An incident timeline is a plain, date-ordered list of what happened, what you saw, and what you did — written by you, in your own words, as close to the events as possible. Its value is not persuasion; it is recall. Photos without dates, receipts without context, and memories of "sometime last week" are hard to use later, whether you are comparing a restoration scope, answering questions from an insurer, or simply explaining a sequence to a contractor. Build the timeline in short entries: date, time (or best estimate, labeled as such), location in the home, what you observed on the ground, and what record you created. Keep interpretations out of the event line and put them in a separate notes field.

The incident record builder lets you assemble those entries privately and export them as plain text; nothing is uploaded, stored on a server, or sent anywhere. If you have not yet thought through safe documentation, read Document water damage without putting yourself at risk first.

Start with safety and sequencing, not with the calendar

A timeline is only useful if it reflects the order federal guidance actually recommends. EPA advises that if you have evacuated, you and your family should wait to re-enter your home until professionals tell you it is safe, with no structural, electrical or other hazards, and that before cleanup you should contact your insurance company and take pictures of the home and belongings (EPA flood fact sheet). FEMA similarly advises following local officials' instructions to confirm it is safe to re-enter, and confirming that electricity and gas are shut off, with an electrician checking the house before power is turned back on (FEMA, April 2025).

So the first entries in your log may be written from outside the home, or from a hotel room: the time you noticed water, the time you left, the time you called your insurer, the time you were told the home was safe to enter. That is not a deficiency in the record. It is an accurate account of the sequence.

Two cautions belong in any timeline project. EPA warns that portable generators and other combustion devices must be used OUTSIDE and FAR AWAY from buildings because carbon monoxide is invisible and can be fatal (EPA). And EPA advises avoiding disturbance of asbestos and lead before removing wet materials such as wallboard or ceiling and floor tiles, contacting the EPA TSCA Assistance Information Service or the National Lead Information Center if asbestos or lead-based paint is known or suspected (EPA). A timeline entry like "held off on removing ceiling tiles pending advice" is a legitimate and useful record.

What to record on each line

FEMA's documentation guidance gives a workable spine. It advises taking photos and videos of the damage, including structural and personal property inside and outside the home, before discarding items, remembering the insides of closets and cabinets; recording serial numbers of large appliances; keeping receipts for replacement or repair purchases; and retaining material samples such as carpeting, wallpaper, upholstery and window treatments (FEMA). A FEMA fact sheet from a July 2025 Texas event adds labeling photos by room before removing anything, photographing appliance make, model and serial numbers, separating damaged from undamaged items for the adjuster, and keeping samples of carpet, flooring, wallpaper and drapes (FEMA fact sheet 002).

In practice, each timeline entry can carry four fields:

  • When. Date and time, or a clearly marked estimate such as "evening, exact time not noted."
  • Where. Room or area, described concretely — "north bedroom, carpet along exterior wall," not "the bad room."
  • What you observed at ground level. Visible water line on drywall, standing water depth, a smell, a sagging ceiling you saw from the doorway. Observable facts only.
  • What record exists. Photo numbers, receipt numbers, sample labels, the name of the person you spoke with and the time of the call.

Hypothetical example: "Nov 5, approx. 7:40 a.m. — Kitchen and hallway, water on floor, visible line about 6 in. up the hallway drywall. Photo set K-01 to K-14 taken before moving anything. Called insurer at 8:15 a.m., spoke with a claims representative, reference number noted. Did not enter the crawlspace." That entry is factual, bounded, and does not characterize the cause or the extent of damage.

Separate observation from interpretation

The most common way timelines lose credibility is mixing categories. "Mold started on day two" is a diagnosis; "dark discoloration visible on the baseboard on Nov 7" is an observation. EPA states that when things remain wet for more than two days they usually get moldy, and that inhaling mold can cause adverse health effects including allergic reactions (EPA) — but that is general guidance, not a finding about your home, and this site does not diagnose mold. Record what you can see from a safe position and leave the interpretation to whoever is qualified to make it.

The same discipline applies to moisture readings, drying equipment run times and any humidity numbers a contractor reports. EPA recommends keeping indoor relative humidity below 60 percent, ideally between 30 and 50 percent (EPA mold and moisture guidance), and advises drying the area quickly, within 24–48 hours if possible (EPA). Those figures are targets, not guaranteed or universal deadlines. If you log an equipment placement date and a removal date, you are recording a fact; if you log "drying failed," you are recording a judgment you are not positioned to make.

A related caution: EPA advises cleaning mold off hard surfaces with mild detergent and water rather than biocides such as bleach, and notes that mold areas larger than about 10 square feet may require professional remediation (EPA). A separate FEMA fact sheet recommends cleaning hard surfaces with bleach (FEMA fact sheet 002), which diverges from the EPA household guidance. Where sources differ, note the difference in your timeline rather than resolving it yourself. EPA also warns not to mix bleach and ammonia and not to mix cleaning products, reading and following labels in a well-ventilated area (EPA).

Log the paperwork and the conversations

Dates of calls, emails and site visits matter as much as the water. Record when you first contacted your insurer, when an adjuster inspection was requested and when it occurred, when each contractor visit happened and who attended, and when any agreement was offered. FEMA advises consulting an insurance adjuster or insurance company before signing any cleaning, remediation or maintenance agreement (FEMA). A log entry like "Nov 9, 4:00 p.m. — contractor left a one-page agreement; asked to hold until insurer contact confirmed; agreement not signed" is precisely the kind of sentence a timeline should contain.

FEMA also states that National Flood Insurance Program policies will not cover damage from mold, and strongly encourages building owners to begin cleanup and documentation immediately after a flood (FEMA). This site does not apply that statement to any individual policy or claim; coverage questions belong with your insurer. Write down what you were told and by whom, not what you concluded it means.

Denver-specific threads worth tracking

Permit and floodplain questions can occupy weeks, so they deserve their own timeline thread. Denver lists non-structural repair due to water or fire damage among commercial and multifamily projects eligible for expedited plan review, subject to conditions such as total construction valuation under $750,000, no structural work, no change of occupancy or use, and no reviews required by other agencies; it lists non-structural repairs and non-structural preparatory demolition permits among single-family and duplex projects that may qualify if of the lowest complexity and needing no other agency reviews (Denver Community Planning and Development). The reviewer makes the final determination, and projects judged too complex move to standard review.

If your property has a recorded Denver floodplain non-conversion covenant, its terms may bear on how restoration is scoped: use of enclosed areas below the Flood Protection Elevation, flood damage-resistant materials, protection of electrical and mechanical equipment, and flood openings or vents (Denver non-conversion covenant). Log the date you discovered whether such a document exists on your property — and do not interpret its insurance language yourself.

Limits of a timeline, and next steps

A timeline is a memory aid and an index. It is not an insurance determination, not a professional assessment, not evidence that any cause or cost is established, and not a substitute for inspection by qualified people. It cannot show what you did not see, and time estimates should be labeled as estimates. Keep it factual, keep the original files, and avoid retroactive edits — add corrections as new dated lines instead.

When you are ready to move from chronology to decisions, carry the timeline into Compare a restoration scope of work to check proposed work, exclusions and material handling against your record, and into Questions before restoration work starts to prepare for conversations. The incident record builder exports your entries as plain text you can keep with your own records.
