Home›Gutter Clearing›St John’s
Rain pouring off the eaves in a curtain, a downpipe that has gone silent, grass waving from the roofline: we sort out badly blocked gutters across St John’s, digging out whatever is causing the jam and proving the water flows again.
Overflowing guttering is rarely about the whole run. Nine times out of ten there is a single plug, perhaps a wad of oak leaves at an outlet, a tennis ball wedged in a swan neck or a clump of rotted seed and moss forming a dam halfway along. Our gutter clearing St John’s service hunts down that plug, breaks it apart and removes it, then deals with the silt and sludge that has backed up behind it, so the system works as designed rather than just looking emptier.
Gutters that have gone untouched for years can be startlingly full. We regularly lift out soil deep enough to support grass, ferns and sycamore seedlings, along with roots that have woven themselves through the debris. That material is loosened by hand, the loose sludge sucked away by our high-power vacuum, and then the downpipes are tackled from the base with rods and water until they run clear. Mesh and foam guards are removed, cleaned beneath and slotted back. The visit ends with a hose test, so you know the next downpour will go down the pipe rather than over the edge.

Most of the badly blocked gutters we meet in St John’s sit under oaks. Oak leaves are tough and leathery, they curl as they dry, and they lock together around outlets in a way softer leaves do not. Add acorn cups, catkins and twigs and you have a solid barrier within a couple of autumns. Homes overlooking St John’s Lye and those on the wooded roads climbing towards Hook Heath take the brunt of it, while pines on the larger plots add a mat of needles that knits everything together.
The village’s older properties are particularly vulnerable. Victorian and Edwardian cottages near the church and canal often have narrow cast-iron or early plastic downpipes with tight offsets where debris catches easily, and their hoppers can fill to the brim without anyone noticing. On later semis and detached homes, it is usually the corners above bay windows and porches that block first, as water and leaves funnel into them from two directions.
Weather plays its part too. When an autumn storm sweeps through Woking, a gutter that was coping can overflow overnight, and the moist air along the Basingstoke Canal keeps moss growing on nearby roofs, sending more material into the channels after every heavy shower. Our rods reach to ground level; whenever the trouble continues into a buried drain or gully, we will show you where and suggest calling a drainage specialist. We work throughout GU21 in St John’s and the surrounding streets.
We follow the water backwards from wherever it is escaping until we find the true cause.
Starting from the drip line or staining on the wall, we inspect outlets, hoppers and downpipe joints to pinpoint exactly where the water is being stopped.
Packed leaves, soil and rooted plants are broken apart by hand and lifted out whole, so nothing is pushed deeper into the outlet or pipe.
Once the main plug is gone, the sludge that has backed up along the gutter is drawn out with our vacuum, leaving the channel clean and shallow again.
Downpipes are rodded and flushed from ground level until water runs straight into the gully, and a final hose test confirms the overflow has stopped.

A routine clean is fine for gutters that are simply a bit full. Clearing is the right call in situations like these:
Blocked gutters carrying wet soil are heavy, and that weight bends brackets over time. Getting them cleared quickly protects the gutter itself as well as the walls and fascias around it, and it removes the damp conditions that let moss and algae spread down the brickwork.
Because blocked gutters vary so much, we price each job individually, considering:
A photo of the overflow and one of the whole elevation are usually enough for us to confirm a fixed price on the day you send them.
Cleaning is planned maintenance before problems start. Clearing is what we do when the gutter has already blocked and is overflowing, which often means digging out compacted material, removing plants and rodding downpipes. It involves more investigation, because we need to find the precise point where the water is being held back.
Oak trees are the main reason. Their leaves are thick and slow to rot, and they curl and lock together around outlets. Combined with acorn cups and twigs, they form a firm plug that ordinary rainfall cannot shift, which is why homes beside the common and the wooded roads often need clearing.
Usually, yes. We push rods up from the shoe and flush with water, working through bends, offsets and hoppers until it drains freely. Should the jam lie beneath the ground in the drain itself, we point out where so a drainage company can take that section on.
We will, roots included. Pulling off just the visible leaves leaves the root mat behind, and the plant comes straight back. We lift the whole clump with the soil around it and then vacuum the channel clean so nothing is left to regrow.
Guards stop larger leaves but finer material such as seeds, needles and grit still passes through and builds up underneath. Eventually the channel fills and water runs over the top. We lift each guard out, scoop and vacuum the trough below, rinse the guard and clip it back.
We always try to fit urgent overflows in as soon as possible, as water pouring down a wall can cause damp in a matter of days. Send us a photo or short video and your address, and we will offer the earliest slot available.
