How to Pressure Wash a House in 10 Easy steps

When it is time to pressure wash a house, important steps should be taken to ensure you do not incur any damages.

1. Improper use of pressure washers or selection of the wrong spray tip can cause:

– Shredding of window screens
– Paint removal
– Vinyl siding to be ripped off or loosened
– Window seals to break
– Water damage inside your home
– Cracks in brick or stucco siding
Remember, when choosing a pressure washer, PSI is the pressure output measured in ‘pounds per square inch’ and GPM is the volume of water a machine delivers, measured in ‘gallons per minute’.

2. Choose the right pressure washer:

If you are cleaning wood or aluminum siding, a different pressure and spray nozzle are needed than what is typically used for vinyl siding.

3. Protect plants, shrubs, electrical and light fixtures from water pressure and water seepage:

Cover all with plastic or waterproof drop cloths and seal covers with waterproof tape.

4. Avoid all vent openings:

Cover all openings with plastic and tape to avoid water damage in your home.

5. Close all windows:

Remember to check every floor and every room.

6. Prepare the power washer cleaning solution:

Be sure to use the right amount of solution and water when filling the machine.

7. Connect the garden hose to the pressure washer water supply:

Turn on the water.

8. Test the pressure washer:

Hold the nozzle with both hands at least 3 feet away from the wall and move in only if necessary to increase the pressure required to remove dirt.

9. Always start at the top of the house:

Spray overhangs and gutters. Then move the spray from side to side all the way down.

10. Rinse:

Use only water for rinsing and rinse from the top down.
