What we investigate in Helena
Helena learned in 1935 what unreinforced masonry does in an earthquake, and the fault zones that shook the city then still run beneath it. Most losses we evaluate here trace to seismic movement, aging brick and stone, or wildfire pushing into the Helena Valley. A licensed engineer responds within 24 hours, with no travel charges.
The conditions we see in Helena
Helena sits where the northern Intermountain Seismic Belt deflects northwest and meets the Lewis and Clark line, a zone of older west-northwest faults. The Montana Bureau of Mines and Geology reports at least 45 potentially active faults in western Montana, and southwestern Montana carries the state's highest potential for a large earthquake. That threat is not theoretical. In 1935 an M6.2 mainshock and an M6.0 aftershock, both reaching Modified Mercalli intensity VIII, killed four people, toppled more than 200 chimneys, collapsed a wing of the new Helena High School, and destroyed the Lewis and Clark County Hospital.
Helena's core building stock is unusually old and masonry-heavy for a western city. After repeated early fires in the 1860s and 1870s, the Last Chance Gulch business district was rebuilt in unreinforced brick, stone, and granite, leaving one of the West's larger concentrations of Victorian-era masonry. That is the same construction that failed in 1935. Newer wood-framed housing now rings the historic core and climbs into the foothills and the Helena Valley wildland-urban interface, built for IECC zone 6B cold and roughly 42 inches of annual snow. Helena is in fact the Department of Energy's reference city for zone 6B.
How we help in Helena
The evaluations Helena cases usually call for
- Seismic and historic-masonry evaluation
When a brick wall cracks or a stone facade separates in Helena, the question is whether the cause is seismic movement, the age and unreinforced construction of the masonry, foundation settlement, or a building defect. Our licensed engineers read the structure and the ground together and document which one is responsible, to a standard that holds up in a claim or a courtroom.
Our structural engineering services- Foundation and water loss investigation
On foothill and valley lots we investigate frost movement, snowmelt and drainage-driven damage, and the settlement that overlaps with them. We determine whether a loss came from the ground, a construction defect, or a condition that predated the event, and we tie each conclusion to the physical evidence found at the property.

Fire origin & cause
Fire origin and cause in Helena
Wildfire is the most frequent disaster in Lewis and Clark County, and it presses right to Helena's edge. The 2012 Corral fire in the Scratch Gravel Hills burned close to 1,900 acres, destroyed four homes north of the city, and moved the county toward a wildland-urban interface zoning overlay; the 1949 Mann Gulch fire that killed thirteen firefighters burned in the Helena National Forest just north of town. When wind drives a grass or timber fire into foothill neighborhoods, the origin evidence disappears fast, and reading where a fire started is what a claim turns on.
Our NAFI-certified investigators build every determination on NFPA 921. They record the scene before it is disturbed, follow the burn and char patterns inward to the area of origin, test the electrical and mechanical systems against that origin, and work through ignition sources until the physical evidence leaves one standing, accidental or incendiary. The investigator who works the scene preserves the evidence early, writes the findings, and testifies to them at deposition and trial.
Fires we investigate
- Residential and commercial fires
- Wildland-urban interface fires
- Historic and older-building fires
- Heating-system and wood-stove fires

Common questions
Forensic engineering in Helena, Montana
A different question about your case? An engineer, not a call center, answers within 24 hours.
Is masonry cracking in Helena a seismic problem or an age problem?
It can be either, and the two interact. Helena's downtown holds extensive unreinforced Victorian masonry that is vulnerable both to slow deterioration and to shaking on the nearby faults, the same construction that failed in 1935. We evaluate the damage pattern, the construction, and the ground before assigning a cause rather than assuming one.
Can you separate wildfire damage from damage that was already there?
Yes. Distinguishing fire, ember, and smoke damage from pre-existing wear or a defect is a core part of a wildland-urban interface loss investigation in the Helena Valley, and it is usually the point a disputed claim turns on.
Do you charge travel to reach Helena?
No. We work Helena-area cases from our Omaha lab and Los Angeles office with no travel charges, and a licensed engineer responds within 24 hours.
Have a loss that needs answers?
