Drywall damage is one of the most common home repair issues I encounter when visiting homes across Shakopee, Burnsville, and the surrounding Twin Cities suburbs. A doorknob through a wall, a nail hole that grew into a gaping hole during a furniture move, a crack along a seam - these things happen in lived-in homes, and they're eyesores that most homeowners want fixed.
The good news is that some drywall repairs genuinely are good DIY projects. The less good news is that drywall finishing - getting the repair to blend invisibly with the surrounding wall - is genuinely one of the harder DIY skills to develop. More drywall repairs have been made noticeably worse by well-intentioned homeowners than almost any other home repair category.
Here's my honest breakdown of when to tackle it yourself and when to call for help.
What DIY Drywall Repair Actually Requires
Before diving into specifics, it's worth being honest about what drywall finishing requires: multiple thin coats of joint compound, appropriate drying time between coats, sanding between coats, and feathering the edges out far enough that the transition is invisible. The actual patching part is relatively straightforward. The finishing - the part that determines whether you can see the repair - takes practice to do well.
The tools you'll need for even basic repairs:
- Pre-mixed all-purpose joint compound (or setting-type for larger repairs)
- 4-inch and 6-inch putty knives
- 10-inch or 12-inch finishing knife for larger patches
- Sanding sponge and sandpaper (120-grit and 220-grit)
- Primer
- Paint (preferably the exact matching paint from your wall - save your paint codes)
The paint matching issue is often the hardest part of DIY drywall repair. Even if the patch itself is invisible, if the paint doesn't match - either in color or in sheen - the repair will still be visible. When in doubt, plan to repaint the entire wall rather than spot-painting.
Repairs That Are Genuinely Good DIY Projects
Small Nail and Screw Holes
Holes from picture-hanging nails - typically 1/8 inch or smaller - are the ideal DIY repair. You need spackling paste or lightweight joint compound, a putty knife, and about 20 minutes including dry time. Apply a small amount, let it dry, sand smooth, and touch up the paint.
Honest caveat: Even this "simple" repair will be visible if your wall has a texture and you don't match it, or if your paint is more than a year or two old and has faded. For a truly invisible repair, you may need to repaint the whole wall section.
Dents and Dings
Small dents without paper face damage - the kind that happen when furniture bumps a wall - can be filled with joint compound, sanded smooth, and painted. These are good DIY repairs.
Hairline Cracks at Corners and Seams
Hairline cracks along corner beads or at drywall seams are common in Minnesota homes due to seasonal movement. These can typically be filled with joint compound, feathered out, and painted. However, if the crack is in the same place year after year, it may indicate movement in the structure that should be evaluated rather than simply patched repeatedly.
Repairs That Require Skill and Experience
Medium-Sized Holes (3–6 inches)
A hole from a doorknob strike, a wall anchor that pulled out badly, or a small accidental impact - these are technically DIY-able, but this is where most homeowners get in trouble. The repair requires either a mesh patch or a "California patch" (cutting a clean square hole and using a backer board), multiple coats of compound over a larger area, good feathering technique, and matching the wall texture.
If your walls have any texture other than completely smooth (orange peel, knockdown, skip-trowel), you'll also need to match that texture with a spray texture or hand technique. This is genuinely hard to do well the first time.
If you want to try this yourself, watch several videos first, buy extra joint compound (you'll use more than you think), and plan for 3–4 days of work including drying time. And be prepared that it may not be invisible.
Larger Holes (6 inches and above)
Anything larger than about 6 inches requires cutting back to the studs, adding backing or blocking, installing a new piece of drywall, taping the seams, and finishing - essentially the same process as hanging new drywall. This is where I'd strongly recommend a professional.
The challenge isn't the patch itself - it's getting the texture and finish to blend. An experienced drywall finisher can make a large repair disappear. An inexperienced one often cannot, no matter how much time and effort they put in.
Water-Damaged Drywall
If your drywall has been wet - from a roof leak, a plumbing issue, or flooding - do not simply patch the surface damage. Before any repair work begins, the source of moisture must be addressed and the area must be fully dried out. Drywall that looks dry on the surface can hide moisture in the framing behind it.
Water-damaged drywall often needs to be cut out and replaced, not patched. And any drywall with visible mold should be handled carefully - affected material needs to be removed and disposed of properly, and the framing behind it evaluated.
If you have water damage, call a contractor or at minimum get an assessment before starting any repair work.
Cracks That Keep Coming Back
Cracks that reappear after being repaired are telling you something. Most often it's normal seasonal movement of the structure - this is very common in Minnesota homes, where the heating season brings dramatic humidity changes. But it can also indicate settling, foundation movement, or other structural issues.
A crack that has reappeared three or more times after repair warrants a professional evaluation, not another coat of joint compound.
Full Wall or Room Prep for Painting
If you're having a room repainted and there are multiple areas of damage, popped nails, nail holes, and dings throughout - this is typically more efficient as a professional job. A skilled drywall finisher will move through a room systematically in far less time than a homeowner tackling each repair individually.
The Texture Problem
I want to spend a moment on texture because it's the single biggest factor in whether a DIY drywall repair is visible.
Smooth walls are the most forgiving for DIY repair - there's no texture to match.
Orange peel texture (a fine, slightly bumpy texture that looks like the surface of an orange peel) can be approximated with spray texture cans, but matching the coarseness of existing texture takes practice. It's often better to sand the area around the patch smooth, apply the compound, and use a light orange peel spray over the whole area that will be repainted.
Knockdown texture (irregular flat areas separated by slight ridges) is produced by troweling joint compound and then lightly knocking down the peaks - this is a real skill that takes time to develop.
Skip-trowel and Santa Fe textures are similar to knockdown, and require practice with a drywall knife or trowel.
Popcorn ceilings - the textured ceilings common in homes built from the 1950s through the 1990s - are their own category. Matching existing popcorn ceiling texture is very difficult, and popcorn texture applied before approximately 1978 may contain asbestos and should be tested before any disturbance.
When to Call Hasselquist Contracting
I'm not going to tell you that you should never DIY a drywall repair - some of them genuinely are good weekend projects. But here's when I'd recommend picking up the phone:
- Holes larger than 4–6 inches
- Multiple repairs throughout a room
- Water damage of any kind
- Cracks that keep coming back
- Any texture that needs to be matched
- Repairs in highly visible locations (main living areas, entryways)
- Any time the existing paint color is unknown or unavailable
