1. How Much Does It Cost to Pressure Wash a House?
Professional house exterior cleaning (walls) in the Gympie/Noosa/Sunshine Coast area typically ranges from $400 to $1,000 for a single-storey home, with many standard jobs falling between $500 and $800. Two-storey homes usually start from $800–$1,900+.
Prices are often calculated per square metre of wall surface ($1.50 – $4 per m² is common locally) or as a flat rate depending on size, condition, access, and whether roof cleaning is included. Heavily moulded or north-facing walls cost more.
Note: “Pressure washing a house” can mean different things. Many homes in our region benefit more from soft washing (low-pressure + specialised cleaning solutions) than high-pressure blasting. At Impressions Property Cleaning, we assess every property and recommend the safest, most effective method.

2. Should I Pressure Wash or Soft Wash My House Exterior?
For most homes on the Sunshine Coast and in Gympie/Noosa, soft washing is the better choice.
• Pressure washing uses high PSI water to blast away dirt. It works well on hard surfaces like concrete driveways but can damage painted surfaces, weatherboard, render, vinyl, and push water behind cladding.
• Soft washing uses low pressure combined with biodegradable cleaning solutions that kill mould, algae, and lichen at the root. Results last longer (often 12–24+ months vs 6–12 months for pressure washing alone) because it treats the biological growth rather than just the surface.
In Queensland’s humid, subtropical climate, black mould and algae return quickly if only blasted off. Soft washing is gentler, safer for your home’s exterior, and more effective long-term.
Impressions Property Cleaning specialises in professional soft wash house washing alongside traditional pressure cleaning. We’ll advise you on the best approach for your surfaces.
3. How Much Does Driveway Pressure Washing Cost?
Driveway cleaning in our area typically costs $150 – $500, with most standard residential driveways falling between $200 and $350.
• Small/single-car driveway: $150 – $250
• Double or larger driveway: $300 – $500+
• Heavily stained or oil-marked surfaces cost more (pre-treatment required)
Local rates are often $2 – $4+ per m². Larger jobs or those combined with house washing usually offer better value.
We also clean paths, patios, and pool surrounds. Many clients bundle driveway cleaning with their house wash for a fresher overall look.
4. What’s the Difference Between Pressure Washing and Soft Washing?
Pressure High (1300-4000 + PSI )
Method Mechanical Blasting of dirt
Best for Concrete, driveways, paths, bricks
Risk of damage Higher on delicate surfaces
Longevity 6-12 months
Queensland suitability Good for hard surfaces
Bottom line: Use pressure washing for driveways and hard surfaces. Use soft washing for your house exterior and roof in our climate. Many jobs benefit from a combination of both.
5. Can I Pressure Wash My Own House or Should I Hire Someone?
We strongly recommend hiring a professional for house exteriors and roofs.
Risks of DIY:
• Damage to paint, cladding, windows, or roof tiles
• Forcing water behind weatherboards or into walls (leading to costly repairs)
• Injury from high-pressure equipment or ladders
• Ineffective results — mould returns faster
• No insurance if something goes wrong
• Using the wrong chemicals or pressure settings
Professionals like Impressions Property Cleaning have the right equipment, experience with local conditions, proper safety procedures, and insurance. We deliver consistent, long-lasting results without risking your biggest asset — your home.
6. How Often Should You Pressure Wash or Soft Wash Your House?
In the Gympie/Noosa/Sunshine Coast region:
• House exterior (walls): Every 12–18 months is ideal for most homes. North-facing or heavily shaded walls may need it more often.
• Roof: Every 12–24 months, or when you notice significant black streaking or moss.
• Driveway & paths: Every 12 months or as soon as staining becomes noticeable.
Regular cleaning prevents heavy buildup, protects your paint and roof tiles, improves curb appeal, and can even help with energy efficiency. Many of our regular clients schedule annual maintenance cleans.
7. What Questions Should I Ask Before Hiring a Pressure Washing Company?
Ask these key questions:
• Are you fully insured (public liability + workers’ compensation)?
• Do you use soft washing or high-pressure methods for house exteriors?
• What chemicals do you use? Are they biodegradable and safe for plants/pets?
• Can you provide recent before-and-after photos of similar local properties?
• Do you offer a written quote and guarantee on workmanship?
• How do you protect windows, plants, and surrounding areas?
• What experience do you have with Queensland homes and our climate?
Impressions Property Cleaning is happy to answer all these questions and provide references. We’re a local, fully insured business with years of experience on the Sunshine Coast and in Gympie.
8. Is Pressure Washing Safe for All Home Surfaces?
No. High-pressure washing is not safe for:
• Painted or stained surfaces (can strip or damage paint)
• Weatherboard, vinyl, or fibre cement cladding
• Roofs (especially tile or shingle — can dislodge granules or tiles)
• Windows and frames
• Older mortar or delicate masonry
• Eaves, gutters, and soffits (if not done carefully)
Safe for: Unpainted concrete, most brickwork, driveways, and paths (with correct technique and pressure).
This is why professional assessment and the right method (often soft washing for walls and roofs) are so important.
9. How Much Does Professional Window Cleaning Cost?
Exterior window cleaning for a typical residential home in our area usually costs $150 – $400, depending on the number of windows, height, and accessibility.
• Small to medium home: $150 – $250
• Larger homes or two-storey: $300 – $450+
Some companies offer specials (e.g. around $149 for up to 20 external windows). Impressions Property Cleaning provides premium window and glass cleaning as a standalone service or bundled with house washing.
We clean exterior windows, sliding doors, and screens carefully and efficiently.
10. Why Does My Roof Need Professional Cleaning?
Your roof takes a beating from Queensland’s sun, rain, humidity, and coastal salt air. Over time, black algae, lichen, and moss grow on tiles or metal. This isn’t just cosmetic — it can:
• Hold moisture against the roof, shortening its lifespan
• Contribute to leaks and interior damage
• Make your home look older and less appealing
• Reduce energy efficiency (dark roofs absorb more heat)
• Block gutters when debris builds up
Professional roof cleaning (usually soft wash or low-pressure methods) safely removes growth without damaging tiles or voiding warranties. DIY or incorrect high-pressure cleaning can cause expensive damage.
At Impressions Property Cleaning, we clean roofs safely and effectively as part of our exterior services.
