Seek Professional Help

As a homeowner, you can tackle many pressure-washing projects on your own. But certain situations are better left to the professionals.

For example, pressure washing tall multi-story homes introduces fall and injury hazards you cannot handle safely. Experts have specialized Gear to complete the job safely.

To avoid damage, porous surfaces such as wood and brick require specialized methods and calibrated pressure levels. The wrong pressure or technique can damage delicate materials. Professional services like Pressure Washing Nashville are trained to handle such surfaces. They use adjustable pressure and low-impact methods.

Professionals also have an arsenal of equipment beyond basic consumer washers. Powerful gas-powered pressure washers with industrial strength get tough stains off concrete driveways. Surface cleaners that attach to clean large areas quickly and use soft wash methods for eco-friendly cleaning.

Understand Pressure Washing Equipment

Selecting the correct pressure washer powers a successful cleaning. Washers come in electric or gas models. They also vary by pressure strength measured in PSI (pounds per square inch).

For home exteriors, look for medium-duty pressure washers. These generate 2000-3000 PSI, which is enough cleaning oomph without damage. Electric medium-duty washers offer plenty of residential power, whereas gas versions provide extra muscle for grimy driveways and garages.

Light-duty electric washers under 2000 PSI may not cut tough dirt. In contrast, high-end gas models over 3000 PSI may shred siding. So, stick to the 2000-3000 PSI medium-duty for optimal home cleaning.

Features like nozzles also optimize results. Adjustable wands allow precision control over water pressure for cleaning sensitive surfaces. Rotating nozzles speed cleaning of broad spaces like siding walls.

Prioritize Safety

Before wielding the mighty lance of the pressure washer, prioritize safety. Gear up with sturdy boots, pants, gloves, and goggles for protection against debris and water.

Inspect connections meticulously; a loose hose is hazardous. Engage the trigger lock whenever the washer is idle to avoid accidental spraying, which may cause injuries.

Experiment with nozzles to find the right one for each surface. The fan nozzle tackles broad areas efficiently. Use the pinpoint jet only on extremely grimy spots to avoid digging into the siding.

Identify Surface Types

Surfaces require customized pressure-washing strategies. For instance, brick and concrete can take intense scrubbing. But using too much pressure on vinyl siding may blast it away.

Research your home materials to find the recommended PSI and nozzle types. Always test first in a hidden spot.


Start low-pressure and work upwards cautiously. Patios may need a power wash to remove stains. But decks require a delicate touch and soft-wood nozzle to avoid stripping the wood bare.

Prepare The Cleaning Area

Failing to prepare the area is one of the mistakes many people make when pressure-washing. Proper setup prevents pressure washing pitfalls. Remove furniture, decor, and plants from the area.

Securely close all windows and doors. Even a tiny gap allows water to seep in and cause interior water damage. Cover vulnerable fixtures like exterior outlets with plastic shields. This prevents electrical short circuits.

Inspect the surface for loose parts. Tuck away or tape down any loose shingles, siding panels, or bricks before starting. Power washing can rapidly dislodge damaged areas and electrical short circuits.

Taking time to protect the space and possessions pays off. You can blast away freely, knowing valuables are shielded and the house is watertight.

Know Your Detergents And Cleaning Solutions

Stubborn grime and stains call for pressure washer cleaners. Quality detergents dissolve oil, grease, and mud that standard water can’t budge. For instance, degreasing agents break down lingering oil spots on driveways. Mold removers attach to and eliminate ugly black mildew streaks on the siding.

So, choose cleaners made specifically for pressure washing. Check that the formula suits the surface material like brick, wood, or concrete. Follow directions precisely; apply the solution and let it soak in for the recommended time before power rinsing. Rushing this step reduces the effectiveness.

Also, verify whether the detergent is biodegradable. Many harsh chemicals end up contaminating the ground and local water systems. Eco-friendly cleaners get the job done without environmental impact.

Use Effective Cleaning Technique

Now comes the exhilarating part: unleashing the cleaning power. Hold the spray gun safely, typically around 18-24 inches from the surface. Move it in a steady, sweeping motion, keeping it parallel to the wall.

Overlap slightly to ensure even cleaning and avoid missing spots. Rinse thoroughly with clean water, and consider using a mild cleaner for stubborn stains. Don’t blast at one spot for too long, as it can damage the surface.

Consider Regular Maintenance and Upkeep

Regular pressure washer upkeep is critical for ensuring long-lasting peak performance. After each use, flush out any detergent and clean the nozzles and hoses. Taking a few extra minutes to flush the remaining detergents will protect the inner assembly from harmful buildup issues over time.


Rinse out the nozzles, hoses, tanks, and other components that come in contact with cleaning concentrates. Give the exterior a wipe-down to remove mud, grass, and dust. Also, keep the washer stored safely in a clean, dry area after use.


Pressure washers are invaluable home maintenance tools when used correctly. With the proper preparation, Gear, and techniques, it transforms exterior surfaces by erasing years of built-up grime.

Whether DIYing or hiring a professional, protect yourself and your surrounding property while learning the best practices for targeting different materials. Mastering control of these intense sprayers brings professional-grade cleaning results.
