Concrete and Asphalt
Concrete and asphalt surfaces are abundant in townhome communities. They are found usually in high traffic areas, which could mean a lot of accumulated dirt, dust, oil, grease, mold, mildew, and other buildups. Pressure washing is effective in blasting away all these unwanted substances. First, apply a detergent or degreaser onto the concrete surface. Allow the cleaning solution to sit for a few minutes. Then, rinse off the solution using a pressure washer with 2,500-3,000 PSI. After drying, apply a sealant to protect the surface from further damage.
Vinyl siding is a popular material for townhome communities as it is both durable and beautiful. Over time, these surfaces can develop mold, algae, and rust stains, as well as have fading and oxidation. To clean vinyl siding, use a soap dispenser to spray a bleach-based detergent onto the surface. Let the solution sit for 5-10 minutes. Then, rinse off the solution with a pressure washer. Use a pressure level of 1,300 to 1,600 PSI.
Wood surfaces are more delicate and thus, require a more gentle cleaning approach like soft washing. First, apply a wood deck cleaner onto the surface. Use a cleaner with mildewcide when dealing with mold and mildew overgrowth. Allow the solution to sit for a few minutes. Use a rotating scrub brush to loosen all the buildup. Then, rinse off the solution. Keep the pressure level at 500 to 600 PSI to prevent damaging the wood surface.
