A sewer backup hit our basement floor drain during a big storm. The crew handled the cleanup carefully and explained why certain materials had to be removed instead of just cleaned. They also caught mold starting near the baseboard before it spread further.

Our team is based in Auburndale, about 5 minutes from our Auburndale base, so we can usually reach a Waltham home the same day. Our methods follow public guidance from the EPA and the CDC on handling indoor mold safely.

Good to know
Sewage Mold Remediation in Waltham, MA: common questions
Is a sewage backup more dangerous than a regular water leak?
Yes, sewage contamination carries health hazards a clean water leak doesn't, which is why porous materials are typically removed rather than dried and reused.
Does sewage cause mold faster than clean water?
The combination of moisture and organic contamination can create favorable conditions for mold to develop quickly, so fast response matters.
Will insurance cover a sewage backup?
Coverage depends on your specific policy, sometimes requiring a sewer backup rider. We document the damage thoroughly to support your claim.
Do I need to leave my Waltham home during the work?
Usually no. We seal the work area under negative air, so most of the Waltham home stays livable. For larger jobs we will tell you if it is better to step out for a day.
Should I try to clean up a sewage backup myself?
It's best to avoid direct contact and call a professional crew, since proper protective equipment and disposal practices are important for safety.
What materials do you remove after a sewage backup?
Porous materials like carpet, carpet padding, and drywall that contacted sewage are generally removed and disposed of rather than cleaned in place.
