0800 Homefix clears blocked outside drains across London and the South East, from an overflowing gully or yard drain to a blocked inspection chamber or manhole. Our engineers use high-pressure water jetting and CCTV to clear the blockage completely and find what caused it, rather than just shifting it. Same day service is standard. There is no call out fee, you pay for the work, not the journey.

WHY US
An outside drain that has backed up or is overflowing in the garden, yard or driveway is more than an eyesore. Standing wastewater is a hygiene risk, it smells, and left alone the blockage moves further down the run and becomes harder to clear. Outdoor drains also tend to block for a reason, silt, leaves, root ingress or a fault in the pipe, so clearing it without finding the cause often means it blocks again.
That is how our outdoor drainage service, part of our full drainage service across London, is built. Our engineers arrive with high-pressure jetting and CCTV equipment on the van, so most external blockages are cleared on the first visit and, where a drain keeps blocking, we can see exactly what is happening underground. Same day service is standard, so an overflowing gully or manhole is usually dealt with the day you call. If the drain is overflowing toward the property or flooding the garden, that is an emergency, and we aim to reach you within the hour.
Outdoor Drains
Our engineers clear every kind of external drain across London. Here are the outdoor blockages we deal with most often.
01
Outside gullies collect silt, leaves, grease and garden debris until they overflow. We jet the gully and the run into the main drain so it flows freely again.
02
An overflowing chamber or manhole usually means a blockage in the main drain run. We clear it with jetting and can survey the run with CCTV to confirm the cause and location.
03
Channel and slot drains across driveways and patios block with grit and debris. We clear the channel and check it drains as it should, especially before winter.
04
Drains that overflow in heavy rain can be blocked, collapsed, or overwhelmed. CCTV confirms whether it is a blockage or a fault so the right work is carried out.
05
Tree and shrub roots find their way into older drain runs through joints and cracks. Where a drain keeps blocking, a CCTV survey shows whether roots or a damaged section are the cause.
06
Where an outside drain is shared with a neighbouring property or crosses the boundary, a CCTV survey confirms where the blockage sits and helps establish who is responsible.
How TO
For a minor outside blockage it is worth trying a few things before you call. Lift the drain cover and clear any visible debris, leaves, silt or build-up around the gully by hand while wearing gloves. A pair of drain rods pushed along the run can shift a blockage a little further down. A garden hose or a bucket of hot water can flush the loosened debris through.
What we would not recommend is chemical drain cleaner, which rarely clears a full blockage, damages pipework over time, and is hazardous where the drain overflows into a garden. If the drain is still overflowing, if the chamber or manhole is backing up, or if more than one outside drain is affected, the blockage is deeper in the main run and needs professional clearing. That is the point to call us rather than keep working at it from the surface.
Process
Step 1
Call or book online and describe which outside drain is affected, whether it is a gully, a chamber or a channel drain, and whether it is slow, blocked or overflowing.
Step 2
Same day service is standard. The engineer arrives with jetting and CCTV on the van, so the job is usually completed in a single visit.
Step 3
The engineer finds where the blockage sits and what is causing it. Where the cause is not obvious or the drain keeps blocking, a CCTV survey shows what is happening underground.
Step 4
Using high-pressure water jetting or drain rods as appropriate, the engineer clears the blockage completely. We do not use chemical drain cleaners, which corrode pipework over time.
Step 5
The engineer checks the drain is flowing freely before leaving, and where a CCTV survey was carried out, shows you what was found.
Step 5
Every repair is backed by our 12-month labour guarantee. If a fault we fixed recurs within that period, we return at no extra cost.
Methods
Jetting clears an outside drain by blasting the blockage apart and flushing it away, clearing the full width of the pipe rather than punching a narrow hole through it. It handles silt, leaves, grease, root ingress and general build-up, and is the professional standard for external drain clearing.
Outside drains often block because of something structural, roots through a joint, a displaced connection, or a collapsed section. A CCTV camera fed into the drain shows exactly what is going on underground, so the drain is repaired rather than repeatedly cleared. It also provides evidence where a blockage relates to a shared drain, a boundary dispute or an insurance claim.
Pricing
0800 Homefix does not charge a call out fee for outdoor drain unblocking. You pay for the engineer’s labour from the moment work begins, starting with the first hour, so your money goes toward clearing the drain rather than the visit itself. Where the blockage is cleared within the first hour and no further work is needed, there is nothing more to pay.
Where a drain needs jetting, a CCTV survey or a repair, the engineer explains what has been found and agrees the cost with you on site before going ahead. A small uplift applies to evenings, weekends and bank holidays, stated when you call and confirmed before the engineer travels. Full rates are published on our rates page.
FAQ
Some Questions homeowners, landlords, and tenants typically ask before booking one of our plumbers in London.
We clear outside drains with high-pressure water jetting, which blasts the blockage apart and clears the full width of the pipe, and with drain rods where more appropriate. For a blocked gully we also clear debris by hand. Where a drain keeps blocking, a CCTV survey shows the cause underground so it can be fixed properly. We do not use chemical drain cleaners, which damage pipework over time.
For a minor blockage you can lift the cover, clear visible debris from the gully by hand with gloves on, use drain rods to shift a blockage further down, and flush with a hose or hot water. Avoid chemical drain cleaners. If the drain is still overflowing, the chamber is backing up, or more than one drain is affected, the blockage is in the main run and needs professional clearing.
Recurring outside blockages usually have an underlying cause, a build-up of silt and leaves, grease from a kitchen waste, root ingress through a joint, or a displaced or collapsed section of pipe. Clearing the blockage without finding the cause means it returns. A CCTV survey confirms what is happening so the drain can be repaired rather than repeatedly cleared.
An overflowing outside drain that is backing up toward the property, flooding the garden, or posing a hygiene risk should be treated as urgent. We aim to reach genuine drainage emergencies within one hour, subject to availability. A slow outside drain that is not overflowing can usually be booked as a same day standard job.
Yes. We clear outside gullies, yard and driveway drains, rainwater and surface-water drains, inspection chambers and manholes. Where the blockage is in a shared or main drain, a CCTV survey confirms the location and cause.
Drains within your property boundary are usually your responsibility, while public sewers and lateral drains beyond the boundary are typically the water company’s. Many outside drains connect to a shared or public sewer, so a CCTV survey helps establish where the blockage sits and who is responsible for the repair. We can advise on this on site.
High-pressure water jetting is safe for sound pipework and is the professional standard for external drain clearing. Where an outside drain is old or already damaged, a CCTV survey identifies this first so the right approach is taken rather than jetting blind.
