What you can fix yourself and what costs money
Most wall damage falls into three categories: small holes (nail holes, picture hangers), dents and dings (furniture bumps, door handles), and marks (scuffs, crayon, tape residue). You can patch small holes and dents yourself for under $20 using materials from any hardware store. Marks often come off with a magic eraser or the right cleaner, which costs almost nothing. Larger holes — anything bigger than a quarter — usually need joint compound and sandpaper, still cheap but requiring more time and a steadier hand.
The decision to fix it yourself or hire someone depends on the size of the damage and whether you rent or own. Renters often need to repair damage before moving out to recover a security deposit, which makes the DIY route worth learning. Owners can choose based on time and confidence. Most wall repairs that don't involve structural damage or water stains are within reach of someone doing it for the first time.
Key Takeaways
- Nail holes and small dents can be filled with spackling compound for $3 to $8 per container, which covers dozens of repairs.
- Magic erasers and rubbing alcohol remove most marks and scuffs without damaging paint, costing $1 to $5 per item.
- Holes larger than a quarter need joint compound (drywall mud), sandpaper, and a putty knife — a full kit costs $15 to $25.
- Paint touch-ups require matching your wall color, which you can do by bringing a paint chip to the store or finding your original paint can.
- Renting tenants should photograph damage before repair and keep receipts, since some landlords reimburse repair costs from the security deposit.
Filling nail holes and small dents
Spackling compound is the standard tool for holes smaller than a quarter inch. It comes in white or paintable tubes and containers, dries quickly (usually 1 to 3 hours), and shrinks slightly as it dries, so you overfill slightly and sand smooth. A $5 container fills 20 to 30 small holes. You need a putty knife (a flat blade 2 to 3 inches wide), which costs $3 to $8 new but you may already have one in a junk drawer.
The process is straightforward: apply spackling with the putty knife, overfill the hole slightly, let it dry, then sand with fine-grit sandpaper (220-grit or higher). Wipe away dust with a damp cloth and paint over it. For nail holes, you can often skip the sanding step if you apply it flush with the wall. Dents need more spackling because they're wider but shallower — apply in thin layers rather than one thick coat, which cracks as it dries.
If you rent, check your lease about repair costs. Some landlords deduct repair expenses from your security deposit; others expect you to leave walls in move-in condition. Taking a photo of the damage before you repair it protects you if there's a dispute about whether the damage was pre-existing.
Removing marks, scuffs, and stains
A magic eraser removes most marks without chemicals or scrubbing hard enough to damage paint. They cost $1 to $3 for a pack of four and work on crayon, pen, marker, scuffs from shoes or furniture, and most dirt. Wet it slightly, rub gently in circular motions, and wipe the residue with a clean cloth. Test on an inconspicuous spot first — magic erasers can dull matte or flat paint if you scrub too hard.
For marks that don't respond to a magic eraser, try rubbing alcohol on a cloth (not sprayed directly on the wall, which can damage drywall). This removes pen, marker, and some adhesive residue. Hairspray also works on some pen marks. For tape residue, peel off what you can, then use a cloth with rubbing alcohol or a commercial adhesive remover like Goo Gone ($3 to $5). Always test on a hidden area first — some removers can strip paint.
Water stains and mold require different treatment. Water stains may disappear once the wall dries completely, but if they return, the leak is still active and needs fixing before you paint over it. Mold (black or green spots) should not be painted over — it grows under paint. Clean it with a bleach solution (1 part bleach to 10 parts water) and address the moisture source, or call a professional if you can't locate it.
Patching holes larger than a quarter inch
Holes bigger than a quarter need joint compound (also called drywall mud or spackle), which is thinner and stronger than spackling compound. It comes premixed in buckets ($5 to $10) or as a powder you mix with water ($3 to $6). Premixed is easier for beginners. You'll also need a putty knife (4 to 6 inches wide for larger holes), fine-grit sandpaper (220-grit), and a damp sponge or cloth for cleanup.
