House washing cleans the exterior walls of a home, lifting algae, mold, dust, spider webs and grime with a low-pressure wash chosen for the siding. Rob runs a Woodstock family business without hired crews, and he washes houses in Johnsburg, IL, where older painted homes and newer vinyl sit side by side. House washing is quote-based: message (815) 451-0106 with a picture for a free quote.
Walk through Johnsburg and the siding tells you the decade. Smaller homes from the early to mid-1900s sit near the lake in places like East Johnsburg. Houses from the 1970s through the early 2000s fill much of the rest. Newer subdivisions such as Remington Grove add townhomes and two-stories in more recent materials. One village, many kinds of wall.
That variety is the reason a one-size house wash does not work. Painted wood, aluminum, vinyl and fiber cement each have their own limits, and the wrong method on the wrong siding costs real money. This page goes siding by siding, so you can see what Rob thinks about before he quotes your home.
Siding by siding: what each type tolerates
Vinyl is the most common and the most forgiving, but it can be damaged by hot water, scraping and high pressure that forces water up under the laps. It oxidizes over time, leaving a chalky film that cleaning improves. Aluminum dents easily and shows scratches. Fiber cement is durable but needs gentle handling around joints and paint.
Painted wood is the most delicate. Older paint can lift, and aged boards soak up water. On these homes, Rob uses the lightest effective method and takes extra care at joints and trim. He may also decline to wash a wall where peeling paint will come off in sheets, since a wash would expose the problem without solving it.
- Vinyl: gentle spray, rinsed top to bottom
- Aluminum: gentle, no scrubbing that scratches
- Fiber cement: careful at seams and painted edges
- Painted wood: lightest method, check paint first
Older lakefront cottages and what age adds
Older small homes near the water may have been remodeled in pieces, with several types of siding on one house, original window frames and caulk that has been painted over many times. Water that gets past an aging seal can wet the wall cavity, so Rob keeps spray angled downward and away from openings.
Many of these houses were built close to the shoreline, with plants, docks and sheds nearby. Rob looks at the surroundings before he starts, protecting vegetation and keeping runoff away from the water. If a house has several different surfaces, he sometimes treats each differently within the same visit.
Newer townhomes and tight lots
Newer developments have their own constraints. Townhomes share walls, lots are narrow, and neighbors are a few feet away. Overspray, parked cars and shared landscaping all matter. Rob plans his setup around those limits and talks with you about what to cover or move.
Many HOAs also have rules about exterior work and appearance, and some set expectations for when and how cleaning happens. The guide to HOA and 55-plus exterior cleaning is a good place to start if you live in a managed community. Check your own association's requirements before booking.
What the green is, and what it means for the wall
Green growth on siding is typically algae. Black speckling is often mold or mildew. Both thrive on moisture and a layer of organic grime, which is why damp lakeside walls and shaded north faces show them first. A wash removes the growth, but if the wall stays damp, it can return.
The guide to mold and algae on siding gives the full picture. A cleaner wall dries faster and shows damage sooner, which is good news. If Rob notices soft boards, cracked vinyl or failing caulk while he works, he will tell you so you can fix those before they cost more.
How Rob prices a house wash without a number on this page
House washing has no fixed price because houses differ. Height, siding type, amount of growth, trim detail, nearby plants and access all change the effort involved. Rob asks for a street view plus a couple of close-ups of the worst spots, then sends a quote. The quote is free.
A two-story home with many windows takes longer than a ranch with simple walls. A house with heavy algae needs more dwell time than one with light dust. If you are comparing, ask for what is included, such as trim, doors, soffits and the foundation line. Rob is clear about the scope of every quote. See also soft washing.
House Washing through the year in Johnsburg
Spring
The usual time to wash. Winter grime, pollen and algae that grew under snow come off before summer humidity encourages regrowth.
Summer
Fine for a targeted wash of shaded or lake-facing walls. Start early in the day on sunny sides so cleaner does not dry too fast.
Early fall
Ideal for a pre-winter wash and for sellers. Clean walls dry faster in the cooler months, and any problem areas are easier to spot.
Winter
Not a washing season outdoors. Use these months to photograph problem walls, plan a spring slot and note any peeling paint or loose siding.
