Silt, leaves and grit vacuumed out rather than pushed along, the run jetted clean, and water taken away from your doorway, driveway and yard instead of standing on it.

Gullies, yard drains and channel drains, the linear gratings across a driveway or garage threshold, are the parts of a drainage system that catch everything before it reaches the pipework. That is their job, and it is also why they need clearing. Leaves, grit washed off tarmac, moss, sand from block paving joints and silt from garden beds all settle in the trap and the run below.
Once a gully trap fills with silt, the water level in it rises and it stops holding a water seal. The immediate result is smell. The next result is standing water, because the trap has no capacity left to pass the volume arriving during heavy rain. Channel drains fail the same way but faster, because their sump is shallow and they sit exactly where the most debris lands.
We clear gullies and channel runs properly: gratings lifted, the pot or sump wet vacuumed out down to the base, the outgoing run jetted clean, and the whole thing tested with water before it is reassembled. Everything removed leaves with us. Where a run keeps silting up despite that, a camera goes down to establish whether the fall has been lost or a section is holding water.
Surface water that cannot get into the drainage system does not disappear. It follows the fall of the hard surface, and on most properties that fall leads towards the building, which is exactly why gullies and channel drains were installed at the threshold in the first place. Once they stop taking water, the threshold becomes the low point.
The damage is slow and then sudden. Water sits against the base of a wall, tracks through into a garage or across a doorway during heavy rain, and saturates the ground beneath paving until the sub-base moves and the surface starts to dip and crack. Every winter freeze in that saturated ground makes it worse.
Garages, thresholds and airbricks are where surface water gets in. A blocked channel drain across a garage entrance means the first serious rainfall floods the floor.
Standing water held against brickwork saturates it and bridges damp-proofing, producing internal damp that gets blamed on everything except the drain outside.
Saturated ground under block paving or tarmac loses its bearing. Surfaces dip, joints open, and the repair is resurfacing rather than drainage.
A gully trap silted past its water seal loses the barrier between the pipework and open air. That means drain odours around the property and easier access for rodents.
A gully full of silt eventually passes it downstream, and silt accumulating in the below-ground run is how a surface water blockage becomes a full drainage job.
Gratings and covers lifted across the affected area, the drainage layout established, and it is confirmed whether the fault is at the gully or further along the run.
Where a run has been silting repeatedly, the CCTV camera goes down to check the fall and look for ponding, a displaced joint or a partial collapse holding material back.
The pot, sump or channel is vacuumed out down to the base, silt, grit, leaves and standing water removed, not stirred and pushed onwards.
The run leaving the gully is jetted to scour silt and root growth out of the pipe wall, so the capacity taken out is the capacity restored.
Water is run through the gully or the full length of the channel and watched away, so a partial restriction cannot hide behind an empty grating.
Gratings cleaned and reseated, surfaces washed down, and all waste taken away by us, with a note of anything worth keeping an eye on.
Water leaves the driveway, yard or threshold during rainfall rather than standing on it for hours afterwards.
A gully cleared to the base holds its water seal again, which is what stops drain odour around the property.
Wet vacuuming takes the silt away in house. Nothing is flushed downstream to become next season's blockage in the main run.
Clearing the pot is half the job. Jetting the outgoing pipe is what restores the actual capacity of the system.
Working surface water drainage is one of the cheapest defences a property has against damp, garage flooding and paving failure.
If the camera shows the fall has gone or a section has collapsed, repair, relining and excavation are all handled by the same people.
Surface water fittings vary widely across Hampshire property, and each type fails in its own way.
The traditional round gully with a water-sealed trap beneath the grating, taking rainwater downpipes and often kitchen or appliance waste. The pot collects silt below the outlet by design, which is what protects the run, but only until it fills. Clearing means vacuuming the pot to its base, not skimming the top.
Common where a downpipe connects below ground level or a yard needs a large-capacity inlet. They handle more volume and therefore more grit, and they are usually in the part of the property where debris collects.
Slot or grated channel across a driveway, garage entrance or commercial threshold, running to a sump or outlet at one end. Shallow by construction, so it silts quickly, and the sump is where everything ends up. Regular clearing is the difference between a working threshold and a flooded garage.
Modern developments in Whiteley, Hedge End and similar areas rely heavily on linear channel drainage for driveway run-off. The gratings are easily lifted for maintenance, but often never have been, and the sumps under them are where the entire problem sits.
Larger sites bring multiple gullies, long channel runs and often an interceptor before the outfall. These need scheduled clearance, because the failure mode is a flooded car park during trading hours rather than a slow inconvenience.
The four things that fill surface water drainage in Hampshire. Block paving joints shed sand continually, mature trees drop for two months a year, and moss lifts off roofs during every heavy shower. All of it ends up in the same place.
Where a gully silts up again within weeks of clearing, the outgoing run is usually holding water. That comes from a sagging section, a displaced joint or ground movement, and the camera identifies which before any repair is proposed.
Many Hampshire properties discharge surface water to a soakaway rather than a sewer. A saturated or silted soakaway makes every gully upstream of it appear blocked even when the pipework is clear, so establishing the outfall is part of diagnosing a persistent problem.

It depends on how many gullies or how much channel run is involved and whether the outgoing pipework also needs jetting. You are told what is involved before work starts, and nothing is priced on a guess.
It depends on the site. A driveway with mature trees or a commercial yard collects far more than a small enclosed patio. Once a year suits many properties, ideally after autumn leaf fall; busy commercial hardstanding usually needs more.
Because clearing the visible debris is only half of it. If the pot is silted below the outlet or the run leaving it is partly blocked, the capacity is still gone. Vacuuming the pot to the base and jetting the outfall is what actually restores it.
Usually a gully trap that has silted up past its water seal, so there is no longer a barrier between the pipework and open air. Clearing the pot properly restores the seal and the smell goes with it.
Yes. Gratings are lifted, the full length and its sump vacuumed out, the outlet jetted and the run tested with water before everything is reseated.
Not always. It can be a silted gully, a blocked run, a lost fall in the pipework, or a soakaway that is saturated or has failed. That is why the run is checked rather than just the grating.
Yes. Wet vacuuming and waste removal are done in house, so everything taken out leaves with us rather than going into the next chamber.
Yes: commercial hardstanding, delivery areas, car parks and estate drainage across Southampton, Romsey and the surrounding towns, planned around trading hours where the situation allows.
It can be. If water is heading for a garage or a doorway during heavy rain, ring; the phone is answered 24 hours a day, seven days a week.
Cracked channel, broken gratings, failed sumps and collapsed outgoing runs are all repairable, and that work is carried out by the same firm rather than passed on to somebody else.
