Structural Fire Damage Repair
Structural Fire Damage Repair and Reconstruction in Portland, OR
Following a fire, the structure often sustains severe damage that compromises the load-bearing capacity of walls, ceilings, and roof systems. Fire structural damage can range from charred exterior siding and melted roof trusses to fully collapsed interior walls. Identifying and correctly repairing these compromised elements requires expert assessment from licensed structural engineers and construction professionals to ensure the repaired building meets all current safety codes and load requirements.
Our Fire Structural Repair service handles all aspects of the building’s physical reconstruction after the initial cleanup and drying are complete. We manage the entire rebuild process, including necessary shoring, replacement of charred wood framing, subfloor repair, and installation of new roof systems. We work closely with the City of Portland permitting department and structural engineers to guarantee that every repaired beam, joist, and truss restores the full safety and integrity of your property.

Our 3-Step Fire Structural Repair Process
Engineering Assessment and Load Path Shoring
A licensed structural engineer assesses the damage to load-bearing elements. We install temporary shoring and supports to safely hold the structure while the damaged framing (joists, headers, trusses) is strategically removed and prepared for replacement.
Structural Rebuild and Code Compliance
We rebuild or reinforce all compromised structural components using new, code-compliant materials. This includes sistering charred joists, replacing roof trusses, and reframing damaged walls according to the engineering specifications and current Portland building codes.
Exterior Shell Repair and System Rough-Ins
We complete the building envelope reconstruction (new roof decking, exterior sheathing, weather barriers). We also manage the rough-in installation of mechanical, electrical, and plumbing systems, preparing the structure for the final interior finishes.
Q&A
How do you determine if a wood beam or joist needs to be replaced entirely or can be repaired?
The decision is made by the structural engineer based on the depth of charring. If the charring is minor (surface level), the beam can often be structurally repaired by sistering a new piece of lumber alongside it. If the charring has penetrated deep into the wood and significantly reduced the cross-section of the wood member, it must be replaced entirely to ensure the proper load-bearing capacity is restored.
What is "sistering" in fire structural repair?
Sistering is a technique used to repair moderately damaged framing. It involves securely fastening a new, identical piece of lumber alongside the existing, damaged beam or joist. When bolted or nailed together properly, the two pieces act as a single, structurally sound unit, restoring the necessary load capacity without the complex demolition required for a full replacement.
Will the structural repair work be inspected by the city or county building department?
Yes, absolutely. Any repair that affects the primary structural or load-bearing components of the building requires a permit and mandatory inspections by the City of Portland or county building official. We handle the entire permitting process and ensure all repairs are performed according to the approved engineering plans and are signed off on by the local authority.
Does fire damage compromise the concrete foundation, and do you repair that?
While concrete is non-combustible, intense heat can cause surface spalling (flaking) or cracking. In extreme cases, extended exposure to high heat can compromise the structural integrity of the concrete. We work with specialized concrete contractors to assess and repair foundation or slab damage, including crack injection or replacement of severely affected sections, ensuring the base of your property is sound.
Can I upgrade the energy efficiency of my walls during the structural repair process?
Yes, this is an excellent opportunity for energy upgrades. As the walls are open during the repair of the framing and before the new drywall is installed, we can install modern, high-efficiency insulation (e.g., closed-cell spray foam or high-density batts) that greatly exceeds the original insulation and improves the long-term energy performance of your rebuilt Portland property.
