When Do Gutters Actually Need Cleaning?

Nobody looks at their gutters. They sit above eye level, they work invisibly, and the first sign of trouble is usually a stain on a wall or a damp patch in an upstairs corner that gets blamed on something else entirely.

Clearing them is one of the cheapest jobs you can have done on a house, and the things it prevents are among the most expensive.

Water spilling over the front edge during heavy rain is the obvious one, and by then it has been blocked for a while. A dark vertical streak down the wall under a joint or a downpipe is the same message written more slowly.

Plants growing out of the gutter mean there is enough accumulated silt up there to support root systems, which is a lot. Sagging brackets mean the gutter is carrying standing weight it was not designed for.

Inside the house, damp in an upstairs corner or along the top of a wall is very often a gutter problem being treated as a wall problem.

Overflowing gutters soak the wall below them continuously through a wet season. On render, that means staining and eventually blown patches. On stonework and masonry, saturation and frost damage to the pointing. Either way, it is a far bigger job than the gutter ever was.

Persistently wet walls also drive internal damp, and that is where the money really goes: replastering, redecorating, and chasing a problem whose actual cause is sitting outside at roof level.

Water overflowing down the wall also lands at the base of the house rather than going into a drain, which does the driveway and patio below no favours either.

A house with no overhanging trees is usually fine on an annual clear, ideally in late autumn once the leaves are down. A house under or near trees wants twice a year, and it is not optional.

Roof moss changes the picture too. If the roof is shedding moss into the gutters, they will silt up regardless of how many trees are nearby, and the real fix is dealing with the roof rather than clearing the same downpipe every spring.

Clearing the visible debris is the easy half. The rest is flushing each downpipe through to confirm it actually runs, because a clear gutter feeding a blocked downpipe is still a blocked system, and the blockage is usually at the shoe or an underground bend where nobody can see it.

A proper job also means wiping the fascia down while the access is there, checking joints and brackets, and flagging anything that needs a repair rather than a clean. Our gutter cleaning includes the downpipe flush and the fascia wipe-down as part of the work, with before-and-after photos so you can see what came out.

The equipment is already up there, so soffit and fascia cleaning on the same visit costs far less than a separate one, and it is the single most transformative thing you can do to the front of a house for the money. Greyed, algae-streaked UPVC comes back to white and the whole roofline looks new.

For anything commercial, this is normally folded into a scheduled maintenance contract so nobody has to remember to book it.
