Is Power Washing Bad For Your House?

If you do not power wash your house in the right manner, power washing can be very destructive. This goes for other popular pressure washing surfaces like concrete or wood decks.

When pressure washing a house, plastics paint and other brittle materials could easily be damaged, scratched or completely removed.

The main function of a pressure washer is to push water through a small hole at the end of the hose, this creates immense pressure and the jet of water can indeed cut through certain materials.

To avoid damaging your property, you should stand at a distance that allows the water jet to lose some of that initial pressure.

If you have particular areas that are brittle, power washing should be avoided altogether.

Most pressure washers have a function that allows you to turn the nozzle to create a mist instead of a jet, this could be used on areas that are more fragile.

What Should I Spray My House With Before Pressure Washing?

The initial wash stage should be performed using a mildewcide and bleach mix.

Consult your models manual regarding the right mix, but a good rule is for every nine parts detergent use one part bleach.

If you have shrubbery, plants, or foliage in close proximity to your property you should take the proper steps to make sure these are sheltered from any back spray or overspray.

Use plastic sheeting and duct tape or tie-wraps. 

Why You Should Not Pressure Wash Your House

If you have any form of dashing (pebble, bottle, rock) then you should never pressure wash your home, the power of a pressure washer, even at a low psi, could dislodge the dashing.

You should also avoid pressure washing your home if it is made of hardwood as the high pressured water could penetrate the wood and cause severe structural damage.

Always make sure you’re using the right amount of pressure when dealing with different surfaces and materials.

What Time of Year Is Best to Power Wash Your House?

Typically, you should power wash your house between the months of March and November.

Obviously, if you live in a hot or cold climate you may need to adjust this but for the sake of this article, we will concentrate on the average weather cycles.

The winter months can be really bad for power washing because of the added hazards, ice forming, power washer failures, and underperforming detergent.

Not to mention the fact that power washing in the winter seems a little counter-productive due to the actual weather.

Taking this into account, power washing should be done in the spring/summer cycle. This cuts down on some major hurdles and allows the property to dry quicker.

What Is The Perfect Weather Condition to Power Wash Your House?

Most people believe that power washing your home needs to be done in sunny conditions, but this is actually wrong. When the sun is shining and there are no clouds in the sky power washing can be really difficult.

The best time to power wash a house is to do it on an overcast day, the diffused sunlight helps in finding dirty marks and streaks.

You should never perform any pressure washing during a thunderstorm, the large pressure washer hose is an excellent conductor for lightning.
