We’ve all been there: You walk into your living room in a good when you notice a tiny crack snaking its way across the drywall. It's like a little blemish that suddenly breaks the spell of your otherwise perfect space.
While drywall is a great cost-effective option for finishing your walls, those cracks have a way of making even the most well-kept rooms look a little neglected. But don’t worry; drywall repair isn’t as daunting as it might seem. With the right tools and some patience, you can even patch up those cracks yourself.
In this brief article brought to you by Mr. Handyman, we walk through what it takes to repair drywall cracks in your home. If you’d rather have a trained and uniformed handyman take care of it, then call Mr. Handyman to get in touch.

Assessing the Crack: Is It a Small Job or a Bigger Problem?

Before you grab your spackle and get started, we have to figure out how big of a repair job you’re dealing with. In many cases, those hairline fractures are no big deal. They might just be caused by the house settling or a slight shift in temperature and humidity. These types of cracks are typically surface-level and won’t require much effort to fix.
But if you’re dealing with a wider crack – especially one that runs across the ceiling or the length of a wall – then you may want to dig a little deeper. A wider crack could indicate structural movement or water damage, and it might be worth calling in a professional to assess the situation before you proceed.

Gather Your Materials

You don’t need a ton of fancy tools to repair a drywall crack—just the basics. Here’s what you’ll need:

Joint compound
Drywall tape
Putty knife
Sanding block or sponge
Primer and paint

These supplies are all readily available at your local hardware store or home improvement center like Lowe’s or Home Depot.

Start by prepping the area around the crack. Clean the surface around the crack and use a utility knife to gently widen the crack if it’s very narrow (this allows the compound to fill the crack more effectively).
Next, use your putty knife to apply a thin layer of joint compound over the crack. Try to keep the layer thin and even to avoid excess sanding later. Once the crack is covered, feather the edges of the compound so that it blends with the surrounding wall.
Now, let it dry. Depending on the thickness of the compound and the humidity level, it could take anywhere from a few hours to overnight to fully dry.
Once the final layer of the compound is dry, it’s time to sand. Use a sanding block or a sanding sponge to smooth the area until it’s flush with the wall. Big cracks may require multiple layers. After each layer dries, lightly sand it with a fine-grit sanding block to smooth it out.
Finally, it’s time to make the repair disappear! Apply a coat of primer to the patched area. After the primer dries, paint over the repaired crack with a color that matches the rest of your wall. You may need a couple of coats for best blending.
