Not all water extraction is the same. Consumer-grade shop vacuums pull surface water while saturation continues working into subfloor and wall assemblies. COS Water Damage Restoration's Grand Marsh Water Extraction service deploys truck-mounted commercial systems rated for high-volume output — combined with thermal imaging and moisture metering that maps where the water you can't see has traveled.
Removes water faster than any portable unit.
Maps hidden saturation before drying begins.
Daily readings tracked until drying targets are met.

The gap between a good extraction and a mediocre one isn't visible until weeks later — when mold shows up behind a wall that felt dry after a shop-vac cleanup. Here's what makes COS Water Damage Restoration's Grand Marsh extraction service different.
Every Grand Marsh job gets truck-mounted extraction rated for high-volume output, thermal imaging cameras that reveal sub-surface saturation, and moisture meters that document conditions at every sensor point. Consumer rental equipment doesn't come close.
The faster extraction begins, the smaller the final damage scope. Speed is built into our Grand Marsh operation.
WRT certification isn't a formality — it determines whether your drying plan is based on psychrometric science or guesswork. Every Grand Marsh technician we deploy carries active WRT certification and applies calibrated, documented methods.
On arrival in Grand Marsh, our crew assesses, prepares a written Xactimate-based estimate, and reviews it with you before a single piece of equipment is operated. The approved number is the invoiced number.
COS Water Damage Restoration's Grand Marsh Water Extraction team handles every water extraction scenario — from residential flooding to large commercial events — with equipment and technique matched to the specific situation.
For large-scale events in Grand Marsh, the right equipment makes the difference between hours and days of extraction time.
Extraction of visible standing water is only half the job. Thermal imaging cameras and calibrated moisture meters map where water has traveled beneath flooring, inside wall cavities, and above ceiling assemblies before extraction ends — so the drying plan addresses the complete scope of moisture, not just what was visible on arrival.
Hardwood floor salvage is a specialty — not every water extraction crew in Grand Marsh has the training or equipment to do it right.
Crawlspace water left in place creates lasting structural moisture problems and serves as a primary mold incubation environment.
Carpet may be salvageable when extracted quickly; pad is typically replaced regardless. Our Grand Marsh team makes this determination honestly, based on the data.
Commercial and multi-family properties in Grand Marsh present extraction challenges that residential scenarios don't: larger square footage, multiple affected units, infrastructure protection requirements, and business interruption cost. Our Grand Marsh commercial extraction team scales crew and equipment to match the loss — deploying multiple extraction units and coordinating logistics across floors and units with a single dedicated project manager tracking the full scope.


Call +1-844-499-0972 any time and a live dispatcher answers immediately. Your situation is assessed in real time, the nearest Grand Marsh extraction crew is dispatched, and your estimated arrival time is confirmed before you hang up.
Grand Marsh local deployment means faster arrival than regional dispatch every time.
Science-based scope assessment means the estimate is accurate, not a rough guess that changes after the fact.
We don't leave after extraction — we stay to set up drying so the project transitions without delay.



"I've dealt with water damage before and had a mediocre extraction company leave moisture behind that turned into a mold problem. When it happened again in my Grand Marsh home, I specifically asked what equipment the company used before booking. COS Water Damage Restoration mentioned their truck-mounted systems and that sold me. The difference in output versus my previous experience was obvious — they were pulling water at a rate I hadn't seen before. Moisture mapping after extraction showed everything was clear. The drying crew followed immediately. Zero mold issues six weeks later."
"As a property manager in Grand Marsh with several units, I need water extraction contractors who document everything to adjuster standards and can scale to a multi-unit event. COS Water Damage Restoration has handled two multi-unit extractions for me and both times the documentation was clean, the coordination was smooth, and the bill matched the estimate. That consistency is hard to find."
"We called COS Water Damage Restoration after another company did what I now know was an incomplete extraction of our Grand Marsh basement. When COS Water Damage Restoration arrived, their moisture mapping immediately showed saturation under the floor tiles that the first company's work had missed entirely. They extracted the residual moisture, replaced the vapor barrier in the crawlspace, and set up a proper drying program. The first company charged us and left a mold problem waiting to happen. COS Water Damage Restoration fixed it correctly."
