A raw sewage backup in a basement is one of the worst things that can happen to a homeowner. Here in Everett, WA, wet Pacific Northwest winters and aging infrastructure mean that Redwood Coast Restoration Inc receives many calls when drains start backing up with blackwater. Redwood Coast Restoration Inc receives the same questions every time an emergency happens. The most common questions asked when disaster strikes plumbing in Everett, WA are answered below.
Why did raw sewage back up into my Everett home?
Most of the time, a Water Damage Restoration Service backup happens because something is blocking your main sewer line. It could be old clay pipes cracking under shifting soil, massive Douglas fir roots invading the joints, or just years of grease and wipes buildup. During heavy downpours, municipal lines can also get overwhelmed, pushing water backward into residential lateral lines. If you live in an older neighborhood near downtown Everett or up toward Bayside, those older clay and cast-iron sewer systems are especially prone to trouble when heavy rains hit.
Can I just clean up the mess myself with bleach and a mop?
You should not clean up sewage yourself. Raw sewage is classified as blackwater because it is loaded with harmful bacteria, viruses, and parasites like E. coli and hepatitis. Scrubbing it without proper personal protective equipment, commercial-grade negative air machines, and Environmental Protection Agency-registered hospital disinfectants puts your health at serious risk. Porous materials like drywall, carpet padding, and insulation that absorb sewage usually cannot be saved anyway; they have to be bagged out and hauled away to a licensed facility. Trying a do-it-yourself approach often leaves hidden moisture and pathogens behind, leading to toxic mold outbreaks later.
Will my homeowners insurance cover sewage cleanup costs?
That depends entirely on your specific policy, and the answer usually comes down to a technicality. Standard homeowners insurance policies generally exclude ground-level water or sewer backups unless you have specifically added a water backup and sump overflow endorsement. If a tree root crushed your main line outside, or the city line backed up, your insurance carrier will look closely at the cause. Always take plenty of photos before any work starts so you have proof for your adjuster.
How fast do you need to start the cleanup process?
Water Damage Restoration Service work must start right away. Within hours, moisture wicks up drywall and subflooring, warping wood and giving mold spores a head start. Sewage is corrosive, meaning it will start staining and breaking down the structural integrity of your floors remarkably fast. The moment you spot dark water coming up through your basement floor drains or toilets, shut off your main water supply if needed and call for professional help immediately.
What does the actual restoration process look like?
Our first step is to extract all standing liquid and solid waste using heavy-duty pumps. Next, we remove contaminated non-salvageable materials like ruined drywall cuts and soaked carpeting. Then comes the deep cleaning and sanitization phase, where antimicrobial agents are applied to every affected surface. Finally, commercial dehumidifiers and air movers run continuously for 3 to 5 days until moisture meters prove the framing and subfloors are completely dry.
How can I keep this from happening again next winter?
Prevention beats a messy cleanup every single time. Get a camera inspection done on your sewer line, especially if you have mature trees in your yard. If you live in a low-lying area or a spot prone to municipal surcharging during big storms, having a professional plumber install a backwater prevention valve on your main line is a good move.
