Drilling into a basin and hitting a pipe: a €60 to €250 mistake
Four wall plugs, a drill and a geyser. That's how one of the most expensive household stories you can tell without having home insurance begins. A homeowner describes how, while installing a basin on a cabinet, the first three anchors went in without a problem, but the fourth hit something harder than usual. As he tightened the screw, drops of water began to appear. When he loosened it to assess the damage, the leak turned into a violent jet that flooded the bathroom in the seconds it took him to shut off the stopcock. The result: no hot water, no basin, and a burst pipe behind the tiling.
The next question is the usual one: how much does this cost? The answer, based on experience with similar cases, ranges from the €60 charged by a trusted plumber to the €250 of a repair that includes brickwork. In the story in question, a professional who was a friend of a neighbour offered to do it for €60, though with a week's wait. Other accounts mention €180 for chasing out the wall, replacing the pipe and patching with plaster, no invoice, over two visits. And some point to €160-180 if the tile also has to be replaced.
How much does it cost to repair a pipe drilled through by a drill?
The range depends on three factors: whether the pipe is copper or iron, whether the tiling has to be replaced, and whether the professional issues an invoice. The cheapest documented case is a plumber who charges €60 for labour and basic materials, without VAT or warranty. The most expensive, €250 excluding VAT, includes guasonry work. In between are the €180 charged by a multi-service company that chased into the wall from the living room side to avoid breaking tiles and patched with plaster, though the painting was left to the owner.
The material matters. If the pipe is copper, the standard repair involves cutting out the damaged section, sanding it, applying flux and solder, and soldering in a coupling. If it's iron, things get more complicated and the cost rises. Some opt for Gebo-type repair couplings, which are fitted without soldering, but installing them requires space around the pipe and they don't always fit.
The quick fix that can't take the pressure
The story includes an attempt at a temporary solution that ended badly. After the initial leak, an attempt was made to plug the hole with putty. When the stopcock was carefully peine, the makeshift patch shot off violently and flooded the bathroom again. The lesson is clear: DIY patches don't withstand the pressure of the mains. A professional consulted confirmed it: no cheap patches, even soldered ones, because they don't hold.
A no-dig alternative does exist, but it's limited. These are products that are inserted into the pipe and create an inner film. They are designed for pores and small cracks in old installations, not for an 8-millimetre hole made with a drill bit. In this case, mechanical repair is unavoidable.
Home insurance, the great forgotten one
The absence of home insurance is the factor that turns a breakdown into a financial problem. In the case described, there is no policy in place. Home insurance policies usually cover plumbing failures, but there are doubts about whether they would cover damage caused by a drill. The answer depends on the terms of the policy and the loss assessment. In Germany, for example, the legal system is different and the owner is usually liable for damage caused by negligence.
The cost of repairing the damp in the flat below is another unknown. With suspended ceilings, the water may not reach the flat underneath, but if it does, the bill gets added on. Without insurance, everything comes out of your own pocket.
Metal detectors: between DIY and prevention
The conversation turns to prevention. Lidl's metal detectors, which cost around €6, are mentioned as a useful tool for avoiding drilling into pipes. However, some point out that a simple beep isn't enough: models that indicate the direction of the object cost between €130 and €180, beyond many people's budget. The recommendation is clear: before drilling, find out where the pipes run.
The thread leaves one question open: how much would it have cost to take out home insurance before picking up the drill?
