How Much Is It to Unblock a Drain in Bristol?

If you’re Googling price, you want a straight answer and a working drain. Flow Sure Drains keeps it simple: Fixed price, No call-out fee, Same-day service across Bristol and nearby towns — and where possible, a 12-month free call-back on the same fault. We clear properly (not just poke a hole) and prove the result with CCTV when needed.

We’re Checkatrade members and we encourage you to read our Google reviews before you book anyone. You’ll see the same themes: clear quote, clean work, fast fix — without the “extras”. Many competitors still run hourly rates plus add-ons for jetting, CCTV, PPE, “disposal”, or “priority” slots. We don’t play that game. We agree a fixed price on arrival after a quick on-site check, then we get it flowing — end of.

What you’re actually paying for (and what’s included)

• Rapid diagnosis at the door (traps, first bends, chambers, interceptors).

• Mechanical clearance to break through wipes, fat collars, silt or paper snarls.

• HPWJ (High-Pressure Water Jetting) to clean the pipe wall to full bore (not a skinny tunnel).

• CCTV confirmation when needed, so you can see the result and any underlying issues.

• Prevention tips matched to your set-up.

• No call-out fee — you’re not paying us to knock.

• Fixed price agreed on arrival — you know the number before we begin.

• Where possible: 12-month free call-back on the same fault*.

*Fair use: call-back applies where the line is sound and used normally. Structural defects, foreign objects, building debris, misuse (e.g., wipes/fats poured in after the visit) or third-party works are excluded. We’ll explain on site in plain English.

Why we don’t publish a “price menu”

Bristol’s stock is a mix of Victorian clay terraces, post-war estates with long garden runs, shared stacks, and leaf-heavy gullies. Two jobs that look the same online can be very different in the ground. Publishing a flat sticker price is usually marketing fluff. Our way is honest: arrive the same day, assess, give a fixed price you approve, then clear it properly — with no call-out, no hourly meter running, and no add-on surprises.

---

What affects the price (in plain English)

• Access & length of run — long gardens/hidden chambers may take longer.

• Pipe material & age — clay with displaced joints behaves differently to newer plastic.

• Location of the restriction — first bend vs. deep main run or an interceptor trap.

• What’s in there — fat, wipes, sanitary items, coffee grounds, building debris, roots.

• Shared vs private line — shared lines need careful proof and neighbor comms.

We check these fast and then give you a fixed price. No hourly watch-tapping, no “jetting extra”.

---

How we keep your cost down (and the fix lasting)

1. Fast, accurate diagnosis — we target the real restriction, not guesswork.

2. HPWJ deep clean — cleans the pipe wall, so it stays clear longer.

3. Stocked vans — if a simple part helps, we likely have it.

4. Evidence — CCTV and photos reduce repeat visits and disputes on shared lines.

5. Practical prevention — small habits that save you ringing again.

Bristol symptoms (what a real blockage looks like)

• Kitchen sink slowing to a glug, then belching air.

• Toilet level rising and settling slowly; gurgles elsewhere.

• External gully filling during a normal shower — water lapping at the cover.

• Sewer smells by the back door or utility, especially after rain.

• Two fixtures misbehaving together = the main run is restricting, not just a trap.

Left alone, fats harden, wipes compact, and silt settles. In older lines with interceptor traps or displaced clay joints, a minor clog becomes a full standstill fast. Act today — cleaner, cheaper, and far less hassle with neighbours.

---

Safe things you can try before we arrive

• Kitchen trap check: bowl under, unscrew carefully, clear and re-seat seal.

• Gully test: lift the grid (if safe), run a tap — if it fills, restriction is downstream.

• Pause chemicals: caustic/acid often makes it worse; if used, tell us so we can work safely.

• Red flags (call now): toilet rising/overflowing, multiple fixtures slow together, repeat blockage within days.

What we actually do (plain English, first-visit mindset)

1) Diagnose (5–10 mins).
From symptoms to cause: traps/first bends, external chambers, interceptors (common in Bristol), then the run to boundary. We confirm your fixed price up-front.

2) Mechanical clearance (10–20 mins).
Rods and powered cutters break through wipes, fat collars, silt ridges and paper snarls.

3) HPWJ (10–25 mins).
High-Pressure Water Jetting scrubs the pipe wall and flushes residues (fat, coffee grounds, scale lips, early root hairs at clay joints). Result: a clean bore.

4) CCTV (when needed, 5–15 mins).
We prove the fix and check for defects: displaced joints, cracked collars, settled interceptors, root ingress, foreign objects. Clips available — ideal for landlords/agents.

5) Prevention briefing (2 mins).
Simple, specific tweaks for your set-up. No lectures.

Practical prevention tips you’ll actually keep

• Bin wipes — even “flushable” ones snag on clay joints.

• FOG discipline: Fats, Oils, Grease → cool, scrape, bin.

• Leaf season: sweep gullies weekly.

• Hot-rinse habit: short hot rinse after heavy washing-up.

• Don’t bury access: keep inspection covers clear.

• Coffee grounds: bin them; they cement in traps/first bends.

• Hair guards: cheap mesh guards keep shower lines clear.
