Standing water in your Onalaska property is a race you're losing every minute. Our truck-mounted water removal systems extract thousands of gallons per hour — and our Onalaska crew can be at your door in under 60 minutes, any hour, any day.
The right water removal team in Onalaska gets to you fast, removes the water completely, and transitions immediately to structural protection — not a service that extracts visible water and leaves hidden moisture to fuel mold growth.
Local crews and pre-staged equipment mean our Onalaska Emergency Water Removal team arrives faster than regional contractors every time. We target 60 minutes from your call to boots on the floor.
Clean supply line failures, Category 2 gray water overflows, and Category 3 sewage-contaminated events each require different extraction methods and PPE. Our Onalaska team is trained and equipped for every classification.
No surprise billing after the fact — your written estimate is your price, period.
From the moment we arrive, our Onalaska crew builds the documentation your carrier needs: pre-extraction photos, water category determination, volume estimates, and equipment deployment records. A complete file from the start means a faster claim.
COS Water Damage Restoration's Emergency Water Removal in Onalaska covers the full spectrum of water intrusion events — from minor appliance overflows to major storm flooding, and every source of water damage in between.
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.
After extraction, crawlspace vapor barrier inspection and replacement prevents recurring moisture accumulation.
Category 3 water — sewage overflows, sump pit backup, and groundwater intrusion — requires full PPE protocols, contained extraction, and regulated disposal procedures. Our Onalaska 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 Onalaska crew extracts surface water and immediately transitions to moisture detection to catch sub-surface migration before drying equipment placement.
We produce the detailed commercial loss documentation that commercial insurance adjusters require.


Every call connects to a real person who starts your Onalaska response before you hang up.
Our Onalaska Emergency Water Removal crew loads the extraction equipment specific to your scenario during transit so they're productive within minutes of arrival. Our target is on-site in 60 minutes or less, with your dispatcher providing real-time updates if conditions change en route.
No equipment gets placed without your written approval of the scope and cost.
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 Onalaska 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 Onalaska 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 Onalaska 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."
