Why Choose WOW Gutters Ltd for Gutter Cleaning
Green or black stains on your walls below the gutter line are caused by overflow water depositing algae and organic matter. WOW Gutters Ltd stops the overflow and cleans the staining. Call 07421 433910.
Green, black, or brown vertical streaks below the gutter line are a clear sign of gutter overflow. When water spills from a blocked gutter, it carries algae spores, moss fragments, and organic matter from inside the channel down the wall. These deposits stain the brickwork, render, or stone, and the persistent moisture encourages algae growth directly on the wall surface.

Why Green Stains Appear Below Gutters
Green, black, or brown vertical streaks below the gutter line are a clear sign of gutter overflow. When water spills from a blocked gutter, it carries algae spores, moss fragments, and organic matter from inside the channel down the wall. These deposits stain the brickwork, render, or stone, and the persistent moisture encourages algae growth directly on the wall surface.
- Overflow water carries algae and organic matter from inside the gutter
- Repeated overflow creates permanent green or black vertical streaks
- Algae grows on the persistently damp wall surface below the overflow point
- Staining is most visible on light-coloured render and brickwork
- Mortar joints absorb the staining and are difficult to clean fully
- Left untreated, staining becomes deeply embedded and hard to remove
How to Remove Green Stains and Stop Them Returning
Removing existing stains and preventing new ones requires two steps — fixing the gutter blockage that causes the overflow, and cleaning the staining from the wall surface.
- Clear the gutter blockage to stop further overflow
- Repair any damaged joints, sagging sections, or bracket failures
- Clean wall staining using appropriate methods for your wall type
- Light staining on UPVC or smooth render can be pressure washed
- Deep staining on brickwork may need specialist cleaning products
- Install gutter guards to prevent future blockages and overflow

FAQs — Green Stains on Wall From Gutter
Can't find your answer? Call 07421 433910.
What causes green stains on walls below gutters?
Green stains are caused by algae and organic matter deposited on the wall by overflow from a blocked or leaking gutter. The moisture keeps the wall damp, allowing algae to grow directly on the surface.
Can green stains be removed from brickwork?
Yes — light staining can be pressure washed off. Deep staining on porous brickwork may need specialist cleaning products or multiple treatments. Preventing further overflow is essential for a lasting result.
Will the green stains come back after cleaning?
They will return unless the gutter problem is fixed. WOW Gutters Ltd addresses both the cause (the blocked gutter) and the symptom (the wall staining) for a complete solution.
How much does it cost to clean green stains off walls?
Wall stain removal costs from £60 depending on the wall area and the severity of the staining. Combined with gutter cleaning, the total cost depends on your property size.
Can green stains damage my walls?
Yes — algae growth holds moisture against the wall surface, which can penetrate porous brickwork and cause internal damp over time. The staining also makes the property look neglected.
