How to Repair Joists and Rafters

Would you like to know how to repair joists and rafters without tearing out the walls, floors, or ceilings? There are a number of helpful hints to making this DIY project go smoothly.

Most of these types of repairs do require the aforementioned demolition. If you have a timber-resin splice system, then you can do this easier and without all the hassle. With this system, you can cut out an end section that needs to be repaired and then add in the new section. These kits come in many shapes and sizes, so it would be easy to find the size you need to replace the rotted section. One of the advantages of this type of repair is that it will make the rafter or joint repair stronger than the original.

You can access your joist by removing a floor board. It is easier to access a rafter from underneath, if possible. Find the area that needs repaired. Cut that section out. Drill a slot in the remaining section that is big enough for the steel rods that are protruding from the new block in your kit. Attach the new block and push it into wall. Place the steel rods into the slot that you cut previously. Then, pour in the resin that came with your kit. This is for an end repair rather than a mid-span repair.

If you need a mid-span repair, there is a timber-resin splice system for this as well. If you decide to go with the aforementioned kit, be sure you know which type you will need for this project.
