SERVICE GUIDE
Structural & joist repair.
Prepare for a structural assessment and compare a clear joist, beam or support repair scope.
Start with findings, then compare repairs.
A structural or joist repair quote should identify the affected framing or supports, the evidence behind the recommendation and who is responsible for the repair design. A low floor, visible crack or dark patch on wood does not tell you which repair to buy. Use this checklist when arranging an assessment and comparing proposals; our full structural repair guide explains the components and warning signs.
NC State Extension cautions that mold on joists or beams does not establish that wood decay will occur. Ask for separate findings about moisture, the wood itself and any suspected pest damage.
BEFORE THE VISIT
Give the inspector a useful starting record.
- Which room or location is affected, and when did you first notice the change?
- Did a leak, storm, previous repair or remodeling project precede it?
- What existing photos, inspection reports or repair drawings can you share?
- Which areas have not been inspected or cannot be reached safely?
Use the inspection checklist to organize that record. Do not enter an unsafe crawl space or adjust posts or jacks to gather evidence. If a floor or support appears to be failing, keep people away and seek urgent professional assessment; use emergency services for immediate danger.
Clarify who evaluates and designs the work.
Ask whether the visit provides a visual condition report, a contractor proposal or an engineering assessment, and what it excludes. EPA recommends a structural engineer or another professional with relevant expertise when mold is suspected of affecting structural integrity. For uncertain support conditions, conflicting diagnoses or substantial proposed framing changes, ask whether an independent structural assessment should come before the final quote. These are planning questions, not a diagnosis or a universal engineering requirement.
Put these details in the written scope.
- Locations and quantities: Identify each joist, beam, support or other area included, using marked photos or a drawing. Ask what remains concealed or excluded.
- Repair details: Name the person specifying the work and the drawings or written details the installer will follow. Ask why the proposed repair suits the observed condition.
- Work around the repair: Assign responsibility for professional temporary support, protection of utilities, access, debris removal and any finish restoration.
- Intended result: Ask whether the goal is stabilization, reduced movement or a specified floor-level change, and how completion will be checked. Do not assume every repair includes leveling.
- Local checks: Identify who confirms permit and inspection requirements with the building department for the property, and whether those tasks and costs are included.
- Newly exposed damage: Agree how additional findings, revised repair details and price changes will be documented for your approval.
Give bidders the same findings and record unresolved differences in the quote-comparison worksheet. A package name or a count of supports is not a complete scope.
Coordinate moisture work and project closeout.
PNNL’s pre-retrofit guidance calls for structurally sound framing and correction of moisture sources before further retrofit work. Ask the repair and moisture-control professionals to agree on the sequence, drying checks and inspection access before surfaces are covered.
At completion, request photographs before concealment, the final repair details, applicable inspection records and a walkthrough against the agreed scope. Keep unresolved areas, follow-up responsibilities and warranty exclusions in writing.
