Drainage & Sewer Specialists
Marketing for drainage & sewer specialists
Drainage is two businesses sharing a van. One is the panic call at eleven at night about a toilet backing up, priced in the low hundreds and won by whoever answers first. The other is surveys, lining and excavation, priced in the thousands and won on a report the customer can hand to an insurer or a solicitor. Advertising them together wastes money on both.
In short
Marketing for drainage & sewer specialists in the UK turns on three things that are specific to the trade. Reactive domestic work is small and fast: a straightforward unblock is commonly £90 to £250, and jetting a longer run with a van pack pushes towards £180 to £400. A CCTV survey with a written report sits at £150 to £400, with pre-purchase surveys clustering around the middle of that. Paid search owns the emergency half outright. The biggest source of wasted spend is diy and chemical fixes, searches such as how to unblock a drain and drain rods screwfix, which has to be negatived out before the budget means anything.
The economics that should drive the budget
Reactive domestic work is small and fast: a straightforward unblock is commonly £90 to £250, and jetting a longer run with a van pack pushes towards £180 to £400. A CCTV survey with a written report sits at £150 to £400, with pre-purchase surveys clustering around the middle of that. Then the values jump. A localised patch repair is £600 to £1,500, no-dig lining of a run runs £1,500 to £6,000, and excavation with reinstatement of a drive or path is £3,000 to £15,000. Commercial planned maintenance, gully rounds and grease management sit on annual contracts anywhere from £500 to several thousand.
Margins diverge as sharply as the prices. A reactive unblock is a van, a jetter and an hour, so gross margin above sixty per cent is normal. Excavation drops to twenty-five or thirty-five per cent once you are paying for a mini digger, muck away, concrete and a reinstated surface. Conversion is where reactive work is remarkable: an emergency call answered live, by a person, with an attendance time the same day, converts at roughly seventy to eighty-five per cent. A survey or repair quote sent by email converts at about one in three.
So the emergency arithmetic looks like this. A £160 average at sixty-five per cent leaves £104 of gross profit, and at a three-in-four conversion on answered calls each ringing phone is worth around £78. A cost per call of £15 to £40 is comfortable on that basis. The real return, though, is downstream: a meaningful share of unblocks reveal a defect, and a customer who is shown the footage buys a survey and sometimes a five-figure repair. Judge the channel on revenue per acquired property, not per job.
Seasonality
Demand is weather-led and lumpy. Autumn leaf fall silts gullies and blocks surface water runs from late October. The week between Christmas and New Year produces a reliable wave of kitchen blockages caused by fat and food waste. Deep cold in January and February cracks shallow pipework and the failures appear during the thaw. Prolonged rain generates the sharpest spikes of all, often within forty-eight hours of a named storm, and that is precisely when budgets that are capped daily run out by lunchtime.
The survey side of the business runs on a completely different clock, because it tracks house sales rather than rainfall. It climbs through spring and early summer with transaction volume and softens in December. That counter-cycle is useful: when reactive demand is quiet in July, survey and repair marketing should be carrying the diary, and the account should be built so budget can move between the two without rebuilding anything.
What we configure
- Emergency call-only campaigns dayparted across evenings and weekends
- Water company and shared-sewer responsibility terms excluded from paid
- A published attendance window rather than a vague twenty-four-hour claim
- Call tracking that records answered versus missed by hour of day
- Surge budget rules so storm weeks are not capped out by mid-morning
- A survey landing page that shows a sample report and its turnaround
- Commercial contract campaign kept on business hours and a wider radius
What people actually search, and what it is worth
| Intent | Typical search | Value | How we handle it |
|---|---|---|---|
| Emergency blockage | blocked drain [town], emergency drain unblocking, toilet backing up outside, sewage in garden, drain overflowing | Immediate, decided in minutes | Call-only ads and call extensions with a stated attendance window, bid up hard during evenings and weekends. The customer is ringing three numbers in ninety seconds and does not read anything, so the phone must be answered by a human. |
| Pre-purchase and condition survey | drain survey [town], CCTV drainage survey cost, homebuyer drain survey, drain survey before buying a house | Steady, deadline-driven | Search plus content, because these buyers are researching what a survey involves and who it satisfies. A page explaining what the report contains and how quickly it is issued converts better than any price-led ad. |
| Repair, lining and root damage | collapsed drain repair, drain lining cost, root ingress in drain, cracked drain pipe under patio | Highest value, longest decision | Its own campaign with a landing page comparing no-dig lining against excavation. This buyer usually already has a survey from somebody, so the job is to be the firm that explains the options rather than the one that quotes fastest. |
| Commercial and facilities | commercial drainage contractor, grease trap emptying, gully cleaning contract, pump station maintenance | Recurring, contracted | Wider radius, business hours weighting, and copy about response SLAs, out-of-hours cover and site accreditations. Facilities managers are buying reliability and paperwork, not a price per hour. |
Where the budget leaks
Every sector attracts searches that can never become a customer. These are the ones specific to drainage & sewer specialists, and they go into the negative keyword list before launch rather than after the first invoice.
