Cleaning Siding on a House

Clean Your House / January 23, 2018

Turn on the pressure washer. As you begin to initiate the wand, avoid pointing up and refrain from directing the spray where the vinyl lengths overlap. If you stream water upwards or between the laps in siding, the water is likely to force behind the vinyl panels, penetrating the insulation. It is best to use a tall ladder when spraying. If water is trapped behind the siding, it doesn’t dry easily and leads to water damage. The same can be said when you target the spray into corners, be wary of how the water is impacting the crevices where the boards end. These areas will still get misted by off-spray as you clean surrounding areas, but plan to wipe them clean with a dry towel.

Use the soapy spray to cover the vinyl siding, keeping the tip of the wand at a 45-degree angle to the window and trim. Aiming the wand at that angle will help to lift and remove dirt from beneath more effectively than blasting it straight on.

You will find that the soap may run low every few minutes. Keep an eye on its level so that you can turn off the pressure washer and refill periodically as you make your way around the perimeter of your home. Use the depleted reservoir on as an opportunity to switch nozzle tips (refer to step 5) and rinse the area that you just applied soap to before the soap dries on the siding.
