Drainage work runs on urgency and diagnosis more than most trades, and understanding both from the start shapes how you price and how you avoid disputes over who actually owns a problem.
Invest in CCTV survey equipment early
A proper drain survey is what tells you whether a blockage needs simple rodding, high-pressure jetting, or points to a structural issue needing excavation. Without it, you're guessing at the right fix. With it, you can price accurately and explain the job to a customer with confidence.
Learn to explain the difference between clearance methods
Rodding, jetting, and excavation are different tiers of job, not interchangeable terms for "unblocking a drain." Customers who don't understand why one callout costs more than another usually just haven't had the difference explained. Do that clearly and most pricing questions disappear.
Learn the local rules on shared and private drain responsibility in detail. It's a genuine, common source of dispute, and being the engineer who can explain it accurately builds trust fast.
Know who's actually liable before quoting a fix
A shared lateral drain or a public sewer beyond the boundary may be the water company's responsibility, not the customer's. Identify this correctly, and you protect both you and the customer from paying for a repair that was never theirs to fund.
Flag recurring problems honestly, even if it means a smaller job today
A customer calling you out repeatedly for the same blockage, often from tree root ingress, deserves an honest recommendation for a proper repair instead of another quick clear. It's a bigger job to suggest, but it's also what turns a one-off callout into a trusted, repeat relationship.
Be genuinely available for emergencies
Blocked drains often can't wait, and being known locally as reliably available for urgent calls builds a strong reputation faster than almost any other marketing effort in this trade.
Invest in your own equipment early
Owning your own CCTV and jetting equipment, instead of subcontracting surveys out, lets you price and schedule jobs on your own terms and keeps more of the job's value with you.
Offer preventative contracts to commercial customers
Restaurants and other food businesses with grease traps face recurring blockage risk that a one-off emergency callout doesn't solve long-term. A scheduled preventative maintenance contract, regular jetting before a blockage happens instead of reactive clearing after, is genuinely valuable to a business that can't afford a closed kitchen, and it converts unpredictable emergency income into steady, contracted revenue.
Approach restaurants and cafes directly with a preventative contract offer instead of waiting for an emergency call. Most have never been asked and don't realise the option exists until a blockage has already cost them a service.