| Category | Example searches | Why it costs you |
|---|---|---|
| DIY and chemical fixes | how to unblock a drain, drain rods screwfix, caustic soda for drains, one shot drain cleaner, plunger for toilet | Somebody standing in a hardware aisle at the cheap end of a problem. High volume, permanently unprofitable, and it spikes on exactly the wet weekends you want budget available. |
| Water company responsibility | report a blocked sewer, who is responsible for shared drains, is my drain public or private, [water company] blocked drain | The single biggest leak in a drainage account. Lateral drains and shared sewers transferred to the water companies in 2011, so a large share of these searchers are entitled to a free attendance. |
| Design, regulation and self-build | soakaway building regulations, part H drainage, septic tank rules, land drainage design, percolation test calculator | Architects, self-builders and homeowners reading legislation. The occasional real job hides in here, but the ratio makes broad targeting on these terms indefensible. |
| Equipment, training and recruitment | van pack jetter for sale, drainage engineer jobs, jetting training course, CCTV crawler camera price | Competitors kitting out, engineers looking for a move, and trainees. It shares your entire technical vocabulary and converts at nothing. |

Call 07443 392243WhatsAppWhat the buyer is actually checking
The emergency caller checks almost nothing, and that is the point. They want a number that connects to a person, an honest answer about when a van can be there, and a price band before anybody sets off. Anything that adds friction loses the job to the next result. What they are quietly afraid of is the engineer who arrives, looks at the drain and produces a figure four times what was implied on the phone, because that has happened to somebody they know.
The survey and repair buyer is the opposite and reads everything. They want to know whether the report includes actual footage and coded observations rather than a paragraph of opinion, whether it will satisfy a lender, a solicitor or an insurer, and whether the firm that surveys is the firm that repairs, since they suspect a survey sold by a repair company will always find a repair. Showing a genuine sample report, with the customer details removed, answers more of that suspicion than any accreditation logo.
Which channel wins here
Paid search owns the emergency half outright. The intent is immediate, the map pack and call-only formats take most of it, and the difference between a good and a poor account is usually dayparting and answered-call rate rather than keywords. Google Business Profile matters as much as the ads, because a large share of blocked drain searches never leave the results page.
Organic search is where the survey and repair side is built, and it has a peculiar advantage: the confusion in this sector is so widespread that genuinely useful pages about drain ownership, what a CCTV report shows and when lining beats excavation attract links and rank for years. Some of that traffic is the free-fix audience, which is fine unpaid and ruinous paid. Meta does very little for reactive demand, since nobody scrolls a feed while their garden fills up, though it has a modest role in reaching facilities and property managers for contract work.
Why keeping them matters more than winning them
Contracts are the ballast. A commercial site on a scheduled gully or grease round is revenue that arrives whether or not it rains, and it routes efficiently because the visits are planned. One retail park or a portfolio of pubs can underwrite the fixed costs of a two-van operation, which is what allows the reactive side to be priced sensibly rather than desperately.
Referral sources in drainage are professional rather than social. Estate agents, surveyors, letting agents and insurance loss adjusters all need a drainage firm they can name without worrying, and each of them refers repeatedly rather than once. Cultivating six of those relationships produces more predictable work than any number of individual happy customers, because a homeowner has a blocked drain roughly once a decade.
The overlooked asset is the survey archive. Every property you have filmed is a known defect on a known address, and a proportion of the customers who deferred a repair will act within two years, usually when they sell. A simple follow-up on deferred repairs turns work you have already paid to find into work you get for the cost of a phone call.
Questions from drainage & sewer specialists
How do I stop paying for people whose water company should attend?
By excluding the vocabulary that identifies them. Searches about shared sewers, reporting a blockage, public versus private drains and the water companies by name are dominated by people entitled to a free attendance since the 2011 transfer. Answer those questions helpfully in organic content, where the traffic costs nothing and builds authority, and keep them out of the paid account entirely.
Are emergency drainage leads worth bidding aggressively for?
Yes, provided the phone is answered. A typical unblock at £160 with a high labour margin leaves around £100 of gross profit, and answered emergency calls convert at three in four or better. The economics only break when calls ring out. A missed call in this trade is a total loss, because the caller moves straight to the next listing and never returns.
Should surveys and repairs be marketed separately from unblocking?
Separately, and ideally on different pages with different measurement. The unblock buyer decides in two minutes on availability; the repair buyer decides over a fortnight on evidence. Sharing a budget means the cheap, fast conversions consume it and your five-figure lining work never gets an impression. Split the campaigns and judge each on its own cost per acquired job.
What makes a drainage website rank when everyone offers the same thing?
Explaining what nobody else will. Drain ownership, what a coded CCTV report actually contains, when a patch liner is enough and when the ground has to come up, and honest ranges for each. Those pages earn links and hold rankings for years because they answer the questions people search before they are ready to buy, which is most of the volume in this sector.
