About Thornleigh
Thornleigh sits at the intersection of Sydney's Upper North Shore and Hills District, straddling Hornsby Shire Council territory. Named for its elevated ridge position (hence "thorn" + "legh" — a hill), the suburb is anchored by Thornleigh Railway Station and the Thornleigh Marketplace shopping hub. Most homes were built in the 60s–80s and sit on substantial blocks under deep eucalypt canopy — the defining landscape feature. Pennant Hills Road runs through the district as the main arterial, with tree-lined residential streets branching north and south. For homeowners, Thornleigh's proximity to both the railway and established shops makes it attractive, but the canopy cover means constant leaf tannin staining is an inevitable maintenance cost.
Thornleigh sits in the Hornsby Shire Council LGA, part of the broader Upper North Shore region. Most of our jobs here fall within a 10–15 minute drive of Thornleigh Railway Station, and we regularly service streets around Thornleigh Marketplace and Pennant Hills Road. Neighbouring suburbs we cover in the same run include Pennant Hills, Normanhurst, Westleigh, Hornsby.

Soft washing
We use a low-pressure soft-wash system tuned for rendered, painted and brick exteriors. The chemistry does the cleaning — not the pressure — so paint, render and cladding stay intact. See our full House Washing Sydney guide →
We walk every elevation, protect fixtures and set up low-pressure rigs tuned to your siding.
Specialised detergents break down mould, mildew and spiderwebs without harming paint or landscaping.
Calibrated pumps rinse contaminants away, leaving a uniform, streak-free surface.
Our process kills organic growth at the root so your facade stays cleaner for longer.

Common issues we see on Thornleigh homes — the reasons your neighbours are booking us.
Eucalypt tannin stains light-coloured render and painted surfaces orange-brown
South-facing walls under canopy hold moss and algae year-round
Fascia and eave boards accumulate leaf litter and bird droppings
Paint chalks on west-facing walls exposed to afternoon sun through canopy gaps
Weatherboard joints on heritage homes trap stringybark and decompose, weakening paint seals
Rendered skirtings and entry thresholds absorb ground-level tannin splash during heavy rain
Housing stock: Thornleigh carries classic north-shore housing stock — 60s–80s full-brick homes on leafy blocks, plus 2000s+ brick-veneer and rendered renovations. Most properties sit under established eucalypt canopy, which means leaf-tannin stain is the defining cleaning challenge. Roofs are mostly terracotta or concrete tile, with Colorbond re-roofs on renovated stock.
Climate: Upper North Shore climate — cooler, wetter, heavier canopy than Hills District. Leaf tannin running off the eucalypts after rain is the #1 source of render staining. Lower dust, more humidity.
How often: Every 12–18 months. Light-coloured render and painted weatherboard under canopy closer to 12 months.

Timing
Autumn (March–May) is the ideal window for soft-washing Thornleigh homes. Tannin staining peaks in autumn as eucalypt leaf drop accelerates, but temperatures drop and drying times improve post-wash. Spring (September–October) is the second-best window for pre-storm season preparation. Avoid mid-summer heat, which slows the oxalic-acid pre-treatment reaction and risks paint softening on west-facing walls. Winter rain is heavy and can re-stain freshly cleaned surfaces, so schedule the clean 2–3 weeks before the major rainfall window for best results.
Recommended cycle: Every 12–18 months. Light-coloured render and painted weatherboard under canopy closer to 12 months.

Real questions we hear from Thornleigh customers every week.
Yes — Thornleigh sits on the Hills–North Shore border and we service it weekly. We cover every street from the station down to Pennant Hills Road. Free on-site quotes within 24 hours.
Yes — eucalypt tannin is the defining soft-wash challenge in Thornleigh. We use a specialised oxalic-acid-based pre-treatment, dwell, then soft-wash rinse. Tannin staining that looks permanent usually comes off in the first pass. If not, we include one follow-up pass at no extra charge.
Every 12–18 months for most brick homes. Light-coloured render and painted walls under direct eucalypt canopy should book closer to 12 months because tannin staining accumulates fast and is easier to remove before it sets.
Single-storey 4-bed homes start at $350. Two-storey Thornleigh homes with tannin-heavy facades run $500–$650 including pre-treatment. Painted weatherboard or shingle-clad heritage homes may run $700+. All quotes are fixed.
Yes — a pre-wash gutter clean is a natural add-on because blocked gutters cause water-stain tracks down fresh render. We can quote both together — most Thornleigh customers bundle them.
Yes — heritage weatherboard (common on older Thornleigh stock) is delicate but responds well to low-pressure soft-wash. We never use high PSI on timber cladding. The real risk is trapped water in joints — we ensure the building dries properly after wash and we can pre-treat seams with a mildew inhibitor if needed.
Soft-washing removes dirt and algae that accelerate paint chalk and failure, but it can't reverse damage already done. If paint is peeling or bubbling, the substrate underneath needs attention first — usually a paint specialist job. We recommend a professional painter inspect the walls after a soft-wash so you can prioritise repainting.
No — soft-wash is low-pressure (under 100 PSI) and won't damage render, stucco, or acrylic coatings. The tannin pre-treatment works chemically, not through force. Render actually benefits from soft-wash because it removes trapped moisture sources (moss and algae) that cause long-term damage.
