When water damage hits your home or business in Sioux Falls, you need a local crew that can actually show up fast — not a call center routing your emergency to a contractor two hours away. COS Water Damage Restoration's Sioux Falls-based Water Damage Repair teams are licensed, certified, and ready around the clock.
Positioned in Sioux Falls for fast local response every time.
Every technician holds current WRT certification — the industry standard.
Written estimate in your hands before any work begins.
We build your claim file and deal with your adjuster directly.
COS Water Damage Restoration's Sioux Falls team isn't a remote dispatch forwarding your call to whoever happens to be available — we maintain a dedicated local operation in Sioux Falls with crew members who live and work in the community, understand the local building stock, and know the fastest routes to your neighborhood at any hour.
We bring enterprise-grade extraction and drying equipment to every Sioux Falls job — not the rental-store grade equipment that leaves moisture in wall cavities and under flooring that causes mold weeks after the job was supposedly done.
Our reputation in Sioux Falls is built on one job at a time — and we protect it by treating every property we work in with the same professionalism we'd want if it were our own home or business being restored.

Every service listed below is available 24/7 in Sioux Falls — no wait lists, no "call back during business hours," no sending you to a subcontractor we can't vouch for.
When a pipe bursts, a basement floods, or a storm drives water into your Sioux Falls home or business, the standing water you're looking at is only the beginning of the problem. Sioux Falls's Water Damage Repair emergency calls include everything from clean water supply line failures to contaminated sewage backflows, and our crews are trained and equipped for every category of water damage — with the right PPE, containment protocols, and extraction methods for each situation.
Our residential restoration teams in Sioux Falls are experienced across the full range of home types found in the area — older homes with original hardwood and plaster, newer construction with engineered materials and finished basements, and everything in between. Daily check-ins from your project manager keep you informed throughout the drying cycle, and reconstruction doesn't begin until documented moisture readings confirm every structural assembly has reached target levels.
Water damage to a commercial property in Sioux Falls isn't just a property issue — it's a business interruption event that starts costing revenue from the moment the damage begins. Commercial jobs in Sioux Falls receive a dedicated project manager who handles all carrier communication, adjuster scheduling, supplement filing, and daily progress reporting — leaving business owners and property managers free to focus on their operations rather than managing a restoration project.
Mold is the almost-inevitable consequence of water damage that wasn't addressed quickly or completely — and in Sioux Falls's climate, wet building materials can support mold growth in as little as 24 to 48 hours after initial exposure. We never treat mold as a surface problem or attempt to cover it with encapsulants when removal is required — our remediation approach is based on assessment of the affected material and what the manufacturer and IICRC standards recommend for each scenario.
Building new drywall or flooring over materials that are still holding excess moisture leads to cracking, warping, fastener failure, paint peeling, and eventually mold growth — which is why our Sioux Falls drying crews take measurement seriously and don't sign off on a project until the numbers confirm completion. Daily moisture readings are taken at consistent sensor points throughout the drying cycle and recorded in a written log that documents the progress of drying over time — useful for your insurance file and for your own records.
COS Water Damage Restoration takes the second challenge entirely off your hands — from the first notice of loss through final settlement — so you can focus on your family and your recovery rather than on paperwork, phone calls, and adjuster negotiations. If your adjuster's initial settlement offer doesn't fully account for the documented scope of loss, we prepare and file a supplement with supporting evidence — a step that many homeowners don't know they can take and that frequently results in additional covered compensation.

Thermal imaging cameras reveal moisture in wall assemblies and under flooring that isn't yet visible on the surface — giving us a complete picture of the damage before we build the response plan.
With the scope confirmed and your approval in hand, extraction begins immediately using the highest-capacity equipment appropriate for the situation.
A calculated drying plan is implemented immediately following extraction — air movers and dehumidifiers placed based on psychrometric data specific to your Sioux Falls property's materials and conditions.
Antimicrobial treatment is applied to all moisture-exposed surfaces as a standard preventive step — stopping mold colonization before it can take hold in your Sioux Falls property's structural assemblies.
We coordinate the reconstruction scope with your insurance carrier's supplement process before work begins, so funding is in place and there are no payment delays.
When a restoration company sends a crew to your Sioux Falls property who has never worked in the area, the difference in performance is real — and it shows up in ways that matter: slower navigation to your address, unfamiliarity with local building code requirements that affect how drying and reconstruction are approached, no relationship with local supply vendors that allows materials to be sourced quickly, and no reputation to protect within the community they're serving.
Sioux Falls's mix of housing stock — from older historic homes to newer construction developments — presents a range of material and structural challenges that our crews encounter regularly.
Sioux Falls's weather patterns contribute to the types of water damage events we see most frequently here — and our crews are prepared for the specific scenarios that Sioux Falls property owners face more often than those in other markets.
Water damage restoration costs in Sioux Falls vary based on several factors: the volume of water, the category of water (clean vs. contaminated), the materials affected, the square footage involved, and the extent of mold risk.

Read what Sioux Falls customers consistently say about response time, professionalism, pricing, and results.
"We had a washing machine overflow that soaked the laundry room and wicked into the adjacent bedroom overnight before we noticed it. I found it in the morning and called COS Water Damage Restoration immediately. Their crew was at my Sioux Falls house in 55 minutes — which was remarkable given that I called at 7 a.m. on a Saturday. They found moisture under the bedroom baseboard that I never would have caught, set up drying equipment that ran for five days, and the project manager called me with readings every morning. No mold, no lingering smell, and the claim went through without a single request for additional documentation. Absolute professionals."
"The burst pipe situation in our Sioux Falls rental unit was a nightmare — the tenants called me at midnight, the unit was partially flooded, and I had no idea how bad it was. COS Water Damage Restoration's crew was on site before I could even get there myself. By the time I arrived, extraction was underway and the project manager was already walking through the damage assessment with photos. I had a full scope and estimate in my email before 2 a.m. The restoration was completed on schedule, within the estimated cost, and my tenant was back in the unit within two weeks. Outstanding."
"Mold found during the renovation of our Sioux Falls home led us to COS Water Damage Restoration for remediation. The discovery was stressful — we didn't know how extensive it was or what it meant for the timeline of our project. The COS Water Damage Restoration team came in, assessed it thoroughly, explained exactly what they found and what the IICRC-compliant remediation process looked like, and completed the job on time. The post-remediation air testing came back clear, the report they provided satisfied our contractor and our insurer, and we were back on schedule within a week. Professional from beginning to end."
