House washing removes algae, mold, pollen film and grime from siding and trim using a method matched to the material. In Barrington, IL, walls range from century-old painted wood to vinyl and brick. Rob, the family-business owner at Rob's Exterior Services, does it himself with no subcontractors. He names a price after a photo of the home reaches him. Text (815) 451-0106 to start.
Look at a house in Barrington and the first question is what it is made of. Wood clapboard painted a dozen times, vinyl added in the eighties, fiber-cement planks from a more recent remodel, a brick front with wood gables: each wall behaves differently when wet, and each reacts to cleaning in its own way.
That is why house washing here cannot be a single procedure. Rob reads the house first and picks the method to suit. Price follows from that reading rather than preceding it, which is why a photo comes before any number. This page explains what he looks for and how the work differs from wall to wall.
What is on your wall: a siding-by-siding guide
Painted wood is common in the Historic District, where most houses were built between 1860 and 1930, and it needs low pressure and attention to paint condition. Vinyl is forgiving but can chalk and has gaps that should not be flooded. Aluminum cleans easily but dents. Fiber-cement is sturdy but its finish can wear. Brick and stone need testing, since old mortar is vulnerable.
When the material is unclear, a photo is enough. A close shot of a corner or a seam usually tells him. Many homes have mixed materials, such as brick on the first floor and siding above, or stone accents, and those need a combined approach. He will explain what he plans for each.
- Painted wood: low pressure, check paint first
- Vinyl: gentle rinse, avoid flooding seams
- Aluminum: easy to clean, avoid hard spray that dents
- Fiber cement: low pressure, watch seams
- Brick and stone: test first, protect mortar
Why the north wall turns green first
Algae and mold settle in where walls stay damp, and north-facing and shaded sides dry slowest. Barrington's mature trees extend that shade across many walls, so the pattern is common. The green often starts at the base, where splash from rain and moisture from soil keep the siding wet.
Left alone, the film spreads and holds moisture against paint and caulk. Washing it away helps the wall dry. The siding mold guide explains the biology and the limits of washing. Rob will also tell you if growth is a symptom of a larger moisture problem, such as a leaking gutter, which is worth fixing.
Common mistakes homeowners make washing their own siding
Renting a pressure washer is the classic one. High pressure can force water behind siding, strip paint, gouge wood and blow out caulk around windows. Water behind the wall does not dry quickly and can lead to mold inside. It is easy to cause damage that is invisible for months.
Another mistake is working top to bottom unevenly or letting cleaner dry on the wall, which leaves streaks. And many people skip rinsing plants. Rob avoids these by working in sections, rinsing thoroughly and protecting landscaping. For a side-by-side, see the soft wash and pressure wash comparison.
When the paint or caulk needs attention before washing
Clean siding shows every flaw. Peeling paint, open seams and cracked caulk around windows are more obvious once the grime is gone. For some houses, the right order is repair, then wash. For others, wash first so a painter can see the real surface.
Rob will tell you which applies. If a wall has bare wood, he may recommend painting soon after washing to protect it. He does not handle painting or carpentry, so he will point you toward the right trade for that. His work is cleaning the surface well and telling you what he sees.
What the day looks like at a Barrington house
Rob arrives, walks the house and confirms the plan. Windows are checked, plants are wetted, and any loose items are moved. The cleaning solution is applied at low pressure in sections, left to work, and rinsed from the top down. Trim, porches and eaves get their own attention.
After the rinse, he checks for missed spots and streaks. Some stains, like rust or old overspray, may remain, and he points those out. The house will often look noticeably cleaner as soon as it dries, and the film that builds up on the walls gradually returns more slowly in sunny spots.
Getting a quote when the house is thirty miles away
Rob comes out from Woodstock, around thirty miles away, and plans a full visit for a wash. House washing is a full-visit job, and it combines well with window cleaning and gutter cleaning.

House Washing through the year in Barrington
Spring
A common time for house washing. Winter grime and the first algae come off, and the wall dries well in rising sun.
Summer
Warm and dry suits washing. Shaded walls grow green fast in humid stretches, so summer is a useful touch-up window.
Early fall
Get it done ahead of leaf drop and cold snaps, so walls dry out and the house enters winter clean.
Winter
No washing until it warms up. Look over the walls for peeling paint, cracked caulk and damp patches while planning spring.

A house tells you when it needs washing; the north wall goes green and the trim goes dull. Text Rob photos of your Barrington house at (815) 451-0106, one for each side, and tell him what the siding is if you know. He will answer with a plan and a price, and he will be the one at the door.
