Can I pressure wash my deck?

Yes! In fact it’s an important component of a deck maintenance routine and should be done once a year. It is also recommended before staining or sealing. Using a pressure washer is not a trivial matter though. If you’re not comfortable with the machinery get a pro to do it for you.

Pros of Pressure Washing Your Deck

Efficient Cleaning:
Pressure washing can quickly and effectively remove built-up dirt, debris, and stains from the surface of your deck, saving you time and effort compared to manual scrubbing.

Restores Appearance:
Over time, decks can become discolored and dingy due to exposure to the elements. Pressure washing can help restore the natural beauty of the wood, making your deck look fresh and inviting again.

Prepares for Staining or Sealing:
If you plan to stain or seal your deck, pressure washing can help prepare the surface by removing any existing finishes, dirt, or contaminants, ensuring better adhesion and longevity of the new coating.

Environmentally Friendly:
Pressure washing uses water and does not require harsh chemicals, making it a relatively eco-friendly cleaning option compared to certain chemical cleaners.

Accessories like railings and benches can be cleaned at the same time.

Best Practices for Pressure Washing Your Deck

Use the Right Equipment:
Choose a pressure washer with an appropriate psi (pounds per square inch) rating for deck cleaning, typically between 1,500 and 2,500 psi. Use a wide-angle nozzle or a fan tip to disperse the spray evenly and reduce the risk of damage.

Test in an Inconspicuous Area:
Before pressure washing the entire deck, test a small, inconspicuous area to ensure that the pressure and technique are appropriate and do not cause damage to the wood or cellular PVC.

Maintain a Safe Distance:
Hold the pressure washer wand at least 12 to 18 inches away from the surface of the deck and maintain a consistent distance to prevent gouging or splintering the wood.

Work in Sections:
Divide the deck into smaller sections and work systematically, moving the wand in smooth, overlapping strokes to ensure thorough cleaning without overworking any one area.

Allow for Drying Time:
If you’re staining or sealing, allow the deck to dry completely before doing so. Depending on weather conditions, this may take anywhere from a few hours to a couple of days.
