie Quiroz (2-star) and Chance Boultinghouse (1-star). Meanwhile, the owner's responses are nearly all identical boilerplate — the same paragraph copied across every negative review regardless of the complaint. The one exception is the 3-star review, which got a slightly more personalized reply. This template approach suggests reputation management rather than genuine engagement with specific issues.
Carter (pest control technician — consistently positive, praised for punctuality, thoroughness, and friendliness across many reviews). Erin Brugler (pest control technician — consistently positive, praised for knowledge, friendliness, and going the extra mile). Jose (restoration/water damage technician — positive, praised for fast emergency response and diligent work). Zack (Jose's supervisor — positive, mentioned working alongside Jose on emergency cleanup). Peter (restoration — positive, praised for kindness and putting the customer's interest first). Michael (plumber — positive, called courteous and helpful). Emma (staff — positive, thanked by name). Kyla (staff — positive, thanked by name). Connor (roofing crew lead — positive, praised for quality metal roof installation in Kingman). Stacie (staff — positive, praised for courtesy).
Mammoth's strength is emergency response — reviewers consistently confirm fast arrival times and competent water damage work. For longer restoration projects that involve reconstruction, push for a single point of contact and a written timeline upfront. Ask specifically about their experience with your type of work, especially if it falls outside water damage and mold remediation.
Keep in mind
- Multiple reviewers report communication breakdowns on longer restoration projects. One reviewer went three weeks without hearing from anyone, and another saw their contract manager change three times during a four-month job.
- One reviewer's asbestos abatement job went badly — adhesive residue left on walls, baseboards, patio, and driveway with no cleanup attempt. Mammoth handles asbestos removal alongside their other services, but this review suggests it may not be a core strength.
- The owner responds to most negative reviews, but nearly every response uses identical template language. This makes it hard to tell whether complaints are actually being addressed internally.
- Their service area stretches from Flagstaff to Lake Havasu City and Bullhead City — roughly 200 miles. Response times for locations far from Flagstaff may differ from what Flagstaff-area reviewers report.
