Clark County’s wet weather is hard on siding. Algae and mildew leave behind a green film, while shaded areas under eaves, decks, and porches can develop dark streaks that make the whole exterior look dingy. We use a soft wash process with low pressure and a cleaning solution that kills the growth at the source, followed by a gentle rinse. Your siding gets clean without blasting water behind the panels, stripping paint, or damaging the surface.
We clean vinyl, painted wood, and fiber cement siding along with trim, soffits, porches, and the underside of decks. Our house washing service is available throughout Vancouver, Camas, Washougal, Battle Ground, Ridgefield, and the rest of Clark County. And if the roof or gutters are due for cleaning too, we can take care of the entire exterior in one visit. Every job starts with a free estimate.




Algae and mildew do more than make siding look dirty. They hold moisture against the surface, which can wear down paint, leave stubborn stains on vinyl, and give rot a place to start around wood trim. Shaded areas usually show it first. North-facing walls, areas under trees, and siding beneath decks can turn green surprisingly fast in Clark County’s wet climate.
Regular house washing removes that buildup before it gets established. It’s also a smart first step before painting, since new paint needs a clean surface to bond properly, and before selling a home, when the exterior is one of the first things buyers see in photos. The siding in this before-and-after wasn’t damaged or worn out. It was simply covered in years of buildup, and one soft wash brought the original finish back.
Before we start, we protect outlets, light fixtures, and other sensitive areas, then wet down nearby plants and landscaping. From there, we soft wash the siding from bottom to top, treating each side of the house completely. Upper stories, dormers, and gable peaks get the same attention as the first floor, so the entire exterior is cleaned evenly.
Trim, soffits, and fascia boards along the roofline are included in the wash. If the outside of your gutters has dark streaking, we can brighten those during the same visit as well. Once the cleaning is finished, we rinse the siding, windows, walkways, and surrounding areas so there’s no leftover solution or overspray. If the roof or gutters need cleaning too, we can handle the whole exterior in one appointment.

Awesome roof cleaning company! My husband and I were having a party and wanted to try to get our deck awning cleaned in time for the party. Jessa and Zach worked together to squeeze us in and Zach did a fantastic job! Both were friendly and professional every step of the way, and we will definitely utilize their services again!Posted on Google![]()

Clark County Roof Cleaning is excellent on their cleaning service. They were on schedule from the beginning of the scheduling of estimate to service confirmation, and project executions. The coordination and communication from Jessa of the office were so precise without any confusion. I had soft washing for moss removal and power wash for my driveway. Ian of the company did an excellent job for me. I have been very pleased and satisfied with their services from the beginning to the Job completion, and would recommend Clark County Cleaning to anyone who needs the service. I rate Clark County Roof Cleaning service 5 out of 5.Posted on Google![]()

How often your house needs washing depends mostly on shade, moisture, and tree cover. A home that gets plenty of sun may stay clean for quite a while, while one tucked under fir trees or with a north-facing side that stays damp will show algae and mildew much sooner. A good rule of thumb is simple: if you can see green film or dark streaks from the street, the buildup is already well established.
During the free estimate, we’ll look at the condition of the siding and tell you what makes sense for your home. Many customers have the house washed at the same time as their roof and gutters, which makes it easier to keep the whole exterior on one maintenance schedule.
