Having large holes in your wall isn’t good.
Water leaks, kids playing, clumsy husbands…
They create drywall disasters.
This past weekend I needed to install a pedestal sink.
To do that I had to add wood blocking to the stud bay in the bathroom.
My wall had a gaping hole in it when I was done.
In a few hours I got the wall looking better than new.
I’ll show you how I did it in today’s tutorial 😀
I’m gonna share a ton of great tips.

There are a lot of supplies but you will use them again. Even if you’re fixing smalls holes.
Let’s jump into the first part, figuring out how to get a perfectly cut piece of new drywall for your hole.
How to prep your drywall hole
In this tutorial I had to add blocking for a pedestal sink.
If your hole is in the middle of the stud bay it’s a good idea to do one of two things
- either cut back the drywall to the next stud location
- or add wood blocking to the old drywall
Adding wood blocking allows you to secure the new drywall. Any 1 x 3 wood will work.
After you do that, measure the hole. Find the largest dimensions for the width and height.
Cut a new piece of drywall that covers those dimensions.
Place that piece of new drywall over the hole and trace it’s outline on the wall with a pencil
Cut along the outline with a drywall saw.
I personally like to cut along the outside of the pencil mark to create a slightly bigger opening for the new drywall.
Score the drywall with a utility knife where it butts against studs, you’ll be able to snap it off if it’s not glued to the stud!!
Thank goodness my drywall wasn’t glued, that can be pain in the @$$.
Make sure all nails and screws are removed from studs.
Mark the stud locations on the old drywall.
And if you have any pipes in the wall or wiring, mark a HUGE X on the wall to note their location.
You don’t want to accidentally drill a screw into a pipe or wire, that’s a bad surprise waiting to happen.
In the video I give you a good tip if you’re working in a bathroom.
Place tape over any shutoff valves if the supply lines are missing.
This prevents drywall dust from getting into the shutoffs.
Dust in shutoffs will transfer to your faucet and possibly cause it to clog, NOT GOOD!
Now it’s time to install the new piece of drywall.
And boy do I have some great tips for you.
Adding new drywall (tips out the wazoo)
Wazoo is a great word.
I looked it up on the urban dictionary. Funny stuff to say the least.
Two things I didn’t mention in the video
- if you have wood studs use coarse threaded screws
- if you have steel studs use fine threaded screws
Just a quick tip 😀
I like screws to be 8 inches apart.
Place the new drywall piece in the hole and secure it using a dimpler/drywall screw setter.
Dimplers help set drywall screw the correct depth.
And it’ll help prevent you from tearing the drywall paper, which is a no no.
Here’s the deal, you can use pre-mixed joint compound or setting-type joint compound.
The benefits of pre-mixed joint compound are it’s totally smooth (no chance for lumps) and gives you a great finish.
But it can take a long time to dry.
Setting-type joint compound has to be mixed and this creates a chance for lumpiness and a bad mud job.
That said, if you mix it correctly then you can fix a wall in one day because it will dry quickly.
I like using setting-type joint compound 20 or 45 because it dries in 20 or 45 minutes.
Drying times depend on temperature and humidity though.
Watch my video for all the details on how to mix the joint compound and apply it.
There are way too many details for me to describe in a written post and I don’t want you to fall asleep while reading.
Videos are way better for this kind of project 😀
Lots of money can be saved by doing your own drywall work.
