What moves that number most is usually one thing: Extent and Location of Damage.

Mid-Range
Moderate damage affecting several floor joists, subfloor sections, or wall framing, sistering damaged members, partial flooring replacement.
Premium
Extensive damage to structural members, sill plates, rim joists, and subfloor throughout a significant area, requiring engineer assessment and full framing replacement.
Material Options
Material prices below are national averages; availability in Boston may shift costs slightly.
| Material | Cost/Unit | Best For |
|---|---|---|
| Sistering Damaged Joists | $200-$600 per joist | Floor joists with localized damage that retain at least 50% of their structural sectionLess invasive than full replacement, maintains floor elevation, no need to remove subfloor above |
| Full Joist or Stud Replacement | $400-$900 per member | Members with severe damage, collapse risk, or widespread decay beyond sisteringComplete structural restoration, like-new performance, required for severely damaged members |
| Sill Plate Replacement | $200-$500 per linear ft | Sill plate damage - the highest-priority structural repair for termite-damaged homesRestores the critical connection between framing and foundation, uses pressure-treated lumber resistant to future infestation |
| Epoxy Wood Consolidant and Filler | $30-$100 per application | Window sills, door frames, exterior trim with minor to moderate damage where replacement is impracticalNon-invasive, fills voids in partially damaged wood, can restore structural integrity of minor damage, paintable |
| Pressure-Treated Lumber Replacement | $300-$800 per member | Sill plates, rim joists, and any framing within 6 inches of soil or concreteChemically treated to resist future termite damage, required in many jurisdictions for ground-contact applications |
