Granite Bay property owners dealing with water damage have one smart move: call COS Water Damage Restoration and get a local crew on site within the hour. COS Water Damage Restoration's Granite Bay-based Water Damage Repair teams are on standby 24/7 with equipment staged and crews briefed.
Local Granite Bay crews on standby — not dispatched from out of the area.
Certified professionals, not unlicensed laborers.
Written estimate in your hands before any work begins.
Works with all major CA insurers.
COS Water Damage Restoration's Granite Bay team isn't a remote dispatch forwarding your call to whoever happens to be available — we maintain a dedicated local operation in Granite Bay 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 Granite Bay 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 Granite Bay 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.

Our integrated service model means Granite Bay property owners have one phone number, one point of contact, and one company responsible for the outcome from start to finish.
Our truck-mounted extraction systems can pull high volumes of water in a fraction of the time it would take with consumer-grade equipment — getting the visible water out fast while our moisture detection team maps the water you can't see yet. After extraction, we don't pack up and leave — we immediately stage the drying equipment that will begin drawing moisture from structural assemblies before mold has a chance to gain a foothold.
For Granite Bay homeowners, water damage is one of the most disruptive and stressful events a family can face — and the quality of the restoration company you choose determines not just how fast you get back to normal, but how thoroughly the problem is actually resolved. For Granite Bay homeowners with original hardwood floors, our floor mat drying systems often allow us to dry hardwood in place rather than requiring replacement — a significant cost savings and a result that preserves the character of your home.
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. Whether the loss is a small office suite or an entire floor of a commercial building, COS Water Damage Restoration's Granite Bay commercial team has the experience and equipment to handle it.
COS Water Damage Restoration's mold remediation team in Granite Bay follows IICRC S520 protocols — the industry standard for safe and effective mold removal — and documents every step of the process so you have a verifiable record of what was found, what was done, and what clearance testing confirmed. HEPA filtration, containment barriers, negative air pressure, and proper PPE are standard on every Granite Bay mold remediation job — protecting your household members and our crews from exposure to dislodged spores during the removal process.
Professional structural drying in Granite Bay is the phase of water damage restoration that most homeowners understand least — and the one that most directly determines whether the restoration holds up long-term or creates ongoing problems. 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. We've worked with every major insurer serving Granite Bay and Granite Bay, CA 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.

Your Granite Bay home or business deserves the professionalism that certification represents.
Better tools mean faster drying, more thorough moisture removal, and far less risk of mold development or structural damage after the job is complete.
Our Granite Bay claim team knows the carriers serving this market, the documentation those carriers require, and how to build a file that moves through underwriting quickly and pays out what you're owed.
Five-star reviews are earned, not purchased — and they reflect what happens when every technician takes personal pride in the outcome of every job.
No being transferred between departments, no explaining your situation to a new person every time you call, no wondering who's responsible.
Our process eliminates the guesswork and the anxiety of not knowing what comes next — because you deserve to know exactly what your restoration team is doing and why at every step.
You receive your crew's estimated arrival time before you hang up, and a direct callback number if anything changes en route.
Our crew arrives at your Granite Bay property and immediately begins a systematic assessment — identifying every water entry point, mapping moisture migration with detection instruments, and classifying the water category (clean, gray, or black water).
Contaminated water scenarios activate full containment protocols — antimicrobial pre-treatment, barrier installation, and regulated disposal procedures to protect your household from cross-contamination.
Equipment stays until documented readings confirm completion — not until a certain number of days has passed.
A written remediation report is issued that documents every action taken and every clearance measurement recorded.
Our licensed reconstruction team handles all Granite Bay rebuilding work — drywall, flooring, painting, trim, and structural repairs — under the same project management as the restoration phase.
That local familiarity translates into faster arrival, fewer logistical delays, better-informed scope assessments, and the kind of personal accountability that comes from knowing your work might be reviewed by someone who lives down the street.
Our Granite Bay technicians bring this material-specific knowledge to every assessment and use it to build drying plans that work for your specific property rather than applying a generic template.
That local context makes our assessments more accurate, our response timelines more reliable, and our client communication more informed.

Read what Granite Bay customers consistently say about response time, professionalism, pricing, and results.
"I run a small business in Granite Bay and had a toilet supply line failure on a Sunday night that flooded my office suite and spread into the common hallway. I called COS Water Damage Restoration, who answered immediately, and had a crew at the building in under an hour. They worked through the night to extract the water and set up drying equipment before we opened Monday morning. My employees came in to a building that was functional — inconvenient, but operational. The insurance claim was handled entirely by their coordinator and settled in less than three weeks. I recommend them to every business owner I know in Granite Bay."
"The burst pipe situation in our Granite Bay 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 Granite Bay 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."
