How to Fix a Hole in the Wall

Chicago walls collect damage with a backstory, like the doorknob that swung too hard or the TV mount holes a tenant left as a souvenir. How to fix a hole in the wall comes down to two facts you can check in five minutes, what the wall’s made of and how wide the damage is. Learning how to patch a hole in the wall yourself saves a service call, and we’ll survive that.

Drywall or Plaster? Check Your Wall First

CMAP’s Chicago snapshot from June 2026 puts 38.8% of the city’s homes before 1940, with a median build year of 1953. That’s a lot of 1920s walls still wearing plaster and lath under five coats of paint.

Start with a knock test. Drywall gives a hollow, slightly cheap sound, and plaster thuds back like a kitchen counter. A thumbtack slides into drywall with almost no push and stalls in plaster. Thin wood strips at the edge of the hole are lath, and lath means everything below this section was written for somebody else’s wall.

Match the Fix to the Size of the Hole

A tape measure across the widest point settles more than any video tutorial, since a nail hole and a doorknob crater share a wall and little else.

How to Fill Small Holes in the Wall

Nail and screw holes live here, plus the four craters a wall anchor leaves once the mount comes down. Learning how to fill holes in walls this small takes ten minutes of work and an hour of waiting.

Pull a plastic wall anchor out with pliers, and let a toggle bolt wing drop into the cavity for good.

Press lightweight spackling into the hole with a putty knife and scrape it flat in one pass. A second pass is how small holes become small bumps. Once it’s dry, a sanding sponge levels it and a dab of primer stops flashing, the dull spot that shows through eggshell finish.

How to fix small holes in drywall gets very relevant on moving day. If the TV’s going up again somewhere new, our TV mounting crew puts it into studs this time.

Spackle vs Joint Compound

The two tubs sit side by side at the hardware store, which is how people grab the wrong one. In the spackle vs joint compound debate, spackle takes anything smaller than a quarter and compound takes anything you mesh or tape.

How to Patch a Hole in Drywall Up to 4 Inches

A chair back or a missing door stop leaves this size, and it’s the job a self-adhesive drywall patch was made for. Friday night is fine for prep, which means a utility knife to shave the fuzzy paper off the edges and the mesh patch stuck dead center.

Coat one goes on with a 6-inch taping knife, so thin the mesh still shows through. Saturday’s coat runs a couple of inches wider, and that feathering is the whole trick of hiding an edge. By Sunday afternoon it’s a sanding sponge, a wipe of the dust, primer and touch-up paint.

Medium Holes, 5 to 12 Inches: The California Patch

Doorknob holes land right in this range, and the California patch drywall finishers use skips the backer board and the butterfly patch kit alike.

Once the drywall saw has squared up the damage, cut a scrap 2 inches bigger on every side and snap the gypsum off its back edges, and you’re holding a square plug in a paper skirt. Butter the edges of the doorknob hole and push the plug in until the paper lies flat in the mud, and two more coats over the next day finish it.

A door stop costs a few dollars, which beats a rematch with the same knob. Doors that drag or slam go to our door repair team.

How to Patch a Large Hole in Drywall

Past 12 inches you’re replacing a piece of wall. An electrical wire or a plumbing line loves to run exactly where you planned to cut, so the breaker goes off and a flashlight goes through the opening before the saw comes out. An outlet box a foot away gives a cable away, and a stud finder handles the framing.

Where the studs refuse to cooperate, a furring strip screwed inside the opening does their job, and the cut goes back to a rectangle that reaches framing on each side. How to fix a hole in drywall this big then works like the medium version with more screws, and paper tape or mesh tape goes over the seams before the compound.

Chicago’s Department of Buildings allows up to 1,000 square feet of drywall or plaster work without a permit, provided the plumbing and electrical stay put.

Before You Sand: Lead Paint and Old Compound in Chicago Homes

A 1925 two-flat probably has lead under the newer coats, since EPA counts about three in four US homes built before the 1978 ban as still carrying it. Dry sanding turns that paint into dust on the floor, at exactly the height a crawling kid breathes.

The Chicago Department of Public Health lead guidance treats those homes as likely lead homes and steers renovations to EPA-certified contractors. EPA’s rule skips owners doing their own work, though the dust doesn’t care.

EPA also lists old patching compounds and textured paint as places asbestos can hide. Run a lead test kit first and wet-sand. The OSHA overview of lead dust hazards explains why the fine dust is the dangerous part.

When to Call a Handyman

A ceiling hole means ladder work, and texture matching overhead is its own sport. Brown rings around the edge say water got there first, and water damaged drywall needs the leak fixed before any mud. Wiring or pipes behind the wall go on that list, along with a rental full of anchor holes and a Friday move-out. Our drywall repair in Chicago crew prices drywall hole repair by size.
