Rising damp is not just water on a wall..

Common stages of rising damp include:

•Damp marks near the base of walls
•Peeling paint or bubbling plaster
•White salt staining on the surface
•Crumbling mortar or brickwork
•Ongoing wall deterioration if left untreated

This is why proper diagnosis matters. Covering the surface will not fix the source.

MJ Reilly Constructions provides rising damp solutions, DPC injection, brickwork repairs, waterproofing and remedial building works across Illawarra and South Sydney.

Cavity flashing is a small detail with a big role in protecting a building.

When flashing fails or is missing, water can travel through the wall cavity and cause damage to brickwork, internal finishes, structural elements and surrounding areas.

This project involved targeted cavity flashing works to help manage water movement and protect the building envelope for the long term.

We provide remedial building repairs across Illawarra and South Sydney, including cavity flashing replacement, brickwork repairs, waterproofing, lintel replacement and structural repairs.

When was the last time you checked your balcony?

Cracks, loose tiles, damaged grout, staining or signs of water ingress can point to problems below the surface.

From damaged to restored.

This brick wall repair shows how the right remedial approach can restore both the appearance and integrity of a property.

A completed residential structural repair project.

This job required more than a simple repair. We managed the design, coordinated the engineering, and completed the construction works, giving us full control over the process from assessment through to final delivery.

By handling both the design and ex*****on, we were able to create a repair solution that suited the existing structure, site conditions and engineering requirements.

This is where experience matters. Structural issues need to be properly assessed, planned and repaired, not just covered over.

Project delivered in Woonona.

This bathroom and ensuite were completely stripped back due to defective waterproofing in the original space.

The works included re-framing, waterproofing membrane, screeding, membrane application, and tiling to restore the area with a proper long-term repair approach.

When waterproofing fails, the damage can extend beyond the visible surface, which is why the correct preparation and installation process is so important.

MJ Reilly Constructions provides bathroom refurbishment and remedial waterproofing solutions across Illawarra and South Sydney.

Cracks above your windows or doors can be more than a surface issue.

Rust staining, sagging masonry, loose bricks, or movement around openings can be signs that your lintel may need attention.

Lintels play an important role in supporting the brickwork above windows and doors. When they deteriorate, the damage can spread and become more costly to repair.

Book an inspection to understand what is happening behind the damage.

Thinking about building or renewing your deck?

Decking is more than installing timber boards. Proper spacing, structural framing and correct fixings are essential to ensure the deck remains stable and durable over time.

A well-built deck can transform your outdoor space and create the perfect area to relax or entertain. With quality construction and the right materials, your deck can handle weather and daily use for years.

MJ Reilly provides decking and outdoor construction across South Sydney, St George, Sutherland Shire, Wollongong and the Illawarra.
