How to Re-caulk Cracked Stair Stringer Seams
Hey guys, just sharing a quick little tip on how to re-caulk cracked stair stringer seams. Although we hired out the job of refinishing our carpeted stairs to wood treads, I took on the job or re-caulking the stair stringers and trim. The caulk was cracking, and I couldn’t have that next to my beautiful new staircase!
This topic also lines up nicely with this month’s DIY at Home theme of home improvement. After you check this project out, definitely check out the other projects at the end of the post!
Here’s what I used:

- Utility knife
- Paintable caulk
- Caulk gun
- Disposable gloves
- Cup with water
- Paper towels
- Paint to match existing white
And here’s how to re-caulk cracked stair stringer seams.
Step 1: A lazy way would be to just run a bead of caulk over the existing cracked caulk. Although I do some things the lazy way, this was not one of them. I wanted the new caulk to last, so I removed all of the old caulk first.
I did that using a utility knife to slice down the middle of the caulk seam and then used the pliers to pull out a starting point. Most of the caulk came out pretty easily, which was a nice surprise. I expected to be picking bits out for a while.
Step 2: Once the existing caulk was gone, I applied FrogTape to create the outline of where I wanted to caulk. This was honestly the most time-consuming part of the process. But I’m not a professional caulker, so I always feel like I need the training wheels to get a perfect line.
Step 3: I began applying the caulk at the top of the stairs on one side and stopped about halfway down. Then I went back to the top, dipped a gloved finger in a bit of water, and ran it along the bead of caulk to press it in to the seam and smooth it out. Just a bit of water helps here. I wiped excess caulk on to a paper towel.
Step 4: I removed the tape from the caulked area immediately (and carefully) and repeated steps 3 and 4 until all areas were caulked. I also caulked the area between the trim and the wall and then the area between the treads/risers and the stringers using the same method. (Lots. of. tape.)
After everything was sufficiently dry, I gave the stringers and trim a coat of white paint to match the existing color, and they look brand new! And there ya go.
