Why clean your siding
Beyond looks, clean siding lets you see its real condition: warped boards, open joints, peeling paint or areas that stay damp. It’s often the moment to spot maintenance before it becomes a bigger job.
North-facing walls and those next to trees or hedges turn green faster. Facades along a busy street tend to get a grey film instead.
A method matched to the material
Vinyl and aluminum usually handle a low-pressure wash with a gentle cleaner. Wood, engineered wood and painted surfaces need more care, because excess pressure can raise the grain or lift paint. Fibre cement, brick and stone each have their own needs.

What to include
Name the siding if you know it, the number of storeys and which sides need cleaning: the whole house or just the wall that turns green. Mention obstacles like a deck, garden beds, a porch roof or a shared fence.
A photo of each side concerned is very helpful. If you don’t know the material, choose “I don’t know” and the professional will identify it.
Precautions and things to watch
Water should never be aimed upward under the laps or at outlets, light fixtures and vents. Close the windows and point out fragile areas. If your house is older and the paint is peeling, say so: older paint may contain lead and calls for a careful approach.
Matching based on availability
Your request is reviewed, then shown as an anonymous summary to selected professionals. Your contact details are shared only with your permission. The professional then confirms the method, price and date directly with you.
Frequently asked questions
Is pressure washing safe for vinyl siding?
With low pressure and the right technique, usually yes. Too much pressure, or spraying upward, can push water behind the panels. The professional adapts the method to the siding’s condition.
Will the green streaks come back?
On a shaded, damp wall, moss and algae eventually return over time. Trimming vegetation that sits too close and making sure water drains away helps slow it down.
Should siding be cleaned before painting?
Yes, it’s often recommended before a paint job. If you plan to repaint, mention it in your request, or submit an exterior painting request and note the cleaning you want.
Do I have to clean the whole house?
No. You can target a single side, such as the one turning green. Just specify which sides are included.
