Do you know three commonly overlooked household hazards that are not addressed properly? As parents and homeowners in Greenwich, Stamford, and across Fairfield County, we all take pride in keeping our homes clean and safe. We mop, disinfect, and vacuum—sometimes daily—because protecting our families is priority number one.
But here’s the reality: even the most well-maintained home can hide dangerous hazards that no mom, dad, or property owner should try to tackle without proper training and equipment. From unexpected plumbing issues to hidden mold growth to situations no family ever wants to imagine, these are moments when DIY cleaning just isn’t enough. In fact, trying to handle them yourself can actually make things worse—and put your family’s health at risk.
Here are the three most common biohazards we see in Greenwich, Stamford, and surrounding communities—and why calling certified cleanup professionals is the safest choice.

Overlooked Hazards: Sewage Backups in Toilets or Basements
Few things are more stressful than walking into your bathroom or basement to find water where it doesn’t belong. And sometimes, it’s not just water. Sewage backups are common in coastal towns like Greenwich and Stamford, especially in older neighborhoods with aging infrastructure or after heavy rains overwhelm local systems.
Why It’s Dangerous for Families:
Sewage is filled with harmful bacteria and viruses that can spread illness. It contaminates floors, walls, and even the air inside your home—creating risks for kids, pets, and anyone with a weaker immune system.
What Not to Do:
- Don’t let children or pets near the affected area.
- Don’t try to mop, bleach, or cover it up—household cleaners won’t kill the pathogens.
What to Do Instead:
Call a professional sewage cleanup service in Greenwich or Stamford. Certified technicians at PuroClean wear protective gear, use commercial-grade disinfectants, and restore your property so it’s safe to live in again.
Overlooked Hazards: Musty Smells & Mold Growth in Basements
Basements and crawlspaces in Fairfield County homes are notorious for dampness and humidity—prime conditions for mold. All it takes is a slow leak, stormwater intrusion, or excess moisture, and mold can spread quickly behind walls, on ceilings, or across stored belongings.
Why It’s Dangerous for Families:
Mold exposure can trigger allergies, asthma, and respiratory problems. For kids and seniors, it’s especially harmful.
In New York, mold over 10 square feet legally requires a licensed mold assessment (Article 32, NY Labor Law). Simply painting over mold or scrubbing with vinegar doesn’t solve the issue—it spreads spores and could even put you out of compliance.
What Not to Do:
- Don’t paint or caulk over mold.
- Don’t run fans without containment—you’ll push spores throughout the home.
What to Do Instead:
Search locally for mold remediation in Greenwich or Stamford. PuroClean of Greenwich | Stamford sets up containment, uses HEPA filtration, and follows strict remediation standards so your family can breathe safely again.

Overlooked Hazards: Blood or Bodily Fluid Accidents
Accidents can happen at home or in a small business—sometimes in ways families never expect. From injuries to more traumatic events, blood and bodily fluids create a dangerous biohazard.
Why It’s Dangerous for Families:
Blood can carry pathogens like Hepatitis B, Hepatitis C, and HIV. Once it soaks into carpets, couches, or flooring, it’s nearly impossible to disinfect without professional equipment.
What Not to Do:
- Don’t throw contaminated items in the household trash.
- Don’t rely on store-bought cleaners—they won’t fully sanitize.
What to Do Instead:
Call a certified biohazard cleanup service in Stamford or Greenwich. PuroClean’s trained teams handle the situation discreetly, safely, and in compliance with OSHA and state regulations.
