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 Alton 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.
High-volume truck-mounted extractors for large-scale flooding events in Alton.
FLIR thermal cameras reveal moisture in walls and under floors invisible to the naked eye.
Daily readings tracked until drying targets are met.
Handles water at depths portable extractors cannot.
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 Alton extraction service different.
Every Alton 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.
Our Alton crews are positioned locally — not dispatched from a regional hub. We target 60 minutes on-site from your call, with equipment staged during transit so we're working within minutes of arrival.
Science-based extraction and drying produces better outcomes than intuition-based approaches.
No estimates given over the phone without seeing the scope. No surprises after the work is done.
COS Water Damage Restoration's Alton Water Extraction team handles every water extraction scenario — from residential flooding to large commercial events — with equipment and technique matched to the specific situation.
Truck-mounted extraction systems — the most powerful commercial water removal equipment available — are deployed for high-volume flooding events in Alton: storm flooding, major pipe failures, and large appliance failures that release significant water rapidly. Truck-mount output far exceeds portable units, reducing total extraction time and limiting saturation of structural assemblies.
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.
Original hardwood flooring in Alton properties responds differently to water extraction than vinyl or tile — the drying window is narrower, the risk of cupping and buckling is higher, and the technique must account for the seasonal moisture content of the wood at the time of loss. Our Alton technicians assess hardwood conditions during extraction and immediately plan for mat drying or board-by-board evaluation based on what the moisture meters show.
Below-grade water extraction in Alton requires submersible pump capability for standing water, then portable extractor transition for residual moisture, and finally vapor barrier inspection and replacement to prevent recurring moisture accumulation. Confined space protocols apply in crawlspaces with limited access — our Alton crew carries the right equipment for each below-grade scenario.
Carpet and pad systems hold water effectively — up to a gallon per square yard — and standard extraction passes often leave substantial moisture in the pad beneath. Our Alton crew uses weighted extraction tools that apply appropriate pressure during the extraction pass, then evaluates whether pad salvage or replacement is more cost-effective based on the category and saturation level of the water.
Commercial and multi-family properties in Alton present extraction challenges that residential scenarios don't: larger square footage, multiple affected units, infrastructure protection requirements, and business interruption cost. Our Alton 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.


Live Alton dispatch — no voicemail, no hold queue, no automated menu.
Our crew arrives with truck-mounted and portable extraction equipment configured for your reported scenario. Equipment is staged during transit so the crew is productive immediately on arrival — not spending 20 minutes unloading and setting up in your driveway.
Thermal imaging and moisture mapping precede extraction — so the scope is fully known before equipment runs. A written estimate is reviewed with you and approved before work begins. No extraction happens without your sign-off on the scope and cost.
We don't leave after extraction — we stay to set up drying so the project transitions without delay.



"The thermal imaging step was what impressed me most. Our Alton property looked dry to me, but their camera showed moisture migration behind the baseboard on two walls I never would have suspected. If that had been left in place and the drying missed it, we'd have had mold within the month. Very glad they do this as standard procedure."
"As a property manager in Alton 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."
"The written estimate before extraction was a first for me — every other contractor I've used has just started working and handed me a bill. COS Water Damage Restoration's pricing conversation happens before the equipment turns on. That's the right way to do it and I won't use anyone who doesn't operate this way."
