NSP Joist Repair Kits

Joist Repair Solutions

Engineered repairs for cut, notched, or damaged floor joists

Floor joists are frequently compromised during renovations, plumbing or electrical upgrades, or decades of service in older homes. These conditions are often discovered during inspections or remodels—long after the damage has already occurred—and can result in bouncy floors, sagging, or failed inspections.

Our joist repair solutions are engineered to permanently restore the structural strength of damaged floor joists without requiring full joist replacement or demolition.

Why Engineered Joist Repair Is Needed

Notched, drilled, or damaged joists can no longer perform as originally designed. Traditional repairs often require removing plumbing, electrical, or HVAC lines—or rebuilding large sections of framing—which can be invasive and costly.

The products in this collection provide a code-compliant structural repair that reinforces the joist while allowing existing plumbing, electrical, and HVAC lines to remain in place.

What These Products Are Designed to Do

  • Repair cut, notched, drilled, or otherwise weakened floor joists
  • Restore the structural capacity of the joist
  • Provide a permanent solution, not a temporary patch
  • Allow existing utilities to remain undisturbed
  • Address real-world conditions commonly found in older homes

All joist repair solutions in this collection are engineer-designed and intended for permanent structural repair when installed as specified.

Code-Compliant, Permanent Repairs

Joist repair products in this collection have been accepted by code enforcement officials and are used in residential structural repairs across the United States and Canada. When properly selected and installed, they provide a permanent repair that fully restores joist strength.

If you are unsure which product is appropriate for your situation, our team can help review measurements and conditions to guide you toward the correct solution.
