The Joist Repair Strap is designed to repair notched, drilled or damaged floor joists without needing to remove any plumbing/wiring which may go through the joist.  Our product provides an affordable, alternative solution to sistering the joist in order to restore the integrity of the joist and promote safety.  Each kit consists of a steel strap that is ideally screwed to the bottom of the floor joists.  If you don’t have access to the bottom of the joist, our product may still work.  Please contact us for more information.

The Joist Repair Kit is great for both homeowners, contractors, and DIYers as it includes everything needed to install. Once the strap is installed it will fully restore the strength of the floor joist. There is an engineered design report available by using the link above that can be provided to a Building Department, if required.  The Design Report is stamped by certified Engineers in multiple States and has been accepted by Building Inspectors across the United States and Canada. 

The lag screws included are 1/4" by 1, 1/2" and will protrude out about an 1/8" from the steel.

**Please Note: This product will not work for every floor joist.  Please contact us directly if you have any concerns if this product is the correct solution for you.**

Thank you !

Found off YouTube

I was researching ways to reinforce a joist with notches removed. I found a YouTube video describing this product. As a mechanical engineer myself, I really appreciated the mathematical explanation of how this strap reinforces the joist. Installation was easy and now there's a bathtub installed on what was once a weakened joist with no issues!

joist repair

i have a 17 foot 2x12 joist that failed due to a large knot. this was far easier than sistering the joist.

Harold Kirk

Works like a charm

Couldn't ask for better

Used the product to fix a joist and the bldg inspector was skeptical until I showed the video and the credentials of the engineer (designer). Saved me major bucks. Also appreciated that all tools needed were included and that it was shipped quickly. Usually I don't write reviews but this simple product was great.
