Wall Crack Repairs in Melbourne & Across Victoria

Cracks in your walls aren’t just an eyesore — they’re your home’s way of warning you that something deeper is shifting. At Perfectly Restumping & Underpinning, we don’t just cover cracks with filler. We identify the root cause, stabilise the foundation, and deliver permanent repairs so those cracks don’t return.

Underlying Issue & Solution

From hairline fractures in plaster to step cracks running through brickwork, wall cracks are one of the most common reasons homeowners call us. But in our 30+ years of experience, we’ve found that cracks are rarely “just cosmetic.”

Most are caused by underlying issues such as sinking stumps, uneven floors, or shifting foundations. Simply patching over the damage won’t solve the problem — it will almost always return.

That’s why our focus is on diagnosis first: identifying whether the issue comes from your subfloor, stumps, or soil conditions. Once the foundation is stabilised through reblocking, levelling, or underpinning, wall cracks can be repaired with confidence.

Types of Wall Crack Repairs We Provide

Mortar Joint Repointing

For smaller cracks in brickwork, we carefully remove the affected mortar and replace it with fresh, matching mortar. This strengthens the wall and restores its appearance.

Structural Reinforcement

When cracks indicate movement, reinforcement may be required. We stabilise the affected area using steel bars, helical ties, or epoxy resins designed for structural repairs.

Foundation Repairs & Underpinning

If cracks are caused by foundation movement, we fix the cause, not just the symptom. This may involve underpinning or restumping to stabilise the structure before repairing the wall itself.

Our Wall Crack Repair Process

01

Inspection & Diagnosis

We begin with a thorough site inspection, assessing crack patterns, soil conditions, and foundation strength.

02

Stabilisation Plan

If movement is detected, we design a tailored plan to stop it — from reblocking failing stumps to underpinning deeper foundations.

03

Repair & Reinforcement

Cracks are repaired using the most suitable method: repointing, reinforcement, or full structural restoration.

04

Finishing & Monitoring

Repairs are blended seamlessly with the existing wall. Where necessary, we return for follow-ups to ensure cracks remain closed.

If you are looking for high quality restumping and leveling your house, do not look anywhere else. This is your MAN and you will be in good hands. I wish I could give a 10 star rating for this company. Mike is top-notch professional. His quote was very competitive, and he was extremely punctual, humble, understanding, supportive, and the quality of their work is second to none. His crew reflect his values as well. They were always on time, and hardworking and supportive. He really saved us a lot of time by starting just 3 days after he visited the site. He applied for all the necessary permits and goes by the book. His work is transparent and he is very responsive and supportive throughout the process. We very grateful for this team for their support and professionalism that are very hard to match!

Mike did an excellent job with the house levelling and re-stumping at my place. He was professional, reliable, and clearly very experienced. He took the time to explain everything clearly, and the quality of his work really shows. The house feels solid and level now, and the whole process was smooth from start to finish. Highly recommend Mike if you need re-stumping or foundation work done!

These guys are the real deal.  When I read their 5 star reviews I was impressed.  I then had Matt out to quote my job. He was professional and knew exactly what he was talking about.  The boys came and completed the job and were excellent. Smooth work no cracking or tiles breaking just excellent work. I highly recommend

"Communication" - this is what was significant for this job to go smoothly. Mike is a professional, he does not disappear if things went pear shaped, he found a solution. There may have been issues during the job however open communication meant that Mike presented a solution that would fix the problem within tolerance, considering the house is over 40 years old.

Would not hesitate to use his services again and would highly recommend.

Perfect experience from start to finish! Great communication, professional, polite and punctual. They explain everything. And answer all your questions. Reasonable pricing. No damage. They organise permits and inspections and clean up too. I had my floors relevelled and some additional stumps put in. Special thanks to Mike and Murray. They made what seemed a daunting project to me- a walk in the park. Highly recommend.
