Small holes, cracked plaster and damaged walls are common problems in homes throughout Sydney.
Whether it’s a dent caused by moving furniture, a hole left behind after removing a wall-mounted television or cracks appearing around a doorway, even minor plaster damage can affect the appearance of a room.
Fortunately, many small plaster repairs can be completed without replacing an entire wall or ceiling.
But how much should you expect to pay?
The cost of small plaster repairs depends on the size of the damaged area, the type of surface, the materials required and how much preparation is needed to achieve a smooth finish.
In this guide, we’ll break down the indicative costs of common plaster repairs, explain what affects the price and help you understand when hiring a professional plasterer is worthwhile.
What Is the Average Cost of Small Plaster Repairs in Sydney?
Small plaster repair costs vary depending on the type of damage and the amount of work involved.
Although some repairs appear simple, achieving a smooth, consistent finish can require several stages of preparation, patching and sanding.
How Much Does It Cost to Repair a Small Hole in a Plaster Wall?
Small holes are among the most common plasterboard repairs.
They can occur when removing picture hooks, shelving, curtain brackets, televisions or other wall-mounted fixtures.
The cost depends on the size and depth of the hole, along with the condition of the surrounding plasterboard.
Small Nail and Screw Holes
Tiny holes left behind by picture hooks or screws are generally straightforward to repair.
A plasterer may need to remove loose material, apply suitable filler, sand the area and prepare the surface for repainting.
Although the repair materials are relatively inexpensive, a professional contractor may apply a minimum job charge.
For several small holes, arranging one visit may be more economical than booking separate repairs.
Small Impact Holes
Small impact holes caused by door handles, furniture or accidental knocks may require more preparation.
If the plasterboard surface has been punctured, simply filling the opening may not provide a suitable finish.
Depending on the damage, a professional plasterer may reinforce the area or install a small patch before applying finishing compound.
Medium-Sized Holes
Larger holes may require removing the damaged plasterboard and installing a replacement section.
The new patch needs to be securely supported, jointed and finished so that it blends into the existing wall.
For this type of repair, a preliminary budget might be approximately 250–500, although complex repairs can cost more.
How Much Does It Cost to Repair Cracks in Plaster Walls?
Cracked plaster is another common issue in residential properties.
Some cracks are cosmetic, while others may indicate movement or an underlying problem that requires investigation.
Hairline Cracks
Hairline cracks are thin cracks that may appear around corners, joins or other areas of a wall.
Minor cosmetic cracks can sometimes be repaired by preparing the surface, applying suitable materials and finishing the area.
However, the cause of the cracking should be considered before repairs begin.
Cracks Around Doors and Windows
Cracks can sometimes appear around door frames, window openings and other areas where different building materials meet.
These areas may experience movement over time.
A plasterer can assess the visible damage and determine whether a cosmetic repair is appropriate.
Where significant or ongoing movement is suspected, a suitably qualified building professional may need to investigate.
Recurring Cracks
If a crack returns shortly after being repaired, repeatedly filling it may not solve the problem.
The underlying cause needs to be identified.
Depending on the situation, the repair may require reinforcing the affected area or addressing movement before the plaster is refinished.
For homeowners, the important distinction is between repairing the appearance of a crack and resolving the reason it developed.
Why Do Small Plaster Repairs Sometimes Cost a Few Hundred Dollars?
It’s understandable to question why a small plaster repair can cost several hundred dollars when the damaged area may only be a few centimetres wide.
However, professional plastering involves more than applying filler.
A typical repair may include:
- Travelling to the property and assessing the damage.
- Protecting nearby furniture, floors and surfaces.
- Removing loose or damaged plasterboard.
- Preparing the repair area.
- Installing a patch or reinforcement where required.
- Applying jointing or finishing compounds.
- Allowing sufficient drying or setting time.
- Sanding and preparing the surface for painting.
Some repairs may require more than one visit.
A contractor also needs to account for tools, equipment, materials and the time involved in completing the job.
This is why a minimum project charge can apply even when the visible damage is relatively small.
Is It Cheaper to Repair Multiple Holes at Once?
In many cases, yes.
If you have several small holes or cracks throughout your property, arranging for them to be repaired during one visit may offer better value.
For example, imagine you have three small holes in a living room, two damaged areas in a bedroom and several cracks along a hallway.
Booking a separate appointment for each repair could involve repeated travel and setup costs.
By identifying all damaged areas beforehand, a plasterer may be able to complete the work more efficiently.
How to Prepare for a Multiple-Repair Quote
Before contacting a plasterer:
- Walk through the property and identify each damaged area.
- Take photographs of the holes, cracks or surface defects.
- Record approximate dimensions where practical.
- Note whether the damage is on a wall or ceiling.
- Mention any previous repairs or known water damage.
Providing clear information can help the contractor understand the scope of work and determine whether an inspection is necessary.
What Types of Small Plaster Damage Can Be Repaired?
