Find the guide for the situation you are actually in

These are written from the jobs we run, not from a keyword list. If water is active right now, skip the reading and call — every guide here says the same thing in its first paragraph.

It is happening now. Start with what to do immediately after water damage for the first-hour sequence, then the guide matching your cause — a burst pipe, a sewage backup, a flooded lower level or a roof leak mid-storm.

It has happened and now you are dealing with the aftermath. The three questions everyone asks are answered in what restoration actually costs, what California insurance covers and how long the process takes.

You suspect something but cannot find it. Read how to detect hidden water damage and the hidden dangers of water damage mold. If you are trying to stop the next one, the prevention checklist and storm preparation guide are the two with the best return on an afternoon of work.

How these are written

Where the numbers in these guides come from

Most restoration content on the internet is a national average rewritten for a city name. These are written from jobs run out of 550 Allerton Street, which is why the figures are specific enough to be wrong if they were invented.

Every cost figure across these 15 guides comes from one source and appears identically everywhere it is used: mitigation at $3 – $7.50 per square foot depending on water category, most complete jobs between $1,384 and $6,387, average around $3,867. If we revise those, they change on all 15 guides and every service page at the same time. You will not find one number in an article and a different one on the page it links to.

Drying times are stated as ranges because they genuinely are ranges — three to five days for framing and drywall, seven to ten for slabs, plaster, solid hardwood and below-grade spaces, longer again on bayfill where the water table works against you. Any guide promising a fixed number of days is describing a billing schedule, not a drying plan.

Insurance guidance describes how California policies generally treat sudden and accidental failures versus gradual leaks and deferred maintenance. It is written to help you understand what your adjuster is weighing, and it deliberately stops short of promising an outcome on your specific policy — which nobody who has not read it can honestly do. Every guide is reviewed by our IICRC-certified project managers before it is published, and carries its own published and last-reviewed dates.

The short answers

Six questions, answered in a sentence each

If you only came for one fact, it is probably one of these. The linked guide has the reasoning behind it.

How fast do I need to act?
Mould can begin growing on damp material within 24 to 48 hours, and extraction in the first hour is what decides whether a floor is dried or replaced.The first-hour sequence
What will this cost?
Most complete jobs land between $1,384 and $6,387, averaging around $3,867, priced per square foot by water category.Full cost breakdown
Will insurance pay for it?
Sudden and accidental failures usually yes; gradual leaks and deferred maintenance often not; rising water from outside normally needs separate flood cover.California coverage in detail
How long will the whole thing take?
Three to five days of drying for framing and drywall, seven to ten for slabs and hardwood, then reconstruction on top of that.Day-by-day timeline
Can my hardwood floor be saved?
Often, if specialty drying mats go down within days rather than weeks — cupping is recoverable far more often than homeowners are told.What decides it
How do I stop this happening again?
Supply lines, water heater age, and gutter and drainage capacity before the wet season account for most of the calls we take.Prevention checklist

FAQ

About these guides

Who writes these guides?

They are written from the jobs we run, and reviewed by our IICRC-certified project managers before publication. Where a guide states a drying time, a cost range or a material behaviour, it reflects what we see on Peninsula properties rather than a national average copied from somewhere else. Where something varies by address, the guide says so instead of averaging it away.

Should I read a guide or just call?

Call, if water is moving right now. Every emergency guide on this site says the same thing in its first paragraph, because reading is not what the first hour is for. The guides are written for the other two situations: working out what happened after the fact, and stopping the next one.

Are the cost figures in these guides real?

They are our own published figures, used consistently across the whole site: roughly $3 to $4 per square foot for clean water, $4 to $7 for gray water, $7 to $7.50 for Category 3, with most complete jobs landing between $1,384 and $6,387. A guide will never quote you a firm number for your property, because that depends on what is wet behind the walls.

How often are the guides updated?

Each guide carries its own published and last-reviewed date, and the pricing, insurance and response-time figures are drawn from the same source as the rest of the site, so they change everywhere at once rather than drifting page by page. Storm and flood-risk guidance is revisited ahead of each wet season.

Can I use these to argue with my insurance adjuster?

They will help you understand the vocabulary — sudden versus gradual, water category, damage class, mitigation versus reconstruction — which is most of what makes a claim conversation difficult. What actually moves an adjuster is documentation from the property itself: the photo record, the daily moisture logs and an itemised scope. A guide cannot substitute for that.
