CRACK REPAIR AND REINFORCEMENT FOR STRONGER EXTERIORS
If you've noticed cracks in your plaster, areas where plaster has fallen off, or damp spots, it's a good idea to get those areas looked at promptly.
Undertaking quality repairs early on can help to prevent bigger issues from developing, which may necessitate a full reclad.
Our team can assess the problem, offer advice on the best solution and then carry out repairs or recladding as necessary. Contact us to arrange a quote for repairs or talk to us about commercial plastering or residential plastering for renovations or new builds.
Repairs & Maintenance - Overview:
Plaster repairs, retexturing, waterproofing and repainting for exteriors.
- Solid plaster repair for exterior cracks, damp patches and damage
- Inspection to identify the cladding system, movement and older repairs
- Moisture and weak-point checks for hidden water entry risks
- Targeted waterproofing is applied only where water could get in
- Plaster cladding repairs with patching and blended finishes
- Retexturing or replastering for damaged areas
- Recladding work when existing exterior plaster systems have failed
- Exterior plaster painting after repairs using weather-suited paints
Poor Application
If the original plaster was applied poorly, for example, through incorrect mixing or using substandard materials, this can lead to deterioration down the line.
Moisture
Water can seep into the plaster due to inadequate waterproofing or condensation due to poor ventilation.
Temperature Changes
Fluctuating temperatures can cause buildings to expand and contract, which can cause cracks.
Seismic Activity
Even minor earthquakes or ground movement can cause your property to move and damage the plaster.
- Early wall repairs keep water out and stop small problems from growing
- Careful plaster repairs or recladding can freshen up your property and help keep it up to date
- Plaster cladding repairs and repainting protect your property against local weather conditions

FULL ASSESSMENTS ENSURE THE RIGHT REPAIR PROCESS
Before we start work on any repairs, we'll conduct a full assessment of the area. This includes checking:
- Which cladding system is on your property
- The age of the plastering
- Any previous repairs or restoration work that has been carried out
- Where hidden moisture or weak points are
- Any areas where water is trapped
- Any areas where the building appears to have moved, affecting the plaster
- The full spread of cracks, not just those on the surface
Plaster repairs are based on what your property actually needs, not a one-size-fits-all fix. We'll keep you informed as to what's required - whether that's spot repairs, restoration or full re-cladding.
OUR TEAM GOES BEYOND SURFACE REPAIRS FOR A BETTER FINISH
If your plaster is cracked, damaged or at worst leaking, then superficial surface patching won't fix the problem.
At Central Plastering, we go further to ensure the repair is completed properly and in a way that will prevent further issues. Potential repairs include:
- Reinforcing cracks at high-stress spots
- Fixing places where movement keeps happening
- Sorting drainage so water cannot get trapped
All repairs are carefully blended into the original exterior, so your property looks tidy.
If your commercial property is an older building that doesn’t meet current earthquake safety standards, or if there are significant cracks that could affect the strength of the walls, our team can help by installing the SEISMOLOCK GRC strengthening system.
The SEISMOLOCK GRC system uses a specially engineered reinforced plaster to create a strengthening layer over existing brick or masonry surfaces to help improve the structural integrity of your building and increase its resistance to seismic activity.
Applied directly to the wall surface, traditional cement render is made from a mix of cement, sand and lime. IT is a very durable option and can be finished in a variety of textures.
Stucco is a traditional method that involves adding multiple layers of cement-based plaster over a wire mesh. It can be finished in a range of textures and colours.
These cladding systems usually involve plaster applied over a solid substrate such as concrete block, fibre-cement board or brick. Monolithic cladding offers a clean finished look and, when installed by Central Plasterers' quality tradesmen, will offer a durable, problem-free cladding for years to come.
In these systems, a polymer-based exterior plaster is applied over an insulating foam board, offering excellent thermal insulation and flexible design options. EIFS is also known as synthetic stucco.
These are cement-based plasters which have been modified with polymers to enhance performance. These systems offer better adhesion, flexibiltiy and water resistance.
These acrylic-based resins are often used as a finishing coat over a substrate or other types of plaster. They offer good durability and water resistance and provide a stylish finish.
RETEXTURING, REPLASTERING AND WATERPROOFING
If your building's exterior needs a new lease of life, then retexturing and replastering can give your exterior a clean slate. Options include:
- Retexturing to refresh tired exteriors
- Replastering damaged or uneven areas to create a smoother surface
- Recladding when the old system no longer works
We can also carry out external waterproofing, but we do this only where water could get in, so you are not paying for extras you do not need.
After plastering, exterior repainting can be undertaken to give a tidy, sealed finish. You get:
- Surfaces prepped and ready for painting
- Paints chosen for local weather
- Qualified tradespeople for each stage
Ongoing cracks, bubbling, soft spots or water marks after rain are signs your exterior needs a check. Inspections look for hidden water, failed joins and likely leak points, not just what you can see. Dealing with these early usually means a simpler fix instead of a major job.
Repairs are matched to your current finish wherever possible. This covers texture, sanding and using products that move with your property. If an exact colour match is not possible, you get clear advice on repainting for an even look.
Yes, repainting is completed after repairs. Paints are chosen for the local conditions and include breathable options if needed. All surfaces are prepared for a consistent, long-lasting finish.
Cracks tend to return due to ongoing movement, water getting in or earlier repairs that only covered the surface. Inspections check for movement, leaks and failed joints to get to the root of the problem and make sure repairs last.
Yes, STO and Rockcote repairs follow the correct methods and products for each system. The process is explained before work starts and your property is kept tidy from start to finish.
