Pressure Washing: Quick Tips for a Spotless Home Exterior

Got a dirty driveway, grimy walls, or moldy siding? A pressure washer can blast those stains away in minutes. It’s cheap, fast, and works on most outdoor surfaces. Below you’ll find simple steps that keep you safe and get great results without a professional.

Why Use a Pressure Washer?

Pressure washing delivers a strong stream of water that lifts dirt, algae, and grease that a garden hose can’t reach. It’s especially good for removing mold on brick, cleaning oil stains from a garage floor, and brightening faded pavers. Because the water hits the surface at high speed, you use less detergent and finish the job quicker.

Another perk is cost. Buying a basic electric unit costs under £100, and a gas‑powered model for larger jobs starts around £250. You can rent a bigger machine for a day if you only need it once. The money you save on labor adds up fast, especially if you tackle regular upkeep yourself.

How to Get the Best Results

1. Choose the right pressure. For wood decks or delicate siding, stay under 1,200 PSI. Hard surfaces like concrete can handle 2,500–3,000 PSI. Too much pressure can gouge surfaces, so start low and increase only if needed.

2. Use the proper nozzle. A 25-degree nozzle gives a wide spray for large areas. Switch to a 0-degree tip only for stubborn spots—always keep it moving to avoid burning the material.

3. Prep the area. Sweep away loose debris, close windows, and cover plants with a tarp. This prevents dirt from scratching surfaces and protects your garden from chemicals.

4. Apply detergent wisely. Fill the detergent tank with a biodegradable cleaner safe for the environment. Let it sit for a few minutes to break down grime, then rinse with the pure water tip.

5. Work from top to bottom. Start high on walls and work downwards. Gravity helps the runoff carry away the loosened dirt, leaving lower areas cleaner.

6. Spot‑check for mold. If you see black patches, spray a mixture of water and a small amount of bleach (1:10) after the first rinse, let it sit 10 minutes, then give a final rinse. This kills spores and prevents regrowth.

7. Finish with a quick dry. Use a leaf blower or let the sun do the work. A dry surface reduces streaks and makes the area look instantly brighter.

Remember safety: wear goggles, gloves, and sturdy shoes. Never point the wand at people, pets, or electrical outlets. If you’re unsure about the right pressure for a surface, test a small hidden spot first.

With these tips, you can keep driveways, patios, and siding looking fresh all year. Regular light washes prevent deep grime buildup, so you’ll spend less time and money on big clean‑ups later. Ready to fire up that pressure washer? Your home exterior will thank you.
