Mildew and mold on siding make your home appear dirty, but they can also damage the physical surface over time. Pressure washing is a fast, effective way to clean this off. Using the proper technique and equipment, you can restore the appearance of your siding and protect your home from any developing damage.
Why Pressure Washing Works
A pressure washer applies water at high volume to blast away dirt, grime, and biological growths, such as mold and mildew. This differs from scrubbing by hand because pressure washing allows for the quick and efficient coverage of large areas, as well as reaching tight or hard-to-reach spots. Done correctly, it is safe for fiber cement, wood, vinyl, and other common siding materials.
Use the Right Equipment and Detergent
Professionals will start by picking a pressure washer rated for a range of 1,500 to 2,500 PSI for residential siding. They will select a 25- or 40-degree spray nozzle to achieve a wide, gentle spray that targets specific surfaces effectively. Mildew and mold require a cleaning solution formulated explicitly for siding, so those highly trained will look for one known for its mold-killing agents, such as vinegar or sodium hypochlorite (bleach), and will do their utmost to avoid using harsh chemicals that might damage landscaping or paint.
Pre-Treat the Affected Area
Pre-treating the area before blasting is a smart move. Professionals will generously spray the chosen cleaning solution, and then let it sit for five to 10 minutes so that the growth loosens up. This will reduce the level of pressure you need to use, minimizing the risk of damage to your siding.
Wash in a Controlled, Safe Manner
Those with proper training and experience will ensure that the spray wand is around 12 to 18 in. away from your siding and aim it slightly downward to prevent spraying water underneath the siding panels. They will use smooth, overlapping strokes that go from top to bottom and will be careful near trim, vents, and windows. Furthermore, professionals will always use eye protection and exercise caution on wet surfaces to prevent slipping.
Prevent Mold and Mildew From Returning
Mildew and mold thrive under damp, shaded conditions. Trim back shrubs and trees to improve airflow and sunlight, and clean your gutters routinely to prevent overflowing water. Consider an annual application of mildewcide treatment to slow down future growth.
When done with an effective technique, power washing empowers you to remove mildew and mold from your siding, allowing you to protect your investment and restore its curb appeal.
