Patio and walkway cleaning in Gresham, OR removes the slippery moss, algae, and embedded dirt that build up on concrete, pavers, and natural stone in the wet Pacific Northwest climate. Most residential patios in the 97030 area can be cleaned in one to two hours. A flat price is quoted before work begins.
Concrete and paver patios in Gresham stay damp from October through May, which is long enough for moss and algae to establish a thick layer over the whole surface. The growth makes patios and back walkways genuinely slippery and a fall risk. Homes in the Pleasant Valley and Centennial areas with patio space under large trees deal with this every year. Pressure washing removes the growth down to the surface and leaves the texture that provides grip again.
Concrete pavers, brick, bluestone, and slate all require a lower pressure setting than plain poured concrete. The mortar or sand joints between pavers can be displaced by a high-pressure wand aimed into the gaps. A surface cleaner or low- angle fan tip cleans the face of the paver without eroding the joints. After cleaning, a sand re-fill of the joints is sometimes needed, depending on the original joint depth and how long the pavers have been in place.
Concrete steps and walkways see heavy foot traffic and accumulate the same algae and moss growth as patios, but in narrower passes that a surface cleaner attachment cannot always reach efficiently. A wand with a turbo tip cleans step risers, railings bases, and narrow side walkways without the run-off pattern that a wide surface cleaner leaves. Steps leading to a front door on a shaded north-facing house are among the most commonly requested spots in Gresham because the growth comes back quickly and is the first thing guests see.
$75 to $200
A standard residential patio runs $75 to $150 in Gresham. Larger patios or ones that include steps, a side walkway, or pavers that need careful joint protection run $150 to $200 or a bit more. Adding the driveway at the same visit is often more cost-effective than scheduling separately.
Yes, with the right technique. The nozzle angle and pressure setting are both adjusted to stay below the level that blows sand out of the joints. Some sand loss is possible on joints that are already low, and re-sanding those areas after cleaning is a straightforward fix.
Pressure washing removes the moss growing on the surface and in shallow cracks. Deep cracks with established root growth may need a scrub brush or a moss-kill treatment in addition to the wash. The technician can identify these spots during the job and recommend the right follow-up.
Once a year in early spring is the most common schedule for Gresham patios. The winter rain season promotes the most growth, so a spring cleaning restores safe footing before the outdoor season. Patios under heavy tree cover may need a second clean in fall to remove leaf stain before winter sets in again.
