Okay! I went to the local hardware store (support your local hardware store) and got that foam filler as well as white silicone glop. I cut all the foam to fill in all the gaps. Look at that love, that care.
Then I cleaned off the housing and good Lordt, the grime. Look at these swiffers.
Now, because removing the caulk ripped off a lot of layers of wall, I took small bits of paper and put it back with glue so I’ll have a relatively flat surface to spackle on. Remember, we’re not going for flawless, we’re going for not so wretched that it catches your eye.
Next I do a little spackle-y spackle-y, and little sand-y sand-y, a little paint-y paint-y and then the silicone glop. We should be good then.
