Water damage restoration in Austin
Travis County records about 5.5 flood events a year, among the highest of the cities covered here. Once water is inside, EPA puts the drying window at 24 to 48 hours.
What usually causes it in Austin
- 36.8 nights a year below freezing — few enough that plumbing is rarely built around it, and cold enough that it happens.
- Water from outside is a real route here — FEMA rates Travis County for hurricane and coastal flooding, so CDC's floodwater rules apply if that is what came in.
- Only 15.6% of homes predate 1980 — age of plumbing is rarely the explanation here.

What the record says about Austin
Austin sits between two patterns. It is cold enough at night for supply lines to fail — more freezing nights than Dallas — and it sits in terrain where heavy rain moves fast across ground that does not absorb it.
Which one it was changes everything about the response. Clean water from a line is dried and most material is saved. Water that came across the ground from outside is a cleanup first, and CDC's advice there is to stay out of it rather than to start mopping.
If water arrived at ground level during a storm, say so when you describe it. It is the single most useful thing a provider can know before arriving.

The first 48 hours in Austin
The hours come from EPA and CDC, and they do not change with the weather.
- 0–2 h
Safety first, then the source
- If there is standing water and the main power switch is reachable from a dry spot, CDC says to turn the power off. If you would have to step into the water to reach it, call an electrician instead.
- 2–24 h
Water out, air moving
- CDC: clean up and dry out the building fully and quickly, within 24 to 48 hours of the flood.
- 24–48 h
The window is still open
- EPA: if wet or damp materials or areas are dried 24 to 48 hours after a leak or spill happens, in most cases mold will not grow.
- 48+ h
A different job now
- Past this point the question changes from drying to what has already grown.
- EPA puts the line at about 10 square feet: under roughly a 3 ft by 3 ft patch, in most cases a homeowner can handle the job; above it, the guidance is different.
Austin questions
Five flood events a year sounds like a lot. What counts as one?
FEMA's National Risk Index counts recorded flood events across the whole county, not floods at your address. A county that is large and has several creeks running through developed land accumulates events quickly without any individual property flooding often.
Water came in at ground level during a storm. Is drying enough?
Probably not on its own. Water that arrived from outside falls under CDC's floodwater guidance, which is to stay out of it where possible and to wear rubber boots, rubber gloves and goggles if you must enter. The cleanup is a separate question from the drying.
Does Austin get cold enough for frozen pipes?
The record says about 36.8 nights a year at or below freezing at Austin-Bergstrom — more than Dallas, and enough that it is a regular cause rather than an exotic one.
What does a referral cost?
Nothing, and it commits you to nothing. What the work costs depends on how much is wet and what has to come out; published national ranges and their sources are on the cost page.
