Standing water in your Severn property is a race you're losing every minute. Our truck-mounted water removal systems extract thousands of gallons per hour — and our Severn crew can be at your door in under 60 minutes, any hour, any day.
Speed and completeness are what separate a manageable water event from a months-long rebuilding project. Here's how COS Water Damage Restoration delivers both in Severn.
Your water removal response time is directly determined by where the crew is based. Ours is based in Severn.
Clean supply line failures, Category 2 gray water overflows, and Category 3 sewage-contaminated events each require different extraction methods and PPE. Our Severn team is trained and equipped for every classification.
No surprise billing after the fact — your written estimate is your price, period.
We document everything at the extraction phase — before conditions change and evidence is lost.
Every Emergency Water Removal scenario requires the right equipment, the right technique, and the right team. Here's what we handle in Severn.
Rapid volume removal at this stage prevents saturation from reaching framing and subfloor materials.
Fast extraction at the point of failure combined with cavity access drying limits the drywall and framing removal scope.
Basement and crawlspace flooding in Severn requires submersible and portable extraction systems capable of working in low-clearance and confined environments. Our crews carry the right equipment for each scenario — including high-capacity submersible pumps for deep standing water and portable extractors for post-pump residual water in below-grade spaces.
Category 3 water — sewage overflows, sump pit backup, and groundwater intrusion — requires full PPE protocols, contained extraction, and regulated disposal procedures. Our Severn Emergency Water Removal team handles contaminated water events with the proper containment barriers, biohazard-rated extraction equipment, and antimicrobial pre-treatment before structural drying begins.
Our Severn crew extracts surface water and immediately transitions to moisture detection to catch sub-surface migration before drying equipment placement.
Water events in Severn commercial properties carry additional complexity: larger square footages, infrastructure like server rooms and electrical panels, business interruption risk, and tenant notification requirements. Our commercial Emergency Water Removal team in Severn deploys at scale — multiple extraction units, larger crew sizes, after-hours scheduling to minimize disruption — and maintains a dedicated project manager for commercial loss communication.


Every call connects to a real person who starts your Severn response before you hang up.
Local crew, local knowledge, and fast roads — your Severn response is as fast as it can be.
On arrival, our crew assesses the water source, category, and extent of migration before placing any equipment. A written scope and cost estimate is prepared and reviewed with you before extraction begins — the number you approve is the invoice you receive.
Extraction continues until standing water is completely eliminated and surface moisture is at levels appropriate for structural drying handoff. Our crew immediately stages dehumidifiers and air movers to begin the drying phase — preventing the 24-48 hour mold risk window from opening.



"A pipe burst in our Severn home's basement at 11 p.m. on a Saturday. I was bracing for a long night of being on hold. COS Water Damage Restoration answered on the second ring, had a crew at my door in 52 minutes, and the standing water was completely out before 2 a.m. They stayed to set up the drying equipment and I woke up to a dehumidifier running and a dry basement floor. Absolutely excellent."
"My Severn rental had a Category 3 sewage backup and I honestly didn't know who to call. COS Water Damage Restoration handled the entire thing — proper containment, professional extraction with the right equipment for contaminated water, and antimicrobial treatment before they left. My tenants were back in within the timeline they promised. Transparent, professional, and they charged exactly what they quoted."
"Three different companies told me they could help with our Severn storm flooding. Only COS Water Damage Restoration showed up with a truck-mounted extraction unit instead of a few shop vacs. The difference in output was enormous — they pulled the water out in a fraction of the time I expected. Highly recommend calling them first."
