A burst pipe in San Anselmo can release thousands of gallons of water before it's discovered — saturating walls, subfloor assemblies, ceiling cavities, and cabinetry within hours. COS Water Damage Restoration's San Anselmo burst pipe team responds fast, locates the source, coordinates the repair, and drives the full cleanup and drying process from the moment we arrive to the final walkthrough.
The thing that separates a burst pipe cleanup done right from one done poorly is the ability to find and dry the water you can't see. Wall cavities, subfloor assemblies, and ceiling voids absorb water fast and dry slowly — and if any moisture is left behind, mold follows within days. Here's what makes COS Water Damage Restoration the right call in San Anselmo.
Burst pipe water in San Anselmo properties follows the path of least resistance through wall framing, floor assemblies, and ceiling cavities — appearing on the surface far from the rupture point. Our FLIR thermal cameras trace moisture migration through structural assemblies, ensuring we find every saturated area before drying equipment is staged. Drying a room without mapping it first means leaving wet assemblies behind walls that will grow mold within 48-72 hours.
Our San Anselmo burst pipe response crew targets arrival in 60 minutes or less from your call. Burst pipe water is Category 1 — clean water from the supply side of your plumbing — which gives us a short window to extract and dry before it degrades into Category 2. Speed of arrival is the single biggest driver of total damage scope and total project cost.
Our San Anselmo team arrives, secures the water source (shutting the main if necessary), and directly coordinates with a licensed plumber to complete the pipe repair before cleanup begins. We've established working relationships with licensed plumbing contractors across San Anselmo and CA — so you're not trying to find a plumber at 2am while water is still running.
Accurate documentation from day one leads to faster claim settlements and fewer supplemental disputes.
From the moment we arrive at your San Anselmo property, COS Water Damage Restoration manages the complete scope of burst pipe recovery — source control, extraction, wall cavity access, structural drying, and rebuild. Every phase under one crew, one scope, one invoice.
The first priority when our San Anselmo crew arrives is stopping the water source. If the affected valve or supply line is accessible, we isolate it directly. If the break is inside a wall or in an inaccessible location, we shut the main supply and work with a licensed plumber to locate and repair the rupture before cleanup begins. Stopping the source is not the cleanup company's job in a literal trade sense — but it's absolutely the first 15 minutes of our time on every San Anselmo burst pipe call, and we coordinate it aggressively.
Complete extraction cuts drying time significantly and reduces the risk of secondary damage.
FLIR thermal cameras and calibrated pin-type and non-penetrating moisture meters map the full extent of water migration through your San Anselmo property's structural assemblies. Burst pipe water moves through wall cavities and floor systems rapidly and can saturate framing far from the visible wet surface. Our San Anselmo moisture mapping creates a documented baseline — showing exactly where the water went, how saturated it is, and how far from the rupture point the damage extends. This map drives the drying scope and the insurance documentation.
Wall cavity drying is where most burst pipe jobs either succeed completely or fail at the last 10%.
Insurance complexity is handled by our team, not handed off to you.
Once every structural assembly has been confirmed dry by instrument reading, our licensed San Anselmo reconstruction team rebuilds: drywall replacement and finish, fresh paint, flooring reinstallation, baseboard and trim, and any cabinetry affected by the pipe location. If the pipe burst behind cabinetry, we coordinate cabinet reinstallation after the repair is complete. All reconstruction work uses the same Xactimate line-item format as the mitigation scope — so your insurer sees one integrated claim file, not separate invoices from separate contractors.

"A pipe in our kitchen wall burst while we were at work and water ran for several hours before a neighbor spotted it. COS Water Damage Restoration arrived in under an hour, shut the water source, had a plumber at the house within 90 minutes of their arrival, and started extraction before the plumber finished the repair. The thermal imaging they did showed water migration we never would have found — all the way down through the subfloor into the crawlspace below. Two weeks later, everything was dry, rebuilt, and our insurance claim was settled. They handled all of it."
"What impressed me most was the moisture mapping session. Our burst pipe was in the second-floor bathroom, and COS Water Damage Restoration's tech found water in the wall cavity adjacent to the pipe, inside the ceiling of the first floor below, and along a wall run in the living room — none of which had any visible surface water. They set up drying for all of it, hit it with daily readings, and everything came back confirmed dry before reconstruction started. That level of thoroughness is exactly what you want from a company doing this type of work."
"Three years after our San Anselmo burst pipe incident handled by COS Water Damage Restoration, there has been no mold, no musty odor, and no re-emergence of moisture. They dried it correctly the first time. That's ultimately what you're paying for."
