Question 1

What causes blocked drains most often in the UK?

Accepted Answer

The main causes are fat, oil, and grease (FOG) buildup, wet wipes and sanitary items (even those marked "flushable"), food waste, hair and soap scum, and outdoor debris such as leaves, silt, and moss. In older properties, collapsed or misaligned pipes are also common.

Question 2

What are the signs of a blocked drain?

Accepted Answer

Typical signs include slow-draining sinks and showers, gurgling noises from plugs or toilets, persistent bad smells, water backing up into fixtures, and outdoor symptoms such as a smelly gully or an overflowing manhole cover.

Question 3

What should I do first if I have a blocked drain?

Accepted Answer

Stop using water in the affected area immediately to prevent overflow. If it is a toilet, consider turning off the stopcock if there is a flooding risk. Avoid pouring harsh chemicals down a backed-up drain — they are rarely effective and can damage older pipework. Call a professional if there is any active flooding or sewage.

Question 4

Why does my drain keep blocking again and again?

Accepted Answer

Repeat blockages almost always indicate an underlying structural issue — a partial collapse, a cracked pipe, root ingress, or a belly in the pipe where water pools and sludge accumulates. A CCTV drain survey is the definitive diagnostic tool for recurring blockages.

Question 5

Can tree roots really block drains?

Accepted Answer

Yes. Fine root hairs enter through microscopic cracks or displaced joints. Once inside, they expand to trap debris, causing recurring blockages and slow drainage — particularly noticeable after heavy rainfall. Root-affected pipes usually require CCTV inspection and targeted remediation such as CIPP relining to create a seamless, root-proof barrier.

Question 6

Can blocked drains damage my home?

Accepted Answer

Absolutely. Sewage backups can flood internal spaces, damage flooring, walls, and joists, and create serious sanitation risks. Outside overflows can saturate and undermine ground beneath driveways or patios. Acting fast minimises structural damage.

Question 7

Do you offer 24/7 emergency drain unblocking?

Accepted Answer

Yes. We operate 24 hours a day, 7 days a week including bank holidays. Emergency attendance is prioritised for active flooding, sewage overflow, properties with a single working toilet, and commercial sites at operational risk.

Question 8

How fast can you attend?

Accepted Answer

Our engineers are positioned across the UK to target a 60-minute response for emergency calls. Actual arrival depends on engineer availability in your specific area and traffic conditions. To get an accurate ETA, call our 24/7 dispatch line with your postcode.

Question 9

What information do you need when I call?

Accepted Answer

To dispatch help as quickly as possible, have ready: your postcode and property type (residential or commercial), what is blocked (toilet, sink, outside drain, manhole), whether there is active flooding or visible sewage, how many fixtures are affected, and details of any recent building or landscaping work.

Question 10

Who is responsible — homeowner, landlord, or water company?

Accepted Answer

Drainage within your property boundary is generally the homeowner or landlord's responsibility. Shared or public sewers (typically beyond your boundary, serving multiple properties) are the responsibility of the local water authority — for example, Thames Water in London or Severn Trent in the Midlands. A CCTV survey can definitively confirm which pipes are your responsibility.

Question 11

What methods do you use to unblock drains?

Accepted Answer

We use drain rodding for simple, accessible obstructions; high-pressure water jetting (HPWJ) at up to 4,000 PSI for grease buildup and fatbergs; specialist root-cutting heads for root ingress; and CCTV robotic inspection to diagnose structural faults on any drain that is recurring or slow to clear.

Question 12

Is high-pressure water jetting safe for pipes?

Accepted Answer

Yes, when performed by a trained, WJA-certified engineer. Jetting is far safer than repeated chemical use and significantly more effective at stripping scale, grease, and silt back to the full bore of the pipe. Our engineers modulate pressure based on the pipe material — critical for older clay or pitch fibre systems.

Question 13

Are drain unblocking chemicals safe?

Accepted Answer

Generally no. Most store-bought caustic chemicals are corrosive and can accelerate the degradation of older clay, pitch fibre, or even modern PVC pipework. They are rarely effective against compacted fatbergs or structural blockages. High-pressure jetting is a cleaner, safer, and more permanent solution.

Question 14

What is the difference between drain unblocking and drain cleaning?

Accepted Answer

Unblocking is the immediate removal of a specific obstruction that is causing a backup. Drain cleaning (or descaling) involves stripping away decades of accumulated grease, limescale, and silt to restore 100% bore capacity. Cleaning reduces future call-out frequency and is often part of a planned preventative maintenance (PPM) programme.

Question 15

How long does it take to unblock a drain?

