COS Water Damage Restoration's Lagunitas-based Water Damage Repair teams are on standby 24/7 with equipment staged and crews briefed.
Local Lagunitas crews on standby — not dispatched from out of the area.
Every technician holds current WRT certification — the industry standard.

Water damage in Lagunitas moves on its own timeline, which is why our local dispatch operation stays fully staffed around the clock, every day of the year — so that when the call comes in at 2 a.m., the crew heading to your door is already mobilized.
Every technician who arrives at your Lagunitas 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 Lagunitas's housing stock.
COS Water Damage Restoration has earned the trust of Lagunitas homeowners, landlords, property managers, and commercial facility owners because we consistently do what we say we'll do: we arrive when we say we'll arrive, we provide the estimate we quoted, we complete the documentation we promised, and we stand behind the work with a written satisfaction guarantee.

COS Water Damage Restoration provides comprehensive Water Damage Repair in Lagunitas — covering every phase from emergency extraction through mold remediation, structural drying, and full reconstruction, all managed by our local Lagunitas crew.
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. Call +1-844-499-0972 the moment you discover water in your Lagunitas property — our dispatcher will guide you through immediate protective steps while our crew is already on the way.
Our residential restoration teams in Lagunitas 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.
COS Water Damage Restoration's commercial restoration operation in Lagunitas is built for speed and scale — with crew sizes that grow to meet the scope of the loss, equipment inventories that cover large square footages, and project management that keeps business owners and property managers informed without requiring them to micromanage the process. Whether the loss is a small office suite or an entire floor of a commercial building, COS Water Damage Restoration's Lagunitas commercial team has the experience and equipment to handle it.
Many Lagunitas homeowners discover mold weeks or months after a water event that they thought had been fully addressed, because invisible moisture remained in wall cavities, beneath flooring, or in attic insulation after a surface-only cleanup. HEPA filtration, containment barriers, negative air pressure, and proper PPE are standard on every Lagunitas mold remediation job — protecting your household members and our crews from exposure to dislodged spores during the removal process.
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 Lagunitas drying crews take measurement seriously and don't sign off on a project until the numbers confirm completion. 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 Lagunitas 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. Our approach to insurance coordination in Lagunitas is built on the principle that your policy was paid to cover a genuine loss, and our job is to make sure it pays what it's supposed to.

Here's exactly what happens when you call COS Water Damage Restoration for water damage in Lagunitas, from the moment the phone rings to the day we hand your property back.
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 Lagunitas 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).
We extract completely and transition directly to drying setup without an overnight gap where mold begins to grow.
Equipment stays until documented readings confirm completion — not until a certain number of days has passed.
Pre-existing or emerging mold growth is addressed by our IICRC-certified remediation specialists with containment, HEPA air scrubbing, material removal, and clearance testing.
Our licensed reconstruction team handles all Lagunitas 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.
Older Lagunitas 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 Lagunitas 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. Most residential water damage events in Lagunitas fall within a range that homeowner insurance covers significantly, which is why our insurance coordination service is so valuable — we help make sure your policy pays what it should so your out-of-pocket is minimal. Call +1-844-499-0972 for a free on-site estimate with no obligation to proceed — we'll give you a clear picture of scope and cost before you commit to anything.

These are the experiences of your neighbors in Lagunitas — unedited, firsthand accounts of working with our local restoration team.
"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 Lagunitas 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 Lagunitas 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 Lagunitas 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."
