What to know before you book in Andover
Andover is a Hampshire town on the River Anton, covered by the SP10 and SP11 postcodes. Drainage work here splits into three broad jobs: clearing a blockage, finding out why it keeps coming back, and repairing the pipe that caused it. The first is a same-day callout. The second needs a camera survey — without one, a repeat blockage is being treated as a coincidence. The third is where quotes vary most, because relining, patch repair and full excavation solve the same symptom at very different costs and disruption.
Of the 5 firms listed here, 5 have published enough detail to answer the capability questions. Across the group, 51 customer reviews are recorded, averaging 5.0 out of 5. Where a firm serves Andover from outside the town, the address on the profile is their base, not a local depot — worth knowing if you are judging response time.
Two practical checks before anyone lifts a drain cover. First, confirm whether the blockage is in your private drain or the public sewer: water companies usually clear the public sewer at no cost to you, and a firm that does not ask is either inexperienced or hoping to bill you for work someone else owes. Second, ask for the fixed price in writing before jetting starts, including what happens if the jetter cannot clear it.
Questions people ask in Andover
Who offers 24/7 emergency drainage callout in Andover?
4 of the 5 firms listed for Andover state that they take emergency calls outside normal hours: Draintech Tankers. "Outside normal hours" means what each firm publishes — some answer the phone all night, others divert to an on-call engineer.
Can a Andover drainage company repair a drain without digging?
Yes — 2 firms list no-dig relining or lining for Andover. That matters where the drain runs under a driveway, conservatory or established garden, because the alternative is excavation and reinstatement.
How do I check a drainage firm before booking?
Ask three things: whether the price is fixed before work starts, whether the engineer is directly employed or subcontracted, and what the guarantee covers in writing. A firm that cannot answer all three on the phone is usually passing the job to someone else.