For a hole up to 2 inches across, apply joint compound in one or two coats. Spread it with the putty knife, feathering the edges so it blends into the wall. Let it dry (usually 2 to 4 hours for premixed compound), then sand smooth. If the hole is deeper than half an inch, apply a thin first coat, let it dry, then apply a second coat. This prevents cracking. For holes larger than 2 inches, you may need a backing patch (a small piece of drywall or mesh) glued behind the hole first, which adds complexity and cost.
After the compound dries and you've sanded, wipe away dust with a damp cloth and let it dry completely before painting. Paint won't stick well to dust, and you'll see the repair through the paint if you skip this step.
Matching and applying paint
Paint color matching is the most common mistake in wall repairs. A patch that's the wrong shade stands out more than the original damage. If you have the original paint can, bring it to the store and ask them to mix a small sample (usually free or $2 to $3). If you don't have the can, take a paint chip from an inconspicuous spot (inside a closet, behind a door) to the paint counter and they'll scan it and mix a match.
Buy the smallest size available — usually a quart ($8 to $15) — unless you're patching a large area. Use a small brush or foam applicator ($1 to $3) to paint over the repair. Apply thin coats rather than one thick coat, which shows brush marks and takes longer to dry. Two thin coats usually cover better than one thick one. Let each coat dry before applying the next (check the can for drying time, usually 1 to 4 hours).
If the wall has a texture (popcorn, orange peel, knockdown), matching becomes harder. You can buy spray-on texture ($5 to $10 per can) to match common patterns, but it requires practice. For textured walls, consider whether the repair is visible enough to matter — sometimes a smooth patch on a textured wall is less noticeable than you think, especially if it's in a corner or behind furniture.
When to call a professional
Hire a professional if the hole is larger than 6 inches, if there's water damage or mold, if the wall is textured and you can't match it, or if the damage is near electrical outlets or switches (which require care around wiring). A handyperson or drywall contractor typically charges $100 to $300 for a single repair visit, depending on location and damage size. For renters, this cost often comes out of the security deposit, so weigh it against the deposit amount.
If you're uncertain whether you can do it yourself, ask the hardware store staff — they see people attempt repairs all the time and can tell you honestly whether it's worth trying. Many will also show you the technique in the aisle. Some stores offer free how-to videos online or in-store workshops, which can build confidence before you start.

Frequently Asked Questions
Can I paint over spackling compound without sanding?
You can, but the repair may show through the paint. Sanding creates a smooth surface that paint adheres to evenly. If you skip sanding, use a primer first — it helps hide the spackling and gives paint something to grip. Primer costs $8 to $12 per quart.
What's the difference between spackling compound and joint compound?
Spackling compound is thicker, dries faster, and shrinks more as it dries — it's for small holes. Joint compound is thinner, takes longer to dry, and shrinks less — it's for larger repairs and creates smoother edges. For holes under a quarter inch, spackling is easier. For anything bigger, joint compound works better.
How do I match textured walls?
Bring a photo or a small sample of the texture to the paint store and ask what spray-on texture matches it. Common patterns are popcorn, orange peel, and knockdown. Practice on cardboard first — texture sprays are hard to control. If you can't match it well, a smooth patch may be less noticeable than a mismatched texture, especially if it's in a corner.
Will my landlord charge me for wall repairs when I move out?
That depends on your lease and local tenant laws. Normal wear and tear (faded paint, small nail holes) is usually the landlord's responsibility. Damage beyond normal wear (large holes, deep dents, permanent stains) can be deducted from your security deposit. Document the condition with photos when you move in and when you move out, and keep receipts if you repair damage yourself.
Can I use caulk instead of spackling for wall holes?
Caulk is designed for gaps between materials (baseboards, trim) and doesn't sand smoothly like spackling does. It also shrinks differently and may crack. For wall holes, spackling or joint compound works much better and looks cleaner after painting.
