Sewage Cleanup in Central Maryland

24/7 emergency response, certified technicians, and clear insurance documentation support — from first call to final restoration.

A sewage backup is one of the most hazardous problems a property can face. Raw sewage is classified as Category 3 "black water" under IICRC S500 standards, meaning it carries bacteria, viruses, parasites, and other pathogens that pose a serious health risk to anyone in the home. Whether the source is a backed-up floor drain, a failed sump pump, an overloaded municipal main, or a broken sewer line, contaminated water spreads quickly into flooring, drywall, and subfloor, and the longer it sits the deeper the contamination travels. Sewage cleanup is never a job for a mop and a bucket; it requires proper containment, personal protective equipment, professional extraction, and full antimicrobial decontamination.

Clean Sweep Enterprises has handled sewage and biohazard losses across Central Maryland since 1991. As a woman-owned, IICRC-certified restoration firm, we treat every sewage call as an emergency and dispatch crews 24/7, because contamination and odor worsen by the hour. Our technicians arrive in full PPE, contain the affected area to stop cross-contamination, extract the waste, remove unsalvageable porous materials, and then clean, sanitize, and deodorize every surface that remains. We document the work with photos and moisture readings so the structure is verified clean and dry — and ready for your chosen rebuild contractor before any rebuilding begins.

We also coordinate directly with your insurance carrier. Many homeowners insurance policies cover sudden sewage backups, especially when a backup-of-sewer-or-drain endorsement is in place, and we provide the detailed scope, photos, and moisture documentation adjusters need to process a claim. From the first phone call through final clearance, our goal is to make a stressful, unsanitary situation as safe and straightforward as possible for your household.

Frequently Asked Questions

Keep everyone, especially children and pets, away from the contaminated area, and do not walk through it or try to clean it yourself. If it's safe to do so, stop using water and avoid flushing toilets or running anything that drains to the affected line. Turn off the HVAC system so it doesn't spread contaminated air and odor, and call us right away. The faster we contain and extract, the less the contamination spreads.
It often is, but coverage depends on your policy. Many carriers cover sudden sewage backups when you carry a "water/sewer backup" endorsement, and some standard policies cover it when the cause is a sudden, accidental event. Gradual seepage or long-neglected maintenance is typically excluded. We document the source, scope, and moisture conditions and coordinate directly with your adjuster so you have what you need to file the claim.
Raw sewage is Category 3 "black water," which carries pathogens that soak into porous materials. Industry standards (IICRC S500) require that contaminated porous materials like carpet, pad, and saturated drywall be removed and disposed of rather than dried in place, because cleaning alone can't reliably make them safe. Hard, non-porous surfaces can usually be cleaned, disinfected, and saved.
Extraction, removal of contaminated materials, and disinfection are usually completed within the first one to two days. Structural drying then typically runs three to five days depending on how saturated the framing and subfloor are, with daily moisture monitoring. We don't consider the job done until readings confirm the structure is dry and clean — leaving the space documented and ready for your rebuild contractor if any rebuilding is needed.
It depends on how much of the home is affected and where. If the backup is contained to a basement or a single room that we can seal off, many families can stay in unaffected areas of the house. If contamination is widespread or the affected area is near living or sleeping spaces, we may recommend staying elsewhere until decontamination is complete. We'll give you a clear, honest recommendation when we assess the loss.
Odor comes from contaminated materials and bacteria, so the first step is removing the source: extracting the waste, taking out unsalvageable porous materials, and disinfecting every contacted surface. From there we use HEPA air scrubbers and professional deodorization to neutralize lingering odor at the molecular level rather than just masking it. Proper drying is also key, since leftover moisture is what allows odor and microbial growth to return.