Professional plasterers can address a wide range of common wall and ceiling problems.
Door Handle Damage
When a door opens too far, the handle can strike the wall and create a dent or hole.
Depending on the severity, the damaged area may require filling or a plasterboard patch.
Installing a suitable doorstop afterwards can help prevent the damage from recurring.
Damage from Removing Wall Fixtures
Removing shelving, brackets, mirrors or televisions can leave holes and damaged plasterboard.
Some fixtures also remove sections of the paper surface when detached.
A professional repair can help restore the wall before repainting.
Furniture Damage
Moving furniture through narrow hallways or bedrooms can cause dents, scratches and chipped plaster.
These areas may be repaired by preparing the damaged surface and applying suitable finishing materials.
Water-Damaged Plaster
Small water stains or softened plasterboard may indicate a leak.
Before repairing the visible damage, the source of moisture should be identified and resolved.
If the plasterboard has deteriorated, replacing the affected section may be necessary.
Damaged Cornices
Cornices can develop cracks, chips or gaps over time.
Standard cornices may be relatively straightforward to repair, while decorative or heritage-style cornices can require specialist techniques.
Can You Repair Plasterboard Without Replacing the Whole Wall?
Yes. In many situations, a damaged section of plasterboard can be repaired or replaced without removing the entire wall.
For example, a hole caused by an accidental impact may only affect a small area.
A plasterer can remove the damaged section, install a suitable replacement patch and finish the joints.
The surrounding plasterboard can remain in place if it is sound and suitable.
This approach can reduce unnecessary demolition and help keep the project manageable.
However, if the damage is widespread or the existing plasterboard is deteriorated, more extensive replacement may be required.
Plasterfix provides small and large plaster patch repair services in Sydney for homeowners and property managers.
Should You Repair Small Plaster Damage Before Painting?
Yes. Repairing visible damage before painting is generally worthwhile.
Fresh paint can improve the appearance of a room, but it will not necessarily hide dents, cracks or uneven plasterwork.
In fact, some imperfections can become more noticeable after painting, particularly under direct or angled lighting.
Preparing the surface correctly can help achieve a smoother finish.
For example, a patched wall may require sanding and priming before applying the final paint coats.
If you’re repainting an entire room, arranging plaster repairs beforehand can help avoid having to repaint sections later.
Should You Repair Plaster Damage Before Selling or Renting a Property?
Small plaster defects may seem insignificant, but they can affect the overall presentation of a property.
Visible holes, cracked corners and damaged walls can make rooms appear poorly maintained.
For homeowners preparing to sell, completing minor plaster repairs can help create a cleaner and more appealing interior.
For landlords and property managers, repairs may also form part of routine property maintenance or preparing a property for new occupants.
The goal is not necessarily to replace large sections of plasterboard, but to identify the most appropriate way to restore damaged surfaces.
Plasterfix works with residential properties, strata managers and real estate clients across Sydney, providing services ranging from minor patch repairs to larger plaster restoration projects.

Is DIY Plaster Repair Worth It?
Some homeowners choose to repair small holes themselves using products from a hardware store.
For very minor cosmetic damage, this may be a reasonable option.
However, DIY repairs can become more challenging when the damage is larger, the plasterboard is broken or the surrounding surface is uneven.
Common issues include:
- Applying too much filler.
- Failing to reinforce a damaged section.
- Leaving visible edges around the repair.
- Sanding unevenly.
- Painting before the surface is properly prepared.
- Repairing a crack without investigating why it appeared.
A poorly finished repair may become more noticeable once painted.
Hiring a professional plasterer can be particularly worthwhile when repairing several areas, working on prominent walls or preparing a property for sale.
How Long Do Small Plaster Repairs Take?
The time required depends on the size and type of damage.
A simple cosmetic repair may involve a relatively short amount of hands-on work.
However, larger holes or multiple damaged areas may require several stages.
Some compounds also need time to dry before sanding or applying additional coats.
As a result, a repair that takes only a short time to prepare may not be ready for painting immediately.
A professional plasterer should explain the expected timeframe and whether a return visit is necessary.
Frequently Asked Questions About Small Plaster Repairs
What is the cheapest way to repair a small hole in plasterboard?
For very minor cosmetic holes, a suitable DIY filler may be an option. Larger holes or damage requiring reinforcement are generally better assessed by a professional.
Can a plasterer fix several holes in one visit?
Often, yes. Combining several repairs can be a practical way to reduce repeated setup and travel costs.
Will a repaired wall look the same as before?
A properly completed repair should provide a smooth surface that blends into the surrounding wall. Final appearance also depends on appropriate priming, paint matching and finishing.
Does a plaster repair quote include painting?
Not always. Confirm whether painting is included or whether the repaired surface will be left ready for a painter.
Can a plasterer repair cracks that keep coming back?
A plasterer can assess the visible cracking and recommend suitable repair work. However, recurring cracks may require investigation of an underlying movement or moisture issue.
