Common Causes of Large Holes in Walls

There are numerous causes of large wall damage, including:

• Unintentional impacts: You may have issues with plasterboard. It can be punctured by slamming doors, tripping, or moving furniture.


• Electrical or plumbing work: To reach pipes or wiring, tradespeople frequently make incisions in walls.


• Moisture damage: Plasterboard can deteriorate until it crumbles due to leaks from pipes, roofs, or flooding.


• Children and animals: Unexpectedly large marks may result from roughhousing, toy throwing, or scratching.


• Wear and tear: It is possible that older homes already have weak areas that crack under pressure.

It is critical to identify the cause; if water damage is to blame, you must address the leak before repairing the wall.

Tools and Materials You Will Need

You may assemble the necessary equipment and materials before beginning your repair.

• Plasterboard repair (or a fresh plasterboard sheet)


• Utility knife or plasterboard saw


• A pencil and measuring tape


• Spirit level or straightedge


• Battens made of wood (for backing support)


• Screws and a drill or screwdriver


• Plaster filler or jointing compound


• Jointing tape (fibreglass mesh or paper)


• Sandpaper or a sanding block (medium and fine grit)


• Apply primer and topcoat paint to the wall as it is.


• Safety equipment (gloves, safety glasses, and a dust mask)

Optional: A pre-made plasterboard repair kit can be found in many hardware stores in New Zealand. It comes with the majority of the necessary parts.

Step-by-Step Guide to Fixing a Large Hole in the Wall

Here's a simple, doable method for patching big plasterboard holes. You can read this if you need a solution for the question, How to Fix a Large Hole in the Wall?

Step 1: Prepare the Area

• You should clear the hole of any debris or loose plaster.


• To create a clean, square, or rectangular hole, you can use a utility knife to widen the rough edges. Patching becomes simpler as a result.


• Before cutting, you can look for any concealed electrical wiring or pipes.

Step 2: Measure and Cut the Patch

• You should determine the hole's dimensions.


• You can cut a piece of plasterboard that is just a little bit bigger than the hole.


• After placing it over the hole and tracing around it, you should cut the wall to fit the patch's shape.


• Advice: Fitting a square or rectangular patch is simpler than attempting to match an irregular shape.

Step 3: Install Backing Support

• Large holes need support behind them to hold the patch in place.


• You can cut two battens of wood that are just a little bit longer than the hole.


• Part of each batten should remain visible inside the hole after they are inserted into the wall cavity and screwed into the surrounding plasterboard.


• These battens will be screwed to the patch.

Step 4: Fit the Plasterboard Patch

• Then, you can insert the piece of cut plasterboard into the hole.


• Securely screw it into the wooden battens.


• After that, you can make sure the patch and the original wall surface are flush.

Step 5: Apply Jointing Tape

• Then, wrap the patch's edges in paper or fibreglass mesh joint tape.


• This keeps the joints between the old and new plasterboard from cracking.

Step 6: Apply Jointing Compound

• You can apply a thin coating of jointing compound to the patch and tape using a plastering knife.


• To blend in with the surrounding wall, feather the edges.


• Then, let it dry completely (follow the drying times on the product label—often overnight).

Step 7: Sand and Repeat

• Lightly sand the dried compound until it's smooth.


• You can spread a second layer of jointing compound farther away from the repair.


• After drying, sand once more. For a seamless finish, a third coat might be required.

Step 8: Prime and Paint

• After the patch is smooth, you can seal it with a layer of primer.


• To match the rest of the wall, paint over the repaired area.


• The repair should be almost undetectable if done properly.

DIY vs Professional Repair in New Zealand

The following factors determine whether you should hire a professional or fix a big hole yourself:

DIY is suitable if:

• If the hole is less than 30 cm wide, DIY is appropriate.


• You feel comfortable using simple tools.


• You enjoy taking the time to paint, smooth, and sand.


• Plasterboard, not the structure, is damaged.

Call a professional if:

• If the hole is larger (more than 50 cm).


• Inside the wall, there is plumbing or electrical damage.


• Because of its texture, the wall needs specialised finishing.


• You want the hassle-free, faultless outcome.

Depending on the intricacy and level of finish needed, plasterers or handyman services in New Zealand typically charge between $100 and $300 NZD to fix a medium-sized wall hole.

Tips for a Seamless Finish

• For smooth edges, you can use wide plastering knives (150–300 mm).


• For optimal results, always sand in between joint compound coats.


• Carefully match paint colours by bringing a sample to any paint counter in your area.


• Do not hurry. Before sanding or reapplying, you can allow each coat to completely dry.

You can use these tips if you are worrying about how to fix a large hole in the wall.

Preventing Future Wall Damage

After you have patched the hole, it is worthwhile to take precautions against it recurring:

• Door stoppers: Installing door stoppers will stop doorknobs from making holes in the walls.


• Furniture pads: Cushion furniture's sharp corners.


• Supervise play areas: You should keep an eye on play areas and urge children to refrain from rough play close to brittle walls.


• Address moisture problems: To prevent plasterboard from deteriorating, you can fix leaks as soon as possible.

Eco-Friendly Disposal of Old Plasterboard in NZ

Be sure to properly dispose of any damaged plasterboard when removing it. In New Zealand:

• You can verify the policies of your local council; certain transfer stations take recycling plasterboard.


• Plasterboard recycling options may be available for larger quantities through services.


• Recycling can help reduce landfills, so try not to put it in the general waste.
