Building & Pest Inspections in Mullaloo
Mullaloo is a sought-after beachside suburb anchored by one of Perth's best family beaches — Mullaloo Beach. The suburb sits on Quindalup Dunes near the coastline, transitioning to Spearwood Dunes (Karrakatta Sand) further inland. The housing stock spans the 1970s through 1990s, with ocean-facing properties commanding premium prices and driving renovation and knock-down rebuild activity. Inland properties remain as original 1970s–1980s brick-and-tile family homes on larger blocks, creating a diverse inspection environment across the suburb.
The beachside position means all Mullaloo properties face some degree of coastal exposure — salt spray, wind-driven rain, and the accelerated corrosion that characterises ocean-adjacent construction. Properties on the elevated western blocks experience the most intense exposure, but even homes several streets back from the beach are affected during severe winter storms.
What We Look For in Mullaloo Properties
Coastal Deterioration in 1970s–1980s Stock
The combination of coastal exposure and 40–50 year age creates compounded deterioration in Mullaloo's original housing stock. Galvanised steel components — lintels, wall ties, roof tie-downs, valley trays — corrode faster in the marine environment. In 1970s homes now 50 years old, lintel corrosion is often advanced, with rust expansion cracking the brickwork above window and door openings. Wall tie corrosion is widespread, particularly on the western (ocean-facing) elevations that receive the most salt-laden wind. Our inspectors systematically assess metal component condition across all elevations, prioritising exposed faces.
Renovation Quality Assessment
Mullaloo's beach lifestyle appeal drives significant renovation activity — particularly in properties within walking distance of the beach. Renovations range from high-end architect-designed additions to budget cosmetic updates. Common issues include rear additions where the new roof doesn't properly tie into the original structure (causing leaks at the junction), load-bearing walls removed without adequate structural replacement, and bathroom renovations where waterproofing was done to budget rather than to standard. Our inspectors assess whether renovation work is structurally sound and properly integrated with the original building.
Concrete Roof Tile and Structural Assessment
The inland sections of Mullaloo — east of Oceanside Promenade — contain the suburb's original 1970s–1980s brick-and-tile stock. Concrete tiles at this age have lost their protective glaze and absorb moisture. Combined with coastal UV exposure, the tiles become brittle and prone to cracking. Original pine roof trusses show deflection from the accumulated weight of saturated tiles. Ridge capping mortar has cracked across most original roofs. Our inspectors assess roof condition from both outside and inside the roof space, checking tile integrity, sarking condition, timber framing, and evidence of past or active roof leaks.
Sand Dune Foundation Stability
Mullaloo's elevated coastal blocks sit on Quindalup Dune sand that was cut and filled during original subdivision. Properties on the higher terrain west of Mullaloo Drive may sit on fill of variable quality. Where retaining walls have failed or drainage is inadequate, sand migration can undermine paving, footings, and external structures. Our inspectors check for evidence of sand movement, retaining wall adequacy, and drainage effectiveness on elevated coastal blocks.

Pest Control in Mullaloo
While Mullaloo's coastal position limits some pest species found in sheltered inland suburbs, the sandy soils remain highly conducive to subterranean termite foraging. Tom Simpson Park and the suburb's internal green spaces harbour termite colonies that forage into surrounding residential properties. Properties with mature gardens, aging reticulation systems, and garden beds built against external walls are most at risk — the moisture from irrigation and leaking pipes sustains termite activity even through Perth's dry summer.
Coastal brown ants are a persistent issue in Mullaloo's sandy soils, undermining paving and creating subsidence around outdoor areas. Rodent activity peaks in autumn and winter as roof rats migrate from the coastal scrub and parkland into heated roof spaces. Redback spiders are consistently found in meter boxes, garden sheds, and sub-eave spaces throughout the suburb. Our pest control services start from $189, with annual termite inspections from $189.
