Walla Walla is the seat of its county and one of the older towns in the inland Northwest, with brick commercial blocks downtown, a former 1890 hospital converted to apartments, and neighborhoods such as Blalock, South Ninth and Germantown that grew up around gardens and creeks. Older plumbing and masonry shape a lot of the damage calls here.
Fire & Water Energy handles the phone side only, passing callers along as referrals rather than doing repairs. Ring (866) 937-3230 and we will see whether an independent restoration contractor serving Walla Walla and College Place can take the job; that depends on which local outfits have openings. Take a look at how it works or the referral disclosure any time.
Mill Creek, rain-on-snow events and valley freezes
Mill Creek flooded the city 15 times between 1878 and 1931. The 1931 flood spilled into Walla Walla and College Place, and that disaster led to the Army Corps of Engineers' Mill Creek project, which diverts high winter flows into Bennington Lake and limits what passes through town. In February 1996 a rain-on-snow storm filled the reservoir to 97 percent, and in February 2020 the creek set a new high-water record and did significant damage in the valley, though the city itself stayed dry.
Walla Walla County's FEMA major disaster declarations since 2000 cover record and near-record snow in 2009 (DR-1825), severe winter storms and flooding in 2017 (DR-4309), and the 2020 storms, flooding and landslides (DR-4539). The valley also sees killing freezes roughly every six or seven years, such as in 2004 and November 2010, with a record low of −24°F.
Why pipes, roofs and old plumbing fail here
The city gets under 19 inches of precipitation a year and only a few inches of snow, so many homes are not built with deep cold in mind. When a hard freeze arrives, lines in crawlspaces and outside walls can split. Older houses and converted historic buildings add galvanized supply pipes, cast-iron drains and patched roofs to the risk list, and summer heat that tops 100 degrees keeps cooling systems and their condensate lines working hard.
A contractor handling water damage restoration in Walla Walla will normally stop the leak, extract water, open up wet cavities where needed and dry the structure while tracking moisture readings. Then comes water damage repair to rebuild. Also useful: burst pipe water damage and ceiling water damage repair.
Federal disaster declarations that included Walla Walla County
FEMA records show Walla Walla County was included in 3 major disaster declarations for weather or fire events from 2000 through 2026 (2 flood, 1 severe storm, by FEMA incident type). Declarations are made at the county level, so they do not mean every neighborhood in Walla Walla was affected. The most recent:
- 2020 – Severe Storms, Flooding, Landslides, and Mudslides (DR-4539)
- 2017 – Severe Winter Storms, Flooding, Landslides, Mudslides (DR-4309)
- 2009 – Severe Winter Storm and Record and Near Record Snow (DR-1825)
Source: OpenFEMA Disaster Declarations Summaries, retrieved 2026-10-10. Counts include major disaster (DR) declarations with hurricane, flood, severe storm, tropical storm, fire, tornado, coastal storm, winter or ice storm, mudslide and dam/levee incident types.

Fire, soot and smoke in older buildings
Fire is part of local history; the city's old Chinatown was largely destroyed by one. In older homes and brick downtown buildings, smoke tends to travel through hollow walls, chases and old ductwork, so odor can show up rooms away from where a fire started. Plaster, wood trim and masonry each need different cleaning approaches.
Fire cleanup firms usually secure openings, remove debris, clean soot surface by surface, treat odor with air filtration and dry out the water used to put the fire out. Details are on our fire damage cleanup and smoke damage cleanup pages.
Flood and storm cleanup when the creeks rise
Several creeks meander through town before joining the Walla Walla River, and the 2017 and 2020 declarations both involved flooding. Even with the flood-control system holding Mill Creek in check, heavy rain on melting snow can overwhelm smaller channels, yards and basements, and landslides were part of the 2020 event across the county.
Floodwater is assumed to carry contaminants, so soaked carpet, pad, insulation and lower drywall are generally cut out and the remaining structure cleaned and dried. Our flood damage restoration and basement flood cleanup pages explain the process.
Mold in a dry climate is still possible
Walla Walla is sunny and dry for much of the year, but mold only needs a material that stays damp. Hidden leaks under sinks, a crawlspace wetted by a burst pipe, or a basement that took in water during a winter flood can all grow mold within days.
The EPA's rule of thumb is that a homeowner can often tackle under about 10 square feet after fixing the moisture problem. Larger growth, mold in walls or ducts, or contamination tied to floodwater is a job for a remediation company with containment and HEPA filtration. See mold remediation.
What to do first in Walla Walla
- Call 911 for a fire, a gas smell, an injury or a downed power line, and step outside if the structure looks compromised.
- Turn off the main water valve when a pipe lets go, and keep clear of wet floors near outlets or appliances.
- Watch county emergency management updates and local news while a winter high-water event is underway.
- Before cleaning, record the damage with dated photos and notes. What your policy pays for depends on its wording; your insurer or agent can clarify.

Walla Walla restoration FAQs
Does Mill Creek still flood Walla Walla?
The creek flooded the city often before 1931, but the Army Corps' flood-control project and Bennington Lake have kept the city from flooding in major events since, including 1996 and the record high water of February 2020. Damage still occurred elsewhere in the valley in 2020, and small creeks and basements can take on water in heavy storms.
How cold does it get in the Walla Walla Valley?
Most winters are mild for the latitude, but killing freezes hit about every six or seven years and the record low is 24 below zero. Those cold snaps are when exposed pipes in crawlspaces and garages tend to burst.
Does an older Walla Walla house need a different drying approach?
It can. Plaster walls, old wood floors and older pipe materials dry and repair differently than modern drywall and PEX. Ask any contractor how they plan to dry and protect original materials before work starts.
Do you send someone out to my house?
No, nobody is dispatched by us, since Fire & Water Energy works purely as a referral service for the valley. Calling (866) 937-3230 lets us try to connect you with an independent contractor that works in the Walla Walla area, and you deal with that company directly.