Accepted Answer

Most standard blockages — a blocked toilet, kitchen sink, or outside gully — are cleared within one to two hours. If the issue involves root ingress, a structural collapse identified by CCTV, or requires follow-on relining work, the total job time will be longer. We always provide a realistic time estimate on arrival.

Question 16

When do I need a CCTV drain survey?

Accepted Answer

Request a CCTV survey if you have frequent blockages, slow drainage across multiple fixtures simultaneously, persistent bad smells that return after clearance, you are buying or selling a property, your mortgage lender requires it, or you are planning an extension or build-over a sewer.

Question 17

What does a CCTV survey find?

Accepted Answer

Our robotic HD cameras identify root ingress, displaced or open joints, longitudinal cracks, partial or full collapses, bellies in the pipe, build-over compliance issues, and confirm exactly which pipes fall within your ownership responsibility versus the water authority's.

Question 18

What is a WinCan report and do I need one?

Accepted Answer

WinCan VX is the industry-standard pipe inspection reporting software. A WinCan-compliant report provides a precise, millimetre-level log of every pipe surveyed — including material, condition, and defect classification. It is the format required by UK mortgage lenders, insurers, and water authorities. We produce full WinCan reports as standard on all structural surveys.

Question 19

What is CIPP relining and does it work?

Accepted Answer

Cured-In-Place Pipe (CIPP) relining inserts a resin-impregnated felt liner into the damaged pipe, which is then inflated and cured to create a seamless, jointless structural sleeve inside the existing host pipe. It is effective for cracks, root ingress, and displaced joints — with a design life of 50 years. It requires zero excavation, making it ideal for pipes beneath driveways, floors, and gardens.

Question 20

Can all pipes be relined?

Accepted Answer

Most pipes can be relined provided they retain enough structural integrity to hold the liner in shape during curing. Pipes that have fully collapsed or flattened (pancaked) may require targeted excavation first. A CCTV survey before any relining project confirms suitability and allows us to accurately scope the work.

Question 21

How much does emergency drain unblocking cost in the UK?

Accepted Answer

Pricing depends on the time of day, access difficulty, blockage complexity, and the method required. We provide transparent, fixed-price quotes once we have assessed the symptoms and access. There are no call-out fees. Call our dispatch line or use the online quote form for an immediate estimate.

Question 22

Do you guarantee the work?

Accepted Answer

Yes. We back every unblocking job with a return guarantee covering the same drain and blockage type within the stated period. Separate warranty terms apply to CIPP relining and structural repair works. Our team will confirm the exact terms before starting any job.

Question 23

What can I do to prevent blocked drains?

Accepted Answer

Never pour fat, oil, or grease down kitchen sinks. Never flush wipes — even those labelled "flushable" do not break down in UK sewer systems. Use strainers in sinks and showers to catch debris. Clear leaves from external gullies in autumn. For high-risk commercial kitchens or older properties, schedule periodic high-pressure jetting as preventative maintenance.

Question 24

Can I unblock a drain myself?

Accepted Answer

For very minor clogs — such as a hair blockage in a shower trap — a plunger or hand rod can work. However, if water is backing up from multiple fixtures, the blockage is in an outside drain or manhole, or the issue has recurred before, professional intervention is required. Attempting to rod a structural blockage or root ingress can make the situation significantly worse.

Question 25

How often should I clear my gutters?

Accepted Answer

For most residential properties, once a year in late autumn after leaf fall is sufficient. Properties near large trees, with moss growth on the roof, or with flat roofs may need clearing twice a year. For commercial buildings, we recommend a Gutter Management Programme with scheduled annual clears and a HD camera verification record.

Question 26

What is jet washing and when do I need it?

Accepted Answer

Jet washing uses industrial-grade pressure washers (up to 4,000 PSI) to remove organic growth, algae, oil stains, and atmospheric soiling from patios, driveways, and commercial walkways. It restores surface grip, prevents slip hazards, and removes the biological matter that causes long-term surface decay. We recommend an annual clean for external surfaces in the UK climate.

Question 27

How often should a septic tank be emptied?

Accepted Answer

Most septic tanks require desludging every 12 to 24 months, depending on tank size and household usage. Leaving a tank too long risks drainage field failure, ground contamination, and significant remediation cost. We provide a Waste Transfer Note (WTN) with every emptying, as required by Environment Agency regulations.

Question 28

What happens if I do not empty my septic tank?

Accepted Answer

An unemptied tank will eventually overflow into the drainage field, saturating the soakaway and potentially causing ground-level sewage emergence. This is both an Environment Agency compliance issue and a significant structural remediation cost. Regular desludging is the most cost-effective way to protect the entire system.
