Things You Should and Shouldn’t Pressure Wash Around the House.

Pressure washing can be a valuable tool in maintaining a home, but you must be careful not to get carried away. Pressure washing can cause more harm than good on some household surfaces. On these surfaces, pressure washing can lead to expensive damages that require costly repairs. If you do not feel comfortable pressure washing your exterior surfaces, you can seek the expertise of a pressure washing contractor in Orlando.

Asphalt shingles

If you're planning to pressure wash surfaces around your house, it is crucial never to pressure wash asphalt shingles. The high-level water pressure will strip away the granules that are in place to protect your roof. In addition, pressure washing in high areas can be very dangerous. Pressure washing equipment can cause a powerful recoil when you squeeze the trigger on the spray wand that can cause you to be unbalanced and possibly knock you off of a ladder.

Electric panels

The electric panels on the outside of your house can withstand an intense rainstorm. Still, pressure washing them can force water into crevices and cracks that can cause extensive damage and costly repairs.

Air conditioners

The intense flow of water coming from a pressure washer can crush or bend delicate air conditioner fins and restrict airflow, shortening the life of your air conditioning unit. Instead, try using a shop vac and a much gentler water flow device to rinse away debris inside your air conditioner after straightening the cooling fins.

Wood siding

Wood siding does have the potential to be pressure washed successfully, but there is also a risk of water getting under the exterior surface. When pressures are set too high, water can easily damage insulation, make contact with electric wiring components, and cause the possibility of mold growth. It's also essential to use care when pressure washing vinyl and aluminum siding so that the pressure does not bend or break siding pieces.

Old brick and mortar

Pressure washing old weathered brick houses and other landscaping surfaces with mortar can wear away any loose material and cause extremely costly damage to repair. Therefore, it is often best to use other methods when cleaning older brick-and-mortar surfaces.

Lead paint

Because of its hazardous potential, lead paint should be carefully contained when removed and should never be blasted into the air and onto surrounding surfaces by using a pressure washer.

Painted surfaces you aren't stripping

The powerful water stream coming from a pressure washer can easily chip paint off most surfaces. This makes it essential only to use low-pressure water flow to clean painted items like porch floors or painted outdoor furniture.

Living things

Though this one should be obvious, pressure washing is never a good choice for cleaning plants, pets, or other humans. The sheer force of water from a pressure washer can penetrate the skin and cause physical harm to your plants and animals.


Pressure washing windows is a bad idea. High-pressure flow can cause them to break, leading to expensive window replacement you had not planned for.

Light fixtures

Outdoor light fixtures can often withstand heavy rain and other weather elements, but you should never use pressure washing equipment for these fixtures. The high pressure can force water into cracks and cause extensive damage and safety risks.

Stained wood surfaces

Pressure washing is not the best tool for cleaning stained wood unless you plan to strip the stain from your deck. Pressure washing is known for stripping the stain off of wooden surfaces and will force you to restain those surfaces to protect them when misused.


Minor dents and chips in paint are likely to occur when using high-pressure water to clean a vehicle. These damages can leave a car vulnerable to rust. If you use a pressure washer to wash a vehicle, it should always be set on the lowest setting. Remember never to use a pressure washer underneath the hood. Doing so could force water into any crevices and cracks in the vehicle's engine and cause severe damage and extensive repair costs in the future.


Gutters can withstand intense storms and other weather elements, but the extreme power of a pressure washer can damage your gutters in the process. Though it is tempting to make your gutter cleaning quick work by using a pressure washer inside the gutters, it is best to remove debris by hand and use low-flow water sources to rinse the inside clean.

On the other hand, there are things around the house that can be safely pressure-washed. The pressure washer is an undeniably powerful tool that can help remove built-up algae and dirt from a home’s exterior and other outdoor surfaces. Reading instructions for the pressure washer and using the appropriate nozzle are essential parts of the pressure washing process. Here are some things that you can pressure wash:

Vinyl siding

Dirty and discolored vinyl siding can be pressure washed for cleaning. However, it is imperative to adjust the water pressure to a lower setting so that damaging your siding isn't possible.

Garage floors

Garage floors often have spots from dirt and oil stains that have built up over the years. Washing a garage floor using a low-pressure setting to apply a degreasing solution can help to keep your floors clean and free of future damages. After allowing the degreasing solution to sit for a while, you can switch to a higher setting and rinse it off.


As the years pass, wood or vinyl fences can collect algae, mud, and mildew. Homeowners working on spring cleanup or putting their house on the market often use pressure washers to take years off their fence’s appearance. It's important to use lower settings for softer woods to avoid damage and splintering. Vinyl and hardwoods can handle a heavier pressure load. It is vital to keep your vinyl or wood fence attractive and improve its curb appeal.

Garbage cans

Lots of stinky smelly debris can build up in the bottom of garbage cans. Though cleaning the inside of garbage cans is often not a fun job, you can make quick work of it by using a pressure washer with a scrub attachment at a lower setting to apply a cleaning solution and then rinse it away.

Porches and decks

Pressure washing can bring porches and decks back to life after debris, dirt, and dust have diminished their beauty. However, it is necessary to use lower settings to avoid harming the surfaces of your porches and decks.

Outdoor furniture

Outdoor furniture that isn't stored away during the winter can end up looking less than ideal. It's easy to renew the look of patio furniture by pressure washing at a low setting and testing an inconspicuous area to ensure that you don't damage surfaces. Pressure washing is best done on plastic or acrylic furniture and should only be done by a professional on your wooden patio furniture.

Garden paths

Once beautiful garden paths can collect dirt, algae, and moss and look a little rough. Be sure to protect nearby plants with tarps or other plastic coverings to ensure that you do not cause them damage when spraying off your dirty garden path.
