Vinyl sidingThe siding of your home in Portland is exposed to weather and environmental elements day after day and year after year. Just like other areas of the house that need regular maintenance, the siding requires some attention in order to keep it looking its best. No matter what material the siding of your home is made out of, our team of experts has the experience, equipment, and technique necessary to bring it back to life.

Dust, pollen, dirt, mildew, and mold tend to accumulate on the siding of home which can negative impact the aesthetics of the home’s exterior. Years of buildup can even alter the color of siding resulting in a dark, grimy, and unsightly appearance. Restoring the siding back its original state should be handled by professionals as siding can be easily damaged by excessive water pressure.


Cedar, vinyl and aluminum siding are best cleaned by a technique known as softwashing due to their delicate nature. Softwashing is the process of using effective cleaning solutions combined with lower pressure and cold water to remove stains and dirt from siding.

Typical power washing uses high pressure and high temperature water to lift stains but this can severely damage siding. Vinyl is one of the most popular types of siding but it can crack under high pressure. Aluminum is another commonly used material for siding but it is susceptible to dents under pressure. Cedar wood is a beautiful choice for siding but some pressure washers are powerful enough to cut right through it.
