Commercial Sewage & Drain Backup Cleanup

Protect Your Business from Hazardous Sewage Damage.

When a sewage or drain backup hits your commercial property, immediate action isn’t optional — it’s mandatory. Contaminated water destroys flooring, walls, inventory, and creates serious health and safety risks for employees and customers.

PDX Restoration specializes in commercial sewage and drain backup cleanup. Our team restores your property to a safe, fully operational condition fast. We know downtime costs money, so we respond 24/7 with advanced extraction, sanitation, and drying systems capable of handling any level of contamination — from restroom overflows to full sewer line failures.

Why Sewage Backups Demand Immediate Professional Response

Sewage backups aren’t standard water damage — the water is classified as a biohazard (“black water”). It contains harmful bacteria, viruses, and pathogens that require certified remediation. Improper handling leads to long-term damage, mold growth, and regulatory violations.

Common causes of sewage & drain backups in commercial buildings:

PDX Restoration’s certified technicians don’t just remove contaminated water — we fully decontaminate, disinfect, deodorize, and restore your business to pre-loss condition using industry-leading safety protocols.

Our Commercial Sewage & Drain Backup Cleanup Process

We follow a detailed, step-by-step process to ensure your property is safe, compliant, and restored efficiently:

Emergency Response & Assessment

Our 24/7 emergency response team arrives promptly to assess the extent of the contamination. We identify affected zones, classify water damage levels, and determine the safest, most effective restoration plan.

Containment & Safety Measures

To prevent cross-contamination, we isolate the affected areas using professional-grade containment barriers and negative air systems. Our technicians wear full protective gear (PPE) and follow OSHA and IICRC safety standards.

Sewage Extraction & Disposal

We use high-powered extraction equipment to remove standing sewage and contaminated water safely. Waste is transported and disposed of following environmental and local regulatory guidelines.

Cleaning & Disinfection

All affected surfaces — including floors, walls, furniture, and equipment — are thoroughly cleaned using EPA-approved disinfectants. We pay special attention to high-contact and porous materials to eliminate pathogens and odors.

Structural Drying & Dehumidification

Once the contamination is removed, our industrial-grade air movers and dehumidifiers restore normal humidity levels, preventing mold and structural damage.

Odor Removal

Lingering sewage odors are eliminated through advanced deodorization methods such as hydroxyl treatment and ozone generators, ensuring your business smells fresh and clean again.

Restoration & Rebuild

If the damage requires replacement or reconstruction, our in-house restoration team repairs drywall, flooring, or structural components, bringing your property back to pre-loss or better condition.
