When a building inspection highlights structural defects, timely action matters. In this Bayswater WA project, two critical issues were identified. First, sections of external brickwork required structural repointing. Second, collar ties in the roof space had been cut, compromising roof stability.

Both items were documented in a pre-purchase building inspection report. Consequently, the property required professional structural repairs to restore compliance and integrity.

What the Inspection Identified

The inspection report noted deteriorated mortar joints to sections of load-bearing brickwork. Over time, mortar can break down due to moisture, age, and general movement. When mortar weakens, the structural bond between bricks reduces. As a result, walls may become vulnerable to cracking or displacement.

In addition, the roof space revealed that several original collar ties had been cut. Collar ties are horizontal timber members that connect opposing rafters. Their purpose is to resist outward thrust and prevent roof spread. When removed or cut, the roof framing can begin to separate under load.

Because both defects were structural in nature, remedial work was required by a registered builder.

Structural Repointing of Brickwork

Repointing is often misunderstood as cosmetic work. However, in structural applications, it plays a critical role. In this Bayswater home, mortar joints had deteriorated to a level where structural stability was affected.

The repair process included:

  • Raking out defective mortar joints to an appropriate depth

  • Removing loose and friable material

  • Cleaning joints to ensure proper adhesion

  • Replacing mortar with a compatible structural mix

  • Compacting and finishing joints to restore strength and weather resistance

Importantly, the replacement mortar was selected to suit the existing brickwork. Using the wrong mortar type can create further cracking or moisture issues. Therefore, material compatibility was carefully considered.

Once completed, the brickwork regained structural continuity. Furthermore, the wall’s resistance to moisture ingress improved significantly.

Installation of New Collar Ties

The second defect involved altered roof framing. During the inspection, it was observed that original collar ties had been cut. This modification likely occurred during previous works. However, removing structural members without engineering approval can compromise roof performance.

Collar ties are essential in pitched roofs. They help:

  • Prevent rafters from spreading outward

  • Reduce load transfer to external walls

  • Improve overall roof stability

  • Maintain structural geometry under wind uplift

To rectify the issue, new structural collar ties were installed at compliant spacing. Structural grade timber was used. Additionally, fixings were selected in accordance with current standards to ensure adequate load resistance.

The installation restored the roof’s ability to resist lateral forces. As a result, the structural defect identified in the building inspection report was fully addressed.

Why Prompt Structural Repairs Matter

In suburbs such as Bayswater WA, many homes are several decades old. While solidly constructed, ageing materials and previous alterations can create hidden risks. Therefore, building inspection findings should never be ignored.

Structural brickwork defects may worsen if left untreated. Mortar deterioration can allow water penetration, leading to further degradation. Similarly, compromised roof framing may lead to ceiling cracking, wall movement, or long-term distortion.

By addressing both the brickwork and roof framing promptly, the property’s structural integrity was protected. Moreover, the repairs provide peace of mind for current and future owners.

Before and After Improvements

This project clearly demonstrates the value of corrective structural work.

Before repairs:

  • Deteriorated mortar joints in load-bearing brickwork

  • Compromised roof stability due to cut collar ties

  • Structural defects documented in inspection report

After repairs:

  • Repointed brickwork with restored bond strength

  • New compliant collar ties installed

  • Structural integrity reinstated

Including before and after images in this blog will visually reinforce the scope of work. It also helps prospective clients understand the importance of proper remediation.

Structural Repairs in Bayswater WA

At Perth Master Building Services, we regularly rectify structural defects identified in building inspections. Many issues involve altered framing, ageing brickwork, or non-compliant modifications.

Importantly, structural repairs must go beyond cosmetic patching. The underlying cause must be addressed. In this Bayswater property, both defects required practical, compliant solutions.

If you have received a building inspection report noting structural concerns, early intervention is recommended. Clear communication, compliant workmanship, and correct materials are essential.
