How Long Does Water Damage Restoration Take? A Bay Area Timeline

The Straight Answer

You called us at 2 AM after the water heater failed. You need to know how long this is going to take. Here is the realistic timeline.

The mitigation phase (extraction, antimicrobial application, structural drying, monitoring, dryness verification) runs 3 to 5 days for a typical Cat 1 water loss. Cat 2 gray water adds 1 to 2 days. Cat 3 sewage runs 5 to 10 days. If mold is in scope, add 3 to 7 days. Reconstruction is a separate phase that runs another 1 to 4 weeks depending on the size of the rebuild.

The clock starts the moment we are on site, but the biggest single factor is when you called. The IICRC S500 Standard for Professional Water Damage Restoration treats 48 to 72 hours as the inflection point for porous materials, which is why a 24-hour call window puts dry-in-place on the table for most Cat 1 losses and a 72-hour call window almost always shifts the conversation from drying to remediation. Speed compounds.

What Actually Happens, Day by Day

This is a typical Cat 1 water damage timeline for a 1,000 sq ft basement loss. Most Solano jobs land close to this shape.

What Slows the Timeline Down

The 3 to 5 day window above is real. Here is what pushes a job to the long end of the range or beyond.

• Hidden moisture in cavities. Water inside wall cavities, under hardwood, behind cabinets, or in subfloor takes longer to release. Thermal imaging on day 1 catches most of it, but a stubborn pocket can add 1 to 2 days.
• Sewage contamination. Cat 3 means almost everything porous comes out. Demolition + drying + rebuild instead of just drying.
• Mold growth. If you called 4+ days after the leak started, mold is already growing. The EPA's "A Brief Guide to Mold, Moisture, and Your Home" recommends professional remediation for any visible mold over 10 square feet, and the IICRC S520 Standard for Professional Mold Remediation governs containment, HEPA filtration, and post-remediation verification. Adding S520 work on top of structural drying adds 3 to 7 days minimum.
• High humidity weather. The Bay Area is usually low humidity (our friend), but during a winter atmospheric river or a summer heat dome, ambient humidity climbs and dehumidifiers work harder.
• Materials that hold water. Engineered hardwood and parquet over moisture often have to be removed because the glue and substrate trap water. Hardwood over a vapor barrier with significant exposure usually has to come out too.

What a Delayed Timeline Costs

Timeline and bill move together. Every 24 hours of delay on a Cat 1 job can push the scope (and the bill) into the next category once microbial growth starts at the 72 hour mark.

• A Cat 1 job caught fast typically lands $1,500 to $4,000. The same loss after 48 to 72 hours of sitting often crosses into Cat 2 territory ($3,000 to $8,000+) because the water is no longer clean and porous materials have to come out.
• A job that crosses into Cat 3 territory because water sat too long: $4,000 to $25,000+ depending on size, once the IICRC S500 standard kicks in and almost everything porous has to be removed.
• Add mold remediation on top if growth has started behind baseboards or in wall cavities by the time we arrive.

The cheapest restoration is the one that starts within hours, not days. For the full 2026 pricing breakdown (Cat 1 / Cat 2 / Cat 3 / mold / reconstruction) across Fairfield and Solano County, see what actually drives water damage cost.

What Makes the Job Go Faster

• You called within the first 4 hours of the loss
• Cat 1 clean water with no contamination
• Materials are open and accessible (not behind cabinets, not buried in cavities)
• Single-floor incident with no water tracking down to a lower floor
• You are not living in the affected area during drying so we can run equipment at full power without disrupting you

On a fast-track Cat 1 job called in within an hour of the loss, we have closed mitigation in 3 days flat. That is the ceiling, not the average. Plan for 4 to 5 days and treat 3 as a bonus.

Scenario worth knowing: a single-floor supply-line burst in a Suisun City or Cordelia home, caught within the first 2 hours, where the homeowner shut the main, took photos, and called immediately. That job typically wraps mitigation in 3 to 4 days because extraction, antimicrobial, and equipment placement all happen before microbial growth starts under IICRC S500's 48 to 72 hour porous-material window. The same loss called in on day 4 routinely runs 8 to 12 days because the scope picks up S520 mold remediation, drywall removal below the wet line, and reconstruction on top of the original dry-in-place plan. Whether a given wall can be dried in place at all comes down to how saturated it is and for how long; our how long wet drywall takes to dry guide covers that cutoff.

Mitigation plus reconstruction combined. Most jobs land in this range.

How Mr. Fresh Runs the Schedule

Family-owned in Fairfield since 2013. We tell you on day 1 what the realistic mitigation completion window looks like, and we update you every day. If the job is going to run longer than the original window because of something we discover (hidden moisture, mold, structural concern), you hear it from us before you have to ask.

We do not pull equipment early to make a number look better on paper. Premature equipment removal is the number-one cause of mold callbacks 3 to 6 weeks after a job. We have spent 13+ years not getting callback work, and that habit shows in how we schedule.
