In addition, they helped us with  the company that we used to buy flooring for the bathroom and carpeting for the remainder of the house.  I am back home and very pleased with everything.

 Trustindex verifies that the original source of the review is Google. An inspection revealed groundwater in our crawlspace.  Another business never got back to me with an estimate so I call 911 Restoration.  They came out the next day and gave me an estimate (Very Reasonable) and scheduled the work to begin in 4 days.  Due to a snowstorm they had to delay two days, but got the work done promptly and professionally.  I would contact them first in the future if I had need of their services.

 Trustindex verifies that the original source of the review is Google. We recently had a water damage in our house and called 911 Restoration. Teya was courteous, explained what needs to be done, and answered all our questions patiently. The water mitigation crew were timely, professional, and efficient. They brought in equipment to dry the floor, removed damaged items, cleaned/sanitized, as well as thoroughly documented the damage for insurance. I would highly recommend them to anyone dealing with such a situation!

Our Sewage Backup Cleanup Process

STEP

1 Emergency Response & Containment

We arrive within 45 minutes to inspect the affected area, identify the cause of the backup, and contain the contamination to prevent it from spreading. Immediate response is essential to minimize damage and health risks.

STEP

2 Safe Cleanup & Sanitization

Our technicians remove sewage and contaminated materials using professional-grade pumps and protective equipment. We then deep clean and disinfect the entire area with EPA-approved solutions, ensuring all bacteria, viruses, and odors are completely eliminated.

STEP

3 Drying & Restoration

After sanitization, we thoroughly dry the space using industrial dehumidifiers to prevent mold growth and structural damage. We then repair or replace affected materials such as drywall, flooring, and insulation — restoring your property to a safe, clean, and livable condition.
