What to Do After a Sewage Backup in Your Home

After a sewage backup in your home, keep people out of the affected area, shut off power to that room only if you can do it safely, and call a 24/7 professional sewage cleanup team right away. The key danger is contaminated “black water” with harmful microbes that needs industry-standard disinfection, not household cleaners. Colorado Cleanup Services provides 24/7 emergency sewage cleanup with IICRC-certified technicians using hospital-grade disinfectants. Our crew handles sewage cleanups across the Denver metro and can work directly with your insurance. Technician insight: if sewage touches drywall or baseboards, expect moisture to wick higher than the visible stain.

While you wait, take only these steps:

• Stop using sinks, showers, and toilets to limit new backups.
• Keep children, seniors, and pets away; avoid skin contact.
• Do not vacuum or mop sewage; leave it to pros with protective gear.
• Ventilate with open windows if conditions allow. The safest move is to avoid running any water until a licensed plumber or restoration professional confirms the line is clear. <br/>
