When water damage hits your home or business in Marietta, 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 Marietta-based Water Damage Repair teams are licensed, certified, and ready around the clock.
Positioned in Marietta for fast local response every time.
Certified professionals, not unlicensed laborers.
No hidden fees, no last-minute line items.
We build your claim file and deal with your adjuster directly.
We've handled everything from flash-flood basement extractions in Marietta's older neighborhoods to multi-floor commercial water events in newer construction, and every job has reinforced the same core truth: speed and expertise make the difference between a manageable repair and a catastrophic rebuild.
Every technician who arrives at your Marietta property carries current IICRC WRT (Water Damage Restoration Technician) certification, a background-check clearance, and familiarity with the specific materials and construction methods common in Marietta's housing stock.
Our reputation in Marietta 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 Marietta — no wait lists, no "call back during business hours," no sending you to a subcontractor we can't vouch for.
In Marietta, our emergency extraction crews maintain ready-to-deploy status every hour of every day — because the fastest response to flooding directly determines how much of your property can be saved. Marietta'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 Marietta 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. Our moisture mapping process identifies every area where water has penetrated — not just what's visible on the surface, but the moisture inside wall assemblies, under flooring systems, and in ceiling cavities — so that the drying plan we build addresses the complete scope of moisture, not just the obvious puddles.
We work in occupied buildings, schedule around your operating hours when it's possible to do so safely, and produce the detailed loss documentation that commercial insurance adjusters require — all as standard practice, not a premium option. Commercial jobs in Marietta 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 Marietta's climate, wet building materials can support mold growth in as little as 24 to 48 hours after initial exposure. Post-remediation air quality testing provides objective confirmation that the remediation was successful, and the written clearance report we issue becomes part of your property's maintenance record.
The goal of structural drying isn't just to make the air feel dryer or to run fans for a few days — it's to return every material in the affected area to its documented equilibrium moisture content, verified by calibrated instruments, before any reconstruction begins. We deploy industrial LGR dehumidifiers and high-velocity air movers in a calculated configuration based on the square footage, material types, and psychrometric conditions specific to your Marietta property — not a one-size-fits-all equipment drop.
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. We've worked with every major insurer serving Marietta and Marietta, SC and understand the specific documentation standards, turnaround expectations, and adjuster assignment processes that each carrier follows — knowledge that translates into faster claim approvals and fewer disputes.

Older Marietta homes with original hardwood flooring, plaster walls, and basement moisture histories require different drying strategies than newer builds with engineered hardwood, drywall, and open-plan floor plans that allow air movement differently.
That local context makes our assessments more accurate, our response timelines more reliable, and our client communication more informed.
Water damage restoration costs in Marietta 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.

Real reviews from Marietta, SC property owners who called COS Water Damage Restoration when water threatened their homes and businesses.
"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 Marietta 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 Marietta 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 Marietta 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."
