What we investigate in Nashua
Nashua sits where the Nashua River meets the Merrimack, and the losses we evaluate here run from river flooding to deep frost, ice-dam damage, and fires in aging mill-era buildings. We determine what actually failed and document it to a standard that holds up, and a licensed engineer responds within 24 hours.
The conditions we see in Nashua
Nashua stands at the confluence of the Nashua and Merrimack Rivers, and river flooding is part of the city's record. The Northeast River Forecast Center documents the March 1936 flood as the worst on record, raising the Nashua River about 12 feet and damaging the mills; the city now depends on a Merrimack levee and hydro dams on the Nashua River. Southern New Hampshire also takes heavy nor'easter snow and ice, which loads roofs, drives ice dams, and puts foundations through deep seasonal freeze-thaw.
The building stock reflects the mill history. The Nashua Manufacturing Company millyard is substantial brick built largely between 1823 and 1883, with wood-frame mills added from 1899 to 1905, much of it now converted to apartments and mixed use. Around it sit dense downtown blocks and 19th and early-20th-century wood-frame worker housing, along with postwar and suburban frame construction, each of which fails differently under water, frost, and load.
How we help in Nashua
The evaluations Nashua cases usually call for
- Foundation, frost, and snow-load evaluation
Cracked walls, heaved slabs, and sagging roofs in this climate can come from deep frost, flood saturation, snow and ice load, or a construction defect. Our licensed engineers evaluate the structure together with the soil and frost behavior and document which cause is responsible rather than assuming settlement.
Our structural engineering in Nashua- Flood and water loss investigation
After a river flood, ice dam, or roof leak, we determine what the water reached and whether the damage traces to the flood, wind-driven moisture, or a pre-existing condition. We ground each conclusion in the physical evidence at the property, not appearance alone.

Fire origin & cause
Fire origin and cause in Nashua
Nashua's converted mill and mixed-use buildings, with their concealed spaces and aged wiring, sit alongside 19th-century wood-frame housing that runs a long heating season on furnaces, wood, and supplemental heat. Those older systems and hidden cavities drive many of the fires we investigate, and old brick-and-timber construction burns and collapses in ways that can destroy the evidence fast.
Our NAFI-certified investigators work to NFPA 921: a systematic scene examination, burn patterns traced back to the area of origin, and evaluation of the electrical and mechanical systems, carried to a determination of accidental or incendiary cause. We preserve the evidence early, document the finding in a written report, and testify to it at deposition and trial.
Fires we investigate
- Residential and commercial fires
- Mill and mixed-use building fires
- Heating-system and wood-heat fires
- Electrical and appliance fires
- Vehicle fires
Common questions
Forensic engineering in Nashua, New Hampshire
A different question about your case? An engineer, not a call center, answers within 24 hours.
Was the 1936 flood really Nashua's worst?
Yes. The Northeast River Forecast Center records the March 1936 flood as the worst on the Nashua River, raising it about 12 feet and damaging the mills. The city now relies on a Merrimack levee and hydro dams, but river flooding remains part of the local record.
Can you tell frost heave from ordinary settlement?
Often. Deep seasonal frost lifts and drops footings differently than long-term settlement or flood saturation. We evaluate the movement pattern, the soil, and the drainage together before assigning a cause rather than assuming one.
Do you charge travel to reach Nashua?
No. We work Nashua-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?
