Pressure washing on the property can be an excellent way to give the exterior a new life, from clearing away built-up dirt or roof moss removal and mildew growth to eliminating mildew growth.
But not every surface can withstand high-pressure washing techniques; using improper techniques could result in property damage instead of an effective exterior cleaning.
Safe Surfaces for Pressure Washing
Not all materials are suitable for pressure washing, but several surfaces can withstand it safely—such as:
Concrete Surfaces
Surfaces built with concrete, such as driveways, sidewalks, and patios, are well-suited for pressure washing. Over time, they collect oil stains, dirt, and mildew. Regular pressure washing helps restore a fresher appearance and enhances your property’s curb appeal.
Vinyl Siding
Pressure washing vinyl siding is generally safe when handled by professionals. They use a low-pressure setting and a wide-angle nozzle to prevent water from getting underneath the panels. This technique is also used in commercial pressure washing in Modesto to remove cobwebs, dust, roof moss, and algae buildup.
Where to Avoid Pressure Washing
Surfaces that need to be handled by professionals are:
Wood Siding and Decks
Wooden surfaces are too fragile for pressure washing, as excessive force can cause splintering or remove their finish, resulting in permanent marks. It’s advisable to use a professional pressure washing service to avoid long-term damage to your property.
Roof Shingles
Cleaning roof shingles might seem like a quick and easy option, but using a pressure washing method on them can damage their protective coating, causing it to loosen. Instead, experts recommend using a gentle cleaning solution for power washing, as soft washing is safer and yields better results.
