What we investigate in Manchester
Manchester's losses gather where the Merrimack meets a hard New England winter and the old Amoskeag mills: river flooding, freeze-thaw and ice load, and aging brick-and-timber construction. We investigate what actually failed and document it to a standard that holds, and a licensed engineer responds within 24 hours with no travel charges.
The conditions we see in Manchester
The Merrimack River is the dominant water hazard. In the May 2006 Mother's Day Flood the river ran roughly 10 feet above flood stage at Manchester, flooding homes along the valley, and an April 2007 nor'easter dropped up to 7 inches of rain and drew a Presidential Disaster Declaration for Hillsborough County. FEMA National Risk Index data flags a meaningful share of city buildings at elevated flood risk. Manchester also sits in a cold IECC climate zone, so deep frost, freeze-thaw cycling, and nor'easter snow and ice load all bear on foundations and roofs across a long winter.
The stock is defined by the Amoskeag Millyard, red brick textile mills built between 1838 and 1915 along more than a mile of the Merrimack, once the largest cotton plant in the world and now converted to offices, apartments, restaurants, and studios. Around them sit dense 19th and early 20th century brick and wood-frame rowhouses, triple-deckers, and worker housing, plus later mid-century and modern work. Heavy timber and brick mill framing, aged wiring, and old heating systems shape both structural performance under snow and ice load and the way these buildings burn. New Hampshire's granitic bedrock also carries elevated radon potential across the region.
How we help in Manchester
The evaluations Manchester cases usually call for
- Foundation, frost, and snow-load evaluation
Cracked walls, heaved slabs, and sagging framing in this climate can trace to deep frost, freeze-thaw, flood saturation, or ice and snow overload on an aging roof. Our licensed engineers evaluate the structure and the frost and soil behavior together and document which one is responsible, to a standard that holds up in a claim or in court.
Our structural engineering services- Flood and water loss investigation
After a Merrimack flood or an ice-storm event, we determine what the water did to the structure and whether the damage traces to the flood, a pre-existing condition, or a construction defect. We also investigate the component and construction failures that surface in older mill and housing stock, grounded in the physical evidence.

Fire origin & cause
Fire origin and cause in Manchester
Manchester's older mill and housing stock drives much of its fire loss. Heavy timber, open-floor mill buildings now carved into apartments and offices support rapid spread and structural collapse, and the Amoskeag mills carry a fire history going back to the 19th century. Aging wiring and old heating systems in 19th and early 20th century construction remain common ignition sources, and in that kind of building the cause is rarely obvious in the debris.
Our NAFI-certified investigators work these scenes to NFPA 921. They examine the scene systematically, trace the burn and char patterns back to the area of origin, evaluate the electrical, heating, and mechanical systems, and rule out causes until the evidence supports one conclusion, accidental or incendiary. Reaching a collapse-prone mill scene early preserves evidence that overhaul and weather destroy, and the same investigator documents the finding and testifies to it at deposition and trial.
Fires we investigate

Common questions
Forensic engineering in Manchester, New Hampshire
A different question about your case? An engineer, not a call center, answers within 24 hours.
Is foundation movement in Manchester from frost or something else?
It can be either. Deep frost and freeze-thaw cycling move footings here, but flood saturation, drainage, and construction defects produce similar cracking and heaving. We evaluate the pattern and the conditions to determine the cause rather than assume it.
Can you investigate a fire in a converted mill building?
Yes. Heavy-timber, open-floor mill construction spreads fire and collapses differently than modern buildings, and aged wiring and heating systems are common origins. We work the scene under NFPA 921 to trace the origin and determine whether the fire was accidental or set.
Do you charge travel to reach Manchester?
No. We work Manchester-area cases from our Omaha lab and Los Angeles office with no travel charges, and a licensed engineer responds within 24 hours.
