Our houses have taken a real beating this year. Intolerable rain in the Hunter along with coal dust and parching sunshine (on occasion) has meant our cladding, bricks, windows and pathways are looking a little worse for wear. The real problem is that when you walk past your house every day, you don’t even see the change.
Your home’s exterior is the very first thing people notice. Over time, dirt, mold, mildew, algae, and grime build up — leaving your property looking tired and neglected. A simple coat of paint or landscaping can help, but nothing refreshes a home’s appearance as quickly and effectively as pressure washing your house.
Pressure washing not only restores curb appeal, but it also helps protect your property from long-term damage caused by moisture, mold, and dirt buildup. Whether you’re looking to do it yourself or hire a professional, this guide covers everything you need to know: when and how to pressure wash, areas to focus on, safety tips, costs, and more.
1. What is Pressure Washing and Why Does Your House Need It?
Pressure washing is the process of using a high-powered water spray to remove dirt, stains, algae, and other build-up from exterior surfaces. Unlike regular hosing, a pressure washer delivers water at a much higher PSI (pounds per square inch), making it powerful enough to blast away years of grime.
Benefits of Pressure Washing:
-
Restores curb appeal – Your home instantly looks fresher and more inviting.
-
Prevents long-term damage – Mold and algae can eat away at siding, brick, and paint if left untreated.
-
Protects health – Pressure washing removes allergens like pollen, mold spores, and dust.
-
Increases resale value – A clean exterior can add 5–10% to your home’s value, according to real estate experts.
Pressure washing is more than cosmetic. It’s an important part of home maintenance that protects your investment.
2. When is the Best Time to Pressure Wash Your House?
Timing matters. The best time to pressure wash is when your home is dry and temperatures are mild.
-
Spring – Perfect for washing away pollen, mold, and winter residue.
-
Autumn – Removes leaves, dirt, and mildew buildup before cooler months.
How often should you pressure wash?
Most homes should be pressure washed every 1–2 years, but this can vary depending on:
-
Climate – Humid environments promote algae and mold growth, requiring more frequent cleaning.
-
Location – Homes near busy roads or trees may accumulate dirt and sap faster.
-
Exterior Material – Vinyl siding may need cleaning more often than brick.
Signs your house needs pressure washing:
-
Green or black streaks on siding.
-
Moldy or stained driveways and patios.
-
A dull, dirty look that doesn’t wash off with a hose.
3. Areas of Your Home That Benefit Most from Pressure Washing
Not every surface should be pressure washed the same way. Here’s where pressure washing makes the biggest impact:
-
Siding (vinyl, brick, cement) – Removes mold, dirt, and mildew.
-
Driveways & Walkways – Gets rid of oil stains, tire marks, and dirt.
-
Decks & Patios – Restores natural wood or cleans stone pavers.
-
Fences – Refreshes wood or vinyl fences, making them look new again.
-
Roofs – Should be cleaned with soft washing, not high-pressure, to avoid damage.
Caution: Avoid using high-pressure water on windows, stucco, or older wood, as these surfaces can be damaged.
4. How to Pressure Wash Your House Safely (Step-by-Step Guide)
Pressure washing is effective, but if done incorrectly, it can damage siding, strip paint, or even cause injuries. Here’s a safe step-by-step approach:
Step 1: Preparation
-
Inspect your home for cracks, loose paint, or damaged siding.
-
Cover plants, outdoor furniture, and electrical outlets.

Close windows and doors.
Step 2: Gather Equipment

Wide spray nozzle.

-
Keep nozzle 6–12 inches from the surface.
-
Use long, overlapping strokes to avoid streaks.
-
Rinse thoroughly.
Step 4: Safety Reminders
-
Never aim at people or pets.
-
Avoid ladders — the recoil can knock you off balance.
-
Test pressure on a small hidden area first.
