How To Replace Framing Plates


Step #1. Preparing for the replacement

Replacing a load-bearing framing plate is a difficult task as the house’s structural integrity depends on it. If it collapses, the house might also collapse. In cases such as this, asking for a professional’s help is highly recommended.

Nevertheless, you can do all the work yourself, provided you have the right tools and the know-how to accomplish the task. First and foremost, you should talk to concerned government agencies and get a permit for the construction. Once a permit is secured, you can proceed with the repair.

It would be best to find the reason for the water damage. Is it because of a leaking pipe or because of a damaged bathtub or toilet? You should repair the cause of the water damage first before you fix the wall itself.

It would help if you asked your insurance provider or consulted your lawyer about your insurance coverage. Some insurance policies cover water damage from leaking pipes and other accidental water damage. In doing so, you might be able to get money to aid in your repairs.


Step #2. Remove the toilet

Since the framing wall is behind the toilet, you will need to get the toilet out of the way. To remove a toilet, you must first turn off the water supply. Afterward, you should remove all the water by flushing the toilet bowl until the water stops draining.

Remove the remaining water using a sponge and a bucket. Once all the water is drained, you can remove the bolts that attach the toilet to the floor. Then, cut through the layer of caulk around the toilet using a utility knife and then pull it straight up and off the bolts.

Place the toilet bowl somewhere that it would not hinder your movements. Before moving to the next step, you should clean up the dirt and debris that came from removing the toilet.


Step #3. Shore up the wall

Since the framing plate bears the weight of the house, you should shore the wall first before you remove anything. You can shore up a wall by placing a temporary row of angled 2x4s alongside the existing wall.

Screw two 2x4s to the ceiling and the floor, directly on top of one another. Afterward, wedge pieces of 2×4 between the plates and nail them into place. If you have a basement, you should put the shore directly underneath the wall you are working on.


Step #4. Cut away the damaged area

Now that the wall is shored, you can start working on the water-damaged wall. The sill plate is probably the most damaged part of the entire frame since it is at the bottom.

First, cut the power off for the entire house to reduce the risks of electrocution. Afterward, expose as many of the frames as possible by cutting through the drywall. Assess the extent of the damages.

If you believe that the damage is too extensive to work on alone, consider hiring contractors to do the job. If the damage is minimal, you can proceed to the replacement process.

Remove the affected parts of the frame. You will most likely need to remove the sill plate and a few floor joists. You will need to cut the frames and the nails that attach them to the other parts of the wall.


Step #5. Replace the damaged frame

Once all the affected parts are removed completely, all that is left to do now is to replace the damaged frame. In this step, it is best to remember that you must replace everything that you removed.

If you removed the sill plate, you should replace it preferably with treated wood to ensure longevity. Install the new studs using glue and nails. Install joist hangers to each end of the room and place 2×12 joists to lock the entire floor solidly.


Step #6. Put everything back to their place

Now that you have secured the frame, all that is left is to put everything back together. Replace the wall if you made a big incision or simply patch it up if the cut is small.

Reinstall the toilet. Turn the water supply and the electricity back on and clean the area up.



Knowing how to replace water damaged framing plate behind toilet will aid in keeping your home structurally safe and remove all the risks of growing mold and mildew. By following a simple 6-step process, you can replace water damaged framing plates like a professional. However, it is important to remember that if the task is too big, you should consider enlisting the help of professionals.
